The video decoder 272a decodes the demultiplexed video signal and the scaler 272b performs a scaling to enable resolution of the decoded video signal to be outputtable from the display unit 280. And, the video signal decoded by the video processor 272 is inputted to the mixer 274.
The OSD generator 273 generates an OSD signal in response to a user input or by itself. For instance, the OSD generator 273 can generate a signal for displaying various information as a graphic or text on a screen of the display unit 280 based on a control signal from the user interface unit 250.
The mixer 274 mixes the OSD signal generated from the OSD generator 273 and the decoded video signal video-processed by the video processor 272 with each other. The mixed signal is provided to the formatter 276. Since a decoded broadcast video signal or an external input signal and an OSD signal are mixed together, an OSD may be displayed in a manner of overlaying a broadcast video or an external input video.
The frame rate converter (FRC) 275 can convert a frame rate of an inputted video. For instance, the frame rate converter 275 converts a frame rate to 120 or 240 Hz from 60 Hz. In case that the frame rate of 60 Hz is converted to 120 Hz, it is possible to insert a first frame between the first frame and a second frame or insert a third frame, which is predicted from the first frame and the second frame, between the first frame and the second frame. In case of converting a frame rate of 60 Hz to 240 Hz, it is possible to insert 3 frames of the same or 3 predicted frames. Meanwhile, it is possible to maintain an inputted frame rate without separate conversion.
The formatter 276 receives an input of an output signal of the frame rate converter 275 and then outputs the signal by changing a format of the signal to fit the display unit 280. For instance, the formatter 276 can output R/G/B data signal. In this case, the R/G/B data signal may be outputted as low voltage differential signaling (LVDS) or mini-LVDS.
Particularly, a multimedia device including a flexible display according to one embodiment of the present invention is described as follows.
First of all, the display unit 280 includes a flexible display and can be rolled up on an outer circumference of a guide bar (not shown in the drawing). In the display unit 280, a part rolled up on the outer circumference of the guide bar shall be named a first region and a part failing to be rolled up on the outer circumference of the guide bar shall be named a second region. Since the display unit 280 can be rolled up on the outer circumference of the guide bar, a size of each of the first and second regions may vary depending on an extent of the display unit 280 rolled up on the guide bar. In this case, a screen is situated within the second region failing to be rolled up on the outer circumference of the guide bar.
The receiving unit 205 receives a content and metadata corresponding to the content from a source device. In this case, the source device may include one of a broadcasting station, a contents provided, a service provider and the like. In this case, the contents may conceptionally include all contents, which include a broadcast signal, a VOD (video on demand), an application and the like, receivable from the source device. And, the metadata may include such information as a content name, a running time, an optimized resolution, an aspect ratio and the like.
The control unit 270 extracts an aspect ratio information of the content from the received metadata. In this case, the aspect ratio means a width to length ratio of a screen. Using the aspect ratio information, the control unit 270 can obtain a screen aspect ratio optimized for the received content.
In accordance with the extract aspect ratio information, the control unit 270 adjusts a vertical width of the second region of the flexible display. In particular, the control unit 270 adjusts the vertical width of the second region of the flexible display to fit the extracted aspect ratio, thereby enabling a user to watch the content on a full screen without a margin or blank. This shall be described in detail with reference to
The adjustment of the vertical width of the second region of the flexible display is performed in a manner of adjusting an extent of the flexible display rolled up on the outer circumference of the guide bar. If the extent of the flexible display rolled up on the outer circumference of the flexible display increases, a size of the screen decreases correspondingly. If the extent of the flexible display rolled up on the outer circumference of the flexible display decreases, a size of the screen increases correspondingly. Since a horizontal width of the flexible display is already determined depending on a product, it is able to adjust a size of the screen by adjusting the vertical width of the flexible display.
