Abstract
An audio/video (AV) information transaction system includes AV appliances installed in individual rooms, controllers associated with the AV appliances and a host computer which is linked with the controllers through a local area network (LAN), thereby forming a computer network. The host computer transfers control programs to the controllers. A controller in a room which runs the received control program sends a command signal of the demand of AV output reception to other controller in other room over the LAN cable, and the receiving controller operates the associated AV appliance and delivers the output AV signal to the demanding controller over the LAN cable.
