Claim:
1. A method of decoding at least one coding unit from a bitstream of video data, the method comprising: decoding arithmetically coded data, coded consecutively in the bitstream, including a plurality of flags each for a different one of a plurality of prediction units in the coding unit to be decoded by using intra prediction, the flag indicating whether one of specific intra-prediction modes is to be used; decoding, bypass coded data, coded consecutively in the bitstream, including a plurality of pieces of data each for a different one of the plurality of prediction units; determining intra-prediction modes each for a different one of the plurality of prediction units each according to a different one of the flags each in the arithmetically coded data and a different one of the plurality of pieces of data in the bypass coded data; and decoding the coding unit using the determined intra-prediction modes.
