摘要： 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.

摘要： A method for performing a soft-handoff in a mobile streaming media system, and a method for performing a hard-handoff in a mobile streaming media system are is disclosed. In the soft-handoff embodiment, the present invention detects that a channel quality between a mobile client and a first base station remains above a drop threshold and that a channel quality between the mobile client and a second base station increases from below to above an add threshold. The present embodiment then sends a first multiple description bitstream from the first base station to the mobile client and sends a complementary second multiple description bitstream from the second base station to the mobile client. This method thereby provides improved utilization of wireless bandwidth during soft-handoffs, in contrast to conventional systems where the same bitstream is transmitted from each base station. In both the cases of soft-handoffs and hard-handoffs, when a mobile client enters a cell whose base station has no free capacity, the base station may prevent call dropping by reducing the number of descriptions being served to the existing clients and thereby providing capacity (at least one description) for the new client. These methods provide improved utilization of wireless bandwidth during soft-handoffs, and reduced probability of service disruption during both soft-handoffs and hard-handoffs.

摘要： 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.

摘要： A method and system for streaming media data to a mobile client device. Using information such as the previous locations of the mobile client device, a prediction is made of a future location of the client device. A server servicing the predicted location, such as the server closest to the predicted location, is identified. This server is informed of the impending arrival of the mobile device into the area serviced by the server. The server can thus obtain ahead of time the media stream needed for the client, so that the data are available to the client without disruption when the client moves to the predicted location. To account for uncertainty in the prediction, the data can also be directed to other servers that can service the predicted location.

摘要： 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.

摘要： 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.

摘要： 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.
