Abstract

An MPEG-encoded video signal includes groups of pictures (GOPs), each GOP having an intraframe coded (I) picture and a series of predictively encoded (P) pictures and bi-directionally predictively (B) pictures. Usually, the GOP structure IBBPBBP . . . is used. However, in order to embed a watermark in the MPEG-encoded video signal, the MPEG encoder is forced to produce a GOP structure which does not normally occur, e.g., a GOP including a BPP sequence. Different symbol values can be assigned to different positions of the BPP sequence in the GOP.
