Complicating the whole mobile TV thing even further, IPWireless has come out with another standard
, known as TDtv. This utilises spectrum that existing European operators already have, and is in direct competition with DVB-H.
It runs in what is known as unpaired TD spectrum and IPWireess already has four European operators already testing the system. One of which is in the UK.
TDtv has got a lot going for it. For starters, it keeps control of the broadcast content firmly in the hands of the network operator. Not a third party.
TDtv is built around MBMS - the TV version of multimedia messaging. Sprint Nextel has invested $10 million in the technology.
