Abstract

In all hybrid video coders the raster scanning order of macroblock has been used. Such order scheme make parallel processing of macroblock very difficult. or even impossible The paper presents alternative method of macroblock ordering called “diamond scan”. This scheme of macroblock ordering allows for strong parallelization of macroblock processing and to have benefit from multicore processors (GP and GPU). Applying presented scheme leads to create a more efficient software and hardware implementations, in terms of energy consumption and efficient use of available equipment.
