do DVB-IP devices require IP addresses

Anybody knows what is the IP thing in DVB-IP, does it use IP addressing and hence can be delivered to only a devcie which has IP addressing?

The digital radio standard DAB has been revised, allowing it to be used for the transmission of mobile TV via Internet protocol (IP).

The European Telecommunications Standards Institute (ETSI) approved the revision on Tuesday, paving the way for services such as BT Movio, soon to see its first commercial launch by operator Virgin Mobile.

DAB-IP has potential competitors, such as DVB-H (which can supply a greater range of channels), but is currently the only standard for true IP-based mobile broadcast that can be deployed commercially in the UK, as the spectrum needed for DVB-H isn't available.

The managing director of BT Movio, Emma Lloyd, said on Tuesday that DAB-IP's approval supported BT's view that "we will see multiple standards for mobile TV and radio appearing in different markets across the globe", and that "those adopting a multi-standard approach will therefore emerge as the winners in this potentially lucrative market".

"Consumers want simple access to high-quality TV and radio wherever they are. By using a platform based on IP, we can join different technologies and standards together to give the consumer a seamless experience to enjoy their favourite TV and radio programmes on their mobile phone," she said.

BT Movio claims that users involved in the service's trial stages found DAB-IP's choice of digital radio channels, as well as TV, to be an advantage.

However, the company also claimed it will be able to provide a "seamless" integration of upcoming standards such as DVB-H.

O2 trialled a mobile TV service based on DVB-H in Oxford last year, and BSkyB is testing Qualcomm's MediaFLO digital mobile TV technology.

 
DVB-IP and DAB-IP are basically methods of sending IP (Internet protocol) data over DAB or DVB transports. In other words, it's a method of using DVB or DAB as a from of broadband connection. Essentially, this must mean the recipient supports TCP/IP and has an IP address - this isn't really a significant issue, as the prevalence of always-on mobile data systems (e.g. GPRS) means that any mobile device can easily get an IP at any time.

Receivers for both DVB and DAB are now commodity products - and they are both capable of carrying substantial data - so they are a sensible choice for provides who wish to broadcast a large quantity of digital data to mobile recipients. Because these services are IP based, data can be addressed to individual recipients allowing a more interactive service.
 
This technology is already out in market to public in some of region I guess.. with flawless consistent connectivity.. =]
 
thanks for the replies

could it be possibel for DVB-IP to use UDB/IP?

so the IP based solution would allow TV to be multicasted and also enable interactive TV
 
That's essentially it - the technology is best suited to massive multicast (e.g. multiple broadcast streams, tickers, etc.). Invididuals could also receive smaller bandwidth streams, although it's unlikely that there would be sufficient bandwidth for everyone to receive a personal stream simultaneously, over a conventional public network.

DVB-IP can carry any form of IP traffic, including UDP as well as TCP.

There is the possibiltiy of private connections (e.g. from the local cable company, or point-to-point microwave links) which could be used to connect multiple corporate LANs.
