Abstract
Video-song media having chord data recorded thereon and playback system thereof for reproducing the chord responsive to a singer's singing voice are disclosed. The video-song media having chord data recorded thereon has the chord data which is additionally recorded in a sub-code of the program area having video-song information therein. The playback system for the video-song media having chord data recorded thereon, reproduces word data to the song, the accompaniment music and the graphic signal relating to a corresponding music, and also reproduces the chord specified by chord data in response to the voice input signal provided by a voice input device. Accordingly, sound effects can be maximized in order to multiply the user's interest while practicing singing the video-song.
Claims7
A playback system for a video-song medium having chord data recorded thereon, comprising:
- an audio/video readout means for reading out an accompaniment music signal, word data to a song, and a chord data signal from video-song medium on which the word data to the song, the accompaniment music signal, and graphic information are respectively recorded in a program area and chord control data is additionally recorded in a plurality of channels relating to graphic information in a sub-code, and outputting a readout audio signal;
- a digital signal processing section means for extracting and processing an accompaniment music signal and a chord data signal in response to the readout audio signal provided by the audio/video readout means, and outputting an accompaniment music signal and a chord data signal which has synchronous signals and chord control data;
- an accompaniment music processing means for reproducing an audible accompaniment music signal in response to the accompaniment music signal provided by the digital signal processing section means, and outputting a first buffer signal;
- a voice input signal processing means for processing a voice input signal corresponding to a singer's singing voice provided by a voice input device, and outputting a second buffer signal;
- a chord generation means for producing a chord signal in response to the chord data and the second buffer signal respectively provided by the digital signal processing section means and the voice input signal processing means, and outputting a chord processing circuitry signal;
- an output pre-processing means for multiplexing and processing the second buffer signal and the chord processing circuitry signal respectively provided by the voice input signal processing means and chord generation means in order to be suitable for data outputting, and outputting an audio amplifier signal;
- and
- an audio output means for converting into audible signals the audio amplifier signal and the first buffer signal respectively provided by the output pre-processing means and the accompaniment music processing means.
