Video and audio synchronous recording function of thermal imaging intelligent camera module
The quality of digital audio and the ability of synchronization with digital video should meet the use requirements: when playing back,
compared with the original scene sound, there should be no obvious lag or advance compared with the video image.
The basic requirement is that if a TV picture is recorded / played back, the mouth shape and voice of the characters should be basically the same.
There are many ways to synchronize video and audio signals, but the out of step time of video and audio signals should be less than 1 s.
