Edit Box maps the presentation time-line to the media time-line as * it is stored in the file. The Edit Box is a container for the edit lists. * * The Edit Box is optional. In the absence of this box, there is an implicit * one-to-one mapping of these time-lines, and the presentation of a track * starts at the beginning of the presentation. An empty edit is used to offset * the start time of a track. * * @category Zend * @package Zend_Media * @subpackage ISO 14496 * @author Sven Vollbehr * @copyright Copyright (c) 2005-2009 Zend Technologies USA Inc.
