1.4 Multiplexer/ Re-multiplexer/ PID filter

A multiplexer has been integrated into the EMA device for processing the incoming transport stream. On condition that in this transport

stream (requiring forwarding) an adequate transmission rate is available, or additional transport volume is achievable by raising the

transport stream bit rate, new services and/ or program components can be added.
Depending on the configuration of the 4 input interfaces, the analogue or digital A/V signals (SDI) will be converted into DVB data and
pooled to a standard DVB signal or added to the DVB transport stream being forwarded.
The parameters necessary for the input interfaces and the transport stream parameters have been pre-set at the factory (see section
3.2).
See section 3.3.4 for details of how EMA cascade systems using multiple devices are brought into use and how the transport stream 
can be manipulated from the HTML user interface.
