The RMG-300 is a dual-channel 4K media gateway card for Kiloview's Cradle RU01/RU03 rackmount chassis, bridging IP-based video systems and signal formats from a single slot-in module. It decodes and outputs dual-channel video via 3G-SDI (up to 1080p60) and HDMI 2.0 (up to 4K60), with H.264/H.265 real-time transcoding and protocol conversion across NDI HX, SRT, RTMP/RTMPS, RTSP, HLS and TS over UDP/RTP. It accepts up to 9 simultaneous IP stream inputs, each convertible into up to 4 output streams, and doubles as a lightweight streaming media server supporting up to 50 concurrent stream accesses for distribution or live streaming. Custom multiview layouts let several sources be combined into a single output.
