Q.A/16 (MediaCom 2004) [WP4] There was no specific activity on Question A/16 at this meeting. Work will continue by correspondence. It has been noted that the overall coordination activities in the area of E-health will be addressed in the framework of the Mediacom 2004 project.

Q.B/16 (Multimedia Architecture) [WP4] Question B considered the draft of H.610 (ex H.fsv-arch) and incorporated comments from the Editor and the committee.  Consensus was reached on the comments and the revised draft Recommendation was Consented by SG 16.

In addition, a draft new Supplement 3 to the H-Series on H.610 and H.611 (ex H.fsv-oamp) containing operator requirements, previously being considered in Q.C, was transferred to QB. The work on the text was completed and Supplement 3 was approved by the SG 16 Plenary.

The meeting drafted and accepted a new Work Item  (“Distributed Application Layer Architecture for Provisioning, Management and Support of IP based Services, including Multimedia, over DSL Networks”) to focus the further work of the group and encourage future contributions on this subject. Comments made in the SG 16 Plenary suggested that this work item should be transport network independent.

Q.C/16 (Multimedia applications and services) [WP4]
  • Question C/16 considered the draft of H.611 (ex H.fsv-oamp) and incorporated comments from the Editor. Consensus was reach on the comments and the revised draft Recommendation was Consented by SG 16.
  • The meeting drafted and accepted the baseline draft for a Metadata Recommendation. 
  • The Rapporteur expressed his concern that there continues to be a lack of contribution on E-Commerce/E-Business. He once again encouraged contributions on that subject.
  • The work on draft Recommendation F.706 was transferred to Question I/16 by the opening SG 16 Plenary, and results can be seen in the summary for Q.I, below.
Q.D/16 (Interoperability of Multimedia Systems and Services) [WP2]

No particular sessions were held on Q.D/16. All documents addressed to Question D were addressed jointly to and discussed in related WP2 questions.

Q.E/16 (Media coding) [WP3]
  • Draft new Annex B/G.726 and draft new amendments 1 and 2 to T.88 were Consented
  • Q.E revised and updated the Media Coding Summary Database in Annex Q.E.1 of TD-12 (WP3/16).
Q.F/16 (Quality of Service and End-to-end Performance in Multimedia Systems) [WP2]

Progress was made on H.QoS.Arch and additions to H.460.9 (in conjunction with Q.2/16). Co-ordination with other groups was progressed in a number of important areas via liaisons.

Q.G/16 (Security of Multimedia Systems and Services) [WP2]
  • Question G “Multimedia Security” reached an important milestone: Consent of revised recommendation H.235v3 providing several important new security features and corrections.
  • Corrigenda were also Consented to ITU-T Rec. H.235 Annex F and ITU-T Rec. H.530.
  • Good progress made on the other active drafts for H.235 Annex H and H.235 Annex G.
  • Reviewed and cleaned up the work plan of Q.G.

Q.H/16 (Accessibility to Multimedia Systems and Services) [WP1]

During this Q.H/16 Rapporteur meeting the following two baseline documents were considered:
  • Total Conversation and Text Telephony Implementation guidelines and profiles (TD16/WP1), and
  • Requirements specification for PSTN type text telephony transit through IP networks (TD17rev.1/WP1).
The following two activities are planned for the “Accessibility” workshop:
  • TDI (Telecommunication for the Deaf, Inc.) workshop in Las Vegas, Nevada, 15 July 2003: ITU-T SG16 will organise a workshop on ITU Takes Deaf People's Accessibility Needs Into Account (Moderator: Andrea J. Saks (Advisor to U.S. Department of State on accessibility for ITU-T Telecommunications Standards),
  • Accessibility Workshop in Geneva, 17 October 2003: the outline was considered and the overview will be announced in the ITU-T website.

