Description: A novel semi—fragile blind watermark algorithm based on H．264 low bit—rate video stream was pro—
posed in this paper，copyright protection and content authentication Can be achieved jointly by embedding the robust waterraark
an d fragile watermark spectively during the process of interior prediction an d motion vector prediction which are
characteristic for H．264 standard．Through introducing the quan tization factor of H．264 in the embedding and prediction
mod e choice，the proposed scheme Can strengthen the watermarking resistance to video recoding and strike a good rate—
distortion balan ce for the waterm ark of lower bit—rate video st／ ea／n．which relieve bit—rates lossness from the waterm arking
embedding．Experimental results also demonstrate that this scheme iS very computational efi cient during watermark—
ing embedding an d extraction．
