The present invention relates to a key function memory method of a remote controller, which allows a key of a remote controller to arbitrarily program a function desired by a user and to check key functions in a current state, thereby simplifying key arrangement and simplifying use.

Recently, as the functions of electronic products are diversified, the number of function keys of the remote control increases, and the function names are complicated, causing confusion among users when using the remote control.

Therefore, in order to prevent this, the general remote control included with each product is supplied with two kinds of a full-function remote control having all the function keys and a simple function remote control having only the keys commonly used, or It provides a function and gives a simple function to the rear part, or a function to cover the lid for functions other than the simple function so as not to be noticed in normal use. However, this method is difficult to use as the number of keys increases in the case of the full-function remote control, causing user confusion, and the volume of the remote control increases, but there is a problem that increases the number of unused keys. In fact, there is a problem in that it is difficult to arrange a key to satisfy this, because there is a difference in the key commonly used by consumers according to the hierarchy, there was a problem that you need to use two types of remote control.

In the case of the universal remote control commonly used in various products, the number and function names of the function keys are different according to each product, so it is difficult to accommodate all of them. A method of setting a double execution key to perform a function by pressing two or more keys and describing the contents in the manual has been adopted.

However, this method has many more keys than necessary when recording all the keys according to the type of the product, causing inconvenience and confusion. When two or more keys are used together, they are limited to simple function keys. There was a problem that can not record all the functions, and even if programmable, there is a problem that can be used without the existing remote control because it stores the data value of the existing remote control to 1: 1.

Accordingly, it is an object of the present invention to provide a key function memory method of a remote controller which enables the user to perform the maximum function while having the minimum number of keys by storing the remote control code having a desired function in an arbitrary key.

It is another object of the present invention to provide a key function memory method of a remote controller that enables the user to check the current key function during the key program for convenience of use.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an internal block diagram of a remote controller to which the present invention is applied, and FIG. 2 is a detailed circuit diagram of the remote controller. The microcomputer 10 controls the overall operation of the remote controller as shown in FIG. The battery unit 20 to be supplied, the reset unit 30 which checks the power state and resets the microcomputer 10, the numeric keys, the memory keys, the general function keys, and the like are configured in a matrix form. A key matrix unit 40 for inputting an operation command to the controller, a clock generation unit 50 for supplying a clock signal to the microcomputer 10 for synchronization, an external ROM 60 storing a remote control code format, Carries a display unit 70 comprising resistors R1, capacitors C1, C2, and light emitting diodes LED1, which display the operation state under the control of the microcomputer 10, and a data code output from the microcomputer 10. A transistor TR1, a resistor R2, which is loaded on a carrier and sent out in an infrared signal form, It consists of infrared LED (LED2), the infrared transmission section 80 to the (LED3).

Here, the microcomputer 10 stores a mode setting unit 10A for receiving a key signal from the key matrix unit 40 to set a mode, a program to be executed in the microcomputer 10, or data being processed and stored therein. The internal memory 10B for outputting the data, the clock signal from the clock generator 50, the data processing unit 10C for receiving data from the storage device and performing calculation and control, and the control of the data processing unit 10C. The ROM data reading unit 10D, which reads the remote control code format by designating an address to the external ROM 60, and the data code value assigned to the key among the formats output from the ROM data reading unit 10D, are transmitted to the infrared transmitting unit. And a format output section 10E for outputting to 80).

The key arrangement of the remote controller configured as described above is shown in FIG. 3, and as shown therein, a device selection key for selecting a device to be controlled, a power key, a volume up / down key, a channel up / down key, etc. A basic key, a numeric key, a normal key made up of character keys, and memory keys, wherein the memory key portion is covered by a lid to which a normal key is attached.

The operation and effects of the universal remote controller will be described based on the flowcharts of FIGS. 4 and 5.

The key function memory method of the present invention is classified into two types. The data code value in the remote control code format stored using the data up / down key is increased or decreased by a predetermined step to select a desired function. The method of memorizing the data code value in the key of the desired position, and the method by which the user refers to the manual and inputs the number of the required function by pressing the numeric key or the letter key and memorizing the value in the key of the desired position have.

In the first method, in the code setting mode, the required format among the remote control code formats registered inside the remote control is set in a predetermined manner, and the data code value in this format is changed from the minimum value to the maximum value by pressing the data up / down keys. It increases or decreases in stages and sends and decreases the data code value as an infrared signal, and if it matches the function desired by the user, the code value at that time is stored in an arbitrary key and used.

At this time, if the selected data code value is the same as the data code value already stored in a key or is outside the upper and lower limits of the data code stored in the remote controller, the data code is increased or decreased by a predetermined step.

