摘要

A method increases the efficiency of a memory bank and greatly reduces the risk of erasure of frame data which are required for coding, decoding or display. FM1a, FM1b, FM2a and FM2b are the first frame area of the first image sequence, the second frame area of the first image sequence, the first frame area of the second image sequence and the second frame area of the second image sequence, respectively. AD12a and AD12b are the first address start location of the first image sequence and the second address start location of the first image sequence, respectively. The frame sizes SZ1a and SZ1b are reserved from the respective start locations toward higher addresses in the first image sequence, respectively. The frame sizes SZ2a and SZ2b are reserved from AD12b-SZ2a and AD34a-SZ2b toward higher addresses in the second image sequence, respectively.
