Abstract

In a cable television system, a specific carrier is assigned to deliver programming content of a program channel to a service area for a period, defined as a function of viewership of the program channel during that period. For example, the program channel is assigned the specific carrier during the time when it has a generally strong viewership. Otherwise, the program channel is assigned a carrier on an as needed basis, i.e., only when one or more subscribers in the service area request such a program channel. Viewing statistics are generated to identify viewership patterns or viewing habits of the subscribers in the service area with respect to a given program channel. In another embodiment, based on the viewing statistics, popular and unpopular programs, program elements, program lineups, program channels are identified on a temporal and/or regional basis.
