KR970008029A - Digital song accompaniment system using MPEG-CDV - Google Patents

Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital song accompaniment system using MPEG-CDV, in which image data is not provided from the outside or a switch key in a key input unit is switched to an MPEG-V state by a user's operation. When the user selects a desired song, the video data corresponding to the genre of the song selected by the user is selected from MPEG-CDV based on the control signal for selection from the microcomputer, and the sound source data of the song selected by the user is selected. The lyrics data from the sound source storage medium is provided to the image processing unit during the sound source data, and the sound data of the sound source data is converted into an analog signal and then provided to the mixer. Then, the video data selected from MPEG-CDV and the lyrics data provided through the microcomputer are signal-processed by the video processor, and then converted into analog signals. The video data selected from the MPEG-CDV is displayed as a background image on the monitor, and the microcomputer The provided lyrics data are OSD processed and displayed as a subtitle on the monitor, while the sound data among the sound source data provided through the microcomputer are mixed by the user voice data input through the microphone and the mixer and then output through the speaker. The selected song selectively displays a group of video data stored in MPEG-CDV according to genre, so that the background image of the song can be displayed more adaptively, and the user can be provided with more realism. .

Digital song accompaniment system using MPEG-CDV

Since this is an open matter, no full text was included.

1 is a schematic block diagram of a digital song accompaniment system using MPEG-CDV according to a preferred embodiment of the present invention.

Claims (1)

In a digital song accompaniment system that outputs image data and sound data of a song selected by a user, when a key for curve tack is input by a user's operation, a corresponding key signal is generated, and the external image and the MPEG DVD state are displayed. Key input means (110) having a switching key for switching the power supply; A sound source storage medium 120 for storing respective sound source data for a plurality of songs; An image storage medium 140 that is set according to the genre of each song stored in the sound source storage medium 120 and stores a group of image data corresponding to the genres; The sound source data corresponding to the key signal for the curved tack generated from the key input unit 110 is extracted from the sound source storage medium 120, and the lyrics data is converted into the image processing means 150, and the acoustic data is converted into an analog signal. And then to each of the mixing means 160, the control signal for selecting the image data corresponding to the genre of the song selected by the user when the image data is not provided from the outside or the conversion key is in the MPEG-D state A microcomputer 130 generated by an image storage medium; The image data selected from the image storage medium 140 and the lyrics data provided through the microcomputer 130 are signal-processed and then converted into analog signals to monitor the image data selected from the image storage medium 140 as a background image. The image processing means (150) for displaying the video data and the lyrics data provided through the microcomputer (130) for OSD processing and then displaying the lyrics data as subtitles; MPEG-DV (MPEG-) characterized in that the mixing means 160 for mixing the sound signal data provided through the microphone and the user's voice data input through the microphone and then output to the speaker Song accompaniment system using CDV). ※ Note: The disclosure is based on the initial application.
