A combination of a radio receiver with a detachable controller that
determine sends either reduced or enhanced metadata about received
programming to the detachable controller based upon periodic
authorization. A connection from the detachable control device to the
radio receiver carries commands to the radio receiver and carries only
the reduced set of metadata, such as tuned channel and tuned channel
name, from the radio receiver to the controller. The controller is
authorized by sending a radio identifier from the radio receiver to the
control device, determination of an authentication code at the controller
and communication of the determined authentication code back to the
controller for validation. Upon validation, an enhanced set of metadata,
including song title and artist, is sent to the controller. The enhanced
metadata, the reduced metadata, or both, are optionally able to be
encrypted. The radio receiver periodically performs this authorization
processing.
