Audio sensors are located in different parts of an arena and are connected to a server by a wireless or wire connection. The sensors are equipped for reception and transmission of audio sounds for selected locations in the arena. The server provides a frequency divided carrier to the respective sensors. The audio sensors are capable of modulating the carrier frequency as a stereophonic sound in the area of the sensor. The server receives, digitizes, and packetizes the stereophonic sensor signals into a plurality of digital streams, each representative of a sensor location in the arena. The audio streams are combined with the video of an event using digital video broadcasting or via a cable system. The viewers are equipped with a control device linked to a TV for a selection of an audio stream by energizing an icon indicative of an audio stream representative of a position in the arena.
