Patent ID: 11936883
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A differential video rendering system, comprising:
a graphics processing unit (GPU);
a graphical display coupled to the GPU;
a video decoder configured to decode a bitstream of encoded data into a plurality of sets of decoded blocks;
at least one processor configured to:
generate, based on a first set of the plurality of sets of decoded blocks, a first differential video frame comprising a plurality of sets of differential regions,
normalize each set of the plurality of sets of differential regions to a fixed size block to provide a normalized plurality of sets of differential regions,
map a respective set of the normalized plurality of sets of differential regions to align with a respective tile size region of a plurality of tile size regions conforming with the GPU,
generate a hierarchal region tree based on the normalized plurality of sets of differential regions mapped to the plurality of tile size regions, and
generate a plurality of optimal regions based on the hierarchal region tree satisfying a predefined criteria corresponding to a pre-defined optimal number of regions and a predefined efficiency parameter; and

a graphics rendering engine configured to render the first differential video frame on the graphical display based on the plurality of optimal regions and a group of differential regions.
