Lawo provides mobile IP video solution for CCTV


China Central Television (CCTV) has installed the country‘s first full mobile IP video system for video production, providing the Lawo V__matrix software-defined IP-routing, processing and multiviewing platform as its core infrastructure. Working in conjunction with Lawo China and video partner Acro-bright, CCTV commissioned systems integrator, Beijing Yutian, to complete the work. The SI has integrated a number of Lawo projects for CCTV in HD/UHD OB vans, audio SCRs and studios at CCTV’s Beijing headquarters.

Work on the UHD 4K mobile studio installation – originally contracted to play a central role during the Tokyo 2020 Olympic Games broadcasts – began in January 2019 under the supervision of the CCTV production department. The project’s multiviewer design is based on three Lawo V__matrix systems using 19 C-100 core processing modules and 19 Virtual-Module installations using the Lawo vm-dmv IP multiviewer.

Twelve Sony UHD camera channels are fed into an EVS server to achieve slow motion instant replays and effects in full HD resolution for the benefit of sports broadcasts and other high-end content creation works. A spine-leaf topology IP network employs Huawei switches for the infrastructure backbone with two CE8850 switches for the redundantly designed core and four CE6865 switches as leaves. Sony vision switchers and cameras complete the setup.

“Lawo turned out to be not only strong in audio consoles, but also in IP video processing,” commented a CCTV video engineer. “The success of this project was only possible with Lawo, as the vm-dmv multiviewer solution, with its 12G single link for both IP and base-band signals, offers true 4K performance with extremely low latency.”

CCTV has been using Lawo technology for the past 13 years, and has now extended its trust to the manufacturer’s video technology to provide an advanced IP solution for a 40G network environment
