Abstract
본 발명은 브이시알 초기화 단계에서 텔레비전과의 RF 매칭을 위한 테스트바 영상을 별도의 스위치 조작없이 자동으로 발생되게 하는 기술을 제안한다.The present invention proposes a technique for automatically generating a test bar image for RF matching with a television in a VSI initialization step without a separate switch operation.
이를 위한 본 발명은 브이시알과 텔레비전전전전과의 RF 매칭 실행 초기화 여부를 판단하기 위해 브이시알의 플러그 인에 의한 최초 파워 온 모드를 인식하는 단계와, 상기 단계에서 브이시알 파워 온 상태가 인식되면 재생모드 키 입력이 있는가를 판단하는 단계와, 상기 단계에서 재생모드이면 테스트 신호 발생 실행을 디스에이블하고 재생모드가 아니면 OSD 제어부에 의한 테스트바 형태의 화상이 텔레비전전전의 화면에 출력되도록 테스트바 영상 신호 대응 테스트 신호를 발생하는 단계와, 상기 OSD 방식으로 만들어진 테스트바 영상 신호를RF 신호로 변환하여 텔레비전전의 안테나 단으로 전송하는 단계와, 상기의 테스트바 영상 신호를 이용한 텔레비전젼과 브이시알과의 RF 매칭 조정 이후 매칭 완료를 판단하고 테스트바 영상 신호를 해제시키는 단계를 포함한다.To this end, the present invention is to recognize the initial power-on mode by the plug-in of Vial to determine whether or not to initialize the RF matching between the Vial and the television war, and when the Vialal power on state is recognized in the step Determining whether there is a mode key input and disabling the execution of the test signal generation in the reproducing mode. If the reproducing mode is not in the reproducing mode, the test bar image signal is output so that the image of the test bar by the OSD controller is output on the screen before television. Generating a test signal, converting a test bar image signal generated by the OSD method into an RF signal and transmitting the RF signal to an antenna stage before the television; and RF matching between the television image and the VSI using the test bar image signal. After adjusting, it determines matching completion and releases test bar video signal. And a system.
이러한 본 발명은 테스트바 선택 스위치의 삭제에 따른 원가 절감 효과와 브이시알 초기화시에 텔레비전전과의 RF 매칭 작업이 편리하고 정확하게 실행된다.In the present invention, the cost reduction effect of the deletion of the test bar selection switch and the RF matching operation before the television at the time of VSI initialization are performed conveniently and accurately.
