ab: Summary: 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.
