Major accomplishments

• Preparations towards next study period: Study Group 16 completed its proposal on Questions [TD 514/Plen] and updates to its mandate [TD 513/Plen]. In particular, it was recognized that standardization on e-services has increased in the past four years, and is expected to grow. Eleven Questions are proposed to WTSA-16, ten as continuation or merger of existing Questions, plus one new Question on immersive live experience systems (see below). The final text of Questions and study group mandate updates to WTSA-16 will be found in WTSA-16 Docs 17 (Chairman's report and mandate) and 18 (Questions).
• It was agreed not to continue JCA-IPTV in the next period and to organize one last IPTV-GSI event in Geneva, 12-16 September 2016. However, it was agreed to establish a JCA on e-services, with terms of reference in [TD 573/Plen].
• Work has started on systems for immersive live experience (ILE), which will bring the sensation of live events to remote audiences, replicating the experience of being present at the event venue. This work will create a multimedia environment in which viewers will experience realistic perceptions of sound, lighting and space. The new group will meet for the first time during the IPTV-GSI event in September 2016. (Interview)
  
• The ITU-T Software Tool Library (ITU-T G.191 STL) for speech codec development, which has had an open source license since its original version in the early 1990s, was made an open source project, to facilitate contribution and maintenance by a wider number of speech coding developers, including industry and media. SG16 also agreed to transfer future upkeep of the STL to ITU-T SG12, were we find today the largest set of ITU users of the library.
• IPTV services: Three new Recommendations were completed: ITU-T H.703 (ex H.IPTV-EUIF) defines an enhanced user interface framework for IPTV terminal devices [TD 545/Plen], ITU-T H.723 (ex H.IPTV-TDES.4) provides the characteristics and requirements for mobile IPTV terminal devices [TD 546/Plen] and ITU-T H.742.0 (ex H.IPTV-UVS) specifies the architecture and requirements for the use of video sensor devices for IPTV services [TD 547R1/Plen]. Additionally, revised Technical Paper ITU-T HSTP-MCTB approved at this meeting now contains a description of use of H.265 HEVC in IPTV systems [TD 559/Plen].
• Accessibility: New work has started to specify the conformance testing of accessible IPTV terminals implemented according to ITU-T H.702. Technical Paper ITU-T FSTP-UMAA on use cases for assisting people with disabilities using mobile applications was approved at this meeting [TD 565/Plen].
• E-health: Two major updates were Consented to the personal connected health specifications in the H.810-H.850 series:

[TD 491/Plen, TD 492/Plen, TD 517/Plen, TD 518/Plen, TD 519/Plen, TD 493/Plen, TD 494/Plen, TD 495/Plen, TD 496/Plen, TD 497/Plen, TD 498/Plen, TD 515/Plen, TD 516/Plen, TD 520/Plen, TD 521/Plen, TD 522/Plen, TD 523/Plen, TD 524/Plen, TD 525/Plen, TD 534/Plen, TD 535/Plen, TD 536/Plen, TD 537/Plen, TD 538/Plen, TD 526/Plen, TD 527/Plen, TD 528/Plen, TD 529/Plen, TD 530/Plen, TD 531/Plen, TD 532/Plen, TD 533/Plen, TD 539/Plen, TD 540/Plen, TD 541/Plen, TD 542/Plen, TD 543/Plen].
  Approval of the set of 45 Recommendations is expected for mid-July 2016.
• Safe listening: the collaboration with WHO has continued for the development of technical standards for safe listening music players. The baseline text in draft ITU-T F.SLD has progressed, and a workshop was organized following the SG16 meeting with the presence of industry representatives, users, WHO, and ITU-T SG12 and CENELEC TC 108X experts.
• Digital multimedia transport: Common text ITU-T H.222.0 | ISO/IEC 13818-1 is used in most terrestrial and satellite system for transport of audiovisual content, and it had two corrigenda and three amendments Consented. They include new profiles and levels for MPEG-4 audio descriptor (Amd.4), carriage of MPEG-H 3D audio over MPEG-2 systems (Amd.5) and carriage of quality metadata in MPEG-2 systems (Amd.6) [TD 554/Plen, TD 555/Plen, TD 556/Plen]. Corrigendum 1 to Amd.2 provides clarifications and corrections on pause flag, URL construction and adaptation field syntax (Amd.1 Cor.2); Cor.1 corrects the PES header table and removes of semantic element from clause 2.6.61 (Cor.1) [TD 553/Plen, TD 552/Plen].

