Abstract

A computer system provides streaming media to a plurality of clients over a network. The system includes a proxy module that forwards streaming media from a first streaming media source to a network server module that is communicating to the plurality of client terminals. The proxy module is comunicatable with the network server module to be signaled a switch request. In response to the switch request, the proxy module forwards streaming media from a second streaming media source to the network server module while the network server module is signaling streaming media from the first streaming media source to the plurality of client terminals.

Claims

1. A system for providing streaming media to a plurality of clients over a network, the system comprising:

a proxy that forwards streaming media from a first streaming media source to a network server module, the proxy being communicable with the network server module to be signaled a switch request requesting streaming media from a second streaming media source, and in response to the switch request, the proxy forwarding streaming media from the second streaming media source to the network server module to facilitate seamless transition from the first streaming media source to the second streaming media source.

2. The system of claim 1, wherein the proxy forwards the streaming media from the second streaming media source to the network server module while the network server module signals streaming media from the first streaming media source to the plurality of client terminals.

3. The system of claim 1, further comprising a memory that stores streaming media forwarded from the proxy for the network server module, the network server module accessing the memory to receive the streaming media forwarded from the proxy.

4. The system of claim 3, wherein the proxy forwards the streaming media from the second streaming media source to the network server module while the network server module is accessing the streaming media from the first streaming media source from the memory.

5. The system of claim 1, wherein a plurality of streaming media sources coupled to the network each include a proxy to receive streaming media from other streaming media sources to facilitate large scale proxy streaming media delivery.

6. A computer system for providing streaming media to a plurality of clients over a network, the system comprising:

a proxy that forwards streaming media from a first streaming media source to a network server module that is communicating to the plurality of client terminals, the proxy being communicable with the network server module to be signaled a switch request, and in response to the switch request, the proxy forwarding streaming media from a second streaming media source to the network server module while the network server module is signaling streaming media from the first streaming media source to the plurality of client terminals.

7. The system of claim 6, further comprising a memory that stores streaming media forwarded from the proxy for the network server module, the network server module accessing the memory to receive the streaming media forwarded from the proxy.

8. The system of claim 7, wherein the proxy forwards the streaming media from the second streaming media source to the network server module while the network server module is accessing the streaming media from the first streaming media source from the memory.

9. The system of claim 6, wherein a plurality of streaming media sources coupled to the network each include a proxy to receive streaming media from other streaming media sources to facilitate large scale proxy streaming media delivery.

10. A method for providing streaming media to a plurality of clients over a network, comprising:

at a proxy, receiving a switch request requesting streaming media from a second streaming media source; and

in response to said switch request, the proxy forwarding streaming media from the second streaming media source to a network server module to facilitate seamless transition on a channel from a first streaming media source to the second streaming media source.

11. A method for providing streaming media to a plurality of clients over a network, comprising:

forwarding streaming media from a first streaming media source to a network server module using a proxy;

receiving a switch request at the proxy requesting streaming media from a second streaming media source; and

in response to the switch request, the proxy forwarding streaming media from the second streaming media source to a network server module to facilitate seamless transition from the first streaming media source to the second streaming media source.

12. A method for providing streaming media to a plurality of clients over a network, comprising:

forwarding streaming media from a first streaming media source to a network server module using a proxy;

receiving a switch request at the proxy requesting streaming media from a second streaming media source; and

in response to the switch request, the proxy forwarding streaming media from the second streaming media source to the network server module while the network server module is signaling streaming media from the first streaming media source to the plurality of client terminals.
