Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and
extraction of the watermarks are done in the compressed domain.
The mean of the low-frequency DCT coefficients of the video is
temporally modulated according to the information bits. To
reduce complexity, we embed watermark in the prediction error
signals of the B-fr a mes. Experimental results show that the
proposed scheme achieves high video quality and robustness to
camcorder recording, trans-coding, fr a me-rate conversion, and
geometric attacks on common test videos.
