Z3986 Requirements Detail

Provide better support for complex content containing tens of thousands of entries that when produced as DAISY material translates to levels. In the DAISY current standard, having tens of thousands of levels makes content very resource-demanding for reading systems. Often, playback is virtually impossible because of the size of the syncronization and navigation data structures.

Users are requesting access to complex material such as dictionaries, encyclopedia, reference material and TV guides. Such material often contains a very large number of entries that when produced as DAISY translates to levels.
