all three set to the same value:

implies a fixed rate bitstream

only nominal set:

implies a VBR stream that averages the nominal bitrate. No hard

upper/lower limit

upper and or lower set:

implies a VBR bitstream that obeys the bitrate limits. nominal

none set:

the coder does not care to speculate.
