DVB-T2 is the latest version of digital terrestrial tv transmission.
Terrestrial transmission means telecast of tv channels without satellite, mostly using fixed antenna stations.
Doordarshan telecast is an example of terrestrial transmission. So far doordarshan was using anologue terrestrial transmission.
Recently doordarshan started digital terrestrial transmission in test mode. DD has started using DVB-T2, latest technology. (DVB-T is the older technology, which is still in use in many south American and European countries.)
The advantage of digital over the analogue technology for terrestrial are :
1. More number of channels can be transmitted. (upto 100-150 channels possible)
2. Small size antenna only required at receiver side. (portable antenna with micro USB connector available now which can be directly plugged into mobile phones)
According to various news website reports, Doordarshan is preparing for a 100+ channel bouquet service in DVB-T2. It will be a free service like DD Freedish.
And DVB-S2 is the current days technology of Satellite based tv transmission.
