A Novel Watermarking Method For Wyner-Ziv Video Coding

With the development of the theory of distributed source coding, more and more schemes on distributed video coding were proposed. However, there isnpsilat any watermarking method for it. In this paper, we propose firstly a watermarking method for the distributed video coding. In the proposed method, the watermarking info was embedded into the key frames for the sake of reducing the affection to the quality of the video. Meanwhile, the characteristic of the distributed video decoding is taken into consideration ensuring that the watermarking info was preserving in the reconstructed Wyner-Ziv frame. The experiment results have proved that the proposed watermarking method may solve the watermarking problem of distributed video coding system without affecting the quality of the video.
