Transmodulator with remultiplexado Twin DVBS/S2 – DVBT with…

Transmodulator that generates two COFDM multiplexes from the multiplexing of services available in up to 3 different TV SAT transponders. These can be extracted from 2 different satellites (2 independent SAT-IF inputs), by means of the input loop to the header itself.

Stands out for
Total or selective elimination of the services present in the received transponder, so that they are not detected (and memorized) by the receivers (STB)
Editable TS_ID, which facilitates the detection of programs / services in the receiver (STB) because they perform the scanning of channels based on this identifier
LCN (Logical Channel Number), allows to assign to the services present in the output an LCN, which facilitates the ordering of the channels in the receivers (STB)
It provides information about the occupation of each service and the total occupation of the output, which allows to optimize the distributed services
Remotely controllable with the CDC (Head Control)
Features
Insertion of null packages (“Stuffing”), allows faster scanning by the receiver (STB)
Filtering PID, allows to eliminate within a multiplex, those services that do not interest (use of occupation), very interesting with the use of CAM
S_ID editable, to avoid retuning of the receivers (STB) of an installation when the services of the output multiplex are changed
Network_ID, Original Network_ID and Cell_ID editable, allows to control the network identifiers
Through the CI interface and the corresponding CAM module, the coded satellite channels are transformed into free DTT services. Depending on the CAM used (standard / professional), one or several services can be opened for open viewing
