FlexStream Smart Headend Series


The Customizable MX-400

Each product in the FlexStream MX-400 series addresses the specific needs of its respective market. West Pond has created solutions for Hospitality, Senior Living, Stadiums & Arenas, and Broadcast Infrastructure as well as many others.

If none of our existing hardware solutions meet your exact needs our engineering services team can work with you to create a custom configuration.

For a list of available options see the features, architecture, and specs tabs below. For a list of available preconfigured models, and the features they provide, see the product comparison grid below.

Prebuilt, or design your own

We provide a nice collection of preconfigured units, but our specialty is our creativity. Check out our list of available input and output modules, then contact us about building your own configuration.

FlexDM Remote Management

Use FlexDM to manage West Pond devices from anywhere on any device. Create and manage a video playback channel at multiple sites. Check the status of a customer’s RF network. Turn one or more TVs on or off. All this through one web site.

Compact, All-in-one Solution

The MX-400 makes TV headend simple. Other solutions require modulators, capture devices, encoders, multiplexers, TV tuners, Ethernet switches, and lots of cabling. The MX-400 has it all.

FlexStream MX-400

Choose a pre-built configuration, or custom configure your MX-400 to:

  • Create TV channels that convert TVs into digital signs.

MX-400 Base Model

The MX-400 is the most versatile member of West Pond’s smart headend family. The 1RU form factor supports 4 GigE network ports, four exposed, and 4 internal expansion modules. These expansion capabilities provide a wide variety input sources and output transports for the MX-400 broadcast quality multiplexer to process. Video sources include HDMI, Component, Composite, HD-SDI, DTV tuners, ASI, Cameras, and IPTV. Outputs include IPTV, ASI, and DTV modulated RF. West Pond provides a variety of market specific software packages including the TS (transport stream multiplexing), CC (channel creator), HY (hospitality) and the ST (stadium). Available software features include video streaming, video capture, video encoding, HTML video wrapping – digital signage, SPTS/MPTS multiplexing and grooming, IPTV and cable TV streaming, in-house cable network monitoring and troubleshooting, display controls, and more. The MX-400 can be configured to perform the functions of one, many or all of the following traditional headend components.

Video Server / Streamer: Load 30 hours or more of video files onto the MX-400 and create custom TV channels via our built in video server. Create a looping playlist or schedule playback at specific times. Manage channels and video content on one or more systems using FlexDM.

Video Encoder (HDMI / Component / Composite / S-Video): Capture video and audio from any of these ports and encode it to broadcast quality standards. This box supports h.264 and MPEG2 video and a variety of audio formats.

Digital Signage Player: The HTML5 video wrapper combines video streams with HTML5 media to create a dynamic multi-media experience on a TV channel for viewing on one or more TVs without a digital signage player. This powerful tool is made simple through presentation templates provided by West Pond. See https://westpond.com/templates for a list of recent templates.

Cable / Terrestrial / Satellite TV Set Top Box Receiver: Integrated DTV tuner replaces shelves of clunky receivers and messy wiring.

Demux-Remux Multichannel Multiplexer: Our integrated scalable broadcast quality multiplexer replaces the need for external rack mounted multiplexers.

GigE Switch: 4 internal GigE ports reduce the need for and external managed switch and simplify wiring in a mixed LAN environment. Our system can communicate with your IPTV LAN, your in-house LAN, security cameras, and other devices while still leaving spare ports to manage the system.

Multi-channel modulator: The MX-400 supports up to 5 frequency and modulation agile modulators.

Monitor TV / IRD: The MX-400 front panel display reduces the need for IRDs or diagnostic TVs. The front panel QVGA screen provides a live view of every multiplexer input. The RF monitor tuner scans all channels simplifying installation and enabled diagnosing and resolving issues remotely.

Display controller: Every display on your in-house TV network can now be controlled via the integrated display control system. A display control device is installed at the TV that the MX-400 uses to control TV functions such as power, volume and channel. Conceptually this feature is similar to having a remote control that simultaneously sends commands to one, many, or all of your TVs.
