Scenarios and Usecases of Mobile IPTV
ITU-T Y.miptv-scen: Scenarios and Usecases of Mobile IPTV
Established as a New Work Item by Q.14/13 in April 2010
Developed an initial baseline text at Q.14/13 Rapporteur Meeting
(July 2010, Seoul)
based on Appendix of H.IPTV-TDES.4 developing by
ITU-T Q.13/16
Several Usecases and Scenarios have been modified and added
Updated text of Y.miptv-scen (NGN-GSI, )
Updated text of Y.miptv-scen (Q.14/13 Rapporteur meeting, )

4. Standardization Activities on Mobile IPTV in ITU-T (2/5)
Functional Requirements of Mobile IPTV
ITU-T Y.miptv-req: Functional Requirements of Mobile IPTV
Established as a New Work Item by Q.3/13 in April 2010
Developed a baseline text at Q.3/13 Rapporteur Meeting
(July 2010, Dalian)
Updated text of Y.miptv-req (Sept. 2010)
Discussed with delegate from ATIS
ATIS started standardization work on mIPTV issues
ATIS will submit contributions on mIPTV issues to the
next NGN-GSI meeting (Jan. 2011)

Requirements of Mobile IPTV (Sept. 2010)

6. Standardization Activities on Mobile IPTV in ITU-T (4/5)
Mobile IPTV Terminal Device
ITU-T H.IPTV-TDES.4: IPTV Terminal Device and End System
(Mobile Model)
Developing by Q.13/16
Current Contents of H.IPTV-TDES.4
Functional Architecture of IPTV Terminal Device
General Overview of Mobility
Specific Requirements for Mobile Terminal
Capabilities and Protocols for mobile IPTV Terminal Device
Interfaces for mobile IPTV Terminal Device
Appendix I: General Requirements for mobile IPTV services
Appendix II: Example Use cases and Service Scenarios

7. Standardization Activities on Mobile IPTV in ITU-T (5/5)
Security for Mobile IPTV
X.iptvsec-6: Framework for downloadable SCP system in
mobile IPTV environment
Established a New Work Item in ITU-T Q.6/17 in March 2010
Very much initial stage

8. Current Issues of mIPTV Standardization
What is the Mobile IPTV ?
ITU-T Definition of IPTV [Y.1910]
Multimedia services such as television, video, audio, text,
graphics, data delivered over IP-based networks managed
to support the required level of QoS/QoE, security,
interactivity and reliability
Current Definition of mIPTV (temporally used in Y.miptv-req)
Multimdia services such as television, video, audio, text,
graphics, data delivered over IP-based wireless/wired
networks managed to support the required level of QoS/QoE,
mobility, security, interactivity and reliability.
Do we need additional definition on mIPTV?
Y.1910(IPTV Architecture) covers mIPTV or not ?

9. Current Issues of mIPTV Standardization
How to describe mIPTV Requirements in relevant
documents ?
Y.1901 describes general requirements of IPTV including mIPTV
Y.miptv-req describes functional requirements for different
aspects of mobile IPTV
H.IPTV-TDES.4 describes specific requirements for mobile terminal
X.iptvsec-6 may describe security requirements for mobile IPTV
Current direction of Y.miptv-req to describe requirements
for each requirement, it is generally required to clarify
if it is specific to Mobile IPTV or not
Requirements of IPTV already described in relevant approved
ITU-T documents (e.g. Y.1901, etc.) need to be referenced
rather than described again

10. Current Issues of mIPTV Standardization
Relationship of mIPTV Usecases and Scenarios
between Y.miptv-scen and H.IPTV-TDES.4 ?
H.IPTV-TDES.4 describes Appendix to describe several Usecases
and Scenarios for mobile IPTV
Y.miptv-scen was developed based on Appendix of H.IPTV-TDES.4
but it is extended to describe more Usecases
How to deal with the relationship of these two documents in the
future.
Necessity of further Recommendations for mIPTV
Architecture and Framework for mIPTV to provide overall
technical aspects and functional interactions among different
functional components to realize Mobile IPTV
Protocols and Mechanisms for Mobile IPTV

11. Future CJK Collaboration for Mobile IPTV Standardization
We need contributions from CJK members to develop relevant Draft Recommendations
Korea will submit contributions based on our experience on mIPTV over WiBro mobile network environment
Are there any trials or experiences on mIPTV in CJK ?
Need close Collaboration among CJK members for Harmonization and rapid progression of current mIPTV Recommendations
Collaboration and Coordination with other relevant
SDOs should be considered to realize mIPTV
ATIS may actively participate in mIPTV standardization work from the next NGN-GSI meeting
