摘要：
An innovative practical video watermarking scheme based on MPEG-2 is proposed in this paper. By operating the compressed video data-stream directly, we embed watermarking information in DC coefficients of block image which is in the IDR picture, in DPCM process of MPEG-2 coder. Watermark can be extracted blindly without original images and complete decoding is unnecessary. The algorithm designs one kind of synchronization code in order to resolve the synchronization problem. Watermark information is embedded periodically for random testing. The experimental results show the proposed scheme can achieve good excellent robustness to common video processing methods such as low bit rate MPEG-2 compression and synchronization attacks.
