The Continuum DVP XDQA system is provided with two Gigabit Ethernet ports, 
which receive up to 512 IP-encapsulated MPEG2 Single Program Streams (SPTS) 

After de-encapsulating and buffering, the switch engine routes a number of input 
program streams to the sixteen QAM modulators and creates the necessary PSI 
tables (PAT and PMT). 

The Dual QAM Cards buffer, re-stamp and route the signals to one of the two QAM 
modulators on the Dual QAM Cards.
