Abstract

Disclosed is a parallel intra prediction method for video data, including: dividing, by an intra prediction unit, pixels included in at least one prediction unit configuring a coding unit or a sub-coding unit so as to belong to any one of a reference pixel group and a prediction group; generating, by the intra prediction unit, reference sub blocks and prediction sub blocks, respectively, using reference pixels belonging to the reference pixel group and prediction pixels belonging to the prediction pixel group; performing, by the intra prediction unit, encoding processing on the reference sub blocks; and performing, by the intra prediction unit, encoding processing on the prediction sub blocks.

First claim

What is claimed is:

1. A parallel intra prediction method for encoding video data in a coding unit (CU) or a sub-coding unit (Sub-CU), comprising:
dividing, by an intra prediction unit, the CU or the Sub-CU into a plurality of prediction units;
classifying, by an intra prediction unit, each pixel in each of the plurality of prediction units into one of a reference pixel group and a prediction pixel group;
dividing, by the intra prediction unit, pixels in the reference pixel gr…
