We'd surmise that neither Europe nor the Americas are anywhere close to worrying about a next-generation mobile TV standard, since virtually no carrier has managed to monetize the standards they've already adopted -- but things work a little differently in Japan where one-seg tuners are offered on nearly every portable device with a screen that's sold. A refinement of the existing ISDB-T technology designed to take advantage of the analog TV shutdown, ISDB-Tmm, had been pushed by NTT DoCoMo, while competitor KDDI -- the country's main CDMA operator -- had wanted to adopt Qualcomm's MediaFLO in a regulatory decision originally scheduled to be made by the middle of this month, but the government has apparently decided to hold off in the hopes that the two sides can work together on a mutually beneficial standard. Commercial availability of the network had been expected in 2012, so it'll be interesting to see if these two giants can bury the hatchets long enough to work this out.
