"Some commentators are sceptical about the cost of the services, the handsets or content. There may also be a factor in the incompatible expectations of broadcasters and mobile operators. Traditional PSB and commercial broadcasters are used to a free to air business model with network costs under their own control and are naturally concerned when telecoms operators control their access to a Mobile TV platform. Meanwhile Telecoms operators require a subscription model with many channels under their control and, inevitably, much higher network costs. If there is any discernible pattern emerging, it could be that DMB is more suited to broadcaster controlled, low cost, free to air models whilst DVB-H is finding favour as a telecoms operated subscription network."

So logically, DMB broadcasters will require receivers that they can control as well. That's already the case for most receivers on the market right now but it could get tricky for converged devices which are mostly under telco control today.
