The decoder 103 decodes the video signal among the decomposed signals and sends the audio signal to the audio processor 104. At this time, the data accompanying the audio signal is sent to the CPU 109 and processed there.

  The audio processor 104 decodes the audio signal received from the decoder 103. Since audio signals have many formats, the audio processor 104 normally performs audio signal decoding processing. However, the present invention is not limited to this, and the audio signal may be decoded by the decoder 103 or the CPU 109. The processed audio signal is sent to the speaker 105.

  The speaker 105 outputs the audio signal decoded by the audio processor 104. In addition, although this embodiment shows the form of a television provided with the display part 112 and the speaker 105, it is not limited to this, For example, BD (Blu-Ray) recorder or STB (Set Top Box) etc. In this case, an audio signal may be output to an external device instead of the speaker 105.

  Remote control communication unit 106 receives a control signal from a remote control (not shown). Examples of the remote controller that transmits a control signal include an infrared remote controller that transmits a signal in one direction or a wireless remote controller that transmits a signal in both directions. The control signal received by the remote control communication unit 106 is sent to the CPU 109.

  The external input unit 107 receives a signal output from the video output unit 208 of the PC unit 20. Examples of the external input unit 107 include an HDMI interface or a DVI-D terminal. The signal received by the external input unit 107 includes decoded data or data in a compressed format (for example, data in MPEG2 or MPEG4 format).

  The audio signal received by the external input unit 107 is output to the audio processor 104. On the other hand, the video signal received by the external input unit 107 is output to the graphic memory 110 and developed. For example, when the video signal received by the external input unit 107 is a compressed image, the received video signal is sent to the graphic memory 110 once via the decoder 103. Note that there is no substantial difference in the video signal output to the graphic memory 110 depending on whether or not the signal passes through the decoder 103.

  The memory 108 is a memory that stores a program or data.

  The CPU 109 is a CPU that controls the entire TV unit 10.

  The graphic memory 110 holds two or more videos and display data. Examples of display data include data such as data broadcasting, OSD (on-screen display) data, and setting menus. The graphic memory 110 is composed of a plurality of planes, and each plane can be superimposed or alpha blended.

  The graphic controller 111 combines video and display data held in the graphic memory 110 to create one screen. That is, the graphic controller 111 performs, for example, enlargement / reduction or position setting of a plurality of planes according to the control from the CPU 109, and creates a final screen by combining them. This final screen is sent to the display unit 112. The graphic memory 110 and the graphic controller 111 correspond to the content composition unit 14 shown in FIG.

  The display unit 112 displays the video received from the graphic controller 111. For example, video may be displayed on a display device such as a liquid crystal panel, or video data may be output to an external device.

  A LAN (Local Area Network) controller 113 is connected to an external device through a network. The LAN controller 113 may be connected to another device according to a home network standard such as DLNA (Digital Living Network Alliance) or may be connected to a video service through the Internet. The connection with the external device may be either wired or wireless. The video signal acquired from the LAN controller 113 is not particularly limited, but is preferably handled in the same manner as the video signal acquired through the RF receiving unit 101.

  The I / F unit 114 is an interface unit that controls LAN, USB, serial, or the like. The I / F unit 114 exchanges control information including a still image with the PC unit 20. Note that the transmission / reception method of control information in the I / F unit 114 is not particularly limited.

  The power supply unit 115 is a power supply circuit in the TV unit 10. The power supply unit 204 is a power supply circuit in the PC unit 20. These power supply units 115 and 204 are supplied with power from a common power supply 150. At this time, it is desirable to receive power from one AC plug.

  The input unit 201 receives input from the outside. Thus, the PC unit 20 may have its own input unit. As the input unit 201, for example, it is preferable that a Bluetooth wireless keyboard or a wireless mouse can be used.

  The IO processor 202 controls various external interfaces.

  The LAN controller 203 is connected to the IP network. Note that the LAN controller 113 and the LAN controller 203 preferably share one IP address with each other. Further, when the TV unit 10 and the PC unit 20 are provided with individual LAN controllers 113 and 203, respectively, it is preferable to have a bridge function inside the television 1 with a built-in PC. Thereby, for example, when connecting a wired LAN, the TV unit 10 and the PC unit 20 can be simultaneously connected to the network by simply inserting one LAN cable.

  A memory 205 is a memory of the CPU 206 that performs various controls.

