[Mp4-tech] [H.264]about the scaled versions of the motion vector in the 8.4.1.2.3 section

[Tan Rui -- Huawei]

Hi, All experts,
I want to ask a question about the calculation about the scaled versions of the motion vector in the 8.4.1.2.3 section.
I read lots of papers give the following equations:
mVL0 = (tb / td) * mvCol
mVL1 = ((tb - td) / td) * mvCol
But in the protocol 8.4.1.2.3 section, from the (8-194) equation to the (8-199) equation, there is a DistScaleFactor 
variable. I can not calculate those equations from the above equations which were found the papers. Can
some one provide some information about it? I spent some time to search the detail description, but I can not
get any useful explanations.
