We claim:

1. A subscriber terminal for use in an off premises CATV system with impulse pay-per-view capability including a headend, at least one feeder cable connected to said headend, and an off premises unit connected to said feeder cable and coupled to said subscriber terminal over a communication link, said subscriber terminal comprising:

inputting means for inputting subscriber-supplied signals indicative of a pay-per-view event to generate a message; and

transmitting means responsive to the subscriber-supplied signals for periodically transmitting the message within a predetermined period of time to said off premises unit over said communication link.

2. The subscriber terminal in accordance with claim 1 wherein said communication link comprises a one-way communication link.

3. The subscriber terminal in accordance with claim 1 wherein said means for periodically transmitting includes means for periodically transmitting the message at random times within the predetermined period of time.

4. An off premises CATV system comprising:

a headend for transmitting programming including pay-per-view programming;

cable distribution means for distributing the programming;

an off premises unit coupled to said cable distribution means for supplying the programming to at least one subscriber;

a subscriber terminal coupled to said off premises unit by a communication link, said subscriber terminal including inputting means for inputting subscriber-supplied signals indicative of a pay-per-view event to generate a message;

first transmitting means responsive to the subscriber-supplied signals for transmitting the message from said subscriber terminal to said off premises unit over said communication link;

a memory at said off premises unit for storing the message from said subscriber terminal; and

second transmitting means for transmitting the message stored in said memory to said headend.

5. The off premises CATV system in accordance with claim 4 wherein said communication link comprises a one-way communication link.

6. The off premises CATV system in accordance with claim 4 wherein said first transmitting means includes means for periodically transmitting the message within a predetermined period of time.

7. The off premises CATV system in accordance with claim 6 wherein said means for periodically transmitting includes means for periodically transmitting the message at random times within the predetermined period of time.

8. A method of providing impulse pay-per-view capability in a CATV system including a headend for providing programming including pay-per-view programming, at least one feeder cable connected to said headend for distributing the programming, an off premises unit connected to said feeder cable for receiving the programming and distributing the programming to at least one subscriber, and a subscriber terminal coupled to said off premises unit over a communication link, the method comprising the steps of:

inputting subscriber-supplied signals indicative of a pay-per-view event into said subscriber terminal to generate a message; and

transmitting the message periodically within a predetermined period of time to said off premises unit over said communication link in response to the input of said subscriber-supplied signals.

9. The method in accordance with claim 8 wherein said communication link comprises a one-way communication link.

10. The method in accordance with claim 8 wherein the step of transmitting comprises periodically transmitting the message at random times within the predetermined period of time.

11. The off premises CATV system in accordance with claim 4 wherein said memory is a non-volatile memory.

12. A method of providing impulse pay-per-view capability in a CATV system including a headend for providing programming incl
