* The <i>File Type Box</i> is placed as early as possible in the file (e.g.

* boxes such as a {@link Zend_Media_Iso14496_Box_Moov Movie Box},
* {@link Zend_Media_Iso14496_Box_Mdat Media Data Box}, or
* {@link Zend_Media_Iso14496_Box_Free Free Space}). It identifies which
* specification is the <i>best use</i> of the file, and a minor version of
* that specification; and also a set of others specifications to which the
* file complies.
*
* The minor version is informative only. It does not appear for
* compatible-brands, and must not be used to determine the conformance of a
* file to a standard. It may allow more precise identification of the major
* specification, for inspection, debugging, or improved decoding.
*
* The type <i>isom</i> (ISO Base Media file) is defined as identifying files
* that conform to the first version of the ISO Base Media File Format. More
* specific identifiers can be used to identify precise versions of
* specifications providing more detail. This brand is not be used as the major
* brand; this base file format should be derived into another specification to
* be used. There is therefore no defined normal file extension, or mime type
* assigned to this brand, nor definition of the minor version when <i>isom</i>
* is the major brand.
*
* Files would normally be externally identified (e.g. with a file extension or
* mime type) that identifies the <i>best use</i> (major brand), or the brand
* that the author believes will provide the greatest compatibility.
*
* The brand <i>iso2</i> shall be used to indicate compatibility with the
* amended version of the ISO Base Media File Format; it may be used in addition
* to or instead of the <i>isom</i> brand and the same usage rules apply. If
* used without the brand <i>isom</i> identifying the first version of the
* specification, it indicates that support for some or all of the technology
* introduced by the amended version of the ISO Base Media File Format is
* required.
*
* The brand <i>avc1</i> shall be used to indicate that the file is conformant
* with the <i>AVC Extensions</i>. If used without other brands, this implies
* that support for those extensions is required. The use of <i>avc1</i> as a
* major-brand may be permitted by specifications; in that case, that
* specification defines the file extension and required behavior.
*
* If a Meta-box with an MPEG-7 handler type is used at the file level, then the
* brand <i>mp71</i> is a member of the compatible-brands list in the file-type
* box.

/**
* The <i>The Item Location Box</i> provides a directory of resources in this or
* other files, by locating their containing file, their offset within that
* file, and their length. Placing this in binary format enables common handling
* of this data, even by systems which do not understand the particular metadata
* system (handler) used. For example, a system might integrate all the
* externally referenced metadata resources into one file, re-adjusting file
* offsets and file references accordingly.
*
* Items may be stored fragmented into extents, e.g. to enable interleaving. An
* extent is a contiguous subset of the bytes of the resource; the resource is
* formed by concatenating the extents. If only one extent is used then either
* or both of the offset and length may be implied:
*
* o If the offset is not identified (the field has a length of zero), then
* the beginning of the file (offset 0) is implied.
* o If the length is not specified, or specified as zero, then the entire
* file length is implied. References into the same file as this metadata,
* or items divided into more than one extent, should have an explicit
* offset and length, or use a MIME type requiring a different
* interpretation of the file, to avoid infinite recursion.
*
* The size of the item is the sum of the extentLengths. Note: extents may be
* interleaved with the chunks defined by the sample tables of tracks.
*
* The dataReferenceIndex may take the value 0, indicating a reference into the
* same file as this metadata, or an index into the dataReference table.
*
* Some referenced data may itself use offset/length techniques to address
* resources within it (e.g. an MP4 file might be included in this way).
* Normally such offsets are relative to the beginning of the containing file.
* The field base offset provides an additional offset for offset calculations
* within that contained data. For example, if an MP4 file is included within a
* file formatted to this specification, then normally data-offsets within that
* MP4 section are relative to the beginning of file; baseOffset adds to those
* offsets.
