IP Port
UDP port of the video stream. Similar to the
IP Address
, this must be the
destination port in the UDP packet header. If you selected a channel from the
channel guide, this field is automatically populated.
Optionally, you can select
As IP Add
from the drop-down list which indicates to
ignore the port and use the IP address exclusively for identifying video stream
packets. In the case of unicast streams where packets are addressed to a
network device such as an STB, it can be more difficult to determine the UDP
port than the IP address of that device. Therefore, this option allows traffic
analysis based on IP address alone. While the STB may be receiving some data
that is not part of the video stream, it is likely that most traffic will be video data
that qualifies for analysis.
Duration
Duration of the test in seconds, or
Continuous
to run the test until manually
stopped.
Interval
Interval at which to report a full set of current measurement results, applicable to
continuous tests only.
Encapsulation
Method
Encapsulation type of the stream under test.

IGMP Version
Version of IGMP to use for multicast join/leave requests. This must reflect an
IGMP type in use on the network where the request is made.
Options include:
•
1
- IGMP version 1
•
2
- IGMP version 2
•
3
- IGMP version 3
•
D
- Dynamic. The unit attempts to monitor existing IGMP traffic on the network
to determine the type in use.
Codec
Video codec used for the stream under test.
•

•
MPEG4
•
H264
