20140026166
The present invention relates to a multimedia device technology, and more particularly, to a method of controlling a network TV capable of bookmarking at least one or more items and the network TV.
An image display device includes, for example, a function for receiving and processing a broadcast image viewable by a user. For example, the image display device displays a broadcast, which is selected by the user from among broadcast signals transmitted from a broadcast station, on a display. Currently, broadcasters are transitioning from analog to digital broadcasting from analog broadcasting around the world.
Digital broadcasting refers to broadcasting of digital video and audio signals. The digital broadcast has low data loss due to robustness against external noise, error correction, high resolution and a high-definition screen, as compared with an analog broadcast. In addition, digital broadcasting can provide a bidirectional service unlike analog broadcasting. Recently, a smart TV formed by combining functions of an image display device and multimedia device has been discussed.
A conventional image display device cannot rapidly access numerous pre-stored contents. For example, the conventional image display device has a limit in which a user needs to perform various steps in order to execute content downloaded by the user. In particular, in consideration of a situation in which memory performance of an image display device is gradually improved, there is a need for technology for readily managing several tens to several hundreds of contents.
An object of the present invention devised to solve the problem lies in a solution for more rapidly accessing homogeneous or heterogeneous items.
Another object of the present invention devised to solve the problem lies in a user interface for grouping and displaying items according to user preference.
Another object of the present invention devised to solve the problem lies in a graphical user interface (GUI) for outputting items classified into a plurality of ratings in the optimized form.
The object of the present invention can be achieved by providing a method of controlling a network TV for bookmarking at least one or more items, the method including receiving a first command for setting bookmarking of a currently executed item and a second command for selecting a rating of the bookmarked item, storing information for identifying the bookmarked item having the selected rating in a bookmarking memory according to the first command and the second command, receiving a third command for listing at least one or more bookmarked item, accessing the bookmarking memory, and displaying a first item having a first rating and a second item having a second rating separately from each other according to a rating for each respective item stored in the bookmarking memory
In another aspect of the present invention, provided herein is a network TV for bookmarking at least one or more items, the network TV including an interface for receiving a first command for setting bookmarking of a currently executed item and a second command for selecting a rating of the bookmarked item, a bookmarking memory for storing information for identifying the bookmarked item having the selected rating in a bookmarking memory according to the first command and the second command, a memory controller for accessing the bookmarking memory upon receiving a third command for listing at least one or more bookmarked item through the interface, and a display for displaying a first item having a first rating and a second item having a second rating separately from each other according to a rating for each respective item stored in the bookmarking memory
An embodiment of the present invention provides a solution for more rapidly accessing homogeneous or heterogeneous items.
Another embodiment of the present invention provides a user interface for grouping and displaying items according to user preference.
Another embodiment of the present invention provides a graphical user interface (GUI) for outputting items classified into a plurality of ratings in the optimized form.
More detailed advantageous effects of the present invention will be described below in detail.
Exemplary embodiments of the present invention will be described with reference to the attached drawings.
The terms “module” and “unit” attached to describe the names of components are used herein to help the understanding of the components and thus should not be considered as having specific meanings or roles. Accordingly, the terms “module” and “unit” may be used interchangeably.
A network TV as forth herein is an intelligent network TV equipped with a computer support function in addition to a broadcast reception function, for example. Since an Internet function is added to a broadcast reception function, the network TV may have user-convenient interfaces such as a handwriting input device, a touchscreen, or a spatial remote controller. Further, because the network TV supports wired or wireless Internet, it is capable of e-mail transmission/reception, Web browsing, banking, gaming, etc. by connecting to the Internet or a computer. To implement these functions, the network TV may operate based on a standard general-purpose operating system (OS).
Various applications can be freely added to or deleted from, for example, a general-purpose OS kernel of the network TV according to the present invention. Therefore, the network TV may perform a number of user-friendly functions. The network TV may be an Internet protocol TV, a hybrid broadcast broadband TV (HBBTV), a smart TV, etc. for example. The network TV is also applicable to smart phones.
Embodiments of the present invention will be described in detail with reference to the attached drawings, but it should be understood that they are merely illustrative of the present invention and should not be interpreted as limiting the scope of the present invention.
In addition, although the terms used in the present invention are selected from generally known and used terms, some of the terms mentioned in the description of the present invention, the detailed meanings of which are described in relevant parts of the description herein, have been selected at the discretion of the applicant. Furthermore, the present invention must be understood, not simply by the actual terms used but by the meanings of each term lying within.
As illustrated in
The CP 10 creates and provides a variety of content. The CP 10 may be, for example, a terrestrial broadcaster, a cable system operator (SO) or multiple system operator (MSO), a satellite broadcaster, or an Internet broadcaster, as illustrated in
Besides broadcast content, the CP 10 may provide various applications, which will be described later in detail.
The SP 20 may provide content received from the CP 10 as a service package. For instance, the SP 20 of
The SP 20 may unicast or multicast a service to the client 100. Unicast is a form of transmission in which data is sent from only one transmitter to only one receiver. In an example of unicast transmission, upon reception of a request for data from a receiver, a server transmits the data to only one receiver. Multicast is a type of transmission or communication in which a transmitter transmits data to a specific group of receivers. For example, a server may transmit data to a plurality of pre-registered receivers at one time. For multicast registration, the Internet group management protocol (IGMP) may be used.
The NP 30 may provide a network over which a service is provided to the client 100. The client 100 may construct a home network end user (HNED) and receive a service over the FINED.
Content transmitted in the above-described system including the network TV may be protected through conditional access or content protection. CableCARD and downloadable conditional access system (DCAS) are examples of such conditional access or content protection systems.
The client 100 may also transmit content over a network. In this case, unlike the above description, in an opposite way, the client 100 serves as a CP and thus the CP 10 may receive content from the client 100. Therefore, an interactive content service or data service can be provided.
As illustrated in
The network TV 100 includes, for example, a broadcast interface 101, a section filter 102, an application information table (AIT) filter 103, an application data processor 104, a broadcast data processor 111, a media player 106, an Internet protocol (IP) processor 107, an Internet interface 108, and a runtime module 109.
The network TV 100 receives AIT data, real-time broadcast content, application data, and stream events through the broadcast interface 101. The real-time broadcast content may be referred to as linear Audio/Video (A/V) content.
The section filter 102 performs section filtering on the four types of data received through the broadcast interface 101, and outputs the AIT data to the AIT filter 103, the linear A/V content to the broadcast data processor 111, and the stream events and application data to the application data processor 104.
Meanwhile, the network TV 100 receives non-linear A/V content and application data through the Internet interface 108. The non-linear A/V content may be, for example, content on demand (CoD) application.
The non-linear A/V content and the application data are transmitted to the media player 106 and the runtime module 109, respectively.
The runtime module 109 includes, for example, an application manager and a browser as illustrated in
The SP performs an SP discovery operation (S301). The network TV transmits an SP attachment request signal (S302). Upon completion of attachment to the SP, the network TV receives provisioning information from the SP (S303). Further, the network TV receives master system information (SI) tables (S304), receives virtual channel map tables (S305), receives virtual channel description tables (S306), and receives source tables from the SP (S307).
SP discovery will be described in more detail.
SP Discovery is a process by which SPs that provide IPTV services search for servers providing services to the SPs.
In order to receive information (e.g., SP discovery information) about the service discovery (SD) servers, an SD server address list can be detected, for example, using three methods, specifically use of an address preset in the network TV or an address manually set by a user, dynamic host configuration protocol (DHCP)-based SP discovery, and domain name system service (DNS SRV)-based SP discovery. The network TV accesses a specific SD server using the SD server address list obtained through one of the above three methods and receives an SP discovery record from the specific SD server. The service provider discovery record includes information needed to perform service discovery on an SP basis. The network TV then starts a service discovery operation using the SP discovery record. These operations can be performed in a push mode or a pull mode.
The network TV accesses an SP attachment server specified by an SP attachment locator included in the SP discovery record and performs a registration procedure (or a service attachment procedure).
Further, after accessing an authentication service server of an SP specified by an SP authentication locator and performing an authentication procedure, the network TV may perform a service authentication procedure.
Once service attachment is successfully completed, a server may transmit data to the network TV in the form of a provisioning information table.
