Abstract: A method for determining the right code set to be used for controlling an appliance includes the remote control sends one or more commands using the corresponding code of at least one of the multiple code sets to the appliance. The code set to be used for controlling this appliance is determined based on at least a command sent to the appliance by a user of the remote control, in reaction to the sending of the one or more commands by the remote control.

Abstract: An apparatus, such as a database or a processor/memory combination of a remote control system, for supplying for example infrared codes defining functions for remotely controlling devices wherein code-sets include function-code-combinations for each one of two/more different functions. By distinguishing main-functions such as power on/off and sub-functions such as channel up/down and volume up/down, code-sets may be allocated to a group of code-sets for a target device in case a code of a function-code-combination for the main-function is valid for the target device. This increases an efficiency of the apparatus. The group of code-sets may form a tree, whereby the main-function and its code(s) form root of the tree, whereby a sub-function forms a branch of the tree and a code or cedes defining this sub-function form a leaf or leaves of the branch. The group of code-sets may be defined for device-types and/or device-brands.

Abstract: Universal Remote Controls are designed for controlling a large amount of appliances. Each of these appliances needs to be controlled by using codes of its own code set. For this reason, Universal Remote Controls store multiple code sets, so that they are able to control any of the appliances by using the corresponding code set. A method is described for determining the right code set to be used for controlling an appliance. Thereto, the remote control sends one or more commands using the corresponding code of at least one of the multiple code sets to the appliance (3040). The code set to be used for controlling this appliance is determined based on at least a command sent to the appliance by a user of the remote control, in reaction thereto (3070).

Abstract: In an apparatus (1), such as a database or a processor/memory combination of a remote control system (10), for supplying for example infrared codes defining functions for remotely controlling devices, code-sets comprise function-code-combinations for each one of two/more different functions. By distinguishing main-functions such as power on/off and sub-functions such as channel up/down and volume up/down, code-sets can be allocated to a group of code-sets for a target device in case a code of a function-code-combination for the main-function is valid for the target device. This increases an efficiency of the apparatus (1). The group of code-sets may form a tree, whereby the main-function and its code(s) form a root of the tree, whereby a sub-function forms a branch of the tree and a code or codes defining this sub-function form a leaf or leaves of the branch. The group of code-sets may be defined for device-types and/or device-brands.