Q.I/16 (Use of public telecommunication services for emergency and disaster relief operations) [WP4]

Q.I/16 considered the next steps for the establishment of the TDR Partnership Coordination Panel (PCP). The following actions were agreed to:

  • email will be sent to TDR participants informing the availability of the final report and the establishment of the PCP
  • establish initial contact with potential PCP members. A list of initial names was prepared at the meeting.
  • A TSB Circular Letter will be prepared informing on this action. A base text was prepared at the meeting.
Responsibility for F.706 was transferred from Q.C to Q.I at this meeting. After discussions, it was decided to split F.706 in two texts. What remains in F.706 will contain a high level description of a preference scheme for multimedia (as found in TD 16/WP4). The draft version of the new document, labelled F.MMCTDR (Multimedia Concept to Support TDR), is found in TD 19/WP4.

The question also addressed the responses received to the TDR Questionnaire issued in TSB Circular 132. TD12R1/WP4 contains the synopsis and updated matrix of the responses to the Circular. The results were difficult to interpret and reflect a wide range of understandings for the TDR work. It was the feeling of the Q.I/16 that it needs to be made clear that the TDR work covers international communications of authority-to-authority (i.e., authorized user) not citizen-to-authority or authority-to-citizen.

Q.1/16 (Multimedia systems, terminals and data conferencing) [WP2]

Question 1 was successful in completing the work on signalling requirements for H.264 in H.300-series terminals (H.241), and on role management and additional media channels in H.300-series terminals (H.239). Four new texts under the responsibility of Q.1 (ITU-T Recs. H.241, H.239, H.350.3, H.222.0 Amd. 2), plus one corrigendum to H.222.0, were Consented at this meeting (see below). An Implementer’s Guide for the H.320 series was also approved, superseding the previously existing one (2002-02).

Q.2/16 (Multimedia over packet networks using H.323 systems) [WP2]

Question 2 successfully completed work on revised Recommendations H.323v5 and H.225.0v5.  These revised recommendations bring a number of various enhancements to H.323. Question 2 also successfully completed work on new Recommendation Annex O/H.323, which describes the use of DNS and H.323 URLs within H.323 systems.  Also completed at this meeting is a new Appendix to H.460.1, which documents the identifiers that are allocated for the various features that are implemented via the Generic Extensibility Framework (GEF).  We also worked with cooperation of Working Party 3 to complete a new Annex to G.726 that will allow H.323 systems to signal G.726 within the context of an H.323 system.

Additionally, a revised version of the H.323 system Implementer’s Guide was approved, superseding the earlier version approved in 2002-10.

Several new work items were started at this meeting, bringing the total number of work items in progress within Question 2 to eleven. Lastly, the meeting reviewed several contributions on various topics that may result in the creation of new work items at the next Rapporteurs meeting.

Q.3/16 (Infrastructure and interoperability for Multimedia over packet networks) [WP2]

Q.3/16 was successful in completing the work on H.239, H.241, H.245v10, H.246 Annex Cv2, H.248.22-27, which were Consented by SG 16. Q.3/16 also completed work on the H.248 Implementors' Guide and the H-series Supplement 2: H.248 Packages Guide and on a revised version of the H.248 sub-series Implementer’s Guide (which supersedes the earlier version approved in 2002-10). Both texts were approved by the SG 16 Plenary.

Q.4/16 (Video and data conferencing using Internet-supported services) [WP2]

Question 4/16 successfully completed the work on 6 Recommendations of the H.350 series that describe a Directory Services architecture for multimedia conferencing using LDAP. Directory services can provide automated configuration of endpoints, association of persons with endpoints, searchable white pages, clickable dialling, and user authentication based on authoritative data sources. H.350 describes a standardized LDAP schema to represent endpoints on the network and associate those endpoints with users. H.350.x Recommendations describe specific subclasses, derived from the base H.350 architecture, which represent specific protocols. These texts, H.350, H.350.1, H.350.2, H.350.3, H.350.4, and H.350.5, were Consented by SG 16.

