Summary of Questions’ Results

Question 1/16 Summary
Question 1/16 had a successful meeting and principally worked on progressing CS-IMS interworking in H.324/M. Several recommendations of the H.320-series and H.324 were revised at this meeting. Q1/16 reviewed some input documents concerning changes to ITU-T H.222.0 | ISO/IEC 13818-1. Q1/16 proposed four Recommendations, one amendment and one corrigendum for Consent (H.222.0 Cor. 2, H.222.0 Amd.3, H.221, H.230, H.242, and H.324). It was agreed that Last Call for H.324 would be delayed until 30 March 2009 to allow extended review opportunity to the experts.

Question 2/16 Summary
Question 2/16 reviewed several matters in relation with enhancements to the existing standards, allowing for features such as multi-language caller and called party identification, conference list features and master/slave designation. The NAT/firewall traversal work on H.460.23 and H.460.24 was progressed during this meeting and the text of those two proposed new recommendations is getting close to finalization. The H.323 Implementors’ Guide (i.e., collection of defect reports) was revised at this meeting and proposed for Approval and Q2/16 produced a Corrigendum to H.235.6.

Question 3/16 Summary
Question 3/16 reviewed some 108 documents. It continued work on a number of existing work items which has resulted in 13 Recommendations for Consent: Revised H.248.14, H.248.19 Amd.2, Revised H.248.42, H.248.52 Amd.1, Revised H.248.53, H.248.56 Cor.1, New H.248.60, New H.248.61, New H.28.63, New H.248.65, New H.248.68, New H.248.69 and New H.248.70. In addition to these Recommendations Q3/16 prepared two documents for approval: Revised H-Series Supplement 2 “Packages Guide” and the H.248 Sub-Series Implementors’ Guide. Q3/16 started four new work items: revised H.248.4, revised H.248.5, new H.248.MRCP and new H.248.PACKETS. Q3/16 prepared two Liaison Statements.

Question 4/16 Summary
Question 4/16 has completed work on the draft new Supplement ITU-T H.hnqos.analysis “Analysis of Class-based Home Network QoS Solutions.” It was agreed to move the document forward for Approval at this meeting. In addition, Q4/16 made some progress in the work on the draft new Rec. ITU-T H.codec.qoe “An Adaptive QoE Control Framework based on Variable Bit Rate Codec in Wireless Networks” by providing more functional descriptions of components of the framework.

Question 6/16 Summary
A substantial portion of the work of Question 6/16 is also conducted jointly with ISO/IEC JTC 1/ SC 29/WG 11 (MPEG) in an organization known as "the JVT" (Joint Video Team) and with ISO/IEC JTC 1/SC 29/WG 1 (JPEG/JBIG). A meeting of the JVT has been held in a co-located fashion with this meeting of SG 16. The ongoing JVT work is currently concentrated on the maintenance and development of extensions for Rec. H.264 (a Twin Text Recommendation with ISO/IEC 14496-10) and associated Rec. H.264.1 conformance and Rec. H.264.2 reference software, including work on multi-view video coding (MVC) and supplemental enhancement information (SEI). The primary goals for Q6/16 at this meeting of SG 16 were to review the progress of Q6 and JVT work, to reach AAP Consent on those work items that have reached sufficient maturity, and to plan future work.

Question 7/16 Summary
Question 7/16 experts agreed to move for approval the technical paper HSTP.MCTA on Toolbox for Content Coding (Audio codecs part). The different incoming LS were also addressed. One interim meeting is planned 6-10 July 2009.

Question 8/16 Summary
Question 8/16 made good progress during this meeting. The GSAD Terms of Reference have been approved, and initial drafts of performance evaluation and processing plans developed. It has been agreed to move forward with a selection phase to evaluate candidate GSAD algorithms (fixed point), with a schedule leading to Consent of a new Recommendation in October 2009. One interim meeting is planned 6-10 July 2009.

