Single transmodulator

Single transmodulator

Transmodulator equipped with remultiplexing

DVBS/S2 - DVBT, with CI

Transmodulator generating one (two) COFDM multiplex from the multiplexing of the services available in up to 3 different TV SAT transponders.

These may be extracted from 2 different satellites (2 independent SAT inputs), or from a single satellite, using the headend's input loop.

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
  • Null packet insertion (“Stuffing”) allows the receiver (STB) to perform a faster scan
  • PID filtering allows the removal of undesired services from a Multiplex (enhanced occupation use); very interesting when combined with CAM use
  • S_ID editable to prevent the receivers (STB) in an installation from retuning when the output-Multiplex's services are modified
  • Editable Network_ID, Original Network_ID and Cell_ID allow the control of network identifiers
  • The encrypted satellite channels are transformed into free DTT services through the CI interface and the appropriate CAM module. Depending on the CAM type used (standard/professional), one or several services may be opened for free visualization
