InterDigital CE Patent Holdings, SAS filed 2 patents across Cloud Gaming (1) and VR & AR (1).
The Cloud Gaming patent covers a codec that leverages game engine camera data and depth planes to predict motion vectors, reducing compression latency for streamed 3D games. The VR & AR patent describes a system for translating standardized XR scene description patch data (glTF/JSON) into live game engine updates, allowing dynamic 3D scene modification at runtime without requiring engine-specific rebuilds.
InterDigital filed 1 cloud gaming patent that rethinks video compression for streamed 3D content by tapping directly into the game engine's internal state. Instead of analyzing pixels to guess how objects moved between frames, the codec reads depth information and camera transformation data that the engine already maintains, then uses those values to calculate motion vectors. This approach bypasses the computationally expensive pixel-domain motion search that traditional video encoders perform, treating the game engine's 3D scene representation as a compression resource rather than encoding the rendered output in isolation.
The 1 VR and AR patent tackles the challenge of updating immersive 3D scenes on the fly without forcing developers to rebuild content for each game engine. It introduces a translation layer that interprets standardized scene description patches, expressed as JSON Patch operations on glTF or MPEG scene graphs, and converts them into the specific entity updates that a given game engine expects. This lets content creators author XR experiences using open standards while the runtime system handles the conversion to engine-native commands, separating the authoring pipeline from the implementation details of Unity, Unreal, or other rendering Platformss.
