A Watermarking-Based Multimedia Synchronized Transmission Scheme

Because the changes in network bandwidth and delay jitter,and other factors easily lead audio and video to the phenomenon of unsynchronization,and thus influence the media display.As to this,a watermarking-based audio and video synchronization transmission scheme is proposed in this paper.In this scheme,the audio data is embedded to video Q-DCT coefficient for tranamission.In the receiver,by extracting audio data from the video and reconstructing audio signal,the audio and video signals are compressed and transmitted with synchronization.Experiments show that the scheme not only has little influence on the image quality,but also achieves a very good synchronous player of audio and video.
