         What is Mobile TV?

          Mobile  Television refers to constant
           TV being provided on mobile
           terminals and not video downloads.
          It can be offered in the following two
           modes
                   UnicastMode
                   Broadcast Mode

                              MET Alumni Day
         Problems with Unicast Mode
            A new direct video stream has to be initiated for
             each user.
            This is obviously an inefficient method as it tends
             to be a waste of the spectrum.
            Television commands very high bandwidth and
             this places constraints on the capacity that a
             network has to offer
            The current networks do not have the capacity to
             provide Mobile TV to many users concurrently.
         Hence we need Broadcast Mobile TV technologies for mass
         deployment of the service.

         Cellular Vs Non-Cellular

            The addressable market for Mobile TV is not
             limited to current Mobile network operators.
            Laptops, Video Cameras and other portable media
             devices, such as the Sony PSP, represent strong
             niche device, However, the relatively limited
             volumes in which these are shipped when
             compared to Mobile phones, present problems for
             the development of a sustainable commercial
             service.

         Technology Comparison – 2
           The three technologies are similar in most ways
            but are not completely the same.
           Qualcomm’s MediaFLO has an edge over the
            other two.
                 Better Channel Switching Time
                 The main disadvantage - proprietary nature.
           For DVB-H the most suitable spectrum is in the
            UHF frequency range
                 but UHF is currently being used by the analog
                  television services.
                 The DVB-H technology is mainly being promoted by
                  Nokia and is likely to dominate the European Market.

         Technology Comparison – 3
           DVB-H in US and Canada
                 In the US, Crown Castle (Modeo) and Aloha partners
                  (Hiwire) are expected to launch DVB-H services by
                  end of 2006.
                 In Canada, Look Communications has done a DVB-H
                  trial in the spectrum range of 2.5 GHz.
                      Lack of Handsets for this spectrum
           DMB services were the first broadcast mobile TV
            services to be launched.
                 Very Low data rates when compared to the other two
                 South Korea has implemented both the T-DMB and S-
                  DMB networks.
                 T-DMB is free to air service in South Korea

         Canadian Regulation Study

            CRTC ruling in April 2006 exempts the mobile
             TV services from broadcasting regulations.
            This is a boost for the adoption of mobile TV
             services in Canada as more popular programs can
             now be shown and this will help increase the
             subscriber numbers.
            Industry Canada is expected to follow a similar
             process as the U.S. in developing commercial
             operations in the 700 MHz spectrum.

         Conclusions
            Mobile TV Technologies will be adopted regionally
            The Value chain analysis shows that the telecom service
             providers will have to share the revenues with the
             broadcasters.
            UHF Spectrum in Canada will be recovered in the next
             one year.
            The pricing for mobile TV should be a monthly
             subscription fee between US$ 10-15 which would help
             recover the cost in a five year period.
            Major sporting events such as FIFA world cup attract
             many customers.

         Implementing WS in IMS – Conclusions

            IT and Telecom convergence.
            Standards are making these industries to Integrate (IMS,
             Protocols, Web Services, APIs, Java standards).
            JSLEE and Parlay/OSA have a bigger advantage over
             other APIs to enable the creation of applications that
             incorporate telephony and IT services.
            JAIN and Parlay enable new opportunities for new entrants
             to enter the market.
            New applications will incorporate applications and
             services combining IT and telephony services primarily but
             in the future we will see applications that include voice,
             video, data, personalization, presence and policies.

          Comparison of Parlay-X and ECMA-348 (1/2)
                                  Findings of Non-functional Comparison

        Motivation:
         •        Both standards are to expose communication capacities
                  through Web Service.
         •        Both standards are to enable more developers without
                  deep knowledge about communication to develop
                  communication enabled business application


        Adoption:
         •        Some multimedia client software support Parlay-X
                  (IBM), some support ECMA-348 (Microsoft)



August 24, 2006                                                      106

        Comparison of Parlay-X and ECMA-348 (2/2)
         Functional Comparison

        • The comparison is structured in three layers:
                 Classes Comparison;
                 Operational Models;
                 Operation Comparison and Mapping
                  discussion


    Conclusion: most telephony features defined in Parlay-X can be
    mapped to features defined in ECMA-348 directly or indirectly

             What is Unified Messaging?
            Unified Messaging is a telecommunications
            technology that brings together Voice Mail, Fax,
            and E-mail to allow users to access from unified
            interfaces.

            Problems the Project Tried to Solve

          Extend Unified Messaging to wireless devices
                  Not only listen to messages by making phone call, but also download
                  Messages and playback or display on the handheld devices
          Integrate with Instant Messaging
                  Concept of UM has evolved, Instant Messaging is being added

              Follow-up Work

            A study on unified communications
             strategies and solutions might be interesting
             and may better explain the competition
             among big vendors
