DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] Please refer to Figure 1 , Figure 1 The flowchart of a data communication method applied to a universal remote controller provided in an embodiment of the present application is shown in FIG. The universal remote controller in an embodiment of the present application is connected to a set-top box and a controlled device, and the controlled device is a television or other device that communicates with the set-top box. Figure 1 As shown, the data communication method applied to the universal remote controller of this embodiment includes steps S101 to S104, which are described in detail as follows: Step S101, sending a Bluetooth key value to the set-top box to obtain an infrared waveform code value returned by the set-top box.

[0018] In this step, the set-top box stores the infrared waveform code value of the controlled device. Taking a television as an example, the controlled device is a set of infrared waveform code values ​​of the television set a. The universal remote control is connected to the set-top box A via Bluetooth, and sends a Bluetooth key value to the set-top box A to obtain the infrared waveform code value returned by the set-top box A according to the Bluetooth key value, thereby performing infrared communication with the television set a according to the infrared waveform code value; when the universal remote control controls the television set b, the universal remote control obtains a set of infrared waveform code values ​​of the television set b stored by the set-top box B. It can be seen that the universal remote control does not need to store multiple infrared protocol code values, but only needs to have enough storage capacity to store a set of infrared waveform code values. The set-top box as a receiving end only needs to store a set of infrared waveform code values ​​of the television set it controls, thereby greatly reducing the storage capacity requirements of the remote control and the receiving end.

[0019] Step S102, using a preset infrared compression algorithm to extract waveform data features of the infrared waveform code value, the waveform data features include waveform data number, waveform data dictionary, data code waveform number, data code waveform description, data repetition description bit and repetition code waveform description.

[0020] In this embodiment, the waveform data dictionary is used to characterize the types of waveform values ​​used in the infrared waveform code value, the number of waveform data is used to characterize the number of waveform value types recorded in the waveform data dictionary, the data code waveform description is used to characterize the data code waveform after the infrared waveform code value is compressed, the repetition code waveform description is used to characterize the repetition code waveform after the infrared waveform code value is compressed, the number of data code waveforms is used to characterize the length of the data code waveform and whether it is repeated, and the data repetition description bit is used to characterize the length of the repetition code waveform and whether it is repeated. This embodiment extracts features from the infrared waveform code value by using a preset infrared compression algorithm, so that data compression and data encryption can be performed during feature extraction, thereby reducing the amount of data and improving data security.

[0021] Step S103, combining the waveform data features to obtain a target infrared waveform code value.

[0022] In this step, the number of waveform data, the waveform data dictionary, the number of data code waveforms, the data code waveform description, the data repetition description bit and the repetition code waveform description are sequentially spliced ​​to obtain the target infrared waveform code value.

[0023] Step S104: sending the target infrared waveform code value to the controlled device.

[0024] In this step, the universal remote controller sends the compressed infrared waveform code value to the controlled device, and the controlled device parses the target infrared waveform code value to perform a corresponding operation.

[0025] In some embodiments, Figure 2 As shown, the step 102 includes steps S1021 to S1025, which are described in detail as follows: Step S1021 , extracting a waveform data dictionary of the infrared waveform code value based on the waveform value of the infrared waveform code value.

[0026] In this step, the waveform data dictionary is extracted to extract all waveform values ​​used by the infrared waveform code value, so as to facilitate further feature extraction of the infrared waveform code value by other data features.

[0027] Optionally, from all waveform values ​​of the infrared waveform code value, two first waveform values ​​whose byte number is the first preset byte number and whose usage frequency is the highest are screened out as the front part of the waveform data dictionary; the second waveform value whose byte number is the first preset byte number and whose usage frequency is after the first waveform value is used as the middle part of the waveform data dictionary; and the third waveform value whose byte number is the second preset byte number is used as the back part of the waveform data dictionary.

[0028] In this optional embodiment, the preset infrared compression algorithm for the waveform data dictionary is: fill in all waveform values ​​to be used for the infrared waveform code value; place the waveform value with the highest frequency of use and 2Bytes in the first two digits of the waveform data dictionary, represented by 2bits (00 / 01), and other dictionaries are represented by 4bits, with the highest bit marking position 1, 0B10, 0B11 and 0B1111 are all invalid dictionary identifiers.

[0029] For example, taking the NEC waveform value uPD6121G (hereinafter referred to as sample data) as an example, its waveform data is as follows: 9000,4500,560,1680,560,560,560,560,560,560,560,560,560,560,1680,560,560,560,560,560,560,560,560,1680,560,560,560,560,1680,560,1680,560,1680,560,560,1680,560,1680,560,560,1680,560,560,1680,560,5 60,560,560,1680,560,1680,560,560,560,560,560,560,560,560,560,560,560,560,560,560,1680,560,560,560,560,560,1680,560,560,1680,560,1680,560,40180,9000,2250,560,96190.

