CATV PAY PER VIEW INTERDICTION SYSTEM METHOD AND APPARATUS |
摘要 |
A CATV system includes a headend (10) which transmits programming including pay-per-view programming and a cable distribution system which distributes the programming. Service providing equipment (20) is coupled to the cable distribution system for supplying the programming to at least one subscriber. A subscriber terminal (500) is coupled to the service providing equipement (20) over a communication link. The subscriber terminal (500) includes an input device (520) for inputting subscribersupplied signals indicative of a pay-per-view event to generate a message. A transmitter (540) responsive to the subscriber-suppli-ed signals transmits the message to the service providing equipment (20) over the communication link. The service providing equipment (20) includes a service apparatus (400) coupled between first and second diplexers (295; 395). The diplexers (295; 395) separate the transmission path between the headend (10) and the subscriber terminal into downstream or forward and upstream or reverse transmission paths.
