1. A system for simultaneously transmitting program material and data corresponding to the program material, comprising:
- a plurality of program sources;
a transmitter;
a mixing board for routing said program material from a selected one of said program sources to said transmitter by selectively switching among said program sources and providing as an output signal said program material from said selected program source;
program source detection means coupled to said mixing board for providing a program source signal corresponding to said selected program source;
program material recognition means, coupled to said mixing board output signal, for comparing said program material with a database of known program material data and generating a program material identifying signal in response to the results of said comparison; and
a data stream generator, coupled to said program recognition means, to said program source detection means and to said transmitter, for applying a data stream to said transmitter for transmission with the program material responsive to said program material identifying signal and said program source signal.

Abstract
A broadcast system includes a device to compare program material to be transmitted with a database of known material, and to transmit along with the program material data corresponding to that program material. A corresponding receiving system stores the data in memory and displays, at the selection of the user, the data corresponding to the program material. The user selectively stores the data on a magnetic recording card for electronic coupon or other uses.

3. A method of simultaneously transmitting program material and data corresponding to the program material, comprising the steps of:
-
selecting one of a plurality of program sources for said program material; comparing said program material with a database of known program material data; generating a program material identifying signal in response to the results of said step of comparing; applying said program material to a first input of a transmitter; and selectively applying a data stream corresponding to the program material identifying signal to a second input of said transmitter, in response to said steps of selecting and generating. - View Dependent Claims (4)
