A method and device for three-dimensional graphics to two-dimensional video encoding. A three-dimensional model representing at least one three-dimensional object is received. The three-dimensional model is rendered into a two-dimensional frame. Composition information for the two-dimensional frame is extracted from the three-dimensional model. A bit stream is encoded based on the two-dimensional frame and the composition information.

A method for streaming video data. Video data is received. At least one frame of the video data is segmented into a plurality of regions. Video data corresponding to a first region of the plurality of regions is transmitted over a network. The video data corresponding to a second region of the plurality of regions is modified according to interactive input. The video data corresponding to a modified version of the second region is transmitted over the network.

Embodiments of the invention provide a system and method for transferring data on a data network using multiple paths. In one embodiment, data is transferred across a default path of a network. Next, a data loss rate is determined on the default path. When the data loss rate on the default path exceeds a first threshold value, a data loss rate is determined on a first alternate path. Provided the data loss rate on the first alternate path is less than a second threshold value, a first portion of the data is transferred to the first alternate path. Moreover, additional portions of data are transferred to the first alternate path until the data loss rate on the first alternate path meets or exceeds the second threshold value.

A graphics to video encoder is disclosed. The encoder comprises a client image constructor that receives client input and constructs client image frames based on the client input. A scene integrator is coupled to the client image constructor. The scene integrator accesses base image frames and integrates client image frames with base image frames to generate client scene frames. The graphics to video encoder also has coupled to the scene integrator a video encoder that encodes and outputs the client scene frames as a video bitstream.

A method for enhancing transmission quality of streaming media. A first bandwidth for a first communication link and a second bandwidth for a second communication link of a network are determined. Provided the first bandwidth is greater than the second bandwidth, a first excess bandwidth is utilized to improve transmission quality in the first communication link, wherein said the excess bandwidth is related to a difference of the first bandwidth minus the second bandwidth. Provided the second bandwidth is greater than the first bandwidth, a second excess bandwidth is utilized to improve transmission quality in the second communication link, wherein the second excess bandwidth is related to a difference of the second bandwidth minus the first bandwidth.

A method and system for streaming media data to a fixed client and/or a mobile client. In one method embodiment, the present invention recites encoding media data to be streamed to a client into a first multiple description bitstream and into a second multiple description bitstream. The present method then determines the appropriate plurality of servers from a network of servers onto which the first and second multiple description bitstreams should be distributed. The present embodiment then recites distributing the first and second multiple description bitstreams to the appropriate plurality of servers positioned at intermediate nodes throughout a network such that a client is provided with access to the media data via a plurality of transmission paths. The present method is also well suited to redistribution of multiple description bitstreams to servers based upon time-varying demand, client movement, and the like.

A method for encoding a plurality of video frames of a single data stream at a plurality of encoding rates is provided. The method includes accessing a first video frame associated with the single data stream and encoding the first video frame at a first encoding rate. The method further includes accessing a second video frame associated with the single data stream and encoding the second video frame at a second encoding rate.
