and using it for sending the user commands, power saving is
achieved with respect to the prior art solution of sequentially
sending a plurality of codes corresponding to a command.
According to an embodiment, the remote control during
normal operation automatically sends a fake command (i.e. a

BACKGROUND OF THE INVENTION
In this case, the user will not react and it can be determined

that (one of) the sent code(s) corresponds to the code set used
ances needs to be controlled by using codes of its own code set
corresponding to a certain Infra Red (IR) protocol. There are
20
basically two known solutions for dealing with this issue.
According to the ?rst known solution, when the user
selects a certain command (i.e. a function, such as power
on/off, volume up/down, etc.) on the remote control, the
codes corresponding to this command from a prede?ned sub

set of all code sets of the URC (the most common code sets)
are sequentially sent. The main disadvantage of sending
Preferably, the fake command is intermittently sent, each
codes sequentially is that a user has to wait until all codes are
sent, before he can issue a new command. Another drawback
is that so called repetition features of the applicable IR pro
tocol cannot be used. As a result, the appliance will react
noticeably slower to some commands than when it is used
with its original (proprietary) remote control. In case of
audiovisual appliances, an example of such a command
resulting in a slow reaction is “Volume up/ down”. This com
by the appliance, its state will change, accordingly. Generally,
the user will undo this fake command by selecting an appro
priate command on the remote control within a certain time
limit. In case that the user, in reaction to the fake command,
sends such a command undoing the fake command, it is
determined that the appliance probably uses the code set,
from which (one of) the code (s) was taken to send the fake
command.

time by using a code from a single code set. The used code set
is varied over time until all of them have been tried. In this
way, the used code set can be determined with a high prob
ability in a reasonable time.
According to a further embodiment, a command selected
by the user is sent to the appliance using the corresponding

command is sent using codes from a subset of code sets not

corresponding to the appliance, the state of the appliance does

command within a time interval. So, such a repeated sending
sequentially, more codes are sent than needed wasting bat

a certain appliance by selecting the corresponding code set in
a special set up mode. WO 2007/ 105142 discloses several
methods for this purpose. However, these methods need user
command within a certain time interval, this is probably
because the state of the appliance has changed as expected by
45
con?rmation if the selected code set works properly with the
appliance. Thereto, the user must follow certain user instruc
tions. Such instructions may be provided to the user by means

Some user groups, for example young children or elderly
people are not able to carry out such instructions and for the
remaining user groups it is a burden.
SUMMARY OF THE INVENTION
It would be advantageous to enable the determination of a
code set to be used out of multiple code sets in a remote
control in a more user-friendly way.
To better address this concern, in a ?rst aspect of the inven
tion a method is provided for determining a code set to be used
out of multiple code sets in a remote control for controlling an
55
60
reaction thereto.
According to a still further embodiment, a command
selected by a user is sent using the corresponding code of at
least one of the multiple code sets a different number of times
than the corresponding code of at least another one of the
multiple code sets. Preferably, the command is taken out of
the group of commands having an opposite command, the use
of the opposite command resulting in an opposite effect at the
appliance to the effect caused by the command. The code set
to be used may then be determined based on the proportion of
the number of times that the command and the opposite
command are selected by the user during a time interval. For
example, in case that the appliance works with a code set of
which the command is sent by repeating the corresponding
code several times (i.e. a plurality of frames is sent) and the
opposite command is sent by sending the corresponding code

controlled to send these codes to the appliance. If codes from
the right code set are sent to the appliance, the appliance will
change its state. Otherwise the state of the appliance will most
likely not change. Thereafter, the commands, which the user
sends to the appliance in reaction to the transmitted com
mands, are analyzed 3050. It is then determined if further tests
are needed to determine the right code set for the appliance

a certain time interval (for example a few seconds), it is very

with only a single code set (IR protocol). So, the URC must
select the right code set to be used for controlling the appli
ance.
FIG. 1 schematically shows the relationship between the
set of commands 100 of a remote control and a plurality of
code sets (IR protocols) 200, 300, . . . 900. The set 100 of
commands consists of a plurality of commands 101,102, . . .
According to a further embodiment of the present inven
tion, when a user during normal operation selects a command,
the corresponding codes of only a subset of all code sets
stored in the memory 2040 are sequentially transmitted (step
3040). For example, in case that the user presses “power off”
for controlling a TV-set, only the corresponding codes from

the code sets of only a subset of all manufacturers are sent. If
the user presses “power off” again within a few seconds, it is
likely that his TV-set is not of any of these manufacturers.

