Digital TV broadcast

 

Factors necessitating a transition to digital broadcasting

 

 

The rapid development of information technologies in the world and the increased information needs of people necessitate upgrading the television broadcasting network in accordance with the latest standards.

 

At the start of the nineteen eighties results of scientific research carried out in all developed countries coupled with certain problems experienced with analogue television broadcasting, led to the development of and transition to digital television broadcasting. This process accelerated towards the end of the twentieth century.

 

As a result of research carried out by the International Telecommunication Union (ITU) in this field, appropriate decisions for the transition to digital television broadcasting were adopted at the Regional Radio Communications Conference held in May 2006 in Geneva, Switzerland. It was agreed to accomplish this transition by 2015.

 

Currently the transition to digital television broadcasting has been accomplished in some European countries and it is anticipated to be completed in other countries during 2012-2013.

 

The main factor necessitating the transition to digital television broadcasting in this country is a demand for high quality television reception, efficient use of limited frequency resources and the need for mobile television.

 

Current situation existing in broadcasting

Currently approximately 30 radio and television programs of state, public, private and foreign companies are broadcasted in the Republic of Azerbaijan. At the moment coverage by state owned programs reaches 100% of the population. Private Television and radio broadcasting currently can be received in approximately 75-80% of the country.

 

In parallel with the analog broadcasting, digital TV standard DVB-T covered more than 95% of the population.

 

Aims of the project:

The project aims to provide the transition from an analogue to a digital informatization regime on a stage-by-stage basis for the whole territory of the country. Transition to digital broadcasting will enable the delivery of different content and an increased level of information to the user at greater speed and in high quality.

 

Description of the project:

Test broadcasting for transition to current standards applying internationally has been underway in Azerbaijan since 2004.

 

According to the order # 274 of the Cabinet of Ministers of Azerbaijan Republic dated September 13, 2006, application of DVB-T European standard was considered expedient for broadcast of digital TV in the territory of the republic and

 

The program “Application and development of the DVB-T digital television system in the territory of the Republic of Azerbaijan” was approved by the decision #26 of the Cabinet of Ministers dated February 10, 2011.

 

The program plans the completion of transition to digital television broadcasting for the whole country by 2013. It is planned to broadcast digital television in parallel with analogue television in this stage.

 

Broadcast of analogue TV programs in the country will be stopped stage by stage starting from 2013.

 

Implementation mechanism and efficiency of the project

Currently, more than 95% of the population is covered with open package (10 TV programs- AZTV, ITV, Idman, Medeniyyet, ANS, Lider, Space, ATV, Khazar, TRT1) digital DVB-T MPEG-4 standard TV broadcast and digital broadcast is now carried out in parallel with analogue one through the installed 48 digital TV transmitters including Baku, Ganja, Lerik, Aghsu, Aghstafa, Imishli, Mingachevir, Shirvan and other TV stations.

 

Thus, all cities and regions and surrounding residential areas of the country are covered with open package digital TV broadcast. In addition, open package digital TV has been broadcasted in Nakhchivan AR since the beginning of 2012 and digital TV covers 51 % of the population of Autonomous Republic. Additional measures are being taken to cover the rest part of the country’s population (here includes population living in remote mountain villages and settlements that do not receive digital signal due to the nature of the relief ) with digital TV broadcasting.

 

For the reception of digital TV programs in the republic, it is considered necessary for the population to use digital TV or receiver/ converter devices (set-top boxes). Currently, the country has already started production of digital converters and at the same time, sale of converters and TV sets made in foreign countries, is organized in the country.

 

Expected results:

  • The number and quality of TV programs broadcasted in the Republic will increase
  • Favorable conditions will be created for a more efficient use of frequency resources;
  • Broadcasting of 10 or more programs in one television channel will be possible;
  • High quality television broadcasting will become possible, using
  • transmitters with less power consumption compared to the analogue system;
  • Interfering signals from neighboring countries will be minimized;
  • There will be no need for satellite antennas (VSAT)
  • It will be possible to transmit information on additional services (weather forecasts, schedule of public transport, advertisements, etc.) along with television programs and simultaneous sound accompaniment in different languages will be possible.

 

Note that Teleradio PA has been implementing commercial broadcasting of multiprogram digital TV packages in Ganja since 2012. At first, the broadcasting was organized in DVB-T standard, and it was transfered to DVB-T2 standard in 2014. As a result of the implementation of commercial broadcasting, the population of Ganja and surrounding territories (Samukh, Yevlakh, Goygol, Mingachevir, Shamkir, Goranboy etc. ) got a chance to watch 90 various TV programs of Azerbaijan, Russia, Turkey and other countries considered for children and adults. To increase the number of users, the price of commercial broadcasting was brought into accord with the social status of the population.

 

Moreover, Teleradio PA began to implement commercial broadcasting of DVB-T2 standard multiprogram digital TV packages in Guba region for the first time in 2014. As a result of it, the population of Guba, Gusar, Khachmaz, Devechi regions and other surrounding regions got a chance to watch 60 various TV programs of Azerbaijan and foreign countries. Teleradio PA considers continuously organizing the commercial broadcasting in the South of the country and in Shaki-Zagatala region.  DVB-T2 standard commercial broadcasting of “ATV+” is implemented in the territory of Baku city and Absheron peninsula from Baku TV power complex which belongs to Teleradio PA.
