Audio/Video Synchronization Issues
Unlike analog NTSC Broadcast video, where audio and video are synchronized and processed as a single entity, digital media processing necessitates the separation of audio and video. Without the possibility of retrieving accurate timing information from a video signal, it is possible that an offset between audio and video signals may develop. This offset may stay constant or drift with time. Jay Yogeshwar of Front Porch Digital addresses timing issues associated with each of these processing steps to ensure proper synchronization.
