Abstract

A new algorithms of video watermarking based on MPEG-2 and AVS is studied in this paper. In this method, three middle frequency coefficients are selected in each block when get the quantized DCT coefficients. Watermark is embedded in these coefficients by the characteristics of the concavity and convexity of equation. By this method, the watermarking is robust to Gauss noise and quantization attack, and also to salt and pepper noise. Then a new drift compensation method is introduced. It is less complex compared with the H&G arithmetic. Further more the quality of the picture of the P frame and B frame is improved after this compensation.
