Moving image decoding apparatus and moving image coding apparatus

摘要

A data storage unit (103) stores an image frame in which an image frame which consists of coded data having a data loss or error received by a receiving unit (100) and complementary coded data which is received by receiving unit at a later time are rearranged into normal sequence. A redecoding unit (105) decodes the image frame stored in the data storage unit (103) with reference to one or more already-decoded image frames required for the decoding, and stores the decoded image frame in a frame additionally-storage unit (104). A decoding unit (101) decodes an image frame with reference to an image frame stored in either a frame storage unit (102) or the frame additionally-storage unit 104 according to a command from a control unit (106).
