ABSTRACT:
Representative picture extracting means apparatus extracts representative pictures from a coded input signal 101 which consists of representative pictures, motion parameters for motion compensation which refers the representative picture, and reference relationships, and outputs a coded representative picture signal 103. The signal is decoded by a representative picture decoding means apparatus, and output as a decoded representative picture signal 105 to a delay memory 106. On the other hand, representative picture reference relationship extracting means apparatus extracts reference relationship additional information 113, and outputs it to decoded signal output controlling means apparatus. The sequence of outputting the representative pictures is determined on the basis of the reference relationship additional information 113, and an output control signal 115 is output to the delay memory 106. The delay memory 106 outputs the decoded representative picture signal 105 as a decoded output signal 107, on the basis of the output control signal 115.
