The PMX41 is a four input port, one output port MPEG-2 compatible multiplexer. It handles SD or HD program content. It handles MPEG-2 and MPEG-4 programs that comply with the basic MPEG transport stream specification. All of the PMX41 inputs and outputs comply with the DVB-ASI industry standard for signal connection within the headend. The PMX41 creates a single or multiple program transport stream output from one or more of the inputs which can accept either multiple or single program transport streams.

The PMX41 offers the ability to combine smaller transport streams into one larger stream for further processing or modulation into a hospitality, MDU or small cable systems. The PMX41 can also drop programs or parts of a program (secondary audio for example) in any input stream to minimize output stream size to allow the stream to fit into 64 QAM or 256 QAM modulated RF channels or to remove undesired programming from the distributed stream. The use of the PMX41 allows more programming in limited RF bandwidth where channels are not available or where cost of modulation equipment is a concern.

Typical applications for the PMX41 are to place off-air programming on a QAM cable plant, using 8VSB demods with ASI output such as the MPD-ASI. Satellite receivers with ASI output can also feed the PMX41 to allow multiple SD or HD programs to be placed in one modulator, reducing cable plant bandwidth demands.


  • Accepts up to 4 MPEG-2 or DVB transport streams to be combined on a single ASI output
  • Inputs may be single or multiple program streams up to 100 Mbps each from common MPEG sources such as encoders, other multiplexers, demodulators, receivers and servers, in DVB-ASI format
  • Output is single or multiple program transport stream of up to 100 mbps in DVB-ASI format suitable for modulation or other MPEG transport andprocessing equipment
  • Passes DVB information and assembles SDT, NIT, EIT tables when in incoming streams' tables
  • Simple to use front panel menus allows scan of inputs including data rates of the incoming material to avoid oversubscribing the output streamUser selects the programs, video, audio content from each input to be passed on to the output
  • Constant output rate selectable from 5 mbps to 100 Mbps
  • Ethernet remote control with provided utility to augment front panel setup
