Streaming Input Card for DM Switchers

The DMC-STR is an input card designed for use with any card-based Crestron® DigitalMedia™ Switcher. It provides one streaming input, with associated HDMI® and analog audio outputs. The streaming input receives a single H.264 video stream over an IP network from another DM® switcher, an IP camera, or a streaming server (Crestron CEN-NVS200 or similar[1]).

DMC-STR features include:

  • Modular input card for a DM-MD8X8, DM-MD16X16, or DM-MD32X32 switcher
  • Provides a single streaming input
  • Converts the incoming stream to HDMI® for distribution via DigitalMedia™
  • Allows high-definition AV signal distribution over IP with no distance limitations
  • Supports streaming at resolutions up to 1080p30 and bitrates up to 25 Mbps
  • Employs high-quality H.264 video and AAC audio decoding
  • Includes a stereo analog line-level audio output with volume control
  • Allows extraction of stereo 2-channel audio signals
  • Includes an HDMI® output for pass-through of the decoded signal
  • Supports streaming via the Control LAN or a dedicated Content LAN
  • Occupies a single DM switcher input card slot
  • Provides a streaming receiver solution using the optional DMCI card interface[1]
