This is despite the fact that operators O2, Orange, 3 and Vodafone are investing heavily in the newest ruse to increase our monthly payments, while the BBC, ITV and Sky see live mobile TV as the new frontier for squeezing extra viewing minutes out of us each day.

On paper, mobile TV is an operator's dream: it makes each one of the millions of subscribers nationwide a potential premium customer every time there's a big sporting event, a major news story or even just a spare five minutes.

Unlike most technology breakthroughs, this particular one seems to be coming sooner than most people anticipated. But with the World Cup drawing attention to the mobile industry, dazzling new designs being launched in Asia and constant talk of the new
frontier for broadcasting, are we being hoodwinked by headlines promising a technology that's actually years away from being ready for the mainstream?

Well, some people are already viewing TV on their mobiles. Orange and Vodafone have been offering a live mobile TV service of sorts for months, while O2 has been testing one on a limited scale for some time and is claiming positive results.

More than 80 per cent of the guinea pigs on O2's Oxford trials said they were at least satisfied with the service, while more than 70 per cent said they'd be willing to take up the full service within one year of its prospective launch (although O2 neglected to mention the price the trialists would be willing to pay).

The operator also offered some interesting statistics concerning usage patterns: it was no surprise that, over the course of the trial, 37 per cent of the mobile TV minutes were consumed during the commute to work.

But 32 per cent of the time that trialists spent watching TV on their mobiles was accounted for when they were in their own homes.

As you'd expect, the big broadcasters in the UK have already underlined their intentions to get a large slice of this lucrative

pie. Sky has taken an early lead by offering a free service (at least initially), while the BBC and ITV are said to be planning a trial service to run for the remainder of this year. The pair have a rumoured £10-per-month subscription service that will offer a selection of mainstream channels.

But this could be exactly the sort of pre-launch propaganda that sets over-excited early adopters up for a fall. There's limited evidence to show the technology is ready to offer a quality of service people are coming to expect of the next generation of mobile phones.

Plus, there's no magic solve-all chip that means these devices don't have to abide by the laws of every other mobile on the market - battery life, drop-outs and low-screen resolutions will still be an issue. Whereas in the living room you have an unlimited
power supply, a direct cable or satellite connection and a huge television, TV-enabled mobile phones have to use the same tiny batteries and power-hungry backlit LCDs we've been using for sending texts.

Even if operators overcome these technical shortcomings, they still have to worry about licensing the content that will attract and maintain the customer base. Getting rights holders on board is something that's troubled the BBC with its Integrated Media
Player (iMP) project. The broadcaster's technical trials were able to prove that peer-to-peer worked as a delivery mechanism for on-demand television, but the whole process was still held up by copyright holders' demands. This will prove equally difficult for mobile TV, as programme makers have been used to selling content based upon it being delivered on one platform only. And there's no point having a product that provides good enough picture quality if the broadcasts aren't worth watching in the first place.

So now is the time to keep an eye out for the false promises of mobile TV marketeers. Remember BT's 'Surf the net, surf the BT Cellnet' slogan? That advertising trick led many to believe they could access the full internet on their WAP-enabled mobile phone,
and yet the mobile web of 2000 was an over-hyped collection of static, text-based clumsy screens.

As with the first generation of the mobile internet, you'd probably be best served peaking over a friend or colleague's shoulder at their mobile TV handset before signing up. Fully fledged, live TV on your mobile would be a welcome distraction for many commuters, but don't be distracted from the fact that it's unlikely to live up to the over-inflated promises.
