Remote control device of PC system using USB of display monitor

The present invention relates to a remote control device of a PC system using a universal serial bus (abbreviated as USB) of a display monitor, and in particular, a remote transmitted to a display monitor incorporating USB control logic. The present invention relates to a remote control device using a USB for controlling a PC and a peripheral device of the PC according to a control signal.

Recently, with the development of optoelectronic technology, a remote controller (hereinafter, referred to as a remote controller) for controlling a PC more conveniently for a user has been provided. For example, if the PC system is a task such as listening to music or watching movies using the PC system in accordance with the trend toward the multimedia trend of providing moving images from simple logical operations or database operations, the PC system is necessarily. This is because it is more convenient to control far away without executing work in close proximity.

Looking at the PC system to which the remote control is applied using the accompanying drawings as follows.

As shown in FIG. 1, in order to remotely control the display monitor 20 to the PC 10, the user presses the keyswitch on the key switch unit 11 attached to the outer case of the remote controller 10. The key switch unit 11 receives the selected key signal from the remote controller microcomputer 12 and encodes the encoded key signal to output a remote control signal.

The remote control signal output from the remote controller micom 12 is applied by the remote controller light emitting unit 13, converts the applied signal into a light signal, and is applied by the remote controller light receiving unit 21 in the display monitor 20. Convert to a signal.

The current signal according to the remote control signal converted by the remote control receiver 21 is decoded and analyzed by applying the signal applied to the signal analyzer 22 to control according to the key signal generated by the remote controller 10. The signal is transmitted to the display monitor 20 or the PC main body 30. For example, if the key signal generated by the remote controller 10 is a signal for adjusting the screen of the display monitor 20, the key signal is applied to the microcomputer 24 through the monitor communication port 23.

The microcomputer 24, which receives a key signal according to the screen adjustment signal through the monitor communication port 23, applies the horizontal and vertical output signals adjusted according to the applied key signal to the deflection circuit 25, and thus the horizontal and vertical signals. The vertical sawtooth wave current is generated in the deflection yoke DY. The horizontal and vertical sawtooth currents generated by the deflection yoke DY determine the scanning period of the image signal applied to the CRT to display an image.

When the video signal applied to the CRT is selected from the remote controller 10 to control the PC main body 30 to execute an application program, the remote controller light receiver 21 and the signal analyzer 22 configured in the display monitor 20 are selected. ), Received from the PC main body 30 through the PC communication port 31 and analyzed by the CPU 32 to select and execute the application program according to the selection of the key signal.

The executed result of the application program is processed into a video signal through the VGA card 33 and generates horizontal and vertical synchronization signals for driving it. The video signals generated through the VAG card 33 and the horizontal and vertical synchronization signals are transmitted to the microcomputer 24 and the video amplifier 26 of the display monitor 20, respectively.

The video signal transmitted to the video amplifier section 26 is sufficiently amplified and applied to the CRT for display, and the display period is displayed in synchronization with the horizontal and vertical synchronization signals transmitted to the microcomputer 24. That is, according to the period of the horizontal and vertical synchronization signal for synchronizing the video signal, the microcomputer 24 generates horizontal and vertical output signals, and the generated horizontal and vertical output signals are transmitted to the deflection yoke DY through the deflection circuit 25. Horizontal and vertical sawtooth wave currents are generated to determine and display the scanning period of the video signal.

Remote control using a remote controller used in such a conventional display monitor is implemented by simple hardware, which is less scalable to PC peripherals, and supports Plug and play (hereinafter, abbreviated as PNP). There is a problem that can not be applied to an operating system that supports multiple tasks.

Therefore, the present invention is an operating system that supports multiple tasks in order to solve the above-mentioned problems. By processing the remote control signal generated from the remote control applied to the display monitor to which USB is applied as a communication protocol for implementing the PNP function, the display monitor as well as An object of the present invention is to provide a remote control device using a USB that can remotely control a PC main body or a peripheral device thereof.
