Abstract

본 발명은 TV방송 무신호채널에서의 화면조정방지장치에 관한 것으로서,The present invention relates to a screen adjustment prevention device in a TV broadcasting no signal channel,

종래에는 TV방송 채널절환시에 절환된 채널이 방송무신호 채널임에도 불구하고, 사용자의 화면상태조정기능을 선택하여도 이를 화면상에 그대로 출력하였으나, 이는 사실상의 무의미한 기능인 바,Conventionally, although the channel switched during TV broadcasting channel switching is a broadcast non-signal channel, even when the user selects the screen condition adjusting function, the channel is output as it is, but this is a meaningless function.

본 발명에 의하면, 절환된 채널에 대하여 방송신호를 검출하여 이에 대하여 방송신호가 검출되지 않을시에, 사용자의 조작에 의해 화면상태 조정기능이 선택되면, 그 기능을 실행시키지 않으면서, 그에 대한 경고문구를 화면상에 출력되게 함으로써, 사용자의 방송무신호 채널 변경에 대한 후속조치를 취할 수 있게한 발명인 것이다.According to the present invention, when a screen state adjustment function is selected by a user's operation when a broadcast signal is detected for a switched channel and a broadcast signal is not detected, the warning is not performed without executing the function. By presenting the text on the screen, it is an invention that can take a follow-up action to change the user's broadcast-free signal channel.
