资源说明：In this work, a new real-time watermarkingtechnique on latest H.264/AVC video standard was proposed. The algorithm works in the compressed domain by embedding watermark bits into quantized DCT coefficients of 4×4 blocks of the I-frame during the Context-based Adaptive VariableLength Coding (CAVLC) process.CAVLC offers a lower computational complexity which is efficient to the algorithm.During watermark extraction, do not need to decode the entire video, which meets the requirement of the real-ti
