The centralized management of household appliances, especially the centralized management of home entertainment audio-visual equipment, is the core of the digital home system. At present, most home entertainment audio-visual devices are controlled by infrared remote controllers. In order to realize centralized management of these devices, it is necessary to learn the remote controllers of these devices.

However, learning many remote controllers will inevitably produce a large amount of remote controller learning data. If these learning data are not compressed, it will inevitably lead to the following problems: On the one hand, if these learning data are stored in the Flash or In other storage devices, it is necessary to provide a large enough storage space to store the learned remote control data, which increases the hardware cost of the product; on the other hand, the uncompressed remote control learning data is It will increase the transmission time and affect the user experience.

At present, there are mainly two methods for compressing remote control learning data: one is a compression algorithm based on RLE (Run Length Encoding); the other is a dictionary-based compression algorithm. The common feature of these two methods is that they continue to use the existing relatively mature compression algorithm, which can achieve the purpose of compression to a certain extent. However, these two methods have the following shortcomings: 1. They are not designed according to the unique characteristics of the remote control encoded data. The compression method leads to low compression rate and compression efficiency; 2. The implementation process of the compression method is relatively cumbersome, resulting in a relatively long time for parsing the data when sending infrared data for remote control of the device, which affects the user experience.

detailed description

The present invention provides a method and system for compressing learning data of a remote control, and a remote control. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Please refer to Fig. 1. Fig. 1 is a flow chart of a preferred embodiment of a method for compressing learning data of a remote control according to the present invention. As shown in the figure, it includes steps:

S101. Extract the common data bit from the remote control learning data, and construct the remote control coding template of the remote control through the data and position of the common data bit, where the common data bit refers to the numerical value in the learning data of each button within the error range all consistent data bits;

S102. Use the data bits other than the common data bits as non-common data bits, extract the data and positions of the non-common data bits of each key as key coded data, store them, and delete the original data at the same time;

S103. When it is necessary to control the device through a key of the remote control, extract the key code data of the key of the remote control, and merge it with the remote control code template to construct the complete infrared code data of the key of the remote control.

The realization principle of this embodiment is: all types of remote control codes are not the same, but no matter what type of remote control, most of its remote control code data are the same, only some keys are used to distinguish various keys Only the data bits are different, that is to say, the coding of each button of all remote controllers can be divided into two parts: one part is the common data bits that are unchanged for each button, and these data bits form the remote control coding template of this type of remote control ; The other part is the private data bit related to each key, that is, the non-common data bit, and these data bits form the coded data of each key.

For example, Figure 2 shows the original data (remote control learning data) collected by 3 different keys in a remote control of the TCL TV series. The abscissa represents the data bit, and the ordinate represents the data on the data bit, marked The vertical line indicates that the data bits (12, 14, 16, 20, 22, 24, 36, 38, 40, 44, 46, and 48) at this position are non-common data bits, and the unmarked data bits are public data bits. The data on the non-common data bits are not the same, but the data on the common data bits have the same size within the allowable range of error. And the present invention is designed and proposed based on that the coded remote controllers all have the coded feature.

According to the characteristics of the coded data of the remote control, this embodiment extracts the common data bits and forms a remote control code template with the placeholders, and then extracts the non-common data bits related to each key to form the key code data. When it is necessary to send the control command of the key of the remote controller, the data of each key stored originally can be restored by merging the common data bit and the key code data according to the remote control code template. In this way, for each type of remote control, only one coding template of the remote control and the data bit data related to each button need to be stored, without requiring a large amount of storage space to store repetitive data, thereby improving the data compression rate and Improved compression efficiency.

As a more preferred embodiment of the present invention, as shown in Figure 3, the step S101 specifically includes:

S201. Comparing all the data of the same data bit of each button of the remote controller;

For example, the learning data of a certain type of remote control is:

Key 1: irKey1[N]={k ₁₁ ,k ₁₂ ,…,k _1N };

Key 2: irKey2[N]={k ₂₁ ,k ₂₂ ,…,k _2N };

…

Key M: irKeyM[N]={k _M1 ,k _M2 ,…,k _MN };

Wherein, M is the serial number of the keys of a certain type of remote control; N is the data length of the encoded data of each key.

