....retrieval without knowledge of the original video sequence is advantageous, because storing and synchronizing two versions of a video sequence (one unwatermarked and one watermarked) results in a lot of practical problems. Previous work on watermarking includes watermarking of still images [KZ95, ODB96, NP96, Car93, ACC95, BGM96], audio [BTH96] and multimedia data in general [CKLS95] However, there is no previous work except [HG96, HG97] that deals specifically with watermarking of video, be it uncompressed or compressed. We present a scheme for watermarking of MPEG 2 compressed video which is of considerably lower ....

.... sequence must not occupy more bit rate than the unwatermarked) and interoperability between uncompressed and compressed domains (the watermark is embedded into compressed video and must be retrievable from decompressed copies) Previous work on watermarking includes watermarking of still images [1, 2, 3, 4, 5], audio [6] and multimedia data in general [7] We present a new scheme for watermarking of MPEG 2 compressed video which is of considerably lower complexity than schemes for watermarking of uncompressed video which require decompression and re compression when a compressed video sequence has to ....

....been used by secret services and agents for centuries, only that this art was called steganography . For formatted digital text documents, the idea was revived in 1994 by Brassil et al. 1] Even before, Caronni had worked on first methods for embedding invisible information into digital images [2,3]. Subsequent publications deal with embedding watermarks (in some publications also called label or signature ) into audio [4] uncompressed digital images [5 10] JPEG compressed digital images [5] uncompressed digital video [11] compressed digital video [11 13] and 3D polygonal models ....
