Embodiment 1

[0089] Based on the above specific examples, the method for learning the infrared coded signal of the remote controller provided by Embodiment 1 of the present invention is as follows: figure 2 shown, including the following steps:

[0090] Step 200, respectively recording the level width values ​​of at least two pilot codes sequentially received before the infrared coding control signal;

[0091] The high and low levels of at least two pilot codes appear alternately, wherein the first pilot code is high level, and the last pilot code is low level. If there is no pilot signal, this step can be omitted.

[0092] Step 201, receiving the infrared coded control signal sent by the remote controller to be learned, obtaining the carrier period of the infrared coded control signal, and the sequence of occurrence of high level and low level in the infrared coded control signal and the level width value, wherein the infrared coded control signal The first time in the middle is a high ...

Embodiment 2

[0123] In order to further save the amount of encoded data, it is also possible to establish a correspondence table between level width value encoded data and indexes as shown in Table 3 below for a learned remote controller:

[0124] table 3.

[0125] level width value index

Level Width Value Encoded Data

[0126] 001

Level width value encoded data 1

010

Level width value encoded data 2

011

Level width value encoded data 3

100

Level width value encoded data 4

101

Level width value encoded data 5

……

……

[0127] In the corresponding relationship table, the encoded data and index of the level width value are uniformly stored, and there is no need to store the level width code data string in the encoded data of each infrared encoded signal. The number of bits occupied by the index value in the corresponding relationship table is based on experience The value is determined, as lo...

Embodiment 3

[0168] When it is necessary to learn the infrared coded signals of different remote controllers of multiple devices, in order to further save the amount of coded data, you can also establish the correspondence table between the level width value coded data and the index as shown in Table 4 below:

[0169] Table 4.

[0170]

[0171] Wherein, the level width value index includes a group number and a serial number, the group number represents the level width value learned for the first time in an infrared coded signal, and the number identifies the sequence in which the level width values ​​are learned in the infrared coded signal. Specifically, the group number of the level width values ​​learned in the first infrared coded signal is 00, and the sequence numbers of all four learned level width values ​​are 00, 01, 10, and 11. Subsequent to the different level width values ​​​​learned in other infrared coded signals, the group numbers are sequentially compiled. For example, 6 ...

Abstract

The invention relates to a remote control technology, in particular to an infrared code signal learning technology in the remote control technology, and the invention discloses a learning method and a transmitting method of the infrared cod signal of a remote controller and the remote controller, which are used for realizing the learning and the reduction of the infrared code signal of the remote controller and reducing the code data volume as much as possible so as to save the storage space. According to the learning technology of the infrared code signal, which is provided by the embodiment of the invention, indexes can be established for different level widths and can be coded and stored according to the sort orders of high and low levels; the width and the order of the levels can be sequentially determined according to the coding and the sort order of the indexes, thereby the code data volume can be greatly saved and the storage space of the remote controller can be saved when the infrared code signal appears repeatedly at the same level width.

Description

technical field [0001] The invention relates to remote control technology, in particular to an infrared coded signal learning technology in the remote control technology. Background technique [0002] With the improvement of living standards, the types of electrical appliances in general households are becoming more and more abundant. The increase in the types of home appliances brings a wide variety of remote controls. For example, commonly used ones include: TV remote controls, DVD player remote controls, room air conditioner remote controls, and power amplifier remote controls in home theaters. A wide variety of remote controllers brings inconvenience to use and storage, and the demand for remote controllers that can control multiple types of home appliances arises as the times require. [0003] And the universal remote control on the existing market is designed for a certain type of electrical equipment, and generally can control the same type of home appliances of diff...
