WDH-1520MX

Re-Multiplexer and Scrambler Module


WDH-1520MX/DX is a series of high density advanced DVB transport stream re-multiplexer and scrambler modules. It can receive SPTS and MPTS from both GbE and ASI input ports. By using the user friendly web control interface, the input TS is demuxed to SPTS, then routed to the ASI and GbE output ports to build new SPTS and MPTS with PSI/SI regeneration or pass through. It can support up to maximum 256 PID or 32 TV services per TS with re-mapping, bypass, filtering functions. PCR jitter is improved by PCR correction and re-stamping features. As an advanced option, WDH-1520MX/DX can provide with DVB scrambling functions. It can support BISS-1, BISS-E and Simulcrypt modes by using the DVB common scrambling algorithm and built-in CW generator. With its multiple TS over ASI and IP input and output ports, flexible configuration and powerful TS processing ability, WDH-1520MX/DX is a key routing equipment that links the TV sources from professional IRDs and encoders to DVB modulators in the headend system.
