As someone who now regularly watches TV shows on the tube using their N95, and someone who used to own one of those Virgin lobster 'watch live TV' phones I consider myself well experienced with this.

My comments - live broadcast *does* *not* *work* - even if the flakey reception (and non-existent underground reception) was sorted out, the whole point of mobile device TV is that it fits around your idle time on public transport - you press play when you get to the platform - you press pause when you change trains - a broadcast schedule just wouldn't work.

Secondly, I was initially sceptical about the screen size - but it's down to your choice of content - The Simpsons or South Park works perfectly on the N95 screen but I struggle with movies or drama because they're filmed for something much bigger. That's not to say it would only work for cartoons - it's to say that content may have to be specially edited for effective mobile use, with more close-up shots for example.

If DVB-H can trickle-download content for later on-demand viewing then it might be a goer, but those banking on armies of people watching live are throwing their money away, unless the content is going to be live events like sport - and even there, some pause or replay facility would be desirable.