Question 9/16 Summary
Question 9/16 discussed the validation of the floating point Annex to G.718, based upon Rec. ITU-T P.862.2 scores for the Optimization/Characterization Phase I test conditions. It was agreed that the floating point version of G.718 provides comparable performance to the fixed point code. A new draft Amendment 1 to Recommendation ITU-T G.718 was compiled and agreed for Consent during the meeting, which contains, in addition to the G.718 floating point extension, a series of corrections to the fixed-point C-code and the text of G.718. The subjective tests of the Optimization/Characterization Phase II were reported to be under way and would be completed in time for a review of results by SG12 at their March 2009 meeting. The results of SG12 deliberations will then be reviewed by Q9/16 at a future meeting (possibly in July 2009). Question 9/16 will also draft Technical Paper with performance testing data for G.718 in close coordination with Q10/16 (which will be producing equivalent information for the other speech and audio codecs standardized by ITU). One interim meeting is planned 6-10 July 2009.

Question 10/16 Summary
The main outcome of Question 10/16 for this meeting is as follows. Two new Amendments were Consented: G.719 Amd.2 with new Annex C for G.719 packet format identifier and capability parameters, and G.711.1 Amd.2 with new Annex B for usage within H.245 together with some corrections to the text of the G.711.1 Recommendation. For superwideband extension to G.711.1 and G.722, qualification phase has been prepared and the stereo part of the terms of reference (ToR) has been agreed. The time schedule of this work item has been reviewed and agreed and the Qualification meeting will be in early July 2009. For G.711 lossless compression, the preparation of the selection phase has been finalized. The time schedule of this work item has also been reviewed and agreed. The Consent meeting for the outcome of this work item is foreseen at next WP3/16 plenary meeting in early July 2009. As for superwideband extension to G.718 and G.729.1, the list of conditions has been finalized and agreed. The time schedule has been reviewed and a modified version was agreed. The Consent meeting is foreseen at next SG16 plenary meeting. The next release of the ITU-T Software Tool Library (STL) is under preparation and it is foreseen to be ready for Consent in October 2009. Studies started for extension of G.711 PCM to achieve higher quality: a new work item was launched to explore quality enhancement via pre- and post-processing. The list of test conditions to assess the quality of these pre- and post-processing has been discussed and agreed. The approval of the first results is expected for the next SG16 plenary meeting. It was also agreed to work on technical papers collecting ITU-T G.71x and G.72x performance in close collaboration with SG12. Question 9/16 will also work on content for G.718, which will be subsequently provided to Q10/16 for harmonization and integration in the main Technical Paper or Supplement. A Liaison Statement to SG 12 was issued and one interim meeting is planned 6-10 July 2009.

Question 12/16 Summary
Question 12/16 made progress toward the development of requirements and architecture for the new Advanced Multimedia System (AMS). The experts of Q12 reviewed incoming liaison statements, agreed upon new and modified requirements for AMS, and agreed upon revisions to the AMS terminal architecture specification, revisions to the AMS service node specification and updated the AMS working assumptions. We also communicated with other SDOs and ITU-T Study Groups in order to help progress the work and coordinate activities.

Question 13/16 Summary
Question 13/16 reviewed all the contributions and LS statements. We have initiated six new documents and produced in all 21 documents. The roadmap of IPTV standards under SG 16 has been updated. Four draft new Recommendations were Consented: Content delivery error recovery for IPTV services (ITU-T Rec. H.701, ex H.IPTV-CDER), IPTV terminal device: Basic model (ITU-T Rec. H.721, ex H.IPTV-TDES.2), Overview of multimedia application frameworks for IPTV (ITU-T Rec. H.760, ex H.IPTV-MAFR.0) and Nested context language (NCL) and Ginga-NCL for IPTV (ITU-T Rec. H.761, ex H.IPTV-MAFR.9). Various meetings and audio conference calls are planned between February and October 2009.

