    Technology Retreat 2006

    Thank you, Mark for the opportunity to talk about this new and exciting new sector as part of the worldwide digital television industry.

    I have been involved in Mobile DTV for all of about 10 months now. I have quite a history with DVB-H as I am the principal project engineer and designed and implemented the first (and only) DVB-H broadcast center in North America. So based on my rich and broad background in this new market, I will be presenting a high level perspective of the Mobile TV market space, the various technologies competing, and some specifics regarding the Modeo Mobile TV broadcast network.

    Given the hour time period, this presentation will essentially fly-by this up and coming digital television sector.

    The topics covered today include a brief introduction to the Mobile TV market and perhaps try and answer a question or two as to why?, and how?, or what?. [more here]

    There is tremendous mobile TV trial activity through the world, with competing broadcast technologies. I will introduce various mobile TV broadcast technology group, and try to differentiate these groups highlighting benefits and disadvantages.

    IMG Internet Media GuidesMUPPET - a unidirectional point-to-multipoint transport protocol for the delivery of Internet Media Guide metadata. The MUPPET protocol is based on Asynchronous Layered Coding (ALC), a massively scalable protocol for reliable multicast transport. MUPPET is intended to be used with the Internet Media Guide framework, and in addition may be useful with other applications.
