3. Introduction to DAISY.
This chapter gives an overview of the DAISY format and some of the
terminology used. If you are new to the DAISY format, you should read
this chapter thoroughly. If you are an experienced DAISY user, you may
wish to skim read the chapter or bypass it altogether.
3.1. What is DAISY?
DAISY is an acronym which stands for Digital Accessible Information
System. It is the format which is being developed as the international
standard for digital talking books. DAISY books can be played on a
dedicated hardware player or on a computer equipped with the
appropriate software.
3.2. Main features of DAISY.
The main features of the DAISY format are as follows:
• Compression of information - with high levels of compression
available, it is possible to store up to 90 hours of digital audio on a
single CD.
• Flexible Navigation - the DAISY format includes a range of features
which enable the reader to quickly access the parts of the book
they wish to read. These features include navigation on 6 levels, by
pages, by groups and phrases. These items will be discussed in
more detail later in this chapter.
• Multi-media capability - in addition to digital audio, the DAISY
format is able to incorporate text, graphics and even video to
provide the reader with a fully synchronized, multi-media reading
experience.
