+ * sample belongs to and the associated description of that sample group. The
+ * table is compactly coded with each entry giving the index of the first sample
+ * of a run of samples with the same sample group descriptor. The sample group
+ * description ID is an index that refers to a {@link ISO14496_Box_SGPD Sample
+ * Group Description Box}, which contains entries describing the characteristics
+ * of each sample group.
+ * 
+ * There may be multiple instances of this box if there is more than one sample
+ * grouping for the samples in a track. Each instance of the Sample To Group Box
+ * has a type code that distinguishes different sample groupings. Within a
+ * track, there shall be at most one instance of this box with a particular
+ * grouping type. The associated Sample Group Description shall indicate the
+ * same value for the grouping type.
