The Smart Videohub CleanSwitch 12 x 12 6G-SDI from Blackmagic Design is a mixed-format router with 12 6G-SDI inputs and 12 6G-SDI outputs, routing any combination of SD, HD, Ultra HD 4K and DCI 4K video. Its CleanSwitch design re-times SDI feeds so every switch happens between frames, and it supports both 4:2:2 and 4:4:4 colour sampling with 10-bit processing for smoother gradations. SDI reclocking runs on every input, with a built-in LCD and spin knob for direct control alongside push buttons on the front panel. Ethernet gives remote control over a network, and Videohub control software is included, all housed in a 1RU frame suited to a large broadcast system or a portable mini rack for a live production.
