A system and method are described for controlling a plurality of devices (150) by a remote control apparatus (105). The remote control apparatus (105) transmits a same sequence of commands individually to each of the plurality of devices (150) to execute a relative increase or decrease of a parameter thereof with a certain value. There is two-way communication between the remote control apparatus (105) and the devices (150). The devices (150) acknowledge the correct reception of a command by transmitting an acknowledgement message to the remote control apparatus (105). The remote control apparatus (105) repeats the transmission of a command to a device (150) in case of not receiving an acknowledgement message from the device (150). In this way, it is guaranteed that all controlled devices (150) receive the same commands and the controlled parameters thereof are kept in synchronization. |
