Video decoding system

Save the present invention is to rearrange, in particular, the macro-block to the case of using the DDR SDRAM minimize memory access number of the macro blocks in the DDR SDRAM, minimize read unnecessary additional word by DDR characteristic out of the memory related to a video decoding system; Thereby, it is possible to efficiently perform a memory access of a macroblock for a frame, decoding and display of the video decoder. In particular by reducing the overall number of video decoding time required to reduce the margin in the memory used to provide other add-ons to the digital broadcast receiver. Macro-block relocation, DDR SDRAM, shared
