A system and method are described for managing the state of an online video game. A method includes initiating a new online video game in response to user input from a client device, the online video game being in a first state on a first server when initiated; executing the online video game on the server, thereby causing the online video game to enter a second state; pausing or terminating the online video game; determining differences between the first state and the second state and generating difference data containing the differences; transmitting the difference data over a network to a second server; and recreating the second state from the difference data and the first state in response to user input indicating that the user wishes to resume the online video game and in response to the second server being selected as the server on which to execute the video game.

System and method for streaming game video

A computer-implemented system and method for streaming video from a server to a client are described. For example, a method according to one embodiment comprises: receiving at the server a request for video content from the client; in response to the request, determining the hardware/software configuration of the client; generating and/or selecting a temporary decoder based on the hardware/software configuration of the client; transmitting the temporary decoder to the client, the client installing the temporary decoder; encoding and streaming the requested video content from the server to the client, the video content being encoded based on the capabilities of the temporary decoder, the video content being decoded by the temporary decoder and rendered on the client; detecting that the client has ended the session with the server; and in response to detecting that the client has ended the session, temporarily disabling and/or removing the temporary decoder from the client.

Temporary decoder apparatus and method

A computer-implemented system and method are described for performing video compression by an online video game service is provided. One example method includes receiving user input by a server and the user input is received from a client device over a network established between the client device and the server. The user input is from an input device associated with the client device and the client device and the input device are used to access the server to play a video game. The method further includes executing the video game on the server while receiving user input from the input device, and the video game produces a video output including a sequence of video images of the video game. Encoding each of the sequence of video images in a video encoding resource of the server to generate a sequence of encoded video frames and transmitting the sequence of encoded video frames by the server over the communication channel to the client device for decoding to produce a corresponding sequence of decoded video frames. The sequence of decoded video frames is configured to be rendered on a display device associated with the client device. The method further includes detecting a change in a communication channel characteristic of the communication channel, and the detected change is based on feedback information received by the server. The feedback information is received from the client device and dynamically adjusting a compression ratio for said encoding of the sequence of encoded video frames based on the detected change in the communication channel characteristic.

System and method for compressing video frames or portions thereof based on feedback information from a client device

A computer-implemented system and method are provided for performing video compression including encoding a plurality of video frames or portions thereof according to a first encoding format; transmitting the plurality of encoded video frames or portions to a client device; receiving feedback information from the client device, the feedback information usable to detect whether one or more video frames or portions thereof have not been successfully received and/or decoded; determining, in response to detecting that one or more video frames or portions thereof have not been successfully received and/or decoded, whether to encode a new video frame or portion thereof according to a second encoding format or to encode the new video frame to be dependent on the last video frame or portion thereof known to have been successfully received and/or decoded.

System and method for utilizing forward error correction with video compression

Methods and systems for processing instructions by an online video game hosting system are provided. One example method includes receiving a control signal for a video game. The control signal is received by a server of the online video game hosting system, and the control signal is transmitted from a client device to the server over a network. Then, executing the online video game by the server while receiving the control signal. The executing causes generation of a sequence of video frames and encoding the sequence of video frames to generate a first compressed sequence of video frames and generate a second compressed sequence of video frames. Transmitting the first compressed sequence of video frames to the client device over the network for decoding by the client device to produce a first decoded sequence of video frames for displaying on a display of the client device. Receiving feedback information from the client device, the feedback information used to determine whether one or more of the first compressed sequence of video frames has been successfully decoded at the client device and modifying the encoding of the sequence of video frames in response to the feedback information. The second compressed sequence of video frames are directed to a storage associated with the server and wherein the quality of the second compressed sequence of video frames is higher than a quality of the first compressed sequence of video frames.

System and method for selecting a video encoding format based on feedback data

A system and method of playing a video game in a streaming mode includes executing a selected video game on an assigned game server, receiving execution control signals corresponding to user inputs to a client device to generate multiple video frames. Encoding the video frames in a shared hardware compression. Some of the encoded video frames depend on a preceding frame. A first and a second encoded video frame are transmitted to the client device. A first feedback signal from a decoder in the client device identifies that the second encoded video frame was not received the decoder. A third encoded video frame dependency is adjusted to produce an adjusted third encoded video frame that depends from the first encoded video frame and the adjusted third encoded video frame is transmitted to the client device.

System and method for compressing video based on latency measurements and other feedback

A computer-implemented system and method are described for performing video compression. For example, a method according to one embodiment comprises: encoding a plurality of video frames or portions thereof according to a first encoding format; transmitting the plurality of encoded video frames or portions to a client device; receiving feedback information from the client device, the feedback information usable to determine whether data contained in the video frames or portions has not been successfully received and/or decoded; in response to detecting that a video frame or portion thereof has not been successfully received and/or decoded, encoding a video frame or portion thereof according to a second encoding format; and transmitting the video frames or portions thereof to the client device.

System and method for accelerated machine switching

A system and method for performing video compression and streaming video from an online hosted video game or application. The online hosted video game or application is streamed to the client with a latency such that the user has the perception that the selected video game or application is responding instantly to the control signals received from the client device. In addition, feedback information received from the client device is used to determine characteristics of a communication channel between a server and the client. The video stream encoding is adjusted based on the detected communication channel characteristics, while maintaining a latency such that the user has the perception that the selected video game or application is responding instantly.
