MOVING PICTURE ENCODING METHOD AND MOVING PICTURE DECODING METHOD

摘要

A moving picture encoding device (1) includes a map creation section (113) for creating an information map for variable speed reproduction which is information required for variable speed reproduction for the picture type Ptype, a variable length encoding section (112) for encoding and arranging the information map for variable speed reproduction on an encoding stream Str, a detection section (114) for detecting necessity of encoding of the picture parameter set PPS referenced by a picture to be encoded, and a common information addition section (115) for adding the picture parameter set PPS whose encoding has been detected to be necessary by the detection section (114) to the picture to be encoded.
