Title:
A SYSTEM AND METHOD FOR RENDERING DIFFERENTIAL VIDEO ON GRAPHICAL DISPLAYS
Document Type and Number:
WIPO Patent Application WO/2023/286925
Kind Code:
A1
Abstract:
A differential video rendering system, including 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.
