Abstract

본 발명은 유선방송 수신기 데이터 송수신 방법에 관해 게시한다. 본 발명은 케이블에서 입력되는 신호를 선국하는 튜너부와, 상기 튜너부의 출력을 입력으로하여 선국된 채널의 영상을 검파하는 PIF부와, 상기 PIF부의 출력을 입력으로하여 정합부로 인가되는인밴드 신호의 데이터를 추출하여 추출된 신호를 출력하는 선택부, 상기 선택부의 출력을 입력으로하여 조건에 따라서 튜너부를 제어하고, 모뎀부를 제어하는 제어부, 상기 제어부의 제어에 의하여 신호를 케이블로 송신하는 모뎀부로 구성되는 정합부로 구성되어서 FSK 모뎀의 수신 회로 및 구성이 불필요하지만 쌍방향 통신이 가능하기 때문에 생산성이 증대되고, 수신채널이 불필요하므로 새로운 방송채널의 운영이 가능하며, 수신단 발진 신호원의 제거로 인하여 수신기 화질 열화가 개선되는 것이다.The present invention relates to a method of transmitting and receiving data of a wired broadcast receiver. A PIF unit for detecting an image of a channel selected by inputting an output of the tuner unit; and an in-band signal receiving unit for receiving an output of the PIF unit as an input, A control unit for controlling the tuner unit according to the condition and receiving the output of the selection unit and controlling the modem unit; and a modem unit for transmitting the signal through a cable under the control of the control unit Since the receiving circuit and the configuration of the FSK modem are unnecessary, bidirectional communication is possible. Therefore, productivity is increased and a receiving channel is unnecessary. Therefore, a new broadcasting channel can be operated, The deterioration of image quality is improved.