  The CPU 206 comprehensively controls each block included in the PC unit 20. For example, the compressed PC content is decoded by software and converted to the original PC content. In the present embodiment, the PC unit 20 does not include hardware such as the decoder 103 in the TV unit 10. However, the present invention is not limited to this. For example, the PC unit 20 may include hardware such as the decoder 103.

  The graphic controller 207 speeds up graphic processing during video rendering.

  The video output unit 208 outputs the video signal processed by the graphic controller 207. Examples of the format of the output video signal include a format that can be output via an interface of the HDMI standard. The audio signal is also output to the TV unit 10 in the same manner as the video signal.

  The storage unit 209 permanently stores PC content acquired through the Internet 8 or the recording disk 7. Examples of the storage unit 209 include a hard disk, a BD (Blu-ray Disc), a DVD (Digital Video Disc), or a USB (Universal Serial Bus) memory. The CPU 206 reproduces the video acquired via the network or the video stored in the storage unit 209 and transmits it to the TV unit 10.

  Here, the image is not limited to a moving image, and includes a screen created by an application such as music, a book (text), a photo (still image), a slide show, a word processing document, or a game.

(Details of composite video generation)
Next, details of processing for generating a display video (composite video) including a TV video and a PC video in the PC built-in television 1 according to this embodiment will be described below.

  First, when the user presses a predetermined button provided on the remote controller 9 or the PC built-in television 1, the PC built-in television 1 displays the TV image whose display mode is processed in the TV unit 10 and the PC processed in the PC unit 20. The mode is changed to a mode for simultaneously displaying video on the display 2 (referred to as a simultaneous display mode).

  When the display mode in the PC built-in television 1 is changed to the simultaneous display mode, the control unit 19 in the PC unit 10 sends the PC video processed in the PC unit 20 to the control information communication unit 18 and the PC video. And instructs the PC unit 20 to output a display related information acquisition request including size designation information for designating the display size of the TV video. Upon receiving the instruction, the control information communication unit 18 outputs a PC video and display related information acquisition request to the PC unit 20.

  When the control information communication unit 25 of the PC unit 20 receives the acquisition request output from the TV unit 10, the control unit 27 sends the PC video processed in the content processing unit 21 to the TV unit 10 to the content transmission unit 23. Instruct to output. Upon receiving the instruction, the content transmission unit 23 outputs the PC video to the TV unit 10.

  At the same time, the control unit 27 instructs the control information communication unit 25 to output size designation information for designating the display size of the PC video and TV video to the TV unit 10. Upon receiving the instruction, the control information communication unit 25 outputs size designation information to the TV unit 10.

  When the content receiving unit 16 of the TV unit 10 acquires the PC video and the control information communication unit 18 receives the size designation information, the control unit 19 sizes the acquired PC video and the TV video processed by the content acquiring unit 15. The content composition unit 14 is instructed to generate a display video by scaling and compositing based on the designation information. Upon receiving the instruction, the content composition unit 14 generates a composite video obtained by reducing the display size of the acquired PC video and TV video based on the size designation information, and combines the generated composite video with the TV video. As a result, a display video to be displayed on the display 2 is generated in the content composition unit 14.

  At this time, the display positions of the TV video and the PC video in the display video may be set in advance in the TV unit 10. For example, the position coordinates on the display where an arbitrary vertex (for example, the upper left vertex in the case of a rectangle) of the generated composition video may be set. Of course, the position designation information for designating the display position of the TV video and the PC video on the display 2 may be output to the TV unit 10 together with the size designation information.

  The generation of the display video in the content composition unit 14 will be described more specifically. The graphic controller 111 uses the graphic memory 110 to write the data representing the TV video and the data representing the PC video. A display video is generated by combining the written second plane. At this time, the data representing the TV video is written to the first plane so as to have a display size designated by the size designation information, and the data representing the PC video has a display size designated by the size designation information. Are written in the second plane.

  Finally, the display video generated by the content composition unit 14 is output to the display 2 via the video output unit 11. As a result, a two-screen image of a TV image and a PC image is displayed on the display 2.

  Here, the display size of the TV image and the PC image specified in the size specifying information may be a predetermined size, or the mouse 5 or the like (that is, connected to or provided in the PC built-in television 1). The size may be set by the user via the operation device).

