Annex A - Question 5/16 (Q.MM-AI) - Artificial intelligence-enabled multimedia applications

Motivation

The recent success of Artificial Intelligence (AI) in various applications has raised study and utilization of AI technology to a new height. AI has been the apex technology of the information age. One of the most exciting aspects of the AI inflection is that “real-world” use cases abound. At the same time, deep-learning enabled advances in computer vision and such technologies as natural language processing are dramatically improving the quality of people’s work and life.
At present, the ecological pattern of AI has been established gradually. In future years, specialized intelligent applications will be the main potential area for the future development of AI. No matter whether it is a specialized or generalized application, the enterprise layout of AI will focus on three basic levels; data, computing layer (base), algorithm layer (technology) and application layer. AI is not just “tech for tech”. Where large data sets are combined with powerful enough technology, value is being created and competitive advantage is being gained.
Multimedia has become the pioneer, and the concept of “AI-enabled Multimedia” as well as “Intelligent Multimedia” has already come up. Scientists, engineers all over the world are delving into some of the most exciting areas such as computer vision and speech technologies. Computers are being taught to understand video, augmenting reality to guide field technicians when operations get complex, helping computers recognize people, detect sentiment and speak with emotion, and enrich video with metadata extracted from it.
AI-enabled multimedia applications are booming, but focused studies are far behind. Emerging technologies brings not only new opportunities, but also new challenges as well as new demands. Taking multimedia data as an example, image, video and sound data are the fuel of AI applications such as recognition, sentiment classification, etc. However, huge volume multimedia data does not indicate high quality labelling data that AI applications could benefit. No guidelines or standards of multimedia format, labelling are developed, multimedia data collected and labelled by company A could not be used in company B, which results in huge resource waste and prevent the data flow, which severely hindered the development of AI industry.
This Question focusses on artificial intelligence-enabled multimedia applications, to identify challenges facing the deployment of AI-enabled multimedia applications, to analyze the impact of AI technologies in standards for multimedia applications, and to identify evaluation and assessment specifications of service, algorithm and data for standards in AI -enabled multimedia applications, in order to boost and innovate the development of multimedia as well as AI industry.

Annex B - Draft new Question 22/16 (Q.MM-DLT) - Distributed ledger technologies and e-services

Motivation

A distributed ledger is a consensus of replicated, shared, and synchronized digital data geographically spread across multiple sites, countries, or institutions. There is no central administrator or centralized data storage.
Distributed ledger technologies (DLT) are secure by design and exemplify a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a DLT system. This makes DLT potentially suitable for the recording of events, medical records, and other records management activities, such as identity management, transaction processing, documenting provenance, food traceability, and voting.
A range of standardisation-related and industry initiatives have commenced across the globe examining different aspects of DLT/Blockchain. Various activities, including exploratory workshops and cross-industry collaboration initiatives, such as the Hyperledger project have served as forums for discussion of potential technical challenges around the widespread adoption of DLT.
An ITU-T Focus Group on Application of Distributed Ledger Technology (FG DLT), was established May 2017 under the auspices of TSAG. The focus group addresses a number of topics of DLT, for example, use-cases and applications, requirements for the implementation, regulatory and policy aspects, security and privacy aspects, among many other aspects.
ISO/TC 307 develops standards on DLT/Blockchain based on the market need.
ITU-T SG16 is a leading group of e-services and multimedia applications. DLT technology has a good potential of new technology and multimedia applications that needs trusted infrastructure. SG16 does not have the explicit group to discuss the above problems.
This Question develops Recommendations on Distributed Ledger Technologies and DLT based e-services.

Study items

Study items to be considered include, but not limited to:

• ​Concepts, coverage, vision and use cases of multimedia applications and e-services based on DLT.
• Characteristics and requirements for multimedia applications and e-services based on DLT.
• Architectural framework and communication technologies of multimedia applications and e- services based on DLT.
• Analyse and evaluate the current status of DLT and its maturity to support multimedia applications and e-services.
• Research on consensus algorithm for different multimedia applications and e-services with various requirements on DLT
• Investigation of digital assets of multimedia applications and e-service on DLT, including management, exchange and etc.
• General requirements and framework for DLT.
• Research security and privacy aspects related to multimedia applications and e-services based on DLT.
• Examine means for extending on-line trust in the context of multimedia applications and e-services using DLT.
• Identify stakeholders with whom ITU-T could collaborate further on and potential collective actions and specific next steps.

NOTE – This Question will take into consideration identified policy and regulatory implications of application of DLT in multimedia applications and e-services.

Tasks

Tasks include, but not limited to:

• ​Utilize the deliverables related to DLT that were produced by relevant ITU-T Focus Groups (e.g. FG DFS, FG DFC, FG DLT), and study gaps among those groups and what need to be achieved.
• Develop documents which reflect how technologies enable applications and services by the underlying nature of the ecosystem taking into account existing applicable best practices of risk assessment methodologies and business models.
• Develop Recommendations on the definitions of terminologies, taxonomy, reference architecture, testing and evaluation for DLT infrastructures and DLT for multimedia applications and e-services.
• Study and analyse the implications of mandating interoperability and interconnection of services based on DLT. This will include the development of a standardization roadmap for interoperable services based on DLT taking into consideration the interoperability challenges and best practices.
• Study and analyse technology competitiveness issues that may hinder the deployment of multimedia applications and e-services based on DLT.
• Develop technical reports describing and addressing the standardization gaps and identifying future standardization work for ITU-T study groups in the area of multimedia applications and e-services based on DLT.

Other topics can also be studied, as appropriate, based on contributions.
