1. A system for remote control of at least two like controllable devices, the system comprising:

  • a) a remote control device comprising;

    a remote control input means for inputting a user-specified command for controlling the controllable devices; and

    a remote control transmitting means adapted to transmit the user-specified command;

    b) a coding device comprising;

    a coding input means for receiving the user-specified command from the remote control device;

    a coding means designed to add to the user-specified command a device identifier for identification of at least one of the controllable devices;

    a coding transmitting means adapted to transmit the device identifier and the user-specified command in combination;

    c) the like controllable devices each comprising;

    a receiving means adapted to receive the device identifier and the user-specified command in combination;

    a decoding means designed (1) to extract the device identifier, (2) to compare said extracted device identifier with a further device identifier for identification of the controllable device, and (3) to refrain from further operation with the received user-specified command if said identifiers do not match;

    an output means for supplying the user-specified command if said identifiers do match;

    wherein the remote control device and the coding device are separate devices which are selectively interconnectable and disconnectable, the remote control device functioning to transmit the user-specified command to controllable devices when the coding device is disconnected and the coding device functioning to transmit the user-specified command when the remote control device and the coding device are connected.
