mlib_VideoIDCT_IEEE_S16_S16(3MLIB)			    mediaLib Library Functions				mlib_VideoIDCT_IEEE_S16_S16(3MLIB)

NAME

       mlib_VideoIDCT_IEEE_S16_S16 - IEEE-1180 compliant inverse Discrete Cosine Transform

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoIDCT_IEEE_S16_S16(mlib_s16 block[64],
	    const mlib_s16 coeffs[64]);

DESCRIPTION

       The mlib_VideoIDCT_IEEE_S16_S16() function computes the inverse DCT (called IDCT) for the output IDCT block of data type mlib_s16 and input
       DCT coefficients of data type mlib_s16. This function is guaranteed to be IEEE-1180 -compliant. The output of the IDCT routine is the  dif-
       ference	between the current block and the reference block. The difference pixel can occupy nine bits and is represented as a 16-bit datum.
       The output must be added to the motion-compensated reference block in order to reconstruct the current block.

PARAMETERS

       The function takes the following arguments:

       block	 Pointer to an 8x8 motion-compensated block that is the difference between the reference block and the current block.  block  need
		 not be 8-byte aligned.

       coeffs	 Pointer to the source DCT coefficients. coeffs need not be 8-byte aligned.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

ATTRIBUTES
