Single transmodulator DVBS/S2 - DVBC (QAM Annex A) equipped with CI Televes

Transmodulator that generates a QAM Multiplex from the services originally delivered in a TV SAT transponder. Televes 563501

Reference televes-563501

Brand Televes

Transmodulator that generates a QAM Multiplex from the services originally delivered in a TV SAT transponder.

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)

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 reproduction
