Component audio/video system with automatic turn-off of peripheral devices

摘要

A component audio/video system includes a system controller coupled to supply selection and control commands to a plurality of peripheral audio/video devices and to receive status messages therefrom. The devices may be selected to form a number of different recording configurations involving combinations of one or more recording signal sources and one or more devices for recording the signals. The system controller enters one of a number of different control modes for turning power off to the signal sources and recording devices depending on the status messages identifying recording configurations to enable continued recording by some devices when others run out of recording or playback media.
