Abstract

H.264/AVC is becoming a popular video codec for its better compression ratio, lower distortion and applicability to portable electronic devices. Thus, issues of copyright protection and authentication that are appropriate for this standard become very important. In this paper, a blind video watermarking algorithm for H.264/AVC is proposed. The watermark information is embedded directly into H.264/AVC video at the encoder by modifying the quantized DC coefficients in luminance residual blocks slightly. The watermark embedded in the residuals can avoid decompressing the video and to decrease the complexity of the watermarking algorithm. To reduce visual quality degradation caused by DC coefficients modifying, block selection mechanism is introduced to control the modification strength. Experimental results reveal that the proposed scheme can achieve enough robustness while preserving the perceptual quality.
