SMP 351

H.264 Streaming Media Processor

The SMP 351 is a high performance recording and streaming processor for capturing and distributing AV sources and presentations as recorded media or live streaming. It incorporates Extron’s FlexOS®, a flexible platform for automating system operation. Accepting HDMI, component, composite, and optional 3G-SDI signals, it applies two-window processing to the selected sources. The SMP 351 can record and stream simultaneously and can stream at two different resolutions and bit rates concurrently using a range of transport protocols and session management options. Comprehensive control and configuration features make the SMP 351 integration-friendly, and easy to control and operate. Requiring no licensing fees, the SMP 351 has a low cost of ownership, making it a cost-effective solution for delivering presentations to a larger audience.
