French broadcaster TDF is using Envivio’s 4K Ultra HD compression technology to test a broadcast of the NRJ Hits music channel in 4K.
From the Eiffel Tower in Paris, NRJ Hits, which is a leading French music channel, is distributed over the national digital terrestrial television (DTT) service. The ongoing DTT video transmission uses HEVC (H.265) compression encoding from Envivio over DVB T-2 delivered in 4K.
National regulator CSA authorized TDF to broadcast Ultra HD TV over the DTT network using the DVB-T2 standard from the Eiffel Tower. The 4K video that is being distributed is encoded at 50 frames per second using Envivio Muse Ultra HD encoding software on Envivio G5 appliances.
Earlier this year, TDF used Envivio’s 4K Ultra HD compression technology for live streaming of the French Open 2014 tennis championship to compatible 4K TV sets in France. Envivio said it was the first digital terrestrial television (DTT) broadcast video transmission delivered in 4K using HEVC (H.265) compression.
“Envivio successfully debuted live 4K HEVC video transmissions over a DTT network for us at the French Open tournament, and our confidence in Envivio continues to grow with this transmission of Ultra HD content from NRJ HITS,” said Alain Komly, deputy director at TDF.
“Wrapping up our successful broadcast of the World Cup, this transmission is yet another example of the technical power of our video processing software for over-the-air broadcast in 4K Ultra HD, and we are proud to work in partnership with TDF and NRJ using this emerging technology,” said Envivio’s Chief Technology Officer Jean-Pierre Henot.
