1. Field
One or more embodiments described herein relate to managing and displaying information on an electronic device.
2. Background
A variety of display devices are currently in use, including televisions, monitors, smart phones, music and video players, computers, PDAs, and many, many more. Many of these devices boot of one or more applications and include an operating system in order to manage the same. Often times, however, this booting process takes a considerable amount of time, which is considered undesirable by users.
The content provider 10 manufactures various contents and provides them. Examples of the content provider 10 include a terrestrial broadcaster, a cable system operator (SO), a multiple system operator (MSO), a satellite broadcaster, and an Internet broadcaster, as illustrated in
Also, the content provider 10 may provide various applications in addition to broadcast contents, which will be described in more detail later.
The service provider 20 can provide contents provided by the content provider 10 by service packaging them. For example, the service provider 20 of
In the meantime, the service provider 20 may provide a service to the client 100 by using a unicast or multicast mode. The unicast mode is to transmit data between a single transmitter and a single receiver 1:1. In case of the unicast mode, for example, if the receiver requests a server to transmit data, the server can transmit data to the receiver in accordance with the request. The multicast mode is to transmit data to a plurality of receivers of a specific group. For example, the server can transmit data to a plurality of receivers, which are previously registered therewith, at one time. For this multicast registration, IGMP (Internet Group Management Protocol) can be used.
The network provider 30 may provide a network for providing a service to the client 100. The client 100 may construct a home network end user (HNED) to receive a service.
In the system of the aforementioned display device, conditional access or content protection can be used to protect contents which are transmitted. For conditional access or content protection, a cable card or downloadable conditional access system (DCAS) can be used.
In the meantime, the client 100 may provide contents through the network. In this case, the client 100 may be a content provider contrary to the above. The content provider 10 may receive contents from the client 100. In this case, it is advantageous in that bidirectional content service or data service is available.
Application information table (AIT) data, a real-time broadcast content, application data, and stream event are received through the broadcast interface 101. The real-time broadcast content may be designated as a linear A/V content.
The section filter 102 performs section filtering for four kinds of data received through the broadcast interface 101. Then, the section filter 102 transmits AIT data to the AIT filter 103, the linear A/V content to the broadcast data processor 111, and stream event and application data to the application data processor 104.
In the meantime, a non-linear A/V content and application data are received through the Internet interface 108. The non-linear A/V content may be content on demand (COD) application, for example. The non-linear A/V content is transmitted to the media player 106, and the application data is transmitted to the runtime module 109.
Moreover, the runtime module 109, as illustrated in
The service provider may perform service provider discovery (S301), and the display device may transmit a service provider (SP) attachment request signal (S302). If SP attachment is finished, the display device receives provisioning information (S303). Moreover, the display device receives a master SI table from the service provider (S304), receives a virtual channel map table (S305), receives a virtual channel description table (S306), and receives a source table (S307).
Hereinafter, the process steps for receiving channel information will be described in more detail. The service provider discovery may mean that service providers, which provide IPTV related services, discover a service discovery (SD) server that provides information on the service providers.
For example, three methods for discovering an address list that can receive information (for example, SP discovery information) on the SD server will be provided as follows. First of all, an address previously set by the display device or an address set by a manual operation of the user can be used. Second, a DHCP based SP discovery method can be used. Third, a DNS SRV-based SP discovery method can be used. Also, the display device accesses a server of an address acquired by any one of the above three methods and receives a service provider discovery record that includes information required for service discovery per SP. Then, the display device performs a service search step by using the received service provider discovery record. The above steps can be performed in a push mode or pull mode.
The display device performs a registration procedure (or service attachment procedure) by accessing the SP attachment server designated by an SP attachment locator of the SP discovery record.
Moreover, after performing a separate authentication procedure by accessing an SP authentication service server designated by an SP authentication locator, the display device may perform a service authentication procedure.
In the meantime, after the service attachment procedure is successfully performed, data transmitted from the server to the display device may be a form of a provisioning information table.
The display device transmits the data to the service attachment server during the service attachment procedure, wherein the data includes ID and location information of the display device. The service attachment server can define a service subscribed by the display device, based on the received data. Moreover, address information that can acquire service information desired to be received by the display device is provided in the form of the provisioning information table. The address information corresponds to access information of the master SI table. In this case, it is easy to provide a customized service per subscriber.
The service information includes a master SI table record that manages access information and version on the virtual channel map, a virtual channel map table that provides a package type service list, a virtual channel description table that includes detailed information of each channel, and a source table that includes access information that enables actual access to services.
