Television receiver with a TV phone function
First Claim
1. A television receiver with video telephone function for receiving a digital broadcast program signal and for transmitting and receiving a video telephone signal to and from another television receiver with video telephone function to thereby perform videophone communication, said television receiver comprising:
- a decoder being adapted to decode the received digital broadcast program signal and the video telephone signal;
a display panel being adapted to display a video image upon receipt of a video signal decoded by said decoder and supplied therefrom;
a speaker to which an audio signal decoded by said decoder is supplied;
a camera;
a microphone; and
an encoder being adapted to encode output signals of the camera and the microphone and for generating-a video telephone signal to be transmitted for the videophone communication, whereinwhen the videophone communication is started upon receiving an inbound videophone call from another communication device in the middle of outputting by the display panel and speaker the received digital broadcast program signal in a form of video and audio, the display panel and speaker output the video telephone signal received using the video telephone function, andwhen the videophone communication is finished, the display panel and speaker stop outputting the video telephone signal received using the video telephone function and output the received digital broadcast program signal.

Abstract
A videophone system includes a processor which selectively sets a television (TV) broadcast program viewing function mode and videophone function mode in response to manual operation of a remote control, a decoder which performs, in the TV program view mode, a TV program-use decode function for decoding a broadcast program signal received from a TV tuner to thereby display it on a display screen while producing audio sounds by loudspeakers and which performs, in the videophone function mode a videophone-use decode function for decoding a videophone signal received from a distant party to thereby display on the screen an image of the distant party using the screen and speakers, and an encoder which performs a videophone-use encode function for encoding a video signal from a camera and a voice signal from a microphone to generate a videophone signal, which is sent to the distant party via a network.

2. A digital information signal receiving and transmitting apparatus comprising:
-
a digital information signal receiver which receives a first digital information signal including a first video signal and a first audio signal; a videophone communicator which receives a second digital information signal including a second video signal and a second audio signal from other communication apparatus via a network and which transmits a third digital information signal including a third video signal and a third audio signal to the other apparatus; an output unit which outputs the first video signal and the first audio signal received by the digital information signal receiver and the second video signal and the second audio signal received by the videophone communicator; and a controller which controls the digital information signal receiver, the videophone communicator, and the output unit, wherein when the videophone communication is started upon receiving, from the other communication apparatus, an inbound videophone call in the middle of outputting, by the output unit the first digital information signal received by the digital information signal receiver, the output unit outputs the second digital information signal received by the videophone communicator, and when the videophone communication is finished, the output unit stops outputting the second digital information signal received by the videophone communicator and outputs the first digital information signal received by the digital information signal receiver. - View Dependent Claims (3, 4, 5, 6, 7)
