MOVING PICTURE ENCODING METHOD AND DEVICE, MOVING PICTURE DECODING METHOD AND DEVICE, RECORDING METHOD, AND MOVING PICTURE DECODING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an image encoding method in which interruption of reproduction is blocked without increasing the processing load in decoding.

SOLUTION: The moving picture encoding method is a moving picture encoding method of encoding a moving picture by switching between a variable-length encoding scheme for performing adaptive encoding according to a circumferential state and a binary mathematical encoding scheme for performing adaptive encoding according to the circumferential state. A continuous section becoming an object of seamless reproduction is determined, and a moving picture is encoded in each reproduction section wherein a picture at the head in the order of decoding is an in-screen encoded picture by using one of the variable-length encoding scheme and mathematical encoding scheme to generate a moving picture stream. Then management information is generated which includes the first flag information indicating that the encoding system for the continuous reproduction section is fixed to one of the variable-length encoding scheme and mathematical encoding scheme for every reproduction section.
