Abstract

본 발명은 TV수상기의 방송무신호 채널선국시 음성제어장치에 관한 것으로, TV수상기의 특정채널 시청시에 타방송채널을 확인코자 할 경우에는 리모콘 장치의 조작에 의해 채널을 직접 선국할시에 방송화면이 출력되지 않아도 이를 화면상에 송상하였던 바, 이로 인해 초기에 시청하던 화면을 연속 시청할 수 없는 문제점이 있었다.The present invention relates to a voice control apparatus for channelless signal channel selection of a TV receiver, and to broadcast a channel when a channel is directly tuned by the operation of a remote control device in order to check another broadcasting channel when watching a specific channel of the TV receiver. Even though the screen was not output, it was remitted to the screen. As a result, there was a problem in that the screen that was initially viewed cannot be continuously viewed.

따라서, 본 발명에 의하면, 튜너에 의해 선국된 방송화면을 시청하고 있는 상태에서, 사용자가 타방송사의 채널을 직접 선국할 경우 선국된 방송채널에 대한 동기신호 여부를 판별하여 동기신호가 검출되면, 선국된 채널로 절환되고 그렇지 않을 경우에는 선국되기 전의 방송에 대한 음성신호와 OSD문자로서 방송무신호임을 출력하여 사용자의 오동작을 방지케 하면서 채널절환에 대한 편의를 제공하게 된 발명인 것이다.Therefore, according to the present invention, when the user directly tunes to a channel of another broadcaster while watching a broadcast screen tuned by a tuner, if the sync signal is detected by determining whether or not a sync signal is detected for the tuned broadcast channel, If the channel is switched to the tuned channel, otherwise, the voice signal and the OSD text for the broadcast before the broadcast is outputted as a non-signal to prevent the malfunction of the user while providing convenience for channel switching.

Claims

In the control unit which controls the overall operation of the apparatus when receiving the airwaves and allowing the broadcast signal to be tuned by the tuner, and the television receiver to watch TV based on a predetermined control signal from the control unit, the tuner 10 When the channel is switched by the direct channel selection of the remote control device 90 during the TV viewing, in step 101 of being tuned, and transmitting the same to the CRT 51 through the image processing unit 50 to the TV viewing. (102) When the synchronization signal is detected by the microcomputer 100 for the tuned channel (103), when the synchronization signal is detected, the channel is switched to the tuned channel through the tuner 10, but the synchronization signal If is not detected, it is characterized in that it is implemented in the operation procedure of outputting a voice signal for the broadcast channel prior to the tuning (104), and outputting a display character for the broadcast no signal (105) TV number to say Voice control device when no broadcasting signal of the channel selection group.
