1 Motivation
The standardization work in Study Group 16 (now ITU-T Study Group 21) has resulted in the definition of several multimedia systems. ITU-T H.610 defines a multiservice system architecture and customer premises equipment architecture for the delivery of video, data and voice services across a VDSL access network to an in-home environment, and the H.700-series defines a family of IPTV protocols. As broadband services over various access technologies have evolved and given that the desire for the delivery of multimedia services to the home and other service platforms has gained attention from service providers, networking architectural issues and their impact on broader communication systems and services must also be considered.
This Question is intended to produce the deliverables related to multimedia standardization work including multimedia related networks, enabler platform and services, core audio and video technologies, multimedia data analysis, various multimedia services and applications, including information-centric networks (ICNs), unified status monitoring, media processing, interactive and distribution service, multimedia data asset management, virtual and augmented reality (VR/AR), distance learning services, digital human and digital twin, etc. The Question will also focus on emerging multimedia related content including multimedia aspects of metaverse.
2 Study items
Study items to be considered include, but are not limited to:
- identify multimedia services and applications that are studied by ITU and other bodies and produce a map of their interrelationship;
- study of multimedia system, service and application based on cutting-edge technologies including multimedia aspects of metaverse by collecting use cases, identifying requirements, defining architectures and developing underlying protocols;
- identify the services and applications to be explored by Study Group 21 and define their respective scopes, requirements and contribute to the development of technical specifications;
- study network-related multimedia framework, applications, and services, which built for various multimedia systems, e.g. cloud computing systems, edge computing systems, etc., and underlying; networks, network context awareness and adaption, information-centric networks, error-prone networks, mobile edge networks, etc;
- study media streams transport: generic formats and encapsulation methods of various media streams for the purpose of transport over heterogeneous networks (in coordination with relevant IETF WGs such as AVTCORE);
- study multimedia enabler platforms and services, such as media processing, distribution and interaction, etc;
- study multimedia data analysis related technology, solutions, services and regulations;
- study of cloud and edge computing-based multimedia services and applications by identifying requirements, defining architectures and developing underlying protocols;
- study mobile edge computing (MEC)-related multimedia services, such as MEC based VR/AR applications, traffic information monitoring and management, etc.;
- study smart device-based multimedia application and services (such as smart speaker based audio/video communication, set-top box based multimedia communications) as well as their advanced presentation forms on ultra-high definition, VR and holographic communication;
- study internet-based streaming media services, such as online education, video based online shopping, video based social services, live event broadcast, video based marketing, online corporate training, online medical diagnosis, call service, etc.
3 Tasks
Tasks include, but are not limited to:
- documentation of architectural assumptions made by previous work on multimedia standardization (H- and T-series Recommendations) and production of the scope, use cases, and requirements capture for the services and applications under Study Group 21 responsibility;
- study use cases, requirements, framework, functional architectures on multimedia aspects of metaverse technologies, applications, systems and services;
- study the use cases, requirements, framework, functional architecture and protocols for and, if needed, create F- and H-series Recommendations to cover new multimedia technology, systems, applications and services, e.g.:
o retrieval services, including interactive audiovisual and multimedia services;
o real-time collaboration services;
o intelligent multimedia services and applications;
o cloud and edge computing-based multimedia services and applications;
o MEC-based multimedia services and applications;
o multimedia data analysis architecture and related application and services;
o Internet-based streaming media services;
o network-related multimedia framework, applications, and services;
o enhanced multimedia call service;
- identify requirements for service-agnostic multimedia service functions;
- develop service-agnostic architecture specifications, such as the inspection technology, inspection policy, delivery function, robustness, etc.;
- coordinate with ITU-T Study Groups 2, 11, 12, 13, 15, 17, 20 and other groups to advance multimedia services and applications related work;
