Abstract

본 발명은 소정 채널을 기억 또는 삭제시키고자 하는 경우 OSD신호를 반블랭킹처리하여 디스플레이하므로써 간섭채널 또는 무신호채널에 의한 번쩍거림을 순화시키며, 해당 채널의 신호 상태를 대략 확인할 수 있도록 한 채널기억/지움모드에서의 OSD 신호 블랭킹처리제어방법을 제공한다.According to the present invention, when the user wants to memorize or delete a predetermined channel, the OSD signal is semi-blanked and displayed to smooth the flashing caused by the interference channel or the non-signal channel, and the channel memory / single can be roughly checked. An OSD signal blanking process control method in erase mode is provided.

본 발명은 튜너(10)에 의해 선국되는 소정 채널의 방송신호로 부터 영상과 음성을 재생하는 기본기능과 함께 약정된 복수개의 기능키의 입력에 의해 부가기능을 수행할 수 있도록 된 텔레비젼에 있어서, 상기 튜너(10)가 선국한 채널을 상위채널 또는 하위채널로 변경 시키기 위해 키입력하는 단계와, 상기 키입력에 의한 해당 채널을 선국하는 단계와, 상기 선국되는 채널의 영상신호로부터 동기신호가 검출되는지를 판단하는 단계와, 상기 동기신호가 검출되면 그에 따른 영상신호가 화면상에서 정지화상으로 디스플레이되는지를 판단하는 단계와, 상기 동기신호가 검출되지 않거나 상기 정지화상인 경우에는 화면상에 기설정된 OSD색 신호를 반블랭킹하여 디스플레이하는 단계, 및 상기 선국중인 채널을 기억시키거나 지우는 단계를 구비하여 이루어진 것을 특징으로 한다.The present invention provides a television in which a supplementary function can be performed by inputting a plurality of contracted function keys together with a basic function of reproducing video and audio from a broadcast signal of a predetermined channel tuned by the tuner 10. Key input to change the channel tuned by the tuner 10 to an upper channel or a lower channel, tuning the corresponding channel by the key input, and detecting a synchronization signal from an image signal of the tuned channel. Determining whether the video signal is displayed as a still picture on the screen when the sync signal is detected; and if the sync signal is not detected or the still picture, a preset OSD on the screen. Semi-blanking and displaying a color signal, and storing or erasing the channel being tuned. It is characterized by.