Then compare the data on the same data bit of each button, for example, the data k ₁₁ on the first data bit of button 1, the data k ₂₁ on the first data bit of button 2,..., the first data bit of button M The data of k _M1 .

S202. Determine whether all data of the same data bit are consistent in size within the allowable range of error, if so, use the data bit as a common data bit, and use the average value of all data of the data bit as the value of the common data bit, if Otherwise, the data bit is regarded as a non-common data bit, and the value of the non-common data bit is marked as zero;

S203. Record the values of each data bit in sequence in the remote control code template.

Then record the numerical value of each data bit in the remote control coding template in turn. There are N values in the array of the remote control coding template, where the value of the common data bit is the average value of all the data on the same data bit of all keys, and the value of the non-common data bit is 0.

An application example is provided below to illustrate the construction process of the remote control coding template.

Take the above remote control learning data as an example:

Key 1: irKey1[N]={k ₁₁ ,k ₁₂ ,…,k _1N };

Key 2: irKey2[N]={k ₂₁ ,k ₂₂ ,…,k _2N };

…

Key M: irKeyM[N]={k _M1 ,k _M2 ,…,k _MN };

Wherein, M is the serial number of the keys of a certain type of remote control; N is the data length of the encoded data of each key.

Current key value: keyValue=0;

The average value of the data of each button on the same data bit: =0;

Key cycle variable: m;

Data bit loop variable: n=1;

Remote code template array: keyCodeT[N]={kt ₁ ,kt ₂ ,…,kt _N }.

As shown in Figure 4, the construction process application embodiment of the remote control coding template specifically includes steps:

S301, start;

S302, judging whether n is greater than N; if not, enter step S303, and then proceed to step S311;

S303, m=2, keyValue=k _1n , =k _1n ;

S304, judging whether m is greater than M; if not, enter step S305, and then proceed to step S308;

S305. Judgment Whether it is less than T; when yes, enter step S306, otherwise proceed to step S309; here is to judge the average value of all data on the nth data position of all buttons before the mth button and the first value of the mth button Whether the difference of the data k _mn on n data bits is less than the evaluation threshold T, if yes, it is considered to be consistent within the error range, otherwise it is considered to exceed the error range.

S306, keyValue=keyValue+k _mn ;

;

S307, m=m+1, and return to step S304;

S308, keyCodeT[n]= , and enter step S310;

S309, keyCodeT[n]=0, and enter step S310;

S310, n=n+1, and return to step S302;

S311, end.

where the average , if a data bit is a common data bit, then the final average value of the data bit It is the value stored in the public data bit, and the average value of the key before the certain data bit also provides a standard for judging whether the data of the next key is consistent in size.

For example, assuming that there are 3 buttons, this embodiment only exemplifies 4 data bits among them for the convenience of description. It is obvious that the number and value of data bits in the learning data may be different in actual situations, so this example does not No limitation is imposed on the present invention. Suppose the specific data is as follows:

Button 1[4]={10,50,10,80};

Key2[4]={9,51,8,78};

Key 3[4]={11,49,2,100};

Judge the second button:

keyValue = k ₁₁ = 10;

=k ₁₁ =10;

| -k ₂₁ |<5(T, evaluation threshold);

Then keyValue=keyValue+k ₂₁ =19;

=keyValue/2=9.5;

Judge the third button:

| -k ₃₁ |<5(evaluation threshold);

Then keyValue=keyValue+k ₃₁ =30;

=keyValue/3=10, so, finally =10, and this data bit is a public data bit.

Through the above example, the finally obtained array of remote control coding templates:

keyCodeT[N]={kt ₁ ,kt ₂ ,…,kt _N } is the remote control code template of this type of remote control to be constructed in the end. In the above embodiment, T is the evaluation threshold, which is used to judge whether the current mean value of the current data bit is consistent with the data of a certain button on the data bit within the allowable range of error, and the value of T can be determined according to the actual situation. . In this remote control coding template, N numerical values are recorded successively, for the public data position, its numerical value is the average value of all the data of each button on the public data position, and for the non-common data position, then the numerical value is marked as zero, In order to use in the subsequent extraction of key code data.

