Datavideo DATA-KMU100 (DATAKMU100) KMU-100 UltraHD to HD Multiviewer Converter. Shortlisted for the IABM's 2016 Game Changer Award, and winner of 3 independent awards at NAB 2016, the KMU-100 is a unique 4K multi-camera production solution that delivers multiple virtual full HD (up to 1080p) scaled camera angles with minimal installation cost and simple operation.
The basic concept is straightforward: the output of a single 4K/UHD camera is connected to KMU-100, which then displays up to four 16x9 user-defined cropped windows that are sent out as four separate HD signals through HD-SDI. These user defined windows can be scaled to zoom in on a particular subject that you would like to highlight on the 4K signal. An additional 4K camera can be connected to allow up to eight defined outputs from the two 4K signals.
In essence, with KMU-100 a single 4K camera can be used to deliver a true 4-camera HD production, without the need to install, manage, operate...
