ABSTRACT:
The invention relates to a system for remote control of at least two controllable devices, the system comprising a remote control device (6) with communicating means for communicating to the controllable devices a user-specified command produced by the remote control device. The invention also relates to a method of remote control of at least two controllable devices, the method comprising the step of communicating a user-specified command to the controllable devices (4, 5). The method comprises the further steps of adding the user-specified command a device identifier for identification of at least one of the controllable devices; transmitting the device identifier and the user-specified command, receiving the device identifier and the user-specified command; extracting the device identifier, comparing said extracted device identifier with a further device identifier for identification of the controllable device, refraining from further operation with the received user-specified command if said identifiers do not match, and supplying the user-specified command to the controllable device.
