DVB-T, short for Digital Video Broadcasting – Terrestrial, is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 [1] and first broadcast in Singapore in February 1998.
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.
VK3RTV is an experimental Amateur Television Repeater licensed by the ACMA to Amateur Radio Victoria. In late September 2009 the former single analogue channel was converted to a 2 channel DVB-T digital system. The output of the transmitter is on 445.5 MHz which can be received on some set top boxes and digital television sets.

[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.
DVB-T channel allocation notes: The allocation for terrestrial television must be seen in terms of uniform system G 8 MHz blocks (for bands IV and V in NZ) and system B 7 MHz blocks (for bands I to V in Australia) after the cessation of analogue television. DVB-T, analogue systems B and G utilize the same 250 kHz guard-band.
Some countries such as Germany, The Netherlands and Belgium may only broadcasts their channels in standard definition via the terrestrial airwaves. This is largely because the uptake of cable television may be higher than that of terrestrial television, thus giving broadcasters very little incentive to provide their high-definition services via the terrestrial airwaves.
