Abstract
본 발명은 OSD(on screen display)기능을 구비한 텔레비전 수상기에 관한 것으로서, 특히 수상기의 A/V(audio/video)단자, 즉 외부입력단자에 VCR을 연결한 경우에 시청자가 VCR의 비디오를 시청할 때 비디오테이프를 집어 넣고 VCR을 플레이시키면 시청자가 A/V선태기를 누르지 않더라도 자동으로 VCR모드로 전환되도록 하는 텔레비젼수상기의 VCR플레이시 VCR모드로의 자동전환방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver having an OSD (on screen display) function. In particular, when a VCR is connected to an A / V (audio / video) terminal of the receiver, that is, an external input terminal, a viewer can watch a video of the VCR. The present invention relates to a method for automatically switching to a VCR mode during a VCR playback of a television receiver, when the video tape is inserted and the VCR is played, thereby automatically switching to the VCR mode even when the viewer does not press the A / V selector.
본 발명의 VCR 플레이시 VCR모드로의 자동전환방법은 외부입력단자에 연결된 동기신호검출부(26)를 구비하여, 동기신호검충부(26)로부터의 신호에 의거하여 동기신호가 검출되는지를 판단하여, 동기신호가 검출되지 않을 경우에 TV의 영상신호와 음성신호를 영상처리부(23)와 음성처리부(21)로 출력토록 하고, 다시 동기신호검출부(26)로부터의 신호에 의거하여 동기신호가 검출되는지를 판단하여, 동기신호가 검출될 경우에 OSD 발생부(12)를 제어하여 VCR모드로 자동전환된다는 안내문에 대응하는 R, G, B신호 및 OSD 블랭킹신보(Y′)를 출력토록 하고, 이어서 스위칭부(20)를 제어하여 VCR(19)로부터의 영상신호와 음성신호를 영상처리부(23)와 음성처리부(21)로 출력토록 하는 것을 특징으로 한다.The automatic switching method of the VCR mode to the VCR mode of the present invention includes a synchronization signal detector 26 connected to an external input terminal, and determines whether a synchronization signal is detected based on a signal from the synchronization signal detector 26. When the synchronous signal is not detected, the video signal and the audio signal of the TV are outputted to the image processing unit 23 and the audio processing unit 21, and the synchronous signal is detected based on the signal from the synchronous signal detection unit 26 again. When the synchronization signal is detected, the OSD control unit 12 controls the OSD generating unit 12 to output the R, G, and B signals and the OSD blanking signal Y 'corresponding to the notice of automatic switching to the VCR mode. Subsequently, the switching unit 20 is controlled to output the video signal and the audio signal from the VCR 19 to the image processing unit 23 and the audio processing unit 21.
