[0002] This application claims priority to US Provisional Application Serial No. 60 / 851,953, filed October 16, 2006, the entire disclosure of which is hereby incorporated by reference. technical field

[0003] The present invention relates to the field of moving pictures, in particular to the problem of storage of reference pictures used for coding the moving pictures. Background technique

[0004] Many inter-coding systems use reference pictures, and the use of such reference pictures helps reduce the size of the coded bitstream. The result of this type is that the coding efficiency is higher than that of using intra coding techniques alone. Many coding standards thus combine intra and inter coding techniques to code a bitstream from a series of moving pictures. As known in the prior art, different types of reference pictures are used for coding standards, such as "I" pictures (intra) that are coded only by using elements ...
