Abstract
An information delivery system provides programming, such as video programming, by dynamically allocating the programming to channel slots, based on the availability of the channel slots. Programming with high viewership statistics is transmitted substantially continuously and programming with lower viewership statistics is transmitted “on-demand” in response to requests by users by way of a subscriber station. The subscriber stations maintain a map, provided by a corresponding session control manager, of currently available and currently transmitted channels. The information delivery system, in a preferred embodiment, takes the form of a Hybrid Fiber Coaxial (HFC) system.
