Remote control system with custom function keys

The present invention relates to a remote control system of a home appliance, and more particularly, to a remote control system having a user-specified function key that enables a user to arbitrarily set and use the functions of some of the button keys provided in the remote control device. will be.

Recently, with the diversification and specialization of consumers' purchase, products with more diverse functions have become more competitive in the home appliance sector, and accordingly, the direction of product development is diversified and specialized. ought.

In addition, the remote control system, which was conventionally applied only to some expensive home appliances, has recently been extended to general home appliances due to the low cost of parts due to technology development and the development of products focused on user convenience. Is showing.

Meanwhile, various and complicated functions of recently released home appliances can be operated by using a limited button key provided in the remote control device, and a user can select a desired function by operating a button key of the remote control device. Various efforts have been made to avoid recognition that the operation is complicated, and one of them is a menu type key input method commonly used in general home appliances.

However, since the menu-type key input operation requires the user to navigate through the hierarchical structure of the tree shape in order to select a desired function, the key input procedure may be somewhat inconvenient for the user. Since there is no simplification of the key input procedure for a function that is frequently selected, it is cumbersome every time a key operation is performed.

The present invention has been made in view of the above circumstances, and provides a remote control system having a user-defined function key that allows a user to arbitrarily set and use the functions of some of the button keys provided in the remote control device. The purpose is.

1 is a block diagram showing an internal configuration of a remote control system having a user-defined function key according to an embodiment of the present invention, which is representative of a television receiver which is the most widely used among home appliances equipped with a remote control function. As an example.

In the drawing, reference numeral I denotes the configuration of the remote control apparatus side, and reference numeral II denotes the configuration of the main body of the TV receiver.

On the other hand, the remote control device (I) includes a key matrix circuit (1) configured by arranging a plurality of button keys in a matrix structure including a predetermined number of extension keys (K21 to K24) in which a user can arbitrarily set the function thereof; A code data storage unit 2 storing code data corresponding to each button key of the key matrix circuit 1, an oscillator for generating a predetermined frequency signal, and a light emitting diode for transmitting an infrared light signal. (LED), a switching transistor (Q) for flashing the light emitting diode by driving on / off in accordance with a predetermined control signal, and the selected key position when an arbitrary button key of the key metrics circuit 1 is selected by the user. A remote controller IC (3) for driving control of the switching transistor (Q) on the basis of the data read out from the code data storage unit (2) and the expansion keys (K21 to K24); Extended code storage unit 4 for function designation is provided.

Meanwhile, the structure of the TV receiver main body (II) is as follows.

First, a TV tuner main body (II) tunes an antenna 21 for receiving a broadcast and a broadcast signal of a channel selected by a user among the broadcast signals received by the antenna 21 to output an intermediate frequency signal of the corresponding channel. (22), an IF amplifier section 23 for amplifying the intermediate frequency signal output from the tuner 22 to a predetermined level, and the signal amplified by the IF amplifier section 23 with an image intermediate frequency signal (PIF) and audio. A P / S separator 24 for separating and outputting the intermediate frequency signal SIF is provided.

In addition, the image detector 25 detects only the image signal from the image intermediate frequency signal PIF separated by the P / S separator 24 and outputs the composite image signal CVS, and the image detector. An image processor 26 is provided which outputs R, G, B color tone signals and luminance signals Y on the basis of the composite video signal outputted from (25).

On the other hand, in addition to the receiving unit 27 for receiving the infrared signal transmitted from the light emitting diode (LED) of the remote control device (I) and converts it into an electrical code signal and the code signal output from the receiving unit 27 According to the command information storage unit 28 storing the internal command information of the corresponding TV set, and the code data applied from the receiving unit 27 based on the data stored in the command information storage unit 28. In accordance with the microprocessor 29 for controlling the operation of the overall device, and the extended command information storage unit 30 for setting the function key by the user designation according to the present invention, according to a predetermined control signal from the microprocessor 29 An OSD generator 31 generating and outputting a predetermined OSD pattern signal for outputting a subtitle, and mixing the output signal of the OSD generator 31 with the output signal of the image processor 26; Through W CRT driving unit (not shown) is provided with a mixer (MIXER) for outputting toward the CRT.

The TV body (II) receiving unit 27 receives the infrared signal transmitted from the light emitting diode (LED) of the remote control device (I), converts it into an electric code signal, and outputs it to the microprocessor 29. When the microprocessor 29 indexes the code signal applied from the receiver 27 in the command information storage unit 28 and confirms that the code value is determined as an index result, the microprocessor 29 drives the OSD generator 31. By outputting predetermined OSD pattern data, as shown in Fig. 2, a guide caption for setting a user-specified key is output on the CRT screen.

The guide caption is divided into two regions. For example, as shown in FIG. 2, the position of the extension key to which the function is assigned by the user is displayed one by one. On the left side of the screen, Each function to be set as a function is displayed corresponding to the serial number.

Meanwhile, referring to the OSD guided subtitle displayed on the screen, the user operates the up / down key or the numeric key provided on the keypad of the remote control unit I to select a function to be used as the corresponding extension key, When K3) is pressed, the remote controller IC 3 reads code data corresponding to the extension key pressed by the user from the extension code storage unit 4 and switches the switching transistor Q based on the read information and the function selection information. By driving, the infrared signal is sent to the TV body (II) side.

On the other hand, the TV processor (II) side microprocessor 29 corresponds to the code data of the extension key applied through the receiver 27 and the command information of the function specified by the user to the extended command information storage unit 30. Registration will be set.

Then, when the user inputs a user command according to the selection by pressing the extension key in the state where the user selects the function key K1, the remote controller IC 3 stores the data stored in the extension code storage unit 4. The infrared signal corresponding to the extended key pressed by the user is transmitted to the TV main body based on the bar. When the extended key code data contracted through the receiving unit 27 is applied, the microprocessor 29 receives the extended command information. By executing the command specified by the user to be executed based on the data registered in the storage unit 30, the command processing operation according to the extension key setting is executed.

That is, according to the above embodiment, it is possible to realize a remote control system having a user-specific function key that allows a user to arbitrarily set and use the functions of some of the button keys provided in the remote control device.

Meanwhile, the present invention is not limited to the above embodiments and can be variously modified within the scope not departing from the technical gist of the present invention.
