The ITU-T Study Group 16 (SG16) is a statutory group of the
ITU Telecommunication Standardization Sector

, including on safe listening (
H.870) accessibility of e-health (
F.780.2), it is also the parent body of
VCEG
The Video Coding Experts Group or Visual Coding Experts Group (VCEG, also known as Question 6) is a working group of the ITU Telecommunication Standardization Sector (ITU-T) concerned with standards for compression coding of video, images, audio ...
and various Focus Groups, such as the
ITU-WHO Focus Group on Artificial Intelligence for Health and its
AI for Health Framework.
Administratively, SG16 is a statutory meeting of the
World Telecommunication Standardization Assembly (WTSA), which creates the ITU-T Study Groups and appoints their management teams. The secretariat is provided by the Telecommunication Standardization Bureau (under Director
Seizo Onoe). WTSA instructed ITU to hold the
Global Standards Symposium as a part of the deliberations that is open to the public.
The goal of SG16 is to produce Recommendations (international standards) for
multimedia
Multimedia is a form of communication that uses a combination of different content forms, such as Text (literary theory), writing, Sound, audio, images, animations, or video, into a single presentation. T ...
, including e.g.
video coding,
audio coding and image coding methods, such as
H.264,
H.265,
H.266, and
JPEG
JPEG ( , short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degr ...

. It is also responsible for "the coordination of related studies across the various ITU-T SGs." Additionally, is also the lead study group on ubiquitous and Internet of Things (IoT) applications; telecommunication/ICT accessibility for persons with disabilities; intelligent transport system (ITS) communications; e-health; and Internet Protocol television (IPTV).
Trustworthy AI
Together with
ITU-T Study Group 17 and
AI for Good, the study group has been developing technology specifications under
Trustworthy AI. Including items on
homomorphic encryption
Homomorphic encryption is a form of encryption that allows computations to be performed on encrypted data without first having to decrypt it. The resulting computations are left in an encrypted form which, when decrypted, result in an output th ...

multi-party computation, and
federated learning
Federated learning (also known as collaborative learning) is a machine learning technique in a setting where multiple entities (often called clients) collaboratively train a model while keeping their data Decentralized computing, decentralized, ra ...