Question 14/16 Summary
The goal of Question 14/16 at this meeting was to continue the development of Recommendations V.150.1, V.151, V.152 and V.IP2IP-VxF and complete the Draft for new Recommendation V.AMAT. The group made good progress on V.152 and V.IP2IP-VxF but unfortunately no contributions or updated editor drafts were available on V.151 and V.AMAT, so the goals set for consent of these Recommendations were not met. The Rapporteur will encourage renewed effort to complete these Recommendations for the next meeting of SG16.

Question 15/16 Summary
Two contributions and eighteen temporary documents were received in this meeting. One contribution proposes additions/changes to I.733 and the proposal was adopted. Q.15 has the consensus in putting Recommendation ITU-T I.733 forward for consent. Corrigendum 1 to G.763 was Consented and officially approves the defect corrections previously identified in the G.763 Implementors’ Guide. Some updates were made in G.IP2IP. One interim meeting is proposed.

Question 16/16 Summary
Further progress was made in Question 16/16 on drafting text for revised Rec. ITU-T G.168 (Digital network echo cancellers), revised Rec. ITU-T G.160 (Voice enhancement devices) and revised Rec. ITU-T G.169 (Automatic level control devices). Work on revised Appendix II to G.160 covering objective measures for characterizing noise reduction functions also progressed. G.168 was Consented at this meeting. One interim meeting is proposed.

Question 18/16 Summary
At this meeting, Question 18/16 advanced the work on drafting new Recommendation G.MDCSPNE “Mechanism for dynamic coordination of SPNE”, revised Recommendation ITU-T G.161 "Interaction aspects of signal processing network equipment" and new Recommendation G.SPNE “Signal Processing Network Equipment”. One Liaison Statement was sent to IETF, SG 11 and the FG-FITCAR II. The Question plans to hold one interim meeting.

Question 20/16 Summary
Q20/16 reviewed activities related to multimedia coordination, including outcome of recent IPTV-GSI and NGN-GSI Events, participation in the Fully Networked Car Workshop, organization of an e-Health Workshop. It also reviewed progress on Home networking and TDR priority issues. The Question produced an outgoing LS inviting ITU-T, ITU-R and ITU-D study groups to provide representatives for coordination activates connected to multimedia coding, systems and applications.

Question 21/16 Summary
Q.21/16 discussed architecture aspects of home network, particularly resource control functions within and outside home network. Due to proximity to NGN activities, it is agreed to keep close cooperation with SG13. Taking into account recent development of multimedia service applications for NGN environment, the draft text of multimedia architecture for NGN (H.mmarch) is updated. Networked ID including ID resolution protocol, USN and Visual Surveillance are discussed jointly with Q.22/16.

Taking advantage of collocated meeting with SG9, a joint meeting with relevant Questions of ITU-T SG 9 on home network was held. It was agreed to continue this collaboration in the context of Service Delivery Platform and Home Network.

Question 22/16 Summary
At this SG16 meeting, Question 22/16 experts met for 6 sessions including three joint sessions with Q21/16 and one joint session with Q25/16. Technical areas covered were service awareness, NID, USN, visual surveillance. Based on the discussion, F.VSreqs and F.MSATC were updated but they were found not to be mature enough for Consent at this meeting. It was agreed to move F.usn-mw to Q25/16, but joint work by Q22/16 and Q25/16 is be needed until it can be consented. Regarding NID issues, it was concluded after an extensive debate that more contributions are needed to perfect our understanding of some essential issues.

Question 24/16 Summary
Question 24/16 is a new Question. Based on proposals received, a new work item on service awareness and traffic control functional component (“H.SA&TCFC”) was created and an initial skeleton was developed.

Question 25/16 Summary
Question 25/16 is a new Question and considered 18 input documents. It produced eight output documents, including five outgoing LS. In this first meeting, good amount of time was spent to clarify the scope of work and its relationship with other SG 16 Questions, in particular Q22/16, and to define the work program for Q25/16. Contributions are requested to progress all identified work items. It was agreed that while the main responsibility for F.usn-mw is transferred from Q22/16 to Q25/16, both Questions will work together to develop it.