During service attachment, the network TV may include an identifier (ID) and location information thereof in data and transmit the data to the service attachment server. Thus the service attachment server may specify a service that the network TV has subscribed to based on the ID and location information. In addition, the service attachment server provides, in the form of a provisioning information table, address information from which the network TV can obtain service information (SI). The address information corresponds to access information about a Master SI Table. This method facilitates provision of a customized service to each subscriber.
The SI is divided into a master SI table record for managing access information and version information about a virtual channel map, a virtual channel map table for providing a list of services in the form of a package, a virtual channel description table that contains details of each channel, and a source table that contains access information about actual services.
A Master SI Table contains information about the location and version of each virtual channel MAP.
Each virtual channel MAP is identified by its virtual channel MAP identifier. Virtual channel MAP version specifies the version number of the virtual channel MAP. If any of the tables connected to the master SI table shown in
For example, when the source table is changed, the version of the source table is incremented and the version of the virtual channel description table that references the source table is also incremented. In conclusion, a change in any lower table leads to a change in its higher tables and, eventually, a change in the master SI table.
One master SI table may exist for each SP. However, in the case where service configurations differ for regions or subscribers (or subscriber groups), an SP may have a plurality of master SI tables in order to provide a customized service on a unit basis. Thus it is possible to efficiently provide a customized service to a subscriber through the master SI table according to a region in which the subscriber is located and subscriber information regarding the subscriber.
A virtual channel Map table may contain one or more virtual channels. A virtual channel Map includes not only details of the channels but information about the locations of the details of the channels. In the virtual channel Map table, virtual channel description location specifies the location of a virtual channel description table including the details of the channels.
The virtual channel description table contains the details of the virtual channels. The virtual channel description table can be accessed using the virtual channel description location of the virtual channel Map table.
A source table provides information necessary to access actual services (e.g., IP addresses, ports, AV codecs, transmission protocols, etc.) on a service basis.
The above-described master SI Table, the virtual channel Map table, the virtual channel description table and the source table are delivered in four logically separate flows, in a push mode or a pull mode. For version management, the master SI table may be multicast and thus version changes can be monitored by receiving a multicast stream.
A network TV 700 includes a network interface 701, a transmission control protocol/Internet protocol (TCP/IP) manager 702, a service delivery manager 703, a demultiplexer (DEMUX) 705, a program specific information (PSI) & (program and system information protocol (PSIP) and/or SI) decoder 704, an audio decoder 706, a video decoder 707, a display A/V and on screen display (OSD) module 708, a service control manager 709, a service discovery manager 710, a metadata manager 712, an SI & metadata database (DB) 711, a user interface (UI) manager 714, and a service manager 713.
The network interface 701 transmits packets to and receives packets from a network. Specifically, the network interface 701 receives services and content from an SP over the network.
The TCP/IP manager 702 is involved in packet reception and transmission of the network TV 700, that is, packet delivery from a source to a destination. The TCP/IP manager 702 classifies received packets according to appropriate protocols and outputs the classified packets to the service delivery manager 705, the service discovery manager 710, the service control manager 709, and the metadata manager 712.
The service delivery manager 703 controls reception of service data. For example, when controlling real-time streaming data, the service delivery manager 703 may use the real-time transport protocol/real-time transport control protocol (RTP/RTCP). If real-time streaming data is transmitted over RTP, the service delivery manager 703 parses the received real-time streaming data using RTP and transmits the parsed real-time streaming data to the DEMUX 705 or stores the parsed real-time streaming data in the SI & metadata DB 711 under the control of the service manager 713. In addition, the service delivery manager 703 feeds back network reception information to a server that provides the service using RTCP.
The DEMUX 705 demultiplexes a received packet into audio data, video data and PSI data and transmits the audio data, video data and PSI data to the audio decoder 706, the video decoder 707, and the PSI & (PSIP and/or SI) decoder 704, respectively.
The PSI & (PSIP and/or SI) decoder 704 decodes SI such as PSI. More specifically, the PSI & (PSIP and/or SI) decoder 704 receives and decodes PSI sections, PSIP sections or SI sections demultiplexed by the DEMUX 705.
The PSI & (PSIP and/or SI) decoder 704 constructs an SI DB by decoding the received sections and stores the SI DB in the SI & metadata DB 711.
The audio decoder 706 and the video decoder 707 decode the audio data and the video data received from the DEMUX 705 and output the decoded audio and video data to a user through the display A/V and OSD module 708.
The UI manager 714 and the service manager 713 manage the overall state of the network TV 700, provide UIs, and manage other managers.
The UI manager 714 provides a graphical user interface (GUI) in the form of an OSD and performs a reception operation corresponding to a key input received from the user. For example, upon reception of a key input signal regarding channel selection from the user, the UI manager 714 transmits the key input signal to the service manager 713.
The service manager 713 controls managers associated with services, such as the service delivery manager 703, the service discovery manager 710, the service control manager 709, and the metadata manager 712.
The service manager 713 also creates a channel map and selects a channel using the channel map according to the key input signal received from the UI manager 714. The service manager 713 sets the audio/video packet ID (PID) of the selected channel based on SI of the channel received from the PSI & (PSIP and/or SI) decoder 704 in the demultiplexer 705.
The service discovery manager 710 provides information necessary to select an SP that provides a service. Upon reception of a channel selection signal from the service manager 713, the service discovery manager 710 detects a service based on the channel selection signal.
The service control manager 709 takes charge of selection and control services. For example, if a user selects a live broadcasting service, such as a conventional broadcasting service, the service control manager selects and controls the service using Internet group management protocol (IGMP) or real-time streaming protocol (RTSP). If the user selects video on demand (VoD), the service control manager 709 selects and controls the service using RTSP. RTSP supports trick mode for real-time streaming. Further, the service control manager 709 may initialize and manage a session through an IP Multimedia Control (IMC) gateway using IP multimedia subsystem (IMS) and session initiation protocol (SIP). The protocols are only exemplary and thus other protocols are also applicable.
The metadata manager 712 manages metadata related to services and stores the metadata in the SI & metadata DB 711.
The SI & metadata DB 711 stores the SI decoded by the PSI & (PSIP and/or SI) decoder 704, the metadata managed by the metadata manager 712, and the information required to select an SP, received from the service discovery manager 710. The SI & metadata DB 711 may store system setup data.
The SI & metadata DB 711 may be constructed in a non-volatile RAM (NVRAM) or a flash memory.
An IMS gateway (IG) 750 is a gateway equipped with functions needed to access IMS-based IPTV services.

The tuner 110 tunes a radio frequency (RF) broadcast signal corresponding to a channel selected by a user or pre-stored all channels among a plurality of RF broadcast signals received through an antenna and converts the tuned RF broadcast signal into an intermediate frequency (IF) signal or a baseband video or audio signal.
For example, when the tuned RF broadcast signal is a digital broadcast signal, the tuner 110 converts the tuned RF broadcast signal into a digital IF signal DIF. On the other hand, when the tuned RF broadcast signal is an analog broadcast signal, the tuner 110, the tuner 110 converts the RF broadcast signal into an analog baseband video or audio signal CVBS/SIF. That is, the tuner 110 can process all digital broadcast signals or analog broadcast signals. The analog baseband video or audio signal CVBS/SIF may be directly input to the controller 170.
The tuner 110 may be capable of receiving RF broadcast signals from an advanced television systems committee (ATSC) single-carrier system or from a digital video broadcasting (DVB) multi-carrier system.
The tuner 110 may sequentially tune a number of RF broadcast signals corresponding to all broadcast channels previously stored by a channel storage function from a plurality of RF signals received through the antenna and may convert the tuned RF broadcast signals into IF signals or baseband video or audio signals.
The demodulator 120 receives the digital IF signal DIF from the tuner 110 and demodulates the digital IF signal DIF.
For example, if the digital IF signal DIF is an ATSC signal, the demodulator 120 may perform 8-vestigal sideband (VSB) demodulation on the digital IF signal DIF. The demodulator 120 may also perform channel decoding. For channel decoding, the demodulator 120 may include a trellis decoder (not shown), a de-interleaver (not shown) and a reed-solomon decoder (not shown) so as to perform trellis decoding, de-interleaving and reed-solomon decoding.
For example, if the digital IF signal DIF is a DVB signal, the demodulator 120 performs coded orthogonal frequency division multiple access (COFDMA) demodulation upon the digital IF signal DIF. The demodulator 120 may also perform channel decoding. For channel decoding, the demodulator 120 may include a convolution decoder (not shown), a de-interleaver (not shown), and a reed-solomon decoder (not shown) so as to perform convolution decoding, de-interleaving, and reed-solomon decoding.
