JVET-D0168 EE1: NSST-PDPC Harmonization [S.-H. Kim, M. Kiran, A. Segall (Sharp)] [late]
This contribution provides information on EE1 investigation on independent application of non-separable secondary transform (NSST) and position dependent intra prediction coding (PDPC). Note, the current JEM3.0 has separate coding tree between luma and chroma for intra slices; and dependent application of NSST based on PDPC flag exists only for the luma component. It is reported that decoupling PDPC and NSST for luma provides 0.15% luma BD bit rate saving while having increment of encoding time by 60%.
It was reported that, regarding PDPC/NSST combination, due to the QTBT adoption of last meeting, the issue was resolved, and no further action was necessary.
