Abstract: A data communication system for outputting a multimedia source to occupants of a vehicle comprising an emitter unit centrally located within an interior of the vehicle and in close proximity to a headliner of the vehicle wherein the emitter unit is responsive to a data signal to transmit an infrared signal. The emitter unit further includes a source of the infrared signal in a central core of the emitter unit and directs the infrared signal in a radial direction toward an outer perimeter of the emitter unit with a first field angle. A curved deflector located on the outer perimeter of the emitter unit deflects the infrared signal throughout the interior of the vehicle with a second field angle larger than the first field angle.
