Re: [EXTERNAL] [PNG] Meeting minutes - Nov 14th, 2022

Wouldn’t the W3C need to reissue the patent exception request based on the updated document, since we are introducing NEW technical material based on ADDITIONAL existing standards from other bodies with different IP policies?

Great.  If you can get me the “base chunk”, I can add the rest.

Table 10, 11 can identify the necessary info:

The 3rd Edition of the PNG spec is already in the waiting period for its patent exemption period, so I think we can add this metadata without pushing back the shipping date. We would otherwise be mostly sitting idle. So we might as well add it during this down time.

I think you mentioned NBCUniversal might want this metadata for SDR in addition to HDR?

I'll read through CTA-861-G. I haven't yet.
ST 2086 and CEA-861 (not CTA) seemed to use different units. Maybe CTA normalizes them? I'll check.

Hi Everyone,

NBCUniversal would like to see ST.2086, MaxCLL, MaxFALL.  I would recommend this be an amendment on not a requirement for the current draft as CICP is the most important signaling needed ASAP and we would prefer this not be delayed.

The Executive Summary may need a little clarification as ST 2086, MaxCLL, MaxFall are all part of CTA-861-G (I think this is correct 😊)

Attached is a PDF of the meeting minutes from Nov 14th, 2022.

Executive summary:

  *   Two new chunks will be added for ST.2086 and CTA-861-G HDR metadata.
  *   These standards use different units (0.00002 nits, 1 nit) represented in different ways from existing PNG chunks. That is okay. Each chunk will use the units and representations of that standard.
The next meeting will be Nov 28th, 2022.
A future email will list topics for that meeting.
