%X This paper proposed the adaptive activity quantization index modulation(AAQIM)watermarking algorithm for copyright protection in the network video transmission based on H.264. In AAQIM, embedded the watermark in block activity adaptively, thus dispersed the variation over host values of a region.The watermark embedded in I frame only slightly affected the successive P/B frames. Simulation results show that AAQIM guarantees a better performance in transparence. And the proposed method is extremely robust against re-encoding, noise attacks and filter.And it extracts watermark without the original video signal. Additionally, the proposed method is also simple and appropriate for real-time applications.
