Target data rate:

To optimize utilization of the bandwidth in your network, you can limit the data

rate for the VideoJet 8008. 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 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). 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 of the P-frame video quality. 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.
