Green Book (CD standard) Green Book (CD standard) The "Green Book", formally known as the "CD-i Full Functional Specification", is a CD standard announced in 1986 by Philips and Sony that defines the format for interactive, multimedia compact discs designed for CD-i players. The standard was originally not freely available and had to be licensed from Philips. However, the 1994 version of the standard was eventually made available free by Philips. CD-i discs conform to the "Red Book" specification of audio CDs (CD-DA). Tracks on a CD-i's program area can be CD-DA tracks or CD-i tracks, but the first track must always be a
CD+G format that allows for better graphics, but has very rarely been implemented in releases. Along with dedicated Karaoke machines, other consumer devices that play CD+G format CDs include the NEC TurboGrafx-CD (a CD-ROM peripheral for the TurboGrafx-16) and Turbo Duo, the Philips CD-i, the Sega CD, Sega Saturn, the JVC X'Eye, the 3DO Interactive Multiplayer, the Amiga CD32 and Commodore CDTV, and the Atari Jaguar CD (an attachment for the Atari Jaguar). Some CD-ROM drives can also read this data. Pioneer's LaserActive player can also play CD+G discs, as long as either the PAC-S1/S-10 or PAC-N1/N10 game modules are installed.
