A system includes a video source device connected to a video destination device via a network. The video source device includes a network interface and an encoder coupled to the network interface. The encoder is configured to encode a first stream of rendered video frames having a first frame rate to generate a second stream of encoded video frames for transmission over the network via the network interface, wherein the second stream has a second frame rate greater than the first frame rate. As part of this encoding process, the encoder is configured to selectively encode multiple instances of at least one video frame of the first stream for inclusion in the second stream to compensate for the difference between the first frame rate and the second frame rate.

Selective multiple-instance encoding of video frames to provide target frame rate during network transmission

An electronic game server receives a request from a client device to establish a real-time interactive gaming session, determines a device capability of an output device associated with the client device, determines a connection capability of the network connection, determines one or more target quality parameters for the real-time interactive gaming session based on the device capability and the connection capability, selects a first virtual machine of the plurality of virtual machines based on the one or more target quality parameters, establishes the real-time interactive gaming session with the client device, and provides to the real-time interactive gaming session, in accordance with the resource profile of the first virtual machine, resources for processing inputs from the client device and generating gameplay outputs in accordance with the processed inputs within the real-time interactive gaming session.

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 method performed at an electronic device includes: executing an application; establishing a session between the executing application, a remote server associated with the application, and a media device that transmits output from the session to an output device, wherein the output from the session includes output from the executing application; and presenting to users of one or more second electronic devices on which the application is not executing and/or installed a session identifier associated with the session, wherein the session identifier facilitates joining of the session by the second electronic devices and identifies a controller configuration implementable on each of the one or more second electronic devices for enabling the users of the one or more second electronic devices to interact with the session.

Network impairment simulation framework for verification of real time interactive media streaming systems

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.

A computer-implemented system and method are described for managing audio chat for an online video game or application. For example, a system according to one embodiment comprises: an online video game or application execution engine to execute an online video game or application in response to input from one or more users of the video game or application and to responsively generate audio and video of the video game or application; and a chat subsystem to establish audio chat sessions with the one or more users and one or more spectators to the video game or application, the chat subsystem establishing a plurality of audio chat channels including a spectator channel over which the spectators participate in audio chat and a user channel over which the users participate in audio chat.

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.
