KR960002319A - Video flexible media on which chord signals are recorded and playback equipment thereof - Google Patents

Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image flexible medium on which a chord signal is recorded and to a playback apparatus thereof, wherein the image flexible medium records a chord signal in one of a plurality of channels in which an audio signal is recorded, and records the audio signal in another channel. It is possible to generate a chord for the chord, and the chord signal includes a synchronization signal, a key control signal, and a chord signal, and the apparatus for reproducing the video flexible medium is capable of generating chords for the audio signal. Audio signal processing means (10) for acquiring accompaniment and chord signals by analog processing a signal reproduced from a flexible medium, and chord signal extracting means (15) for low-pass filtering the chord signal to a predetermined frequency band; 16), chord processing control means 17 for processing a chord signal extracted from the chord signal extracting means 15 and 16 to provide a chord control signal, and the chord processing agent Harmonic generating means 24 for producing a chord for a voice signal input from the voice input device in accordance with the chord control signal provided by the means 17, which is useful for the chord processing control means 17 and the chord generating means 24. A timer means 23 for generating and outputting a timing signal, and mixing means for mixing and outputting the chord generated by the chord generating means 24 and the voice signal from the voice input device. It is to generate a chord signal for the voice signal.
