JXDH-6405 DVB-T Modulator converts input data streams into frequency signals, it meets DVB-T standard. Signals from MPEG-II compact encoder or multiplexer was sent into DVB-T modulator. According to DVB-T standard, such as FEC, interlacing, RS error correction encoding, etc. After IF processing and up-converting into the range of TV channels, signals can be transmitted through HFC and MMDS networks. Its widely used in digital TV, data broadcasting, VOD, Internet, video conference SV.
