ASI to QAM CATV RF Modulator

It provides a more powerful receiving ability of various Transport Streams that come from an encoder, multiplexer, DVB gateway, scrambler and video server. In addition, the modulator also has the ability of outputting RF while simultaneously disposing the TS by RS encoding, convolution interlacing and QAM modulating. This device supports local and remote control through NMS software. This unit has wide array of functional uses from Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.
