Abstract

A supplemental audio content system is for providing supplemental audio content to movie patrons during playing of a motion picture film and associated soundtrack in a cinema of cineplex including a plurality of individual cinemas. The system may include a player for playing supplemental audio content during playing of the motion picture and associated soundtrack, and a wireless transmitter connected to the supplemental audio content player. An earphone may be worn by the movie patron, and the earphone may be connected to a wireless receiver to cooperate with the wireless transmitter to deliver supplemental audio content to the at least one movie patron. The wireless transmitter and wireless receiver preferably have operating characteristics to avoid interference with respective supplemental audio content systems for other cinemas of the cineplex.
