Field Documentation

base_eob_cost

int LV_MAP_COEFF_COST::base_eob_cost[4][3]

Cost for encoding the base_eob of a level.

Decoder uses base_eob to derive the base_level as base_eob := base_eob+1.

base_cost

int LV_MAP_COEFF_COST::base_cost[(26+16)][8]

Cost for encoding the base level of a coefficient.

Decoder derives coeff_base as coeff_base := base_eob + 1.

eob_extra_cost

int LV_MAP_COEFF_COST::eob_extra_cost[9][2]

Cost for encoding the last non-zero coefficient.

Eob is derived from eob_extra at the decoder as eob := eob_extra + 1
