Abstract

본 발명은 방송용 비데오카메라(Video Camera)와 비데오카세트레코더(Video Cassette Recorder; 이하, “VCR”이라 함) 사이에 연결되는 어댑터장치에 관한 것으로, 특히 방송용비데오카메라의 디지탈 직렬데이타에 VCR제어신호를 부가하여 별도의 제어를 위한 케이블없이도 직접적인 VCR제어가 가능한 어댑터장치에 관한 것이다. 종래에는 방송용 비데오카메라에서 VCR로의 직접적인 제어가 불가능했기 때문에 제어신호용 케이블을 따로 설치하여 사용함으로써 번거로움이 따랐다. 그러나, 본 발명은 TRS 또는 ID 및 데이타신호가 실리는 직렬데이타 신호에 제어신호도 함께 실어 VCR의 제어를 할 수 있으므로 하나의 케이블로 디지탈 영상신호 및 제어신호가 동시에 전송될 수 있는 효과를 제공한다.The present invention relates to an adapter device that is connected between a broadcast video camera (Video Camera) and a video cassette recorder (Video Cassette Recorder, hereinafter referred to as "VCR"), in particular the VCR control signal to the digital serial data of the broadcast video camera In addition, the present invention relates to an adapter device capable of direct VCR control without a cable for separate control. In the related art, since direct control from a broadcast video camera to a VCR was not possible, it was troublesome to separately install and use a control signal cable. However, the present invention can control the VCR by including a control signal on a serial data signal carrying a TRS or ID and data signal, thereby providing an effect that a digital video signal and a control signal can be simultaneously transmitted through a single cable. .
