Method of automatically testing audio-video synchronization |
摘要 |
A method of testing audio/video synchronization comprising calculating a frequency of a device used to encode a digital stream based on program clock references calculating first time differences between audio decoding time stamps and actual audio decoding times; calculating second time differences between audio presentation time stamps and actual audio presentation times; calculating third time differences between video decoding time stamps and 4 actual video decoding times; and calculating fourth time differences between video presentation time stamps and actual video presentation times.
