Future of mobile TV

Some modern mobile phones have the capability of receiving Mobile TV signal (DVB-H, to be exact). In Finland, Digita Oy launched DVB-H mobile TV network rather recently and the network covers nowadays something like 40% of the Finnish population. Some of the Finnish media houses are broadcasting their (regular) TV and radio-programmes to DVB-H network. Would all this mean that people are going to watch TV on their mobile phones?

Personally, I think that DVB-H has rather slim chances to actually make it. There are many things which make the success of DVB-H questionable.

1) why would you watch TV on your mobile?
I haven't been able to figure it out myself. I haven't seen a single (public) consumer survey according to which mobile TV would have been seen as something that people are willing to pay. Apparently, Nokia's studies haven't identified DVB-H chip as something important as they haven't been promoting mobile TV anyhow (compare to camera / navigation).

2) if you wanted to watch TV on your mobile, why not picking DVB-T signal instead?
Some people have told me that DVB-H is definitely needed, if you want to put TV on a mobile phone. There are several arguments:
* DVB-H uses MPEG4, which offers compression superior to MPEG2 in DBV-T. This makes DVB-H much more battery-friendly
* DVB-H uses higher frequency, which makes the signal more suited to urban environment. You can pick the TV signal even inside buildings

I understand enough about computer science and physics to realise that both arguments are valid. It is propably impossible to develop a mobile phone with integrated DVB-T-receiver that would have decent battery-life - at least today. But would it be possible that in the future microchips used in mobile phones would be able to decode MPEG2 so effectively that they would not need that much power? Or maybe it becomes possible to manufacture batteries that can hold 100 times more energy than today?

3) Is there content for mobile TV?
Or is it the regular TV content that would be used on mobile TV? Today, mobile TV is sending the same programme as the regular TV. I wonder if this is going to be the use for DVB-H?

No matter what the content eventually will be, one thing is sure: there will be lots of negotiations (read fights) between mobile TV-broadcasters and those from whom they are licensing the content. Producers want more money for their content as it is being now distributed in a new channel: mobile-TV. Obviously, TV-broadcasters argue that it is NOT a new channel, so they don't have to pay extra money for the rights.

Before those licensing problems are solved, and DVB-H becomes business-compatible for all the involved parties, I am sure that quite many of us are already watching DVB-T on our mobile phones.
