Abstract

본 발명은 신호강도 적응방식의 텔레비전 태널서치장치와 그 방법에 관한 것으로, 기능설정수단에서 해당 텔레비전에서 시청가능한 채널의 고속서치모드를 설정하고, 그 고속채널서치모드가 설정된 상태에서 제어수단으로부터 튜너에 대해 채널선국신호를 제공하고 그 채널선국신호에 따라 선국되어 IF모듈에서 처리되는 방송신호레벨의 세기를 신호검출수단에서 검출하여 그 검출된 방송신호레벨의 세기에 기초하여 그 텔레비전에 의해 시청가능한 방송국의 채널을 신호강도에 기초하여 분류하고, 그 분류된 채널을 채널메모리에 저장하여 신호레벨에 따라 시청가능한 방송채널의 고속서치가 행해지도록 한 것이다.The present invention relates to a television channel search apparatus of a signal strength adaptation method and a method thereof, wherein the function setting means sets a high-speed search mode of a channel that can be watched on the television, and the tuner is tuned from the control means while the high-speed channel search mode is set. Provides a channel tuning signal for the channel, and detects the strength of the broadcast signal level which is tuned according to the channel tuning signal and processed by the IF module, and is viewable by the television based on the detected broadcast signal level. Channels of broadcast stations are classified based on signal strength, and the classified channels are stored in a channel memory so that high-speed search of a broadcast channel that can be viewed according to signal level is performed.
