Vietnam started Digital Terrestrial TV with a first trial in 2000. After a simulcast period from 2011 to 2015, the analogue switch-off has been scheduled from 2015 to 2020. While the first networks used the DVB-T system and MPEG-2 encoding, the networks are now progressively converted to DVB-T2 and MPEG-4.
Vietnam Television Corporation (VTC), one of the three nationwide broadcasters in Vietnam, initiated the conversion in 2016, with the upgrade of six high power sites in six major cities. To perform this upgrade on six existing 10 kW IOT based transmitters, VTC selected TeamCast’s DVB-T/T2 TWISTER exciters, because of their high adaptability to existing transmitter architectures and their high level of performance.
