CONTROLLING APPARATUS AND METHOD OF LEARNING SYSTEM FOR RF REMOTE CONTROLLER}

The present invention is controlled by an RF remote control in a meeting room, seminar, lecture, education, learning (hereinafter referred to as "learning") in a seminar room, lecture room, etc. (hereinafter referred to as "lecture room"), including a meeting room of a company or school, etc. A variety of functions such as TVs, VCRs, DVDs, tuners, beam projectors, etc. (hereinafter referred to as "learning systems") can be used to simulate virtual infrared (IR) and radio frequency (RF) remote controls. By allowing the remote control learning to be controlled by using an RF remote control, and relates to a technology for remotely controlling the functions of the learning system installed at a distance that does not reach the infrared control signal of the IR remote control with the learned RF remote control.

Generally, as mentioned above, when connected to a learning system equipped with a beam projector, the learning devices used in seminars, lectures, education, and learning, such as meetings, etc., in companies or schools, are mainly used for beam projectors such as TV, VCR, DVD, A wide variety of devices include PCs and camcorders.

FIG. 1 is a block diagram schematically illustrating a state in which a plurality of learning devices connected to a conventional learning system are remotely controlled using respective independent IR remote controllers.

As already mentioned above, a plurality of learning devices (eg, TV, VCR, DVD, PC, beam projector, etc.) 510-550 used in the learning system 500 are provided.

Infrared IR signal for remotely controlling a plurality of learning devices 510-550 connected to the learning system 500 with independent IR remote controllers 610-650. ) The light receiving units 511-551 are provided on the front surfaces of the learning devices 510-550, respectively.

As such, the control signal output by the operation of the key buttons (not shown) provided in the independent IR remote controllers 610-650 is transmitted in infrared through the IR signal transmitting unit 611-651, and then the The received control signal is received by the IR signal receivers 511-551 provided in the learning devices 510-550, respectively, and adjusts targets for various functions related to learning (for example, volume, channel, Luminance, Contrast, Color, Screen Size, Screen Shift, etc. Various adjustment operations are made.

Of course, by pressing a key button (not shown) integrally provided in the learning devices 510-550, the user directly manipulates the adjustment operation of the various adjustment objects mentioned above.

However, the learning devices 510-550 connected to the learning system 500 are installed in another place (for example, a broadcasting room, a central control room, etc.) far from the classroom where most of the learning is being conducted. There are many cases.

Therefore, the operation of directly operating the function by pressing the key buttons installed in the learning devices 510-550 by directly going to the place where the learning system 500 is installed is very inconvenient. There is a need for a means that can be controlled remotely using a remote control that reaches a control signal over a long distance.

However, conventional IR remote controllers 610-650 outputting general IR signals remotely control the learning system 500 using infrared rays as mentioned above.

The infrared ray is a light having a wavelength in the range of about 0.7 μm to several hundred μm between the visible light and the millimeter wave among electromagnetic waves, and has a disadvantage in that transmittance against various obstacles installed in the surrounding area is very low.

In other words, the IR remote controllers 610-650 are IR remote controllers 610-650 when an obstacle such as a concrete wall exists between the IR remote controllers 610-650 and the place where the learning system 500 is installed. If the learning system 500 does not move to where it is seen, overcoming of spatial limitations, which makes it difficult to control the functions of the learning devices connected to the learning system 600, follows.

In order to compensate for the disadvantages of the IR remote controllers (610-650), RF remote control using a radio frequency (RF) is widely used.

As the frequency of the RF signal transmitted from the above-mentioned RF remote control, radio waves in the range of about several hundred megahertz (MHz) are used.

Therefore, the use of the RF remote control has the advantage of overcoming the permeability to obstacles by using the RF signal even at a distance of about 30 to 50m.

However, the RF remote control, unlike the IR remote control has a disadvantage that the remote control can not perform the remote control learning for the various functions provided in the plurality of learning devices (510-550) connected to the learning system 500 Another problem is that it is occurring.
