Future meeting plans, expressions of thanks, and closing of the meeting

Future meeting plans were established according to the following guidelines (assuming face-to-face meetings):

• Meeting under ITU-T SG16 auspices when it meets (ordinarily starting meetings on the Tuesday or Wednesday of the first week and closing it on the Wednesday of the second week of the SG16 meeting – a total of 8 meeting days), and
• Otherwise meeting under ISO/IEC JTC 1/‌SC 29 auspices when its MPEG WGs meet (ordinarily starting meetings on the Friday prior to the main week of such meetings and closing it on the same day as other MPEG WGs – a total of 8 meeting days).

In cases where an exceptionally high workload is expected for a meeting, an earlier starting date may be defined. In cases of online meetings, no sessions should be held on weekend days, such that meetings would typically start two days earlier.

Some specific future meeting plans (to be confirmed) were established as follows:

• During Fri. 13 – Fri. 20 October 2023, 32^nd meeting under ISO/IEC JTC 1/‌SC 29 auspices in Hannover, DE,
• During Wed. 17 – Fri. 19 and Mon. 22 – Fri. 26 January 2024, 33^rd meeting under ISO/IEC JTC 1/‌SC 29 auspices, to be held as teleconference meeting,
• During Fri. 19 – Fri. 26 April 2024, 34^thmeeting under ITU-T SG16...
