The present invention relates to a mouse system for a wireless television (hereinafter referred to as a TV) and a personal computer (hereinafter referred to as a PC) and a method of implementing the same, and more particularly, to a wireless TV and a PC suitable for easily manipulating the movement of an indicator. The present invention relates to a mouse system and an implementation method thereof.

In a conventional TV remote controller operation, as shown in FIG. 1, when a user presses a desired button of the TV remote controller, the button interprets the corresponding signal on the remote controller and the code signal is specifically reserved, for example, mute = '010110'. It generates a pulse of the back in the infrared. This signal is received by a sensor attached to the TV receiver and interpreted by a decoder inside the TV receiver so that the microcomputer can perform the corresponding operation.

However, in such a conventional technology, as the functions are diversified, it is difficult to operate the remote controller, and the size of the remote controller is increased, which makes it difficult to operate with one hand.

Accordingly, an object of the present invention is to solve the above problems, and as the interface method used in the TV and the PC is switched to the GUI (Graphic User lnterface) method, the mouse system for the wireless TV and the PC for easily manipulating the movement of the indicator. And a method of implementing the same.

In order to achieve the above object, a method of implementing a mouse system for a TV and a PC according to the present invention includes installing a sensor at a predetermined position of a TV screen to move an indicator located on the TV screen around a sensor irradiated with an infrared pulse string output from a remote controller. It is characterized by.

In addition, the mouse system for TV and PC according to the present invention includes a comparison unit for comparing signals from a plurality of sensors attached to a predetermined position of the TV screen or PC screen; A selection unit for selecting a direction for the indicator to move by using the signal output from the comparison unit as a selection signal; A register for temporarily storing the direction information output from the selection unit; By adjusting the GUI display from the direction information stored in the register, the indicator is adjusted to move the position of the indicator on the TV or PC screen, or when another menu is selected again, the movement of the currently in progress indicator is stopped and the operation on the selected menu is performed. Micom for performing; And an ID decoder for interpreting and applying the infrared pulse train to the microcomputer when the infrared pulse train for the menu selected by the remote controller is input to the sensor.

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

2 is a view for explaining a mouse system according to the present invention.

Referring to FIG. 2, when the 'MENU' selection key of the remote controller is pressed, the 'MENU' screen is overlapped with the TV screen on the TV screen or the PC screen, and the desired menu is reflected on the U, R, D, L The desired operation can be performed inside the TV receiver by moving the on-screen cursor to a desired place and pressing the 'MENU' key on the remote controller again.

It should be noted that the beam width is designed so that the beam width of the remote controller is illuminated on each of U, D, L, and R, or only two sensors such as L, U, or R, D. In addition, the timer is built so that the infrared pulse train is continuously generated by the remote controller while the indicator is moving so that the generation of the infrared pulse train is stopped when the remote controller is not operated during a predetermined time. However, the U, R, D, and L are infrared sensors.

3 is a block diagram according to the first embodiment of the mouse system according to the present invention.

The first comparator 1 and the second comparator 2 compare the U, D signals and the L, R signals, respectively, and determine which ones are selected as a whole, and apply the resulting signal to the selector 3, that is, the first comparator. The comparator 1 outputs '1' if the U signal is greater than or equal to the D signal and '0' if the U signal is less than the D signal. On the other hand, the second comparator 2 outputs '1' if the L signal is greater than or equal to the R signal and '0' if the L signal is less than the R signal to the selector 3.

The selector 3 selects one of Y0, Yl, Y2, and Y3 using the output signals of the first comparator 1 and the second comparator 2 as a selection signal, and stores the selected information in the register 4. .

The microcomputer 5 adjusts the indicator by adjusting the GUI display 6 based on the information stored in the register 4, so that the indicator position on the TV screen 8 can be moved. If the infrared pulse string for the selected menu is input to any one of U, D, L, and R through the negative OR circuit 11, the IR decoder 12 interprets the micro pulse according to the output of the negative OR circuit 11. Send to the interrupt routine of 5) to stop the movement of the indicator currently in progress and perform the operation for the selected menu. In addition, in FIG. 3, reference numeral 7 is an adder, 8 is a TV screen, 9 is a synchronization circuit, and 10 is a TV signal generator.

4 is a block diagram showing a remote controller used in the present invention.

Since the conventional remote control generates a pulsed infrared signal only while pressing a key, it is necessary to continuously press the key in the case of continuous movement, but the remote controller used in the present invention does not use a key for a predetermined time by installing a timer 21. Infrared pulse output automatically stops.

In addition, in order to adjust the width of the light emitted from the infrared light emitting unit 24, the lens 25 is attached to adjust the beam width of the remote controller as shown in FIG. That is, in Fig. 5, by being within W, it is possible to prevent three or more sensors such as U, R, D, and L from being selected at the same time.

In addition, the fourth infrared diode (LED) emits light according to the signal of the infrared light emitting unit 24, the matrix circuit 22 outputs a signal according to the key operation, the pulse generator and code encoder 23 is a matrix The signal of the circuit 22 is encoded and the pulse signal is applied to the infrared light emitting unit 24.

6 is a block diagram according to a second embodiment of a mouse system according to the present invention.

In the first embodiment shown in FIGS. 2 and 3, four sensors U, R, L, and D are installed on all sides of the TV screen 8, among which U and L, D and R are removed, Remove U and R, or D and L, and adjust the indicator with the two sensors. That is, the indicator is moved depending on which sensor is irradiated with infrared rays.

6 illustrates an example in which only L and U sensors are used. At this time, compared with FIG. 3, the driving principle is the same as that of FIG. 3 with the first comparator 1 and the second comparator 2 being removed.

In addition, in order to adjust the beam width irradiated from the remote control, the lens 25 is installed to enable the focus adjustment in front of the IR diode (LED) to adjust the beam width.

As described above, the mouse system for the wireless TV and the PC and the method of implementing the same according to the present invention can be used in a GUI, so that the user can quickly understand and easily operate the system.

In addition, in the related art, when the remote controller is complicated, a desired operation can be performed only through a complicated step. However, as the present invention, the user can easily switch to another operation by moving only the indicator to select the required operation from the menu provided on the TV screen. In addition to the TV, there is an advantage that can be easily applied to operate the interactive TV, which is a multimedia TV.
