SCC text error of act qp offset addition process in 8.6.1 and 8.6.2.

Description

Act qp offset in JCTVC-T0140 was adopted in the last meeting.

It seems that JCTVC-T1005 v2 contains the following text integration errors:
(1) qPiCb and qPiCr derivations described in (8-278) and (8-279) of 8.6.1 are not modified as in JCTVC-T0140 text.
(2) qP derivations for cIdx=1 and cIdx=2 described in (8-283) and (8-284) of 8.6.2 are not modified as in JCTVC-T0140 text.

As the result, act qp offsets are additionally added to Qp'cb and Qp'cr which are already added with (non-act) qp offsets. Obviously that is not intended operation.

The above parts in 8.6.1 and 8.6.2 should be corrected according to JCTVC-T0140 text.