Question 26/16 Summary
Question 26/16 received no contributions to its work but dealt with a number of liaison statements and other information documents. The work programme was revised, adding items on the effects on our work of Resolution 70 and the UN Convention on the Rights of Persons with Disabilities. It was decided to start work on creating a Recommendation in the ITU-T F.700-series on relay services. A joint meeting with Question 4/2 and Question 20/1 (ITU-D) was proposed together with an accessibility event in October/November 2009. Work will continue by correspondence.

Question 27/16 Summary

Updated text for Question 28/16 – Multimedia framework for e-health applications

(Continuation of Question 28/16)


The evolution of advanced digital telecommunication techniques has enabled the development of multimedia systems to support e-health applications, in particular in the area of telemedicine.

E-health designates the use of information and communication technology (ICT) means to support health needs, while telemedicine is considered as that part of e-health where telecommunication systems which allow interconnecting remote locations and to access distant resources. Examples of telemedicine applications are teleconsulting, teleradiology, telesurgery, etc. (See note below for the definitions from the World Health Organization.)

This Question focuses on standardization of multimedia systems to support e-health applications.

In order to allow a wide deployment of e-health applications (with an initial focus on telemedicine applications), in particular in developing countries, it is important to achieve interoperability among systems and to reduce the cost of devices through economies of scale. Consequently, the development of global international standards with the involvement of the major players (governments, inter-governmental organizations, non-governmental organizations, medical institutions, doctors, etc.) is a key factor to achieve these objectives.

Considering the fact that many organisations are already active in this field (with which ITU has existing cooperation agreements) and that, in addition to technical issues, there are a number of other aspect to be considered (e.g. legal, ethical, cultural, economics, regional), it is considered that ITU T can provide the right environment to harmonize and coordinate the development of a set of open global standards for e-health applications.

In the framework of this Question, Study Group 16, as lead study group for multimedia coding, systems and applications, will coordinate the technical standardisation of multimedia systems and capabilities for e-health applications in ITU-T, and will develop corresponding Recommendations.

The improvements and additions to the specific characteristics of multimedia systems and terminals will be addressed within the relevant equipment related questions of Study Group 16.

Note: According to the World Health Organization, telemedicine is “the use of information and communication technology to deliver medical services and information from one location to another", while e-health is “a new term used to describe the combined use of electronic information and communication technology (ICT) in the health sector”.

Study items

Study items to be considered include, but are not limited to:
  • Identification of users' requirements
  • Multimedia framework (including overall concept) for e-health applications (and telemedicine, in particular)
  • Roadmap for e-health (including telemedicine) standards
  • Generic architecture for e-health applications (and telemedicine, in particular)
  • Specific system characteristics for e-health applications (e.g. video and still picture coding, audio coding, security, directory architecture, etc)
  • Considerations on how to help measure and mitigate climate change
  • Creation of glossary of e-health (telemedicine, in particular)
  • Methods for inputting, transmitting and processing data for e-health (telemedicine, in particular)
  • Databases and knowledge-bases of information and expertise on, and technologies for, e-health (telemedicine, in particular) as well as consultants and specialists, and potential customers of e-health (telemedicine, in particular)
  • Mechanism for querying, finding, identifying, and categorizing consultants and customers in the area of e-health (telemedicine, in particular)
  • Personal terminals for e-health (telemedicine, in particular)

Tasks include but are not limited to:
  • Update the inventory of existing e-health / telemedicine standards (2009)
  • Creating and maintaining a high-visibility web page documenting the progress of the question (ongoing)
  • Roadmap for e-health / telemedicine standards, compiling and analysing standardisation requirements from e-health stakeholders and identifying standardisation items with priorities (2009)
  • Support of ITU-D telemedicine activities
  • Provide inputs for extension and improvement of existing Recommendations on multimedia systems (e.g. H.323, H.264, V.18, etc) (ongoing)
