A television receiver device consistent with certain embodiment is controlled by a remote controller has an infrared receiver that receives control signals from the remote controller. Both sets of blades are connected to an alternator and are operable to rotate the stator and rotor thereof in opposite directions relative to one another, thereby doubling their relative speed. The device uses simple latches, flops and phase-detectors to compare and identify the nature of the clock duty cycle skew. A receiving device receives a digital signal containing the availability of a service, the deterministic mapping corresponding to the service, and the service content, and performs an operation on the service content in accordance with the deterministic mapping.
