1. A video decoding method comprising:
obtaining, from a bitstream, encoding order information indicating an encoding order indicating whether a second coding unit is decoded prior to a first coding unit in a current coding unit, the first coding unit and the second coding unit being split from the current coding unit;
obtaining encoding information indicating an intra prediction mode for the first coding unit among a plurality of intra prediction modes, the plurality of intra prediction modes including directional modes and non-directional modes; and,
when the encoding order information indicates that the second coding unit is decoded prior to the first coding unit and the encoding information indicates a first mode among the plurality of intra prediction modes, obtaining a predicted sample in the first coding unit using a left sample, a bottom-left sample, a right sample, a bottom-right sample and a upper sample,
wherein the right sample and the bottom-right sample are located in the second coding unit adjacent to the first coding unit,
the left sample, the bottom-left sample and the upper sample are located in coding units adjacent to the first coding unit, the coding units being decoded prior to the first coding unit.
