Abstract
A process to detect video glitches and audio-video synchronization errors arising during playback or capture. The process encodes an external time stamp into video and audio streams directly at the output of a digital media playback device. The process captures the stamped video and audio streams and analyzes the external stamp by comparing it with a presentation time stamp and a capture time stamp.
