The PMV 1841 is a compact quad split multiviewer ideal for applications needing basic quad split multiview capability into an HDMI monitor. Four SDI inputs are supported with a single HDMI output. The module has three basic modes of operation: Quad Split - All four inputs are arranged into a fixed quad display. Each input can have the monitoring tools (or on screen overlays) individually configured. Full Screen - One of the four inputs is displayed full screen with the user configured monitoring tools. In this mode 2 channels embedded audio from the selected SDI input is embedded into the HDMI output. 4K Monitoring - The module can be used to monitor 4K (12G) signals. The four SDI inputs are "stitched" together to make a full frame for monitoring. The 4K image is down converted to HD for display (4K monitor not required).
