CONTROL CODE SETUP SYSTEM OF UNIVERSAL REMOTE CONTROLLER AND METHOD THEREOF}

The present invention relates to a remote control device which is a remote control device, and more particularly, a control frequency code for an arbitrary remote control device in a universal remote control that remotely controls two or more controlled devices different from a manufacturer and a product through a single remote control. The present invention relates to a control code setting device and a method of a universal remote controller for setting a control frequency code by checking whether matching of control frequency codes with respect to respective activation keys corresponding to a corresponding controlled device when setting the control frequency code.

In general, in order to remotely control operations of two or more TV receivers, VCRs, and cable broadcasting receivers having different manufacturers and product specifications, the remote controllers provided for each corresponding product are classified by the manufacturer and the product. Should be used.

Therefore, the operation method of the remote control is different for each manufacturer and the product has a very troublesome disadvantage in selecting and controlling any product.

In addition, different control frequencies are applied to each manufacturer and each product, so even if the same product, for example, a TV receiver, is not compatible with other companies' products, a plurality of remote controllers corresponding to each manufacturer and each product may be used. There is a cumbersome problem to possess and use.

In order to solve this problem, various kinds of universal remote controllers that can control various devices and various functions such as TV receivers, VCRs, cable broadcasting receivers, and the like with one remote controller have been developed and used.

In order to use the universal remote control, the user must first set the universal remote control according to the controlled device to be controlled. For this purpose, the user's manual provided by the universal remote control is assigned to the controlled device to be controlled by the user. The control frequency code, that is, the control frequency code matched with the corresponding controlled device can be directly found and inputted, or the control frequency code for the controlled device can be automatically set by repeatedly driving the setting key provided on the remote controller. The method is being applied.

In setting the control frequency code corresponding to the controlled device to be controlled to the universal remote controller as described above, the microprocessor, which is a control means of the universal remote controller, transmits only a control frequency code corresponding to the power key of the controlled device. The controller observes the response of the controlled device to complete the setting of the control frequency code for the controlled device when the response of the power on / off of the controlled device is observed.

That is, first press the control key of the controlled device to be controlled by the universal remote controller, for example, a TV receiver, a VCR, a cable broadcast receiver, etc., and then simultaneously press a special key for entering a setting mode for a predetermined time at the same time. After entering into the setting mode, the predetermined mode is repeatedly driven to send only the control frequency code corresponding to the power key repeatedly, and to detect the power on / off response of the controlled device to be controlled by the user. In this case, the setting of the control frequency code for the corresponding controller is completed through the input of the setting key.

In the case of the conventional universal remote controller as described above, a method of setting a matching frequency for a controlled device to be controlled by transmitting only a control frequency code corresponding to a power key is applied. The frequency code is set the same but differently set for other function keys.Therefore, general functions for performing other functions when setting the control frequency code of the controlled device using only the power control frequency code. The disadvantage is that it does not respond to the control frequency code of the key.

Therefore, in this case, the user has a troublesome problem of re-checking whether the function control for other general keys is normally performed after again performing the control frequency code setting operation on the corresponding controlled device.

In addition, there is a problem that the user is distrusted to the universal remote control due to the occurrence of the above problem.

The present invention has been invented to solve the above problems, the object of which is to control the target by inputting any key combination specified after entering the control frequency setting mode when setting the control frequency code for any controlled device All keys corresponding to the function control of the device are activated so that the control frequency codes for each key are sequentially outputted, thereby searching for matching of the control frequency codes for all keys corresponding to the corresponding controlled device. The control frequency code can be set.

In addition, the present invention is to automatically output or step output the control frequency code for each function sequentially until the response to the activation key in the activation state of all keys corresponding to the function control of the controlled device.

In addition, the universal remote control according to the present invention configures a dedicated key for this separately, so as to be implemented through the screen of the touch panel type remote controller.

The present invention for realizing the above object

The present invention provides a method for setting a control frequency of a universal remote control, comprising: scanning a key input in a standby mode to determine whether an arbitrary key input is detected; Maintaining a standby mode if any key input is not detected, and determining whether a predetermined key combination for entering the program mode is detected if any key input is detected; If it is determined that the key combination is not specified, operating the controlled device by transmitting a control frequency code for the corresponding key, and entering a program mode when the key combination is designated and pressed for a predetermined time; Determining whether any controlled device selection is detected while entering the program mode; Determining whether an activation key input for the corresponding controlled device is detected when the selected controlled device is detected; Determining whether an automatic or step scan mode is designated after entering an activation mode for the corresponding key when an activation key input for the corresponding controller is detected; When the automatic or step scan mode setting is specified, the activated control frequency code for the corresponding controlled device stored in the memory is sequentially output, and it is determined whether a predetermined key is required to store the control frequency code. Process and; And storing a control frequency code corresponding to a key currently activated in the selected controlled device when the designated arbitrary key requesting storage of the control frequency code is input, and then exiting the program mode. Provides a control code setting method.

