A combination of a radio receiver with a detachable controller is presented. The radio receiver sends either reduced or enhanced metadata about received programming to the controller. A connection from the controller to the receiver carries commands and carries only the reduced set of metadata, such as tuned channel and tuned channel name, from the radio receiver back to the controller. The controller is authorized by the radio receiver sending a radio identifier to the controller, determination of an authentication code at the controller and communication of the determined authentication code back to the radio receiver 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, may be encrypted. Such authorization processing is periodically performed by the radio receiver.

Proprietary radio control head with authentication

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.
