DVB-T, analogue systems B and G utilize the same 250 kHz guard-band. After analogue television transmissions have ceased, only the preferred main carrier wave centre frequency should be listed, because QAM modulates all AV channels and other data into a single H.222 data stream.
In March 2006, DVB decided to study options for an upgraded DVB-T standard. In June 2006, a formal study group named TM-T2 (Technical Module on Next Generation DVB-T) was established by the DVB Group to develop an advanced modulation scheme that could be adopted by a second generation digital terrestrial television standard, to be named DVB-T2.
The first DVB-T transmission was started on 26 January 2003 in the four major metropolitan cities by Doordarshan. [8] Currently the terrestrial transmission is available in both digital and analog formats. Four high-power DVB-T transmitters were set up in the top 4 cities, which were later upgraded to DVB-T2 + MPEG-4 and DVB-H standards.
