The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method comprising:
buffering a plurality of video streams within a buffer of a video server; and
generating a unicast video output and a multicast video output at the buffer.
2. The method of claim 1, wherein the buffer is associated with a requested channel and wherein the unicast video output and the multicast video output are generated based on the plurality of video streams.
3. The method of claim 1, further comprising:
sending the unicast video output for the requested channel from the video server to a first set top box of a plurality of set top boxes,
wherein the video server continues sending the unicast video output for the requested channel until the first set top box has been joined to a multicast group associated with the requested channel.
4. The method of claim 3, further comprising:
sending the multicast video output to the first set top box after the first set top box has been joined to the multicast group.
5. The method of claim 1, further comprising sending the multicast video output to a plurality of set top boxes.
6. The method of claim 1, wherein the plurality of video streams is received via multicast from an acquisition server coupled to the video server through a network.
7. The method of claim 3, wherein the buffer comprises a fast channel change buffer operative to receive and buffer a video input and wherein the fast channel change buffer is operative to provide the multicast video output.
8. The method of claim 7, wherein the fast channel change buffer includes a multicast replication point operative to provide the multicast video output associated with a multicast group to the plurality of set top boxes including the first set top box.
9. The method of claim 8, wherein the multicast replication point is distinct from a unicast video output point of the buffer.
10. The method of claim 9, wherein the multicast replication point is at a beginning portion of the fast channel change buffer and the unicast video output point is at an end portion of the fast channel change buffer.
11. The method of claim 7, wherein the video server is further configured to use the fast channel change buffer as an error correction buffer.
12. A server comprising:
a buffer;
a processor;
a memory accessible by the processor; and
a computer program embedded within the memory, the computer program comprising:
instructions executable by the processor to buffer a plurality of video streams within the buffer; and
instructions executable by the processor to generate a unicast video output and a multicast video output at the buffer.
13. The server of claim 12, wherein the computer program further comprises instructions executable by the processor to receive a channel change request from a set top box.
14. The server of claim 13, wherein the computer program further comprises:
instructions executable by the processor to send the unicast video output for the requested channel from the server to the set top box, wherein the server continues sending the unicast video output for the requested channel until the set top box has been joined to a multicast group associated with the requested channel; and
instructions executable by the processor to send the multicast video output to the set top box after the set top box has been joined to the multicast group.
15. The server of claim 12, wherein the buffer comprises a fast channel change buffer operative to receive and buffer a video input, and wherein the fast channel change buffer is operative to provide the multicast video output.
16. The server of claim 15, wherein the fast channel change buffer further comprises a multicast replication point operative to provide the multicast video output associated with a multicast group to a plurality of set top boxes.
17. A method comprising:
sending a channel change request corresponding to a selected channel from a set top box to a first server;
determining, at the set top box, whether the first server is in service;
when the first server is in service, receiving a unicast video output from a buffer at the first server prior to joining a multicast group associated with the selected channel; and
receiving a multicast video output from a multicast replication point of the buffer after joining the multicast group associated with the selected channel.
18. The method of claim 17, wherein the unicast video output and the multicast video output are both based on a buffered video stream.
19. The method of claim 17, further comprising:
when the first server is not in service, transmitting a request for the selected channel to an acquisition server that provides a multicast video stream to the first server;
receiving the multicast video stream from the acquisition server.
20. The method of claim 19, further comprising receiving the multicast video stream from the first server after the first server has returned to service.
