Abstract
A method is provided of coding a video sequence as a video stream having a base layer and one or more refinement layers destined for users having different user profiles. A visual object is coded in at least one of the refinement layers codes, which is distinct from visual objects coded in the base layer or in another of the refinement layers. The visual object corresponds to semantic content destined specifically for the users of one of the profiles.
