CD-ROM White Book

The White Book, finalised in 1993, defines the VideoCD specification and comprises:

  • Disc format including use of tracks, VideoCD information area, segment play item area, audio/video tracks and CD-DA tracks
  • Data Retrieval Structure, compatible with ISO 9660
  • MPEG audio/video track encoding
  • Segment play item encoding for video sequences, video stills and CD-DA tracks
  • Play sequence descriptors for pre-programmed sequences
  • User data fields for scan data (enabling fast forward/reverse) and closed captions
  • Examples of play sequences and playback control.

With up to 70 minutes of full-motion video storable in specifically encoded MPEG-1 compressed form. White Book is also known as Digital Video (DV). A VideoCD disc contains one data track recorded in CD-ROM XA Mode 2 Form 2. It is always the first track on the disc (Track 1). The ISO 9660 file structure and a CD-i application program are recorded in this track, as well as the VideoCD Information Area which gives general information about the VideoCD disc. After the data track, video is written in one or more subsequent tracks within the same session. These tracks are also recorded in Mode 2 Form 2. The session is closed after all tracks have been written.
