Highlights
  • Total or selective removal of the services present in the received transponder, to avoid them being detected (and memorized) by the receivers (STB)
  • Editable TS_ID, which makes programme/service detection easier on the receiver (STB), since the channel scan is based on this identifier
  • LCN (Logical Channel Number) allows the assignment of the services present in the output to an LCN, which makes the ordering of the channels easier on the receivers (STB)
  • Provides information regarding both the occupation of each specific service and the global output occupation, which allows the optimization of the services being distributed
  • Can be remotely controlled using CDC (Headend control)
  • Device monitoring and signal status LEDs

Main features
  • Two independent tuners allowing more than 14 services per module
  • Two output stages with packet generation above 6 MHz bandwidth
  • Equipped with an input matrix to allow any input signal to be processed by any of the demodulators
  • Output up to 1024 QAM
  • Null packet insertion (“Stuffing”) allows the receiver (STB) to perform a faster scanning
