Scoring device when the song accompaniment function of the video compact disc player

摘要

The present invention relates to a scoring apparatus in the song accompaniment function of a video compact disc player. To this end, the present invention is a mono / stereo bit constituting the audio coding information bytes of a predetermined disc to be reproduced for the song accompaniment function, the user according to the accompaniment generated from the disc. The data indicating the point at which the song should be sung and the point at which the song should be stopped is pre-recorded, and the microphone 200 for outputting an audio signal generated by a user singing a song when the song accompaniment function is executed through a predetermined process such as amplification is performed. And a comparator 210 for comparing and processing the audio signal provided from the microphone 200 with a preset reference level signal and outputting the digital signal as a digital signal corresponding to '0' or '1', and a digital signal processor. From 60, the spare bit of the mono / stereo bit is read out of the data reproduced from the disc, and the reserved bit signal and the ratio It includes a microcomputer 220, which marks the score by comparing the output signal of unit 210, and configuration.;Therefore, the present invention has the effect of scoring the score for the beat of the song that the user sings in the song accompaniment function by using the spare bits of the mono / stereo information bits constituting the audio coding information byte.
