Secure Datacasting Gateway


Secure Datacasting Gateway – FlexStream MX-400SR

Datacasting Solutions are a mechanism for inserting file data into unidirectional broadcast transport streams, distributing those streams over terrestrial, cable, or satellite TV transports, and assembling the streams into files at the target destination. This technology scales extremely well and is ideal when many targets are receiving the same file data. Our advanced datacasting solutions include forward error correction, targeting, content protection, IP encapsulation, adaptive bitrate encoding, and many other techniques to improve the reach and utility of our datacasting solution. This technology is commonly used with satellite and terrestrial broadcast transmissions but is also useful in small venues such as private cable networks.

The FlexStream MX-400SR is based upon the MX-400 and specifically configured for datacasting. It replaces the iconic 2U FlexStream-SR, featured in this PBS promotional video, as West Pond’s datacasting broadcast interface. This third generation device was designed with station/network managers, engineers, and datacasting providers in mind. This equipment is not just a datacasting server, but a gateway for all future datacasting needs. A single place where station engineers can manage and monitor datacasting provider’s use of station bandwidth. If awards were given for datacasting devices, the MX-400SR surely we receive one. Not convinced, check out some of our use case applications below, or download and explore the MX-400SR user manual.

The FlexStream MX-400SR is specifically designed for:

  • Broadcast and Satellite data insertion (datacasting)
    • Install at broadcast or satellite uplink facility or remotely feed the transport via IP
    • Provides simple (FTP hotfolder) or sophisticated (REST API) data input mechanisms
    • Creates data carousel streams from files
    • Prioritizes, encodes, signs, targets, and signals the data as specified
    • Manages multiple carousels and multiple datacasting providers
    • Integrates streaming sources from MX-400IO devices
    • Multiplexes all datacasting providers into one or more output streams
    • Supports opportunistic insertion and CBR from low bitrates to full transport speeds
    •  Transmits large files, small files, and streaming media
    • Transmits folder structure
    • Unlimited number of files
  • Real time monitoring
    • Track via ASI (input) or RF (broadcast monitor tuner)
    • Confirms data in = data out.
  • Experience
