1. A transmitter station apparatus for processing signals and communicating mass medium program materials to present at each of a plurality of receiver stations a presentation of (1) one of a broadcast and a cablecast program and (2) a receiver specific computer processed datum related to the content of said program, with each of said plurality of receiver stations having an output device for receiving and delivering said program and other information, each of said plurality of receiver stations also having a computer with a specific memory location, said computer operatively connected to said output device for storing and outputting information to said output device, said computer controlling, prior to communication of an information transmission comprising said program and at least one control signal, the storage of receiver specific information distinct to the receiver station, said transmitter station apparatus comprising:

  • one of a broadcast and a cablecast transmitter for communicating to said plurality of receiver stations said information transmission;

    a program input receiver operatively connected to said transmitter for communicating said program to said transmitter;

    at least one of a first memory and a first recorder operatively connected to said transmitter for storing and communicating said at least one control signal which at each of said plurality of receiver stations operates to perform at least one of;

    (1) generating with said computer said receiver specific datum by processing said receiver specific information in accordance with said at least one control signal; and

    (2) selecting said receiver specific datum with said computer from a plurality of receiver specific data by processing said receiver specific information in accordance with said at least one control signal, said plurality of receiver specific data being prestored at said plurality of receiver stations;

    selecting said specific memory location with said computer for placement of said receiver specific datum by processing said receiver specific information in accordance with said at least one control signal; and

    an input device operatively connected to said at least one of said first memory and said first recorder for causing said at least one of said first memory and said first recorder to communicate said control signal at a specific time to said transmitter, thereby to communicate said program and said control signal to said plurality of receiver stations and cause each of said plurality of receiver stations to deliver said program at said output device, process said receiver specific information, place said receiver specific datum at said memory location, and deliver said presentation of said one of a broadcast and a cablecast program and said receiver specific datum at said output device.
