MDI analysis:
Mode
Manual: The address of the TV channel, whose data stream should
be analysed, must be entered under Multicast IP and Port. The time
span within which the ARGUS will attempt to receive a data stream is
unlimited. For an active analysis, the ARGUS must be set to
"manual“, it will then use the configured multicast IP address and
request the data stream.
Automatic: The ARGUS will search for the data stream with the
highest data rate of one of the TV channels available. You must enter
the time span within which the ARGUS will attempt to receive a data
stream under Scan time. The ARGUS operates in a passive yet
automatic mode, when the unit is in Bridge or router configuration.
Default setting:
Automatic
Scan time
The time span within which the ARGUS will attempt to receive a data
stream.
Range: 1 to 10 seconds
Default:
3 seconds
Multicast IP
The multicast IP of the TV channel whose data stream should be
analyzed.
Default setting:
224.0.0.0
Port
The port number of the TV channel whose data stream should be
analyzed.
Range: 0 to 65535
Default:
0
Use
IP header
Sets whether the IP header be used: yes or no
It is not possible to determine the packet loss (Media Loss Rate) of a
data stream, which does not have a RTP header (UDP based only).
In this case, it is possible to use the IP header to enable the ARGUS
to determine the packet loss, if its ID field has been suitably
maintained.
Default setting:
No
If Use IP Header has been set to “yes”, but the ID
field of the IP header has not been maintained, the
ARGUS cannot correctly determine the packet loss
(Media Loss Rate).
