Berlin demonstrates the viability of Multi-PLP in DVB-T2

Berlin carries out tests in DVB-T2 to demonstrate the viability of Multi-PLP. This technology would allow broadcasters to combine a series of services including SD and HD signal broadcast, radio and mobile services.

The DVB Project Office has recently carried out a series of tests in Berlin based on the DVB-T2 standard in order to test the viability of Multi-PLP (Multiple Physical Lyer Pipes). This technology would allow broadcasters to combine a series of services including SD and HD signal broadcast, radio and mobile services.

During this experience in which Media Broadcast has participated, it was broadcast from the Alexanderplatz communications tower in Berlin in a totally real environment of contribution and distribution with signals supplied by the participating channels as well as other test ones. The signal transmission was carried out through channel 51 with a transmission power of 2.3kW.

This channel broadcast two physical layers in the same multiplex. Layer 1 allowed reception of a high-definition television channel encoded in H.264 with a data rate of around 10 Mbps via an outdoor antenna. Layer or level 2 was optimized for mobile reception at home with three SD channels. Programs encoded in H.264 were transmitted equally on the statistical multiplex with an average data rate of 3 Mbps.

In the coming days, a stereoscopic transmission experience is planned to take place at the T2 multiplex in collaboration with the Fraunhofer Heinrich Hertz Institute in Berlin.
