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.

Channel assignment for access points (APs) in a wireless network includes determining at least one of a MaxSum and a MaxMin, and determining a channel assignment for the APs based on at least one of the MaxSum and the MaxMin. The MaxSum is a maximization of a system throughput and the system throughput is a sum of throughput of nodes in the network. The MaxMin is a maximization of a minimum throughput of a set of AP-client links in the network. The AP-client link is a link between an AP and a client associated with the AP.

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.

Data paths extending to a first receiver from a plurality of data supply sources are each capable of supplying the same stream data. When providing the stream data to the first receiver rate-distortion of the data paths is optimized. Clocks asynchronous with each other per data path are set so as to attain the rate-distortion optimization.

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 handing off to a second server, in either a fixed or mobile streaming media system, a multiple description streaming session between a first server and either a fixed or mobile client. In one embodiment, the present invention recites selecting a second server to receive a handoff of a multiple description streaming media session between the first server and the client. In this embodiment, the multiple description streaming media session is comprised of a first multiple description bitstream and a second multiple description bitstream. The present embodiment further recites receiving at the second server, the second multiple description bitstream for streaming to the client. This embodiment further recites sending the second multiple description bitstream from the second server to the client.

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 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 assigning servers to provide multiple description bitstreams to a mobile client (in a mobile client environment) or to a fixed client (in a fixed client environment). In one embodiment, the present invention, upon receiving a request from a mobile client to have media data streamed thereto, analyzes a plurality of servers to determine a first candidate server for providing a first multiple description bitstream to the base station along a first path. The present method also determines a second candidate server for providing a second multiple description bitstream to the base station along a second path. The present method then sends a request to the first candidate server to provide the first multiple description bitstream to a mobile client through a base station along the first path, and also sends a request to the second candidate server to provide the second multiple description bitstream to the mobile client through the same base station along a second path. In another embodiment, there are two separate paths from two separate servers to two separate base stations and then from each base station there is a separate path to the mobile client. In still another embodiment, there are two paths from a single server to two separate base stations and then from each base station there is a separate path to the mobile client. In one fixed client embodiment, the present invention is able to assign a plurality of servers to provide a plurality of MD bitstreams to the fixed client.
