Singapore – In advance of Broadcast Asia, ENENSYS, designers and manufacturers of digital TV transmission technologies, announced on June 3 that it has supplied its OneBeam solution to Thai TV5 for its DVB-T2 digital terrestrial TV network. The network optimisation system comprises: T2 Gateways, IPGuard Seamless Switches and T2Edge local adapters for Thai TV5 in Bangkok for its DVB-T2 digital terrestrial TV network.

The new DVB-T2 network has launched with transmitters in the cities of Bangkok, Nakhon Ratchasima, Chiang Mai and Songkhla with TV5 providing two multiplexes delivering a total of 14 TV channels. Additional transmitters will be commissioned over the next 18 months, providing terrestrial TV reception to 95 per cent of Thai households.

ENENSYS T2 Gateways and seamless switches are installed at the Bangkok head-end, with distribution to transmitters over satellite and IP links. The “must carry” requirement in Thailand means that the terrestrial TV channels must also be broadcast on DTH free-to-view satellite within the Kingdom. This ENENSYS OneBeam solution enables the DTH satellite service to be used to feed the DVB-T2 transmitters, delivering significant savings in satellite transponder capacity and operational costs.

ENENSYS T2Edge units at each transmitter site build the T2 multiplexes for transmission, enabling Single Frequency Network operation of transmitters. The T2Edge also implements the Emergency Warning System, replacing all normal TV programmes with an emergency TV service under the control of the disaster coordination centre in Bangkok.
