    Abstract: 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.

    Abstract: A method of cloud gaming is disclosed. The method including receiving an encoded video frame at a client, wherein a server executes an application to generate a rendered video frame which is then encoded at an encoder at the server as the encoded video frame, wherein the encoded video frame includes one or more encoded slices that are compressed. The method including decoding the one or more encoded slices at a decoder of the client to generate one or more decoded slices. The method including rendering the one or more decoded slices for display at the client. The method including begin displaying the one or more decoded slices that are rendered before fully receiving the one or more encoded slices at the client.

    Abstract: 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.
