Abstract
An information processing system comprising a computer connected to an amplifier in an audio visual (AV) system through an IEEE 1394 serial bus connection. The amplifier has various different types of external terminals for connecting to other AV devices. The computer requests, receives and displays name information on the external terminals from the amplifier. A user of the system can select various AV devices from the name information displayed on the computer. The computer then commands the amplifier to switch to the selected AV device.
