Abstract:
1. A method of video encoding comprising the steps of: dividing a picture into a set of regular shaped coding blocks having a predetermined alignment in relation to the area of the picture, each coding block corresponding to at least one group of elementary coding elements; determining at least one shape within a picture; selecting at least one subset of the coding blocks defining at least one area covering the at least one determined shape; determining as at least one separate coding object the selected at least one subset of the coding blocks; determining as a background object the subset of the coding blocks that corresponds to the part of the picture that excludes the at least one separate coding object; encoding the at least one separate coding object; and encoding as one coding object the background object, wherein the encoding the background coding object comprises the sub-step of defining coding slices in a scan-order so that the slices are composed by consecutive coding blocks skipping those basic coding objects which are included in the at least one separate coding object.
