3.3.9 Evolution of DVB-T: DVB-T2 
the DVB-T2 is the second generation of the DVB-T standard. It was published at the end of 2008. This 
systems offers an improvement in efficiency in the use of the spectrum around 30-50% than the DVB-T. 
The characteristics of this system are the following: 
Ø
The priority is to be multicast on HDTV, SDTV, and to allow the interactive and other services in 
digital systems and mobile devices. 
Ø
DVB-T2 will work with the antenna systems existing, in transmission and reception. 
Ø
DVB-T2 will provide a higher transmission speed. 
Ø
The DVB-T2 specification should offer improved robustness against interference from other 
transmitters, compared to DVB-T, potentially improving frequency reuse. 
Ø
The DVB-T2 specification shall offer a choice of various robustness and protection levels to be 
applied equally on all data of a transport stream carried by a DVB-T2 signal in a particular channel. 
Ø
The use of this system in SFN will allow a greater distance between the existing repeaters than in 
the DVB-T system.

4. Digital TV on mobile devices 
One of the challenges for the mobile communications industries is to provide low-cost mass media, making 
them profitable for operators and accessible and affordable for users. One of the most important services is 
the Digital TV on mobile phones, which is expected to be the key in future mobile networks and it could open 
up a new market. Now cellular networks are restricted and can not support many services due to the high 
battery consumption that it requires the strong investment in network infrastructure needed to provide 
acceptable levels of coverage. 
In mobile terminals, TV programs can be delivered using cellular or dedicated broadcast networks. There are 
many systems and standards for video broadcast networks: T-DMB, ISDB-T, MediaFLO and DVB-H. [8]

DVB-H:
Digital Video Broadcasting Hand-held. Is adopted by ETSI as a European Standard of 
Terrestrial Digital TV (TDT) for mobile services.
