A method of encoding and decoding a scalable video data stream comprising a base layer and at least one enhancement layer. A scalable data stream is encoded, wherein the data stream includes at least one non-required picture in a temporal location of a layer wherein decoding of pictures in an upper layer at and succeeding the said temporal location in decoding order does not require said non-required picture, and wherein information of the at least one non-required picture is signalled in the scalable video data stream. In the decoding phase, the signalled information is decoded and pictures in a layer above the non-required picture at and succeeding the said temporal location in decoding order are decoded without decoding said non-required picture. |
