Abstract

Audio information in several audio channels is supplied via head sets to passengers seated aboard an aircraft in rows of seats including armrests and being distributed along an elongate passenger section inside a metallic fuselage. According to the subject invention, an antenna is run along the elongate passenger section of the aircraft for radio transmission inside such elongate passenger section. Individual antennas are provided for the passenger seats for receiving the latter radio transmission. These receiving antennas are distributed among predetermined armrests of the passenger seats. The audio information to be transmitted is provided in radio frequency channels in a band between 72 and 73 MHz. The distributed receiving antennas are coupled via seated passengers to the transmitting antenna. The radio frequency channels are transmitted in the mentioned band via the transmitting antenna, seated passengers and distributed receiving antennas to the predetermined armrests. Audio information is derived in the audio channels from the transmitted radio frequency channels also in the predetermined armrests. Passengers are individually enabled to select audio information from among the derived audio information in the audio channels. The selected audio information is applied individually to the headsets.
