摘要

A signal interface (5) with an acoustic converter like a modem (6) receives remotely transmitted control signals from a portable bi-directional communications device like a mobile telephone (8) or a mini-computer (11) carried around by a person wishing to view. A control device controls a replay appliance (2) by using the control signals. A signal interface connects to a public communications network like an analog or digital telephone network (7).