Meanwhile, since a hard type display is used according to the related, a blank is left on top, bottom, right and/or left side of a screen depending on an aspect ratio of a screen. Hence, it may cause a problem that user's immersion is disturbed. Yet, according to the present invention, a size of a screen is controlled in a manner that a vertical width of a second region of a flexible display is adjusted depending on an aspect ratio optimized for a content, whereby a user can watch the content on a full screen without blanks or margins.
Occasionally, a user may desire to watch a content at an aspect ratio of a screen preferred by the user instead of watching the content at an aspect ratio indicated by an information of a received metadata. In this case, the control unit 270 generates a GUI for receiving a command signal for selecting an aspect ratio of a screen and then controls the generated GUI to be displayed on the flexible display. In particular, the OSD generator 273 in the control unit 270 generates a GUI signal for aspect ratio selection and then delivers the GUI signal to the display unit 280. If so, the GUI is displayed on the display unit 280. The control unit 270 adjusts the vertical width of the second region of the flexible display in response to a screen aspect ratio inputted via the GUI. This shall be described in detail with reference to
The storage unit 240 may store a function or a lookup table for determining the vertical width of the second region in accordance with the screen aspect ratio in advance. In response to the screen aspect ratio, the control unit 270 detects the function by accessing the storage unit 240 and then determines the vertical width of the second region in accordance with the detected function. Alternatively, in response to the screen aspect ratio, the control unit 270 detects a value in the lookup table by accessing the storage unit 240 and then determines the vertical width of the second region in accordance with the detected value in the lookup table. The control unit 270 detects a width of the second region in a current state and is then able to determine whether to further roll up the flexible display on the outer circumference of the guide bar or release a rolled part of the flexible display from the outer circumference of the guide bar in accordance with the determined width of the second region.
The control unit 270 can determine whether caption data (subtitle image or text data), OSD data, widget application data or the like exists except video data included in the received content. For clarity, the caption data (subtitle image or text data), the OSD data, the widget application data or the like except video data shall be named subdata.
If a command signal for displaying the video data and the subdata separately is received through the received content itself or a user input, the control unit 270 partitions a screen within the flexible display and is then able to control the video data and the subdata to be displayed on a first partitioned region and a second partitioned region, respectively, in response to the received command signal. The OSD generator 273 in the control unit 270 converts the subdata to an OSD signal and is then able to deliver it to the second partitioned region. In this case, an aspect ratio of the screen may mean the aspect ratio of the first partitioned region for displaying the video data. Hence, the control unit 270 adjusts a vertical width of the second region of the flexible display to match a size of the first partitioned region to the aspect ratio. This shall be described in detail with reference to
In case that at least two contents are received by the receiving unit 205, the control unit 270 partitions a screen within the flexible display into a plurality of partitioned regions and then controls video data of different contents to be displayed on a plurality of the partitioned regions, respectively. According to an embodiment, the receiving unit 205 may include a plurality of tuners 210.
According to an embodiment, the video data in the content received by the receiving unit 205 may be displayed on the first partitioned region within the screen of the flexible display and a video data within a content included in a storage medium owned by a user may be displayed on the second partitioned region within the screen of the flexible display. In this case, the storage medium may include the storage unit 240 of the multimedia device 200 or an external storage medium (e.g., USB memory, etc.) connected to the multimedia device 200 via the external device interface unit 235. This shall be described in detail with reference to
While the multimedia device 200 is in the state of the standby mode, a light source of the display unit 280 is turned on in part to play a role as an illumination. If the multimedia device 200 is in the state of the standby mode, it may mean that a user does not use a unique function (e.g., a contents view, a search via internet, etc.) of the multimedia device 200. This shall be described in detail with reference to
In case that the multimedia device 200 is paired via network with such a device as a user's mobile phone, a home phone, an indoor thermometer and the like, the multimedia device 200 receives informations from the devices via the internal device interface (i.e., the network interface 230) or the external device interface unit 235 and then displays the received informations on the display unit 280, thereby play a role in guiding informations. This shall be described in detail with reference to
The sensor unit 260 can include at least one of an eye recognition sensor for recognizing a user's eye, a motion recognition sensor for recognizing a user's motion, a voice recognition sensor for recognizing a user's voice and the like.
