This month's Streaming & Broadcasting category includes 1 filed patent application from Sony.
The patent covers video encoding technology that adjusts the use of B-frames based on the type of content being streamed, specifically distinguishing between cutscenes and interactive gameplay. Sony describes a system that increases B-frame usage during cutscenes, where lower latency demands allow for greater compression, while keeping encoding responsive during active gameplay sessions.
Sony received 1 patent focused on how video encoding can be made context-aware during game streaming. The application describes a system that monitors the game's own state to determine when a noninteractive sequence, such as a cutscene, is underway, and uses that moment as a trigger to increase the number of B-frames within a group of frames. Because cutscenes do not require real-time player input, the higher latency that comes with more B-frames is acceptable, and the tradeoff allows for reduced bandwidth consumption. During active gameplay, where responsiveness matters, the encoding profile shifts back to minimize delay rather than prioritize compression.
