JXDH-6405 DVB-T Modulator

Detailed Product Description

Description:
DVB-T/H Modulator supports DVB-T/H standard channel coding and modulation parameters 

Outline
DVB-T/H Modulator supports DVB-T/H standard channel coding and modulation parameters. A/V signals compressed and coded via MPEG-II and be multiplexed and processed together with other data stream, then send to DVB-T/H modulator. Modulator channel coding process is full according to DVB-T/H 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 applications.
