Abstract
본 발명은 디지탈 오디오신호의 복호화장치에 관한 것이다. 본 발명의 복호화장치는 입력되는 비트스트림중에서 불필요한 부분은 삭제하고, 필요한 부분만을 순차적으로 또는 군집으로 만들어 복호화기에서 요구하는 비트율과 동작주파수로 변환하여 출력하는 사전 분석기, 및 사전 분석기에서 변환된 신호를 청취 가능한 오디오신호로 복호화하는 디지털 오디오 복호화기로 구성된다. 따라서, 본 발명은 복호화기의 동작을 원활하게 해주며, 디지탈 오디오 복호화기가 MPEG 1칩으로 구성된 경우 MPEG 2의 비트스트림을 처리시 MPEG 1칩을 변형함없이 처리할 수 있는 효과를 제공한다.The present invention relates to an apparatus for decoding a digital audio signal. The decoding apparatus of the present invention deletes unnecessary portions of the input bitstream, sequentially or groups only necessary portions, and converts them into bit rates and operating frequencies required by the decoder, and outputs the converted signals from the pre-analyzer. And a digital audio decoder for decoding the audio signal into an audible audio signal. Accordingly, the present invention facilitates the operation of the decoder, and when the digital audio decoder is composed of MPEG 1 chips, it provides an effect of processing the MPEG 1 bit without modifying the MPEG 1 chip.
