Product Description

Latest networking devices 45MHz to 870MHz CATV rf if modulator
Summary

CATV rf modulator is the main equipment CATV digital head-end, receiving DVB transport streams which come from coder, multiplexer, DVB gateway, scrambler, video server etc. It does signal processing like RS coding, convolution interleaving and QAM modulating, providing IF/RF output.

Features
Complying DVB standard signal channel coding.Support full range variable data rate, bandwidth and QAM mode Data stuffing super buffer (optional),anti-burst code streamPID filter, re-reflection, PSI,SI information synchronal updating possible.Automatically code stream stuffing and empty pocket deleting.Code stream real-time monitoring, empty pocket filteringSupport NIT table modifyingreal-time code stream monitoringPCR adjusting, output symbol rate variable:1-7Ms/sFixed or agile channel output;Providing ASI and Ds3 input port and output port (optional)Providing RF output monitoring port(-20dB)Local or Remote administration possible.LCD display, flexible in operatingHigh reliability design, stable in running
