$BRKK The first product introduced using this technology is the RefCam HD-I. The RefCam HD-I is a COFDM (Coded Orthogonal Frequency Division Multiplexing), HD video transmitter with an integrated high definition camera. The RefCam is designed for broadcast applications, using the best camera available in the United States. It differs from other sports cameras in that it is not a strap-on, does not require bulky battery packs – its easy to clip on battery module gives users over an hour of continuous use and can easily be replaced during play – and transmits directly from an integrated circuit board within the camera to broadcast live to TV viewers. The entire unit is only 2 inches by 6 inches, integrated into the helmet worn by referees and provides a point of view never before seen on TV or in professional sports.
