What does IRC mean on my TV?
Incremental Related Carriers
Incremental Related Carriers (IRC) – A method of spacing and transmitting television channels on a cable television system that prevents interference among the channels and reduces a form of distortion. The channels are spaced at 6-MHz intervals, with all carrier frequencies harmonically related to a common reference.
