The auxiliary memory device 421 stores an accompaniment tune for a song and an image supporting the same, and the output is controlled by the controller 410 and supports a caption processing function in accordance with the accompaniment procedure.

The decoder 422 decodes encoded digital data, and performs a function of decoding digital data carrying an accompaniment tune stored in the auxiliary memory device 421.

The digital-to-analog converter (D.A.C) 423 converts discrete digital data into continuous analog data, and converts the decoded digital data into analog data through the decoder 422.

The mixer 424 synthesizes a voice input through the microphone 200 and an accompaniment tune converted into analog data through the digital-to-analog converter (DAC) 423, and the amplifier 425. Amplifies the synthesized analog sound so as to output through the speaker 310. However, in the case of regeneration, a separate synthesis process is not necessary.

Meanwhile, the song file generation / reproducing unit 430 includes an analog / digital converter (ADC) 431, a codec 432, a memory 433, a formatter / deformatter 434, and an interface 435. It is composed.

The analog-to-digital converter (ADC) 431 performs a function opposite to that of the digital-to-analog converter (DAC) 423 and converts the analog data synthesized in the mixer 424 into digital data for external storage. .

The codec 432 encodes the digital data converted by the analog-to-digital converter (ADC) 431 in a form in which a coder and a decoder are synthesized, and stores the encoded data in the memory 433 or the digital data stored in the memory 433. Decodes the signal and transmits it to the digital-to-analog converter (DAC) 423. In the present invention, the decoder 422 may be integrated with the decoder.

The memory 433 performs a function of internally storing digital data received from the codec 432 in a storage process and from the formatter / deformatter 434 in a playback process.

The formatter / deformatter 434 formats digital data stored in the memory 433 into a predetermined file format in a storage process, and deformats a file that has already been formatted into an original file in a playback process. In this case, the predetermined file format to be formatted is preferably an MP3 file format or a media file format.

The interface 435 supports connection and transmission of the song half cycle 400 and the external storage device 500, and may be adopted by the type of the external storage device 500.

On the other hand, the controller 410 controls the operation of each component of the song / video output unit 420 and the song file generation / playback unit 430.

Specifically, the control unit 410 receives the storage signal of the keypad 100, and stores the data in the memory 433 by the presence or absence of data received by the analog-to-digital converter (ADC) 431, The data is stored in the storage medium (not shown) by the presence or absence of the external storage device 500 and a storage medium (not shown).

In addition, by receiving the playback signal of the keypad 100, the external storage device 500, the storage medium (not shown) and the data stored in the presence or absence of the stored data to store the data in the memory 433, The digital / analog converter (DAC) 423 performs a function of outputting the data to the outside by the presence or absence of data received.

Next, a process of storing or playing a song using the karaoke apparatus according to the present invention described above will be described in detail with reference to the accompanying drawings.
