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
Stream related application
◇ DVB-S modulation
