There’s probably a lifetime of things to say about ordinary life in London in the few days since my last posting - but there’s not enough room here to go through them all - and for this I apologise. (Actually this is a lame excuse for not taking enough pictures to tell a story around recently!)

But there are some things that possibly verge on being so remarkable that are simply worth capturing and sharing at this particularly geeky stage of development. And one of them is “Mobile Interactive TV”.

Yesterday - one of my friends wheeled in a couple of hi-tech “boxes” and rigged them up to a standard set-top TV aerial/antenna like the kind you get in Argos or Dixons. He twiddled around with a few of the knobs, buttons and dials on the boxes, pushed the “broadcast” button - and proudly announced that he had just set up his own “TV station”. He then walked away a few metres - and pulled a strange-looking mobile phone out of his jacket and “tuned” it in to the signal being broadcast from his makeshift “TV station”.

And hey presto: he was watching a “home-made” TV channel between the palms of his hands.

It all looked too easy. When I asked him how it worked - he said “This is DVB-H - digital broadcast TV for mobile phones!“

Not video-streaming. Not fuzzy, blurry pictures. Not cabled up to an aerial or a set-top box.

Just a crystal-clear, high-definition, wireless broadcast TV channel. The fact that it was being viewed on a mobile phone implied that the GPRS/3G capability of the phone could be used as the “uplink” to the TV station over the Internet. Fuelling the imagination into thinking about lots of possibilities in the field of mobile interactive TV broadcasting. But more importantly - demonstrating the possibility of using short-range radio spectrum to provide localised (and location-relevant) interactive TV applications.
