Method and apparatus for intra-prediction video coding/decoding

Abstract

An intra-prediction coding and decoding method is provided, in which a picture to be encoded is received in coding units, each of the coding units is divided into a plurality of sub-units, an IPM is determined for each coding unit, residual data is acquired for each sub-unit of each coding unit according to the determined IPM, and information about the IPM of each coding unit and the residual data of each sub-unit of each coding unit are encoded.