The demodulator 120 may perform demodulation and channel decoding on the digital IF signal DIF, thereby obtaining a transport stream (TS). The TS may be a signal in which a video signal, an audio signal and a data signal are multiplexed. For example, the TS may be an MPEG-2 TS in which an MPEG-2 video signal and a dolby AC-3 audio signal are multiplexed. An MPEG-2 TS may include a 4-byte header and a 184-byte payload.
The demodulator 120 may be configured as separate demodulators according to an ATSC method and a DVB method. That is, the demodulator 120 may include an ATSC demodulator and a DVB demodulator.
The TS output from the demodulator 120 may be input to the controller 170 and thus subjected to demultiplexing and A/V signal processing. The processed video and audio signals are output to the display 180 and the audio output unit 185, respectively.
The external device interface 135 may serve as an interface between an external device and the network TV 100. For interfacing, the external device interface 135 may include an A/V input/output (I/O) unit (not shown) or a wireless communication module (not shown).
The external device interface 135 may be connected to an external device such as a digital versatile disc (DVD) player, a Blu-ray player, a game console, a camera, a camcorder, or a computer (e.g., a laptop computer), wirelessly or by wire. Then, the external device interface 135 externally receives video, audio, or data signals from the external device and transmits the received input signals to the controller 170 of the network TV 100. In addition, the external device interface 135 may output video, audio, and data signals processed by the controller 170 to the external device. In order to receive or transmit audio, video and data signals from or to the external device, the external device interface 135 includes the A/V I/O unit (not shown) or the wireless communication module (not shown).
The A/V I/O unit may include a universal serial bus (USB) port, a composite video banking sync (CVBS) port, a component port, a super-video (S-video) (analog) port, a digital visual interface (DVI) port, a high-definition multimedia interface (HDMI) port, a red-green-blue (RGB) port, and a D-sub port, in order to input the video and audio signals of the external device to the network TV 100.
The wireless communication module may perform short-range wireless communication with other electronic devices. For short-range wireless communication, the wireless communication module may use Bluetooth, radio-frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, and digital living network alliance (DLNA) communication standards.
The external device interface 135 may be connected to various set-top boxes through at least one of the above-described ports and may thus perform an I/O operation with the various set-top boxes.
The external device interface 135 may receive applications or an application list from an adjacent external device and provide the applications or the application list to the controller 170 or the memory 140.
The network interface 130 serves as an interface between the network TV 100 and a wired/wireless network such as the Internet. The network interface 130 may include an Ethernet port for connection to a wired network. For connection to wireless networks, the network interface 130 may use wireless local area network (WLAN) (i.e., Wi-Fi), wireless broadband (WiBro), world interoperability for microwave access (WiMax), and high speed downlink packet access (HSDPA).
The network interface 130 may transmit data to or receive data from another user or electronic device over a connected network or another network linked to the connected network. Especially, the network interface 130 may transmit data stored in the network TV 100 to a user or electronic device selected from among users or electronic devices pre-registered with the network TV 100.
The network interface 130 may access a specific web page over a connected network or another network linked to the connected network. That is, the network interface 130 may access a specific web page over a network and transmit or receive data to or from a server. Additionally, the network interface 130 may receive content or data from a CP or an NP. Specifically, the network interface 130 may receive content such as movies, advertisements, games, VoD, and broadcast signals, and information related to the content from a CP or an NP. Also, the network interface 130 may receive update information about firmware from the NP and update the firmware. The network interface 130 may transmit data over the Internet or to the CP or the NP.
The network interface 130 may selectively receive a desired application among open applications over a network.
The memory 140 may store various programs necessary for the controller 170 to process and control signals, and may also store processed video, audio and data signals.
The memory 140 may temporarily store a video, audio or data signal received from the external device interface 135 or the network interface 130. The memory 140 may store information about broadcast channels by the channel storage function.
The memory 140 may store applications or a list of applications received from the external device interface 135 or the network interface 130.
The memory 140 may store a variety of platforms which will be described later.
The memory 140 may include, for example, at least one of a flash memory-type storage medium, a hard disk-type storage medium, a multimedia card micro-type storage medium, a card-type memory (e.g. a secure digital (SD) or extreme digital (XD) memory), a random access memory (RAM), or a read-only memory (ROM) such as an electrically erasable and programmable read only memory (EEPROM). The network TV 100 may reproduce content stored in the memory 140 (e.g. video files, still image files, music files, text files, and application files) to the user.
While the memory 140 is shown in
The user input interface 150 transmits a signal received from the user to the controller 170 or transmits a signal received from the controller 170 to the user.
For example, the user input interface 150 may receive control signals such as a power-on/off signal, a channel selection signal, and a screen setting signal from a remote controller 200 or may transmit a control signal received from the controller 170 to the remote controller 200, according to various communication schemes, for example, RF communication and IR communication.
For example, the user input interface 150 may provide the controller 170 with control signals received from local keys (not shown), such as inputs of a power key, a channel key, and a volume key, and setting values.
Also, the user input interface 150 may transmit a control signal received from a sensor unit (not shown) for sensing a user gesture to the controller 170 or transmit a signal received from the controller 170 to the sensor unit. The sensor unit may include a touch sensor, a voice sensor, a position sensor, a motion sensor, etc.
The controller 170 may demultiplex the TS received from the tuner 110, the demodulator 120, or the external device interface 135 into a number of signals and process the demultiplexed signals into audio and video data.
The video signal processed by the controller 170 may be displayed as an image on the display 180. The video signal processed by the controller 170 may also be transmitted to an external output device through the external device interface 135.
The audio signal processed by the controller 170 may be audibly output through the audio output unit 185. Also, the audio signal processed by the controller 170 may be transmitted to the external output device through the external device interface 135.
While not shown in
In addition, the controller 170 may provide overall control to the network TV 100. For example, the controller 170 may control the tuner 110 to tune to an RF broadcast signal corresponding to a user-selected channel or a pre-stored channel.
The controller 170 may control the network TV 100 according to a user command received through the user input interface 150 or according to an internal program. Especially the controller 170 may access a network and download an application or application list selected by the user to the network TV 100 over the network.
For example, the controller 170 controls the tuner 110 to receive a signal of a channel selected according to a specific channel selection command received through the user input interface 150 and processes a video, audio or data signal of the selected channel. The controller 170 outputs the processed video or audio signal along with information about the user-selected channel to the display 180 or the audio output unit 185.
As another example, the controller 170 outputs a video or audio signal received from an external device such as a camera or a camcorder through the external device interface 135 to the display 180 or the audio output unit 185 according to an external device video playback command received through the external device interface 150.
The controller 170 may control the display 180 to display images. For instance, the controller 170 may control the display 180 to display a broadcast image received from the tuner 110, an externally input image received through the external device interface 135, an image received through the network interface 130, or an image stored in the memory 140. The image displayed on the display 180 may be a two-dimensional (2D) or three-dimensional (3D) still image or moving picture.
The controller 170 may control content playback. The content may include any content stored in the network TV 100, received broadcast content, and externally input content. The content includes at least one of a broadcast image, an externally input image, an audio file, a still image, a web page, or a text file.
With regard to an embodiment of the present invention, the controller 170 may control display of a home image on the display 180 according to a motion input of the home image.
The home image may include a plurality of card objects that are sorted according to a content source. The card objects may include at least one of a card object indicating a thumbnail list of broadcast channels, a card object indicating a broadcast guide list, a card object indicating a broadcast reservation list or a recording list, and a card object indicating a media list in the network TV or a device connected to the network TV. In addition, the card objects may further include at least one of a card object indicating a list of connected external devices and a card object indicating a list related to call.
In addition, the home image may further include an application menu including at least one executable application item.
When a motion input of a card object is present, the controller 170 may control movement and display of the corresponding card object or control movement and display of a card object, which is not displayed on the display 180, on the display 180.
When a predetermined card object is selected among the plural card objects in the home image, the controller 170 may control display of an image corresponding card object on the display 180.
The controller 170 may control display of a received broadcast image and an object indicating information related to the broadcast image, in a card object indicating the broadcast image. In addition, a size of the broadcast image may be fixed by lock setting.
The controller 170 may control display of a set-up object for at least one of image setting, audio setting, image setting, reservation setting, pointer setting of a remote controller, and a network setting in the network TV, in the home image.
