| 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. |
