Video-audio synchronization |
摘要 |
<p>To maintain lip-sync when a video signal has been edited or switched at a video frame boundary, the associated audio signal is advanced or retarded to the closest audio frame boundary. Any error introduced by this constraint is accumulated and carried forward to direct a subsequent advance or retard decision. In this way, the cumulative error can be kept within an acceptable tolerance.</p> |
