I am just a new bee in this field and need to do a depth study on the both technology to propose some future studies.

same question again for subscription mobile content - will be available encrypted over RF?

Ha, I worked on this trial (Pilot actually, as this is a proven concept) as I work for Virgin Mobile.

The idea is simple, we used a modified HTC Feeler (aka: i-mate SP3i, Qtek 8020, T-Mob SDA) with integrated DAB receiver. The DAB receiver fed into Windows Media Player, and via 3x64kb streams we had 3 different TV channels playing live* (*Give or take 10-15secs). The system also feeds an EPG (Electronic Programme Guide) stream and has overhead for trickle downloads.

The streams are transmitted via the normal DAB transmission network, on bandwidth allocated for Data only under the licening agreement with the DTI in the UK.

Content is controlled using Windows DRM licensing, and licences could be downloaded directly with WAP or via push-message. This would allow for daily, weekly, monthly subscriptions, or one-off packages based on time/s viewed.

No reliance is placed upon the mobile network, or its infrastructure, apart from the re-selling and supply of licences to view content transmitted and any support required for the device used.

In my opinion, this system is better as no reliance is placed on the 3G network operator, it is simply a feed from a free to air DAB network with national coverage in the UK.

Alternatively, for more general digital television implementaton by country, the wikipedia has a comprehensive list.

At least in Norway the telecompanies don't distribute to much information about the nextgen mobile TV, and just states that it's comming.]]>Jan 19th 2006 4:24AMhttp://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/http://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/Denmark has about 80% coverage today, and they've just decided to extend this to 100% by the end of the year.

In addition, Norwegian broadcaster, NRK, has pretty much decided to use DMB instead of DVB-H, so the Norwegian digital terrestrial mediafuture seems to include DVB-T, DAB and DMB.]]>Jan 19th 2006 6:57AMhttp://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/http://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/
Norway is also using DAB for radio, and at the moment, it seems likely that they'll use DMB for handheld video.]]>Jan 19th 2006 7:15AMhttp://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/http://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/
The DVB-H handbook states that DVB-H should have its own multiplexes:

The preference for exclusively DVB-H multiplexes

Mobile handheld receivers have much smaller antennas than those used for fixed or portable television. In addition, mobile handheld receivers must be able to receive a signal from a variety of different locations and sometimes at high-speeds, for example in trains or in cars.
These factors need to be compensated by making existing networks more dense and selecting more robust modulation parameters. Therefore, the co-existence of DVB-T and DVB-H services in a single channel, although technically possible, is unlikely to be ideal.

As batteries improve and fuel cells become available I think DVB-T, ISDB-T and the possible Chinese standard, DMB-T will become dominant for fixed, portable and mobile reception. The question is when will the US, Canada and Mexico smell the coffee and switch to the world standard DVB-T or even DMB-T. The fact that Mexico and Canada have delayed any real action on implementing 8-VSB says to me that they are not all that excited about the disasterous US standard. I expect them to bolt from 8-VSB.

Brazil, again, has rejected 8-VSB and will choose between ISDB-T and DVB-T. Since they have been rational in the past I expect them to go with DVB-T.

Here is a video of DVB-T mobile reception in New York from one transmitter at 400 ft and one kW. We were using 3 inch and 12 inch omni antennas. No SFN, no additional on channel repeaters, just one small transmitter. One, back of seat, is a diversity receiver with two antennas. It is capable of handling six. The other two are single omni antennas. ]]>Jan 30th 2006 3:59PMhttp://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/http://www.engadget.com/2006/01/18/digital-television-part-ii-global-status/
