Abstract

본 발명은 멀티미디어 시스템에 관한 것으로, 특히 컴팩트 디스크 플레이어에서 비디오 비트 스트림을 제어하여 비디오 2배속 재생이 가능하도록 한 멀티미디어 시스템의 비디오 배속 재생 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to multimedia systems, and more particularly, to a video double speed playback method of a multimedia system that enables video double speed playback by controlling a video bit stream in a compact disc player.

이러한 본 발명은 2배속 재생시 압축된 비디오 비트 스트림 데이타를 디코딩하는 디코딩 동기신호와 수직동기신호와를 일치시키고 오디오를 뮤팅시키며, 비디오 비트 스트림으로 화면 형태를 판독하여 양방향 화면일 경우 스킵하고, 예측된 화면 또는 기준 화면일 경우 상기 비디오 비트 스트림을 디코딩하고, 디코딩 데이타의 에러 유무를 검색하여 에러가 존재할 경우 기디코딩 완료된 화면을 반복 디스플레이하고 에러가 없을 경우에는 현재 디코딩된 화면을 디스플레이함으로써 달성된다.The present invention matches the decoding synchronization signal and the vertical synchronization signal that decodes the compressed video bit stream data during double speed playback, mutes the audio, reads the screen form into the video bit stream, and skips when the screen is bidirectional. Decoded video bit stream in the case of a picture or reference screen, and searching for the presence or absence of error in the decoded data, repeatedly displaying the previously decoded screen if there is an error and displaying the currently decoded screen if there is no error.

Claims (1)

2배속 재생시 압축된 비디오 비트 스트림 데이타를 디코딩하는 디코딩 동기신호와 수직동기신호와를 일치시키고 오디오를 뮤팅시키는 제1과정과, 상기 비디오 비트 스트림으로 화면 형태를 판독하여 양방향 화면일 경우 스킵하고, 예측된 화면 또는 기준 화면일 경우 상기 비디오 비트 스트림을 디코딩하는 제2과정과, 디코딩 데이타의 에러 유무를 검색하여 에러가 존재할 경우 기디코딩 완료된 화면을 반복 디스플레이하고 에러가 없을 경우에는 현재 디코딩된 화면을 디스플레이하는 제3과정으로 이루어짐을 특징으로 하는 멀티미디어 시스템의 비디오 배속 재생 방법.A first step of matching the decoding synchronization signal and the vertical synchronization signal to decode the compressed video bit stream data during double speed reproduction and muting the audio; and reading the screen form with the video bit stream and skipping if the screen is bidirectional. A second process of decoding the video bit stream in the case of the predicted picture or the reference picture, and searching for the presence of the error of the decoding data and repeatedly displaying the previously decoded picture if there is an error, and displaying the current decoded picture if there is no error. And a third process of displaying the video. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
