The dLNB product range uses dCSS (Digital Channel Stacking System) which is equivalent to having a whole SAT processing headend the size of an LNB.

This technique consists in processing the transponders of a satellite and positioning them in the SAT band according to the installation requirements.

Two operation modes are available:.

  • Dynamic mode (default): each SAT packet that is generated is assigned a network user, who is able to modify the packet contents at will with a compatible STB. This mode is limited to 24 User bands. Until the firs dCSS comand is delireved to the LNB, it will behave in alignment mode for the Eutelsat Hotbird 13E satellite, showing at the output 5 transponders for the VL polarization arround transponder V16 (11508Vi, n the best case scenario were pointing with a DVB S2 capable meter) and a the transponder 12596V  (V94, DVB S transponder if  only a DVB S meter is available).
  • Static mode (only by demand): up to 32 packets can be generated following a simple SAT distribution. Any TVSAT receiver can capture signals when working in this mode

The dLNB complies with standards SCR I and SCR II (dCSS). Both have the same type of application, dCSS being a second generation of the first one. This feature makes dLNB compatible with the STB implementing SCR and with new generation dCSS STB.

Main features:

  • A whole satellite on a single cable
  • Adaptable storable configurations
  • The dLNB has operation modes that facilitate the dish pointing process
  • A given configuration may include some transponders set as SCR I  and some others set as dCSS, based on the existing STB for that installation.

Highlights:

  • dCSS technology adds value to a SAT distribution
  • Using a single cable reduces the complexity of the installation
  • Configuration is flexible and scalable
  • Compatible with SCR I versions
  • Pre-configured references
