Method and system for measuring audio and video synchronization error of audio/video encoder system and analyzing tool thereof

摘要

A method for measuring audio and video synchronization error of an audio/video encoder system is provided. The method includes steps of: producing a reference video data having a first time length and including a particular image pattern and a reference audio data having a second time length; inputting the reference video data and the reference audio data into the audio/video encoder system to produce an encoded video data and an encoded audio data; processing the encoded video data and the encoded audio data respectively to produce a detected video data having the first time length and including the particular image pattern and a detected audio data having the second time length; and detecting a first time point of an audio data of the reference audio data synchronized with the particular image pattern of the reference video data and a second time point of an audio data of the detected audio data synchronized with the particular image pattern of the detected video data by an analyzing tool, and calculating a difference between the first time point and the second time point.
