  An RF (Radio Frequency) receiving unit 101 receives a signal transmitted from the outside. That is, the RF receiving unit 101 is a video signal input unit that receives a digital broadcast signal such as a video signal transmitted wirelessly as terrestrial digital broadcast. Note that the signal received by the RF receiving unit 101 is not limited to a signal transmitted as terrestrial digital broadcast, and is transmitted as, for example, general analog broadcast, satellite broadcast, or cable television broadcast. It may be a signal.

  Examples of these signals include video signals digitized as a system such as MPG2 or MPEG4 in the case of digital broadcasting. The signal input to the RF receiving unit 101 is not limited to the video signal. For example, a digital broadcast signal (broadcast) such as a digitized audio signal, data broadcast, electronic program guide information, or network information can be used. Wave).

  The demodulator 102 demodulates the digital broadcast signal input to the RF receiver 101 and sends it to the decoder 103.

  The decoder 103 decomposes a demodulated signal such as MPEG2TS into a video component (signal) and an audio component (signal). 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 the audio signal has many formats, the audio processor 104 normally performs the decoding process of the audio signal. 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 a form of a television provided with the display unit 112 and the speaker 105, the present invention is not limited to this. For example, in the case of a BD (BluRay) recorder or an STB (Set Top Box), Instead of the speaker 105, an audio signal may be output to an external device.

  Remote control communication unit 106 receives a control signal from a remote control (not shown). Examples of the remote controller 9 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 compressed data (for example, MPEG4).

  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 once sent to the graphic memory 110 via the decoder 103. Note that there is no essential difference in the video signal output to the graphic memory 110 depending on whether or not it 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 the display data include data broadcasting, data such as OSD (on-screen display) data, and setting menus. The graphic memory 110 includes a plurality of planes, and each plane can be superimposed or alpha blended.

  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. For example, a Bluetooth wireless keyboard or a wireless mouse can be used as the input unit 201.

  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 inserting only 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 in a format such as HDMI. The audio signal is also transmitted 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 Disk), a DVD (Digital Video Disk), 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, a photo, a slide show, a word processing document, or a game.

(Process to display video clearly)
Next, processing for clearly displaying the video signal of the PC content in the television 1 with a built-in PC according to the present embodiment will be described with reference to FIGS. In addition, the referential mark of each member in this clause shall be based on FIG. 1 or FIG.

  FIG. 4A is a diagram in which the PC content is displayed on the display 2 as it is. As shown in this figure, when the PC content is displayed as it is, the video is scaled. For this reason, display quality deteriorates.

  Therefore, the content synthesizing unit 14 of the TV unit 10 generates a TV broadcast program “Takeke Tochigi” shown in FIG. A composite content, that is, a display video is generated by so-called dot-by-dot so that one pixel of the video in the “baseball game” corresponds to one dot of the display 2. Then, as shown in FIG. 4B, the video output unit 11 outputs the video generated by the content synthesis unit 14 to the display 2. As a result, it is possible to prevent jaggies or moire due to scaling or the like even in a video for which display quality is not desired to be degraded, for example, a game video or a video distribution video, and display can be performed without reducing the display quality. Further, since only one image of the window in which the PC content is desired to be viewed is displayed with one pixel corresponding to one dot of the display 2, only a relatively small area on the display 2 may be used for the PC content. Therefore, the TV broadcast program generated by the TV unit 10 can be viewed. Further, the PC content can be displayed on the display 2 in a PinP (picture-in-picture) format.

  Next, another example in which the video signal of the PC content is clearly displayed will be described with reference to FIG. In this case, the content composition unit 14 is processing when the resolution of the PC content is lower than the resolution of the television broadcast program. FIG. 5A is a diagram in which a video signal of PC content with a resolution of 1280 × 1024 is scaled and displayed on the display 2 with a resolution of 1920 × 1080. As an example of a resolution of 1920 × 1080, for example, full-spec high vision can be considered. As shown in this figure, if the video signal of the PC content is scaled and displayed as it is, the display quality is deteriorated.

