Sound and video signal apparatus control system for various rooms of dwelling

摘要

The system reproduces audio and/or video signals and controls the operation of the electronic equipment in the individual rooms, (2-4) from a central receiver (9) set up in one room (2). There is a central unit (7) with a control arrangement, and a remote control transmitter (8) for radiating a modulated 2.4 GHz carrier signal. In the other rooms, equipment such as a washing machine (18) and receivers (5,6) for the modulated carrier are connected via the mains (12,23-25) to the broadcast receiver. Remote commands can also be received by an intercom (20) at the front door (19).
