IRG-AVA Terms of Reference

​​Terms of Reference for the ITU Intersector Rapporteur Group on Audiovisual Media Accessibility (IRG-AVA)
Version: 2022-02-01
1           Preamble
WTSA Resolution 18 was revised in WTSA-12 to allow for ITU-R experts to jointly develop work with ITU-T experts in a group officially recognized by both ITU-R and ITU-T.
The Intersector Rapporteur Group on Audiovisual Media Accessibility (IRG-AVA) is established in accordance with Annex C of WTSA-12 Resolution 18 and the corresponding provisions in Resolution ITU-R 6 (in line with the Conclusions of the Radiocommunication Advisory Group (RAG) taken at their meeting on 22-24 May 2013, ref. Agenda Item 5 in​).
2           Objectives
Media can be delivered by a number of delivery platforms, including over-the-air broadcasting, cable-casting, IPTV, and Internet. In each case there is an increasing need for access services, for reasons such as the aging population, and the growth of literacy. To ensure that unnecessary differences do not hold back the use of access services, common systems should be used whenever possible.
The IRG will thus consider delivery systems currently in the purview of the ITU-R Study Group 6 and the ITU-T Study Groups 9 and 16).
This IRG will study topics related to audiovisual media accessibility, aiming at development of Recommendations, and other non-normative materials, as appropriate.
This IRG will also address matters contributing to the coordination of the standardization work of the involved ITU-T and ITU-R groups.
The study areas comprise:
  • coordination of the progress of specific topics of mutual interest restricted to the area of audiovisual1 media accessibility including but not exclusively:
  • identification of potential work items that may be jointly progressed as ITU-T and/or ITU-R Recommendations;
  • identification of the challenges to interoperability and access service interoperability requirements. Consideration should also be given to testing and other compliance verification mechanisms;
The IRG-AVA will collaborate with other SDOs, as appropriate, and other audiovisual media organizations (e.g., forums and consortia, research institutes and academia).
3           Relations within and outside ITU-T and ITU-R
While the primary objective of this IRG is to foster coordination and collaboration between the parent groups on the IRG objectives, collaboration with any relevant study group or other relevant groups is encouraged.
Rapporteur groups of other ITU-T and ITU-R groups may join this IRG on request and upon agreement of the parent groups.
The IRG may prepare liaison statements to other groups. The parent groups are to be copied on any such communications.
4           Parent groups
The parent groups of the IRG-AVA are ITU-T Study Group 16, ITU-T Study Group 9 and ITU-R Study Group 6.
5           Leadership
IRG-AVA will be led by a Management Team composed of three experts, each one being nominated by each of the three parent groups. This Management Team represents the core team of the IRG and is expected to expedite the work. Consequently, only persons that have the time and skills to further the work of the IRG should be nominated member of the Management Team.
6           Participation
Participation is open to members of ITU-T and ITU-R that can participate in the work of the ITU-T and ITU-R parent groups. The IRG-AVA Management Team may invite individual experts as appropriate and in accordance with the rules for parent group meetings of ITU-T and ITU-R.
A list of participants will be maintained for reference purposes and reported to the parent groups as an attachment to the report of each meeting (see clause 9).
7           Deliverables
An IRG may draft new or revised Recommendations, as well as other non-normative materials.
These deliverables, upon consensus within the IRG, will be submitted to its parent study groups for further consideration following the rules and practices of the parent group to which the deliverable is assigned.
IRG-AVA will identify such deliverables and make pertinent proposals to its parent study groups (see clause 8).
Each parent group will be responsible for their own Recommendations. Any joint text Recommendations will be approved in a coordinated manner by the parent groups. Joint texts should as much as possible be technically aligned.
The results of an IRG's work are to represent the agreed consensus of the IRG, or reflect the diversity of views of the participants in the IRG.
8           Meetings
The frequency and location of meetings will be determined by the IRG and the overall meetings plan should be announced as soon as possible. See also clause 11 "Working Guidelines" below.
The meetings will be announced by electronic means (e.g., mailing lists and on the ITU website) at least two months in advance of the meeting.
The IRG will use remote collaboration tools to the maximum extent, and when physical meetings are deemed necessary, they should collocate with other planned physical meetings from which synergies can be derived (in particular that of the parent groups, of their working parties, or of related interim rapporteur group meetings).
9           Meeting reports
This IRG shall prepare reports on its meetings and activities, to be submitted to the next meeting of its parent study groups. The information in such reports should contain the items listed in Recommendation ITU‑T A.1 Appendix I.
10         Working language
The working language of this IRG will be English.
11         Working guidelines
This IRG will work by consensus.
This IRG is regulated by the provisions applicable to rapporteur groups, given in Resolution ITU‑R 1-6 and in Recommendation ITU-T A.1 (see also the ITU-T manual for rapporteurs and editors at​).
Additionally, the IRG will follow the guidelines found in WTSA-12 Resolution 18, Annex C, and in the corresponding provisions in Resolution ITU-R 6 (in line with the Conclusions of the Radiocommunication Advisory Group (RAG) taken at their meeting on 22-24 May 2013).
12         Patent policy
The Common Patent Policy for ITU-T/ITU-R/ISO/IEC shall be used.
13         Termination of the IRG-AVA
As the start and end dates of the ITU-R and ITU-T Study Periods do not coincide, each member Study Group should indicate their intention to withdraw from IRG-AVA by sending a liaison statement to the other two Study Groups2 at the end of their Study Period (or at any time during a Study Period if required.​

1 The term “audiovisual” in the context of this Terms of Reference is deemed to include any format or medium or platform that offers or engages an audience by employing sensory based technologies such as audio, video, or haptic and enables or enhances any form of accessibility, interaction or control of content or information presented.
2 It will be assumed the Study Group wishes to continue taking part in the IRG-AVA activities if no liaison statement is sent.
