Audio visual system having a serial bus for identifying devices connected to the external terminals of an amplifier in the system

An information processing method in an information processing system comprised of a main information processing device controlled by a control device through a communication means, and a plurality of sub-information processing devices connected to said main information processing device respectively, said communication means being a serial bus, said main information processing device being an amplifier, and said control device being a computer;

• comprising the steps of:
• memorizing name data indicating the names of a plurality of terminals in said main information processing device, which are provided to connect to said plurality of sub-information processing devices with a corresponding plurality of connecting means, in a memory means,
• wherein the name data includes unique manufacturer and chip numbers;
• at least one of said connecting means being said communication means;
• changing the name data indicating the names of said terminals memorized in said memory means, according to a user's input operation;
• transmitting said name data to said control device from said main information processing device through the communication means;
• receiving said name data, which is transmitted from said main information processing device through the communication means, by said control device;
• and
• displaying the name of said terminals on a display means based on said name data.
