<p class="MsoNormal"><span style="color:#1F497D">Hello all,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Following up on my AHG new mandates announcement last week – the Working Draft of the future amendment [based on the COLR v1 contribution to the WG] is now available for public review (see attached). Certain
items are highlighted with my editorial notes – these parts would benefit from additional contributions to extend and/or revise the text (as the case may be).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">With the GitHub now available for AHG to use, I suggest that new comments on the working draft text should be filed as issues with “amendment” label attached. Once we have these new issues resolved, we will prepare
and submit the new input contribution(s) to the WG with our recommended revision proposals.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The next WG meeting will be virtual, happening in mid-January, and due to extra time needed to prepare for the virtual meeting and due to end of the year holiday period, the WG decided to impose early deadlines
for registration and submission of new input contributions. Respectively, these deadlines are Dec. 30, 2020 for document registration, and Jan. 4<sup>th</sup>, 2021 for document upload. Please keep this in mind as we have only a couple of months left to discuss
and propose changes.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Any new items (those that are not currently part of the amendment) can also be brought up for discussion, according to the mandate #2. It is possible and quite likely that the working draft amendment document
will remain in the Working Draft stage even after the January WG meeting – I’d like to make sure that we prioritize quality of the spec and content completeness over expediency in finalizing this amendment.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Thank you,<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">P.S. The draft amendment is prepared against the 4<sup>th</sup> edition ISO/IEC 14496-22 document, available for download free of charge from ISO publicly available standards:

<p class="MsoNormal">Based on the contributions submitted to the WG meeting, the WG recommendation was to start a new amendment process for ISO/IEC 14496-22:2019 AMD2, that would give us an opportunity to update COLR table description and introduce other technical
changes. I am very pleased to announce that the WG recognized our desire to use GitHub repo as a new venue for technical discussions – as you can see from the mandate description, this is now explicitly mentioned both in the mandates section and as our new
communication channel. Please keep in mind that the GitHub repo is intended to be used for discussing technical issues only, the administrative matters of the AHG and the discussions related to AHG recommendations will be conducted on the AHG email list. I
also would like to remind you that according to the ISO JTC1 rules, the discussions on the AHG forums should be limited to what is specifically authorized by the current mandates.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As a reminder, the membership in this AHG is open to public and is subject to the rules and principles outlined in the ISO Code of Conduct (<a href="https://www.iso.org/files/live/sites/isoorg/files/store/en/PUB100397.pdf">https://www.iso.org/files/live/sites/isoorg/files/store/en/PUB100397.pdf</a>)
and Declaration for Participants in ISO Activities (<a href="https://www.iso.org/declaration-for-participants-in-iso-activities.html">https://www.iso.org/declaration-for-participants-in-iso-activities.html</a>).

<p class="MsoNormal">P.S. The document SC29/WG3 N0074 that lists all the AHG established at the SC29/WG3 meeting is public, I will share the link to it on this list as soon as it’s available. The text of the working draft amendment of ISO/IEC 14496-22:2019
will be made publicly available for review as soon as the document is ready.<o:p></o:p></p>
