hierarchy_embedded_layer_index [MPEG-2 Semantics]
The hierarchy_embedded_layer_index is a 6-bit unsigned integer field in the MPEG-2 hierarchy descriptor that defines the hierarchy table index of the program element that needs to be accessed before decoding of the elementary stream associated with this hierarchy_descriptor. If the hierarchy_type=15 (base layer), this field is undefined.
