Abstract :
We present a scheme for jointly watermarking and compressing digital video. The amount of watermark added is adapted to the expected degradation of the watermark due to compression. This results in a more robust watermark. This is achieved without any appreciable decrease in the quality of the decoded video compared to the case when the watermark is not adaptive. Results are presented for the flower garden sequence.
