摘要： An intra prediction mode decoding method includes reconstructing an intra prediction mode group indicator and a prediction mode index, constructing an MPM group including three intra prediction modes using valid intra prediction modes of left and top blocks of the current block, determining the intra prediction mode corresponding to the prediction mode index in the intra prediction group corresponding to the intra prediction mode group indicator, and assigning the lowest mode numbers to non-directional modes. Therefore, it is possible to reduce the amount of information for encoding the intra prediction mode of the current block by using intra prediction modes having higher possibility of being equal to the intra prediction mode of the current block. Also, it is possible to reduce the amount of information by assigning lowest mode numbers to the non-directional modes.

摘要： A reconstructed block creating method is provided which includes decoding an intra prediction mode using an intra prediction mode group indicator and a prediction mode index, constructing a prediction block, inversely quantizing a received residual signal using a quantization parameter and adaptively inversely transforming the residual signal using the intra prediction mode to create a residual block, and adding the prediction block and the residual block to create a reconstructed block. The quantization parameter is reconstructed using a minimum quantization CU size, and the minimum quantization CU size is determined by a parameter transmitted from a picture parameter set. Therefore, it is possible to improve image quality by adaptively adjusting a quantization parameter of a current block depending on the size of a coding unit and enhance compression efficiency of an image by effectively encoding/decoding the quantization parameter.

摘要： A method for encoding an intra prediction mode according to the present invention selects an intra prediction mode for a current block, determines the number of valid MPM candidates by checking the validity of MPM candidates of the current block, and if the number of valid MPM candidates is less than a previously set number, adds additional intra prediction modes as MPM candidates. MPM candidates can be adaptively added on the basis of the directionality of valid MPM candidates. Additionally, during the encoding of residual intra prediction modes, residual intra prediction modes are realigned on the basis of the directionality of valid MPM candidates. Accordingly, the present invention allows the information for encoding the intra prediction mode of the current block to be minimized by adding MPM candidates or realigning the residual intra prediction modes on the basis of the directionality of valid MPM candidates.
