Predetermined digital signal processing is performed and output to the graphic processing unit 54 and the audio processing unit 55.

  Among these, the graphic processing unit 54 has a function of superimposing and outputting the OSD signal generated by the OSD (On Screen Display) signal generation unit 57 on the digital video signal supplied from the signal processing unit 47. The graphic processing unit 54 selectively outputs the output video signal of the signal processing unit 47 and the OSD signal which is the output of the OSD signal generation unit 57, and both outputs constitute half of the screen. Can be combined and output.

  The digital video signal output from the graphic processing unit 54 is supplied to the video processing unit 58. The video processing unit 58 converts the input digital video signal into an analog video signal in a format that can be displayed on the video display 14 and outputs the analog video signal to the video display 14 for video display.

  The audio processing unit 55 converts the digital audio signal input from the signal processing unit 47 into an analog audio signal in a format that can be reproduced by the speaker 15, and outputs the analog audio signal to the speaker 15 for audio reproduction.

  Here, in the digital television broadcast receiving apparatus 11, all the operations including various receiving operations are comprehensively controlled by the control unit 61. The control unit 61 incorporates a CPU (Central Processing Unit) or the like and receives operation information from the operation unit 16 or receives operation information sent from the remote controller 17 via the light receiving unit 18. Each unit is controlled so that the operation content is reflected.

  In this case, the control unit 61 mainly includes a ROM (Read Only Memory) 62 that stores a control program executed by the CPU, a RAM (Random Access Memory) 63 that provides a work area to the CPU, and various setting information. And a nonvolatile memory 64 in which control information and the like are stored.

  The control unit 61 is connected to a card holder 66 in which the first memory card 19 can be mounted via a card I / F (Interface) 65. Accordingly, the control unit 61 can perform information transmission via the card I / F 65 and the first memory card 19 mounted on the card holder 66.

  Further, the control unit 61 is connected to a card holder 68 into which the second memory card 20 can be mounted via a card I / F 67. Thus, the control unit 61 can perform information transmission via the card I / F 67 with the second memory card 20 mounted in the card holder 68.

  The control unit 61 is connected to the first LAN terminal 21 via the communication I / F 69. Accordingly, the control unit 61 can perform information transmission with the LAN-compatible HDD connected to the first LAN terminal 21 via the communication I / F 69. In this case, the control unit 61 has a DHCP (Dynamic Host Configuration Protocol) server function, and assigns and controls an IP (Internet Protocol) address to a LAN-compatible HDD connected to the first LAN terminal 21.

  Further, the control unit 61 is connected to the second LAN terminal 22 via the communication I / F 70. Accordingly, the control unit 61 can perform information transmission with each device (for example, a personal computer, a portable terminal, a cellular phone, etc.) connected to the second LAN terminal 22 via the communication I / F 70.

  The remote control set 204 includes a remote control communication input / output unit 207 that realizes a two-way communication path with the television set 200, a video phone processing unit 206 that is connected to the remote control communication input / output unit 207 and has a video phone processing function, and the video phone processing unit 206. It has a connected display unit 205, audio output unit 208, audio input unit 210, and user input processing unit 209.

  The audio output unit 208 is for outputting the telephone voice processed by the videophone processing unit 206, and the display unit 205 displays the telephone image processed by the videophone processing unit 206. Of course, the display unit 205 is also used to display other processed images.

  The voice input unit 210 is a microphone for inputting a user's voice. The user input processing unit 209 performs telephone number and other user input processing. A signal for performing a videophone call is input to the videophone processing unit 206, and a signal for performing other functions is input to the remote control. Directly input to the output unit 207.

  The flow of processing after receiving a call will be described with reference to FIG.

  As shown in FIG. 4, an incoming call signal is input to the network interface unit 201 via the network. Next, the incoming call signal is notified to the videophone processing unit 202. When receiving the incoming call, the videophone processing unit 202 notifies the remote control set 204 via the remote control communication input / output unit 203.

  Next, remote control set 204 receives an incoming call notification via remote control communication input / output unit 207 and inputs it to videophone processing unit 206. When receiving the incoming call notification, the videophone processing unit 206 displays the incoming call on the display unit 205. If necessary, the voice output unit 208 generates an incoming call sound.

  Next, when the user inputs a response for reception, it is input to the user input processing unit 209, and in response to this, the videophone processing unit 206 outputs a reception response signal. This reception response is transmitted to an external caller via the remote control communication input / output unit 207 of the remote control set 204, the remote control communication input / output unit 203 of the television set 200, the videophone processing unit 202, and the network interface unit 201.

  After the line is thus opened, a videophone call can be made using the display unit 205, the audio output unit 208, the audio input unit 210, and the like of the remote control set 204.

  Next, FIG. 3 shows another embodiment of the present invention. The same parts are denoted by the same reference numerals as those in FIG.

  In this embodiment, the voice output unit 208 and the voice input unit 210 are omitted, and only the incoming call is displayed on the display unit 205. The response can be made by the videophone processing 202 installed in the television set 200, the video display unit 14, the audio output unit 15, or the audio input unit (not shown).

  Next, FIG. 5 shows another embodiment of the present invention. In this embodiment, a display unit 505 for a videophone is provided in a television set 510 separately from the image display unit 503 for a television.

  In addition, the television set 510 includes a network interface unit 500, a videophone processing unit 501, a power supply control unit 504, a TV main circuit unit 502, and a user input unit 506.

  In this television set with a videophone function 510, a videophone network interface unit 500, a videophone processing unit 501, a videophone display unit 505 for displaying the status of incoming calls, a TV main circuit 502, a video display unit 503, and the like. A power control unit 504 is provided so that power control is performed independently.

  In this way, for example, even when the power source of the TV set 510 is not turned on, the dedicated TV phone processing unit 501 and the TV phone display unit 505 are activated to use the TV phone function when an incoming call is received. Thus, it is not necessary to activate the main display unit 503 and the TV main circuit unit 502 of the TV function, and wasteful power consumption can be prevented.

  Note that the user processing unit 506 for performing power control may be provided in the television set 510 main body or in the remote control set.

  In addition, the remote control set may sound or vibrate instead of the incoming call display. In addition, the response method at the time of incoming call may be registered in advance in the videophone processing unit of the television set with the remote control set.
