Transmodulator generating two COFDM multiplexes 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.
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
