Abstract
Live television broadcast and other information and entertainment programs, e.g., videos-on-demand (VOD), are provided to a user through a communications network, e.g., a cable network. A processing unit is employed at an headend of the communications network to respond to user requests for PVR-like functions, e.g., pausing, rewinding and fast-forwarding, to be performed on the program content being viewed. The processing unit in accordance with the invention causes a delivery of an appropriate version of the program content to meet such user requests.
