NAME
     mlibVideoDeQuantizeInitS16  -  dequantization  of  forward
     Discrete Cosine Transform (DCT) coefficients

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     mlibstatus mlibVideoDeQuantizeInitS16(mlibd64 dqtable[64],
          const mlibs16 iqtable[64]);


DESCRIPTION
     The mlibVideoDeQuantizeInitS16() function initializes  the
     dequantization table.


     The following equation is used:

       dqtable[i] = iqtable[i];  0 < i < 64


PARAMETERS
     The function takes the following arguments:

     dqtable    Pointer to dequantizer table coefficients.


     iqtable    Pointer to original quantizer table coefficients:

                  0 < iqtable[i] < 128



RETURN VALUES
     The function returns MLIBSUCES if  successful.  Otherwise
     it returns MLIBFAILURE.
