Abstract
본 발명은 영상시스템에 있어서 양방향 전송제어가능한 영상신호 전송처리장치에 관한 것으로, 특히 복합 영상신호의 소정의 영역을 이용하여 수신측에서 송신측을 제어할 수 있는 양방향 전송제어가능한 영상신호 전송처리장치에 관한 것이다. 이를 위하여 송신단은 복합영상신호로부터 동기신호를 분리하기 위한 제1동기신호 분리수단과 제1동기신호 분리수단에서 출력하는 수평동기신호의 주기를 계수하여 소정의 수직블랭킹영역 동안 하이레벨신호를 출력하는 제1카운터와 제1카운터의 출력이 로우레벨신호일때는 휘도/색조수단에서 출력하는 복합영상신호를 절환하고 제1카운터의 출력이 하이레벨신호일때는 수신단의 제어신호를 상호 절환하는 제1절환수단 제1절환수단에서 절환된 제어신호를 입력으로 받아 송신단의 각 부를 제어하는 제1제어수단을 구비하고, 수신단은 사용자 제어명령을 입력하기 위한 키입력부와 복합영상신호로부터 동기신호를 분리하기 위한 제2동기신호 분리수단과 제2동기신호 분리수단에서 출력하는 수평동기신호의 주기를 계수하여 소정의 수직블랭킹영역동안 하이레벨신호를 출력하는 제2카운터와 제2카운터의 출력이 로우레벨신호일때는 휘도/색조수단에서 출력하는 복합영상신호를 절환하여 디스플레이 장치와 접속하고, 제2카운터의 출력이 하이레벨신호일때는 송신단을 제어하기 제어신호를 절환하여 상기 송신단과 접속하는 제2절환수단과 수신단의 전반부를 제어하고, 키입력부로부터 입력된 사용자 제어명령을 인코딩하여 인코딩된 제어신호를 제1절환수단으로 출력하는 제2제어수단을 구비한다. 따라서 수신측에서도 송신측을 손쉽게 제어할 수 있을 뿐만 아니라 별도의 전송라인을 구비할 필요가 없으므로 비용을 절감할 수 있는 효과가 있다.The present invention relates to a video signal transmission processing apparatus capable of bidirectional transmission control in a video system, and more particularly, to a video signal transmission processing apparatus capable of controlling a transmission side at a reception side using a predetermined region of a composite video signal. It is about. To this end, the transmitting end counts the period of the horizontal synchronization signal outputted from the first synchronization signal separation means and the first synchronization signal separation means for separating the synchronization signal from the composite video signal, and outputs a high level signal during a predetermined vertical blanking area. First switching means for switching the composite video signal outputted from the luminance / tone means when the output of the first counter and the first counter is a low level signal, and mutually switching the control signal of the receiver when the output of the first counter is a high level signal; A first control means for receiving the control signal switched by the first switching means as an input and controlling each part of the transmitting end, wherein the receiving end has a key input for inputting a user control command and a second for separating the synchronization signal from the composite video signal; A predetermined vertical blanking area by counting the period of the horizontal synchronizing signal outputted from the synchronizing signal separating means and the second synchronizing signal separating means When the second counter outputting the high level signal and the output of the second counter are low level signals, the composite video signal outputted by the luminance / color means is connected to the display device. When the output of the second counter is the high level signal, Controlling the transmitting end by switching a control signal to control the second switching means connected to the transmitting end and the first half of the receiving end, encoding a user control command input from the key input unit, and outputting the encoded control signal to the first switching means; Two control means are provided. Therefore, the receiving side can easily control the transmitting side, and there is no need to provide a separate transmission line, thereby reducing the cost.