  In this way, the TV 1 with a built-in PC enhances the affinity between two different units, operates the TV unit 10 to operate both in cooperation, and simultaneously generates images generated in both units on the display 2. Can be displayed.

(Change of layout of TV video and PC video in display video)
The display position and display size of the TV image and the PC image displayed on the display 2 can be changed as appropriate according to user settings via the operation device (for example, the mouse 5) provided in the PC unit 20. FIG. 4 is a diagram illustrating a signal transmission flow when the display layout is changed using an operation device (such as the mouse 5).

  When the display position and the display size of the TV image and the PC image are changed using the mouse 5, a signal (operation signal) transmitted from the mouse 5 in response to a user input is transmitted via the user input unit 26 to the control unit 27. (Step S1). The control unit 27 analyzes the operation signal to determine whether the signal is for operating the PC unit 20 or a signal for changing the display layout in the display video. If it is determined to be the former, each block in the PC unit 20 is controlled according to the contents of the operation signal. As a result of these processes, the user can operate the PC unit 20 using the mouse 5 or the like.

  On the other hand, when determining that the operation signal is a signal for changing the display layout in the display video, the control unit 27 converts (generates) the layout information into layout information according to the content of the operation signal (step S2). It transmits to the TV unit 10 through the control information communication part 25 (step S3). The layout information is input to the control unit 19 of the TV unit 10 via the control information communication unit 18. Based on the input layout information, the control unit 19 controls the content synthesis unit 14 to synthesize the display video with the changed layout (step S4). The video output unit 11 displays the display video synthesized by the content synthesis unit 14 on the display 2 (step S5). As a result, the TV video and the PC video are displayed in the designated display size at the display position designated by the layout information in the display video.

  That is, every time the display position or display size of the TV video and PC video is changed by an operation input from the PC unit 20, the content composition unit 14 generates a new display video. Accordingly, the display position and display size of the TV video and the PC video can be changed as appropriate in accordance with an operation input from the PC unit 20 side.

  For example, as shown in FIG. 5A, when the TV image 40 and the PC image 41 are simultaneously displayed on the display 2, first, the mouse 5 is operated to move the mouse point (object) 42 to the PC image 41. And the mouse point 42 is moved in the left direction by dragging the mouse 5 ((b) and (c) in FIG. 5). FIG. 5 is a diagram showing an example of changing the display size of both videos when the TV video 40 and the PC video 41 are displayed so as not to overlap each other on the PC built-in television 1 according to the embodiment of the present invention. is there. As a result, the display size of the PC video 42 can be enlarged and the display size of the TV video 41 can be reduced ((d) in FIG. 5).

  As described above, the display 2 changes the display size of the PC video 41 by moving the position of the mouse point 42 that designates the PC video 41 with the mouse 5, and adjusts the TV size according to the display size of the PC video 41. The video 40 can be displayed so as not to overlap. That is, the user can change the display position and display size of the TV video 40 and the PC video 41 in the display video by operating from the PC unit 20 side using the mouse 5. This is because the content composition unit 14 generates a display video until the PC video 41 reaches the position of the mouse point 42 after the movement after moving the predetermined pixel from the position of the mouse point 42 before the movement starts. What should I do?

  The layout information preferably includes size specifying information for specifying a display size, but may include information for specifying a display position.

  Further, the TV unit 10 may continuously output the position information to the PC unit 20, but when receiving a signal indicating that the position is specified by the user on the operation device, the TV unit 10 receives the position information from the PC unit 20. It is preferable to transmit information. That is, the PC unit 20 may continuously output display-related information including layout information to the TV unit 10, but when receiving a signal indicating a change in position by the user via the operation device, the layout information Is preferably output. Thereby, for example, when the application of the PC unit 20 is executed using the mouse 5, it is possible to prevent the layout from being changed by mistake.

  Note that the timing for transmitting the position information is not limited to this. In addition, the TV unit 10 is configured such that the mouse point (object) 42 is positioned at an arbitrary position on the PC video 41 for a certain period of time. Alternatively, the position information may be transmitted.

  As described above, in the television 1 with a built-in PC according to the present embodiment, the user can change the display layout in the display video using the operation device in which information is input to the PC unit 20. In other words, the fact that the layout of the display video output from the TV unit 10 can be changed by the pointing device with high operability such as the mouse 5 instead of the remote control 9 has a great merit for the user. This is because the pointing device such as the mouse 5 can freely specify an arbitrary point on the display 2 and can be visually recognized as compared with the operation of the remote controller 9. Therefore, the user who uses the television 1 with a built-in PC according to the present embodiment can easily change the display layout of the TV video and the PC video simultaneously displayed on the display 2.

