If you’ve ever been to a karaoke night, you might have noticed that the KJ has the available songs on a selection of CDs, each of which is usually listed in a catalogue. While more and more Karaoke Jockeys are moving towards storing their tracks on laptop hard drives, the CD format is still popular.
These aren’t standard CDs, however – instead, they use the CD+G format, which stands for compact disc + graphics. Using a portion of the disc that is unused by audio, the CD+G format stores graphic information, such as the song title, background images and the all-important song lyrics.
CD+G has been around for years - the Philips CD-i, the 3DO Interactive Multiplayer, the Amiga CD32 and the Commodore CDTV were all designed to play discs in this format back in the early 1990s.
