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.
