Abstract

In some embodiments, a method determines a first set of reference pixels for a current block to be coded. The current block is split into a plurality of sub-partitions. The method processes a first sub-partition in the plurality of sub-partitions using the first set of reference pixels and a second sub-partition in the plurality of sub-partitions using the first set of reference pixels in parallel. Then the method processes a third sub-partition in the plurality of sub-partitions based on a second set of reference pixels determined from the processing of the first sub-partition and processing a fourth sub-partition in the plurality of sub-partitions based on a third set of reference pixels determined from the processing of the second sub-partition.
