GOP Type Video coder group of pictures (GOP) structure, representing the frame sequence
in use on the stream with respect to I, P, and B frames. This value is used only as
a default if the actual frame types and GOP structure cannot be dynamically
detected from the stream.
Options include:
• A - I-frames only, for example:
III…I
• B - One I-frame followed by P-frames, for example:
IPPP...PIPPP...
• C - One I-frame followed by P- and B-frames with two B-frames between each
pair of anchor frames, for example:
IBBPBBP...BBIBBP...
• D - All P-frames, for example:
PPPP...P
• E - One I-frame followed by P- and B-frames with one B-frame between each
pair of anchor pictures, for example:
IBPBP...BIBP...
For more information about MPEG pictures, see About IP multicast on
page 5-35.
GOP Length Number of frames in a group of pictures (GOP) on the stream, related to the
GOP type. This is essentially the I-frame update interval; that is, the number of
frames from one I-frame to the next. This value is used only as a default if the
actual frame types and GOP structure cannot be dynamically detected from the
stream.
Range:
1 - 100
Loss Sensitivity This defines how much the quality assessment should be sensitive towards
packet loss and discards. A higher value indicates the video stream is more
sensitive to packet loss/discard. When set higher, the calculation model will
respond more rapidly to packet loss on the network under test, and packet loss
will have a greater impact on the calculated score. If set lower, the results will be
less affected by packet loss. This setting makes the analysis tunable for different
varieties of encoders and various network environment conditions.
