AUDIO-VIDEO FLOW MARKED TO SYNCHRONIZE DIFFERENT COMPONENTS, METHOD AND INSTALLATION FOR ANALYSIS OF ARTIFACTS AND SYNCHRONISM OF SUCH A FLOW

摘要

The present invention relates to a marked audio-video stream comprising: a video stream composed of a succession of video frames, and an audio stream composed of a succession of audio frames, and a text stream composed of a succession of video frames. subtitle frames said marked audio-video stream being characterized in that: - each video frame comprises means for identifying the video synchronism, and - each audio frame comprises means for identifying the audio synchronism, and - each frame text contains a means of identifying the synchronism of the subtitles.
