The link type,transmission structure,infrared link scheme,infrared transceiver and infrared controller of the short-range infrared carrier which is suitable to develop indoor multimedia equipment are discussed.The limitation of the applicaton of infrared communication protochols and infrared techniques in wireless multimedia equipment is analyzed.A multimedia LAN which is established on the basis of the current LAN and is centered arround infrared transceiver base station is presented. Finally,an idea that the short-range infrared wireless communication is used to develop indoor multimedia equipmenrt is proposed.
