707	Mismatch on context index derivation of transform_skip_flag and mts_idx between WD and SW	tsukuba.takeshi		"According to JVET-P2001vD,context index derivation of transform_skip_flag and mts_idx are defined as below:

||               ||||||||||||= binIdx =||
||= syntax element =||= 0 =||= 1 =||= 2 =||= 3 =||= 4 =||= >=5 =|| 
||transform_skip_flag[][][cIdx]|| cIdx==0 ? 0:1 || na || na || na || na || na ||
||mts_idx||  0 || 1 || 2 || 3 || na || na ||

However, in VTM-7.0, context index derivation of transform_skip_flag and mts_idx are defined as below:
||               ||||||||||||= binIdx =||
||= syntax element =||= 0 =||= 1 =||= 2 =||= 3 =||= 4 =||= >=5 =|| 
||transform_skip_flag[][][cIdx]|| cIdx==0 ? 6:11 || na || na || na || na || na ||
||mts_idx||  0 || 7 || 8 || 9 || na || na ||

In addition, unused context indexes (ctxInc = 1 to 5) exist, which should be removed.

Context index derivation in SW should be aligned with WD."	enhancement	closed	minor	VTM-7.1	VTM	VTM-7.0	fixed		ksuehring XiangLi fbossen jvet@…
