[M4IF Technotes] dquant in macroblock header

[Ramkishor Korada]

Hi,
 Quantizer scale gets updated as and when dquant is found in the macroblock
header and if there is no update then the existing quantizer scale is used.
So, dquant affects the quantizer step for the remaining macroblocks in the
VOP.
