Abstract
First pictures as reference for inter-picture prediction of an incoming moving-picture and second pictures are coded. The first pictures are coded by intra-picture or unidirectional inter-picture predictive coding. The second pictures are coded by bidirectional inter-picture predictive coding by referring the first or their locally-decoded pictures to obtain a moving-picture bitstream. The bitstream is multiplexed with obtained motion activity information. Incoming first bitstreams are multiplexed into a bitstream at a rate lower than a total bit rate of the incoming first bitstreams. Each bitstream has first bitstreams of the first and second pictures. A code amount of the multiplexed bitstream is obtained for each reproduction period as virtual buffer occupancy, according to which a decimation rate is set on the second pictures. The second pictures bitstreams are decimated from the incoming first bitstreams according to the decimation rate to obtain second bitstreams, which are multiplexed to obtain the multiplexed bitstream.
