Abstract
본 발명은 자동채널설정방법에 관한 것으로서, 설정한 방송채널이 마지막 유효채널이라고 알리는 ID신호를 검출할 경우에 자동으로 서치모드(search mode)에서 스킵모드(skip mode)로 전환하고, 동시에 모든 유효채널이 메모리 되었고 스킵모드가 실행되었음을 알리는 OSD문자 또는 도형을 CRT화면상에 나타나게 하는 텔레비전수상기의 마지막 채널메모리시 스킵모드로의 자동전환방법에 관한 것이다.The present invention relates to an automatic channel setting method, which automatically switches from search mode to skip mode and detects all valid signals upon detecting an ID signal indicating that the set broadcast channel is the last valid channel. The present invention relates to a method for automatically switching to a skip mode in the last channel memory of a television receiver, which displays an OSD text or a figure indicating that a channel is memorized and a skip mode is executed.
본 발명은 동기신호검출부(19)와, 마지막 채널임을 알리는 ID 신호를 검출하는 ID 신호검출부(30)를 구비하여, 자동채널설정의 채널서치모드인 경우에 동기신호검출부(19)로 부터의 신호에 의해서 서치하는 채널의 IF 신호에 동기신호가 포함된 지를 판단하여 동기신호가 있는 유효채널인 경우에 이를 채널메모리(10)에 메모리하고, 튜너(100)를 제어하여 서치하는 채널을 한 단계 업 시키며, ID 신호검출부(30)로 부터의 신호에 의해서 방송신호에 마지막 채널임을 알리는 ID 신호가 있는지를 판단하여, 방송신호에 마지막 채널임을 알리는 ID 신호가 있는 경우에 채널서치모드에서 스킵모드로 자동전환하는 것을 특징으로 한다.The present invention comprises a synchronization signal detection unit (19) and an ID signal detection unit (30) for detecting an ID signal indicating the last channel, and the signal from the synchronization signal detection unit (19) in the channel search mode of automatic channel setting. It is determined whether the synchronization signal is included in the IF signal of the channel to be searched by and stored in the channel memory 10 in the case of an effective channel having the synchronization signal, and the tuner 100 is controlled to increase the search channel by one step. The ID signal detecting unit 30 determines whether there is an ID signal indicating that the broadcast channel is the last channel, and when there is an ID signal indicating that the broadcast channel is the last channel, the channel search mode automatically skips to the skip mode. It is characterized by switching.
