Claim 5:
6. The differential video rendering system as claimed in claim 5, wherein the at least one processor is further configured to:
generate a blocklist including the plurality of tile size regions based on the list of the dirty tiles;
select a root block from the blocklist, wherein the root block is a superset of all blocks in the blocklist;
select, in a sequential order, a second number of tile size regions among the plurality of tile size regions in the blocklist;
add the selected second number of tile size regions to the root block in the sequential order until a number of child regions of the root block exceeds the predefined criteria corresponding to the pre-defined optimal number of regions; and
generate a first level of the hierarchal region tree based on the addition of the selected second number of tile size regions to the root block.
