The Sample Group Description Box table gives information about the characteristics of sample groups. The descriptive information is any other information needed to define or characterize the 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 Group Description 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 To Group shall indicate the same value for the grouping type.
