ABSTRACT:
A CD video-song accompaniment apparatus reproduces information from a compact disc and contains a CD reproducing portion, a CD-OK reproducing portion, and audio selector, and a main controller. The CD reproducing portion reads audio data from the compact disc and generates an audio signal if the compact disc is a first type of compact disc. On the other hand, the CD reproducing portion reads digital data from the compact disc if the compact disc is a second type of compact disc. The CD-OK reproducing portion inputs the digital data, which contains background image data and music information data, generates a first background image and a second background image based on the background image data, and generates a CD-OK audio signal based on the music information data. The audio selector inputs the audio signal generated by the CD reproducing portion and the CD-OK audio signal generated by the CD-OK reproducing portion and selectively outputs either the audio signal or the CD-OK audio signal. The main controller determines whether the compact disc is the first type of compact disc or the second type of compact disc. Subsequently, the main controller instructs the audio selector to output the audio signal if the compact disc is the first type of compact disc and instructs the audio selector to output the CD-OK audio signal if the compact disc is the second type of compact disc.
