Benefits of technology
This patent is about systems that stream content like gaming over the internet. One way to make the experience smoother is to synchronize the signals between the server and the device that's playing the game. This can make sure that the signals are in the correct order and can align with each other's phases, but may have a different frequency. The patent is about how to make this synchronization to reduce delays in the game play.
Problems solved by technology
Unfortunately, the demand is also pushing up against limits of the capabilities of network connections and the processing performed at the server and the client that is responsive enough to render high quality images as delivered to the client.

Embodiment Construction
[0043]Although the following detailed description contains many specific details for the purposes of illustration, anyone of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the present disclosure. Accordingly, the aspects of the present disclosure described below are set forth without any loss of generality to, and without imposing limitations upon, the claims that follow this description.
[0044]Generally speaking, the various embodiments of the present disclosure describe methods and systems configured to reduce latency and / or latency instability between source and target devices when streaming media content (e.g., streaming audio and video from video games). In particular, in some embodiments of the present disclosure, VSYNC signals between a cloud gaming server and a client are synchronized and offset. Due to differences in clocks at the cloud gaming server and the client, VSYNC signals of the cloud ga...

A method is disclosed including setting, at a server, a server VSYNC signal to a server VSYNC frequency. The server VSYNC signal corresponding to generation of video frames during frame periods for the server VSYNC frequency. The method including setting, at a client, a client VSYNC signal to a client VSYNC frequency. The method including sending compressed video frames from the server to the client over a network using the server VSYNC signal, wherein the compressed video frames are based on the generated video frames. The method including decoding and displaying, at the client, the compressed video frames. The method including analyzing the timing of one or more client operations to adjust the relative timing between the server VSYNC signal and the client VSYNC signal, as the client receives the compressed video frames.
