656 ******************************************************************************
657 * @brief  Scale Table for inverse quantizing 8x8 subblock. To inverse quantize
658 * a given 8x8 quantized block, the coefficient at index location (i,j) is scaled
659 * by one of the constants in this table and right shift the result by abs (4 -
660 * floor(qp/6)), here qp is the quantization parameter used to quantize the mb.
661 *
662 * input   : qp%6, index location (i,j)
663 * output  : scale constant.
664 *
665 * @remarks 64 constants for each index position of the subblock and 6 for each
666 * qp%6 in the range 0-5 inclusive.