Each virtual channel map is uniquely identified by a virtual channel map identifier, and virtual channel map version represents version information of the virtual channel map. If any one of all tables connected to one another along an arrow starting from the master SI table in
For example, if there is any change of the source table, version of the source table is increased, and version of the virtual channel description table for reference of the source table is also changed. Accordingly, change of a lower table causes change of an upper table, whereby version of the master SI table is finally changed.
The master SI table may exist per service provider. However, if configuration of the service is varied per location or subscriber (or subscriber group), the service provider is designed to have a plurality of master SI tables, thereby providing a customized service per each unit. In this way, if the service provider is designed, it is possible to efficiently provide a customized service for location of a subscriber and subscription information through the master SI table.
The virtual channel map table may have one or more virtual channels, and includes location information that can acquire detailed information of the channel without including the detailed information in the virtual channel map. Virtual channel description location of the virtual channel map table indicates location of the virtual channel description table that includes detailed information of the channel.
The virtual channel description table includes detailed information of the virtual channel, and can access the virtual channel description table by using the virtual channel description location of the virtual channel map table.
The source table provides access information (for example, IP address, port, AV codec, transport protocol, etc.) per service, wherein the access information is required for actual access to the service.
The aforementioned master SI table, the virtual channel map table, the virtual channel description table, and the source table are transferred through four flows, which are logically divided from one another, in a push mode or pull mode. In the meantime, the master SI table can be transmitted in a multicast mode for version management, and monitors version change by receiving multicast streaming.
The network interface 701 receives packets from a network, and transmits the packets to the network. In other words, the network interface 701 receives services, contents, etc. from the service provider through the network.
The TCP/IP manager 702 is involved in packets received in the display device 700 and packets transmitted from the display device 700, i.e., packet transfer from the source to the destination. The TCP/IP manager 702 sorts the received packets to correspond to a proper protocol, and outputs the sorted 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 takes the role of control of received service data. For example, if the service delivery manager 703 controls real-time streaming data, it can use RTP/RTCP. If the service delivery manager 703 transmits the real-time streaming data by using RTP, it parses the received packets in accordance with RTP and transmits the parsed packets to the demultiplexer 705 or stores the parsed packets in the SI&Metadata DB 711 under the control of the service manager 713. The service delivery manager 703 feeds the received information back to a server, which provides a service, by using RTCP.
The demultiplexer 705 demultiplexes the received packets to audio, video and PSI (Program Specific Information) data and then transmits the demultiplexed 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 service information such as PSI, for example. Namely, the PSI& (PSIP and/or SI) decoder 704 receives and decodes PSI section, PSIP (Program and Service Information Protocol) section or SI (Service Information) section, which is demultiplexed by the demultiplexer 705.
Also, the PSI& (PSIP and/or SI) decoder 704 decodes the received sections to make a database for service information, and stores the database for service information in the SI&Metadata DB 711.
The audio/video decoders 706/707 decode the video data and the audio data, which are received from the demultiplexer 705. The audio data decoded by the audio decoder 706 and the video data decoded by the video decoder 707 are provided to the user through the display 708.
The UI manager 714 and the service manager 713 manage the whole state of the display device 700, provide a user interface, and manage other managers. The UI manager 714 provides a graphic user interface for the user by using an on screen display (OSD), and performs a receiving operation based on a key input from the user. For example, if a key input signal for channel selection is input from the user, the UI manager 714 transmits the key input signal to the service manager 713.
The service manager 713 controls managers related to the service, such as the service delivery manager 703, the service discovery manager 710, the service control manager 709, and the metadata manager 712.
Also, the service manager 713 makes a channel map and selects a channel by using the channel map in accordance with the key input signal received from the UI manager 714. The service manager 713 receives service information of the channel from the PSI& (PSIP and/or SI) decoder 704 and sets audio/video PID (Packet Identifier) of the selected channel in the demultiplexer 705.
The service discovery manager 710 provides information required to select the service provider that provides services. If a signal related to channel selection is received from the service manager 713, the service discovery manager 710 discovers a corresponding service by using the received information.
The service control manager 709 takes the role of selection and control of the service. For example, if the user selects a live broadcasting service like the existing broadcasting mode, the service control manager 709 uses IGMP or RTSP. If the user selects a video on demand (VOD) service, the service control manager 709 selects and controls the service by using RTSP. The RTSP protocol can provide a trick mode for real-time streaming. Also, the service control manager 709 can initiate and manage a session through IMC gate by using IMS (IP Multimedia Subsystem) and Session Initiation Protocol (SIP). The above protocols are only exemplary, and other protocols may be used depending on embodiments.
The metadata manager 712 manages metadata related to the service and stores the metadata in the SI&Metadata DB 711. The SI&Metadata DB 711 stores the service information decoded by the PSI& (PSIP and/or SI) decoder 704, the metadata managed by the metadata manager 712, and the information required to select the service provider provided by the service discovery manager 710. Also, the SI&Metadata DB 711 may store setup data for the system.
