JVET-AE0298 AHG9: Combined text of JVET-AE0052 and JVET-AE0063 [M. M. Hannuksela, F. Cricri (Nokia), L. Chen, O. Chubach, Y.-W. Huang, S. Lei (MediaTek)] [late]

This document contains a combination of JVET-AE0052 and JVET-AE0063 for potential inclusion to Technologies under Consideration for VSEI.

The NNPF group design in this section contains the following aspects:

NNPF group characteristics (NNPFGC) SEI message, which can be used to define any of the following:

1. a cascade of NNPFs
2. a group of NNPFs which are activated in an alternating manner so that at most one of these NNPFs is activated by NNPFA SEI messages for any picture unit
3. a set of alternative NNPFs or alternative NNPF groups out of which only one is to be selected in the decoder side
4. a set of NNPFs or NNPF groups intended to be applied in parallel
5. NNPFs or NNPFs groups that are optional

NNPF group activation (NNPFGA) SEI message, which is used for activating an NNPF group.

Extension of the NNPFA SEI message semantics so that it can activate an NNPF group

An update of the general post-processing filtering process using NNPFs to take into account the proposed NNPFGC and NNPFGA SEI messages.

The combined text was presented in JVET Tuesday 18 July 1145.

The text contains a concept where the existing NNPFA SEI can be used to activate a group. It was asked whether a separate group activation SEI message also included in the text is needed at all. This is left for further study.

Decision: Adopt JVET-AE0298 into JVET-AE2032 TuC.
