Abstract:
A moving image decoding apparatus comprising:decoding means for decoding coded data consisting of a plurality of data contained in a plurality of macroblocks and multiplexed before and after a unique word; detecting means for detecting position information indicating an initial position of the coded data said decoding means decodes, and for detecting a number of the macroblocks constituting the coded data; reviewing means for estimating an initial position of next coded data from the position information and the number of the macroblocks detected by said detecting means, and for checking an occurrence of a discontinuity between the coded data and the next coded data on an image space; and resynchronization means for setting, if said decoding means completes decoding of the coded data without detecting any error in the coded data and if said reviewing means detects the occurrence of the discontinuity, a resynchronization point at an initial position of coded data subsequent to the next coded data.
