Description

Apparatus and method for controlling peripheral power supply of video cassette recorder

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video cassette recorder (hereinafter abbreviated as VSD), and more particularly to a peripheral power supply control apparatus and method of VSEAL.

By using the head mounted on the rotating head drum, V-Cal magnetizes the video tape which is a magnetic material, and records predetermined video and audio signals or reads the video and audio signals recorded on the video tape, such as a video medium, such as a TV. It is a device that can be output by.

In recent years, by connecting a cable box capable of receiving cable television broadcasts in each home to V-Cal, a wider range of broadcast programs can be viewed and scheduled recording.

On the other hand, in order to watch the contents recorded on the videotape, the V-Cal power source and the TV power source must be turned on together by using a remote controller (hereinafter, referred to as a remote controller) or a key input means formed on an electronic device's own panel. In order to watch cable broadcasting, the cable box power supply and the TV power supply must both be turned on. In addition, it is well known that when the user wants to stop watching VR or cable broadcasting, the above-mentioned devices should be turned off.

Such frequent operation of the device was likely to be cumbersome for the user.

Accordingly, the present invention has been devised in view of this point, and an object of the present invention is to control the power of V-Cal peripheral devices in accordance with the power on / off operation of V-al, thereby reducing inconvenience in using electronic devices. To provide a peripheral power supply control apparatus and method.

That is, the present invention is a method of controlling a peripheral device power supply of V-C that incorporates a power control key code for controlling the power of at least two or more peripheral devices that receive a predetermined key signal from a remote control device. A first step of determining whether a signal is applied; If a power on / off key signal is applied, turning on / off the power of the V-Cal; A third step of reading each embedded peripheral power control key code after performing the second step; And a fourth step of outputting a power control signal corresponding to the read power control key code to each peripheral device.

The above objects and various advantages of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a peripheral device of a VRC 20 according to the present invention (in the present invention, a TV 30 and a cable box 40 are used as examples). The key input unit of the remote controller 10 is shown in FIG. 12) and a transmitter section 14, a receiver section 22, a microcomputer 24, a read only memory (ROM) 26, and a power supply voltage section 28 of the VLC 20, respectively.

As shown, the key input unit 12 in the remote controller 10 is provided with a plurality of function keys (not shown) for controlling the operation of the VRT 20 such as a power on / off key, And a key signal corresponding to the key pressed by the user to the transmitter 14 in the remote controller 10.

The transmitting unit 14 is composed of light emitting means, for example, a light emitting diode (LED), etc., and has a structure in which a key signal provided from the key input unit 12 is converted into an optical signal and transmitted to the VSR 20.

The receiving unit 22 of the VRF 20 receives a light signal transmitted from the transmitting unit 14 of the remote controller 10 by using a photo transistor, etc., and provides the received signal to the microcomputer 24. It consists of.

The microcomputer 24 controls the power supply voltage unit 28 in response to a received signal provided from the receiver 22, for example, a power on / off signal, thereby turning on / off the power of the V200. In addition, the microcomputer 24 reads a key code for controlling the power of the peripheral devices (TV 30 and the cable box 40) from the ROM 26 in response to the power on / off signal, thereby causing the peripheral device 30 to read. Output as, (40).

Hereinafter, a detailed description will be made with reference to a flowchart of FIG. 2 attached to a power supply control process of a peripheral device (TV 30, cable box 40) of a VR 200 according to the present invention. .

Prior to the description, in the ROM 26 according to the present embodiment, power control for controlling the power of at least two or more peripheral devices (TV 30, cable box 40) corresponding to a key signal from the remote controller 10 is performed. It is assumed that the key code is stored.

First, the microcomputer 24 determines whether a power on / off key signal is applied from the remote controller 10 in step S100.

When the power on / off key signal is applied from the remote controller 10, the microcomputer 24 controls the power supply voltage unit 28 to turn on / off the power of the VCal 20 (S102).

At the same time, the microcomputer 24 reads out a key code for controlling the power supply of the television 30 and the cable box 40 embedded in the ROM 26 in step S104.

Therefore, the microcomputer 24 outputs the power supply control signal corresponding to the read power supply control key code to the television 30 and the cable box 40, respectively, thereby turning on / off the television 30 and the cable box 40, respectively. (S106).

In addition, the peripheral device applied to the present embodiment can be applied not only to a TV or a cable box, but also to a DVD (Digital Video Disk) or a personal computer, and the fact is that those skilled in the art It will be easy to see.

As described above, the present invention has the effect of providing the convenience of electronic device operation by controlling the power supply of the peripheral device only by the power supply control of V-CAL.