The controller 170 may control display of an object regarding log-in, help or exit item, in a region of the home image.
The controller 170 may control display of an object indicating a total number of card objects or the number of card objects displayed on the display 180 among all card objects.
When a card object title in a predetermined object is selected among card objects displayed on the display 180, the controller 170 may control display of the corresponding card object as a full image on the display 180.
When the controller 170 receives incoming call in a connected external device or a network TV, the controller 170 may control focus and display of call-related card object or control movement of the call-related card object into the display 180 and display thereof, among the plural card objects.
In case of entrance to an application view item, the controller 170 may control display an application list or application downloadable from the network TV 100 or an external network.
The controller 170 may control installment and driving of application downloaded from the external network in addition to various user interfaces. In addition, the controller 170 may control display of an image related to executed application on the display 180 according to user selection.
Although not illustrated in drawings, the network TV 100 may further include a channel browsing processor for generating a thumbnail image corresponding to a channel signal or an external input signal.
The channel browsing processor may receive the TS output from the demodulator 120 or the TS output from the external device interface 135, extract images from the received TS, and generate thumbnail images. The generated thumbnail image may be directly output to the controller 170 or may be output after being encoded. Also, it is possible to encode the thumbnail images into a stream and output the stream to the controller 170. The controller 170 may display a thumbnail list including a plurality of received thumbnail images on the display 180. The thumbnail images in the thumbnail list may be updated sequentially or simultaneously. Therefore, the user can readily identify broadcast programs received through a plurality of channels.
The display 180 converts each of an image signal, a data signal, and an OSD signal, processed by the controller 170, or each of an image signal and a data signal, received from the external device interface 135 into R, G, B signals, thereby generating driving signals.
The display 180 may be a plasma display panel (PDP), a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, a flexible display, a 3D display, or the like.
The display 180 may also be a touchscreen that can be used not only as an output device but also as an input device.
The audio output unit 185 receives a signal that is speech-processed by the controller 170, for example, a stereo signal, a 3.1 channel signal, or a 5.1 channel signal to output a sound. The audio output unit 185 may employ various speaker configurations.
To sense a user gesture, the network TV 100 may further include a sensor unit (not shown) including at least one of a touch sensor, a voice sensor, a position sensor, and a motion sensor, as described above. A signal sensed by the sensor unit (not shown) may be output to the controller 170 through the user input interface 150.
The network TV 100 may further include a camera unit (not shown) for capturing images of a user. Image information captured by the camera unit (not shown) may be input to the controller 170.
The controller 170 may detect a user gesture from an image captured by the camera unit or a signal sensed by the sensor unit (not shown) or by combining the captured image and the sensed signal.
The power supply 190 may supply corresponding power across the network TV 100.
Particularly, the power supply 190 may supply power to the controller 170 which may be implemented as a system on chip (SOC), the display 180 for displaying an image, and the audio output unit 185 for audio output.
To this end, the power supply 190 may include a rectifier (not shown) for converting alternating current (AC) into direct current (DC). If the display 180 is configured with, for example, a liquid crystal panel having a plurality of backlight lamps, the power supply 190 may further include an inverter (not shown) capable of performing pulse width modulation (PWM) for luminance change or dimming driving.
The remote controller 200 transmits user input to the user input interface 150. For transmission of user input, the remote controller 200 may use various communication techniques such as Bluetooth, RF communication, IR communication, ultra wideband (UWB), and ZigBee.
In addition, the remote controller 200 may receive a video signal, an audio signal or a data signal from the user input interface 150 and output the received signals visually, audibly or as vibrations.
The above-described network TV 100 may be a fixed digital broadcast receiver capable of receiving at least one of ATSC (8-VSB) broadcast programs, DVB-T (COFDM) broadcast programs, and ISDB-T (BST-OFDM) broadcast programs.

Other examples of the network TV 100 include a set-top box, a DVD player, a blu-ray player, a game console, a computer, etc., without the display 180 and the audio output unit 185 shown in
Referring to
The set-top box 250 may include a network interface 255, a memory 258, a signal processor 260, a user input interface 263, and an external device interface 265.
The network interface 255 serves as an interface between the set-top box 250 and a wired/wireless network such as the Internet. The network interface 255 may transmit data to or receive data from another user or another electronic device over a connected network or over another network linked to the connected network.
The memory 258 may store programs necessary for the signal processor 260 to process and control signals and temporarily store a video, audio, or data signal received from the external device interface 265 or the network interface 255. In addition, the memory 258 may store platform illustrated in
The signal processor 260 processes an input signal. For example, the signal processor 260 may demultiplex or decode an input video or audio signal. For signal processing, the signal processor 260 may include a video decoder or an audio decoder. The processed video or audio signal may be transmitted to the display device 300 through the external device interface 265.
The user input interface 263 transmits a signal received from the user to the signal processor 260 or a signal received from the signal processor 260 to the user. For example, the user input interface 263 may receive various control signals such as a power on/off signal, an operation input signal, and a setting input signal through a local key (not shown) or the remote controller 200 and output the control signals to the signal processor 260.
The external device interface 265 serves as an interface between the set-top box 250 and an external device that is connected wirelessly or by wire, particularly the display device 300, for data transmission or reception. The external device interface 265 may also interface with an external device such as a game console, a camera, a camcorder, and a computer (e.g. a laptop computer), for data transmission or reception.
The set-top box 250 may further include a media input unit for media playback. The media input unit may be a Blu-ray input unit (not shown), for example. That is, the set-top box 250 may include a Blu-ray player. After signal processing such as demultiplexing or decoding in the signal processor 260, a media signal from a Blu-ray disc may be transmitted to the display device 300 through the external device interface 265 so as to be displayed on the display device 300.

The tuner 270, the demodulator 275, the memory 278, the controller 280, the user input interface 283, the display 290 and the audio output unit 295 are identical respectively to the tuner 110, the demodulator 120, the memory 140, the controller 170, the user input interface 150, the display 180, and the audio output unit 185 illustrated in
The external device interface 273 serves as an interface between the display device 300 and a wireless or wired external device, particularly the set-top box 250, for data transmission or reception.
Hence, a video signal or an audio signal received through the set-top box 250 is output through the display 290 or through the audio output unit 295 under control of the controller 280.
Referring to
The signal processor 260 may process a broadcast signal received through the tuner 270 and the demodulator 275. The user input interface 263 may receive a channel selection input, a channel store input, etc.
As shown in
The network TV 100 may receive a broadcast signal including a video signal from the broadcast station 210. The network TV 100 may process the audio and video signals of the broadcast signal or the data signal of the broadcast signal, suitably for output from the network TV 100. The network TV 100 may output video or audio based on the processed video or audio signal.
Meanwhile, the network TV 100 may communicate with the network server 220. The network server 200 is capable of transmitting signals to and receiving signals from the network TV 100 over a network. For example, the network server 220 may be a portable terminal that can be connected to the network TV 100 through a wired or wireless base station. In addition, the network server 200 may provide content to the network TV 100 over the Internet. A CP may provide content to the network TV 100 through the network server.
The network TV 100 may communicate with the external device 230. The external device 230 can transmit and receive signals directly to and from the network TV 100 wirelessly or by wire. For instance, the external device 230 may be a media storage or a player. That is, the external device 230 may be any of a camera, a DVD player, a Blu-ray player, a PC, etc.
The broadcast station 210, the network server 220 or the external device 230 may transmit a signal including a video signal to the network TV 100. The network TV 100 may display an image based on the video signal included in the received signal. Also, the network TV 100 may transmit a signal transmitted from the network server 220 to the broadcast station 210 to the external device 230 and may transmit a signal transmitted from the external device 230 to the network TV 100 to the broadcast station 210 or the network server 220. That is, the network TV 100 may transmit content included in signals received from the broadcast station 210, the network server 220, and the external device 230 or may immediately play back the content.
The controller 170 may include a DEMUX 310, a video processor 320, an OSD generator 340, a mixer 350, a frame rate converter (FRC) 355, and a formatter 360 according to an embodiment of the present invention. The controller 170 may further include an audio processor (not shown) and a data processor (not shown).
The DEMUX 310 demultiplexes an input stream. For example, the DEMUX 310 may demultiplex an MPEG-2 TS into a video signal, an audio signal, and a data signal. The stream signal input to the DEMUX 310 may be received from the tuner 110, the demodulator 120 or the external device interface 135.
