Abstract

본 발명은 동영상데이터에 대한 오디오데이터를 부분적으로 돌비처리한 디지털비디오디스크의 재생시에 부분적인 돌비처리영역을 인식하여 돌비AC-3에 의한 오디오처리를 수행하기 위한 DVD재생시스템의 돌비오디오 부분처리방법을 제공한다.The present invention relates to a Dolby audio partial processing method of a DVD playback system for performing audio processing by Dolby AC-3 by recognizing a partial Dolby processing area when playing a digital video disc which is partially Dolby processed audio data for moving image data. To provide.

그에 따라 본 발명은 제1-제N패킷의 MPEG-2알고리즘에 의해 동영상/오디오정보가 수록된 디지털비디 디스크(D)로부터 독취된 동영상/오디오정보데이터를 MPEG-2알고리즘에 의해 디코딩하는 MPEG-2오디오/비디오디코더(18)와, 돌비처리된 오디오정보데이터를 돌비신호처리하는 돌비AC-3회로부(20)를 갖춘 디지털 비디오재생시스템에 있어서; 상기 디지털비디오디스크(D)의 재생시에 상기 제1-제N패킷에 각각 매핑되어 있는 각 패킷의 오디오데이터스트림에 대한 스트림타입(Stream Type)의 지정데이터를 인식함에 의해, 스테레오 형태의 지정데이터를 갖는 패킷의 스테레오처리된 오디오데이터스트림이 상기 MPEG-2오디오/비디오디코더(18)를 통해 디코딩되도록 하고, 돌비AC-3 형태의 지정데이터를 갖는 패킷의 돌비AC-3처리된 오디오데이터스트림이 상기 돌비AC-3회로부(20)를 통해 돌비신호처리되도록 하는 단계로 이루어진 것을 특징으로 한다.Accordingly, the present invention provides the MPEG-2 algorithm which decodes the moving picture / audio information data read from the digital video disk (D) containing the moving picture / audio information by the MPEG-2 algorithm of the first-Nth packet by the MPEG-2 algorithm. A digital video playback system having an audio / video decoder 18 and a Dolby AC-3 circuit section 20 for processing Dolby signals of Dolby-processed audio information data; When the digital video disc D is reproduced, stereo type designated data is recognized by recognizing stream type designation data for the audio data stream of each packet mapped to the first to Nth packets. The stereo processed audio data stream of the packet having the packet is decoded by the MPEG-2 audio / video decoder 18, and the Dolby AC-3 processed audio data stream of the packet having the specified data in the form of Dolby AC-3 is Characterized in that the step Dolby signal processing through the Dolby AC-3 circuit unit 20.
