AEC challenges for analogue switch off

AEC challenges for analogue switch off

Tode MitreskiOhrid, may 2011

The digital switchover process is underway

Around the world, countries have launched their digital terrestrial television (DTT) services

And begun planning to switch off their analogue networks

A few pioneer countries in Europe have already completed the process


analogue switch-off is not easyEnding the transmission of analogue servicescan have dire consequences should viewers not be

adequately preparedThe process of analogue switch-off will differ in

countries


The experiences of countries that have completed analogue switch-off

Understanding which approaches work best, as well as pitfalls that should be avoided, can help ensure a successful process

Goals of analogue switch-off

Switching the terrestrial platform from analogue to digital technology is no easy feat

The full broadcast network must be converted

The process is fully justified because digital switchover brings many benefits to the government, broadcast community, and general public

Spectrum efficiency

By converting the terrestrial television platform from analogue to digital technology, countries can benefit from the increased spectrum efficiency offered by digital technology

To ensure the maximum benefits of digital switchover, countries in a given region should agree to convert to digital broadcasting if possible using a coordinated approach

The agreement sets 17 June 2015 as the date after which countries will no longer be required to protect the analogue services of neighbouring countries against

interference and be able to freely use frequencies assigned for digital services

Securing the future of the terrestrial platform

Viewers have many different options for accessing television

services

The emergence of new television platforms has provided

viewers

with new television opportunities, such as more choice and

premium content in comparison with the terrestrial platform

The launch of a new multichannel service, often freely available,

has helped the terrestrial platform to successfully compete with

other television platforms

Where to begin the process?

Determining where to begin the analogue switch-

off process varies between countries

Some countries, have begun the process in large

urban areas with high population densities but few

transmitters

Other countries, especially those with a high

reliance on the terrestrial television platform, have

opted to begin the process in areas with low

population densities

In some countries, analogue switch-off has been

tested in pilot areas

National approach to analogue switch-off

In a national approach to analogue switch-off, analogue services

are ended simultaneously across the whole country

All viewers benefit from the advantages of digital switchover, as

viewers are treated equally and given the same access to

services but equally all suffer from the need to equip for digital

services in VHF and UHV bands for whole territory of

Macedonia

Number of issued licenses for analog TV: 549

Number of issued licenses for digital TV: 30

Cooperation among neighbor countries in the process of digitalization –WHY?

Different dates of launching of DVB-T in the countries of our region;

Because of the large number of issued licenses in Macedonia (national and local TV stations) we were not able to assign fully digital multiplexes according GE-06;

Occurrence of problems in border zones when all the neighbors

will begin with simulcast ;

AEC signed memorandums of understanding with regulatory bodies in neighboring countries: Bulgaria, Kosovo, Albania, Serbia and Greece; • basis for further cooperation and resolving problems that will

arise in the process of digitalization in the region
