Enhanced pay per view system
First Claim
1. A pay-per-view system, comprising:
- a conductor having a plurality of pay-per-view programs that are available for selection by a subscriber;
each of said plurality of pay-per-view programs is represented by respective pay-per-view program signals, the plurality of pay-per-view program signals are multiplexed together and transmitted via said conductor;
a bi-directional local distribution area cable;
a plurality of set top boxes each having a bi-directional connection to said bi-directional local distribution area cable, each of said plurality of set top boxes having means for selecting a pay-per-view program from said plurality of pay-per-view programs;
a plurality of demultiplexers, each of said demultiplexers demultiplexing program signals of a program that has been selected by a subscriber from said plurality of pay-per-view programs and converting each of said demultiplexed program signals into respective analog television signals;
each of said demultiplexers having;
an input connected to said conductor;
an output for transmitting respective analog television signals; and
a control input for controlling the demultiplexing of the plurality of multiplexed pay-per-view program signals to demultiplex its respective pay-per-view program therefrom;
a controller connected to each of said demultiplexers for individually controlling which pay-per-view program signals are demultiplexed thereby;
a plurality of frequency modulators, each having an input connected to a respective output of said plurality of demultiplexers for receiving the respective analog television signals therefrom, means for modulating the respective analog television signals to a specific channel, and an output for transmitting the modulated analog television signals;
a combiner having a plurality of inputs, each connected to an output of a respective frequency modulator for combining the modulated analog television signals in their respective channels;
said combiner transmitting this combined signal via a bi-directional port thereof to said local distribution area cable;
each of said plurality of set top boxes having means for communicating its respective selected program selection by said bi-directional local area distribution cable to said controller so said controller can control one of said plurality of demultiplexers to demultiplex said selected pay-per-view program;
each of said plurality of set top boxes having an output connected to a respective television equipment; and
each set top box converting the respective modulated analog television signals of its respective selected pay-per-view program to signals that may be received on the respective television equipment connected to the set top box;
wherein said selected pay-per-view program is switched to a channel of the local distribution area cable contemporaneously with its selection.

Abstract
A pay-per-view system for a cable television network that gives the subscribers a greatly enhanced variety of viewing choices. The system uses an interactive set top box for the subscribers to forward their choices for viewing. Since the pay-per-view viewing choices are made interactively from a wide variety of selections, the chances of a subscriber finding something he or she wants to pay to watch are considerably improved. The interactive choices are forwarded to an intelligent video switch. This switch takes the first N programs requested and assigns N programmable selectors to select N programs from a much greater number (M) of possible programs and switches these N programs onto N frequency multiplexed channels on a standard television cable. If the M possible programs are delivered to the video switch in ATM packets, the programmable selectors are ATM packet demultiplexers, and if the M possible programs are delivered to the video switch as frequency multiplexed channels, the programmable selectors are programmable radio frequency tuners. This system will make the subscribers happier because it gives them more choices for viewing, and will make the pay-per-view operators happier because it should lead to increased revenue from an increase in the number of pay-per-view programs watched.