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

As can be seen in Figure 1, the universal remote control according to the present invention, as can be seen in the accompanying Figure 1, any controlled device different from the manufacturer and the product, for example, TV, VCR, SAT, AUDIO, etc. Control key selection key 10 for selecting a corresponding controlled device when a control frequency code is set, and a first function of selecting power control, channel up / down, and volume up / down of the selected controlled device. Key 20, a numeric key 30 composed of 0 to 9, and a second function of selecting a screen setting selection control of the selected controlled device and controlling various functions of the VCR when the controlled device is selected as a VCR. Entering the setting mode of the control frequency code for the key 40 and any controlled device and activating the various function keys related to the corresponding controlled device in the state in which the mode is entered, and sequentially the control frequency code for each function key. sign The third function key 50 selects automatic or step sending.

In the case of the third function key 50, the application is variable according to the developer and the designer of the program. For example, an 'OK key' for selecting an entry and exit of an arbitrary control frequency code setting mode; 'UP key', which selects to sequentially auto-scan the control frequency code for each activation key of the controlled target controlled device, and sequentially steps the control frequency code for each activated key of the controlled target controlled device 'RIGHT key' to select scan output and 'LEFT and DOWN key' to select movement of each memory area in the activated state that sequentially outputs control frequency codes for each activation key of any controlled device to be controlled. do.

Although not shown in the case of the internal hardware configuration for the universal remote control according to the present invention as described above, in the existing conventional configuration further comprises a matrix associated with the third function key 50, the control means micro An algorithm is further set in the processor to activate function keys corresponding to the controlled device according to the present invention so that the control frequency code can be output automatically or in a stepwise manner.

According to the present invention, an operation of activating function keys corresponding to a corresponding controlled device and outputting of the control frequency code in a process of setting a control frequency code for a controlled device is performed as follows.

As shown in FIG. 1, the control unit selection key 10, the first function key 20, the numeric key 30, the second function key 40, and the third function key 50 are provided. In the standby mode in which a primary battery or a secondary battery is accommodated in a power supply unit not shown in the remote control unit and power is supplied to each portion (S101), the microprocessor, which is a control unit of the universal remote control, scans an input of a key signal ( In step S102, it is determined whether an input of an arbitrary key selection signal is detected in step S103.

If the input of the key signal is not detected in the determination of S103, the method returns to S101 to scan the input of the key signal as described above in the standby mode (S101), and if the input of the key signal is detected, the key signal is analyzed. (S104), it is determined whether a specified arbitrary key combination which is to set the control frequency code for the controlled device which is a product of an arbitrary manufacturer is pressed simultaneously (S105).

The specified key combination may be changed according to the design of the algorithm. For example, the 'OK key' provided in the third function key 50 and the 'MUTE key' provided in the first function key 20 may be used. Set it.

If it is determined in the determination of S105 that the key combination is not a designated key combination, it is determined that the current control frequency code is a key selection for controlling a function of an arbitrary controlled device to which the current control frequency code is matched, and the control frequency code for the corresponding key is transmitted. The corresponding function of the target controlled device can be performed (S108).

If it is determined in the determination in S105 that the key combination is a combination of the 'OK key' and the 'MUTE key', whether the pressed combination of the two keys has been pressed for a predetermined time or more, for example, 3 seconds or more. It determines (S106).

If it is determined in step S106 that it has not been pressed for more than a predetermined time, the program returns to the process of S101 to maintain a standby mode, and if it is determined that it is pressed for more than a predetermined time, a program for setting a control frequency code for an arbitrary controlled device. The mode is entered (S107).

As described above, when the universal remote controller enters a program mode for setting a control frequency code for an arbitrary controlled device, the user can select any controlled device, for example, a TV, configured in the controlled selector 10. Select one from VCR, SAT, and AUDIO.

Accordingly, as can be seen in the accompanying Figure 3, the microprocessor as a control means in the universal remote control in the program mode (S301), within a predetermined time set by scanning the key signal input from the control unit selection key 10, For example, it is determined whether a selection of any controlled device is detected within 3 seconds (S302).

If any control device selection is not detected within the predetermined time set by the determination of S302, the program mode is terminated. If the selection of the control device is detected within the set time, the activation key for the corresponding control device is set within the predetermined time period. It is determined whether it is input (S303).

That is, for example, when the controlled device selected by the controlled device selection key 10 is a TV receiver of an arbitrary manufacturer, an activation key applied to the TV receiver is configured in the first function key 20. A power key, a channel up / down, a volume up / down, a mute key, and a numeric key (30) consisting of 0 to 9, and the controller selected by the controller selection key (10) is a VCR of an arbitrary manufacturer. In this case, the activation key applied to the VCR includes a power key configured in the first function key 20 and a play key (▶) configured in the second function key 40, a fast forward key (▶▶), and a fast forward back. Keys (◀◀), recording key (◎), playback stop key (■) and pause key ( ∥ ).

If the input of any one of the above activation keys for the corresponding controller selected within the predetermined time set by the determination of S303 is not detected, the program mode is terminated and the selected controller is selected within the predetermined time period. When an input of one of the activation keys is detected, the microprocessor sends a control frequency code (data) for the selected activation key to the controlled device to be controlled (S304).

