AHG9: New nnpfc_mode_idc for reuse of NNPF definition for new purpose
Authors: Youngkwon Lim
Abstract
An NNPF can be associated with a single purpose and ID within a particular CLVS regardless of its capability. Sometime it might be efficient and useful to reuse NNPF data with new purpose and ID. This contribution propose a new nnpfc_mode_idc for referencing an NNPF already defined with a purpose and ID for new purpose and ID without sending the data again.
Meeting Notes
JVET-AE0279 AHG9: New nnpfc_mode_idc for reuse of NNPF definition for new purpose [Y. Lim (Samsung)] [late]

This was presented in JVET on Friday July 14.

An NNPF can be associated with a single purpose and ID within a particular CLVS regardless of its capability. Sometime it might be efficient and useful to reuse NNPF data with new purpose and ID. This contribution proposes a new nnpfc_mode_idc for referencing an NNPF already defined with a purpose and ID for new purpose and ID without sending the data again.

(This is related to the discussion regarding disallowing changes of purpose, and “purpose” vs. “capability” as per BoG report JVET-AE0172 v2.)

Several experts saw some inconsistency w.r.t. the concept of updating vs. base.

Further study was requested.
