摘要

When considering the multimedia production chain from the content creation to the end-user consumption, watermarking provides a well defined functionality: property right identification and copy-maker tracking. However, its place within this chain is not yet clearly stated. The present paper describes an objective study aiming at establishing the functional peculiarities in the cases when watermarking follows compression. First, some general limits concerning the transparency, robustness and capacity in compressed (MPEG-4 AVC) domain watermarking are identified. Then, these results are discussed and compared to the uncompressed domain watermarking case. The experiments were carried out on a video corpus of 5 video sequences, each of them of .3.5000 frames (about 25 minutes each), coded at 256kbit/s.
