Dvb-t Modulator - Mpeg-2 Encoding, Cofdm Modulation, Advanced Pid Filtering | Real-time Bit Rate Monitoring, Rs Coding, Nit Mapping, High Snr Performance

DVB-T Modulator support DVB-T standard channel coding and modulation parameters, A/V signal compressed and coded via MPEG-2 and be multiplexed and processed together with other data stream, then send to DVB-T Modulator. Modulator channel coding process is full according to DVB-T technical specifications and achieve energy proliferation, interweave, FEC coding, RS coding, symbol mapping, filter matching etc. After that modulated by COFDM and output IF. IF through built in up-converter generate the required RF output. Widely used for terrestrial digital television broadcasting, mobile data broadcast and digital broadband application.
