  FIG. 2 is a diagram illustrating a system configuration of the image display apparatus 1.

  As shown in FIG. 2, the image display device 1 is roughly composed of three components: a television SoC (system on a chip) 11, a mobile SoC 12, and an HDMI (high-definition multimedia interface) conversion circuit 13.

  The television SoC 11 is a system in which various modules necessary for operating the image display device 1 as a television receiver are integrated on one chip. An interface standard capable of transferring both a digital video signal and an audio signal through a connector 21 for inputting a television broadcast signal received by a television antenna or the like to the casing peripheral wall of the image display apparatus 1 and a single cable. The connector 22 for connecting the HDMI-compliant HDMI cable, the light receiving unit 23 for receiving, for example, an operation signal transmitted from the remote controller 1A using infrared rays as a carrier wave, and the remote controller 1A. 1 is provided with an operation unit 24 for receiving an operation instruction for 1, an LCD (liquid crystal display) panel 25 for image output, a speaker 26 for sound output, and the like. A DAC (digital / analog converter) 27 for converting a digital signal into an analog signal is provided between the speaker 26 and the television SoC 11.

  A television broadcast signal input via the connector 21 is supplied to the television SoC 11. Further, an operation signal received by the light receiving unit 23 from the remote controller 1A is also supplied to the television SoC 11. The television Soc 11 selects a television broadcast signal of a target channel from television broadcast signals input via the connector 21 based on an operation signal from the light receiving unit 23 or an operation signal from the operation unit 24.

  As shown in FIG. 2, the television SoC 11 includes a graphics processing unit 111, a video decoder 112, an audio decoder 113, an HDMI separation unit 114, scaling units 115 and 116, an overlay unit 117, a blending unit 118, an image processing unit 119, a mixing unit. Part 120 and the like. The television SoC 11 sends graphics data, video data, and audio data included in broadcast program data carried by the television broadcast signal of the selected channel to the graphics processing unit 111, the video decoder 112, and the audio decoder 113, respectively. Distribute. Each of the graphics processing unit 111, the video decoder 112, and the audio decoder 113 performs predetermined processing such as decoding on each supplied data. Here, each data before decoding input to the video decoder 112 and the audio decoder 113 is referred to as video data and audio data, and each data after decoding output from the video decoder 112 and the audio decoder 113 is a video signal, This is called an audio signal. The graphics data is data for drawing, for example, an operation guide object such as a menu displayed on the video.

  A signal input via the connector 22 is also supplied to the television SoC 11 and separated into a video signal and an audio signal by the HDMI separation unit 114. The video signal output from the video decoder 112 is supplied to the overlay unit 117 via the scaling unit 115, while the video signal output from the HDMI separation unit 114 is supplied to the overlay unit 117 via the scaling unit 116. The scaling units 115 and 116 are processing units for enlarging / reducing the resolution of the video signal, that is, the image size, and the overlay unit 117 includes each video of the two video signals supplied from the scaling units 115 and 116, respectively. It is a processing part which produces | generates the video signal of one video which becomes. By the scaling units 115 and 116 and the overlay unit 117, the image display apparatus 1 creates, for example, a video (picture-in-picture) in which a reduced video of the other video signal is inserted into a video of one video signal. It is possible.

  For example, the television broadcast program data (first video) recorded by a user with a DVD (digital versatile disc) recorder with a built-in hard disk is viewed on the image display device 1 while the user is viewing the currently broadcast television broadcast program data ( Assume that the user wants to confirm (second video). In the present image display device 1 equipped with the television SoC 11 having the scaling units 115 and 116 and the overlay unit 117, for example, the second image reduced to the first video (displayed in full screen) in response to the operation of the remote controller 1A. It is possible to simultaneously present the first and second images to the user by inserting the images. Of course, on the contrary, the reduced first video can be inserted into the second video. Further, in accordance with the operation of the remote controller 1A, the video to be displayed on the full screen and the image to be reduced and fitted can be interchanged.

  The blending unit 118 is a processing unit that generates a video signal of a video in which the object drawn by the graphics processing unit 111 is superimposed on the video of the video signal output from the overlay unit 117. The image processing unit 119 controls display of the video signal output from the blend unit 118 on the LCD panel 25. At this time, the image processing unit 119 also performs, for example, super-resolution processing for improving the image quality on the video signal.

  Also, the audio signal output from the audio decoder 113 and the audio signal output from the HDMI separation unit 114 are each output from the television SoC 11 via the mixing unit 120, subjected to analog conversion by the DAC 27, and output from the speaker 26. The

  On the other hand, the mobile SoC 12 is a system in which various modules necessary for operating the image display apparatus 1 as a mobile phone are integrated on one chip. An antenna 28 for transmitting / receiving data to / from the base station 3 shown in FIG. 1 is further provided on the peripheral wall of the housing of the image display apparatus. The mobile SoC 12 performs communication with the content service provider 5 shown in FIG.

