To each Intra 16x16 prediction macroblock, an Intral6x16PredMode is assigned, which specifies the Intra 16x16 prediction mode, and values of CodedBlockPatternLuma and CodedBlockPatternChroma are assigned as specified in Table 7-11. Intra 4x4 specifies the macroblock prediction mode and specifies that the Intra_4x4 prediction process is invoked as specified in clause 8.3.1. Intra_4x4 is an Intra macroblock prediction mode. Intra 8x8 specifies the macroblock prediction mode and specifies that the Intra_8x8 prediction process is invoked as specified in clause 8.3.2. Intra_8x8 is an Intra macroblock prediction mode. Intra_16x16 specifies the macroblock prediction mode and specifies that the Intra 16x16 prediction process is invoked as specified in clause 8.3.3. Intra_16x16 is an Intra macroblock