Q.5/16 (Mobility for Multimedia Systems and Services) [WP2]

Q.5/16 work items are currently on hold due to lack of editors and contributions.

Q.6/16 (Advanced video coding) [WP3]

The AAP last call comments on Rec. H.264 were addressed in the jointly-collaborative environment of the ITU-T SG 16 and ISO/IEC SC29/WG11 Joint Video Team (JVT) with the results reflected in the draft text submitted for Decision by SG16 as TD 66 (P). Q.6/16 believes all significant concerns raised in the last call process were addressed, and the parties submitting comments participated in the work of the JVT and appear fully satisfied with the result.  The changes agreed to address the comments were minor, directed toward ensuring clear and correct editorial expression of the previously-established technical intent. Q.6/16 considers the submitted Draft New Recommendation H.264 to be stable and to be supported by industry and therefore ready for Decision by SG16.

The work of the JVT, including results of the co-located JVT meeting, which was held during this meeting of Study Group 16, was discussed.  Support was expressed for the ongoing work on conformance, reference software, bitstream exchange, and verification testing for H.264. Support was also expressed for continuation of the JVT organization and endorsing future activities by the JVT toward specification of an amendment or annex to Rec. H.264 supporting professional applications, targeting primarily support of greater sample precision and increased chroma sampling resolution.

Q.7/16 (Wideband coding of speech at around 16 kbit/s) [WP3]

The main objective of the meeting was to review updates to the G.722.2 specifications (Wideband speech coding at around 16 kbit/s, which is aligned with the 3GPP AMR-WB specification). Proposed changes were approved and it was decided to issue a new revision of G.722.2, in order to keep the alignment between the 3GPP and ITU-T versions of the specification.

Q.8/16 (Encoding of speech signals at bit rates around 4 kbit/s) [WP3]

As agreed at the October 2002 meeting of SG16, work on Question 8/16 has been suspended. Consequently there was no discussion on this topic.

Q.9/16 (Variable bit rate coding of speech signals) [WP3] The main objectives of the Q.9/16 meeting were to finalize the Terms of References (ToRs) for both MSC-VBR approach and EV approach. Through the intensive review of ToRs reflecting reply LS comments from 3GPP, 3GPP2 and the proposals made through input contributions, MSC-VBR TorR was agreed to include Wideband speech capabilities and EV ToR was also agreed to include wider-bandwidth extension as a future Annex. As the results, ToRs were revised especially on newly agreed capabilities but many aspects were left open for further discussions. Liaison Statements to other bodies asking their comments on the preferable features were drafted. One interim meeting was planned in October to advance the work on drafting ToRs.

Q.10/16 (Software tools for signal processing standardization activities and maintenance of existing voice coding standards) [WP3]

As regards the Maintenance aspects of the question, one delayed contribution and two temporary documents have been submitted to Q.10 at this meeting. Problems in G728 annex J recommendation have also been reported by emails. The group reviewed the proposed corrections to G.722 (COM6-D313) and agreed to prepare an erratum to ITU-T Rec. G.722. TD 69 (G) that proposed an annex B to G.726 dealing with "Packet format, capability identifier, and capability parameters for H.245 Signalling" was jointly discussed with Q2, 3 and E; the final Consented version is found in TD 77 (P) for consent. The issue addressed in TD 30 (G) was clarified before the meeting.

As regards Software Tools aspects of the question, one delayed contribution has been submitted to Q.10 at this meeting. COM16-D297 proposes to extend the current 32-bit basic operators by including additional 40﷓bit basic operations. The group considered that more inputs/discussions were required and agreed to work by email correspondence using the WP3 audio email reflector

No interim meeting is planned, Q.10/16 will continue its work by correspondence on the following items: preparation of corrigenda and corrected versions of the attached software and test vectors to start formal approval of changes at the next Study Group 16 meeting from the IG on existing voice coding recommendations, release of STL2004, basic operators sets review.

