Bosch Video Management System
With the image encoding interval you configure the interval at which images are encoded and
transmitted. If 1 is entered, all images are encoded. Entering 4 means that only every fourth
image is encoded, the following three images are skipped - this can be particularly
advantageous with low bandwidths. The lower the bandwidth the higher this value should be
to achieve best-quality video.
Target bit rate [Kbps]:
Move the slider or type the appropriate value.
You can limit the data rate for the encoder to optimize usage of 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 bit rate [Kbps]:
field.
Maximum bit rate [Kbps]:
Move the slider or type the appropriate value.
With the maximum bit rate you configure the maximum transmission speed which cannot be
exceeded.
You set a bit rate limit to be able to reliably determine the appropriate disk space for storage
of the video data.
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 bit
rate [Kbps]: field. If the value entered here is too low, it will automatically be adjusted.
I-Frame Distance
This parameter allows you to set the intervals in which the I-Frames are coded. Click
Automatic, to insert 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 I-Frames in between are coded as P-Frames.
Frame Quality Level
Here you can set a value between 0 and 100 for both the I-Frames and the P-Frames. The
lowest value results in the highest quality and the lowest frame refresh rate. The highest value
results in the highest frame refresh rate and the lowest image quality.
The lower the available transmission bandwidth, the higher adjust the quality level to maintain
high quality of the video.
Note:
You adjust the video quality dependent on the motion and level of detail in the video. If you
check the Automatic check boxes, the optimum relationship between motion and image
definition is automatically adjusted.
VIP X1600 XFM4 Settings
Allows you to configure the following H.264 settings for the VIP X 1600 XFM4 encoder module.
H.264 deblocking filter: Select to improve visual quality and prediction performance by
smoothing the sharp edges.
CABAC: Select to activate high efficient compression. Uses a large amount of processing
power.
