Roadmap for the Transition from Analogue to Digital Terrestrial Television in Nepal

The Nepal National Roadmap Team (NRT) has developed a digital switch-over (DSO) policy for a smooth switch-over to digital in phases, conversion starting with transmitters with the highest coverage of population and each phase having coverage equivalent to that of the existing analogue transmission. Simulcast will continue within the coverage zone of a particular transmitter till at least 90 per cent of the viewers who were receiving analogue are equipped with a set top box (STB) or integrated digital television (IDTV) so that they continue to receive programmes without interruption after which the analogue switch-off (ASO) of that station takes place. The analogue equivalent digital coverage is expected to be completed in five years and complete ASO has been targeted for December 2017. The first digital experimental transmission is expected to start from Kathmandu, having the highest population, by July 2012. The NRT has recommended DVB T2 as the digital terrestrial television broadcasting (DTTB) standard in Nepal and DVB-H as the standard for mobile television (MTV). Though standard selection has been made for MTV, its implementation will have a lower priority and would be taken up on market demand and after implementation of the DTTB plan.




The process of transition from analogue to digital terrestrial television broadcasting offers advantages in terms of spectrum efficiency, higher video and audio quality and new business opportunities. It also offers the opportunity to allocate part of the broadcasting band to International Mobile Telecommunication (IMT) services and other applications.
