CD-i Ready
CD-i Ready is a compact disc format for mixing audio and data content on a CD. It was developed by Phillips in 1991, based on the CD-i format.
The CD-i Ready format uses a particular technique to get audio CD players to skip over the CD-i software and data. CD-i Ready places the software and data in the pregap of track 1. Since most CD players assume that the pregap area contains only silence, they skip it. Because of this, CD-i Ready was presented as an alternative to CD-i, which was more compatible with audio CD players.
The term "enhanced CD" is sometimes used to refer to different CD formats that support a mix of audio and data content. Apart from CD-i Ready and CD-i, these formats include mixed mode CDs and the Enhanced Music CD format.
