| | Types of CDs such as enhanced CDs, CD-ROM, CD-I, Blue book, and orange book |
 | | The basic CD standards and principles are defined in the Red Book (audio), Yellow Book (CD ROM), Orange Book (CD-R), and Green Book (CD-I). |
 | | CD Extra achieves the same as the Yellow Book multisession specification except that it requires special software for premastering and the payment of royalties since it is a Sony/Philips proprietary format. |
 | | CD-I applications vary but include developed titles for education, training, video, games, and other areas of interest where you need to present video, graphics, text and audio to a consumer audience having access to a TV and CD-I player. |
