"QuickTime Concepts
To use QuickTime, you need to understand some concepts that are related to
time-based data: atoms, media structures, components, time management, and
sprites. They are briefly explained in this section.
Atoms
QT atoms are basic containers that QuickTime uses to construct hierarchical
data structures. A newly created QT atom is like the root of a tree. Each
subsequent QT atom is contained in it and contains either data or other
atoms. If a QT atom contains other atoms, it is called a parent atom and the
atoms it contains are called its child atoms. If a QT atom contains data, it
is called a leaf atom. Applications and other kinds of software can also use
the QT atom architecture to store data. For further information about QT
atoms, see "Movie Toolbox: Fundamentals." "
