Nevion Virtuoso’s TICO media function enables encoding and decoding of UHD/4K video for transport over 10GE/IP or 3G-SDI links, with a visually lossless 4:1 compression ratio and a latency of a few milliseconds. For this event, more than 120 Nevion Virtuosos were used for the live 4K broadcast to billions of viewers via CMG’s China Central Television’s (CCTV) television station and website, as well as 70 4K movie theaters.
Nevion Virtuosos ensured the reliable TICO encoding and decoding of all 4K/UHD signals in Tiananmen Square from OB vans, on-site cameras in buildings and microwave links from vehicles and helicopters. The compressed signals were then transported between two master control rooms, four 4K studios and CCTV’s 4K playout system at different sites as 3G-SDI TICO streams using Nevion’s fiber transmitters and receivers. 4K PGM signals were also encoded by Nevion Virtuoso using lightweight TICO compression technology and sent back to two ultra-large LED screens in Tiananmen Square to provide real-time pictures for the audience on site.
