MOVING IMAGE CODING METHOD, MOVING IMAGE CODING APPARATUS, MOVING IMAGE CODING PROGRAM, AND MOVING IMAGE CODING DATA STRUCTURE

摘要

PROBLEM TO BE SOLVED: To more surely detect a slice synchronizing pattern even in the environment where a transmission error occurs in a moving image coding method by which the slice synchronizing pattern is changed by an F-code indicating a variable-length coding (VLC) method to be used for coding a motion vector, and a moving image signal is coded by performing the motion compensation using the motion vector. SOLUTION: In the moving image coding method, the F-code indicating the VLC method to be used for coding the motion vector is set for each slice in the method of coding the moving image signal by performing the motion compensation using the motion vector. The moving image coding method is provided with: an F-code determining step (1) for commonly determining the F-code for the unit of group-of-pictures; a motion vector coding step (2) for coding the motion vector by the VLC method indicated by the F-code; a synchronizing pattern creating step (3) for creating the slice synchronizing pattern according to the F-code; and an image coding step (4) for coding the moving image signal by performing the motion compensation in the motion vector.
