This should get you started modulo any issues with an older Kshell you may have installed. The script accepts either a decimal SS7 point address in the form of a b c or a decimal value from the command line and computes the alternate form. Hex values are also presented.

Code:
#!/usr/bin/env ksh
case $# in
    1)
        v=$1
        c=$(( $v % 256 ))
        v=$(( $v / 256 ))
        b=$(( $v % 256 ))
        a=$(( ($v / 256) % 256 ))
        printf "%d-%d-%d (%02x-%02x-%02x)\n" $a $b $c $a $b $c
        ;;

    3)  v=$(( (65536*$1) + (256*$2) + $3 ))
        printf "%d  %x\n" $v $v
        ;;

    *)  echo "usage: $0 a b c"
        echo "OR"
        echo "  $0 a"
        exit 1
        ;;
esac
exit

A couple of samples (t16 is my script name):
Code:
spot: t16 190 100 29
12477469  be641d
spot: t16 2 109 20  
158996  26d14
spot: t16 123456  
1-226-64 (01-e2-40)
spot: t16 980321
14-245-97 (0e-f5-61)

Have fun.

mlib_imagecolorrgb2ycc_fp

mlib_ImageColorRGB2YCC_Fp(3MLIB)			    mediaLib Library Functions				  mlib_ImageColorRGB2YCC_Fp(3MLIB)

NAME

       mlib_ImageColorRGB2YCC_Fp - RGB to YCC color conversion

SYNOPSIS

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

       mlib_status mlib_ImageColorRGB2YCC_Fp(mlib_image *dst,
	    const mlib_image *src);

DESCRIPTION

       The mlib_ImageColorRGB2YCC_Fp() function performs a color space conversion from computer R'G'B' to ITU-R Rec.601 Y'CbCr.

       The source and destination images must be three-channel images.

       It uses the following equation:

	 |Y'|	|cmat[0] cmat[1] cmat[2]|   |R'|   |offset[0]|
	 |Cb| = |cmat[3] cmat[4] cmat[5]| * |G'| + |offset[1]|
	 |Cr|	|cmat[6] cmat[7] cmat[8]|   |B'|   |offset[2]|

       where

	 cmat[] = { 65.738/256, 129.057/256,  25.064/256,
		   -37.945/256, -74.494/256, 112.439/256,
		   112.439/256, -94.154/256, -18.285/256 };
	 offset[] = { 16, 128, 128 };
	 src[x][y] = { R', G', B' };
	 dst[x][y] = { Y', Cb, Cr };

PARAMETERS

       The function takes the following arguments:

       dst    Pointer to destination image.

       src    Pointer to source image.

RETURN VALUES

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