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.
