THE JUBILEE OF MERCY: EXTRAORDINARY ALSO IN THE VISION, LIVE IN 4K-UHD

Great success for the the first worldwide live in 4K-UltraHD – and in HD simultaneously – realized for the opening ceremony of the Holy Door at St. Peter’s Basilica in Rome. A unprecedented event produced by the Vatican Television Center (CTV) in cooperation with the Vatican Radio and with technological support of DBW Communication, Sony, Eutelsat and Globecast.
The excellent team’s work has allowed to make a very important test at the end of the celebration: the first live via satellite in High Dynamic Range (HDR) using the Hybrid Log Gamma profile, the new standard developed by BBC and NHK which makes it possible to broadcast a single signal/stream compatible with both non-HDR and HDR 4K televisions.

The HDR (High Dynamic Range) system is the new development of the 4K standard and it is able to guarantee an extraordinary color depth and a much wider luminance range as well as a never before seen strong contrast between the bright parts and the dark parts of the image.
