    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： Various embodiments of the invention relate to a glaucoma valve, a casing for containing a glaucoma valve and a glaucoma drainage device comprising the glaucoma valve and/or the casing. The valve includes a flow channel having an inlet and an outlet and a valve member connected to the outlet of the flow channel. The valve member may be formed from a degradable polymer or a combination of degradable polymer and non-degradable polymer. Various embodiments of the invention relate to a glaucoma valve, the valve having a first flow channel. The interior of the first flow channel may be coated with a degradable polymer, such that in use, the polymer degrades to allow a greater flow of fluid through the flow channel. In some embodiments, the valve includes a second flow channel, which may be arranged in parallel to the first flow channel. The first flow channel may be completely sealed with the polymer such that in use, the polymer degrades to allow fluid to flow through the first flow channel. Various embodiments relate to a casing for containing a glaucoma valve. The casing may be formed from a degradable polymer, such as a biodegradable polymer.

    摘要： 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.