The video processor 320 may process the demultiplexed video signal. For video signal processing, the video processor 320 may include a video decoder 325 and a scaler 335.
The video decoder 325 decodes the demultiplexed video signal and the scaler 335 scales the decoded video signal so that the video signal can be displayed on the display 180.
The video decoder 325 may be provided with decoders that operate based on various standards.
If the demultiplexed video signal is, for example, an MPEG-2 encoded video signal,
the video signal may be decoded by an MPEG-2 decoder.
On the other hand, if the video signal is an H.264-encoded DMB or DVB-handheld (DVB-H) signal, the video signal may be decoded by an H.264 decoder.
The video signal decoded by the video processor 320 is provided to the mixer 350.
The OSD generator 340 generates an OSD signal autonomously or according to user input. For example, the OSD generator 340 may generate signals by which a variety of information is displayed as graphics or text on the display 180, based on control signals received from the user input interface 150. The generated OSD signal may include various data such as a UI screen, a variety of menu screens, widgets, icons, etc. of the network TV 100.
For example, the OSD generator 340 may generate a signal by which subtitles are displayed for a broadcast image or electronic program guide (EPG)-based broadcasting information.
The mixer 350 may mix the decoded video signal processed by the image processor 220 with the OSD signal generated by the OSD generator 340 and output the mixed signal to the formatter 360. As the decoded broadcast video signal or the externally input signal is mixed with the OSD signal, an OSD may be overlaid on the broadcast image or the externally input image.
The FRC 355 may change the frame rate of an input image signal. For example, a frame rate of 60 Hz is converted into a frame rate of 120 or 240 Hz. When the frame rate is to be changed from 60 Hz to 120 Hz, a first frame is inserted between the first frame and a second frame, or a predicted third frame is inserted between the first and second frames. If the frame rate is to be changed from 60 Hz to 240 Hz, three identical frames or three predicted frames are inserted between the first and second frames. It is also possible to maintain the frame rate of the input image without frame rate conversion.
The formatter 360 changes the format of the signal received from the FRC 355 to suit the display 180. For example, the formatter 360 may convert a received signal into an RGB data signal. The RGB signal may be output in the form of a Low Voltage Differential Signal (LVDS) or mini-LVDS.
The audio processor (not shown) of the controller 170 may process the demultiplexed audio signal. For audio signal processing, the audio processor (not shown) may have a plurality of decoders.
If the demultiplexed audio signal is a coded audio signal, the audio processor (not shown) of the controller 170 may decode the audio signal. For example, the demultiplexed audio signal may be decoded by an MPEG-2 decoder, an MPEG-4 decoder, an Advanced Audio Coding (AAC) decoder, or an AC-3 decoder.
The audio processor (not shown) of the controller 170 may also adjust the base, treble or volume of the audio signal.
The data processor (not shown) of the controller 170 may process the demultiplexed data signal. For example, if the demultiplexed data signal is an encoded data signal such as an electronic program guide (EPG) which includes broadcast information specifying the start time, end time, etc. of scheduled broadcast programs of each channel, the controller 170 may decode the data signal. Examples of an EPG include ATSC-Program and system information protocol (PSIP) information and DVB-Service Information (SI).
ATSC-PSIP information or DVB-SI may be included in the header of the above-described TS, i.e., a 4-byte header of an MPEG-2 TS.

A platform for either of the network TVs according to the embodiments of the present invention may have OS-based software to implement the above-described various operations.
Referring to
The legacy system platform 400 may include a stack of a driver 420, middleware 430, and an application layer 450 on the OS kernel 410.
On the other hand, the smart system platform 405 may include a stack of a library 435, a framework 440, and an application layer 455 on the OS kernel 410.
The OS kernel 410 is the core of an operating system. When the network TV is driven, the OS kernel 410 may be responsible for operation of at least one of control of hardware drivers, security protection for hardware and processors in the network TV, efficient management of system resources, memory management, hardware interfacing by hardware abstraction, multi-processing, or scheduling associated with multi-processing. Meanwhile, the OS kernel 410 may further perform power management.
The hardware drivers of the OS kernel 410 may include, for example, at least one of a display driver, a Wi-Fi driver, a Bluetooth driver, a USB driver, an audio driver, a power manager, a binder driver, or a memory driver.
Alternatively or additionally, the hardware drivers of the OS kernel 410 may be drivers for hardware devices within the OS kernel 410. The hardware drivers may include a character device driver, a block device driver, and a network device driver. The block device driver may need a buffer for buffering data on a block basis, because data is transmitted on a block basis. The character device driver may not require a buffer since data is transmitted on a basic data unit basis, that is, on a character basis.
The OS kernel 410 may be implemented based on any of various OSs such as Unix (Linux), windows, etc. The OS kernel 410 may be a general-purpose open open-source kernel which can be implemented in other electronic devices.
The driver 420 is interposed between the OS kernel 410 and the middleware 430. Along with the middleware 430, the driver 420 drives devices for operation of the application layer 450. For example, the driver 420 may include a driver(s) for a microcomputer, a display module, a graphics processing unit (GPU), an FRC, a general-purpose input/output (GPIO) pin, a high-definition multimedia interface (HDMI), a system decoder (SDEC) or DEMUX, a video decoder (VDEC), an audio decoder (ADEC), a personal video recorder (PVR), or an Inter-integrated circuit (12C). These drivers operate in conjunction with the hardware drivers of the OS kernel 410.
In addition, the driver 420 may further include a driver for the remote controller 200, especially a driver of a spatial remote controller to be described below. The remote controller driver may reside in the OS kernel 410 or the middleware 430, instead of the driver 420.
The middleware 430 resides between the OS kernel 410 and the application layer 450. The middleware 430 may mediate between different hardware devices or different software programs, for data transmission and reception between the hardware devices or the software programs. Therefore, the middleware 430 can provide standard interfaces, support various environments, and enable interaction between tasks conforming to heterogeneous communication protocols.
Examples of the middleware 430 in the legacy system platform 400 may include multimedia and hypermedia information coding experts group (MHEG) and advanced common application platform (ACAP) as data broadcasting-related middleware, PSIP or SI middleware as broadcasting information-related middleware, and DLNA middleware as peripheral device communication-related middleware.
The application layer 450 that runs atop the middleware 430 in the legacy system platform 400 may include, for example, UI applications associated with various menus in the network TV 100. The application layer 450 on top of the middleware 430 may allow editing and updating over a network by user selection. Through use of the application layer 450, the user may navigate a desired menu by manipulating the remote controller 210 while viewing a broadcast program.
The application layer 450 in the legacy system platform 400 may further include at least one of a TV guide application, a Bluetooth application, a reservation application, a digital video recorder (DVR) application, and a hotkey application.
In the smart system platform 405, the library 435 is positioned between the OS kernel 410 and the framework 440, forming the basis of the framework 440. For example, the library 435 may include secure socket layer (SSL) (a security-related library), webkit (a web engine-related library), c library (libc), and media framework (a media-related library) specifying, for example, a video format and an audio format. The library 435 may be written in C or C++. Also, the library 435 may be exposed to a developer through the framework 440.
The library 435 may include a runtime 437 with a core Java library and a virtual machine (VM). The runtime 437 and the library 435 form the basis of the framework 440.
The VM may be a virtual machine that enables concurrent execution of a plurality of instances, that is, multi-tasking. For each application of the application layer 455, a VM may be allocated and executed. For scheduling or interconnection between the plurality of instances, the binder driver (not shown) of the OS kernel 410 may operate.
The binder driver and the runtime 437 may connect Java applications to C-based libraries.
The library 435 and the runtime 437 may correspond to the middleware 430 of the legacy system platform.
In the smart system platform 405, the framework 440 includes programs on which applications of the application layer 455 are based. The framework 440 is compatible with any application and may allow component reuse, movement or exchange. The framework 440 may include supporting programs and programs for interconnecting different software components. For example, the framework 440 may include a resource manager, an activity manager related to activities of applications, a notification manager, and a CP for abstracting common information between applications. This framework 440 may be written in Java.
The application layer 455 on top of the framework 440 includes a variety of programs that can be executed and displayed in the network TV 100. The application layer 455 may include, for example, a core application that is a suite providing at least one solution of e-mail, short message service (SMS), calendar, map, or browser functions. The application layer 455 may be written in Java.
