Description

{THE CONTROL APPARATUS OF ESTABLISHMENT METHOD FOR USING CODE INPUT ON UNIVERSAL REMOTE CONTROLLER}

The present invention relates to a universal remote controller, and more particularly, to enter a code setting mode through a combination input of any two designated keys, and a code for each controlled device is stored in one memory area. The present invention relates to a control device setting method using a code input in a universal remote controller that is randomly stored in a remote controller.

The universal remote control is a remote control device that can control various devices such as televisions, video cassette recorders (VCRs), satellite broadcasting converters (SAT) and various functions with a single remote control. It is developed and used.

In order to use such a universal remote control, a user must first set a universal remote control suitable for a controlled device to be controlled.

Setting method of universal remote control includes code input method that directly finds and inputs code assigned to the controlled device to be controlled by the user in the user manual of the universal remote control, that is, the code matching the frequency of the controlled device. There is an automatic setting method for setting a code for a controlled device by repeatedly driving a setting key provided on a remote controller without inputting a code.

Among the setting methods of the universal remote controller divided as described above, the code input method programmed in the conventional universal remote controller is required to complete the code setting operation for the desired controlled device through several steps.

In other words, first press the device selection key of the controlled device, for example, TV, VCR, SAT, etc. to be controlled by the universal remote control, and then simultaneously press a special key to enter the setting mode for a predetermined time to enter the setting mode, and After the mode is entered, the user must directly find and input the code assigned to the controlled device to be controlled by the user manual.

In addition, the conventional code setting method universal remote control allows a predetermined code to be stored in order in each controlled device in a memory space on the remote control.

That is, codes corresponding to a TV are arranged and stored in a predetermined order in a memory space corresponding to a TV area, and codes corresponding to a VCR are arranged and stored in a predetermined order in a memory space corresponding to a VCR area.

Therefore, even the same code number is used because it is stored in a separate memory area for each controlled device.

That is, the TV code '001' and the VCR code '001' are used as separate codes, which may result in a user inputting a code of another controlled device by mistake during a code setting operation.

The present invention has been invented to solve the above problems, the object of which is to code through a combination input of any two keys specified without key input for selecting the controlled device to be controlled in the process of setting the universal remote control By entering the setting mode, it is possible to enter the user code setting mode simply and easily.

In addition, the present invention allows a code including information on each controlled device to be set to be randomly stored in one memory area to exclude the memory space required for each device, providing quick response and easy The convenient setting operation allows the user to provide promptness and convenience in setting codes for the desired controlled device.

Figure 2 is a flow diagram of one embodiment for the process of entering the code input mode in the universal remote control according to the present invention.

Figure 3 is a flow diagram of an embodiment for performing the control device settings via code input in the universal remote control according to the present invention.

The present invention for realizing the above object comprises the steps of determining whether a key input is detected in the standby mode of the universal remote control; Determining whether a key combination is specified for code setting when a key input is detected; Transmitting a control frequency for the selected key if it is determined that the key combination is not specified, and entering a code setting mode of the controlled device to be controlled if the key combination is specified; Determining whether a key input is detected within a predetermined time period set in the code setting mode; If the key input is not detected within a predetermined time, exiting the code setting mode of the controlled device and entering the standby mode; and if the key input is detected within the predetermined time, determining whether the input key is a numeric key; If the numeric key is not input, exits the code setting mode of the controlled device and enters the standby mode, and if the numeric key is input, determining whether the total number of input keys is a set number; Repeating scanning of key inputs if the set number of key inputs is not set; transmitting a power control frequency for a corresponding code if the set number of key inputs is input; If the input of the confirmation key signal is not detected by determining whether the input of the key signal for confirming the code setting after the transmission of the power control frequency is detected, the above-described process is repeated. Provided is a control device setting method using code input in a universal remote controller, the method comprising storing control frequency data in a memory area.

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

For example, in the initialization standby mode of the universal remote control in which the primary battery or the secondary battery is housed in a power supply unit not shown in the universal remote control having various function keys as shown in FIG. 1 (S101) (S102), the microprocessor The control means consisting of the scanning of the input of the key signal (S103), and determines whether the input of the key signal is detected (S104).

If the determination of S104 does not detect the input of the key signal, the controller returns to S102 to scan the input of the key signal as described above in the standby mode S102, and if the input of the key signal is detected, the detected key signal It is determined whether is a designated key combination for code setting (S105).

