Fast watermarking of MPEG-1/2 streams using compressed-domain perceptual embedding and a generalized correlator detector [PDF]

open access: yes, 2004
A novel technique is proposed for watermarking of MPEG-1 and MPEG-2 compressed video streams. The proposed scheme is applied directly in the domain of MPEG-1 system streams and MPEG-2 program streams (multiplexed streams).