In the application layer 455, applications may be categorized into user-undeletable applications 465 stored in the network TV 100 or user-deletable applications 475 that are downloaded from an external device or a network and stored in the network TV.
Using the applications of the application layer 455, a variety of functions such as an Internet telephony service, VoD service, web album service, social networking service (SNS), location-based service (LBS), map service, web browsing service, and application search service may be performed through network access. In addition, other functions such as gaming and schedule management may be performed by the applications.

When the memory controller 1910 receives a third command for listing at least one or more bookmarked items through the user interface 1911, the memory controller 1910 accesses the bookmarking memory 1909.
In addition, the display 1906 is designed to display a first item having a first rating and a second item having a second rating separately from each other according to a rating for each respective item stored in the bookmarking memory 1909, which will be described in more detail with reference to
That is, according to a conventional method, a web site can be readily found by bookmarking only a web site in a PC. However, this method is not effective in a network TV in which various contents and items are present. Thus, the present disclosure proposes a method of rapidly accessing and re-consuming a variety of types of items by designing a network TV as illustrated in
In particular, according to an embodiment of the present invention, an item subjected to bookmarking is not limited to a web site and thus may be, for example, application, a broadcast channel, an external input source, a web site, and so on.
The external input source may be, for example, AV1, AV2, a component, or HDMI. In addition, functions (e.g., setting and channel list) related to unique functions of a TV may also be the aforementioned item. In addition, content stored in a USB media or BBTV content provided by a CP may be the aforementioned item.
As described above, an embodiment of the present invention is advantageous in terms of random setting of a rating according to user preference as well as a simple bookmarking process. For example, as illustrated in
As illustrated in
In consideration of a case in which a user of a network TV uses the aforementioned item and reuses the same item in the future, the network TV is designed to apply a bookmarking rating according to reuse possibility. A rating level may preset to a third rating, a fifth rating, a seventh rating, a seventh rating, a tenth rating, etc. by the user or use other default values.
Bookmarked items are displayed in an optimized form to the user. For example, an item that acquires a high level rating is displayed at a higher portion compared with an item that acquires a low level rating. That is, conventionally, when there are three items set to Rating 1, Rating 2, Rating 3, Rating 4, and Rating 5, 15 items may be displayed in one image. However, the network TV is designed to sequentially display items from an item having highest priority so as to improve accessibility to an item considered to be important by the user.
When a user determines whether a currently executed item is bookmarked and sets a rating using an OSD shown in
In addition, external AV input 1 is set to Rating 2, Setting is set to Rating 1, external HDMI input is set to Rating 3, and game application is set to Rating 3.
Compared with
In addition, an item “ch 7” and an item “HDMI” having Rating 3 of lowest priority, and an item “Game” are positioned in a lowest portion of the mapping table. In addition, a network TV is designed to generate an OSD as illustrated in
As illustrated in
The network TV 2400 sets a size of each icon 2420 corresponding to items having a rating of second priority to a second size according to a rating for each respective item stored in the bookmarking memory.
In addition, the network TV 2400 sets a size of each icon 2440 corresponding to items having a rating of third priority to a third size according to a rating for each respective item stored in the bookmarking memory. As illustrated in
Thus, the network TV 2400 may be designed such that items having a rating of high priority occupy regions having relatively high selectivity and visibility, and thus, a user can stereoscopically use bookmarked items.
As illustrated in
The network TV 2500 displays a title and description of each icon corresponding to items having a rating of second priority in a second region 2520 according to a rating for each respective item stored in the bookmarking memory.
That is, with regard to items having a high rating, related short description thereof as well as a title thereof may be provided so as to ensure relatively high selectivity and visibility of items having a high rating. However, only a title is provided with regard to items with a low rating. In addition, according to an embodiment of the present invention, although not illustrated in
As illustrated in
Thus, a user may rapidly select an item preferred by the user simply by comparing dimensions instead of checking icons of numerous bookmarked items.
As illustrated in
Thus, a user may rapidly select an item preferred by the user simply by comparing contrast ratios instead of checking icons of numerous bookmarked items.
As illustrated in
In addition, the network TV 2800 displays each icon 2820 corresponding to items having Rating 2 with an intermediate size. The network TV 2800 displays each icon 2830 corresponding to items having Rating 3 with a smallest size.
The network TV 2800 is designed to have different methods of displaying items corresponding to Ratings 1 through 3 and an item corresponding to Rating 4. That is, items corresponding to Rating 4 are output in the form of text instead of in the form of icon. As illustrated in
Thus, the selectivity and visibility of items having relatively high ratings (e.g., Ratings 1 through 3) may be increased, and an item (e.g., Rating 4) having a relatively low rating may be displayed in the text form. Thus, as many as possible bookmarking items can be displayed at one time.
Thus far, the method of displaying items having all ratings in one screen has been described with reference to
Thus, as illustrated in
The network TV 2900 is designed to display a first tab 2910 formed by collecting items having a rating with first priority, a second tab 2920 formed by collecting items having a rating with second priority, a third tab 2930 formed by collecting items having ratings with third priority, and a fourth tab 2940 formed by collecting items having ratings with fourth priority.
In addition, when a specific tab, that is, the second tab 2930 is selected among the displayed tabs, the network TV 2900 displays icons corresponding to items belonging to the selected specific tab.
As illustrated in
As illustrated in
That is, comparing
In addition,
According to an embodiment of the present invention, a network TV for bookmarking at least one or more item receives a first command for setting bookmarking of a currently executed item and a second command for selecting a rating of the bookmarked item (S3110).
The network TV stores information for identification of the bookmarked item having the selected rating in a bookmarking memory according to the received first command and second command (S3120) and receives a third command for listing at least one or more bookmarked items (S3130).
In addition, the network TV accesses the bookmarking memory (S3140) and displays a first item having a first rating and a second item having a second rating separately from each other according to a rating for each respective item stored in the bookmarking memory (S3150).
Furthermore, although not illustrated in
According to another embodiment of the present invention, a step S3150 includes setting a size of each icon corresponding to items having a rating of first priority to a first size according to a rating for each respective item stored in the bookmarking memory, setting a size of each icon corresponding to items having a rating of second priority to a second size according to a rating for each respective item stored in the bookmarking memory (where the size is smaller than the first size), and displaying icons of the set first size and icons of the set second size, which would be understood in more detail by one of ordinary skill in the art with reference to
According to another embodiment of the present invention, a step S3150 includes displaying a title and description of each icon corresponding to items having a rating of first priority according to a rating for each respective item stored in the bookmarking memory, and displaying a title and description of each icon corresponding to items having a rating of second priority according to a rating for each respective item stored in the bookmarking memory, which would be understood in more detail by one of ordinary skill in the art with reference to
According to another embodiment of the present invention, a step S3150 includes displaying a first tab formed by collecting items having rating with first priority and a second tab formed by collecting items having a rating with second priority, and displaying icons corresponding to items belonging to a selected specific tab when the specific tab is selected among the displayed tabs, which would be understood in more detail by one of ordinary skill in the art with reference to
Furthermore, as described above, the item corresponds to, for example, at least one or more of application, a web site, a broadcast channel, or an external input source.
As illustrated in
Furthermore, when an option for selection of bookmarking is clicked on in the message 3220, a message 3230 for adjusting a bookmarking position is output. In addition, a cursor or an arrow 3240 for selection of a specific position using a mouse, a keyboard, a remote controller, etc. is displayed together.
When a position of a specific item is selected to a second turn in
Thus, as illustrated in
As illustrated in
As illustrated in
As illustrated in
On the other hand, icons positioned in a second row are displayed with the same size 3450 regardless of the predetermined direction. Thus, the user may adjust sizes of icons desired by the user using both the two methods.
As illustrated in
As illustrated in
As illustrated in
Thus, the user can readily check specific icons having high priority and as many icons with relatively low priority if possible can be output in one image.
According to the aforementioned embodiments of the present invention, a bookmarking function is extended to an environment of a new device such as a network TV, thereby increasing item access speed of a consumer. In addition, a GUI that is relatively optimized to the user is designed to improve work effectiveness of bookmarking.
Hereinafter (in
First, as shown in
A remote controller 3659 may be a general remote controller or may correspond to a spatial remote controller to motion remote controller shown in
The tuner 3651 tunes a radio frequency (RF) broadcast signal corresponding to a channel selected by a user or pre-stored all channels among a plurality of RF broadcast signals received through an antenna and converts the tuned RF broadcast signal into an intermediate frequency (IF) signal or a baseband video or audio signal.