The SI&Metadata DB 711 may be implemented by using a NonVolatile RAM (NVRAM) or a flash memory, and the IG 750 is a gateway where functions required for access to IMS based IPTV services are gathered.
The tuner 110 selects one of RF (radio frequency) broadcast signals received through an antenna, which corresponds to a channel selected by the user or all previously stored channels. Also, the tuner 110 converts the selected RF broadcast signal to an intermediate frequency signal or a baseband video or audio signal.
For example, if the selected RF broadcast signal is a digital broadcast signal, the tuner 110 coverts the selected RF broadcast signal to a digital IF (DIF) signal. If the selected RF broadcast signal is an analog broadcast signal, the tuner 110 coverts the selected RF broadcast signal to an analog baseband video or audio signal (CVBS/SIF). In other words, the tuner 110 can process both the digital broadcast signal and the analog broadcast signal. The analog baseband video or audio signal (CVBS/SIF) output from the tuner 110 may directly be input to the control module 170.
Also, the tuner 110 can receive RF broadcast signal of a single carrier based on an advanced television system committee (ATSC) mode and RF broadcast signal of multiple carriers based on a digital video broadcasting mode (DVB).
In the meantime, the tuner 110 sequentially selects RF broadcast signals of all broadcast channels stored through a channel memory function from RF broadcast signals received through the antenna, and converts the selected RF broadcast signals to intermediate frequency signals or baseband video or audio signals.
The demodulation module 120 receives the digital IF (DIF) signal converted by the tuner 110 and demodulates the received digital IF signal.
For example, if the digital IF signal output from the tuner 110 is based on the ATSC mode, the demodulation module 120 performs 8-vestigal side band (8-VSB) demodulation, for example. Also, the demodulation module 120 may perform channel decoding. To this end, the demodulation module 120 may include a trellis decoder, a de-interleaver, and a Reed-Solomon decoder to perform trellis decoding, de-interleaving, and Reed-Solomon decoding.
For example, if the digital IF signal output from the tuner 110 is based on the DVB mode, the demodulation module 120 performs coded orthogonal frequency division modulation (COFDMA) demodulation, for example. Also, the demodulation module 120 may perform channel decoding. To this end, the demodulation module 120 may include a convolution decoder, a de-interleaver, and a Reed-Solomon decoder to perform convolution decoding, de-interleaving, and Reed-Solomon decoding.
The demodulation module 120 can output a stream signal (TS) after performing demodulation and channel decoding. At this time, the stream signal may be a signal where a video signal, an audio signal and a data signal are multiplexed. For example, the stream signal may be MPEG-2 Transport Stream (TS) where a video signal of an MPEG-2 specification and an audio signal of Dolby AC-3 specification are multiplexed. Specifically, the MPEG-2 TS may include a 4 byte header and 184 byte payload.
The aforementioned demodulation module 120 may be provided separately depending on the ATSC mode and the DVB mode. Namely, an ATSC demodulation module and a DVB demodulation module may be provided separately.
The stream signal output from the demodulation module 120 may be input to the control module 170. The control module 170 performs demultiplexing, video/audio signal processing, etc. and then outputs video to the display module 180 and audio to the audio output module 185.
The external device interface module 135 may connect an external device to the display device 100. To this end, the external device interface module 135 may include an A/V input/output unit (not shown) or a wireless communication unit (not shown).
The external device interface module 135 is connected to external devices such as Digital Versatile Disks (DVD), Blu-rays, game devices, cameras, camcorders, computers (e.g., notebook computers), etc. through wire/wireless cables. The external device interface module 135 transmits a video, audio, or data signal externally input through an external device connected thereto, to the control module 170 of the display device 100. Also, the external device interface module 135 outputs the video, audio or data signal processed by the control module 170 to the external device. To this end, the external device interface module 135 may include an A/V input/output unit (not shown) or a wireless communication unit (not shown).
The A/V input/output unit of the external input circuit may include a USB terminal, a composite Video Banking Sync (CVBS) terminal, a component terminal, an S-video terminal (analog), a Digital Visual Interface (DVI) terminal, a High Definition Multimedia Interface (HDMI) terminal, an RGB terminal, a D-SUB terminal, etc., to input video and audio signals of the external device to the display device 100.
The wireless communication unit may perform a short-distance wireless communication with other electronic devices. For example, communication standards such as Bluetooth, Radio Frequency Identification (RFID), infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, Digital Living Network Alliance (DLNA), etc. can be used for the short-distance wireless communication, whereby network connection between the display device 100 and other electronic devices can be performed.
