摘要

It gets more and more important for video copyright protection, it is necessary to provide eﬃcient H.264 compression domain watermarking for video Digital rights management(DRM). A new watermarking method based on H.264 compressed domain is proposed for video DRM, in which the embedding and extracting procedure are performed using the syntactic elements of the com-pressed bit stream. In this way, complete decoding is un-necessary in both embedding and extracting processes. Based on the analysis of the time and space, some appro-priate sub-blocks are selected for embedding watermarks, increasing watermark robustness while reducing the dec-lination of the visual quality. In order to avoid bit-rate increasing and strengthen the security of the proposed video watermarking scheme, only a set of nonzero coeﬃ-cients quantized in different parts of macroblocks is chosen for inserting watermark. The experiment results show the proposed scheme can achieve excellent robustness against some common attacks, the proposed scheme is secure and eﬃcient for video content DRM protection.
