For complex images or frequent changes of image content due to frequent

movements, this limit can temporarily be exceeded as far as the value you enter

in the Max. data rate: field.

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 can result in the skipping

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 video 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 relationship between movement and image definition (focus).

Selecting Manual allows you to set a value between 4 and 31 on a slide bar. The

value 4 represents the best 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 video 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 a slide

bar. The value 4 represents the best 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 determines the number of inter-coded frames between two

I-frames.

Encoding interval:

The figure selected here determines the interval at which images are encoded

and transmitted. For example, entering 4 means that only every fourth image is

encoded, the following three images are skipped – this can be particularly

advantageous with low bandwidths.