For example, when the tuned RF broadcast signal is a digital broadcast signal, the tuner 3651 converts the tuned RF broadcast signal into a digital IF (DIF) signal. On the other hand, when the tuned RF broadcast signal is an analog broadcast signal, the tuner 110, the tuner 110 converts the RF broadcast signal into an analog baseband video or audio signal CVBS/SIF. That is, the tuner 3651 can process all digital broadcast signals or analog broadcast signals. The analog baseband video or audio signal CVBS/SIF may be directly input to the controller the controller 3610.
The tuner 3651 can receive RF broadcast signals from an advanced television systems committee (ATSC) single-carrier system or from a digital video broadcasting (DVB) multi-carrier system.
The demodulator 3652 receives the digital IF signal DIF from the tuner 110 and demodulates the digital IF signal DIF. For example, if the digital IF signal DIF is an ATSC signal, the demodulator 3652 may perform 8-vestigal sideband (VSB) demodulation on the digital IF signal DIF. The demodulator 3652 may also perform channel decoding. For channel decoding, the demodulator 3652 may include a trellis decoder (not shown), a de-interleaver (not shown) and a reed-solomon decoder (not shown) so as to perform trellis decoding, de-interleaving and reed-solomon decoding.
The demodulator 3652 may perform demodulation and channel decoding on the digital IF signal DIF, thereby obtaining a transport stream (TS). The TS may be a signal in which a video signal, an audio signal and a data signal are multiplexed. For example, the TS may be an MPEG-2 TS in which an MPEG-2 video signal and a dolby AC-3 audio signal are multiplexed. An MPEG-2 TS may include a 4-byte header and a 184-byte payload.
The TS output from the demodulator 3652 may be input to the controller 3610 and thus subjected to demultiplexing and A/V signal processing. The processed video and audio signals are output to the display 3654 and the speaker 3655, respectively. In more detail, a demultiplexer 3611 demultiplexes the multiplexed video data and audio data, transmits the video data to a video signal processor 3612, and transmits the audio data to an audio signal processor 3614. The video signal processor 3612 converts a video data format that can be output from the display 3654. The audio signal processor 3614 converts an audio data format that can be output from the speaker 3655.
A mixer 3613 mixes the video data transmitted from the video signal processor 3612 and video data related to the OSD generated by an OSD generator 3615.
The external device interface 3657 is a module that is designed to transmit data between an external device and a TV. To this end, the external device interface 3657 may include an A/V I/O unit (not shown) or a wireless communication module (not shown).
The external device interface 3657 may be connected to an external device such as a digital versatile disc (DVD) player, a Blu-ray player, a game console, a camera, a camcorder, or a computer (e.g., a laptop computer), wirelessly or by wire. Then, the external device interface 3657 externally receives video, audio, or data signals from the external device and transmits the received input signals to the controller 3610 of the network TV. In addition, the external device interface 3657 may output video, audio, or data signals processed by the controller 3610 to the external device.
The A/V I/O unit may include a universal serial bus (USB) port, a composite video banking sync (CVBS) port, a component port, a super-video (S-video) (analog) port, a digital visual interface (DVI) port, a high-definition multimedia interface (HDMI) port, a red-green-blue (RGB) port, and a D-sub port, in order to input the video and audio signals of the external device to the network TV.
The wireless communication module may perform short-range wireless communication with other electronic devices. The wireless communication module may be connected to other electronic devices over the network using Bluetooth, radio-frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, and digital living network alliance (DLNA) communication standards.
The external device interface 3657 may receive applications or an application list from an adjacent external device and provide the applications or the application list to the controller 3610 or the memory 3653.
The network interface 3656 serves as an interface between the network TV and a wired/wireless network such as the Internet. The network interface 3656 may include an Ethernet port for connection to a wired network. For connection to wireless networks, the network interface 3656 may use wireless local area network (WLAN) (i.e., Wi-Fi), wireless broadband (WiBro), world interoperability for microwave access (WiMax), and high speed downlink packet access (HSDPA).
The network interface 3656 may access a specific web page over a connected network or another network linked to the connected network. That is, the network interface 3656 may access a specific web page over a network and transmit or receive data to or from a server. Additionally, the network interface 3656 may receive content or data from a CP or an NP. Specifically, the network interface 3656 may receive content such as movies, advertisements, games, VoD, and broadcast signals, and information related to the content from a CP or an NP over the network. Also, the network interface 3656 may selectively receive a desired application among open applications over a network.
The memory 3653 may store various programs necessary for the controller 3610 to process and control signals, and may also store processed video, audio and data signals. In addition, the memory 3653 may temporarily store a video, audio or data signal received from the external device interface 3657 or the network interface 3656. The memory 3653 may store information about broadcast channels by the channel storage function. Lastly, the memory 3653 may store applications or a list of applications received from the external device interface 3657 or the network interface 3656.
The user interface 3658 transmits a signal received from the user to the controller 3610. For example, the user interface 3658 may receive control signals such as a power-on/off signal, a channel selection signal, and a screen setting signal from a remote controller 3659 may transmit a control signal received from the controller 3610 to the remote controller 3659, according to various communication schemes, for example, RF communication and IR communication.
In particular, functions of the user recognition sensor 3660, the monitoring module 3661, the calculator 3662, the OSD generator 3615, the memory 3653, and so on illustrated in
The OSD generator 3615 generates a first OSD for listing at least one or more items. The items may correspond to a random content and may be, for example, application that is received from the network interface 3656 or the external device interface 3657 and stored in the memory 3653.
The display 3654 displays the generated first OSD on a screen of the network TV. In this case, a size of an image corresponding to the at least one item is assumed to be R.
The monitoring module 3661 is designed to monitor a usage history of the at least one item. The memory 3653 stores the monitoring result. According to necessity of one of ordinary skill in the art, the memory 3653 may be designed to permanently store data or designed using a flash memory that temporally stores data. A database of the memory 3653 that stores the monitoring result will be described in more detail with reference to
The calculator 3662 converts a size of an image corresponding to the at least one or more items to R′ from R according to the monitoring result stored in the memory 3653. A process of converting the size of the image corresponding to the item to R′ from R by the calculator 3662 will be described in more detail with reference to
When the OSD generator 3615 receives a command for outputting a list of pre-stored items using the remote controller 3659 or the user interface 3658, the OSD generator 3615 generates a second OSD for listing at least one or more items.
The display 3654 is designed to display the generated second OSD on the screen and a size of an image corresponding to the at least one or more items is R′. A process of displaying the aforementioned first OSD and second OSD via the display 3654 will be described in more detail with reference to
When the aforementioned network TV according to the second embodiment of the present invention is used, for example, application preferred by a user and non-preferred application can be readily identified, and in particular, user preference can be reflected in real time over time.
In addition, the monitoring module 3661 is designed to monitor, for example, at least one or more of first data regarding the number of times of access to each item, second data regarding total period of time for execution of each item, and third data regarding a period of time from a point of time for downloading each item.
Furthermore, for example, the calculator 3662 is designed to increase R′ in proportion to the first data and the second data and to increase R′ in inverse proportion to the third data.
The aforementioned embodiment corresponds to a case in which an item size on an OSD is changed according to a usage history of an item. A method of providing different OSDs for respective users of a network TV using the user recognition sensor 3660 will be described below.
The user recognition sensor 3660 is embodied according to the second embodiment of the present invention. For example, the user recognition sensor 3660 may be designed using an iris scan sensor, a finger scan sensor, a multiple camera solution, an ID/PW input method, and so on.
The aforementioned multiple camera solution is a method using a 2D camera and a 3D camera and is advantageous in that a user does not have to do any particular action. For example, the network TV is designed to recognize a user using the network TV using the 2D camera and to identify the recognized user using the 3D camera. In addition, a monitoring result of a first identified user is stored in a first address of the memory 3653 and a monitoring result of a second identified user is stored in a second address of the memory 3653. Thus, the network TV is advantageous in that structures of item lists are different for respective users. The multiple camera solution will be described in more detail with reference to
In addition, the ID/PW input method will be described in more detail with reference to
When power of the network TV 3700 according to the second embodiment of the present invention is switched to an on-state from a standby state, an initial image 3710 is displayed. The initial image 3710 corresponds to, for example, broadcast data received from a tuner, application received from a network interface, video data received from an external device interface, or the like.
