The DMC-STRO is an output card designed for use with any card-based Crestron® DigitalMedia™ Switcher. It provides a single streaming output to allow for the distribution of high-definition video and stereo audio to Crestron touch screens, mobile devices, digital signage displays, remote buildings, and global offices over Ethernet and the Internet.

High-performance H.264 streaming capability enables enterprise-wide distribution of HD content over an IP network. Streaming expands the capabilities of a DM® system to remove all distance limitations and allow distribution to virtually any device — anywhere in the world. Streaming is an essential component of any complete DM system for the routing of signals to Crestron touch screens, to another DM switcher, or to any device via a streaming receiver. Large-scale streaming to computers and mobile devices can be facilitated through integration with a streaming media system such as Wowza® or Kaltura®.

Streaming via a DM switcher affords the ability to distribute any combination of sources to virtually any device anywhere. The DMC-STRO supports streaming at resolutions up to HD 1080p and bitrates up to 25 Mbps. Built-in scaling enables fast, trouble-free switching between sources of any type or resolution.[1] Audio support includes stereo signals, as well as multichannel surround sound signals downmixed to stereo via a “DSP” type DM switcher input card.[2] High-quality video and audio is maintained using high-performance H.264 video and AAC audio compression. The encoded video and audio can be output as independent RTP streams or encapsulated in an MPEG-TS (MPEG-2 Transport Stream) container. HDCP management ensures that protected content cannot be distributed via streaming.

The DMC-STRO’s streaming output is actually fed internally by two separate switcher outputs, allowing any two of the switcher’s input sources to appear picture-in-picture or side-by-side in a single stream. Instant, single-frame switching between two full screen images is also possible. The audio signals from both input sources can also be mixed, allowing both signals to be heard simultaneously.

DigitalMedia provides many deployment options to address a wide range of streaming applications and accommodate each organization’s specific IT requirements. DM supports both unicast and multicast streaming, with or without RTSP (Real Time Streaming Protocol). Streaming connections can be configured to stream directly to one or more specific IP addresses, or to use RTSP to manage the configuration of numerous connections automatically. The streaming output can be configured to stream via the dedicated “CONTENT LAN” port on the DMC-STRO, or via the DM switcher’s LAN port, allowing the option to isolate control and content onto separate networks or combine them on a single network.

To configure a DM switcher complete with input and output cards, cables, and other peripherals, please use the online DigitalMedia Switcher Configuration Tool.

Are you upgrading an existing DM switcher that has older “multi-gang” DMCO-series output cards? Use the online Output Card Additions and Upgrades Tool to update your existing output cards and switcher to the new “single-gang” output card format.
