This + * presentation may be local to the system containing the presentation, or may + * be via a network or other stream delivery mechanism. + * + * The file structure is object-oriented; a file can be decomposed into + * constituent objects very simply, and the structure of the objects inferred + * directly from their type. The file format is designed to be independent of + * any particular network protocol while enabling efficient support for them in + * general. + * + * The ISO Base Media File Format is a base format for media file formats. + * + * + * An overall view of the normal encapsulation structure is provided in the + * following table. + * + * The table shows those boxes that may occur at the top-level in the left-most + * column; indentation is used to show possible containment. Thus, for example, + * a {@link ISO14496_Box_TKHD Track Header Box} is found in a + * {@link ISO14496_Box_TRAK Track Box}, which is found in a + * {@link ISO14496_Box_MOOV Movie Box}. Not all boxes need be used in all files; + * the mandatory boxes are marked with bold typeface. See the description of the + * individual boxes for a discussion of what must be assumed if the optional + * boxes are not present. + * + * User data objects shall be placed only in {@link ISO14496_Box_MOOV Movie} or + * {@link ISO14496_Box_TRAK Track Boxes}, and objects using an extended type may + * be placed in a wide variety of containers, not just the top level. + * + *
