| 49 | * @brief In cavlc encoding, a lut is used for encoding levels. It is not possible |
| 50 | * to use look up for all possible levels. The extent to which look up is generated |
| 51 | * is based on the statistics that were collected in the following global variables. |
| 52 | * |
| 53 | * gu4_cavlc_level_bin_lt_4 represents the number coefficients with abs(level) < 4 |
| 54 | * gu4_cavlc_level_bin_lt_16 represents the number coefficients with 4 < abs(level) < 16 |
| 55 | * gu4_cavlc_level_bin_lt_32 represents the number coefficients with 16 < abs(level) < 32 |
| 56 | * and so on ... |
