Advanced Micro Devices had four patents in gaming during Q2 2024. AMD’s patents focus on reducing latency in cloud gaming and remote video streaming systems. The first patent introduces an adjustable delay in the frame rendering pipeline to reduce VSYNC presentation latency, while the second patent involves dynamic determination of a target frame rate for synchronization between server and client devices, optimizing rendering and encoding frequencies for reduced latency and missed frames.

Application: Server-side frame render timing delay to reduce client-side frame present delay (Patent ID: US20240196033A1)
The patent filed by Advanced Micro Devices Inc. describes a method and system for reducing latency in cloud gaming or remote video streaming systems by introducing an adjustable delay in the frame start timing at the server based on feedback from the client device regarding observed vertical synchronization (VSYNC) presentation latencies. This delay allows for the rendering and encoding pipeline at the server to be shifted back, ensuring that video frames are available to be presented at the client device closer to their respective VSYNC signal assertions. The coordination between the client device and the server involves the client device reporting observed VSYNC presentation latencies to the server, which then determines the frame start delay to be introduced for upcoming frames, ultimately reducing overall frame latency.
The method involves rendering a sequence of video frames, encoding them, and transmitting them to the client device, with the server receiving feedback on VSYNC present latencies from the client device. The server then introduces a frame start delay based on this feedback, shifting back frame start triggers for subsequent frames. The client device, on the other hand, receives the encoded video frames, decodes them, observes VSYNC present latencies, and transmits feedback to the server. This feedback includes observed latencies and can help in determining if a decoded video frame will miss a corresponding VSYNC signal assertion, allowing for adjustments to be made to ensure smoother video presentation.
