Remote control of a plurality of devices
First Claim
1. A remote control apparatus for controlling a plurality of devices, the remote control apparatus comprising:
- a transmitter transmitting a sequence of commands individually to each of the plurality of devices, each of the commands of the sequence instructing the respective device to execute an increase or decrease of a parameter thereof with a certain value; and
a controller generating the commands and controlling the transmission of the sequence of commands, the controller controlling the transmitter to repeat the transmission of a command to a device in case of not receiving an acknowledgement message from the device, the repeat of the transmission of the command to the device based upon a function of the time period needed to transmit one or more of the commands.

Abstract
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.

12. A remote control apparatus for controlling a plurality of devices, the remote control apparatus comprising:
-
a processor having memory with instructions for controlling the transmission of a sequence of commands through a transmitter, the processor configured by the instruction to transmit the sequence of commands individually to each of the plurality of devices; each of the commands of the sequence instructing the respective device to execute an increase or decrease of a parameter for the respective device by a certain value; the processor configured by the instruction to generate the commands and control the transmission of the sequence of commands, the processor controlling the transmitter to repeat the transmission of a command to a device in case of not receiving an acknowledgement message from the device, the increase or decrease of the parameter for the respective device modified as a function of the time period needed to transmit one or more commands of the sequence of commands.

13. A remote control apparatus for controlling a plurality of devices, the remote control apparatus comprising:
-
a processor having memory with instructions for controlling the transmission of a sequence of commands through a transmitter, the processor configured by the instruction to transmit the sequence of commands individually to each of the plurality of devices; each of the commands of the sequence instructing the respective device to execute an increase or decrease of a parameter for the respective device by a certain value; the processor configured by the instruction to generate the commands and control the transmission of the sequence of commands; wherein the processor controls a value in the memory of the increase or decrease instructed by the commands as a function of the time period needed to transmit one or more commands of the sequence of commands to each of the plurality of devices.
