Digital watermarking plays an important role for copyright protection, content authentication, and annotation of digital multimedia. To embed watermark quickly, we embed the watermark in the compressed domain instead of the frequency domain. For high imperceptibility, a new video watermarking based on Human Visual System (HVS) is proposed. It embeds the watermark in the block that is highly tolerant of noise. The proposed algorithm directly substitutes the Variable Length Code (VLC) without
