<p>While it is well known that from a central signal source such as a radio or CD player the relevant signals can be transmitted for reproduction in the individual building rooms, the invention proposes to use a central multisignal source such as an ordinary PC which on its harddisc may hold many different signal sequences which in a selective manner can be sent for reproduction in the individual rooms. The signal source may also be connected with actually operating radio or video sources, telephone network or internet for selective reproduction in the various rooms. Moreover, the system may comprise priority giving, portable transmitters which, on arrival in the single rooms, will actuate a receiver for achieving a reproduction of signals of a type corresponding to the choice of the higher priority. These transmitters may be housed in remote control units for two-way communication with constitute telephone handsets and units for reception and transmission of E-mail.</p> |
