Matrox Monarch EDGE

Name: Matrox Monarch EDGE
Brand: Matrox

SDI H.264 4:2:2 10-bit encoders and decoders for remote production (REMI)

Monarch EDGE transports synchronized video, audio and metadata from the venue to the production center. The E4 encoder accepts up to four SDI cameras, the D4 decoder returns them to SDI, and the S1 model simultaneously encodes and decodes an HD signal for program return. Tally, talkback and genlock are built in, and transport runs over SRT, RTMP or MPEG-2 TS.
