Description

Multi-function remote control that displays the operating status of the device

The present invention relates to a multi-function remote control system that can control a plurality of devices with a single remote control, and more specifically, by selecting a device to install a light emitting unit that can indicate that the corresponding device is in use to the viewer The multi-function remote control that displays the operating status of the device to indicate whether is used.

In general, in order to adjust various functions such as volume and channel adjustment of a television, a plurality of function buttons are installed in a main body of the television, and the functions of the television are adjusted by operating the television.

However, the above method lacks convenience because the viewer has to operate a button installed in the television every time one function is adjusted.

In order to improve such a problem, a remote controller that can remotely control each function is born in modern times, and then a multifunctional remote controller that can control a plurality of products with a single remote controller has been born.

The general structure of such a multi-function remote control and the structure and operation of a television receiving the signal of the multi-function remote control and adjusting each function are as follows.

1 is a block diagram showing the configuration of a general multi-function remote control.

As illustrated in FIG. 1, the multifunction remote controller 10 operates a key input unit 11 composed of a plurality of buttons and a key matrix 12 according to the operation of the key input unit 11. That is, when the user presses a desired button, the key metrics 12 are operated, and accordingly, the remote controller micom 13 identifies which function key of the key metrics 12 is operated to provide the remote controller micom 13 with the key. The driving signal is output to the connected crystal oscillator 14. Accordingly, the crystal oscillator 14 oscillates and sends a predetermined signal (pulse signal) to the signal transmitter 15 to output a signal desired by the user.

At this time, the signal generated from the signal transmitter 15 is output in a state where the length of the pulse is different according to the user's button selection (for each function). In addition, in such a remote control, the infrared transmission distance can be adjusted according to which infrared remote transmission angle of the remote control is used. For example, if the infrared sensor having a small angle can send far infrared rays, the infrared rays have a large angle. Using the sensor can transmit infrared light only at close range.

As such, the infrared signal transmitted from the multi-function remote controller 10 is received by the receiver 24 attached to the front of the television. The receiver 24 receives the signal, converts it into an electrical signal, and applies it to the microcomputer 22. The microcomputer 22 is set inside the microcomputer 22 and the electrical signal applied from the receiver 24. The desired function is controlled by determining which function the signal is compared with a plurality of function signals.

By such a configuration, when the viewer presses a setting button among the function keys of the remote control and selects a specific company's specification, the remote control microcomputer 13 causes the viewer to store the manufacturer's data in the data setting unit 16 according to the input. do. That is, the data is stored in the data setting unit 16 such as Daewoo TV, VTR, Daewoo VTR, and CATV, Daewoo CATV. Thereafter, the viewer operates the key input unit 11 again to select the desired device. That is, if the TV is selected, the remote controller micom 13 detects that the TV function key is selected, and accordingly sets the data of the Daewoo TV in the data setting unit 16.

Then, by operating the power key, the volume control keys and the like to watch the TV by operating the function of the Daewoo TV as desired.

After the data setting of the remote controller, the VTR and CATV keys are operated to select data such as Daewoo VTR and Daewoo CATV. After that, the viewer adjusts the desired function to watch.

That is, when the power key, the volume control key, and the like are pressed, the remote controller micom 13 outputs a value of a predetermined pulse signal length to the crystal oscillator 14, and the crystal oscillator 14 controls the remote controller micom 13. Oscillation is generated below to generate a pulse signal corresponding to the length of the volume control function via the signal transmitter 15.

In this way, the receiver 24, which is provided with the volume control pulse signal transmitted from the multi-function remote control 10, on the television main body, receives this signal. The receiver 24 receives a volume control pulse signal, converts the signal into an electrical signal, and applies the signal to the microcomputer 22. The microcomputer 22 transmits the electrical signal applied from the remote controller receiver 24 to the microcomputer 22. By comparing the signals set in the above, it is determined which function the pulse signal is. Accordingly, the microcomputer 22 determines the volume control pulse signal to control the volume control or the power control.

As a result, other products are driven regardless of the intention of the viewer, and thus, the loss of the product and the inconvenience of the viewer are very large.

Accordingly, the present invention was devised to solve the above problems, and an object of the present invention is to display which product function is currently selected in the multi-function remote control, thereby preventing other products from being driven regardless of the viewer's intention. The present invention provides a multi-function remote control that displays the operation status of a corresponding device to reduce product loss and to allow a viewer to easily recognize which product is currently selected, thereby reducing malfunction of a function key.

The remote controller microcomputer 104 which receives the above data stores the data in the data setting unit 106.

After that, if the viewer wants to watch Daewoo TV, the switching mode of the key operation is switched to the TV again. Accordingly, the remote controller micom 104 recognizes that the TV key is pressed, and sets the data of Daewoo TV in the data setting unit 106. At the same time, the remote controller microcomputer 104 applies a driving signal to the TV line connected to the light emitting unit 120.
