摘要:
A system and method are described below for encoding interactive low-latency video using interframe coding. For example, one embodiment of a computer-implemented method for performing video compression comprises: detecting a maximum data rate of a communication channel between a server and a client; transmitting a video stream comprising a series of sequential frames from the server to the client; detecting that the maximum data rate will be exceeded if a particular frame of the sequence of frames is transmitted from the server to the client over the communication channel; and in lieu of transmitting the frame which could cause the maximum data rate to be exceeded, causing the client to re-render the previous frame of the sequence of frames, thereby effectively reducing the frame rate of the video stream rendered on the client.

A system and method are described for storing program code and data within an application hosting center. For example, one embodiment of a computer-implemented method comprises: subdividing program code and/or data used to execute an online application into a first type and a second type; storing program code and data of the first type in a first type of memory, the first type of memory providing relatively low latency memory access; storing program code and data of the second type in a second type of memory, the second type of memory providing relatively higher latency memory access compared to the first type of memory; retrieving program code and data from the first memory and the second memory in response to a client request to execute an online application; and transmitting a streaming interactive video stream representing images generated by the application to the client.
摘要:
A method comprising broadcasting a live game tournament in the form of a multicasted streaming interactive video stream from a hosting service to a plurality of viewers over the Internet. Audio from an announcer is overlaid by the hosting service onto the multicasted video stream.

A system and method are described below for encoding interactive low-latency video using interframe coding. For example, one embodiment of a computer-implemented method for performing video compression comprises: logically subdividing each of a sequence of images into a plurality of tiles, each of the tiles having a defined position within each of the sequence of images, the defined position remaining the same between successive images; encoding one of the tiles at a first defined position in a first image of the sequence of images using a first compression format and encoding the reminder of the tiles in the first image using the second compression format; and encoding one of the tiles at a second defined position in a second image of the sequence of images using the first compression format and encoding the reminder of the tiles in the first image using the second compression format; wherein the second compression format is dependent on previously-encoded tiles encoded according to the first compression format and/or the second compression format.

A system and method are described below for reducing the effects of packet loss in a video communication system. For example, one embodiment of a computer-implemented method comprises: logically subdividing each of a sequence of images of a video stream into a plurality of tiles, each of the tiles having a defined position within each of the sequence of images; and packing the tiles into a plurality of data packets to maximize the number of tiles which are aligned with boundaries of each of the data packets; and transmitting the data packets containing the tiles over a communication channel from a server to a client.
摘要:
An apparatus comprising one or more servers of a hosting service server center and a RAID that stores geometry for objects of a complex scene. The RAID being coupled to the one or more application or game servers and being operable to interactively stream the geometry on-the-fly during real-time animation associated with running of a game or application on the one or more servers. The geometry is being streamed with substantially no detectable latency.
摘要:
A method comprising combining Internet linear video together with interactive video content into a single video stream that is compressed and transmitted in the form of streaming interactive video through the Internet to a user client device.
摘要:
A method comprising running a web browser on one or more servers of a service center, and hosting files for a web page on a storage unit associated with the one or more servers. Upon receiving user input from a client device to the web browser at the service center, streaming interactive video web page is transmitted to the client device with substantially no detectable latency.

A computer-implemented system and method are described for online gaming. For example, a system according to one embodiment comprises: a video game server receiving user inputs related to an online video game and responsively executing program code of the video game to render a sequence of video images; a first stream encoder to compress the sequence of video images and generate a live video stream during a live gaming session with a user of a client device, the first stream encoder receiving channel feedback signals from the client device and responsively adapting compression of the sequence of video images based on the channel feedback signals, the first stream encoder continually transmitting the live video stream to the client device during the live gaming session with the user; a second stream encoder to compress the sequence of video images at a specified video quality and/or compression ratio unrelated to the channel feedback signal during the live gaming session with the user, thereby generating a High Quality (HQ) video stream, the HQ video stream having a relatively higher video quality and/or lower compression ratio than the live video stream; and a storage device for storing the HQ video stream for subsequent playback to the user of the client device and to other users upon request.
摘要:
A method by which a streaming interactive video user session is handed off from one streaming interactive video server to another without noticeable disruption to the video stream or the user interactivity.