[0030] Place the two 2-Byte waveform values ​​with the highest frequency (560, 1680) at the front, followed by other 2-Byte waveform values ​​(2250, 4500, 9000, 40180), and finally the 3-Byte waveform value (96190). The waveform data dictionary is: 560, 1680, 2250, 4500, 9000, 40180, 96190.

[0031] Step S1022: counting the number of waveform data of the infrared waveform code value based on the waveform data dictionary in accordance with a first preset data format.

[0032] In this step, since the waveform length of some waveform values ​​is greater than 65535 and requires 3Bytes to support the waveform length, the waveform values ​​are classified into 2Bytes waveform type (bit0-bit3: 0-9) and 3Bytes (bit4-bit7: 0-7) waveform type, and the total number of the two types of waveform types does not exceed 9. The first preset data format is as follows Figure 3 As shown, it includes reserved bits, the number of 2-Bytes waveform values, and the number of 3-Bytes waveform values.

[0033] Optionally, based on the waveform length of the waveform values ​​in the waveform data dictionary, the waveform data dictionary is classified to obtain multiple waveform types; the number of waveform values ​​corresponding to each waveform type in the waveform data dictionary is counted; and according to the first preset data format, the number of waveform values ​​is generated as the number of waveform data.

[0034] In this optional embodiment, taking the above sample data as an example, the waveform data dictionary (560, 1680, 2250, 4500, 9000, 40180, 96190) is classified according to the waveform length of the waveform value, wherein 560, 1680, 2250, 4500, 9000, 40180 are all less than 65535, so they are classified as 2Bytes waveform type, a total of 6 2Bytes waveform types, that is, bit0-bit3 is 6 (binary number is 0b0110); 96190 is greater than 65535, so it is classified as 3Bytes waveform type, a total of 1 3Bytes waveform type, that is, bit4-bit6 is 1 (binary number is 0b0001), and the preset bit is 0. Therefore, according to the first preset data format, the number of waveform data is 22 (0d00010110).

[0035] Step S1023, in accordance with a second preset data format, based on the waveform data dictionary and the number of bits and the continuity relationship of the waveform value, the infrared waveform code value is waveform described to obtain a data code waveform description and a repetition code waveform description of the infrared waveform code value.

[0036] In this step, each 2-bit dictionary occupies two bits of space, and each 3-bit dictionary will take up four bits of space with the header "1"; when the 2-bit dictionary is used continuously, no bit padding is required; when the 2-bit dictionary is used discontinuously, a 0B11 low-bit padding operation is required; when the 3-bit dictionary is placed at the low address of the end byte as the end bit, a 0B1111 bit padding operation is required. The second preset data format is as follows Figure 4 As shown, waveform descriptions corresponding to different bit numbers and continuous relationships are included.

[0037] Optionally, according to the second preset data format, based on the waveform data dictionary and the number of bits of the waveform value, the binary number of each waveform value in the infrared waveform code value is determined; based on the continuous relationship between the waveform data, the continuous binary numbers are spliced ​​to obtain multiple binary codes, and the continuous relationship is the continuous relationship preset in the second preset data format; each of the binary codes is converted to obtain a data code waveform description and a repetition code waveform description.

[0038] In this optional embodiment, taking the above sample data as an example, the first 12 bytes of the sample data are: 9000, 4500, 560, 1680, 560, 560. According to the waveform data dictionary and the second preset data format, 9000 is 0b1010, 4500 is 0b1001, 560 is 0b00, and 1680 is 0b01. Therefore, in combination with the second preset data format, 9000 and 4500 are 3 bits continuous. Bytes0 is 154 (binary number is 0b1001-1010), 560, 1680, 560, 560 are 2 bits continuous, then Bytes0 is 4 (binary number is 0b00-00-01-00), and so on. The complete data code waveform of the above sample data is described as: 154, 4, 0, 64, 0, 64, 68, 4, 68, 4, 68, 0, 0, 64, 0, 68, 68, 179.

[0039] The last 9 bytes of the above sample data are the waveform values ​​of the repetition code 9000, 2250, 560, 96190. Similarly, the waveform description of the repetition code is 138, 195.

[0040] Step S1024: generating the number of data code waveforms of the infrared waveform code value according to a third preset data format based on the data code waveform description and a preset data protocol.

[0041] In this step, the third preset data format is as follows Figure 5 As shown, the number of bytes occupied by the data code waveform (bit0-bit5: 0-63Bytes); data code repeat enable bit (bit6): if this bit is 1, the data repetition description bit data code repetition count bit field is valid; if this bit is 0, the data repetition description bit data code repetition count bit field is invalid; repeat code enable flag bit (bit7): if this bit is 1, the data repetition description bit repeated waveform occupied byte number bit field is valid, and there is a repeated code waveform description segment; if this bit is 0, the data repetition description bit repeated waveform occupied byte number bit field is invalid, and there is no repeated code waveform description segment; if the above two bits are both 0, there is no data repetition description bit.

