I-frame Distance
This parameter allows you to set the intervals in which the I-
frames will be coded. 0 means auto mode, whereby the video
server inserts I-frames as necessary. An entry of 1 indicates that
I-frames are continuously generated. An entry of 2 indicates
that only every second image is an I-frame, and 3 only every
third image etc.; the frames in between are coded as P-frames.
I-frame Quality
This setting allows you to adjust the image quality of the I-
frames. The basic setting Auto automatically adjusts the quality
to the settings for the P-frame video quality. Alternatively, you
can use the slide control to set a value between 9and51. The
value 9 represents the best image quality with, if necessary, a
lower frame refresh rate depending on the settings for the
maximum data rate. A value of 51 results in a very high refresh
rate and lower image quality.
P-frame Quality
This setting allows you to adjust the maximum image quality of
the P-frames. The basic setting Auto automatically adjusts to
the optimum combination of movement and image definition
(focus). Alternatively, you can use the slide control to set a
value between 9and51. The value 9 represents the best image
quality with, if necessary, a lower frame refresh rate depending
on the settings for the maximum data rate. A value of 51 results
in a very high refresh rate and lower image quality.
