Abstract

This paper proposes a new block based DCT selection and a robust video watermarking algorithm to hide copyright information in the compressed domain of the emerging video coding standard H.264/AVC. The watermark is first quantized and securely inserted. To achieve invisibility and robustness, the high entropy DCT 4x4 blocks within the macroblocks are selected to minimise the distortion caused by the embedded watermark and then scrambled using Linear Congruential Generator (LCG) technique. This approach leads to a good robustness by maintaining good visual quality of the watermarked sequences. The experimental results demonstrate the effectiveness of the algorithm against some attacks such as re-compression by the H.264 codec, transcoding and scaling.