Repeating this test a number of times with different subsets,
will ultimately lead to the determination of the right code set
take out the batteries and put them back in. So if the user takes
out the batteries, for example, the last two discarded codesets
may be “readmitted” to the testing algorithm and all other
(step 3070).
According to a still further embodiment, during normal
code sets may be discarded.
Additionally, user pro?les may be used to optimize the
operation a command selected by a user is sent using the
corresponding code of at least one of the multiple code sets a
different number of times than the corresponding code of at
least another one of the multiple code sets. The command may
be taken out of the group of commands having an opposite
command. The code set to be used may then be determined
based on the proportion of the number of times that the
command and the opposite command are selected by the user
algorithm for determining the right code set. For example, it
may be determined from the commands that are selected by
the user, if he is a “zapper”, i.e. he uses only channel up/ down
to change channels or a “non-zapper”, i.e. he uses the digit
buttons on his remote control for channel selection. A further
example hereof is to check whether the user uses the mute
button or uses the volume down button to mute. Such infor
during a time interval. An example hereof is asymmetric
volume control. For example, for the command “volume up”
mation may be used to speed up the search for the right code
the corresponding code of a TV-set of a ?rst manufacturer is
sent twice (in other words, two frames with the code corre
mute, the algorithm using asymmetric volume control
sponding to the “volume up” command are sent) and the
corresponding code for TV-sets of all other manufacturers is
more ef?cient to use an algorithm for determining the right
code set, which uses different commands.
Based on the user behavior during normal operation as
described so far, conclusions may be drawn that are useful if
the user subsequently selects a set-up mode for selecting the
sent once. For the opposite command “volume down” the
corresponding code of a TV-set of a second manufacturer is
sent twice and the corresponding code for TV-sets of all other
manufacturers is sent once. After tracking the commands
generated by the user for some time, the proportion of the
number of times that “volume up” and “volume down” are
pressed is checked (step 3050). If the user presses “volume
down” two times more than “volume up”, he is probably
using the TV-set of the ?rst manufacturer. If the user presses
“volume up” two times more than “volume down”, he is
probably using the TV-set of the second manufacturer. If he
presses “volume up” and “volume down” roughly the same
amount of times, he is probably using a TV-set of neither the
?rst nor the second manufacturer. If it is likely that a TV-set of
either the ?rst or the second manufacturer is used, it may be
determined that extra tests have to be performed (step 3060),
for example by sending three codes per command in one
direction and one code per command in the other direction. If
it is likely that a TV-set of neither the ?rst nor the second
manufacturer is used, the test can be repeated by sending two
codes per “volume up” command for a third manufacturer and
two codes per “volume down” command for a fourth manu
facturer.
The different embodiments described herein above may be
applied alone or in combination.
It would be advantageous to use metadata of the code sets
in order to determine the right code set. For example, for a
Samsung® TV-set, the user needs to press the command
“-/--” to enter double digit numbers, for a Philips® TV-set that
is not needed. Philips® TV sets switch on when the power
button is pressed, LG® TV sets do not. On a Philips® TV-set

for red on the red button and one with the Ircode for smart
sound on the red button. As a result, it may occur that all
45
commands work ?ne, except the red, green, yellow and blue
buttons. In this case it is not needed to go through the full
setup starting from the start, but the processor can leverage on
what is already known from the users behaviour. In short,
information is captured in order to ?nd the right codeset in a
selected subset of code sets (in this example, the subset of
code sets for Philips® TV sets). If the right codeset is not
found in the subset, the captured information can still be used
to ?nd the right codeset in the complete set of available code
sets.
