The DVB technology has been around for many years. In the UK, DVB-T (Terrestrial) is in widespread use for its Freeview service, enabling digital TV services to most of the UK population.
DVB is not like current TV services found on Mobile in the UK currently, where it uses the networks Data service to stream the content. It actually is broadcast through the air like without the need for a radio signal to carry the data communication (GSM/CDMA).
However, in Korea, they have had DVB-S (satellite) in widespread use on the average handset for a few years now. Most devices released by Samsung/LG for the western market is frequently shipped as a reduced version of the Korean model. For example, the Ultra series by Samsung are known for their slimness, however, the Korean models also feature DVB. The LG Prada, recently released in Europe, has also a Korean release, again with DVB support.
DVB support is not limited to open air location in Korea either, it is fully functional on the Subways in Busan and Seoul. Relays re-broadcast the satellite signal deep underground to the mobile users on their daily commute.
So why do we, here in the UK, suffer this lack of functionality that many people desire so much. What the industry say is that they are still deciding on the correct protocol to use, DVB-H (Handset) is currently the proferred choice.
My opinion on this fact is different. I feel that the networks are able to draw a revenue stream from using data services to stream the TV. Also, in the UK, all television users must pay a license fee, on mobile devices, this will be harder to control, and a new payment or licensing model will have to be drawn up to support such a service.
Having seen how small the DVB chip is that supplies this functionality, there is no excuse that the device will compromise on ergonomics. As seen in Korea, they are able to fit this into a case less that 8mm thick!
I hope towards the end of this year, standards are finalized, and devices are shipping. Delivering entertainment to those bored commutes!
