XTS - Specifications
Article Index


  • to feed audio from remote locations into a satellite DVB-S platform
  • to feed audio into a terrestrial DVB-T platform from its initial implementation
  • to feed audio signals to CATV head-ends
  • to back-up existing audio channels over satellite
  • to extend existing audio programme distribution channels into DVB networks
  • to easily move existing audio channels to another (physical) location
  • to bring a number of DVB audio channels via an IP(Internet) platform over satellite (use gaps in excess bandwidth)

Special Features

  • The X.21 inputs accept MPEG audio from local codecs and standard contribution links (e.g. leased lines, microwave links or satellite links).
  • The auto-sensing function will automatically select either the MAIN or the BACK-UP input to receive the MPEG stream.
  • After initial programming, the XTS is self sufficient.
  • One or two converters in a 19“ cabinet of 1RU height only; even with redundant power supply.
  • A special pre-multiplexer combines over 100 XTS processed audio programmes into one DVB TS, thus better use is made of existing TS feeds and multiplexers.
