AbstractIn a pay per view entertainment system, prerecorded entertainment such as musical works are distributed to subscribers over a cable network. The subscribers are able to listen to edited versions or previews of the complete musical works and to select desired musical works for recording. Before the musical work is recorded on a special receiver, the subscriber is billed for the service.
