As 4K, the next generation of video resolution, comes of age, media organizations face the challenge of efficiently and cost-effectively delivering a more immersive, engaging visual experience to demanding audiences. To address the need for high-quality and reliable transmission of high resolution content, CESNET and its partners proudly introduce the MVTP-4K Modular Video Transfer Platform.

4K Gatewayis a rack-mounted device for low-latency real-time transmissions (4K30p contribution with JPEG 2000) of multiple high-definition video streams from HD, 2K up to 3D 4K over the Internet. From remote collaborative film post-production, the streaming of live events in Digital Cinemas to eLearning in medicine, this advanced technology overcomes bandwidth constraints to provide a truly flexible and efficient distribution platform for high-end content.

4K Gateway has been developed by CESNET in direct partnership with ACE, an independent post-production company, and Visual Unity, a leading broadcast and multiscreen Systems Integrator. This successful collaboration has enabled CESNET to test 4K Gateway directly in its key target markets, sharing knowledge and best working practices to make the breath-taking image quality of 4K native resolution more accessible.
