Description

Code categorization method of composite remote control

As this is a public information case, the full text was not included.

3 is an output waveform diagram of the remote control signal receiving and amplifying unit 20 and the low pass filter 30 of the remote controller, and FIG. 4 is an enlarged view of a and b of FIG. 3 for the present invention.

Claims (4)

A method for categorizing and reproducing remote control information of a composite remote control, the method comprising: a first process of initializing, a second process of storing an input key, a third process of checking a mode switch, and the third process of input mode in the third process A fourth process of storing and inputting the data inputted in step 2 by category, and simultaneously displaying the data, and a fifth process of extending the code abbreviated to the output mode in the third process to transmit and display data pulses. Method characterized in that consisting of. The method of claim 1, wherein the fourth process comprises: a category flag checking process for checking a categorizable flag, and input remote control data information received for each period when the flag is set in the category flag checking process, the first input value and the first input value sequentially; The first modulation process of modulating to generate an index value as a reference for comparison with the next value when compared to the same value, and leaving only a sequence of values for the number of times in the column of values modulated in the first modulation process, And a second modulation process of removing and modulating the data width for each period to a reference value. The method of claim 1, further comprising: a key validity checking process of checking whether the fifth process is valid by receiving a key input, and extending the abbreviated code and outputting a pulse signal when the key is valid in the key validity checking process, and then performing the next key input. And a repetitive code generation process of generating a repetitive code when a key is input in the data pulse generation process. In the remote control signal processing method, the first step of storing the number of pulses input from the polling edge of the input data at an arbitrary address and the time according to the pulse generating portion, and the number of pulses and the pulse generating portion in the first step A second step of setting a maximum time after storing the time, a third step of storing the number of unit pulses inputted by checking whether there is a rising edge of the second step input data, and counting from the rising of the input data to the present time And a second step of storing the time and checking whether an arbitrary number has been input, and stopping the operation after setting a category-enabled flag when inputted in the first step. ※ Note: The disclosure is based on the initial application.
