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.
