New Digital Video Watermarking Algorithm Against H.264 Compression
Zhaobin Liu · Science Technology and Engineering · 2009
H.264 standard for network transmission with a better support,research of watermarking on this standard has important effects on copyright protection in the network video transmission.Consequently,a new video watermarking arithmetic is put forwird which embeds watermarking by adjusting DC coefficients in large blocks of I frame which chose from the video streaming.The arithmetic doesn't need original video image when detecting watermarking so that it is a blind detection.Experiments indicate that arithmetic has a strong robustness to many attack schemes,such as multiple compression,noise attacks,frame delete,format conversion.There is some theoretical and practicality on copyright protection in the network video transmission.