  Of the data from the content service provider 5 input via the antenna 28, graphics data is supplied to the graphics processing unit 121. Video data and audio data are supplied to a video decoder 122 and an audio decoder 123, respectively. Each of the graphics processing unit 121, the video decoder 122, and the audio decoder 123 performs predetermined processing such as decoding on each supplied data. Then, the mobile SoC 12 outputs a video signal and an audio signal as a result of these processes. The graphics processing unit 121 also executes processing for creating various operation screens including an initial screen called a standby screen, for example.

  In other words, the mobile SoC 12 is a port of the SoC installed in a general mobile phone as it is. The video signal output from the mobile SoC 12, which is an SoC mounted on this general mobile phone, has an RGB parallel video signal format and a resolution of 320 × 200 pixels or 640 × 480 pixels. On the other hand, at present, the video signal that can be input from the external device to the television SoC 11 is the HDMI format (1920 × 1080 pixels). Therefore, in order to input the video signal output from the mobile SoC 12 to the television SoC 11 and control the display of the video signal on the television SoC 11 side, it is necessary to change the specifications of one SoC at high cost.

  Therefore, when the image display device 1 of the present embodiment has a completely new idea of adding the mobile SoC 12 to the image display device 1 that is a television receiver, first, the mobile SoC 12 and the television SoC 11 are connected. By providing the HDMI conversion circuit 13 between them, video signals can be transmitted and received between the mobile SoC 12 and the television SoC 11 without requiring any changes in specifications for either the mobile SoC 12 or the television SoC 11. . Second, a control signal line 14 for inter-CPU communication is laid between the mobile SoC 12 and the television SoC 11, and a user interface (UI) command issued when a general mobile phone is operated with an operation button, etc. Is supplied from the television SoC 11 to the mobile SoC 12, so that the mobile SoC 12, which is an SoC installed in a general mobile phone, is used as it is, and the user uses the remote controller 1A for viewing the television broadcast program data. Various services provided by the content service provider 5 for mobile phones can be used.

  When the television SoC 11 receives an operation signal instructing to turn on the power from the light receiving unit 23 or the operation unit 24, the television SoC 11 transmits the initial screen to be displayed on the LCD panel 25 to the mobile SoC 12 via the control signal line 14. The layout information indicating the layout configuration of the display area is transmitted. For example, when the initial screen is configured as shown in FIG. 3, the television SoC 11 transmits layout information corresponding to an area (application data area) indicated by “a2” in FIG. 3 to the mobile SoC 12. Recent mobile phones with multiple functions create and display an initial screen (standby screen) on which icons for each function are arranged. The SoC mounted on this type of mobile phone has a function of creating a screen based on given layout information, for example, for creating a screen according to the orientation of the display panel. Therefore, the mobile SoC 12 that has received the layout information creates an initial screen in which icons are arranged on the application data area a2 shown in FIG. 3 based on the layout information, and outputs a video signal of the created initial screen.

  The video signal output from the mobile SoC 12 is supplied to an HDMI conversion circuit 13 provided between the mobile SoC 12 and the television SoC 11. The HDMI conversion circuit 13 converts the format of this video signal into a format that the television SoC 11 can input from an external device, that is, a format compliant with the HDMI standard, and supplies the converted format to the television SoC 11.

  The television SoC 11 reduces the image of the image signal output from the video decoder 112 to a size that can be arranged in the area (TV data area) indicated by “a1” in FIG. The video signal received from the mobile SoC 12 via the HDMI conversion circuit 13 (output from the HDMI separation unit 114) is combined by the overlay unit 117, and the video signal created and output by the overlay unit 117 is combined. Display control is performed on the LCD panel 25.

  FIG. 4 is a diagram illustrating an example of an initial screen displayed on the LCD panel 25 of the image display device 1 through the above-described procedure when the power is turned on.

  The video indicated by “b1” in FIG. 4 is a video of the currently broadcast television broadcast program data input from the connector 21, and the video b1 displayed on the initial screen is an icon for the TV function. It is what is displayed. Here, an example is shown in which the video itself of the currently broadcast television broadcast program data is displayed as an icon for the TV function, but instead of this, an object (graphics) designed for the TV function is displayed. You may make it do. Also, the icon group indicated by “b2” in FIG. 4 is an icon group arranged on the initial screen created by the mobile SoC 12 (based on the layout information received from the television SoC 11).

  For example, if the image display apparatus 1 is powered on using the remote controller 1A and the user who is presented with the initial screen wants to watch the television broadcast program data broadcast by the TV broadcast station 2, the icon b1 is remoted. On the other hand, if the user wants to use various services provided by the content service provider 5 for the mobile phone, the icon corresponding to the service to be used is selected from the icon group b2 by the remote controller 1A. .

  When the operation signal indicating that the icon b1 is selected is received from the light receiving unit 23, the television SoC 11 displays the image of the currently broadcast television broadcast program data on the LCD panel 25 as shown in FIG. Thus, the scaling units 115 and 116 and the overlay unit 117 are operated. At this time, the television SoC 11 preferably transmits a command to stop the operation to the mobile SoC 12 via the control signal line 14 (from the viewpoint of power saving).

