Abstract:
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 group into a plurality of reference sub blocks, and pixels in the prediction pixel group into a plurality of prediction sub blocks, each reference sub block having pixels from more than one of the plurality of prediction units; performing, by the intra prediction unit, encoding processing on the plurality of reference sub blocks; and subsequently performing, by the intra prediction unit, encoding processing on the plurality of prediction sub blocks, using results of the encoding processing on the plurality of reference sub blocks.
