<p><P>PROBLEM TO BE SOLVED: To design the memory area of a receiving device compatible with a coding method that does not limit the capacity of the memory area. <P>SOLUTION: There is provided a level analyzer 100a that determines the maximum number of codable on-screen pixels (Nfpx) on the basis of a level identifier (Lst) indicating a user-specified coding level and the maximum number of stored pixels (Nspx) that can be stored in the picture memory of a decoding device. On the basis of the maximum number of on-screen pixels (Nfpx) and an input image size (number of vertical pixels (h) and number of horizontal pixels (w)), it is judged whether an input image can be coded or not and, at the same time, the number of reference candidate pictures (the maximum number of reference pictures) that can be referenced during inter-picture predictive coding is calculated. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
