Abstract
본 발명은 키입력부조작시 OSD 문자 또는 도형이 CRT 화면상에 나타나는 텔레비전수상기에 관한 것으로서, 특히 영상 및 음성이 출력되지 않는 무신호상태에서 키입력부를 조작할 때 TV의 화면상에 나타나는 OSD문자 또는 도형의 식별을 보다 용이하게 되도록 배경용 OSD을 화면상에 나타나게 하는 텔레비전수상기의 무신호상태에서의 OSD 동작시 화면처리방법에 관한 것이다.The present invention relates to a television receiver in which OSD characters or figures appear on a CRT screen during key input operation, and in particular, OSD characters appearing on a screen of a TV when the key input unit is operated in a non-signal state where video and audio are not output. The present invention relates to a screen processing method during an OSD operation in the no signal state of a television receiver, which makes the background OSD appear on the screen so that the figure is more easily identified.
본 발명의 무신호상태에서의 OSD 동작시 화면처리방법은 키입력부(9)로부터 신호가 입력될 경우에 동기신호검출부(20)로부터의 신호에 의해서 영상신호에 동기신호가 포함되었는지를 판단하여, 동기신호가 없는 무신호상태인 경우에 OSD 발생부(12)를 제어하여 배경용 OSD에 대응하는 R. G. B 신호 및 OSD 블랭킹신호(Y′)를 출력토록 하고, 상기 동기신호검출부(20)로부터의 신호에 의해서 영상신호에 동기신호가 포함되었는지를 다시 판단하여, 영상신호에 동기신호가 포함된 경우에 OSD 발생부(12)를 제어하여 배경용 OSD에 대응하는 R, G, B 신호 및 OSD 블랭킹신호(Y′)의 출력을 중지하여 정상적인 영상이 화면에 나타나도록 하는 것을 특징으로 한다.In the OSD operation in the no-signal state of the present invention, when a signal is input from the key input unit 9, it is determined whether the synchronization signal is included in the video signal by the signal from the synchronization signal detection unit 20. In the case of no signal state without a synchronization signal, the OSD generator 12 is controlled to output an RG B signal and an OSD blanking signal Y ′ corresponding to the background OSD, and output from the synchronization signal detection unit 20. It is judged again whether the sync signal is included in the video signal by the signal, and when the sync signal is included in the video signal, the OSD generator 12 is controlled to correspond to the R, G, B signals and OSD blanking corresponding to the background OSD. The output of the signal Y 'is stopped so that a normal image is displayed on the screen.