[0042] Optionally, determine the number of bytes corresponding to the data code waveform description; based on the data code waveform description, determine the data code repetition state of the infrared waveform code value; based on the preset data protocol, determine the repetition code state of the infrared waveform code value; and according to the third preset data format, perform data conversion on the number of bytes of the data code waveform description, the data code repetition state and the repetition code state to obtain the number of data code waveforms.

[0043] In this optional embodiment, taking the above-mentioned sample data as an example, according to the complete data code waveform description of the sample data, the data code waveform occupies 18 bytes, that is, bit0-bit5 is 18 (binary number is 0b010010), and according to the preset data protocol, if the data code in the sample data is not repeated, then bit6 is 0, and if there is a repeated code in the sample data, then bit7 is 1, so the number of data code waveforms is 146 (binary number is 0b10010010).

[0044] Step S1025: generating data repetition description bits of the infrared waveform code value based on the repetition code waveform description in accordance with a fourth preset data format.

[0045] In this step, the fourth preset data format is as follows Figure 6 As shown, data repetition times (3 bits): defines the number of times the data code waveform is repeated, with a minimum of 0 times and a maximum of 7 times; number of bytes occupied by the repeated code waveform (3 bits): the number of bytes occupied by the repeated code waveform, with a maximum of 7 bytes.

[0046] Optionally, based on the repetition code waveform description, the number of bytes corresponding to the repetition code waveform description and the data code repetition status of the infrared waveform code value are determined; according to the fourth preset data format, the number of bytes of the repetition code waveform description and the data code repetition status are converted to obtain the data repetition description bit.

[0047] In this optional embodiment, taking the above-mentioned sample data as an example, according to the repetition code waveform description of the sample data, the number of bytes occupied by the repetition code waveform is 2, that is, bit0-bit2 is 0b010, and the data code is not repeated, that is, bit3-bit5 is 0, and the reserved bit is 0, then the data repetition description bit is 2 (the binary number is 0b00000010).

[0048] For example, using Figure 7 The data format shown combines the data features to obtain the target infrared waveform code value: 22,560,1680,2250,4500,9000,40180,96190,146,154,4,0,64,0,64,68,4,68,4,68,0,0,64,0,68,68,179,2,138,195.

[0049] Obviously, compared with the sample data before compression (72Bytes), the compressed sample data (38Bytes) can greatly reduce the data volume of the infrared waveform code value.

[0050] As an example but not a limitation, take the waveform value M50560 as an example, before compression (114Bytes): 8500,4250,530,530,530,530,530,1590,530,530,530,1590,530,530,530,530,530,530,530,530,4250,530,1590,530,1590,530,1590,530,1590,530,1590,530 ,1590,530,530,530,530,530,530,530,17560,8500,4250,530,530,530,530,530,1590,530,530,530,1590,530,530,530,530,530,530,530,530,4250 ,530,1590,530,1590,530,1590,530,1590,530,1590,530,530,530,530,530,530,530,530,17560,8500,4250,530,530,530,530,530,530,1590,530,530,530 30,1590,530,530,530,530,530,530,530,4250,530,1590,530,1590,530,1590,530,1590,530,1590,530,530,530,530,530,530,530,530,17560,60000 After compression (24Bytes): As an example but not a limitation, take the waveform value DVB / Pan 7051 / SAMSUNG as an example, before compression (200Bytes): 3640,1800,380,380,380,1350,380,380,380,380,1350,380,380,380,380,380,1350,380,380,380,380,1350,380,380,380,1350,380,380,380,380,1350,380,380,380,380,1350,380,380,380,380,1 350,380,380,380,380,380,135 ... 0,380,380,380,380,1350,380,380,380,1350,380,380,380,1350,380,380,1350,380,380,380,1350,380,380,380,1350,380,380,380,380,1350,380,380,380,50000,3640,1800,380,380,380,1 350,380,380,380,1350,380,380,380,380,380,1350,380,380,380,380,1350,380,380,380,380,1350,380,380,380,380,380,1350,380,380,380,380,380,1350,380,380,380,380,380,380,1350,380,380,380,380,380,380 ,1350,380,1350,380,1350,380,1350,380,380,380,380,380,380,380,380,380,380,380,1350,380,1350,380,1350,380,1350,380,380,380,380,380,380,380,380,380,380,380,380,380,380,380,380 0,380,380,380,380,1350,380,380,380,1350,380,380,380,1350,380,380,1350,380,380,380,1350,380,380,380,1350,380,380,380,380,1350,380,380,380,50000.
