摘要： Provided is a video decoding method including determining a data unit for intra prediction from a video picture; obtaining, from a bitstream, intra prediction type information indicating whether to predict the data unit according to a first intra prediction type that predicts using predetermined prediction information or a second intra prediction type that predicts using data units adjacent to the data unit; determining a first data unit predicted according to the first intra prediction type and a second data unit predicted according to the second intra prediction type, based on the intra prediction type information obtained from the bitstream; generating a first prediction value with respect to the first data unit predicted according to the first intra prediction type by using the predetermined prediction information; and generating a second prediction value with respect to the second data unit predicted according to the second intra prediction type by using the data units adjacent to the data unit.
