GoQAM Input Pairs
The GoQAM associates the DVB ASI inputs as pairs of clear and encrypted inputs
for Overlay purposes. This means that each DVB ASI input constitutes a dedicated
pair of clear and encrypted streams. Each pair carries a clear digital broadcast stream
on one input and its encrypted form on the other input. For example, ASI IN 1 and
ASI IN 2 carry the clear and encrypted forms of the same digital transport stream,
respectively.
