DVB-C/T/S modulator board can be used for designing a variety of converters, modulators, transmodulators and other digital broadcasting equipment. A plenty of devices can be used as a source of the input transport stream:
- DVB-S/S2 receiver;
- DVB-C/T/T2 receiver;
- MPEG encoders;
- TS multiplexers;
- ASI-to-DVB TS converters;
- IP-to-DVB TS converters.
The RF output signal can be fed to combiners, additional filters or directly to television transmitters or networks. Management, monitoring and configuration of the modulator board is provided via RS-232 PC interface or TCP/IP protocol (via IP-UART Control Module).
The main advantages are:
- High quality of the modulated signal;
- Fine-tuning possibility;
- Small size and low power consumption;
- Greater flexibility.
