Latest H.273 is not free #428
Comments
This page says H.273 2021 is superseded and the 2023 version is "in force". I have found a description of the changes between 2021 and 2023, which does not seem it impacts PNG as it is solely for non-RGB formats:
|
Superseded and in-force but not available to general public yet without a TIES login. I’m not sure when it will be fully released (pre-published).

(whoops) |
In today's meeting, we discussed this. Our understanding is that there is a short window where it is not free because a new edition is being released. But it is still generally free. So I'm closing this issue. |
From the PNG spec, the reference to H.273 points to
https://www.itu.int/rec/T-REC-H.273
From that page, there is a link to H.273 (07/21) which still works and is free. But there is also a link to a new version, H.273 (09/23) which says Document restricted to TIES users [ITU-T].
Does anyone know, is that a temporary situation (that version is described as prepublished,) or is this a new, non-free policy coming into effect?
