PROBLEM TO BE SOLVED: To improve coding efficiency and facilitate accelerated operation of an encoder.SOLUTION: The encoder encodes a first set of control (including prediction) data and motion data and a second set of control (including prediction) data and texture data to produce a base layer bitstream, encodes a third set of control (including prediction) data and motion data and a fourth set of control (including prediction) data and texture data to produce an enhancement layer bitstream, and multiplexes the data into a single output bitstream. The third and fourth sets of control data include interlayer prediction control data. A second prediction estimator and a second comparator set interlayer prediction control data values in one or more groups of coded units of an input picture so that corresponding interlayer prediction control data values in coded units of the input picture associated with the one or more groups of coded units of the input picture are not transmitted. |