For data up / down key, use the volume up / down key or channel up / down key, and press the key in the order of setting key → device selection key → data up / down key → memory key → setting key. M01-M20), and pressing the power key while increasing or decreasing the data code value outputs the current code value, so that the current key function can be checked.When the memory is completed, the light emitting diode LED1 of the display unit 70 Flashes.

4 is a control flowchart showing a key function memory method using the data up / down keys.

First, the microcomputer 10 checks whether there is a key input in step 101, and if there is a key input, determines whether the setting key is pressed in step 102, and sets the code in step 103 if the setting key is pressed. Indicates mode.

If there is no key input again in step 104, if there is no key input, the time counter (15 second setting) is operated in step 105, and it is determined whether the time set in the counter in step 106 has elapsed. In step 107, the time counter value is cleared.

If the data up key is pressed in step 108, the data code value of the remote controller is increased by one in step 109, and in step 110, the upper limit of the data code is read from the external ROM 60 in step 110. The upper limit value is compared with the data code value of the remote control, and if it is larger than the upper limit value of the data code value of the remote control, the data code value of the remote control is decreased by one, and if the data code value of the remote control is smaller than the upper limit value, the step ( In step 113, the data code at that time is sent out, and the process is repeated from step 104.

If the data down key is pressed in step 114, the data code value of the remote controller is decreased by one in step 115, and the lower limit value of the data code is read from the external ROM 60 in step 116 in step 117. It is determined whether the data code value of the remote controller is "0" or smaller than the lower limit value. If the data code value of the remote controller is more than the lower limit value, the data code at that time is sent out in step 113, and the data code value is "0". If it is less than the lower limit, the process is repeated from step 104.

If the data up / down key is not pressed, the power key is input in step 118. If the power key is pressed, the current data code is sent in step 119. In step 120, the power key is pressed. If any other key is pressed, the current remote control data code value is stored in the memory allocated to the key pressed in step 121, and is repeated from step 104.

If the setting key has not been pressed in step 102, it is determined whether the memorized key has been pressed in step 122, and if the memorized key has been pressed, the data code stored in the memory of that key is stored in step 123. And if the memorized key has not been pressed, performs the function assigned to the pressed key in step 124. On the other hand, in the second method, in the code setting mode, the required format among the remote control code formats registered inside the remote controller is set, and the data code in the format is displayed by the user looking for the required function and finding the required function number specified in the manual. Press a numeric key or a character key to enter it, and then press any key you want to memorize, and the key will output a data code with the function corresponding to the entered number.

For example, if you have any key or memory to have the power on / off function of your Sony TV, the format number of your Sony TV is "1 2 3" in the user manual, and the power on / off function of your Sony TV Assuming that the number is " 3 4 ", the model is set by pressing the keys in the order shown in FIG. 6A, and then the power key is registered by pressing the keys in the same order as in FIG.

Then, if any key is pressed later, the remote control will transmit a data code that has the power on / off function of the Sony TV.

5 is a control flowchart showing a key function memory method using the manual and numeric keys.

The microcomputer 10 checks whether there is a key input in step 201, and if there is a key input, determines whether the setting key is pressed in step 202, and if the setting key is pressed, enters the code setting mode in step 203. Display.

If there is no key input again in step 204, if there is no key input, the time counter (15 second setting) is operated in step 205, and the time set in the counter in step 206 has elapsed or the setting key is pressed. If there is a key input within a predetermined time or if the setting key is not pressed, the time counter value is cleared in step 207.

In step 208, it is determined whether the code input completion flag is 1, and if it is not 1, in step 209, it is determined whether the numeric key or the character key is pressed, and if the numeric key or the character key is pressed, steps 210-220. Check the order in which the keys are pressed, sequentially convert the key numbers or characters into binary numbers, store 4 bits of data per key in 16 bit memory in sequence, and then complete the code input in step 221. Set the flag to 1.

If the code input completion flag is 1 in step 208, 16-bit code data is stored in the memory area allocated to the key pressed in step 222, and the code input completion flag is cleared to 0 in step 223. < Desc / Clms Page number 6 > The process then repeats from step 204.

If the setting key has not been pressed in step 202, it is determined whether the memorized key has been pressed in step 204, and if the memorized key is pressed the data code stored in the memory of that key in step 225. And if the memorized key has not been pressed, performs the function assigned to the pressed key in step 226.

As described above, the present invention uses a data up / down key to select a desired function while increasing or decreasing a code value, or inputs a function number specified in a manual by pressing a numeric key, and then stores the input code value in a key of a desired position. This reduces the size of the remote control and simplifies key layout, effectively controlling a wide range of products.

Also, since the function currently memorized can be checked during the key program, there is an effect that the convenience of use can be achieved.
