Executive Summary

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Executive summary of the SG11 meeting (Geneva, 4-13 March 2020)​

ITU-T Study Group 11 meeting was held in Geneva, from 4 to 13 March 2020 and it was attended by 122 delegates from 36 countries. Among them, 74 participants were connected remotely.
In consultation with ITU Safety and security division and TSB, given the “force majeure” of the coronavirus (COVID-19) and measures to control the epidemy, ITU-T SG11 management team agreed to use interactive remote participation for all sessions during the entire SG11 meeting, including decisions making sessions such as WPs and SG11 opening and closing plenaries. Additionally, it was decided to use “Interprefy” for SG11 opening and closing plenaries as this is the only tool which provides multilingual remote participation. All other sessions (Questions, WPs, CASC and NSP sessions) used the usual remote connection tool via ITU MyWorkspace for SG11. The remote participation instructions are available in SG11-TD1143-R1/GEN.

8     Conformity Assessment Steering Committee
In between two physical SG11 meetings, CASC conducted an e-meeting on 23 January 2020. During this e-meeting, CASC considered the results of the Questionnaire on evaluation of market needs for joint ITU/IEC TL recognition procedure and certification schemes on ITU-T Recommendations (SG11-TD1142/GEN), which was initiated according to the ITU-T SG11 decision in October 2019 (TSB Circular 208). 21 respondents provided feedback on most of the questions of this Questionnaire. According to the results of the survey, most of the replies are positive and the outcomes show interest of different stakeholders to the new joint ITU/IEC services. In this regard, CASC is committed to continuing collaboration with IECEE on TL recognition procedure and joint certification schemes.
The meeting agreed to send a liaison statement to IECEE CMC WG33 (SG11-LS124) informing on the survey’s outcomes and recall about SG11 request (SG11-LS120), seeking their feedback on proposed technologies as candidates for joint ITU/IEC certification schemes (such as safe listening, video surveillance and accessibility features in IPTV systems). Also, IECEE CMC WG33 was requested to provide opinion to consider self-declaration approach for joint certification scheme for video surveillance.

The tenth meeting of the ITU-T Conformity Assessment Steering Committee (CASC), which took place during ITU-T SG11 meeting on 6 March 2020, focused on the feedback received from IECEE CMC WG33 (SG11-TD1192/GEN) on the above mentioned LS sent in January 2020.

From IECEE CMC WG33 perspective, the targeted deadline within 2020 did not seem feasible for establishing ITU/IEC joint certification schemes as the new ITU-T conformity assessment service should be approved by IECEE CMC first.
With regards to the self-declaration approach, IECEE CMC WG33 replied that CB Scheme is based on third party testing and conformity assessment. Therefore, the acceptance of self-declared test results is not possible. However, within the IECEE CB scheme they have the called customers testing facilities (CTFs, OD-2048) that includes the concepts of acceptance of customer created test data under the supervision of their related NCB and CBTL (Test Laboratory).
CASC sent out the reply to IECEE CMC WG33 highlighting the necessity to speed up the adoption of Operational Document being jointly developed, in order to implement the ITU-T conformity assessment service (SG11-LS139).
Additionally, CASC invited ITU-T SG16 (SG11-LS140) to discuss the details on the way forward on proposed candidates for certification schemes and self-declaration approach at the next CASC meeting, which is tentatively scheduled on 24 July 2020 (TBA).
Finally, CASC decided to prepare the report concerning the results of the joint ITU/IEC TL recognition procedure and certification schemes and to request TSB Director to present it at the next Council meeting (Geneva, 9-19 June 2020).

More details are available in the ITU-T CASC report, as contained in SG11-TD1182/GEN.

Preparation for WTSA-20
SG11 arranged several sessions on preparation for WTSA-20 in order to create proposals from SG11 to the next study period, based on the inputs received from SG11 members.

The meeting reviewed all the proposed revised Question texts, new Questions’ texts and text for the mandate of SG11 according to received contributions, based on SG11-TD1069-R1/GEN, which was agreed by SG11 in October 2019.

Initially, there was a plan to finalize Questions texts for next Study Period (2021-2024) in March 2020. However, due to lack of consensus on some proposed new Questions texts, SG11 decided to return to discussion of the left issues during next SG11 meeting, scheduled to take place in Geneva on 22-31 July 2020 (TBA).

SG11 meeting (4-13 March 2020) achieved the following progress:
- Revised and agreed Questions’ texts for A/11, B/11, C/11, D/11, E/11, F/11, G/11, H/11, I/11, J/11, K/11, L/11, M/11;
- WSIS action lines and SDGs were added for each question;
- Questions’ texts N/11, O/11 and P/11 were completed, but all these three Questions require additional discussion;
- SG11 title, mandate, points of guidance, lead SG roles were not changed and SG11 decided to keep changes agreed in SG11 meeting in October 2019.

The latest updated SG11 Questions’ texts, its titles, mandates, points of guidance and lead roles for the next study period are available in SG11-TD1260/GEN.

The draft text contained in SG11-TD1260/GEN should be considered as baseline for WTSA-20 preparatory discussions of SG11 and to be discussed and finalized at next SG11 meeting (22-31 July 2020, Geneva, TBA). Then, after meeting in July, the proposal will be submitted to TSAG and WTSA-20 accordingly.
