Abstract

A method for constructing a most probable mode (MPM) list for prediction process corresponding to video block is provided. The method includes determining whether a left block of a current coding block is available, in response to determining that the left block of the current coding block is available, adding an intra prediction mode of the left block into an MPM list; determining whether an above block of the current coding block is available, in response to determining that the above block of the current coding block is available, adding an intra prediction mode of the above block into the MPM list; adding an offset to the prediction mode of the left block to obtain a new prediction mode; and adding the above-offset prediction mode into the MPM list when the above-offset prediction mode is not in the MPM list. The MPM list is used to improve coding efficiency.