(Other examples of layout changes)
In the above-described layout change in the display video, the case where the TV video 40 is reduced and the PC video 41 is enlarged is described as an example, whereas the TV video 41 is enlarged and the PC video 41 is reduced. You may let them.

  For example, as shown in FIG. 6A, when the TV image 40 and the PC image 41 are simultaneously displayed on the display 2, the right end of the PC image 41 is designated by operating the mouse 5 and the mouse point 42. . FIG. 6 shows another example of changing the display size of both videos when the TV video 40 and the PC video 41 are displayed so as not to overlap each other on the PC built-in television 1 according to the embodiment of the present invention. FIG. From this state, the mouse 5 is dragged rightward to move the mouse point 42 (FIGS. 6B and 6C). As a result, as shown in FIG. 6D, the display size of the PC video 42 can be reduced and the display size of the TV video 41 can be increased.

  In the above-described layout change example, the size of the TV video and the PC video is simply changed. However, the present invention is not limited to this. For example, the TV video and the PC video are not arranged in the display video. When there is an area, the display position can be changed without changing the display size of the PC video. In this case, it may be set in advance whether or not the display size or the display position is changed when the position on the PC video is specified by the object, or may be set via the operation device each time. Also good.

(Window display of PC video 41)
In the PC built-in television 1, as shown in FIG. 7, a window 43 displayed as a part of the TV video 40 can be generated as a display video, and the PC video 41 can be arranged in the window 43. FIG. 7 shows an example of changing the display size of the window 43 when the PC video 41 is arranged in the window 43 displayed as a part of the TV video in the PC built-in television according to the embodiment of the present invention. FIG.

  When a display image including a window 43 shown in a partial area on the TV image 40 is generated, the display position and the display size of the window 43 are included in the display related information output from the PC unit 20 to the TV unit 10. Contains specified window layout information.

  The content composition unit 14 of the TV unit 10 arranges the window 43 in a partial area on the TV video 40 specified by the window arrangement information received from the PC unit 20. Then, a display video in which the PC video 41 is applied to the arranged window 43 is generated. By outputting the generated display image to the display 2, an image as shown in FIG. 7A is displayed on the display 2.

  In addition, in the display video in which the window 43 is arranged in a partial area on the TV video 40, the display position or display size of the window 43 can be changed. That is, the display position or display size of the window 43 can be changed by operating an operation device such as the mouse 5 in the same manner as the layout change of the TV video 40 and the PC video 41 in the display video described above.

  For example, as shown in FIG. 7A, when a window 43 in which a PC video 41 is inserted is displayed in a partial area on the TV video 40, the upper left corner of the window 43 is designated by the mouse point 42. Then, the mouse 5 is dragged so that the mouse point 42 moves to the upper left. As a result, the display size of the window 43 is enlarged as shown in FIG. On the other hand, when reducing the display size of the window 43, for example, as shown in FIG. 8A, the lower right corner of the window 43 is designated by the mouse point 42, and the mouse point 42 moves to the lower right. The mouse 5 is dragged as shown in FIG. 8 (b). As a result, the display size of the window 43 is reduced as shown in FIG.

  Further, when changing the display position of the window 43 on the TV video 40, for example, as shown in FIG. 9A, the upper end of the window 43 arranged on the TV video 40 is designated by the mouse point 42. By dragging the mouse 5 so that the mouse point 42 moves upward, the window 43 moves upward (FIG. 9B), and the lower end of the window 43 is moved to the mouse as shown in FIG. 9C. By designating with the point 42 and dragging the mouse 5 so that the mouse point 42 moves downward ((d) in FIG. 9), the window 43 moves downward ((e) in FIG. 9).

  On the other hand, as shown in FIG. 10, when the TV image 40 and the window 43 are displayed on the display 2 so as not to overlap with each other, the display sizes of both can be changed. FIG. 10 shows how the display size of the window 43 of the PC video 41 is changed when the TV video 40 is displayed so as not to overlap the window 43 of the PC video 41 in the television with built-in PC 1 according to an embodiment of the present invention. It is a figure which shows the example of a case.
