Review the text of ISO/IEC CD 14496-22 Draft International Standards amendment 2 and submit ballot comments, if applicable.<o:p></o:p></p><p class=MsoNormal>2. Review publicly available WG3 output documents and propose additional changes and updates.<o:p></o:p></p><p class=MsoNormal>3. Explore potential future changes and updates, and propose new items (if applicable) for consideration in the 5th edition of the OFF specification.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Please note:<o:p></o:p></p><p class=MsoNormal>1. The text of the 2<sup>nd</sup> amendment has been published under ballot after it was promoted to the Draft International Standard stage [in October 2021], and the ballot is still open (until April 8, 2022). Both editorial changes and minor technical corrections can still be introduced as ballot comments, which you can submit for discussion in this AHG or submit them directly to ISO Secretariat via your National Body.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>2. At the last meeting, the proposed CFF2 updates were discussed and approved, and following this group’s recommendation, the WG3 has approved the creation and publication of the new, 5<sup>th</sup> edition Working Draft of ISO/IEC 14496-22 OFF. The full version of the WD won’t be available for some time since it requires merging of the 4<sup>th</sup> edition text with two prior amendments; however, the text of the proposed CFF2 updates has been made available for public review as a standalone document “Technology under consideration for OFF” and can be downloaded from public MPEG website: <a href="https://www.mpegstandards.org/wp-content/uploads/mpeg_meetings/137_OnLine/w21213.zip">https://www.mpegstandards.org/wp-content/uploads/mpeg_meetings/137_OnLine/w21213.zip</a>. (All publicly available documents, including the 5<sup>th</sup> edition WD, will be posted there as well: <a href="https://www.mpegstandards.org/meetings/mpeg-137/">https://www.mpegstandards.org/meetings/mpeg-137/</a>.)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>3. Our third mandate remains unchanged. The 5<sup>th</sup> edition WD offers an opportunity to conduct a full review of the OFF text and introduce both technical and editorial changes following the established ISO process. There is no urgency in finalizing the 5<sup>th</sup> edition text – we are encouraged to explore potential future changes and updates and submit them for discussion both in this AHG and in the future WG3 meetings.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thank you,<o:p></o:p></p><p class=MsoNormal>Vladimir<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
