WDQ-3180 QPSK Digital modulator converts input data streams into frequency signals; it meets to DVB-S standard. Signals from MPEG-II compact encoder or multiplexer was sent into QPSK modulator. It is according to DVB standard such as interlacing, RS error correction encoding, etc. After up-converting into the range of TV channels, signals can be transmitted through HFC and MMDS networks. It’ s widely used in digital TV, data broadcasting, VOD, Internet, video conference etc. The WDQ-3180 has very convenient and friendly management interface, the user can complete all operation via local keyboard and LCD display on device, or access through the Ethernet port on device.

◇ Re-multiplex for all DVB program Transport
