Purpose and Scope of Standard
(This section is informative.)
This standard establishes specifications for digital talking books (DTBs) for blind, visually impaired, physically handicapped, learning-disabled, or otherwise print-disabled readers. Its purpose is to ensure interoperability across service organizations and vendors providing content and playback systems to the target population.
This standard provides specifications primarily for DTB files and their interrelationships. It also includes specifications for DTB playback devices in two areas: player performance related to file requirements and player behavior in areas defined in user requirements.
