Abstract:

In order to solve the problem of synchronization of audio and video efficiently, an embedding scheme, which applies the size variability of matching blocks, for synchronization compression of audio and video is presented during the inter prediction process. At the transmitter terminal, the matching blocks with different sizes carry corresponding audio information according to coding standards. So the audio will be embedded into video stream by choosing the matching blocks. Then synchronous coding is applied to the mixing video/audio. At the receiver terminal, the audio signal is extracted from the video signal, and then the audio and video signals are reconstructed, respectively. Experiment results show that, within affordable cost and little quality drop of the video signal, the proposed synchronization coding scheme performs well.

Key words: communication, synchronous coding, inter prediction coding, audio and video
