    IQHCO50: 3G/HD/SD-SDI Signal Protection Module Datasheet (GVB-1-0763A-EN-DS) File size: 385.5 KB, posted Jan 09 2019
    The IQHCO50 from Grass Valley, a Belden Brand, provides backup protection for SDI signal paths using video and audio input error monitoring, resulting in automatic change-over to a backup feed on error state detection. A powerful rules engine is available to provide logical conditions for auto-switching, while GPI inputs and card edge control can force the unit to switch independent of signal state. Features include three selectable inputs and a dedicated TPG input, alongside monitoring of the unselected inputs for video and audio signal confidence.
