MOVING IMAGE DECODING APPARATUS AND MOVING IMAGE DECODING METHOD

摘要

A moving image decoding apparatus and moving image decoding method wherein the picture quality degradation is small even when an error occurs in decoding or the like in an encoding system that refers to a plurality of frames to perform a prediction encoding. An error correcting part (6) comprises an image selecting part (6₁) and an error concealing part (6₂). The image selecting part (6₁) selects a frame to be used as a concealment image and notifies the error concealing part (6₂) of, as information of the selected frame, the frame number (frame_num) of the selected image or the number of a frame memory in which the selected image is stored. The error concealing part (6₂) uses additional information and the selected frame information, which is notified of by the image selecting part (6₁), to conceal the macro block where the error has occurred.
