Abstract
본 발명은 MPEG방식에 의해 비디오 신호를 부호화해서 에스버스를 통해 외부로 전송할 수 있는 워크스테이션의 비디오 카드에 관한 것으로서, 종래에는 에스버스(16)는 인터럽트 제어기(14)의 스케줄링에 의해 동작 즉, 에스버스(16)가 마스터로 동작하고 JPEG부호화기(10)가 슬레이브로 동작하기 때문에 에스버스(16)를 통해 JPEG부호화기(10)의 출력을 전송하는 시간이 많이 걸리는 결점이 있었으나, 본 발명에서는 MPEG방식에 의해 비디오 신호를 부호화해서 에스버스(26)를 통해 외부로 전송할 경우, 에스버스(26)가 슬레이브로 동작하고 제어부(24)가 마스터로 동작함으로써 에스버스(26)를 원하는 만큼 점유할 수 있으므로 상기 결점을 개선시킬 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video card of a workstation capable of encoding a video signal by MPEG and transmitting it externally through an esbus. In the related art, the esbus 16 is operated by scheduling of the interrupt controller 14, that is, Since the SBus 16 operates as a master and the JPEG Encoder 10 operates as a slave, there is a drawback in that it takes a long time to transmit the output of the JPEG Encoder 10 through the SBus 16. When the video signal is encoded and transmitted to the outside through the bus 26, the bus 26 operates as a slave and the controller 24 operates as a master, thereby occupying the bus 26 as desired. Therefore, the above defect can be improved.
