JCTVC-J0577 Proposal to support UHDTV colorimetry [T. Suzuki (Sony)]

J0577

TBA.This contribution proposed adding UHDTV colorimetry support in HEVC.

Decision: Adopted, but using two values for the additional transfer_characteristics entries to distinguish the nominally 10 and 12 bit cases.

This contribution proposed adding UHDTV colorimetry support in HEVC.

Others

3 other NBs had provided relevant remarks, summarized roughly below.

25721 France HEVC

- non-4:2:0

- 10 b and beyond

- extended gamut

- as soon as feasible, e.g. Jan 2014

- related J0078 / M25400 and J0079 / M25401

- Consider interlace in Main

- consider tool usage and constraints when defining levels

- related document is 25586 and ???

- WPP is good, tiles are badless desirable; suggesting to remove tiles from Main

- listing various contributions
25348 HEVC US

- two tiers advocated, with level nesting within each tier

- syntax should not limit tool combinations esp. tiles & WPP

- start code emulation prevention should be required in all environments

25940 Korea

- consider whether both tiles & wavefronts needed

- be conservative about adding new tools into Main profile

- consider adopting new tools to improve subjective quality of chroma
