Abstract
Recently, the H.264/AVC, which was standardized jointly by ISO/IEC and ITU-T, has been expanding its applications in various areas. This standard includes many advanced component techniques compared to the existing MPEG techniques. Intra prediction which is to predict the spatial data in an intra frame in one of them. But it has a serious defect that it needs large amount of calculation. To overcome this defect, this paper proposed a method to reduce about 60% of the amount of calculation with only O.02dB of image quality degradation. This method determines the calculation directly without much pre-calc cluation process by referring the left block(s) and upper blocks(s) that were processd already. Comparing to the exi sting methods, its image quality degradation is so small that it is expected to be used in many areas. Especially in the wireless appliances such as DMB phone which has restricted power source, we expect it would be used efficiently.
