7 Imaging Considerations

Configuration of imaging parameters has a large
impact on the user experience and bandwidth
usage in PCoIP Systems. This section reviews
some imaging configuration considerations.
Imaging Configuration
Image webpage allows configuration of imaging
parameters to balance:
• Preference to have lower quality images at
higher frame rate, vs.
• Preference to have higher quality images at a
lower frame rate
Figure 14: Image Webpage
The Image webpage has two fields:
Minimum Image Quality:
• Allows balancing between image quality and
frame rate for limited bandwidth scenarios
• Selecting towards Reduced allows higher
frame-rates (and lower quality display) when
network bandwidth is constrained
• Selecting towards Perception-Free allows
higher image quality (and lower frame rates)
when network-bandwidth is constrained
• When network bandwidth is not constrained,
PCoIP System will maintain maximum quality
regardless of setting
• Must be set less than or equal to Maximum
Initial Image Quality

• Changes the network bandwidth peaks
required by a PCoIP Session by limiting initial
quality on the changed regions of the image
• Selecting towards Reduced will reduce the
image quality of content changes and
decrease peak bandwidth requirements
• Selecting towards Perception-Free will
increase the image quality of content changes
and increase peak bandwidth requirements
• Unchanged regions of image will progressively
build to lossless state regardless of setting
• Maximum Initial Image Quality must be set
greater than or equal to Minimum Image
Quality
• It is recommended to set Maximum Initial
Image Quality to 90 or lower to best utilize the
available network bandwidth
