FLEXMod 301
DVB-S/S2/T/T2 to DVB-C Transmodulator with embedded Remultiplexer
Integrated solution for the redistribution/regeneration of DVB-S/S2/T/T2 services into DVB-C. The system is composed by a demultiplexer/multiplexer and a COFDM modulator with RF output. Easily configurable through a UART serial port, allows the development of a complete and very compact A/V distribution 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.
  • LCN (Logical Channel Number) insertion 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.
  • REmbedded DVB-Tables regeneration.
  • Embedded remultiplexer for 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.
