Major accomplishments

• New Questions: The two Questions proposed at the previous SG16 meeting held had their inaugural sessions at this meeting after completing the approval process: Q5/16 "Artificial intelligence-enabled multimedia applications" and Q22/16 "Distributed ledger technologies and e-services". The meeting also agreed with the proposal for a new Question 12/16 on "Visual surveillance systems and services", which needs review by TSAG before being formally adopted. Nevertheless, work will already start by taking on work items that were previously handled in Q21/16. The text is found here.
• ITU Workshop on "Enhancing Human Life Using e-Services", collocated with the ITU-T SG16 meeting, took place on 25 March 2019. The workshop explored how e-services can improve life outcomes in our increasingly digital lives, by addressing technologies including artificial intelligence for areas such as health and agriculture as well as the core standardization challenges in ICT accessibility. It also addressed the issue of procurement of accessible ICT services and products. The main highlights of the workshop are given in SG16-TD279/Plen.
• Video and image coding: Completed work on two revised video coding Recommendations at this meeting:
  • ITU-T H.264 V13 "Advanced video coding for generic audiovisual services" [SG16-TD294/Plen]
  • ITU-T H.265 V6 "High efficiency video coding" [SG16-TD295/Plen] 
  Experts also completed new H-Series Supplement 19 with code points for different sets of video signal properties and their combinations that are widely used in production and video content workflows. The information in this Supplement will help producers of various content processing tools avoid processing mistakes that can cause video quality degradation due to having incorrect assumptions made about video property combinations [SG16-TD296-R1/Plen].​
  
  ​The following image coding Recommendations were also completed:

Summary of Questions' Results

Question 1/16 summary

Q1/16 met in three sessions to review 18 incoming liaison statements directed at Q1/16 were reviewed and necessary outgoing liaisons were prepared. Some important subjects related to WTSA-20 preparations and next study period were covered in Q1/16 discussions which are mainly based on the outcomes of the two ad-hoc brainstorming sessions on these subjects.

Question 5/16 summary

Question 5/16 (Artificial intelligence-enabled multimedia applications) formally started its work at this SG16 meeting. The focus of this meeting was in understanding the future steps, including the development of a standardization roadmap and the definition of a technical systematic architecture. The Question also reviewed a number of incoming liaison statements, but did not produce any outgoing LSs. The Question plans one interim meeting and contributions are invited.

Question 6/16 summary

The primary goals for Question 6/16 at this meeting of SG16 were to review the progress of Q6/16, JVET, JCT-VC, and JPEG work. It reached AAP Consent on five revised and two new Recommendations on topics related to the coding of video and still images (H.264 V13, H.265 V6, T.800 V3, T.814, T.815, T.832 V4, and T.873). Q6/16 also submitted a new supplement (H-series Supplement 19) for Approval, describing prevalent industry usage of video signal type code points. A substantial portion of the image coding work of Question 6/16 is conducted jointly with ISO/IEC JTC 1/SC 29/WG 1 (JPEG/JBIG), and a substantial portion of the video coding work of Question 6/16 is being conducted jointly with ISO/IEC JTC 1/SC 29/WG 11 (MPEG) in two joint collaborative teams known as the Joint Video Experts Team (JVET) and the Joint Collaborative Team on Video Coding (JCT-VC). Meetings of JVET and JCT-VC were held in a collocated fashion with this meeting of SG16 under its auspices. JVET is tasked with development of Versatile Video Coding (VVC), a future video coding standard with substantially improved coding efficiency relative to HEVC (H.265). A meeting of MPEG was also held in a collocated fashion during the current meeting of SG16, and a joint discussion session was held with that group and Q6/16. Q6/16 is planning to hold one Rapporteur meeting, one JVET meeting, and one JCT-VC meeting before the next SG16 meeting in October 2019 and to hold meetings of JVET and the JCT-VC in a collocated fashion with the next SG16 meeting in October 2019 under its auspices. The Question prepared four outgoing Liaison Statements.

Annex A: Draft new Question 12/16
​"Visual surveillance systems and services"

(New Question, ex Q.VS)

Motivation

A visual surveillance system is a telecommunication system which is used to remotely capture and present multimedia to the end user via networks with ensured quality, security and reliability.
In the past decade, there has been significant development in security industry worldwide, and visual surveillance applications are becoming more and more popular in both developed and developing countries. According to a recent research report, the global visual surveillance market is expected to grow from 36.89 billion US dollars to 68.34 billion US dollars from 2018 to 2022, with a compound annual growth rate of 13.1%. The potential market is huge.
There is a growing need of interworking between visual surveillance systems for communications. For visual surveillance, cloud computing, cloud storage, edge computing, edge storage, AI, big data, and intelligent analysis are needed in addition to video acquisition, coding, transmission, distribution and storage. Visual surveillance is no longer a traditional independent service, but a whole ecosystem, highly connected to smart city and safe city construction. Standards should be used to support the development of the industry, and meet the need of rapid development. In addition, new information technologies continue to emerge, and the visual surveillance platform should be open to and capable of continuous evolution. The scope of the visual surveillance standards should be expanded to align with the market and to promote the development.
A range of standardization-related and industry initiatives have commenced across the globe examining different aspects of visual surveillance. There are various activities, including international exhibitions, and exploratory workshops. Open Network Video Interface Forum (ONVIF) was established in May 2008, aiming at providing and promoting standardized interfaces for effective interoperability of IP-based physical security products. At present, ONVIF has released two versions of core specifications, two data format specifications, six profiles and 22 service specifications. The IEC TC 79 WG12 is focusing on video surveillance system (VSS) to produce IEC standards for VSS and applications taking into account the system, component and equipment requirements, testing and integration. Many other SDOs such as ISO/IEC JTC1, 3GPP and ETSI are also developing visual surveillance standards according to their scope.
ITU-T SG16 developed various Recommendations on visual surveillance, including ITU-T F.743 series, H.626 series and H.627 series. Furthermore, many new work items are being developed in ITU-T SG16. In order to meet the strong standardization need from the industry and accommodate the existing work with ITU-T, including the enhancement and maintenance of the Recommendations and development of ongoing many work items, it is necessary to create a new Question on visual surveillance.
The following major Recommendations, in force at the time of approval of this Question​, fall under its responsibility: ITU-T F.743, F.743.1, F.743.2, F.743.3, H.626, H.626.1, H.626.2, H.626.3, H.626.4, H.627, H.627.1.
