Abstract

A TV viewer is presented various offers for products and services displayed on his TV screen. Pre-obtained unique product and service codes are generated by the TV program during the offers. The viewer has a remote control device for indicating his acceptance of an offer. An audio beep corresponding to the unique code is transmitted by the program along with the offer. This beep is picked up by a microphone and is transmitted, along with the remote control acceptance indication, by a transmitter located at the viewer'"'"'s location to a nearby repeater station. The transmitted signal is data including an identification of the viewer'"'"'s location as well as the accepted offer code. This data is relayed to a nearby repeater station and then to a central data collection station where the acceptance is processed. A universal IR remote control device is employed that can communicate a viewer'"'"'s selections from TV offer'"'"'s, or can alternately read bar codes from printed media offers at the viewer'"'"'s location for transmission through the system to the central data collection station.

Claims

1. An interactive data system comprising:

at least one response unit where end user'"'"'s are located, the unit having normally received TV programs playing thereat, the programs presenting questions to the end user;

audible beeps, corresponding to unique preselected codes, independent of program identification, being played by the TV program at the same time a corresponding question is posed;

means located at the response unit for

(a) indicating a response to a question;

(b) picking up the audio beep;

(c) generating a unique signal from both the picked up beep, indicative of the response to a particular question, and an identification of the response unit;

(d) transmitting the generated signal to a local area repeater station; and

means located at the repeater station for transmitting data, derived from the signal, to an audience response data center for processing of the data.

2. An interactive data system comprising:

at least one response unit where end user'"'"'s are located, the unit having normally received TV programs playing thereat, the programs presenting questions to the end user;

audible beeps, corresponding to unique preselected codes, independent of program identification, being played by the TV program at the same time a corresponding question is posed;

means located at the response unit for

(a) indicating a response to a question;

(b) picking up the audio beep;

(c) generating a unique signal from both the picked up beep, indicative of the response to a particular question, and an identification of the response unit;

(d) transmitting the generated signal to a local area repeater station; and

means located at the repeater station for transmitting data, derived from the signal, to an audience response data center for processing of the data

wherein printed media is available at the response unit presenting questions to the end user, the media also having unique preselected printed bar codes representing various fixed responses;

the system further including;

a bar code reader for reading selected bar code responses and generating unique corresponding electrical signals therefrom;

answering means for transmitting the electrical signal, along with an identification of the response unit, to a local repeater station;

manual actuation means located at the response unit for gating transmission of the electrical signal through the answering means; and

means located at the repeater station for transmitting data, derived from the signal, to an audience response data center for processing of the data.

3. The interactive data system set forth in claim 2 wherein the answering means further comprises:

means for picked up audio beeps;

a microprocessor having inputs for the bar code reader and the manual actuation means for creating a unique signal, representing a corresponding bar code or audio beeps responses to be transmitted to a repeater station; and

transmitting means connected to the microprocessor for transmitting a coded response at several different frequency signatures during an interval of time.

4. The interactive data system set forth in claim 3 wherein the transmitting means operates a frequency synthesizer connected to the microprocessor, the transmitting means further comprising:

a voltage reference circuit driving a voltage controlled oscillator for producing a carrier frequency;

means for generating a count corresponding to the output frequency of the voltage controlled oscillator;

a frequency number derived from the microprocessor indicative of the carrier frequency;

means for comparing the frequency number with the generated count;

memory means for storing data for a plurality of pulse;

means for transmitting an address from the microprocessor to an input of the memory means for producing the data of the addressed pulse at an output of the memory means;

means for converting the pulse data to analog form;

means for modulating the carrier with the converted pulse, sequential modulations forming frequency signatures as function of time; and

an antenna for transmitting to a repeater station.

5. A method or returning responses from at least one response unit of an interactive data communication system, the method comprising the steps;

establishing at least one response unit site which receives normal TV or radio programs from a party the programs including questions accompanied by an audible beep corresponding to a unique preobtained code from the question;

indicating a response to the question;

picking up the audio beep;

generating a unique signal from the picked up beep, indicative of a response to a particular question as well as an identification of the response unit;

transmitting the generated signal to a local area repeater station; and

transmitting data, derived from the signal, to an audience response data center for processing of the data.

6. A method of data communication comprising the steps:

generating a unique signal by receiving an audible signal from an electronic device;

combining the received audible signal with a unique identifier of a response unit;

communicating the unique signal from the response unit to a local area repeater station;

verifying the unique signal at the local area repeater station; and

communicating the generated signal from the repeater station to a data center for peocessing.