In addition, the external device interface module 135 may be connected to various set-top boxes through at least one of the above-mentioned various terminals to perform input/output operation with the set-top boxes.

Although
The user input interface module 150 transmits the signal input by the user to the control module 170 or transmits the signal from the control module 170 to the user. For example, the user input interface module 150 may receive a control signal such as power on/off, channel selection and screen setup from the remote controller 200 or transmit the control signal from the control module 170 to the remote controller 200 in accordance with various communication modes such as RF communication mode and IR communication mode.

This display device includes control module 170 having a demultiplexer 310, a video processor 320, an OSD generator 340, a mixer 350, a frame rate converter 355, and a formatter 360. The control module 170 may further include an audio processor (not shown) and a data processor (not shown).
The demultiplexer 310 demultiplexes input streams. For example, if MPEG-2 TS is input, the demultiplexer 310 demultiplexes the MPEG-2 TS and splits the demultiplexed MPEG-2 TS into a video signal, an audio signal and a data signal. In this case, the stream signal input to the demultiplexer 310 may be the stream signal output from the tuner 110, the demodulation module 120, or the external device interface module 135.
The video processor 320 can process the demultiplexed video signal. To this end, the video processor 320 includes a video decoder 325 and a scaler 335.
The video decoder 325 decodes the demultiplexed video signal, the scaler 335 performs scaling to output resolution of the decoded video signal through the display module 180.
Also, the video decoder 325 may include decoders having various specifications. For example, if the demultiplexed video signal is an encoded video signal of the MPEG-2 specification, it may be decoded by an MPEG-2 decoder.
Also, for example, if the demultiplexed video signal is an encoded video signal of the H.264 specification based on a Digital Multimedia Broadcasting (DMB) mode or DVB-H mode, it may be decoded by an H.264 decoder.
The video signal decoded by the video processor 320 is input to the mixer 350.
The OSD generator 340 generates an OSD signal in accordance with input of the user or by itself. For example, the OSD generator 340 may generate a signal for displaying various kinds of information on the screen of the display module 180 in the form of graphic or text based on the control signal from the user input interface module 150. The generated OSD signal may include various data such as a user interface screen of the display device 100, a screen of various menus, widget, and icon.
For example, the OSD generator 340 may generate a signal for displaying broadcast information based on EPG or caption of broadcast video.
The mixer 350 mixes the OSD signal generated by the OSD generator 340 with the decoded video signal processed by the video processor 220. The mixed signal is provided to the formatter 360. As the decoded broadcast video signal or the external input signal is mixed with the OSD signal, the OSD may be overlaid on the broadcast video or the external input video.
The frame rate converter (FRC) 355 converts a frame rate of the input video. For example, the frame rate converter 355 converts a frame rate of 60 Hz to a frame rate of 120 Hz or 240 Hz. If the frame rate converter 355 converts the frame rate of 60 Hz to the frame rate of 120 Hz, a first frame may be inserted between another first frame and the second frame, or a third frame predicted from the first frame and the second frame may be inserted between the first frame and the second frame.
If the frame rate converter 355 converts the frame rate of 60 Hz to the frame rate of 240 Hz, three same frames may be inserted between another first frame and the second frame, or the third frame predicted from the first frame and the second frame may be inserted between the first frame and the second frame. The input frame rate may be maintained without separate conversion.
The formatter 360 receives an output signal of the frame rate converter 355, changes a format of the signal to conform to the display module 180, and then outputs the changed format. For example, the formatter 360 may output R, G, B data signals. The R, G, B data signals may be output by low voltage differential signaling (LVDS) or mini-LVDS.
The audio processor (not shown) in the control module 170 may perform audio processing of the demultiplexed audio signal. To this end, the audio processor may include various decoders.
If the demultiplexed audio signal is an encoded audio signal, the audio processor in the control module 170 may decode the encoded audio signal. For example, the demultiplexed audio signal may be decoded by an MPEG-2 decoder, MPEG-4 decoder, AAC decoder, or AC-3 decoder. Also, the audio processor in the control module 170 can process base, treble and sound volume control.
The data processor (not shown) in the control module 170 can perform data processing of the demultiplexed data signal. If the demultiplexed data signal is an encoded data signal, the data processor in the control module 170 may decode the encoded data signal. The encoded data signal may be electronic program guide (EPG) information that includes broadcast information such as start time and end time of a broadcast program broadcasted from each channel. For example, the EPG information may be ATSC-Program and System information protocol (ATSC-PSIP) information in case of the ATSC mode, and may include DVB-Service Information (DVB-SI) in case of the DVB mode.
The ATSC-PSIP information or the DVB-SI information may be information included in the aforementioned stream, i.e., a header (4 byte) of the MPEG-2 TS.