In particular, the sensor unit 260 recognizes a user's eye using the eye recognition sensor and the control unit 270 is then able to adjust a height of the flexible display to enable a screen of the flexible display to fit a user's eye height. This shall be described in detail with reference to
The sensor unit 260 recognizes a user's motion using the motion recognition sensor and the control unit 270 is then able to adjust a height of the flexible display to enable a screen of the flexible display to be situated at a user-desired height. And, the storage unit 240 can store a control signal matching each user's motion. This shall be described in detail with reference to
The sensor unit 260 recognizes a user's voice using the voice recognition sensor and the control unit 270 is then able to adjust a height of the flexible display to enable a screen of the flexible display to be situated at a user-desired height. And, the storage unit 240 can store a control signal matching each user's voice.
Referring to
First of all, the network interface 401 receives packets from a network and transmits packets to the network. In particular, the network interface 401 receives a service, a content and the like from a service provider via the network. And, the network interface 401 corresponds to the receiving unit 205 shown in
The TCP/IP manager 402 manages a packet received by the multimedia device 400 and a packet transmitted by the IPTV 400. In particular, the TCP/IP manager 402 manages a packet delivery from a source to a destination. The TCP/IP manager 402 sorts the received packets to correspond to an appropriate protocol and then transmits the sorted packets to the service delivery manager 405, the service discovery manager 410, the service control manager 409 and the metadata manager 412.
The service delivery manager 403 is responsible for a control of the received service data. For instance, in case of controlling real-time streaming data, the service delivery manager 403 can use RTP/RTCP. In case of transmitting the real-time streaming data using RTP, the service delivery manager 403 parses the received data packet by the RTP and then transmits the parsed data packet to the demultiplexer 405 or saves the parsed data packet in the SI & Metadata DB 411. And, the service delivery manager 403 feeds back the network received data to a service side, which provides a service, using the RTCP.
The demultiplexer (Demux) 405 demultiplexes the received packets into audio data, video data, PSI (program specific information) data and the like and then transmits the demultiplexed data to the audio decoder 406, the video decoder 407 and the PSI (PSIP and/or SI) decoder 404, respectively.
The PSI & (PSIP and/or SI) decoder 404 decodes such service information as PSI (program specific information) and the like for example. In particular, the PSI & (PSIP and/or SI) decoder 404 receives a PSI section, a PSIP (program and service information protocol) section, an SI (service information) section and the like, which are demultiplexed by the demultiplexer 405, and then decodes the received sections.
Moreover, the PSI & (PSIP and/or SI) decoder 404 creates a database for the service information by decoding the received sections and then saves the database for the service information in the SI & Metadata DB 411. In this case, an aspect ratio information of a content may be included in the decoded service information.
The audio decoder 406 and the video decoder 407 decode the video data and the audio data, which are received from the demultiplexer 405, respectively. Subsequently, audio data decoded by the audio decoder 406 and video data decoded by the video decoder 407 are provided to a user through the display module (Display AN and OSD Module) 408.
The UI manager 414 and the service manager 413 manage overall states of the multimedia device 400, provide a user interface, and also manage other managers.
The UI manager 414 provides a GUI (graphic user interface) for a user using an OSD (on screen display) and the like. The UI manager 414 receives a key input from the user and then performs a receiver operation in response to the received input. For instance, if the UI manager 414 receives a key input for a channel selection from the user, the UI manager 414 transmits a corresponding key input signal to the service manager 413.
The service manager 413 controls such a manager associated with a service as the service delivery manager 403, the service discovery manager 410, the service control manager 409, the metadata manager 412 and the like.
The service manager 413 creates a channel map and then selects a channel in response to the key input received from the user interface manager 414 using the channel map. The service manager 413 receives a service information of a channel from the PSI & (PSIP and/or SI) decoder 404 and then configures an audio/video PID (packet identifier) of the selected channel in the demultiplexer 405.