After the activation key for the corresponding controller selected as described above is selected, all the activation keys for the corresponding controller selected from the function keys configured in the third function key 50 are automatically scanned from the memory area to control the corresponding control frequency code. In step S305, it is determined whether an input of a designated arbitrary key for transmitting a key, for example, an 'UP key' is detected.

When the microprocessor detects an input of a predetermined random key for selecting the auto scan mode, for example, an 'UP key' in the determination of S305, the microprocessor outputs control frequency codes for all activation keys for the selected controller. In step S306, the control frequency code (data) for the product is continuously increased in the forward direction to increase the memory address until the selected corresponding controller responds to the activated key. Is sent (S307).

That is, when the selected controller is, for example, a TV receiver, as described above, all keys related to the function control of the TV receiver are the power key, the channel up / down, the volume up / down, the mute key, and 0-9. The control frequency codes are sequentially output to the numeric keys.

In the process of continuously transmitting the control frequency code (data) until the corresponding controller selected as described above responds to the activated key, an input of another designated key, for example, a 'LEFT key or a DOWN key' is detected. It is determined whether or not (S308).

When the input of the 'LEFT key or the DOWN key' is detected in S308, the address is reduced at the current position of the memory, and the control frequency code (data) for the activation key is transmitted (S309). It is determined whether an input of an arbitrary key, for example, an 'OK key', which designates a control frequency code for the control frequency code is detected (S310).

If the specified arbitrary key signal input commanding the setting of the control frequency code is not detected, the method returns to step S305 to detect whether the 'UP key', which is the designated arbitrary key requiring the setting of the auto scan mode, is detected. The process is repeated, and when an input of a specified key signal, for example, an 'OK key', is detected that commands the setting of the control frequency code, the control frequency code for the selected control unit corresponds to the currently activated key. After saving the code, the program mode ends (S311).

If the input of the 'LEFT key or the DOWN key' is not detected in the determination of S308, it is determined whether an input of another activation key is detected (S312), and if an input of another activation key is detected, the process returns to the process of S304 described above. If the input of the other activation key is not detected, the control frequency code for the selected remote controller is activated at the memory location, according to the input of any specified key specifying the setting, for example, the 'OK key'. After storing the control frequency code corresponding to the key, the program mode is terminated (S311).

Detecting the input of another activation key of S312 selects another activation key for the corresponding controlled device even when the control frequency code for the activation key first selected by the user is seen or not displayed in the corresponding controlled device. This is to allow the user to repeat the desired reaction until the corresponding controller is shown.

This solves the disadvantage that the other general function keys do not perform the specified functions and operations by setting the control frequency code using only the control frequency of the power key in the existing setting method.

If, in the judgment of S305, the designated arbitrary key which commands the setting of the auto scan mode, for example, the input of the 'UP key' is not input, the designated arbitrary key which commands the setting of the step scan mode, for example, the 'RIGHT key' It is determined whether the input of 'S320.

If it is determined in the determination of S320 that the input of the predetermined random key that commands the setting of the step scan mode, for example, the 'RIGHT key', the program mode is terminated after the set time has elapsed, and the input of the 'RIGHT key' is performed. If it is determined, the microprocessor enters the step scan mode (S321) and controls from the memory area each time any designated key, for example, a 'RIGHT key' is pressed, until the selected corresponding controller responds to the activated key. The frequency code (data) is accessed and transmitted one by one in the direction of increasing the address (S322).

As described above, it is determined whether an input of another specified key, for example, a 'LEFT key or a DOWN key' is detected, in the process of transmitting control frequency codes (data) one by one whenever the specified key is pressed (S323). ).

When the input of the 'LEFT key or the DOWN key' is detected in S323, the address is decreased at the current position of the memory, and the control frequency code (data) for the activation key is transmitted (S324). In operation S310, it is determined whether an input of a specified arbitrary key, for example, an 'OK key', is detected that commands the setting of the control frequency code.

If the above-mentioned arbitrary key signal input commanding the setting of the control frequency code is not detected, the process returns to step S305 to determine whether the 'UP key', which is the designated arbitrary key requiring the setting of the auto scan mode, or the step scan mode. The above-described process is repeated by detecting the input of the 'RIGHT key' which commands the setting of, and when the predetermined arbitrary key signal which commands the setting of the control frequency code, for example, the input of the 'OK key' is detected, After storing the control frequency code for the controller as a code corresponding to the currently activated key, the program mode ends (S311).

In addition, if the input of the 'LEFT key or the DOWN key' is not detected in the determination of S323, the controller returns to S312 to determine whether an input of another activation key for the currently selected controller is detected, and then the operation as described above is performed. To perform.

As described above, in the present invention, when a control frequency code for an arbitrary controlled device is set in a universal remote controller that remotely controls two or more controlled devices different from a manufacturer and a product through a single remote controller, By setting the control frequency code by checking whether the control frequency code is matched with each corresponding activation key, stability and reliability are provided in setting the control frequency code for the controlled device.
