Content distribution system and method for optimizing multiplexed transport channels
A content distribution system includes a distribution center, a processor, a switch, and first and second multiplexers. The distribution center receives and applies program content on program channels. The processor identifies subsets of the program channels in response to a respective score associated with the program channels. The switch couples the distribution center to the multiplexers. The switch applies program channels to respective inputs of the first and second multiplexers in response to the processor. A method for optimizing a multiplexed transport channel includes the steps of identifying a set of program channels designated for distribution via the multiplexed transport channel, arranging the set of program channels in subsets, the program channels within a subset grouped in accordance with a viewing score, multiplexing the program channels of the subsets to a respective transport channel and applying the respective transport channels to a distribution medium for delivery to the destination.
1. A method for optimizing a multiplexed transport channel, comprising:
selectively identifying subsets of a plurality of program channels in accordance with a respective viewing score associated with the plurality of program channels, and
applying program channels to respective inputs of a first multiplexer and a second multiplexer in response to the identified subsets of program channels,
wherein a distribution center applies program content on program channels, and
wherein the subsets of the plurality of program channels are selectively identified based on scores responsive to a likelihood that a channel change at a destination will require a tuner to select a program channel that was processed by the other of the first multiplexer and the second multiplexer.
2. The method of claim 1 , wherein identifying a set of program channels comprises identifying program channels available in a content package.
3. The method of claim 1 , further comprising arranging the plurality of program channels in subsets by grouping available program channels into subsets of N members, where N is an integer that corresponds to a capacity of the first or second multiplexer.
4. The method of claim 1 , wherein arranging the plurality of program channels in subsets comprises grouping available program channels into subsets when the viewing score is associated with the destination.
5. The method of claim 1 , wherein arranging the plurality of program channels in subsets comprises grouping available program channels into subsets when the viewing score is based on a number of times content from the respective program channels is viewed.
6. The method of claim 1 , wherein arranging the plurality of program channels in subsets comprises grouping available program channels into subsets when the viewing score is based on a statistical analysis of viewing habits.
7. The method of claim 1 , wherein arranging the plurality of program channels in subsets comprises grouping available program channels into subsets when the viewing score is based on aggregated data for a community.
8. The method of claim 7 , wherein the viewing score is based on aggregated data from the community served by a common node in a distribution network.
9. The method of claim 1 , wherein repeating periodically the arranging, multiplexing and applying.
10. A head-end comprising:
a head-end processor configured to selectively identify subsets of program channels in accordance with a respective score associated with a plurality of program channels, wherein a distribution center applies program content on the plurality of program channels; and
wherein, in response to the identified subsets of the plurality of program channels, a multi-channel switch applies the plurality of program channels to respective inputs of a first multiplexer and a second multiplexer,
wherein the head-end processor selectively identifies the subsets of the plurality of program channels based on scores responsive to a likelihood that a channel change at a destination will require a tuner to select a program channel that was processed by the other of the first multiplexer and the second multiplexer.
11. The head-end of claim 10 , wherein the head-end processor selectively identifies the subsets of the plurality of program channels based on scores responsive to the likelihood that the program content will be viewed.

13. The head-end of claim 10 , wherein the head-end processor selectively identifies the subsets of the plurality of program channels into a subset of M members, where M is an integer that corresponds to a capacity of the second multiplexer.
14. The head-end of claim 10 , wherein the head-end processor selectively identifies the subsets of the plurality of program channels in response to a statistical analysis of viewing habits.
15. The head-end of claim 10 , wherein the head-end processor selectively identifies the subsets of the plurality of program channels in response to aggregated data for a community.
16. The head-end of claim 15 , wherein the aggregated data from a community is collected from a community served by a common node in a distribution network.
17. The head-end of claim 10 , wherein the head-end processor selectively identifies the subsets of the plurality of program channels periodically.
18. The head-end of claim 10 , wherein the head-end processor selectively identifies the subsets of the plurality of program channels aperiodically.
