super cd+g is a new format, similar to the Mp3+g. Basically, it's compressed cd+g files on a dvd-type reading system. It's pretty slow to load up.
I have a definition file on my website that explains most of this... I haven't added the super cd+g yet.

The Cavs Super CD+G player is a dvd mulit-function player.
They also had a jukebox player with a hard drive that could store mp3+g type files.. two seperate players.
For information, you can always go to the CAVS website!