  Further, for example, it is assumed that the user wants to use the internet shopping service provided by the content service provider 5 and selects the icon b21 for the internet shopping service from the icon group b2. When the television SoC 11 receives an operation signal indicating that one of the icons in the icon group b2 (in this case, the icon b21) is selected from the light receiving unit 23, the icon is selected via the control signal line 14. A user interface (UI) command indicating that it has been sent is transmitted to the mobile SoC 12. At this time, the television SoC 11 reconfigures the screen so that the application data area a2 shown in FIG. 3 is changed as shown in FIG. 6, and the layout information corresponding to the entire display area of the LCD panel 25 is transferred to the mobile SoC 12 Resend to.

  The UI command that the television SoC 11 outputs to the control signal line 14 toward the mobile SoC 12 is the same as the command that is issued when a general cellular phone is operated with an operation button. Accordingly, the mobile SoC 12 having input this UI command starts an application program for executing access to the content service provider 5 that provides the online shopping service, and (a layout corresponding to the entire display area of the LCD panel 25) Since the information is received again), a display screen in which the image output by the application program is arranged in the entire display area of the LCD panel 25 is created, and a video signal of the created display screen is output.

  As described above, the video signal output from the mobile SoC 12 is supplied to the television SoC 11 via the HDMI conversion circuit 13. Here, as shown in FIG. 7, the television SoC 11 has the scaling units 115 and 116 so that the video of the video signal supplied from the mobile SoC 12 (via the HDMI conversion circuit 13) is displayed on the LCD panel 25 on the full screen. Then, the overlay unit 117 is operated. When the user further performs an operation with the remote controller 1A while viewing the screen shown in FIG. 7, the television SoC 11 transmits a UI command corresponding to the operation to the mobile SoC 12 via the control signal line 14. Thereby, the act of operating the operation buttons of the mobile phone while looking at the display panel of the mobile phone, more specifically, various types provided for the mobile phone by the content service provider 5 The act of using the service can also be performed by operating the remote controller 1A while looking at the LCD panel 25 of the image display apparatus 1.

  That is, in the present image display device 1 having a completely new configuration of adding the mobile SoC 12 (in addition to the television SoC 11), the user simply enters a contract with the mobile phone operator, and the image display device 1 In addition to viewing the television broadcast program data broadcasted by the TV broadcast station 2 after purchasing, various services provided by the content service provider 5 for mobile phones can be used immediately.

  Further, the image display apparatus 1 pays attention to the fact that the television SoC 11 has a mechanism for inputting a signal in the HDMI format, and is provided by interposing the HDMI conversion circuit 13 between the mobile SoC 12 and the television SoC 11. The video signal can be supplied from the mobile SoC 12 to the television SoC 11 without any specification change to either the mobile SoC 12 or the television SoC 11, and the control signal line 14 is provided between the mobile SoC 12 and the television SoC 11. By laying down and supplying the same UI command to the mobile SoC 12 from the television SoC 11 as when operating the operation buttons on the mobile phone, the existing mobile SoC 12 can be used as it is. In other words, the image display apparatus 1 realizes the above-mentioned “use various services provided by the content service provider 5 for mobile phones” at a minimum cost.

  By the way, in the above description, when the icon b1 is selected on the initial screen shown in FIG. 4, the video of the currently broadcast television broadcast program data is displayed on the LCD panel 25 on the full screen as shown in FIG. When any icon in the icon group b2 is selected, as shown in FIG. 7, an example in which an image output by an application program operating on the mobile SoC 12 is displayed on the LCD panel 25 on the full screen is shown. Since the television SoC 11 of the image display device 1 includes the scaling units 115 and 116 and the overlay unit 117, the present invention is not limited to the example described above, and various modifications can be made.

  For example, as shown in FIG. 8, it is also possible to display the video of the currently broadcast television broadcast program data and the image output by the application program operating on the mobile SoC 12 side by side on the LCD panel 25. As shown in FIG. 9, it is also possible to display a reduced video image of the currently broadcasted television broadcast program data in an image output from an application program operating on the mobile SoC 12. As described above, the two video display modes can be applied in various ways.

  FIG. 10 is a timing chart showing the operation procedure of the image display apparatus 1.

  When receiving the power-on instruction, the television SoC 11 transmits layout information corresponding to the application data area a2 for the initial screen to the mobile SoC 12 ((1) in FIG. 10). Based on the layout information, the mobile SoC 12 creates an initial screen in which the icon group b2 is arranged in the application data area a2 ((2) in FIG. 10), and transmits a video signal of the created initial screen to the television SoC 11 (see FIG. 10 (3)). Although not shown here, as described above, transmission of the video signal from the mobile SoC 12 to the television SoC 11 is performed via the HDMI conversion circuit 13. Then, the television SoC 11 receiving the video signal of the initial screen from the mobile SoC 12 creates an initial screen incorporating the TV function icon b1 and displays it on the LCD panel 25 ((4) in FIG. 10).

  If the icon b1 is selected after the initial screen is displayed ("A" in FIG. 10), the television SoC 11 displays the image of the currently broadcast television broadcast program data on the LCD panel 25 in full screen (FIG. 10). 10 (5)). At this time, the television SoC 11 transmits a command to stop the operation to the mobile SoC 12 ((6) in FIG. 10).
