METHOD OF CHECKING NEIGHBORING MACRO BLOCKS VALIDITY IN DMB VIDEO DECODER

摘要

The present invention relates to that, in particular, how to effectively check whether the macroblock currently being decoded and the surrounding macroblock within the same slice of the DMB video decoder. According to the invention, the address of the first macro block of each macroblock macroblock number (HMBNumber) and the slice of the horizontal direction without the need to have both having the slice number to determine if the neighboring block is included in the same slice which by using the (IniMBAddr), reduce unnecessary waste of memory, there is an effect of reducing the deterioration speed and power consumption due to the external memory access by the cache miss is not an external memory required.
