Abstract

In this paper, we proposed a novel audio video synchronization compression approach based on H.264/AVC, which is audio is embedded into quantized DCT coefficients of video in the encoder utilizing the parity properties of coefficients, then audio and video signals are compressed simultaneously. Different from the traditional methods, the proposed approach realizes the synchronization between video and audio in the coding layer. We've verified the synchronization processing method based on H.264/AVC using JM Model and experimental results show that this method does not increase the amount of data, and audio signal can be extracted without distortion. At the same time the algorithm has little effect on the quality of video.
