Abstract
본 발명은 525/60 방식에서의 디지탈 브이.씨.알의 오디오 데이타 트랙 넘버 추출 방법에 관한 것으로, (a) 입력되는오디오 샘플 데이타중 몇번째 인가를 나타내는 12비트이 데이타를 카운트하는 단계와, (b) 12비트의 데이타를 div3처리하는 단계와, (c) 12비트의 데이타를 모드3 처리한 후 2를 곱하는 단계와, (d) (b) 및 (c)단계에서의 출력값을 더하는 단계와, (e) 모드5 처리하여 5를 더한후 그 값을 출력하는 단계를 포함하고 구성되어, 12 비트의 데이타를 비트별로 분해하여 가중치를 곱하고 이를 비트 별로 더하거나 비교하여 최종 백터값, 즉, 트랙넘버를 추출하기 때문에 값이 비싸고 크기가 큰 수치 연산의 일반적인 하드 웨어를 사용하지 않고도 트랙 넘버를 추출할 수 있는 장점이 있다.The present invention relates to a digital data track number extraction method of digital V.C.R in the 525/60 system, comprising: (a) counting data of 12 bits indicating the number of input audio sample data; b) div3 processing 12-bit data, (c) multiplying mode 12 by 12-bit data, and (d) adding output values in steps (b) and (c); and (e) mode 5 processing, adding 5 and outputting the result, and decomposing the data of 12 bits bit by bit, multiplying the weights, and adding or comparing the bits bit by bit to obtain a final vector value, that is, track number. Extracting tracks has the advantage of extracting track numbers without using expensive hardware and expensive hardware.
