1. A method of encoding comprising:
receiving, by a processor, a coding unit;
partitioning, by the processor, the coding unit into a set of hierarchical levels of prediction units including a first prediction unit of a first level of the set of hierarchical levels and a set of prediction units of a second level of the set of hierarchical levels, wherein the first prediction unit is larger than the set of prediction units; and
determining, by the processor, an intra-prediction mode for the first prediction unit based on a first sub-set of intra-prediction modes associated with the set of prediction units of the second level of the set of hierarchical levels,
the first sub-set of intra-prediction modes being a number of intra-prediction modes that is less than the number of intra-prediction modes in a corresponding set of intra-prediction modes.
