DVB-S/S2/C/C2 to DVB-T Transmodulator with embedded Remultiplexer
Integrated solution for the redistribution/regeneration of DVB-S/S2/C/C2 services into DVB-T.
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
- Embedded 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
- COFDM Modulator: DVB-T/H ETSI EN 300 744 V1.5.1 (2004-11)
- Selectable RF power output up to -7dBm
- Enhanced digital filtering for improved adjacent channel packing
- Frequency range 0 - 500 MHz RF out through internal 1 GHz DAC
- Image signal 500 -850 MHz still usable for many applications
