7.1Project development
Finalization revisiting.
Decision: Add the following profile specifications:
-
All intra – yes, bit depths skip 14
-
Monochrome – 12 & 16
-
4:4:4 8b
Not in output draft – for further study:
Decision: Prohibiting TS rotation, TS context, intra BC, RDPCM intra/inter, intra smooth disable, large-block TS in 4:2:0 and 4:2:2 profiles – Agreed (Rice init – No, Chroma QP not 4:2:0 but OK in 4:2:2).
Cross-component color prediction only applies to 4:4:4 (and can be in those profiles).
Otherwise no applicable features prohibited. Further study on tools is planned to confirm.
SDecision: Regarding signalling for new profile constraints – leave editors are requested to use constraint flags as appropriate minimize the number of assined profile_idc valuessignalling tbd.
Also Definition of tiers and levels remains– tbd.
Decision: All intra – no out of order pictures. All pictures must be IRAPs. In-loop filtering optional as in AVC.
High precision weighted prediction – enable for all new >8b profile.
Chroma deblocking – for further study.
The two encapsulation approaches are under consideration for technical study, not yet endorsed as planned supported types. The external systems mux approach is agreed as being planned.
In the RExt software, the high-precision forward transform will be enabled by default when operating in "RExt high bit depth" mode.
