Phone giant Nokia (showthread.php?t=10735#) completes the most extensive trial yet of cellphone (showthread.php?t=10735#) TV technology - it concludes that quality on the move is sharp and steady
WE TALK on them, send text messages (showthread.php?t=10735#) with them, surf the web, play games and use them to take pictures. And soon, if cellphone makers have their way, we will be watching TV on our phones (showthread.php?t=10735#) too.
Cellphone giant Nokia last month passed a milestone in the drive to introduce mobile (showthread.php?t=10735#) TV when it completed the most extensive trial to date of the technology. This week, the company released a report on its trial of the mobile TV system, known as Digital Video (showthread.php?t=10735#) Broadcast-Handset (DVB-H), with Finnish state broadcaster YLE.
The six-month trial in the Finnish capital Helsinki culminated in live coverage of the World Athletics Championships there last month. It successfully demonstrated that the technology can deliver sharp, steady pictures with clear stereo sound to people on the move.
The 500 people in the trial paid a flat rate of ?5 per month on top of their standard cellphone subscription, plus extra for sports highlights such as Formula 1 car racing. This allowed them to use modified Nokia 7710 multimedia (showthread.php?t=10735#) phones to watch mobile TV for an average of 30 minutes a day.
Using a similar phone lent by organisers of the trial, I was able to watch clear pictures of the athletics on the 7 centimetre screen, as well as news from CNN and the BBC, while travelling around the city on a bus.
Smaller technical tests of the system have previously taken place in the US, Austratila, Malaysia, France and South Africa. And this month, UK cellphone operator O2 (showthread.php?t=10735#) will hand out phones to 300 families in Oxford to gauge how adults - and more particularly their children - use the devices to watch news, pop video chart shows and cartoons.....
Not going to type out the rest :p
Bascially DVB-H sends packets of information like on the net,
Pictures are very clear, even when constantly on the move
Since mobile displays are small, not much detail is needed so lower data rates only, thus more channel viewing options, up to 30, unlike 5/6 on terrestrial.
Problems...Small text such as subtitles will be nea rimpossible to view...may introduce "zooming" option
Potentially more serious is problem of battery life (showthread.php?t=10735#)..
"Batteries small and light enough to be suitable for a mobile phone (showthread.php?t=10735#) will only be able to provide around 3 hours of TV viewing, and this will be reduced further if the phone is also used to make calls. Nokia ecpects to increase this to 4 or 5 hours eventually. But users are not going to be impressed if after watching a football game they cannot make an urget call because their battery is flat"
