Refer to Fig. 1, Fig. 1 is the flow chart of the compression method preferred embodiment of a kind of remote controller learning data of the present invention, and as shown in the figure, it comprises step:
S101, from remote controller learning data, extract public data position, by the data of public data position and the remote control coding template of position structure remote controller, public data position described here refers to the data bit that in each button learning data, numerical values recited is consistent in error range;
S102, using the data bit outside public data position as unshared data bit, the data of the unshared data bit of each button and position are extracted as keyboard-coding data, and store, delete initial data simultaneously;
S103, when needing the button control appliance by remote controller, the keyboard-coding data of this this button of remote controller to be extracted, and merge with described remote control coding template, construct the complete infrared coded data of this button of this remote controller.
The principle that realizes of the present embodiment is: all types of remote controller codes is all not quite similar, but be no matter the remote controller of which kind of type, its remote control coding data major part is all identical, only have some just distinct for the data bit distinguishing assortment of keys, that is, the coding of all each buttons of remote controller can be divided into two parts: a part is the public data position that each button is constant, and these data bit form the remote control coding template of the type remote controller; Another part is the private data position relevant to each button and unshared data bit, and these data bit form the coded data of each button.
Citing is described, the initial data (remote controller learning data) that Fig. 2 collects for 3 different keys in TCL television series one remote controller, abscissa representative data position, ordinate represents the data in this data bit, marking the data bit (12,14,16,20,22,24,36,38,40,44,46 and 48) that vertical line represents on this position in figure is unshared data bit, no the data bit of mark is not public data position, data in unshared data bit are not quite similar, and the data on public data position then size are in the same size in error allowed band.And the present invention has this coding characteristic based on coded telecommand device just and design proposition.
According to the feature of remote controller codes data, public data position extracts and forms remote control coding template with placeholder by the present embodiment, then by with the relevant unshared data bit extraction of each button out, forms keyboard-coding data.When needing the control command of the button sending this remote controller, according to remote control coding template, public data position and keyboard-coding data are merged the data that just can be reduced to original each button stored.Like this for the remote controller of each type, only need store the data bits certificate that the coding templet of a remote controller is relevant with each button, and do not need a large amount of memory spaces to store the data of repeatability, thus improve data compression rate and improve compression efficiency.
As the preferred embodiment of the present invention, as shown in Figure 3, described step S101 specifically comprises:
S201, all data of the same data bit of each button of remote controller to be compared;
Such as certain type remote controller learning data is:

Button 2:irKey2 [N]={ k 21, k 22..., k 2N;
Button M:irKeyM [N]={ k m1, k m2..., k mN;
Wherein, M is the button sequence number of certain type remote controller; N is the data length of each keyboard-coding data.
Then the data in the same data bit of each button are contrasted, such as, data k in the first data bit of button 1 11, the data k in the first data bit of button 2 21..., the data k in first data bit of button M m1.
S202, judge that whether all data of same data bit are all in the same size in error allowed band, if then using this data bit as public data position, and using the numerical value of the mean value of all data of this data bit as this public data position, if not then using this data bit as unshared data bit, the numerical value with the unshared data bit of tense marker is zero;
S203, the numerical value of each data bit to be recorded in remote control coding template successively.
Again successively by the records of values of each data bit in remote control coding template.In the array of this remote control coding template, have N number of numerical value, the numerical value of public data position is wherein the mean value of all data in the same data bit of all buttons, and the numerical value of unshared data bit is 0.

2nd button is judged:
keyValue=k 11=10;
=k 11=10;
| -k 21| <5 (T, Evaluation threshold);
So keyValue=keyValue+k 21=19;
=keyValue/2=9.5;
3rd button is judged:
| -k 31| <5 (Evaluation threshold);
