DVB-T2 standard successfully tested in Berlin
In the past few days completely new signals have been broadcast by "Alex" in Berlin. The reason was a so-called "plugfest" organised by MEDIA BROADCAST as part of the DVB project. A world premiere at the event was the first ever live broadcast of DVB-T2 signals in MPLP mode.
The abbreviation MPLP stands for Multiple Physical Layer Pipe. This mode enables extremely efficient and flexible use of available transmission capacities, thus making DVB-T2 even more attractive to content providers.
Partners
10 companies from Europe and Asia had set up their equipment in the MEDIA BROADCAST labs in order to test the wide variety of features of the new transmission standard under real conditions on their equipment, and to check its compatibility with other components of the signal chain. During the process it was notable that, despite some of these firms being in competition with each other, there was an open atmosphere in the labs and everyone gave each other the best possible support.
MEDIA BROADCAST had created the optimum infrastructure for this, not only in their premises but also in providing the test signals.
TV-Channels
A total of four TV programmes were on air (ARD, ZDF, RBB and Pro Sieben) in one MPLP multiplex, one of them in HD. This signal, with a bandwidth of approximately 10 Mbps, was optimized for stationary reception and the three SD signals, with a bandwidth of approximately 3 Mbps each, were optimized for portable indoor reception.
Conclusion
At the end of the three-day test period, all the companies were satisfied with the results achieved, and the findings obtained will flow directly into the further development of the equipment. Full-scale verification of the DVB-T2 standard has thus come a bit closer.
At the end of the plugfest a number of customers and partners of MEDIA BROADCAST were also able to find out at first hand about the new DVB-T2 features and the overall picture quality, enabling them to directly experience the current stage of development of the system.