  Therefore, the content composition unit 14 generates a display video so that one pixel of the video signal in the entire PC content video “baseball game” corresponds to one dot of the display 2. Then, the content composition unit 14 generates a display video so as to display the television broadcast program “Takeke Tochigi” in the margin portion of the display 2, that is, 640 × 56 pixels obtained by subtracting 1280 × 1024 from 1920 × 1080. . As a result, the entire video of the PC content and the TV broadcast program can be displayed simultaneously without degrading the display quality of the PC content. Also, the TV broadcast program does not hinder the display of the PC content video.

  Next, another example of clearly displaying the video signal of the PC content will be described with reference to FIG. As shown in this figure, the content synthesizing unit 14 generates a display video so that one pixel of the video signal in the entire PC content video “baseball game” corresponds to one dot of the display 2. Then, the content synthesizing unit 14 generates a display video so as to display the entire TV broadcast program “Takeke Tochigi”. As a result, the user can view the entire PC content video and the entire television broadcast program on one screen.

  As described above, in the TV 1 with a built-in PC, a display video is generated so that one pixel of the video signal of the PC content corresponds to one dot of the display 2. Therefore, it is possible to prevent jaggies or moire due to scaling or the like and to clearly see the PC content. In addition, a TV broadcast program can be viewed simultaneously on the same screen.

  FIG. 6A is a diagram showing a case where the PC content and the television broadcast program are generally divided into two screens and displayed. As shown in this figure, when displaying two screens equally divided, a display video cannot be generated so that one pixel of the video signal of the PC content corresponds to one dot of the display 2 There is. Accordingly, the display quality deteriorates because it is necessary to perform scaling display.

  Therefore, the content synthesizing unit 14 of the PC built-in television 1 may change the layout, that is, reduce the screen of the PC content to generate the synthesized content, that is, the display video. Accordingly, as shown in FIG. 6B, the PC built-in television 1 can simultaneously display the PC content and the television broadcast program without degrading the display quality of the PC content.

  In the above-described example, the display video is generated so that one pixel of the video signal of the PC content corresponds to one dot of the display 2. However, the content synthesizing unit 14 generates a display video so that one pixel of the video signal of the PC content corresponds to a plurality of dots of the display 2 and a plurality of pixels correspond to one dot of the display 2. May be.

(Example of flow of screen display processing)

FIG. 7 is a sequence diagram showing an example of the flow of information processing when displaying the full TV screen and the PC screen on the PC built-in television 1 of the present invention.

  As a precondition before the processing of FIG. 7 starts, the TV unit 10 has received and decoded a broadcast wave from a broadcast station and acquired a broadcast program in advance. In addition, various types of broadcast-related information are received as needed in accordance with the reception of broadcast waves. Examples of broadcast-related information include data broadcasting, electronic program guides, subtitles, closed captions, information from the network, information indicating the channel currently being viewed, information indicating the user's residential area, and the like.

  In the sequence of FIG. 7, the TV unit 10 first displays the TV main screen (step S1). Next, the user inputs a PC display command using the remote controller 9 (step S2). Based on this input, the TV unit 10 requests PC content 20 from the PC unit 20 (step S3). The PC unit 20 transfers the received request to the service server (external device) (step S4). The service server transmits the content to the PC unit 20, which is received by the PC unit 20 (step S5). The PC unit 20 transfers the received content to the TV unit 10 (step S6).

  Here, the user uses the remote controller 9 to select the PC content display method in any of FIGS. 4 to 6 (step S7). Note that the TV unit 10 may automatically select the PC content display method according to the PC content.

  Next, the content synthesizing unit 14 of the TV unit 10 causes one pixel of the video signal of the PC content to correspond to one dot of the display 2 by any one of the methods described in FIGS. 4 to 6 selected by the user. A composite video is generated (step S8). Then, the video output unit 11 of the TV unit 10 displays the received video on the display 2 (step S9).