In this case, the network TV 3700 is designed to output a guide message for identification of users. The guide message may include both an ID item 3720 and a passport 3730, as illustrated in
Thus, when pre-set information is input to the ID item 3720 and the passport 3730, a current user of the network TV 3700 may be readily identified and only a usage history of items of the current user may be separately managed. However, when the network TV 3700 is designed in such a way, the user should input an ID and a passport. Thus, a solution that does not need any particular user action will be described with reference to
In general, first image sensors related to depth data processing has an aspect that is not appropriate for long-distance facial recognition due to problems in terms of limited resolution (e.g., a maximum of VGA resolution) and a recognition distance (e.g., 3.5 m). In addition, second image sensors related to color data processing has low recognition speed and an aspect that is not robust to a light condition. Thus, in order to remedy these defects of each image sensor, a multimedia device according to an embodiment of the present invention is designed in conjunction with an image sensor module in the hybrid form obtained by a first image sensor and a second image sensor.
The aforementioned first image sensor may be, for example, an infrared (IR) camera or a depth camera. In more detail, the IR camera or the depth camera uses a time of flight (TOF) method and a structured light method. According to the TOF method, distance information is calculated using a time difference between infrared irradiation and return. According to the structured light method, a distance is calculated by irradiating infrared rays and analyzing modified patterns. However, the first image sensor has advantages in terms of depth data recognition and processing speed and can readily sense an object, human, and so on in a dark environment. However, the first image sensor has disadvantages of reducing resolution at a long distance.
Furthermore, the aforementioned second image sensor may be, for example, a color camera or an RGB camera. In more detail, for example, the color camera or the RGB camera uses a stereo camera method and a mono camera method. According to the stereo camera method, a hand, a face, and so on is detected and tracked based on image parallax comparison information between images captured by two cameras. According to the mono camera method, a hand, a face, and so on is detected and tracked based on shape and color information acquired via photography using one camera. However, the second image sensor has advantages in terms of improved resolution compared with the first image sensor and is vulnerable to surrounding lighting and performs recognition with difficulty. In particular, it is difficult to accurately recognize a depth.
To overcome such problems, as illustrated in
When photography and data analysis of the first image sensor are completed, the second image sensor captures an image of a user face, as illustrated in
Among a plurality of heterogeneous image sensors according to an embodiment of the present invention, the first image sensor captures a first image of an object positioned around the network TV and extracts depth data from the captured first image. The network TV may be designed in such a way that regions of objects are displayed with different contrasts according to a distance, as illustrated in (1) of
Furthermore, the first image sensor may recognize and cognize at least one user face using the extracted depth data. That is, user body information (e.g., a face, a hand, a foot, a joint, etc.) is extracted as illustrated in (2) of
In addition, among a plurality of heterogeneous image sensors according to an embodiment of the present invention, the second image sensor captures a second image of the cognized user face, which is illustrated in (5) of
When the first and second image sensors illustrated in
When photography and analysis of the first image sensor and the second image sensor are completed, the network TV according to the second embodiment of the present invention accesses a memory that stores data corresponding to the extracted feature information and extracts information for identification of a specific user, stored in the memory.
As described above, the network TV according to the second embodiment of the present invention is designed in such a way that the first image sensor detects user position information or face coordinate information and the second image sensor recognizes a face using data acquired by the first image sensor.
Furthermore, the network TV is designed in such a way that the second image sensor is not unconditionally used and operates only in a specific condition. For example, when information regarding a distance from a user, acquired via an operation of the first image sensor, is equal to or less than a first reference value or a recognition rate with respect to the user face acquired via the operation of the first image sensor is more than or equal to a second reference value, only the first image sensor detects and identifies a user face positioned around the network TV. On the other hand, when the information regarding the distance from the user, acquired via an operation of the first image sensor, exceeds the first reference value or the recognition rate with respect to the user face acquired via the operation of the first image sensor is less than the second reference value, the user face is recognized using the second image sensor in addition to the first image sensor.
Thus, when a plurality of heterogeneous image sensors of different types are used, a user positioned at a long distance from the network TV can be more accurately recognized and item usage histories for respective users can be monitored.
In
A monitoring module of the network TV counts the number of times of execution whenever a specific item is executed (or is accessed). In addition, the monitoring module stores playback time of the executed item in a memory. Thus, the database illustrated in
Although not illustrated in
In addition, as illustrated in
Repeated description of
Furthermore, data illustrated in
As illustrated in
Thus, in this case, a very old bookmarked item and a latest bookmarked item may be indicated in the same way and an item that is frequency used by a user and an item that is not frequently used by the user may be indicated without any particular difference.
Although items to which a bookmarking function is applied in
It is assumed that users of the network TV are separately identified as illustrated in
According to Equation R′=(ax+1)R illustrated in
As illustrated in
According to Equation illustrated in
It is assumed that users of the network TV are separately identified as illustrated in
According to Equation R′=(bx+cy+1)R−dt illustrated in
Unlike in
However, when a long period of time elapses, if t is unpredictably increased, risk of giving a negative value to R′ is present. Thus, in order to overcome this problem, a case in which R′ is set not to be less than a minimum value (e.g., 0.5R) belongs to the scope of the present invention.
It is assumed that an item size for each respective user is changed according to the calculation method illustrated in
When a user of the network TV 4400 according to the second embodiment of the present invention requests output of a list of pre-stored items or items of bookmarked items, a first ODS 4410 illustrated in
When a current user of the network TV 4400 is identified as the user A via the aforementioned user recognition sensor, a network TV 4401 outputs a second OSD 4411 as illustrated in
The second OSD 4411 is the same as the second OSD 4410 in term of including, for example, an item 1 4421, an item 2 4431, an item 3 4441, an item 4 4451, an item 5 4461, and an item 6 4471. However, among the aforementioned items, sizes of the items 4441, 4451, and 4461 belonging to a first group increase, sizes of the items 4431 and 4471 belonging to a second group decrease, and sizes of the item 4421 belonging to a third group is maintained.
It is assumed that an item size for each respective user is changed according to the calculation method illustrated in
When a user of the network TV 4500 according to the second embodiment of the present invention requests output of a list of pre-stored items or items of bookmarked items, a first OSD 4510 illustrated in
When a current user of the network TV 4500 is identified as the user B via the aforementioned user recognition sensor, a network TV 4501 outputs a second OSD 4511 as illustrated in
The second OSD 4511 is the same as the first OSD 4510 in terms of including, for example, an item 1 4521, an item 2 4531, an item 3 4541, an item 4 4551, an item 5 4561, and an item 6 4571. However, among the aforementioned items, sizes of the item 4571 belonging to a first group increase, sizes of the items 4521, 4531, 4551, and 4561 belonging to a second group decrease, and sizes of the item 4541 belonging to a third group is maintained.
Thus, a user that checks the second OSD 4511 illustrated in
Thus far, bookmarked items or pre-stored items have been described with reference to the above drawings. However, the present invention can be applied to an embodiment for embodying a channel browser image.
When a user inputs a command for execution of a channel browsing function, the network TV 4600 according to the second embodiment of the present invention displays a first OSD 4610 as illustrated in
In this case, the aforementioned monitoring module continuously checks tuning time of each channel and adjusts a size allocated to each channel on a channel browser image using Equation illustrated in
For example, when seven days elapses from a point of time when an image of
Comparing
Thus, a user using the network TV according to the second embodiment of the present invention can rapidly access a channel preferred by the user in a complex channel browsing image.
Thus far, bookmarked items or pre-stored items have been described with reference to the above drawings. However, the present invention can be applied to an embodiment for embodying an EPG image.
When a user inputs a command for EPG execution, the network TV 4700 according to the second embodiment of the present invention displays a first EPG image as illustrated in
In this case, the aforementioned monitoring module continuously checks watching time of each event displayed in the EPG image and adjusts a size allocated to each event in the EPG image using Equation illustrated in
For example, when about one month elapses, a network TV 4701 according to the second embodiment of the present invention displays a second EPG image as illustrated in
Accordingly, a user who uses the network TV according to the second embodiment of the present invention may experience an improved EPG image that is dynamically changed according to a watch history of the user instead of a fixed EPG image according to conventional art.
Furthermore, the embodiments of the present invention have been separately described with reference to each of the drawings.
