Analyze Algorithm of Low Bit-rate Video Watermarking Based on H.264
Zhang Chun-feng · Computer Knowledge and Technology · 2009
H.264 standard has the highest compressive efficiency in the current image standards, which bit stream's structure appears strong adaptability to the network. It is important that researching watermarking on H.264 standard to protect copyright of video in the network transmission. This paper briefly introduces the difference between H.264 and the other coding, and analyzes difficulty of embedding water-marking in this coding. Then different algorithms of video watermarking based on H.264 are compared. At last low bit-rate video water-marking in the future is prediction.
