Profile name
You can enter a new name for the profile here. The name is then displayed in the list of
available profiles in the Profile name field.
Target data rate
You can limit the data rate for the AutoDome 700 Series to optimize utilization of the
bandwidth in your network. The target data rate should be set according to the desired
picture quality for typical scenes with no excessive motion.
For complex images or frequent changes of image content due to frequent movements, this
limit can be temporarily exceeded up to the value you enter in the Maximum data rate field.
Maximum 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 individual images being skipped.
The value entered here must be at least 10% higher than the value entered in the Target data
rate field. If the value entered here is too low, it will automatically be adjusted.
Video resolution
Here you can select the desired resolution for the video image. The following resolutions are
available for standard definition settings only:
– CIF
352 × 288/240 pixels
– 4CIF/D1
704 × 576/480 pixels
Encoding Interval
The figure selected here determines the interval at which images are encoded and
transmitted. The image rate in ips (images per second) is displayed next to the text field.
Use the slide bar to select a frame rate from 30.00 ips to 1 ips.
Expert Settings
Use the expert settings to adapt the I-frame quality and the P-frame quality to specific
requirements, if necessary. The setting is based on the H.264 quantization parameter (QP).
GOP Structure
Select the structure you require for the Group of Pictures here. Depending on whether you
place greater priority on having the lowest possible delay (IP frames only) or using as little
bandwidth possible, you can choose between IP, IBP, and IBBP.
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.
