DVB Scene published our article: “Optimizing satellite signal delivery based on DVB-SIS”

News | September 27, 2023

Here is a short summary of the article:

The article explores Single Frequency Networks (SFNs) and how the DVB-SIS standard was created to address challenges linked to them by developing a method to transmit single satellite signal simultaneously to homes (DTH) and terrestrial receivers (DTT) as well as to insert regional content. The standard, DVB-SIS, enables capacity savings of up to 95%.

Building on this standard, we developed a solution SFN Boost which extends DVB-SIS capabilities and gives broadcasters additional configuration options, such as the possibility to insert regional ads.

In comparison to DVB-SIS which is built on a distributed architecture where the signals are generated at TV transmitter side, SFN Boost gives the option to use a centralized architecture where the signals are generated at the head-end.
This brings several benefits, such as:

• No dependence on GPS synchronization, which meets a government requirement for critical infrastructure independence.
• More flexibility and redundancy in choosing any distribution path.
• Plug and play installation of adapters into existing DVB-T2 installations

In conclusion, DVB-SIS is a great standard that provides single beam transmission to DTH and DTT and enables regionalization. Building on the standard, SFN Boost can provide regional advertisements and other valuable features that make it a comprehensive solution for SFNs.
