4K digital video offers approximately four times the resolution of HD television format, and 24 times that of a standard broadcast TV signal. This streaming device allows film, post production and visualisation companies to harness the power of 4K over unlimited bandwidth and distance in collaborative environments.
Visual Unity is a linear and multiscreen systems integrator. To develop 4K Gateway, Visual Unity worked in conjunction with Czech academic association CESNET and Prague-based independent post-production facility ACE.
Operating over photonic networks or shared internet, 4K Gateway offers very low latency of less than 1 ms plus networking delay. Higher buffering can be optionally selected to compensate high network jitter or for special applications. 4K Gateway uses industry standard HD-SDI interfaces for eight video inputs and eight video outputs, all working simultaneously in multi-channel full-duplex operation. Each HD-SDI channel can operate in full mode (all dark areas transmitted) or view mode (dark areas not transmitted). The latter allows the transmission of eight HD-SDI channels over a single 10 Gigabit Ethernet interface, thus enabling uncompressed 3D 4K or 4K RGB (4:4:4) transmissions.
Visual Unity and its development partners have already put 4K Gateway through its paces on a series of projects. These include a remote real-time low-latency collaboration on color grading of 4K video content, which was demonstrated over a distance of more than 6200 miles (10000 km) from Prague to San Diego, California. Another successful project saw 4K Gateway employed to remotely access scientific visualisations using low-latency real-time interactive navigation in a remote 3D building model.
