Czech Educational and Research Network

The Czech Educational and Research Network, known as CESNET, operates as a national e-infrastructure consortium linking universities and research institutes across the Czech Republic. Its open-source UltraGrid platform addresses the demanding requirements of live event production, distance learning, medical imaging, and collaborative research by delivering uncompressed or visually lossless 4K/8K video and multi-channel audio over commodity IP networks at sub-frame latency. Engineers, broadcasters, and educators use the software to create low-latency contribution links, interactive classrooms, and remote instrument access, relying on its support for HDR, high frame rates, and encrypted SMPTE ST 2110, NDI, and RTP workflows. Extensive codec options, hardware acceleration, and fine-grained network tuning allow the tool to adapt to everything from high-capacity regional loops to constrained international circuits, while built-in diagnostics and multicast failover protect mission-critical streams. CESNET’s ongoing development is driven by real-world campus, broadcast, and telemedicine trials, ensuring that UltraGrid stays aligned with emerging standards for 10-GigE, 100-GigE, and beyond. The publisher’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest versions and enabling batch installation of multiple applications.
