Abstract
Abstract An impulse pay-per-view system wherein a number of downloadable transactions may be utilized to effect increased control and diversity is disclosed. A preview time/free transaction permits a system subscriber to view portions of a pay-per-view event without purchasing the event. A security transaction sent while a pay-per-view event is active may be used to prevent a subscriber from receiving events which have not been purchased. A telephone number transaction may include a special character representing an instruction to pause between the dialing of selected digits. A viewer statistic transaction may be use dot instruct a subscriber to record the channel he is viewing. Finally, a subscriber may pre-buy pay-preview events in order to facilitate VCR recording of the events while he is asleep or away from home.
