Wireless interactive transaction system
First Claim
1. A method for performing a wireless interactive transaction using a wireless telephone handset comprising the steps of:
- forming a digitally coded query signal which is separate from an audio-band content to be broadcast;
converting said digitally coded query signal into an audio-band query signal;
injecting said audio-band query signal into said audio-band content to produce a combined audio-band signal;
transmitting said combined audio-band signal on an audio channel;
receiving said combined audio-band signal from said audio channel by a device which is separate from the wireless telephone handset;
conveying said received combined audio-band signal from said separate device to said wireless telephone handset;
processing said combined audio-band signal conveyed from said separate device at the wireless telephone handset to reproduce the digitally coded query signal and to decode instructions coded therein when forming said digitally coded query signal; and
controlling said wireless telephone handset to respond to said decoded instructions.

Abstract
A method and system for enabling automatic or semi-automatic interactive responses to electronic queries using audio-band coded data as the query medium and wireless data communications as the response medium. Typical applications include interactive broadcast advertising in which a coded data query is embedded in a broadcast audio channel and reproduced as an acoustic audio signal in a broadcast receiver. This acoustic signal is then detected by the microphone of a wireless telephone and decoded and processed by the electronic circuitry of said wireless telephone. Upon a pre-determined further action by the user, the decoded and processed query data causes the wireless telephone to transmit a pre-determined message. The pre-determined message includes information which instructs the serving wireless network to properly route the message so that it effectively provides a response to the original query.

17. A system for performing a wireless interactive transaction using a wireless telephone handset, comprising:
-
an interface for forming a digitally coded query signal which is separate from an audio-band content to be broadcast and converting said digitally coded query signal into an audio-band query signal;
a subsystem for injecting said audio-band query signal into said audio-band content to produce a combined audio-band signal;
a transmitter for transmitting said combined audio-band signal on an audio channel;
a receiver for receiving said combined audio-band signal from said audio channel by a device which is separate from the wireless telephone handset;
a device for conveying said received combined audio-band signal from said separate device to said wireless telephone handset; and
a microcomputer included in said wireless telephone handset for processing said combined audio-band signal conveyed from said separate device to reproduce the digitally coded query signal and to decode instructions coded therein when forming said digitally coded query signal and for controlling said wireless telephone handset to respond to said decoded instructions. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
