According to the above configuration, the operation of the portable image flexible half-cycle using the video compact disc according to the embodiment of the present invention is as follows.

First, when power is applied, the half-cycle operation of the wired / wireless combined image flexible half cycle using the video compact disc according to the embodiment of the present invention is started.

After the operation is started, the user selects either the compact disc mode or the computer mode using the control buttons installed in the key input unit 10 or the wireless microphone 140 installed on the front panel of the main body. Then, if a play command is input after selecting a song, the system control unit 20 controls the VCD control unit 40 or the PLC / FPGA control unit 50 accordingly, thereby controlling the VCD control unit 40 or the PLC / FPGA control unit ( 50) allows the video, subtitles, accompaniment music, and audio to be output from the main body.

In this case, the command signal input to the wireless microphone 140 through the control button is demodulated through the voice transmitting and receiving antenna 130 and the control signal detection demodulation unit 160 and then input to the system control unit 20.

In addition, the system control unit 20 generates and outputs data such that a main command among the control commands input from the key input unit 10 or the wireless microphone 140 can be displayed on the screen (OSD). .

If the compact disc mode is set, the system controller 20 controls the path of the switch SW so that the voice signal input from the wired microphone is connected to the switch SW and the voice detector 30. Or the audio signal input from the wireless microphone 140 is transmitted to the VCD control unit 40 via the voice transmitting / receiving antenna 130, the voice FM receiving demodulator 150, and the switching switch 30. To be printed).

The VCD controller 40 reproduces the video and subtitle signals stored in the compact disc under the control of the system controller 20 and outputs them to the video selector 60, and at the same time the accompaniment stored in the compact disc. The voice signal input from the voice detector 30 together with the music signal is output to the audio selector 70.

The operation of the VCD control unit 40 will be described in more detail for each part with reference to the attached FIG. 2 as follows.

When the control signal is input from the system control unit 20, the MPEG controller 41 outputs the control signal to the CDP controller 42 so that the video, subtitles, and accompaniment music, which are compressed and stored on the compact disc, are output.

In this case, the CDP controller 42 controls the driver 44 via the high frequency amplification servo 43 to cause the motor of the CDP deck 45 to rotate. As such, when the motor of the deck 45 is rotated on the CDP, the compressed signal (MPEG signal) is output from the compact disc to the MPEG decoder 47 through the pickup, the high frequency amplification servo 43, and the digital signal processor 46. .

The MPEG decoder 47 decodes the compressed signals from the digital signal processing unit 46 in the memory 48 and 49 while decoding them, and outputs the accompaniment music signal to the karaoke controller 4B, and the video and subtitle signals are video. Output to the D / A encoder 4A.

The television RF modulator 90 modulates and outputs the video and subtitle signals input from the video selector 60 and the accompaniment music and audio signals input from the audio selector 70 according to the three or four channels of the television. The accompaniment music and song voices are output together with the video subtitles (not shown).

In addition, the TV wireless transmitter 100 modulates the video and subtitle signals input from the video selector 60 and the accompaniment music and audio signals input from the audio selector 70 into a high frequency signal to convert the transmission antenna 110. Air propagation through allows the accompaniment music and song voices to be output along with video and subtitles from feature channels (not 3 and 4 channels) of televisions (not shown).

In addition, the FM voice transmitter 120 modulates the accompaniment music and voice signals input from the audio selector 70 into FM high frequency signals, thereby air propagating through the voice transmission / reception antenna 130 (not shown). Accompaniment music and song voices are output from a specific frequency band.

In addition, when an external device (not shown) is connected to the line voice output signal line and the line image output signal line, accompaniment music and song sound may be output together with the image and the subtitle. In this case, when the user records on the screen using a camera and connects the video tape recorder as the external device, the user records the recording tape repeatedly by recording a voice along with his singing. You can practice your singing effectively because you can fully review your attitude, pitch, beat, and emotion.

The display unit 170 displays the operation state of the image flexible half cycle according to control signals and data signals input from the system control unit 160, the VCD control unit 40, and the PLC control unit 50.
