Address assignment and control of a single connection terminal device on a bus

摘要

A bus connects a plurality of electronic devices. The address of a prescribed electronic device having a single connection-terminal is assigned based on parent/child considerations. The prescribed device having a single connection terminal is controlled by a designated device so that other devices on the bus cannot directly communicate with the prescribed device other than through the designated device. In one embodiment, the bus is a P1394 audio/visual serial bus, the prescribed device is a camcorder, and the designated device is a VCR.
