Abstract

본 발명은 화상기능이 구비된 텔레비전에 관한 것으로, 텔레비전 송화자를 촬상하여 비디오신호로 엔코딩하고, 음성신호를 디지털로 변환하는 촬상수단(10); 상기 촬상수단(10)의 출력을 고속전송망으로 전송하기 위하여 변조하는 변조수단(21); 상기 변조수단(21)의 출력을 고속 공중망으로 인터페이스하고, 고속 공중망으로부터 입력된 상대방의 신호를 수신단으로 전달하는 통신망 인터페이스부(22); 수신된 상대방의 신호를 복조하여 영상신호와 오디오신호를 재생하는 복조수단(27); 복조된 영상신호와 오디오신호를 텔레비전의 IF신호로 변환하는 IF신호변환기(28); 상대방을 호출하기 위한 DTMF신호를 발생하는 FTMF발생기(26); 리모콘의 키입력에 따라 전화번호를 송출하도록 상기 DTMF발생기(26)를 제어하고, 화상전화모드시 수신된 IF신호를 선택하도록 스위칭IC(29)를 제어하는 마이콤(25)이 구비되어 리모콘의 키입력에 따라 화상전화모드에서는 화상전화기능을 처리할 수 있다.The present invention relates to a television having an image function, comprising: imaging means (10) for imaging a television caller, encoding it into a video signal, and converting an audio signal into digital; Modulation means (21) for modulating the output of the imaging means (10) for transmission to a high speed transmission network; A communication network interface unit 22 for interfacing the output of the modulation means 21 to a high-speed public network and transmitting a signal of the other party inputted from the high-speed public network to a receiving end; Demodulation means (27) for demodulating the received signal of the other party to reproduce the video signal and the audio signal; An IF signal converter 28 for converting demodulated video signals and audio signals into IF signals of a television; An FTMF generator 26 for generating a DTMF signal for calling the other party; A microcomputer 25 for controlling the DTMF generator 26 to transmit a telephone number according to a key input of a remote controller and a switching IC 29 for selecting an IF signal received in a video telephone mode is provided. According to the input, the video telephone function can be processed in the video telephone mode.
