Extron SMP 351 80GB H.264 Streaming Media Processor 60-1324-01

Product Overview

The Extron SMP 351 80GB is a 1U rack-mount H.264 recording and streaming media processor for professional AV environments. It accepts HDMI, component, composite, and optional 3G-SDI signals, applies two-window processing to selected sources, and can record and stream simultaneously at two different resolutions and bit rates. The 80 GB internal SSD provides up to 16 hours of local storage at 10 Mbps. Available at Creation Networks.

Product Description

The SMP 351 80GB processes two high-resolution AV sources from up to five available inputs: three HDMI (one with loop-through), component video, and composite video — with an optional 3G-SDI input. Channel A accepts HDMI or component/composite sources with a buffered loop-through to a local display. Channel B accepts composite, component HD, and HDMI. Both channels support computer-video formats from 640x480 to 1920x1200 and video from 480p to 1080p/60.

Sources are combined using flexible two-window arrangements — full screen, side-by-side, picture-in-picture — with up to 16 layout presets. H.264/AVC encoding produces MP4 (M4V) files stored to the internal 80 GB SSD, front or rear USB drives, or a defined network share via CIFS/SMB or NFS. Simultaneous streaming at two resolutions and bit rates supports overflow rooms, confidence viewing, and archive workflows. Push (RTMP, RTMPS, MPEG2-TS/UDP, Direct RTP) and pull (RTSP, HTTP-tunneled) streaming protocols are supported. FlexOS applications add integrations with Panopto, Kaltura, YuJa, Opencast, iCalendar scheduling, and FTP/SFTP file publishing. Available at Creation Networks.
