    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.

    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 thereof for handing off a media session are described. In one embodiment, a first media segment is forwarded to a client node. The first media segment includes a portion of an item of media content stored in lieu of storing the item of media content in its entirety. The item of media content is segmented according to segmentation characteristics. Handoff information used for transferring the media session to another server node is specified. The handoff of the media session to the other server node occurs when the forwarding of the first media segment is completed, such that the handoff occurs between media segments.

    摘要： A method of operating a data processing system having a main memory divided into memory pages that are swapped into and out of main memory when the main memory becomes short. The data processing system has an operating system that sends page store commands specifying memory pages to be stored in a swap file and page retrieve commands specifying memory pages to be retrieved from the swap file and stored in the main memory. The present invention provides a swap driver that utilizes compression code for converting one of the memory pages that is to be swapped out of main memory to a compressed memory page. The data processing memory includes a compressed page region that is used to store the compressed memory pages. A page table in the compressed page region specifies the location of each compressed page and the page address corresponding to that page. The swap driver compresses at least one of the memory pages specified in one of the page store commands to provide a corresponding compressed memory page and causes that compressed memory page to be stored in the compressed page region. The swap driver also searches the page table for a page identified in one of the retrieve commands. The swap driver causes that page to be moved to a corresponding area of main memory after decompressing the page if the swap driver finds an entry in the page table indicating that the page is stored in the compressed page region.

    摘要： One embodiment of the invention includes a method for managing a streaming media service. The method includes receiving a request for a streaming media service from a client and the streaming media service includes a media service component. A service location manager is selected to which to provide the request from a plurality of service location managers. Additionally, a service provider is selected to which to assign the media service component from a plurality of service providers of a network. Furthermore, the service provider is informed of the assignment to perform the media service component. The service provider is caused to prepare to perform the streaming media service on streaming media. Moreover, information is used to determine whether to initiate a handoff of the streaming media service from the service provider to another service provider. If it is determined to initiate the handoff, the handoff is initiated.
