Already, following this 2010 was another busy year for DVB. recommendation the governments in Altogether 33 DVB documents were South Africa as well as in Mozambique processed and published by ETSI which have adopted DVB-T2 as their digital is the highest number ever. Of these terrestrial system. In addition to Africa, 33 documents about 30% are new Australia as well as countries in Asia specifications including, for example, the including India, Sri Lanka and Singapore 2nd generation cable specification and have registered a big interest in this new Peter Siebert corresponding guidelines document. The technology. Executive Director remaining 70% are revised versions of After having been so successful in already existing DVB documents where 2010 what is in store for the future? revolutionize the way video, as well data, the reasons for the updates are typically 2011 will see a new standard for mobile is delivered via cable systems. We will market requests for new features. In broadcast which will build on the also see additional deployments and addition to face to face meetings, a performance and flexibility of DVB-T2. growth for T2. significant amount of this work has been The DVB group working on the 2nd So, right now, it looks as though done in telephone conferences, thus generation return channel via satellite 2011 will be an equally as busy and saving travel costs and reducing carbon specification will deliver a complete set successful year for DVB as 2010. But, emissions. The DVB Project Office is of standards from the physical up to the will we be able to continue this trend supporting this initiative by providing systems layer. As I write, the Technical forever? The answer is of course open. the necessary infrastructure for telephone Module has adopted the specification But even when the standardization conferences and web meetings. for frame compatible 3DTV, including activities of DVB may one day slow 2010 has also been a successful year the necessary extensions for 3D subtitles. down we should not forget that DVB is for the adoption of our specifications, Work on the commercial requirements about more than standardization. We are especially DVB-T2. By all accounts for a second phase of 3DTV has just also a forum bringing together all major the market introduction of Freeview started and we anticipate that there will players in the broadcast industry such HD, which is based on T2, has been be a lot of activity around the further as broadcasters, manufacturers, network a success. In addition to the UK, development of 3DTV. Furthermore, operators and regulators. Furthermore, Finland and Sweden have started to 2011 will bring us a new version of the we facilitate the introduction of new roll out T2 services. Following this DVB Measurement Guidelines covering services and technology.
