DVB-T2 Implementation Guidelines DVB-T2 Implementation

Nick Wells, BBC, Chairman of DVB-TM-T2 Group & Oliver Haffenden, BBC, Editor of T2 Implementation Guidelines DVB-TM-T2 Group & Oliver Haffenden, BBC, Chairman of Nick Wells, for digital DVB-T2 is a new standard terrestrial television broadcasting, offering the benefits of many new techniques not previously used in the DVB family of standards. Some of the techniques are well known in the literature but were modified and optimised for DVB-T2; others are completely novel and were developed specially for DVB-T2.The new technologies include: ‘P1 preamble’ whichA is useda) to indicate the start of theT2 framing structure, b) Physical Layer Pipes (PLPs) which can be used to carry individual data streams with individually assigned individual levels of ruggedness, c) Rotated Constellations, which can provide significantly improved levels of robustness in difficult broadcast channels, d) Peak-to-Average power reduction mechanisms involving a combination of reserved OFDM carriers and constellation distortions, and e) Modifications of data cells and scattered pilot patterns in order to enable optimised reception when using transmitter diversity. The DVB-T2 Implementation Guidelines (IGs) document, recently published as DVBA133, BlueBook gives information about the benefits and use of these new techniques as well as all the other techniques used T2. in t how

In this regard the economies of scale engendered by DVB-T being the most widely adopted and deployed system are evident, with set-top boxes retailing at less than EUR20. (Projections from DTC – see page 12 – predict that sales of DVB-T receivers will far outpace those of andATSC ISDB-T receivers in the next five years. Greater economies of scale will lead to even lower prices.) October 2008 saw the initiation of a new phase of cooperation between Europe and Colombia covering a wide range of activities including: technical and business model assistance; spectrum management; scientific and technological cooperation to launch common projects under the European Union Seventh Framework Programme; etc.The governments of Spain, France, Finland and associated experts are engaged in setting up cooperation agreements with the Colombian government. Having adopted it is DVB-T, not surprising that the Colombian authorities are also promoting the use of DVB-H for mobileTV services.An announcement in January this year from the CNTV indicated that licences to broadcast DVB-H services would be made available at zero cost later in Accordingthe year. to RapidTV News, Mexican-ownedAmérica Móvil has already expressed an interest in applying for a licence. numberA of other countries in the region are in engaged in selecting system, amongst them Peru, a DTT Ecuador, Panama, Venezuela, Bolivia, Paraguay and the Dominican Republic. All of these countries, and others, will have noted the decisions of Uruguay and Colombia. DVB supporters in Latin America, with support from the DVB Project, the European Commission and European governments, are fully committed to providing demonstrations, holding seminars and responding to consultation documents. The potential is there for DVB-T to become the system of choice for the region as a whole.

it’s almost three years since Brazil almost three years since Brazil it’s chose to adopt a version of ISDB-T as its DTT system. So withfar, the SBTVD (Sistema Brasileiro de Digital),Televisão Brazil is the only country worldwide to have adopted the Japanese system. In contrast, DVB-T services have been launched in almost forty countries and the system has been adopted by 120 countries for details.) www.dvb.org (Visit globally. Progress in Colombia towards launching DVB-T services has been swift. Preparations are under way to launch a pilot service in May 2009, less than a year after the adoption The first decision was announced. transmissions will cover about 11 million households in central regions, served by a transmitter located in The public the hills outside Bogotá. broadcasters will be the first to have their services on the digital platform, with private broadcasters set to follow. full launch of services is scheduled A to take place in 2010. The CNTV’s strategic plan, which was sets published in January this year, aside 90,000 million pesos (approx. EUR 28 million) for the implementation of digital terrestrial television.Already more than 3,500 million pesos has been invested in preparation for the further A launch of the pilot service. 300,000 million pesos is earmarked for strengthening public television. Other aspects of the strategic plan include commitments to promote universal access to services, improvements in service quality, and a strengthening of The the national production industry. strategic plan also calls for the addition of a third private channel.There are six nationalTV channels in Colombia, two of which are private broadcasters. One of the key factors that led Colombia towards a decision in favour of DVB-T was the potential socio-economic impact of the system chosen. With a population of 45 million and a per capita GDP of USD $9,000, a successful transition from analogue to digital in Colombia will be dependent on the abundant availability

On AugustOn 28th last year it was announced by the Colombian National Committee for (CNTV)Television that DVB-T had been adopted as the national standard for digital terrestrial television (DTT).The decision followed a two year period of studies comparing the various available systems under a range of criteria and represented the unanimous agreement of the five-person committee. It was also video AVC announced that MPEG-4 compression would be used for the launch of services. The adoption of DVB-T by Colombia was warmly welcomed by the DVB Project and the wider community of DVB supporters, particularly as it came one year after a similar decision by Uruguay, which was the first country America to adopt DVB-T. in Latin There now seems to be a momentum in the region towards DVB standards: ps ste Seseña & Eoghan O’Sullivan Julian DVB’s Digital Switch to a Look at Colombia’s Take xt ne
