These are some of the Karaoke formats available and a brief description of what they are.

	CD - The standard audio CD. Standard audio CD's store audio only. Karaoke discs of this type do not display lyrics.
	CD+G - The most popular "non-computer" Karaoke format. Used by professional DJ's and KJ's. These are standard audio CD's with additional graphics commands in the normally unused "subcode" area. Graphics are interpreted by the player as the audio is played to display and highlight the lyrics or display simple logos or images.
	VideoCD - Also known as VCD or Digital Video Disc. A popular form of Karaoke in Japan. VCD's are similar to CD-ROM discs and contain a file system in which each track is a file. VCD's use MPEG video and audio to display lyrics on top of a video picture.
	MIDI - A standard format used by many musical instruments and devices. The most popular computer Karaoke format. Midi files contain events like note on or off but does not actually store the sound of the note. The playback device generates the music. Karaoke MIDI files use Text events to synchronize the lyrics to the music.
	MP3+G - The "new" PC Karaoke standard created by TriceraSoft. MP3+G files are converted from a standard CD+G disc to a PC friendly format. The audio is compressed using the very popular MP3 format to save space.
	WMA+G - The alternate PC Karaoke standard created by TriceraSoft. WMA+G files are similar to MP3+G, although can save further space by using the audio WMA format.
	MP3+G Zipped - An extension of the MP3+G format by compressing the MP3+G file pair into a zip. An Application or Player must decompress the files before using them.
	KMF with MP3+G inside - A secure or shareable one file format invented by TriceraSoft. The MP3+G (as above) two separate files are combined into one file, and the graphics data is further compressed to save even more space. KMF files have additional security features.
	KMF with WMA+G - As above but using the Windows Media Audio format that can be almost half the size of the equivilent MP3 file for even more space savings.
	DVD - The new Video Disc Standard. Like VCD but much higher capacity and higher quality using MPEG2 video. Requires a special Software DVD player and/or Hardware decoder to play on a PC.
	LaserDisc - Analog 12" Video disc. The first "high quality" video disc format. LaserDisc plays broadcast quality video and audio and became popular for movies and later Karaoke but failed due to thier high cost and large size. Replaced by DVD. Not playable on the computer.