Q.11/16 (Voiceband Modems: Specification and Performance Evaluation) [WP1]

Q11 and Q13 met jointly and have agreed to create a draft corrigendum for corrections to V.92, V.150.1 and V.250. The group also agreed to create a new Recommendation for voice band data only gateways. Work is progressing on V.ToIP per schedule. A request is being made for the TSB to consolidate V.250 and to publish it as the 2003 Revision. Corrigenda were Consented for V.92 and V.150.1, as well as an Amendment to V.250 (see below).

Q.12/16 (DCE-DCE Protocols for the PSTN and ISDN)

There was very little business this time; the only activity was to prepare the text of a corrigendum to Recommendation V.42 correcting some minor errors, which was approved for Consent by the SG 16 Plenary.

Q 13/16 (DTE-DCE Interfaces and Protocols) [WP1]

Q.13/16 met jointly with Q.11. See report above.

Q.14/16 (Facsimile terminals of Groups 3 and 4) [WP1]

Q.14 worked on a corrigendum to clarify syntax usage with respect to the revision level and an Amendment to T.38 and for the addition of V.34 half-duplex facsimile, both items having been Consented at this meeting.  Also work was completed on Amendments to T.4, T.30 and a revision of T.42 for the addition of YCC display oriented colour space to facsimile terminals; which were also Consented by SG 16. A corrigendum to properly define the extension bits in T.30 was also Consented.  A new proposal to add RTP to T.38 was reviewed with an agreed goal of approval in January 2004.  The status of the work for any planned Interim meetings was discussed with the agreement that tentatively one may be required.  The group will continue to work by electronic correspondence using the ITU-T Q.14 reflector (

Q.15/16 (Distributed Speech Recognition and Distributed Speaker Verification) [WP3]

There were no contribution addressed to Question 15/16, and consequently there was no discussion on this subject. More contributions are encouraged to future meetings of SG16.

Draft text of a new question on E-health in SG 16

The following is an extract from TD 63/Plen:

Title: Q J/16 - Multimedia framework for E-Health applications

Background and Justification

The evolution of advanced digital telecommunication techniques has enabled the development of MM-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 care needs, while Telemedicine is considered as that part of E-health where telecommunication systems allow interconnecting remote locations and to access distant resources. Examples of Telemedicine applications are teleconsulting, teleradiology, telesurgery, etc.

Within the general concept of E-health, this question focus on standardization of Multimedia Systems to support Telemedicine applications

In order to allow a wide deployment of Telemedicine applications for the benefits of the market, in particular in developing countries, it is important to achieve interoperability among systems and to reduce the cost of devices through economy 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 already cooperate 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 can provide the right environment to harmonize and coordinate the development of a set of global standards for E-health applications.

In the framework of this generic question, SG16, as lead SG for Multimedia Applications and Services, will coordinate the technical standardisation of Multimedia systems and capabilities for Telemedicine applications in ITU-T and will develop corresponding Recommendations.

The improvements and additions to the specific characteristics of MM-systems and terminals will be addressed within the relevant equipment related questions of the SG.

Study items
  • Multimedia framework for Telemedicine applications
  • Identification of users' requirements
  • Roadmap for Telemedicine standards
  • Generic Architecture for Telemedicine applications
  • Specific system characteristics for Telemedicine applications (e.g. video and still picture coding, security, directory architecture, etc)
Specific task objectives with expected timeframes for completion

  • Inventory of Telemedicine regional and proprietary standards:
  • Identify standardisation items with priorities: 
  • Develop a Recommendation “Generic Architecture for Multimedia Telemedicine Applications”:
  • Extend and improve existing Recommendations on MM-Systems (e.g. H.323, H.264, V18,...):
  • Develop new Recommendations if necessary

Relationship of this study activity to other groups:

  • Recommendations: H.323, H.264, V.18, others TDB
  • Questions: A/16, B/16, C/16, D/16, E/16, F/16, G/16, H/16, I/16, 1/16, 2/16, 3/16, 4/16, 5/16, 6/16