Summary of Questions' Results

Question 1/16 summary

Q1/16 had a successful meeting and reviewed several input documents pertaining to the common text ITU-T Rec. H.222.0 | ISO/IEC 13818-1. They resulted in two corrigenda and three amendments proposed for Consent. The Question does not plan on holding any interim Rapporteur Group meeting and did not prepare any outgoing LSs. In the next study period, the Question will be merged with current Q2/16, Q3/16, and Q5/16, into a new Q1/16.

Question 2/16 summary

Question 2/16 met for two quarters during this study group meeting, working to progress the work items planned for Consent or approval. While able to produce stable output text of documents originally planned for Consent, it was not possible to put those documents forward for Consent due to dependencies on IETF documents that have not yet been published as RFCs. The Question completed one document for approval at this meeting. Q2/16 did not prepare any outgoing liaison statements and does not plan an interim Rapporteur Group meeting before the next SG16 meeting. The Question did not propose to continue as an independent Question in the next study period; rather, its mandate and existing work items will be continued in the new Q1/16, which is the merger of Questions 1/16, 2/16, 3/16 and 5/16.

Question 3/16 summary

Question 3/16 met for 2 quarters to review 35 documents. Q3/16 continued work on a number of existing work items which has resulted in one Recommendation Revised H.248.50 on NAT Traversal for Consent. One new work item was initiated, revised H.248 Sub-series IG. No liaison statements were prepared at this meeting and the Question is not planning on meeting before the end of the study period. The Question is not proposing to continue as an individual Question in the next study period and the current work items will be handled in the new Q1/16.

Question 5/16 summary

Question 5/16 had a successful meeting, and progressed work on the two remaining work items. Three contributions on audio/video parameters and signalling were presented and discussed.  Updated baseline text for H.TPS-AV and H.TPS-SIG was prepared and accepted.  Both H.TPS-AV and H.TPS-SIG are ready for consent as soon as the IETF drafts referenced in these work items are published. One input liaison statement was reviewed, and no output liaison statements were prepared. The Question is not planning on holding an interim Rapporteur meeting. The Question is not being proposed to continue as an individual Question in the new study period; current open work items will be transferred to a new Q1/16.

Question 6/16 summary

The primary goals for Question 6/16 at this meeting of SG16 were to review the progress of Q6/16, JCT-VC, JCT-3V, JVET, and JPEG work, and reach AAP Consent on revised Recs. H.264 (V11), H.265 (V4), H.265.1 (V2), H.265.2 (V3), T.832 (V3), and T.835 (V3) and on the new Rec. H.273 (ex H.STI). A substantial portion of the image coding work of Question 6/16 has been 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 three joint collaboration groups, known as the Joint Collaborative Team (JCT) on Video Coding (JCT-VC), the Joint Collaborative Team (JCT) on 3D Video Coding (JCT-3V), and the Joint Video Exploration Team (JVET). Meetings of JCT-VC, JCT-3V, and JVET were held in a collocated fashion with this meeting of SG16 under its auspices. The JCT-VC is tasked with development of extensions to High Efficiency Video Coding (HEVC, Rec. ITU-T H.265). The JCT-3V has been tasked with development of 3D video coding extensions, but has completed its assigned work and will discontinue meeting in the future. Future work in the former domain of JCT-3V will be handled by Q6/16 and MPEG with collaborative communication exchange. JVET is exploring the potential for developing a future video coding standard with substantially improved coding performance relative to HEVC. Meetings of MPEG and JPEG were also held in a collocated fashion during the current meeting of SG16, and joint discussions were held with these groups and Q6/16. Q6/16 is planning to hold one Rapporteur meeting, one JCT-VC meeting, and one JVET meeting before the next SG16 meeting in January 2017 and to hold a meeting of the JCT-VC and of the JVET in a collocated fashion with the next SG16 meeting in January 2017 under its auspices. The Question prepared four outgoing Liaison Statements. The text of Question 6/16 was updated in preparation for continuation of its work in the next Study period.

Question 7/16 summary

Question 7/16 which addresses mainly coordination aspects of media coding did not receive any contributions and no sessions were held during the SG16 meeting.
