Proposition 65 Warning for California Residents

The Crestron® DM-TXRX-100-STR is a compact H.264 streaming encoder/decoder designed to enable the distribution of high-definition AV signals over an IP network. Configurable as either a transmitter or receiver, it provides a perfect complement to a DigitalMedia™ switcher with one or more streaming inputs or outputs, and can also be used to add streaming capability to other switchers and devices. By transporting all video, audio, control, and power signals through a single PoE LAN connection, the DM-TXRX-100-STR delivers the perfect solution for those applications where new or dedicated wiring cannot be installed.

H.264 Streaming

High-performance H.264 streaming capability enables enterprise-wide distribution of HD content over a wired or wireless IP network. Streaming expands the capabilities of a DigitalMedia system to remove all distance limitations and facilitate distribution to virtually any device — anywhere in the world. Streaming also allows for the utilization of existing network infrastructure to overcome situations where the installation of new or dedicated wiring may not be feasible.

The DM-TXRX-100-STR supports streaming input or output at resolutions up to HD 1080p and bitrates up to 25 Mbps. High-quality AAC audio compression is employed to handle 2-channel stereo audio with full frequency response. The encoded video and audio can be transmitted or received 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.

Streaming via the DM-TXRX-100-STR provides many deployment options to address a wide range of streaming applications and to accommodate each organization’s specific IT requirements. Both unicast and multicast streaming is supported, 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.

In addition to H.264, the DM-TXRX-100-STR can also receive and decode MJPEG streaming video.

HD Streaming Transmitter

As a streaming transmitter, the DM-TXRX-100-STR can be installed beneath a table, inside a lectern, or attached to a wall, allowing a laptop computer, camera, or other media source to be connected via HDMI® and streamed out over an Ethernet LAN, WAN, or Internet connection. The high-quality H.264 encoded signal can be routed to the streaming input of a DM® switcher or another DM-TXRX-100-STR, or it can be viewed on Crestron touch screens, digital signage displays, computers, mobile devices, and other compatible equipment. Password protection allows administrators to control who can view the streaming signal. Built-in scaling ensures trouble-free handling of sources with any resolution up to Full HD 1080p60, and allows for streaming at any resolution independent of the source resolution.

HD Streaming Receiver

As a streaming receiver, the DM-TXRX-100-STR decodes the streaming signal from a DM switcher, IP camera, or other streaming source and outputs it as HDMI to feed the input of a display device, AV receiver, or switcher. Its low-profile, surface-mountable design allows the DM-TXRX-100-STR to be mounted discreetly behind a flat-panel display, above a ceiling mounted projector, on an AV cart, or inside an equipment rack. Decoding of H.264 and MJPEG formats is supported.

Device Controller

The DM-TXRX-100-STR includes built-in RS-232 and IR control ports to allow for programmable control of the connected display, camera, and other devices. Additional control capability is afforded by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Via its Ethernet connection to the control system, the DM-TXRX-100-STR provides a gateway for controlling the display or source device right through its HDMI connection, potentially eliminating the need for any dedicated serial cables or IR emitters.

Confidence Monitor Output

In transmitter mode, the streaming output signal is also made available at the HDMI output, allowing the streaming output signal to be viewed locally on a video monitor.

Text Overlay

On-screen display of dynamic or fixed text allows for labeling of the video image, or the display of instructions, schedules, announcements, alerts, and other messaging.

Web-Based Setup

Built-in Web pages facilitate setup of the DM-TXRX-100-STR from a laptop, whether running standalone or connected to a DM switcher. Extensive setup, control, and monitoring of the device is also provided through integration with a Crestron control system.

Low-Profile Installation

The DM-TXRX-100-STR mounts conveniently to a wall, ceiling, or other flat surface. Its compact, surface-mountable form factor fits easily behind a flat panel display, above a ceiling-mounted projector, beneath a tabletop, or inside a lectern or other furniture. It can even be attached directly to a single rack rail in the back of an equipment cabinet. It can be powered using the wall mount power pack (included), or via PoE (Power over Ethernet) for a true one-wire solution. All connections and LED indicators are positioned on the top and bottom, ensuring optimal access and visibility for a clean, serviceable installation.
