The PMX41 is broadcast DVB-ASI multiplexer capable of combining up to 4 different ASI streams into one Multi Program Transport Stream (MPTS). The PMX41 MUX is easily controlled using a front panel interface, or a remote control based software tool.

A typical application of PMX41 would involve combining several encoders into one DVB-ASI stream that would then be sent to a modulator for further RF distribution. A low cost and reliable unit should be essential in any broadcasting headend.

PMX41 Description

    • 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 and processing 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 stream
    • User 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
