Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
디지탈 비디오 디스크 재생장치의 시스탬 디코데에서 메모리의 전송 데이타 인터페이스에 관한 것이다.A transmission data interface of a memory in a system decoder of a digital video disc player.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
광디스크 재생장치에서 동기모드 및 비동기모드를 설정하여, 설정된 모드에 의거하여 전송하기 위한 메모리의 전송데이타 인터페이스 장치 및 방법을 제공함에 있다.An apparatus and method for transmitting data interface of a memory for setting a synchronous mode and an asynchronous mode in an optical disc reproducing apparatus and transmitting them based on the set mode are provided.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
디지탈 비디오 디스크를 기록매체로 하는 재생장치의 시스템 디코더에서, 마이컴의 제어하에 메모리에 저장된 데이타 전송요구신호를 출력하는 오디오/비디오 디코더로 상기 데이타를 전송하기 위한 인터페이스 방법은 상기 오디오/비디오 디코더로 일정한 주기의 데이타 스트로브 신호를 출력하는 과정과, 동기모드로 설정될 시상기 데이타 전송요구 신호에 의해 데이타 전송허가 신호를 출력하고, 상기 데이타 전송 허가 신호가 활성화일시 상기 데이타 스트로브 신호에 동기되어 상기 전송데이타를 출력하는 과정과, 비동기모드 설정될 시 상기 데이타 전송요구신호가 발생될 때마다 상기 스트로브 신호에 동기되어 상기 전송데이타를 출력하는 과정으로 이룬다.In a system decoder of a reproducing apparatus using a digital video disc as a recording medium, an interface method for transmitting the data to an audio / video decoder that outputs a data transfer request signal stored in a memory under the control of a microcomputer is fixed to the audio / video decoder. Outputting a data transmission permission signal in response to a process of outputting a data strobe signal of a period and the data transmission request signal set in the synchronous mode, and synchronizing with the data strobe signal when the data transmission permission signal is activated And a step of outputting the transmission data in synchronization with the strobe signal whenever the data transmission request signal is generated when the asynchronous mode is set.
4. 발명의 중요한 용도4. Important uses of the invention
DVD재생장치의 시스템 디코더에서 메모리로부터 데이타를 읽어서 오디오/비디오 디코더로 전송하기 위해 이를 구현한다.This is implemented by the system decoder of the DVD player to read data from the memory and transfer it to the audio / video decoder.
