Overview. 33 angular predictions for both luma and chroma and two non-directional. predictions (DC, Planar).. PB sizes from 4×4 up to 64×64.. Replication Benefits. Replication enhances tolerance to failure. Performance can be improved in different ways. Placing replicas in the proximity of the process using them. Replicating servers and subsequently dividing the work among them.
