摘　　要：针对当前视频信息隐藏算法比较复杂、计算量大等问题,结合H.264编码标准特有的帧内预测新技术,提出一种基于H.264/AVC的视频信息隐藏算法。基于隐秘信息与最优模式的映射规则,最优模式在与其相邻的方向间调整方向,即将1比特的隐秘信息嵌入到预测模式中。提取时仅对帧内预测模式进行解码即能得到隐秘信息。实验结果表明,该算法在保持良好视频质量的同时,具有较高的隐藏容量。A view of the complexity and the large amount of computation of the current video information hiding algorithm, a new video information hiding algorithm based on H. 264/AVC is proposed in combina tion with the intra prediction technology of H. 264 coding standard. Based on the mapping rule of the hid den information and the optimal mode, the 1 bit secret information can be embedded into the prediction modes by adjusting the direction between the optimal mode and its adjacent directions. The secret informa tion can be obtained only by decoding the intra prediction mode during extraction. The experimental re suits show that the algorithm has a high hidden capacity while maintaining good video quality.
