Voice of Việt Nam (VoV) ponders DRM as a national solution

"The Digital Radio Mondiale (DRM) Consortium and the Vietnamese public broadcaster, Voice of Vietnam (VoV) will hold their first comprehensive digital radio workshop in Hanoi, Vietnam on March the 10th. Vietnam is a large coastal country, with a varied geography and many towns and villages; VoV is exploring ways of meeting the challenge of covering in a spectrum and energy-efficient way the entire country with quality broadcasting services that can be received by its entire population.

Mr Nguyen Dang Tien, President of VOV, says: “VoV is the largest public station in Vietnam covering the entire country with radio programmes in analogue mode.  In our radio digitisation process we are looking at the most effective ways to cover both large cities but also regional towns and villages over large and geographically diverse territories. We wish to understand the full potential of DRM and the way it could ensure the full and cost-effective coverage of our large country.”

The comprehensive DRM workshop should ideally be followed by a trial which could be run together with the excellent Vietnamese specialists. This will give them the opportunity to experience the quality and benefits of DRM digital radio broadcasting, while the Consortium will learn more about an important Asian country.”

The workshop will be supported by key international DRM Consortium members, Fraunhofer IIS, Ampegon and GatesAir."

Ruxandra Obreja, DRM Consortium Chairman, is delighted to have the Consortium support VoV in their endeavour: “We believe that the global, open DRM standard (in both AM and VHF modes) will be able to offer enhanced broadcast services and data, to both urban and remote areas.
