MOVING IMAGE DECODING TIMING ESTIMATE METHOD, MOVING IMAGE CODER AND MOVING IMAGE DECODER

摘要

PROBLEM TO BE SOLVED: To provide the moving image decoding timing estimate method, the moving image coder, and the moving image decoder in which a decoding timing of a coding frame to be decoded 2nd is estimated accurately with a small arithmetic operation amount in the case of decoding the coding frame of the moving image. SOLUTION: An MPEG video decoder 403 extracts a number denoting a display order of coded frames decoded at first from a video bit stream 407, identification data of frame structure/field structure, identification data of a display method of a pattern in the case of a frame structure, identification data of frame structure/field structure of a coded frame decoded 2nd, identification data of a display method of a pattern in the case of a frame structure and data denoting a display period of a pattern. A decoding start time of a 2nd coding frame is estimated based on data extracted by a decoding start timing control circuit 408 and continuity of pattern display and the decoder 403 decodes the coding frame.
