DVB-S Modulator with embedded Remultiplexer

Integrated solution for the distribution/regeneration of DVB-S services. The system is composed by a demultiplexer/multiplexer and a DVB-S modulator with RF output. Easily configurable through a UART serial port, allows the development of a complete and very compact modulation system.

Remultiplexer specifications:

ASI and SPI TS inputs
ASI and SPI TS outputs
Automatic recognition, analysis and demultiplexing of the incoming services
Visualization of the Input/Output TS bandwidth
Selection and removal of unwanted services
QoS (Quality of Service) function for the selected services
NIT (Network Information Table) insertion for a correct Bouquet generation
Automatic service monitoring and PID tracking for the desired services
Supports Service-ID remapping
Embedded DVB-Tables regeneration
Embedded remultiplexer for the DVB-S TS reconstruction
PCR restamper for a correct timing reconstruction
Non-volatile memory for system configuration
Easy configuration through asynchronous serial port with high-level commands
No need for additional programming on power-up

Modulator specifications:

QPSK Modulator, DVB-S (ETSI ETS 300 421)
