The White Book also defines the more general CD-i Bridge format (also called CD-Bridge or simply "bridge discs"), which are CD-ROM XA

discs with an additional Green Book CD-i specific application program. The CD-ROM XA information in bridge discs can be obtained through CD-ROM drives, while CD-i players can use the CD-i program to read bridge discs as well (hence the "bridge" status between CD-ROMs and CD-i discs). Bridge discs must conform to both the CD-ROM XA and Green Book CD-i specifications. VCDs and SVCDs fall under the category of bridge discs, as do Photo CDs and Karaoke CD
