In this context, 4K UHD is now coming to our TV sets and the best example will be the next world cup in Russia in June that will be covered in 4K in all the stadiums and broadcasted to each country in its native format. 4K UHD requires 8 times more bandwidth than a regular HD signal.

Fortunately, for those now wanting to take any risk, some tips exist allowing well-known process, and a lot of broadcasters are using the 4 links 3Gbps technique.
