Tech Papers 2019: This paper presents a method for including regional content in a national DVB-T2 SFN using multiple PLPs and DVB-SIS, demonstrating in lab tests that national and regional programs can be broadcast efficiently and flexibly, with application to the Italian case.
Abstract
To include regional contents in a national Single Frequency Network (SFN), Rai has studied and tested in the laboratory a system configuration that benefits from the multiple Physical Layer Pipes (PLP) of DVB-T2. According to the proposed solution, in each region the national programmes are transmitted in one PLP, while other k PLPs convey the regional contents of macro-regional SFN, formed by a region and the (k-1) surrounding ones. The DVB Single Illumination System standard (DVB-SIS) can be a valid technical solution to distribute such complex signals to SFN transmitters via satellite or terrestrial contribution links in a cost-effective way.
