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.

Synchronizing a frequency of a client VSYNC signal to a frequency of a server VSYNC signal

A method for encoding including executing game logic built on a game engine of a video game at a cloud gaming server to generate video frames. The method including executing scene change logic to predict a scene change in the video frames based on game state collected during execution of the game logic. The method including identifying a range of video frames that is predicted to include the scene change. The method including generating a scene change hint using the scene change logic, wherein the scene change hint identifies the range of video frames, wherein the range of video frames includes a first video frame. The method including delivering the first video frame to an encoder. The method including sending the scene change hint from the scene change logic to the encoder. The method including encoding the first video frame as an I-frame based on the scene change hint.

Encoding a video frame as a reference frame based on a scene change hint at a cloud gaming server

A method for cloud gaming. The method including receiving one or more encoded slices of a video frame at a client, wherein the video frame was generated at a server while executing a video game, and encoded by an encoder at the server into the one or more encoded slices. The method including decoding a first encoded slice at a decoder of the client before fully receiving the one or more encoded slices of the video frame.

Overlapping operations at a server and a client for a video frame to reduce latency in cloud gaming applications

A method is disclosed including setting, at a plurality of devices, a plurality of VSYNC signals to a plurality of VSYNC frequencies, wherein a corresponding device VSYNC signal of a corresponding device is set to a corresponding device VSYNC frequency. The method including sending a plurality of signals between the plurality of devices, which are analyzed and used to adjust the relative timing between corresponding device VSYNC signals of at least two devices.

Synchronizing display of video frames between client devices in a multi-tenant configuration

A method is disclosed including setting, at a server, a server VSYNC signal to a server VSYNC frequency defining a plurality of frame periods. The server VSYNC signal corresponding to generation of a plurality of video frames at the server during the plurality of frame periods. The method including setting, at a client, a client VSYNC signal to a client VSYNC frequency. The method including sending a plurality of compressed video frames based on the plurality of video frames from the server to the client over a network using the server VSYNC signal. The method including decoding and displaying, at the client, the plurality of compressed video frames. The method including analyzing the timing of one or more client operations to set the amount of frame buffering used by the client, as the client receives the plurality of compressed video frames.

Dynamic client buffering using server and client VSYNC signals of received video frames for cloud gaming

A method for cloud gaming. The method including generating a plurality of video frames when executing a video game at a cloud gaming server. The method including encoding the plurality of video frames at an encoder bit rate, wherein the plurality of video frames that is compressed is transmitted to a client from a streamer of the cloud gaming server. The method including measuring a maximum receive bandwidth of a client. The method including monitoring the encoding of the plurality of video frames at the streamer. The method including dynamically tuning a parameter of the encoder based on the monitoring of the encoding.

Buffer drain rate tuning to a measured maximum receive bandwidth measured for a client device when streaming

A method is provided, including: executing a first session of a video game by a cloud gaming system, wherein executing the first session generates a first game state of the video game for gameplay of the video game by a first user; streaming the gameplay of the video game over a network to enable the gameplay of the video game by the first user; receiving, during said gameplay, a command to share an interactive playable portion of the gameplay of the video game by the first user; responsive to the command, providing to a second user access to the interactive playable portion of the video game, through execution of a second session of the video game that generates a second game state of the video game for gameplay of the interactive playable portion by the second user.

Method for sharing a portion of gameplay of a video game

A method for cloud gaming. The method including generating a video frame when executing a video game at a server. The method including scanning-in the video frame to an encoder at the server scanline-by-scanline. The method including encoding one or more encoder slices as one or more encoded slices at the encoder, wherein each encoded slice is delivered to a buffer at an encoder fill rate. The method including draining a first encoded slice from the buffer to stream the first encoded slice at a buffer drain rate over a network to a client, wherein the first encoded slice is streamed over the network before fully encoding the one or more slices of the video frame.

Overlapping scan-in and encode at the server

Synchronization of a VSYNC signal of a first device to a VSYNC signal of a second device

Methods and systems for managing processing resources of an online game include executing the online game for one or more users. Each user is provided access to virtual locations in a gaming world of the online game. A compute is assigned for processing gaming interactivity of the one or more users in the gaming world. A number of users accessing a region within a virtual location are determined. When the number of users exceeds a predefined limit for the compute assigned to the users in the region, the region is divided into a plurality of sub-regions and additional compute is assigned for the region so that the compute and the additional compute can process gaming interactivity for the users in each of the sub-regions defined in the gaming world.
