Abstract (en)

[origin: WO2009080926A2] The invention relates to a method of coding a video sequence as a video stream (fi1) comprising a base layer (Ci0) and one or more refinement layers (Ci1, Ci2, Ci3, Ci4, Ci5) destined for users having different user profiles, characterized in that at least one of said refinement layers (Ci2, Ci3, Ci4, Ci5) codes a visual object distinct from the visual objects coded by said base layer or by another of said refinement layers, said visual object corresponding to a semantic content destined specifically for the users of one of said profiles.
