Abstract
본 발명은 주화면을 통해 화면시청중 부화면에서 채널을 탐색시 무신호일 경우 다음 채널을 탐색하고 주화면과 부화면의 채널이 동일할 경우 스킵(Skip)하여 채널탐색속도 및 탐색효율을 향상시키도록 한 부호면을 통한 채널 탐색방법에 관한 것으로, 종래 채널 탐색장치는 사용자가 키이매트릭스부(7)의 자동채널설정 키이신호를 선택하면, 마이컴(1)은 부화면을 온하여 부화면 튜너부(2)에서 선국된 방송신호를 1채널씩 튜닝하여 방송신호가 있는 채널데이타를 메모리부(8)에 저장할때 에러등에 의해 신호가 좋지않은 채널이 저장되여 채널탐색시 메모리부(8)에 저장된 채널 1채널씩 모두 튜닝되므로 신호가 좋지 않은 채널 및 무신호 채널도 탐색하게되므로 채널탐색속도 및 탐색효율이 저하되는 문제점이 있었다.According to the present invention, when searching for a channel in a sub-screen while viewing a screen through a main screen, the next channel is searched and a channel is skipped when the channels of the main screen and a sub-screen are the same to improve channel search speed and search efficiency. In the conventional channel search apparatus, when the user selects the automatic channel setting key signal of the key matrix unit 7, the microcomputer 1 turns on the sub-screen to display the sub-screen tuner unit. When tuning the broadcast signal tuned in step (2) by one channel and storing the channel data with the broadcast signal in the memory unit 8, a channel having a bad signal due to an error or the like is stored and stored in the memory unit 8 during channel search. Since all channels are tuned one by one, there is a problem that the channel search speed and the search efficiency are deteriorated because the signal is searched for the channel with no signal and the no signal channel.
본 발명은 이와같은 종래 문제점을 해결하기 위하여 자동채널설정 키이신호가 입력되어 부화면 튜너부에 선곡된 방송신호의 채널을 메모리부에 저장할때 부화면 튜너부에서 선국된 방송신호의 영상을 동기분리부가 동기분리하여 방송신호가 있는 채널만을 메모리부에 저장시키므로써 채널탐색시 마이컴은 메모리에 저장된 임의의 채널데이터와 현재 주화면에 튜닝된 채널데이타를 비교하여 동일한 채널일 경우 메모리에 저장된 다음 채널데이타가 탐색되도록 스킵하고, 메모리부에서 현재 튜닝된 채널이 무신호일 경우 빨리 다음채널이 탐색되도록 하므로서 채널탐색속도 및 탐색효율이 향상되도록 한 것으로, 방송채널 탐색에 적용한다.In order to solve the conventional problems, the present invention is to synchronize the video of the broadcast signal selected by the sub-screen tuner when the channel of the broadcast signal selected by the automatic channel setting key signal is stored in the memory unit. By additionally separating and storing only channels with broadcast signals in the memory unit, when searching for channels, the microcomputer compares the channel data stored in the memory with the channel data tuned in the current main screen. Is skipped, and when the channel currently tuned in the memory unit is no signal, the next channel is searched quickly, thereby improving channel search speed and search efficiency.
