The synchronization of audio and video has become one of key issues of Internet multimedia applications.In order to resolve the problem,an embedding scheme for synchronized compression of audio and video is presented.At transmitter,audio is embedded into DCT(Discrete Cosine Transform) coefficients of video images as hiding signal,and then compression and coding is applied to the video signal in which audio signal has been embedded.At receiver,the audio signal will be extracted from video signal,then reconstruct the audio and video signal,respectively.The experimental results show good performance for restored video and audio signal through hybrid compression scheme proposed.

为了更好地解决音频与视频同步问题,提出了一种嵌入式音视频混合信号同步压缩编码算法。在发送端将音频信号作为隐藏信息,嵌入视频图像的DCT(Discrete Cosine Transform)系数中,然后对嵌入了音频信号的视频信号进行压缩编码,在接收端从视频信号中提取出音频信息,再对音频和视频信号进行重构,得到恢复后的音频与视频。该方法在不增加音频和视频压缩数据量,同时保证音频和视频主观质量没有明显降低的情况下,实现了音视频信号同步压缩。
