摘    要:利用H.264/AVC标准中DCT系数的奇偶特性.在编码端将音频比特流嵌入到视频DCT系数中一起压缩传输,在解码端解出视频同时根据相应算法提取出音频信息,从而实现音视频的同步压缩.实验表明该方法在不增加数据量的前提下,可以无失真地还原出音频信号,对视频质量影响很小.

关 键 词:音频编码  视频编码  同步  离散余弦变换

Abstract:The audio bit-streams are embedded into the DCT coefficient of video images to be encoded and transmitted together at the time of encoding using the characteristics of parity of the DCT coefficients, then get the video images through the process of decoding at the receiver and at the same time in accordance with the appropriate algorithm to extract audio information.The method achieves the synchronization of audio and video compression.Experimentation shows that this method can extract the audio information...
