•
TS Packet Per Frame:
This field enables the user to enter the number of MPEG packets to be
encapsulated per IP packet. The range of MPEG packets per IP packet is from 1 to 7. Long-
length packets are undesirable due to the excessive impact from losing each IP packet. Short
packets cause a high overhead so a value chosen will be a compromise between these two
factors.
•
TS Packets Size:
This field enables the user to select the size of the TS packet. The size
options include
Auto, 204 bytes
or
188 bytes
.
•
FEC (Forward Error Correction) Mode:
This field enables the user to enter the FEC mode to
be used. It will be either FEC 1D (1 Dimensional) or FEC 2D (2 Dimensional).
•
FEC Column:
This field enables the user to enter the number of packets per column to be
associated with an FEC packet.
•
FEC Row:
This field enables the user to enter the number of packets per row to be associated
with an FEC packet.
•
FEC Offset (Annex A):
Use this drop down menu to enable the use of a non-block aligned FEC
arrangement, which is an alternative method of generating the FEC packets. For more
information on the FEC offset refer to the Pro-MPEG Code of Practice #3 release 2, Annex A.

MONITOR TAB
The Monitor page displays the status of the Ethernet Data ports and the ASI input ports. The
Output
IP Stream Monitor
section displays the port’s mode of operation in the
Status
field and the
Total Bit
rate
that is being output.
The
ASI Input Monitor
section displays the status of the ASI inputs. The status will not change unless
a valid ASI feed is detected (you may be required to refresh the status or select auto-refresh to view
the change). Using the
auto refresh
button can aid troubleshooting of connectivity issues, however, it
will prevent any configuration changes. The ASI monitoring fields can be reset at any time by clicking
on the “
Clear ASI 1 Stats
” button.