If it is determined in S105 that the key combination is not designated for the code setting, it is determined that it is an input of a general control signal for controlling any controlled device function, and the control frequency for the corresponding key is transmitted and then the process of S102 is performed. Return to enter the standby mode (S106).

However, if it is determined in S105 that the key combination is designated for the code setting, the apparatus enters the device code setting mode which is the controlled device (S107).

The specified key combination for the code setting may be variously specified according to the setting of the program by combining two or more arbitrary keys included in the universal remote controller. It must be pressed simultaneously for a certain time to enter the code setting mode.

As shown in FIG. 3 attached to the detection of any key combination designated as described above, when entering the device code setting mode as the controlled device (S201), the user wants to control in the user manual (user manual). Find the device code for the controlled device in the brand and input the code (S202).

At this time, the microprocessor which is a control means in the universal remote control scans the key input (S203) and determines whether the key input is detected within a predetermined time, for example, 3 seconds (S204), and the key input is not detected within the predetermined time. If not, enter the standby mode after exiting the code setting mode, and if a key input is detected within a predetermined time, it is determined whether the input key signal is a numeric key for code input (S205).

If it is determined that the numeric key is not input, the microprocessor as a control means enters the standby mode after ending the setting mode, and if it is determined that the numeric key is input, the predetermined number of the total number of the input numeric keys is set. That is, it is determined whether three to four input (S206).

If the total number of numeric keys to be input is equal to or less than the predetermined number, the process returns to step S203 until the total number of numeric keys to be input is equal to or greater than the predetermined number, and the total number of numeric keys to be input. When the number is detected as a predetermined number, three to four, the power supply data frequency for the selected code is transmitted (S207).

At this time, the user performing the code setting determines whether the power of the controlled device to be controlled is turned on / off to determine whether to proceed with the next step.

That is, when the power of the controlled device to be controlled is turned on / off, since the currently input code is a code in which the control frequency of the controlled device is matched, the user sets a code through a confirmation key and the power of the controlled device is If it is not turned on / off, the currently input code is not a code to which the control frequency of the controlled device is matched, and the above process is repeated for the input of the next code.

Therefore, the microprocessor, which is a control means in the universal remote controller, determines whether a confirmation key for completing code setting is input (S208).

In the determination of S208, it is determined whether the input of the confirmation key is the input of the numeric key (S209). If it is determined that the input of the numeric key is input, the process returns to the process of S203 and repeats the above-described process to set the code. If key input is repeatedly searched and it is judged that the numeric key is not input, the code setting mode is terminated and then the standby mode is entered.

However, when the input of the confirmation key is detected in the determination of S208, the microprocessor as the control means determines that the corresponding code value inputted by the numeric keys 3 to 4 is a code in which the control frequency of the controlled device to be controlled is matched. The control frequency data of the corresponding code is stored in the memory (S210).

The above operation has been described as an operation for one controlled device, and code setting for various controlled devices, for example, TV, VCR, SAT, and AUDIO, is also apparent through the above-described process.

In addition, in the control frequency code setting for each controlled device described above, a control inputted when codes are set for different controlled devices such as TV, VCR, SAT, AUDIO, etc. and products of different manufacturers. The microprocessor, which is a means, randomly stores the codes input to one memory area according to the input order or the bit string of the code values.

For example, assume that a user manual is set to a code as shown in Table 1 below.

manufacture company TV VCR SAT Samsung 1031,1121,1231 1442,2002,3402 1113,1323,1413 LG Electronics 1331,2231,3031 1342,2142 3033,4033,1443 Daewoo Electronics 1022,1032,1131 0242,1012,2312 0213,0223 Sony 4301,4120,4502 3025,3127,3792 2475,2256,2136 sharp 4011,4341,4458 3785,3645,3256 2496,2578,2875 Hitachi 5689,5769,5423 4897,4321,4125 2353,2543,2802

Therefore, the user inputs the 4-digit code for the controlled device from the above user manual through the above-described process, and sets the code of the controlled device to be controlled. Assuming that control frequencies for the VCR and Sharp SAT of LG Electronics are set, for example, '1031', '1342', and '2496' are randomly stored in each code stored in one memory area.

As described above, the present invention reduces the device key input step for entering the code setting mode, and does not sequentially store codes for each controlled device stored in the memory for each device. By including information on the device in each code and randomly storing the data regardless of the device, the user can easily and conveniently finish the code setting in a short time.
