#492 closed enhancement (fixed)

LFNST index condition in Table 9-82

In Table 9-82 the condition for the first bin of the LFNST index (lfnst_idx[ ][ ]) is given as

( tu_mts_idx[ x0 ][ y0 ]  = =  0  &&  treeType != SINGLE_TREE )  ?  1  :  0

However, as per the adoption JVET-O0368, LFNST is only used if the MTS index is 0. Thus, the first part of the condition is always true and can be omitted.
In the software this check is already omitted (CABACReader.cpp line around 3800).
