  • 4. Outlook on Mobile IPTV - Definition /25 SOC 컨퍼런스 2008 Mobile IPTV is a technology that enables users to transmit and receive multimedia traffic including television signal, video, audio, text and graphic services through IP-based the wired and wireless networks with support for QoS/QoE, security, mobility, and interactive functions. Through Mobile IPTV, users can enjoy IPTV services anywhere and even while on the move.
  • 5. Outlook on Mobile IPTV - Approaches IPTV Mobility Mobile TV IP Access network is agnostic /25 (WLAN, WiMAX, Celluar) (DMB, DVB, MediaFLO)

    • IP Radio characteristics
    • KBS Kong, MBC mini, etc…
    • In Home and Office
    • Video services
    • anywhere on earth (IP networks)
    • interactive services
    • new services (winding, recording)
    Outlook on Mobile IPTV – IP Radio /25
    • IP Radio came up

  • 10. Outlook on Mobile IPTV - Contents To Live or Die by CONTENTS
    • User Requirements
    • Less 30 minutes a day
    • Increasing on trip
    • Easy Control (TV likely)
    • TV Usage in Everywhere
    • Lightweight Contents

    • Mobile TV: How to use ?
  • 11. Technical Issues Around Mobile IPTV – Wireless and Mobile
    • Changeable bandwidth
    • Vulnerable wireless link
    • Weak security chain
    • SD/HD contents delivery
    • Middleware
    • EPG
    • Fixed-Mobile Convergence
    • IMS for media streaming
    • Unexpected movement
    • Restricted device capability

  • 12. Technical Issues Around Mobile IPTV – Web
    • Video on the Web
    • User Interface
    • Recommendation according to user profile
    • In-Time UCC
    • Quick Propagation
    /25 Infinite Resources on the Web
  • 13. Mobile IPTV Ongoing Standards – ITU-T /25
  • 14. Mobile IPTV Ongoing Standards – ITU-T Wireless network characteristics: The characteristics of a wireless network expressed in terms of current available bandwidth, packet loss and possibly other to-be-defined wireless network information parameters for a specific wireless link type e.g. WLAN, Cellular, WPAN or WMAN. The IPTV architecture is recommended to allow the delivery of IPTV services over different access networks (e.g. cable, optical, xDSL, wireless) The IPTV architecture is recommended to allow the delivery of IPTV services to any IPTV terminal device (e.g. mobile phone, PDA, set-top-box). The IPTV architecture is recommended to adapt dynamically to change in wireless networks characteristics when the service is delivered over a mobile network (e.g. bandwidth, packet loss rate, etc. The IPTV architecture is recommended to support device mobility that allows a mobile device to maintain its ongoing IPTV services while freely moving around. The IPTV architecture is recommended to support content delivery in several yet optional versions to be selected according to the capabilities of the IPTV terminal device receiving the content (e.g. access rate, resolution, supported formats, etc.). /25
  • 15. Mobile IPTV Ongoing Standards – ITU-T The IPTV architecture is recommended to support the ability to identify wireless network characteristics information sent by the IPTV Terminal. The mobile IPTV terminal device is recommended to support service continuity. The mobile IPTV terminal device is recommended to be able to extract its own wireless network characteristics from the current wireless network. In case an IPTV TD is mobile, it is recommended to support mobility functionalities for service continuity when in motion. An optional signaling architecture for exchanging wireless network characteristics between an IPTV TD (mobile device) and DNG (or Service Provider Server). It allows DNG (or Service Provider Server) to adjust their sending rate for ongoing video service according to the received information (e.g., bandwidth, packet loss, etc.) from the IPTV TD. Piggybacking the information on the existing IP based Protocol is available. /25
  • 16. Mobile IPTV Ongoing Standards – QoS Mobility
    • MPEG Scalable Video Coding
    • Fatting down MPEG frame (P, B)
    • Pulling out link characteristics by IEEE 802.21
    • TCP Quick-Adjust vs. Quick Start
    • Link Characteristic Information for Mobility
    /25
  • 17. Mobile IPTV Ongoing Standards – QoS Mobility
    • Signaling architecture for exchanging wireless network characteristics dynamically
    • Piggybacking these information on the exiting IP based protocols
    RTP (Real-time Transport Protocol) DCCP (Datagram Congestion Control Protocol) /25
  • 18. Mobile IPTV Ongoing Standards – TCP Quick Start
    • Allowing end nodes to request for using a higher sending rate that the normal
    • congestion control algorithm, when the network capacity is under utilized
    • 10 or 100 or larger ?
    /25 Host A one segment RTT Host B time two segments four segments t Data Rate Data Rate t
  • 19. Mobile IPTV Ongoing Standards – TCP Quick Adjust Why QA not QS :
    • Difficult to determine a reasonable rate
    • QS only supports quickly increasing the rate (not decreasing)
    • QS does not have knowledge about the utilization situation of non-IP queues downstream (e.g., AP)
    Reference: http://www.watersprings.org/pub/id/draft-daniel-mip-link-characteristic-02.txt /25 t Data Rate
  • 20. Mobile IPTV Ongoing Standards – OMA BCAST Reference. Mobile TV Standardization in 3GPP & OMA by Markus Kampmann, Ericsson
    • Defines a common service layer for Mobile TV that can be used across different mobile distribution systems
    • Will allows to offer interactive Mobile TV services over multiple radio technologies (DVB-H, 3G)
    • Everything over IP (except codecs)
    /25
  • 21. Mobile IPTV Ongoing Standards – 3GPP MBMS MBMS: Multimedia Broadcast/Multicast Service Reference: Mobile TV Standardization in 3GPP & OMA by Markus Kampmann, Ericsson
    • Required resources depend on number of
    • users
    • Does not scale for larger numbers of
    • simultaneous users
    • Considerable resource savings in CN
    • and RAN
    • Number of content channels
    • determines required radio resources
    BCMCS: BroadCast and MultiCast Service @ 3GPP2 BM-SC: Broadcast Multicast Service Center /25
  • 22. Mobile IPTV Ongoing Standards – DVB CBMS CBMS: Convergence of Broadcast and Mobile Service (DVB-H) /25
  • 23. Mobile IPTV Ongoing Standards – WiMAX MBS
    • The Multicast Broadcast Service (MCBCS) feature refers to network’s ability
    • to provide flexible and efficient mechanisms of sending common (the
    • same) information content to multiple users using shared radio resources
    /25
  • 24. Mobile IPTV Ongoing Standards - TTA Protocol
    • Requirements Classification (Phase I, II)
    • Input to related international STDs
