Activision Blizzard holds 2 granted patents across Graphics (1) and Platforms (1).
The Graphics patent covers a system that uses LED wall displays to capture lighting data from skin and materials for realistic character rendering in video games. In the Platforms category, the company describes a hash-based content delivery network with chunked distribution and local caching designed to help geographically distributed development teams synchronize large game builds efficiently.
The Graphics patent describes a system that treats massive LED walls as high-resolution light source arrays for capturing how light interacts with skin and materials. Instead of requiring a separate light stage with multiple exposures, the approach maps each pixel on the LED wall to a corresponding pixel in the game engine, capturing reflectance data in real time across any lighting scenario. The LED wall simultaneously serves as both the background display and the lighting characterization source, consolidating what previously required separate workflows into a single unified system.
Activision's Platforms patent addresses the challenge of distributing enormous game builds across studios in different geographic locations without overwhelming network connections. The system breaks content into chunks using hash-based addressing, then stores those chunks in a two-tier hierarchy with local studio cache nodes feeding from centralized object storage. Only genuinely new data chunks transfer across the network rather than entire files, and a label-based reference system with expiration attributes handles cleanup across all nodes at once. The approach extends to development kits on consoles, which can stream content directly from local cache nodes during execution.
