Nevion supports CCTV’s 4K/Ultra HD transmission

Already a user of Nevion’s VideoIPath and eMerge solutions, China Central Television (CCTV) has added the Virtuoso solution for 4K/UHD signal transmission between studios

With an aim to increase its use of 4K/Ultra HD (UHD), Chinese national broadcaster China Central Television (CCTV) has chosen to deploy Nevion’s Virtuoso software-defined media nodes for the transmission of 4K/UHD signals between studios.

The deployment of Nevion’s Virtuoso will be used to encode 4K/UHD signals to fit on a bandwidth equivalent to a single 3G-SDI signal, while using TICO compression technology. This will enable CCTV to use its existing 3G-SDI infrastructure to route and transport the 4K/UHD signals, reducing the need to invest in additional capacity to support the higher resolution, said Nevion.

Furthermore, the solution also supports signal transportation over IP –both SMPTE ST 2022-6 and ST 2110 – allowing CCTV to eventually transition to an IP infrastructure.

The project builds on an existing relationship between Nevion and CCTV, which has been a user of Nevion’s VideoIPath orchestration and software-defined network (SDN) control software, and eMerge switches as the core of its SDN system since 2017. CCTV has deployed the system for several events in China, including the Spring Festival Gala and the Boao Forum for Asia, as well as the 2018 FIFA World Cup.

Hans Hasselbach, CCO for Nevion, concluded: “We are thrilled that CCTV has extended our existing relationship and taken on Nevion Virtuoso in addition to Nevion VideoIPath and our eMerge switches. We look forward to helping CCTV as they make the move to using TICO for 4K/UHD coverage.”
