Cloud Gaming & Streaming

Huawei received 1 patent addressing the challenge of rendering responsiveness in cloud gaming environments. The application describes a system that divides the rendering workload, with the server handling background elements while the client device renders characters locally. To prevent visible stuttering or freezing when network delays occur, the server pre-renders extra background content beyond the player's current viewport, calculating the size of this buffer zone based on how fast objects can move and how long network packets take to arrive. This allows players to control characters immediately without waiting for server round trips, while the pre-rendered backgrounds mask any lag in receiving updated environmental data.

InterDigital CE Patent Holdings, SAS filed 1 patent focused on improving video compression for cloud gaming streams. Rather than treating rendered game frames as ordinary video that needs to be compressed like footage from a camera, the application embeds information about the game engine's virtual camera directly into the compressed video format. This metadata includes details like where the camera sits in 3D space, which direction it faces, and its field of view. By making the compression algorithm aware that the content comes from a deterministic 3D rendering process instead of unpredictable real-world scenes, the system can make smarter decisions about how to reduce file size while maintaining visual quality and minimizing streaming delays.
