InterDigital filed 3 cloud gaming patents that pull motion information directly from game engines to streamline video compression. Rather than hunting for motion pixel by pixel, these methods tap into the game's internal depth buffers and camera transformation parameters to calculate where each block of pixels has moved. One approach builds a planar depth model for every coding block, using the engine's own depth data to compute geometrically accurate motion vectors that reflect true camera movement. Another tags blocks with camera motion metadata to skip expensive motion estimation when the camera, not the objects, is moving, cutting encoder latency for real-time game Streaming.

A single VR and AR patent tackles the challenge of updating 3D scenes in a running game engine without recompiling or rebuilding. The system introduces a translation layer that converts standardized scene description patches, expressed as JSON operations on glTF or MPEG scene graphs, into commands the game engine can execute at runtime. This decouples content authoring from engine-specific formats, letting developers modify immersive XR environments on the fly using format-agnostic scene data that the engine itself does not need to parse natively.
