Abstract

본 발명은 디지탈 VCR의 기록과정에서 영상 및 음성데이타, 에러정정부호등의 기록해야 할 데이타를 실제 테이프기록포맷에 맞는 형태로 재배열 하여 헤드에 의해 기록된 때까지의 시스템동작을 제어하는 채널제어장치에 관한 것으로, 특히 채널제어과정을 채널제어부로 일원화하여 신호처리계의 동작을 안정시키고, 채널제어부의 내부구성을 롬을 사용하여 다순화한 디지탈 VCR의 기록채널제어장치에 관한 것이다. 본 장치는 채널제어부에서 헤드전환신호와 다른 기능동작을 제어하는 제어신호를 만들어서 신호처리를 일괄적으로 수행한다. 또한, 다른 기능들을 수해하는 여러개의 부블럭으로 이루어진 시스템구성 대신에 롬을 사용하여 처리과정을 간략화시켰다. 이와 같이 롬을 사용함으로써 기록패턴의 변화에 따른 대처가 가능하다.In the present invention, channel control for rearranging data to be recorded such as video and audio data, error correction code, etc. in the format of a digital VCR in a form suitable for the actual tape recording format and controlling the system operation until recording by the head is performed. The present invention relates to a recording channel control apparatus for a digital VCR in which a channel control process is unified with a channel control unit to stabilize the operation of a signal processing system, and the internal structure of the channel control unit is pluralized using ROM. The apparatus performs signal processing collectively by generating a control signal for controlling the head switch signal and other functional operations in the channel controller. In addition, the ROM is used to simplify the process instead of a system consisting of several subblocks that perform other functions. By using the ROM as described above, it is possible to cope with the change of the recording pattern.
