가전기기의 자동 튜닝 회로에 있어서, 입력 복합 영상 신호로부터 동기 신호를 검출하는 제1수단과, 튜닝에 의해 방송 신호를 수신하는 제2수단과, 온 타임 설정에 따라 파워 오프전 튜닝 데이타 유무에 의해 튜닝하고 상기 제1수단의 동기 검출 출력으로 부터 동기 검출이 없을시 튜닝 제어값을 증가시켜 튜닝하는 제3수단으로 구성됨을 특징으로 하는 텔레비젼 수상기의 자동 튜닝장치.An automatic tuning circuit of a home appliance, comprising: first means for detecting a synchronization signal from an input composite video signal, second means for receiving a broadcast signal by tuning, and presence or absence of tuning data before power-off in accordance with the on-time setting And third means for tuning and tuning by increasing the tuning control value when there is no synchronization detection from the synchronization detection output of said first means. 가전기기의 자동 튜닝 방법에 있어서, 온 타임이 설정되었을시 파워 오프전 튜닝데이타가 있는가를 체킹하는 제1과정과, 상기 제1과정에서 파워 오프전 튜닝 데이타가 없으면 튜닝 데이타 저장 영역을 클리어하고 튜닝 데이타가 있을시 이 값으로 튜닝하는 방송 신호를 수신하는 제2과정과, 상기 제2과정의 방송 신호의 수신에 따라 영상 신호의 동기 신호를 검출하는 제3과정과, 상기 제3과정에서 동기 신호가 검출되지 않을시 채널 변환용 튜닝 데이타 값을 증가시키는 제4과정과, 상기 제4과정에서 튜닝데이타 값이 소정 범위를 벗어 났으면 이전 튜닝 데이타를 초기화시키고 상기 튜닝데이타가 소정 범위내에 있으면 초기 튜닝 데이타와 같은가를 비교하여 같으면 온 타임 설정을 재세팅하고 같지 않으면 튜닝을 하여 방송 신호를 수신하는 제5과정으로 이루어짐을 특징으로 하는 텔레비젼 수상기의 자동 튜닝방법.In the automatic tuning method of home appliances, the first step of checking whether there is tuning data before power-off when the on time is set, and the tuning data storage area is cleared if there is no tuning data before power-off in the first step. A second process of receiving a broadcast signal tuned to this value when there is a second process, a third process of detecting a sync signal of an image signal according to the reception of the broadcast signal of the second process, and a sync signal at the third process A fourth step of increasing the channel data tuning data value if not detected; initializing the previous tuning data if the tuning data value is out of a predetermined range in the fourth step; and initial tuning data if the tuning data is within the predetermined range. If the comparison is the same, if it is the same, reset the on-time setting and if it is not the same, tune to receive the broadcast signal. Automatic tuning method of a television receiver characterized in that made. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
