摘要:
A system for conveying and reproducing images for use with interactive applications is described. The system includes one or more application modules producing images for a display, and a display server for deriving encoded representations of the images and forwarding them to one or more clients. The client includes one or more user input devices such as a touchpad or touchscreen, and forwards information derived from the data received from these devices to the display server. The information is also used locally to modify reconstructed images derived from the encoded image representations received from the display server. The modified reconstructed images are displayed on a video screen.

A server interactively serves client applications and client applications make estimates until updates are received from the server based on user input from the client. Processors on both the server and client execute applications with images. A video encoder in the server estimates images in response to the client user input and forwards a compressed data stream to the client. A video decoder of the client obtains images from memory and estimates images and reconstructs images from a compressed data stream in synchronization with an encoder of the server using the user input. A client display displays a region from memory of the one or more estimated images.

An agent manages multipath communications between a first network and a second network. The first network and a second network are wirelessly coupled by links through a plurality of wireless cellular devices. A link status monitor maintains a list of wireless cellular devices with bridging capability available for multipath communications between the first and second networks. A packet scheduler identifies segments of received packets originating from the second network and assigns one or more wireless cellular devices selected from the list to the identified segments. A packet transmitter encapsulates the segments of packets so identified and addresses the encapsulated segments to the assigned wireless cellular devices.

Both live and offline transcoding of media is managed for storage in a cache. Requests for media are made by a client on a network and media taken from the cache and transcoded for delivery to the client. Media is also transcoded and stored in memory during idle request in anticipation of future requests during idle transcoder time between client requests. A prioritizer manages at least offline transcoding requests. A high priority queue operates at a higher priority than the low priority queue. The high priority queue receives live transcoding requests from a client on the network. A low priority queue receives offline transcoding requests. A media transcoder primarily transcodes media in accordance with requests from the high priority queue for delivery to a client on the network and then secondarily transcodes media in accordance with requests from the low priority queue when the high priority queue is empty. According to alternative embodiments the media transcoder transcodes media into segments and to modify frames when necessary to insure that they are decodable without accessing other segments.
