Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
미니 디스크(Mini Disc) 디코딩 시스템에서 SRMC(Shock Resistant Memory Controller)와 ATRAC(Adapted TransformAcoustic Coding) 디코더간 데이타 인터페이스 방법에 관한 것이다.The present invention relates to a data interface method between a Shock Resistant Memory Controller (SRMC) and an Adapted Transform Acoustic Coding (ATRAC) decoder in a mini disc decoding system.
2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention
버퍼 메모리를 통해 이미 버퍼링된 데이타를 다시 ATRAC 디코더에서 버퍼링 한 다음에 처리하게 됨에 따라 버퍼가 낭비될뿐만 아니라 디코딩에 소요되는 처리 시간이 증가되는 것을 개선한다.By buffering the data already buffered through the buffer memory and then processing it in the ATRAC decoder, the buffer is not only wasted but the processing time for decoding is increased.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
버퍼 메모리에 저장된 사운드 그룹의 데이타를 SRMC에 의해 ATRAC로 전송시 오디오 데이타에 대한 디코딩 정보들과 그의 복사정보들을 바이트단위로 교호적으로 전송한다.When the data of the sound group stored in the buffer memory is transmitted to the ATRAC by the SRMC, decoding information of the audio data and its copy information are alternately transmitted in byte units.
4. 발명의 중요한 용도4. Important uses of the invention
미니 디스크 디코딩 시스템에서 디코딩시 이용한다.Used for decoding in the mini disc decoding system.
