Max. data rate:
This maximum data rate is not exceeded under any circumstances. Depending
on the video quality settings for the I- and P-frames, this fact can result in skip-
ping of individual images.
The value entered here should be at least 10% higher than the value entered in
the Target data rate field.
P-frame quality:
This setting allows you to adjust the image quality of the P-frames depending on
the movement within the image. The Auto option automatically adjusts to the
optimum combination of movement and image definition (focus). Selecting Man-
ual allows you to set a value between 4 and 31 on the slide control. The value 4
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 31 results in a
very high refresh rate and lower image quality.
I-frame quality:
This setting allows you to adjust the image quality of the I-frames. The Auto
option automatically adjusts the quality to the settings for the P-frame video
quality. Selecting Manual allows you to set a value between 4 and 31 on the
slide control. The value 4 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 31 results in a very high refresh rate and lower image quality.
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 when
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.
