摘要 提出了一种在H.264帧间预测过程中嵌入音频的音视频同步压缩编码方法,利用H.264中匹配块的尺寸可变性,解决了音视频同步编码问题。在发送端,根据编码准则,不同尺寸的匹配块携带不同的音频信息,通过对匹配块的选择将音频压缩流嵌入视频中,然后对嵌入音频的视频流进行压缩编码。在解码端,根据嵌入准则,提取音频信息,再对音频和视频信号进行重构和恢复。实验表明,本文方法在一定开销内,视频质量下降较小的情况下,实现了音视频同步压缩编码和传输。 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.
