摘要： A video decoding method involving intra prediction. The method includes: parsing a most probable mode (MPM) flag of a block while parsing symbols of the block of an encoded video from a received bitstream; determining whether a plurality of candidate intra prediction modes, the number of which is fixed, are used to predict an intra prediction mode of the block based on the MPM flag; if it is determined that the plurality of candidate intra prediction modes are used based on the MPM flag, determining the plurality of candidate intra prediction modes, the number of which is fixed, based on intra prediction modes of a left block and an upper block that are adjacent to the block while restoring the intra prediction mode of the block by using the parsed symbols after finishing the parsing of the symbols of the block.

摘要： Disclosed are a video encoding method and apparatus and a video decoding method and apparatus. The method of encoding video includes: producing a first predicted coding unit of a current coding unit, which is to be encoded; determining whether the current coding unit comprises a portion located outside a boundary of a current picture; and producing a second predicted coding unit is produced by changing a value of pixels of the first predicted coding unit by using the pixels of the first predicted coding unit and neighboring pixels of the pixels when the current coding unit does not include a portion located outside a boundary of the current picture. Accordingly, a residual block that is the difference between the current encoding unit and the second predicted encoding unit, can be encoded, thereby improving video prediction efficiency.
