Abstract:
The method for decoding an intra-picture prediction mode includes the steps of: determining whether the intra-picture prediction mode of a current prediction unit is identical to a first intra-picture prediction mode candidate or a second intra-picture prediction mode candidate based on bit information; and when the intra-picture prediction mode of the current prediction unit is identical to the first intra-picture prediction mode candidate and/or to the second intra-picture prediction mode candidate, determining whether the first intra-picture prediction mode candidate or the second intra-picture prediction mode candidate is identical to the intra-picture prediction mode of the current prediction unit on the basis of additional bit information, and decoding the intra-picture prediction mode of the current prediction unit.

Claim (Index 2):
A method of encoding a video signal, comprising:\n determining an intra-prediction mode of a current block; generating, a prediction sample relating to the current block included in the video signal to be encoded by performing intra prediction; deriving a first candidate intra-prediction mode and a second candidate intra-prediction mode of a current block; and encoding n-bit information specifying whether the intra-prediction mode of the current block is identical to the first candidate intra-prediction mode or the second candidate intra-prediction mode; when the intra-prediction mode of the current block is identical to one of the first candidate intra-prediction mode and the second candidate intra-prediction mode, encoding m-bit information specifying one of the first candidate intra-prediction mode and the second candidate intra-prediction mode identical to the intra-prediction mode of the current block; wherein deriving the first candidate intra-prediction mode and the second candidate intra-prediction mode comprises: deriving a first neighbor prediction mode based on a first neighbor block adjacent to the current block, wherein when the first neighbor block is available, the first neighbor prediction mode is set to as an intra-prediction mode of the first neighbor block, and wherein when the first neighbor block is unavailable, the first neighbor prediction mode is set to a DC mode; deriving a second neighbor prediction mode based on a second neighbor block adjacent to the current block, wherein when the second neighbor block is available, the second neighbor prediction mode is set to as an intra-prediction mode of the second neighbor block, and wherein when the second neighbor block is unavailable, the second neighbor prediction mode is set to a DC mode; and deriving the first candidate intra-prediction mode and the second candidate intra-prediction mode from the first neighbor prediction mode and the second neighbor prediction mode, wherein when the first neighbor prediction mode and the second neighbor prediction mode are different, the first candidate intra-prediction mode and the second candidate intra-prediction mode are determined without comparing values of the first neighbor prediction mode and the second neighbor prediction mode.
