Compact Disc Extended Graphics

Compact Disc + Extended Graphics (CD+EG, also known as CD+XG and Extended TV-Graphics) is an improved variant of the Compact Disc + Graphics (CD+G) format. Like CD+G, CD+EG utilizes basic audio CD features to display text and video information in addition to the music being played. This extra data is stored in the subcode channels R-W. Very few, if any, CD+EG discs have been published.
