Claim 0:
1. An apparatus for decoding a video sequence of pictures, the apparatus comprising:
a decoder configured to determine a current coding unit to be decoded among coding units which are divided from a current picture by block partitioning, and decode, from a bitstream, syntax elements of a coding unit level related to the current coding unit; and
a reconstructor configured to reconstruct the current coding unit using the syntax elements of the coding unit level,
wherein the decoder is configured to decode the syntax elements of the coding unit level by performing a process comprising:
decoding prediction syntax elements for the current coding unit at the coding unit level, wherein the prediction syntax elements include a skip flag indicating whether the current coding unit has been predicted in a skip mode; and
after the decoding of the prediction syntax elements, decoding transform syntax elements for the current coding unit at the coding unit level, wherein the transform syntax elements include a single flag of coding unit cbf indicating whether all coefficients in both of a luma block and two chroma blocks constituting the current coding unit are zero,
wherein the transform syntax elements are not decoded until the decoding of the prediction syntax elements is completed, and are not decoded when the skip flag indicates that the current coding unit has been predicted in the skip mode.
