PCoIP Technology User Guide (Vol I) 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 TER0806003 Issue 1 • 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 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 Maximum Initial Image Quality: © 2008 Teradici Corporation Page 17 of 25
