+ * The <i>Sample Table Box</i> contains all the time and data indexing of the
+ * media samples in a track. Using the tables here, it is possible to locate
+ * samples in time, determine their type (e.g. I-frame or not), and determine
+ * their size, container, and offset into that container.
+ *
+ * If the track that contains the Sample Table Box references no data, then the
+ * Sample Table Box does not need to contain any sub-boxes (this is not a very
+ * useful media track).
+ *
+ * If the track that the Sample Table Box is contained in does reference data,
+ * then the following sub-boxes are required: {@link ISO14496_Box_STSD Sample
+ * Description}, {@link ISO14496_Box_STSZ Sample Size},
+ * {@link ISO14496_Box_STSC Sample To Chunk}, and {@link ISO14496_Box_STCO Chunk
+ * Offset}. Further, the {@link ISO14496_Box_STSD Sample Description Box} shall
+ * contain at least one entry. A Sample Description Box is required because it
+ * contains the data reference index field which indicates which
+ * {@link ISO14496_Box_DREF Data Reference Box} to use to retrieve the media
+ * samples. Without the Sample Description, it is not possible to determine
+ * where the media samples are stored. The {@link ISO14496_Box_STSS Sync Sample
+ * Box} is optional. If the Sync Sample Box is not present, all samples are sync
+ * samples.
