TeamCast, a specialist in digital modulation technologies for DTT, Wireless Transmission and Satellite Applications, is contributing to the migration of DTV from DVB-T to DVB-T2 in Vietnam.
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.
After the high power sites are converted, it is expected that the process will continue in 2017 with medium and low power sites.
“Beyond their easy integration in our transmitters and their high RF performance, we selected TeamCast’s TWISTER exciters because their are easily controlled remotely and bring a top-class adaptive pre-correction which ensures the highest signal quality and highest energy efficiency with our existing IOT amplifiers” says Do Hoang Kien, Manager, VTC’s Broadcasting and Transmission Centre.
“We are proud to be selected by VTC for doing this conversion to DVB-T2, as it confirms what we observed already in some other countries doing the same conversion. TWISTER really meets the operational requirements of operators when it is time to upgrade existing transmitters to DVB-T2, preserving the original investment they made in their early DVB-T networks. We do thank our local partner AVTEC who helped us a lot to do this project” says Eric Pinson, Business Unit and Sales Manager at TeamCast.
