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

The present invention below supports audio / video signals input from a player executing a recording medium storing education information through an antenna, and receives the transmitted signals and outputs them to a separate speaker. Although it will be described as a preferred embodiment of the video education system using a transmitter to support the distance learning to be carried out, the technical idea of the present invention is not limited or limited to this can be variously modified by those skilled in the art.

1 is a block diagram for explaining the overall configuration of the video education system using the transmitter according to the present invention, Figure 2 is a block diagram for explaining the configuration of the transmitter applied to FIG.

First, referring to FIG. 1, when an audio / video signal is input through a player 10 that reproduces a recording medium storing education information, a video education system using a transmitter may determine whether there is a pilot signal among the input signals. If it is determined whether there is a pilot signal, the corresponding audio signal is transmitted to the outside through an antenna, and the received signal is supported to be output to a speaker, and if there is no pilot signal, it is input from the player 10. The amplified signal is amplified and output to the TV 40.

At this time, preferably, the separate speaker and receiver are to be embedded in a product that can cause children's interest, such as dolls or toys.

The video education system using the transmitter includes a player 10, a transmitter 20, a receiver 30, and a TV 40.

The transmitter 20 receives an audio / video signal through a player 10 that executes a recording medium (for example, a tape or a CD) in which education information is stored, and whether there is a pilot signal among the received signals. If the pilot signal is present, the corresponding audio signal is transmitted to the receiver 30 through the antenna 50, and if not, the corresponding audio / video signal is output through the TV 40 or the PC (not shown). do.

For example, when the student-side voice signal is included in the education information, the pilot signal is provided, and when the teacher-side voice signal is included, the pilot signal is not provided.

The pilot signal has a waveform of several kHz so that it is distinguished from a normal audio signal.

2, the input unit 21 receives an audio / video signal from a player 10 that executes a recording medium having education information stored therein.

Then, the first amplifier 22 amplifies the audio / video signal input through the input unit 21 to a predetermined size and outputs it to the processor 23.

The processor 23 determines whether there is a pilot signal among the signals output from the first amplifier 22. As a result of the determination, if there is a pilot signal, an audio signal of the output signal is output to the modulator 24, and if there is no pilot signal, the output audio / video signal is output to the second amplifier 26.

The second amplifier 26 amplifies the audio / video signal output through the processing unit 23 to a predetermined size and outputs it to the first output unit 27.

Then, the first output unit 27 transmits the audio / video signal output through the second amplifier 26 to the TV 40 or the PC to display the corresponding education information.

Meanwhile, the modulator 24 modulates the audio signal output through the processor 23 and outputs the modulated audio signal to the RF transmitter 25.

Thereafter, the RF transmitter 25 transmits a radio wave corresponding to the modulated signal output from the modulator 24 to the outside through the antenna 50.

3 is a block diagram illustrating a configuration of a receiver applied to FIG. 1.

The receiver 30 supports the audio signal output from the transmitter 20 through the antenna 50 to be output to the speaker 35.

The receiver 30 includes an RF receiver 31, a demodulator 32, a third amplifier 32 and a second output 34.

The RF receiver 31 receives a signal transmitted through the antenna 50. Then, the demodulator 32 demodulates the signal received by the RF receiver 31.

On the other hand, the third amplifier 33 receives the signal applied from the demodulator 32 and amplifies the signal to a predetermined magnitude and outputs it to the second output unit 34.

The second output unit 34 supports the signal output through the third amplifier 33 to be output to the speaker 35.

The receiver 10 and the speaker 35 may be mounted on a product that may cause interest of a child, such as a doll or a character.

The video education system using the transmitter can contain a large amount of learning contents stored in the recording medium (for example, tape or CD), can reproduce various contents such as text, voice, video, etc. in real time, The student side reproduces the recording medium storing the same learning contents at the same time, so that the student side voice signal can be output through the receiver (ie, doll or character), and the teacher side voice signal through the TV 40 or the PC. Support output.

First, the input unit 21 receives an audio / video signal from a player 10 which reproduces a recording medium storing education information (S100).

The first amplifier 22 amplifies the input signal to a predetermined size (S102), and outputs the amplified signal to the processor 23.

Then, the processor 23 determines whether there is a pilot signal among the signals output from the first amplifier 22 (S104).

As a result of the determination of S104, when there is a pilot signal among the signals output from the first amplifier 22, the audio signal output through the processor 23 is modulated (S105) and output to the RF transmitter 25.

Thereafter, the RF transmitter 25 transmits a radio wave corresponding to the modulated signal output from the modulator 24 to the outside through the antenna 50 (S106).

As a result of the determination in S104, when there is no pilot signal among the signals output from the first amplifier 22, the audio / video signal output through the processor 23 is output to the second amplifier 26.

The second amplifier 26 amplifies the audio / video signal output through the processor 23 to a predetermined size (S107) and outputs the same to the first output unit 27.

Then, the first output unit 27 transmits the audio / video signal output through the second amplifier 26 to the TV 40 or the PC so that the corresponding education information is output (S108).

FIG. 5 is a flowchart illustrating an operation of the receiver of FIG. 3.

First, the RF receiver 31 determines whether a signal transmitted through the antenna 50 is received from the transmitter 20 (S200).

As a result of the determination of S200, when the signal transmitted from the transmitter 20 through the antenna 50 is not received, the standby state is maintained for a predetermined time.

As a result of the determination of S200, when a signal transmitted through the antenna 50 is received from the transmitter 20, the demodulator 32 demodulates the signal received by the RF receiver 31 into an original signal. (S201).

On the other hand, the third amplifier 33 receives the signal applied from the demodulator 32 and amplifies it to a predetermined size (S202) and then outputs it to the second output unit 34.

The second output unit 34 supports the signal output through the third amplifier 33 to be output to the speaker 35 (S203).

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention defined in the appended claims.

As described above, the present invention not only provides educational information on TV but also outputs data input from the player to the speaker (student's voice signal) and TV (teacher's voice signal) of the receiver, so that the children receive the receiver. By recognizing the speaker as their friend, it has the effect of inducing their children's interest in learning education.

In addition, when the receiver is mounted on a doll or a character and positioned at a predetermined distance from the transmitter, there is an effect that the education can be freely learned from anywhere.
