Abstract

본 발명은 예약녹화시 동일한 방송 프로그램이 여러 채널에서 동시에 수신되는 경우, 이들 동일 방송신호 가운데 신호상태가 가장 좋은 채널의 방송신호를 자동으로 선국하여 녹화할 수 있도록 된 텔레비디오에 관한 것으로, 예약녹화를 위한 튜너(TUNER)와, 이 튜너에 의해 선국된 방송신호를 녹화하는 데크(DECK), 및 녹화예약된 프로그램에 대한 정보데이터를 저장하는 예약녹화설정부를 구비한 텔레비디오(TVCR)에 있어서; 상기 튜너로부터 출력되는 영상신호의 레벨을 근거로 튜너 내부의 증폭도를 제어함으로써 영상신호의 출력레벨을 일정하게 제어하는 AGC회로와, 이 AGC회로로부터 출력되는 아날로그 형태의 AGC신호를 디지탈신호로 변환 출력하는 A/D변환기, 상기 튜너에 의해 선국되는 방송채널에 대해 각 채널별 AGC레벨을 해당 채널데이터에 대응시켜 저장하는 AGC레벨저장부, 상기 튜너에서 출력되는 방송신호로부터 KBPS코드신호를 분리하여 검출하는 KBPS디코더부, 및 상기 예약녹화설정부에 저장되어 있는 데이터를 근거로 상기 튜너를 제어함으로써 예약설정된 프로그램을 검색함과 더불어 검색결과 상기 AGC레벨저장부에 저장되게 되는 데이터를 비교연산하여 AGC레벨이 최소인 방송채널을 선국하도록 제어하는 제어부를 포함하여 구성된 것을 특징으로 한다.The present invention relates to a tele-video which is capable of automatically tuning and recording a broadcast signal of a channel having the best signal state among the same broadcast signals when the same broadcast program is simultaneously received in multiple channels during reservation recording. A televideo (TVCR) having a tuner (TUNER), a deck for recording broadcast signals tuned by the tuner, and a reservation recording setting section for storing information data on a program reserved for recording; An AGC circuit that constantly controls the output level of the video signal by controlling the amplification degree inside the tuner based on the level of the video signal output from the tuner, and converts and outputs an analog AGC signal output from the AGC circuit into a digital signal. An A / D converter, an AGC level storage unit for storing the AGC level for each channel corresponding to the channel data for the broadcast channel selected by the tuner, and separating and detecting a KBPS code signal from the broadcast signal output from the tuner. The tuner controls the tuner based on the data stored in the KBPS decoder unit and the reserved recording setting unit. And a control unit for controlling to tune to this minimum broadcast channel.
