World’s Most Advanced Digital Television Systems Demonstrate Their Technical Superiority With 3DTV Transmissions
AMSTERDAM — 10 – 14 September 2010, Amsterdam RAI, IBC Stand No. 1.D81 — At this year’s IBC, the DVB Project is demonstrating the powerful capabilities and superiority of its second-generation broadcast transmission systems. Visitors to the DVB stand can see, for the first time ever, live High Definition 3DTV broadcasts of all three standards – DVB-T2, DVB-S2 and DVB-C2.
DVB-T2 is the world’s most advanced digital terrestrial transmission system offering higher efficiency, robustness and flexibility. It builds on the basis of DVB-T and adds new modulation, coding and error correction techniques that are also used in DVB-S2 and DVB-C2. This results in a 50% efficiency increase over any other DTT system in the world. For the DVB-T2 demonstration, live transmissions from the Amsterdam TV tower come courtesy of Arqiva. The signals are received by ADB, and Humax DVB-T2 set-top boxes.
DVB-S2 offers a wider choice of modulation modes, coding techniques and a very powerful Forward Error Correction scheme. This gives DVB-S2 an increased performance of at least 30%, approaching the theoretical limit. The live DVB-S2 transmission is via a WORK Microwave DVB-S2 modulator and is received with a Kathrein DVB-S2 set-top box.
DVB-C2 uses similar state-of-the-art coding and modulation techniques employed by DVB-T2, which offer more than 30% higher spectrum efficiency. After analogue switch-off, the gains in downstream capacity will be greater than 60% for optimised HFC networks. The chosen COFDM modulation scheme also offers increased performance. The first end-user DVB-C2 products are expected by 2011. The DVB-C2 demo is enabled by utilising DekTec DVB-C2 modulator and demodulator boards. Content used in the demonstrations is courtesy of The Walt Disney Company and Deutsche Fussball Liga. 3D LCD TVs for the demonstrations are supply by LG. Transport stream editing is by Tara Systems.
Peter Siebert, DVB’s Executive Director commenting on DVB’s technology demonstrations said, “IBC is a fantastic opportunity for DVB to showcase its technologies and this year we have put together three excellent demos which highlight the superior performance that DVB’s second-generation broadcast transmission systems bring to the marketplace”.
DVB representatives and technology experts are on hand to answer queries and provide information on the implementation of the world’s most successful set of technical standards for DTV. DVB’s open, interoperable standards form the basis of services on every continent with an excess of half a billion receivers shipped.
