Abstract
Aiming at new feature of the H.264/AVC video coding standard, a fragile watermark algorithm based on H.264/AVC low bit-rate video stream is proposed. In video coding side that after the end of the P frame motion vector search and the best motion vector prediction, the algorithm extracts the residual motion vector, and embeds the watermark in the residual of the motion vector. In the video decoder side the algorithm extracts and detects the watermark, the watermark detection algorithm does not require the participation of the original video. Experimental results show that this algorithm has a smaller bit rate change and the video distortion, can ensure effectiveness and practicality of the algorithm.关键词
