Green Book CD-ROM

   A standard CD-ROM format developed by Philips for CD-i.
   It is ISO 9660 compliant and uses mode 2 form 2 addressing.
   It can only be played on drives which are XA (Extended
   Architecture) compatible.

   Many Green Book discs contain CD-i applications which can
   only be played on a CD-i player but many others contain
   films or music videos.  Video CDs in Green Book format are
   normally labelled "Digital Video on CD"

   Green Book was obsoleted by White book CD-ROM in March 1994.
