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. - * - * <ul> - * <li><b>ftyp</b> -- <i>{@link ISO14496_Box_FTYP File Type Box}</i>;