As a more preferred embodiment of the present invention, as shown in FIG. 5, the step S102 specifically includes:

S401. Record the position of the non-common data bit whose numerical value is marked as zero in the remote control coding template;

Here is to judge which data bits belong to public data bits and which belong to non-common data bits according to whether each value in the remote control coding template is zero. The data of each button on the same data bit is extracted.

S402. According to the positions of the non-common data bits, sequentially extract the data on the non-common data bits of each key from the learning data of the remote control, and construct key code data.

The data extracted from the non-common data bits are the private data related to each button. These data will be completely extracted to construct the data related to each button code, and then the remote control learning data can be deleted, because from the remote control code The remote controller learning data can be restored from the template and key code data, so the original remote controller learning data can be deleted, because a large amount of repetitive data, that is, the data on the common data bit, is eliminated, so the present invention greatly improves the compression rate and compression efficiency.

A specific embodiment is provided below to illustrate the construction of key code data.

Button cycle variable: m=1;

Data bit loop variable: n=1;

Key coded data array loop variable: s=1;

Remote code template array: keyCodeT[N]={kt ₁ ,kt ₂ ,…,kt _N };

Key code data array: keyCodeP[M][S]; among them, M is the number of keys, S is the number of non-common data bits, for example, the non-common data of key 1 is keyCodeP[1][S], and that of key 2 The non-public data is keyCodeP[2][S]..., and so on. And s is a variable for counting non-common data bits.

As shown in Figure 6, it specifically includes steps:

S501, start;

S502, judging whether n is greater than N; if not, enter step S503, and then proceed to step S510;

S503, judging whether keyCodeT[n] is equal to zero; if yes, enter step S504, otherwise proceed to step S509;

S504, m=1;

S505, judging whether m is greater than M; if not, enter step S506, and then proceed to step S508;

S506, keyCodeP[m][s]=k _mn ;

S507, m=m+1, then return to step S505;

S508, s=s+1;

S509, n=n+1, then return to step S502;

S510, end.

The obtained keyCodeP[m][s] form the final array keyCodeP[M][S], which is all extracted key code data.

As a more preferred embodiment of the present invention, the step S103 specifically includes:

Determine whether the value of each data bit in the remote control code template is zero in turn, when not, extract the value of the corresponding data position in the remote control code template, when it is, extract the data on the corresponding data position of the key in the key code data, and extract The resulting data are merged.

In this embodiment, it is first judged whether the value of each data bit in the remote control coding template is zero, if it is zero, then it means that the corresponding data bit is a non-common data bit, if it is not zero, then it means that the corresponding data bit is a public data bit . Different processing is performed for data bits of different properties. For the public data bit, you need to extract the value on the public data bit from the remote control code template (each key is the same), and for the non-public data bit, you need to extract the key on the data bit from the key code data In this way, the complete infrared coded data of the button is formed, and the control of the smart device by sending button commands is realized.

A specific embodiment is provided below to specifically illustrate the process of decompression and restoration.

The serial number of the button command to be sent: m;

Data bit loop variable: n=1;

Key coded data array loop variable: s=1;

Array of remote control code templates: keyCodeT[n];

Key code data array: keyCodeP[M][S];

Remote control code data array: keyCode[N]=keyCodeT[N];

As shown in Figure 7, it specifically includes steps:

S601, start;

S602, judging whether n is greater than N; if not, proceed to step S603, and if yes, proceed to step S607;

S603, judging whether keyCodeT[n] is equal to zero; if yes, enter step S604, and when no, proceed to step S606;

S604, keyCode[n]=keyCodeP[m][s]; for the case of keyCodeT[n]=0, it means that the data bit is a non-public data bit, so it is necessary to obtain the data of the corresponding data bit from the key code data array , and record to the remote control code data. For the case where keyCodeT[n] is not equal to 0, the value in the remote control code template can be recorded in the remote control code data according to the method of keyCode[N]=keyCodeT[N], and the operation is repeated in turn to obtain the value of each data bit. The data thus constitutes the remote coded data, that is, the complete infrared coded data.

S605, s=s+1;

S606, n=n+1, then return to step S602;

S607, end.

The obtained array keyCode[N] composed of each keyCode[n] is the restored complete infrared coded data of the key.
