Abstract

The present invention provides a universal remote control with components interconnected by a bus, permitting separate location of the components. During operation, a control input is received from a user. A control signal representing the control input is transmitted through the bus. The control signal is received from the bus at a location remote from where the control input was received. A radio frequency activation signal is transmitted based on the received control signal.
