Question 21

Multimedia framework, applications and services

(Continuation of Question 21/16)

The standardization work in Study Group 16 has resulted in the definition of a number of 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 has gained attention from service providers, home networking architectural issues and their impact on broader communications must also be considered.

With the fast development of smart buildings, smart communities and smart cities, requirements for visual surveillance and related applications and services are fast growing. Definition of requirements, architectures and protocols in support of massive successful commercial deployment of visual surveillance is crucial for this Question. To echo the growth trend in intelligent multimedia services and applications, this Question will focus on architectural and protocol issues for typical intelligent multimedia services and applications such as video contents search, multimedia services and applications for intelligent transportation systems, etc.

Furthermore, there is a wide range of fast emerging multimedia services other than traditional multimedia conferencing, which are to be dealt with inside and outside ITU. For example, cloud computing will give rise to new forms of multimedia services and applications since the large computing power embodied in clouds will enable support of rich-media functionalities on thin client devices and attract a large number of users and revolutionize the way people use multimedia services and applications. To cope with these new multimedia services, requirement analysis and definition are important and should be a key area for this Question. There is a need for globally standardized multimedia applications and services, which will fully meet evolving user needs and guarantee the compatibility of multimedia systems and terminals on a worldwide basis.

The objective of this Question is to ensure that the work of multimedia standardization takes place within an architectural framework that promotes integrity of system design, scalability of solutions, reuse of system components, and consistency with the architecture of the broader telecommunication network. Additionally, this Question will study a consistent approach for various generic multimedia applications and services taking into consideration the increasing technical development and convergence of the telecommunication, television and Internet fields and to apply it specifically to the applications and services developed by Study Group 16. The Question can be viewed as addressing multimedia services and applications for "e-everything".

This Question will also address some functions in multimedia service systems that improve service delivery and service implementation are sometimes independent of a particular system and can be provided by common entities or stand-alone systems. One case is of network-based multimedia content delivery functions, which can be used to accelerate media distribution by more efficiently delivering media flows for e.g. IPTV, telepresence and videoconferencing, Internet video, other over-the-top (OTT) video services, visual surveillance, and e-learning.
