Patent attributes
An interactive radio system includes a broadcast radio station and an interactive radio device wherein the interactive radio device sends feedback data to the broadcaster. In various embodiments, the broadcast radio station can broadcast an enhanced radio signal that includes control data to instruct the interactive radio device on how to collect feedback data. The feedback data can be collected directly by posing input requests to a listener or indirectly by transparently monitoring the listener's activities. Feedback is provided back to the broadcaster over a backchannel by which data can be sent from a listener back to the broadcast station or another data gathering source. Backchannel routes can be provided by any of a host of communications technologies such as the Internet and/or wireless networks such as cellular networks, Bluetooth, 802.11 networks, and the like.
