399	AMVP spatial scaling candidate in HM-6.0rc1	NaZhang		"As we all know, to remove the dependency of deriving the spatial candidate of upper position on left position, the simplification 2 of JCTVC-G542 defines a new derivation way of the parameter isScaledFlagLX and be adopted in the 7th meeting.

However, in the function ""fillMvpCand"" of the file ""TComDataCU.cpp"" of HM6.0-rc1, before the scaling calculation for upper position, there are two statements:

  bAdded = bAddedSmvp;
  if (pInfo->iN==2) bAdded = true;

In my opinion, the 2nd statement can be deleted, as we only can derive the value of pInfo->iN after checking all the left positions. As a result, we did not really eliminate the dependencies between derivation of the spatial candidate of upper position and left position.

After we carry out this modification, the experiment results is not affected, as the 2nd statement has no substantive role, whereas we really eliminate the dependency."	enhancement	closed	minor	HM-13.0	HM	HM-6.0	fixed		fbossen ksuehring davidf jct-vc@…
