NFL preseason kicks off with Harris

The NFL will use HD instant replay systems to rule on sideline catches, goal line stands and other critical plays that often are challenged by coaches. Twenty-one years after the NFL first began using instant replay, referees at professional football stadiums will use new HD systems from Harris that provide images five times sharper than previous SD systems.

Each stadium will use Harris NEXIO HD servers, FORCE software (Football Officiating Replay Challenge Expeditor) and routing and distribution equipment that is replacing existing Harris SD instant replay systems that NFL referees have been using since 1999. NFL team owners voted in March 2007 to make instant replay reviews permanent.
