Abstract

본 발명의 디지탈 링크 시스템의 우선순위 선택장치는 하나의 VCR과 2대의 TV수상기를 연결하여 상호간에 동작을 제어할 수 있도록 하는 디지탈 링크 시스템에서 2대의 TV수상기에서 선택적으로 VCR의 동작을 제어하도록 하는 것으로 종래의 디지탈 링크 시스템은 VCR로 제1 및 제2TV수상기의 동작을 제어함은 물론 제1 및 제2TV수상기로 VCR의 동작을 제어하여 매우 편리하게 사용할 수 있는 반면에 제1 및 제2TV수상기가 서로 상이하게 VCR을 동작시켜 혼선을 발생 즉, 예를 들면 제1TV수상기의 사용자가 VCR을 정속재생 모드로 동작하게 제어하고, 제2TV수상기의 사용자가 VCR을 빠른 재생모드로 동작하게 제어하게 되면, VCR의 동작에 혼선을 가져오게 되고, 이로 인하여 사용자의 혼동을 일으키게 됨은 물론 VCR의 고장으로 판단하였다.Priority selection device of the digital link system of the present invention is to connect the one VCR and two TV receivers to control the operation of each other in the digital link system to control the operation of the VCR selectively in the two TV receivers The conventional digital link system can control the operation of the first and second TV receivers with a VCR, as well as control the operation of the VCR with the first and second TV receivers, while the first and second TV receivers are very convenient. When the VCRs are operated differently from each other to generate crosstalk, for example, when the user of the first TV receiver controls the VCR to operate in the constant speed playback mode, and the user of the second TV receiver controls the VCR to operate in the fast playback mode, This results in confusion in the operation of the VCR, which causes confusion of the user and of course, it is determined that the VCR is broken.

본 발명은 TV수상기가 VCR의 동작을 제어하는데 우선 순위를 부여하여 어느하나의 TV수상기만 VCR을 제어 할 수 있도록 함으로써 VCR의 동작에 혼선이 발생되지 않게 된다.In the present invention, the TV receiver gives priority to controlling the operation of the VCR so that only one TV receiver can control the VCR so that no interference occurs in the operation of the VCR.
