32 IP-R EACH USER M ANUALInternet Flow ControlMany public WAN links are by their very nature unpredictable. Packets sent over the public Internet do notnecessarily arrive at their destination in the order they were sent. When using IP-Reach over anunpredictable public WAN (particularly in international scenarios), the Internet Flow Control toggleensures that packets transmitted by IP-Reach are received and reconstructed by RRC in the correct order.SmoothingThe video smoothing level instructs IP-Reach to what degree color gradation shifts are relevant fortransmission. Video pixels that stray from the majority color are assigned approximated color values toreduce bandwidth used and video noise transmitted. Overly high smoothing levels can result in colorinaccuracies; whereas lower smoothing levels require greater bandwidth and processing power.Video SettingsVideo Settings N/A Opens the Video Settings dialog box to manually adjust videoconversion parameters.To access the Video Settings dialog box, either select Video → Video Settings from the RRC Menu Bar,or click on the [Connection Properties] button in the RRC Toolbar.Most of the settings in this dialog box can be refreshed by performing Color Calibration, as described in thenext section, or by manually forcing IP-Reach to auto-detect the video settings (on the RRC Menu Bar,select Video → Auto-sense Video Settings). However, it is useful for power users to understand themeanings and ramifications of each setting.Noise FilterThe video output of graphics cards are transmitted in analog form, and are susceptible to electrical andinterference noise. IP-Reach's advanced circuitry can filter out these small, false, and unintended signalvariations, thereby optimizing picture quality and bandwidth consumed.Higher: Noise Filter settings instruct IP-Reach to transmit a variant pixel of video only if a large colorvariation exists in comparison to its neighbors. However, setting the threshold too high can result in theunintentional filtering of desired screen changes.Lower: Noise Filter settings instruct IP-Reach to transmit most pixel changes. Setting this threshold too lowresults in higher bandwidth utilization.Note: Lower Noise Filter settings (approximately 1 to 4) are recommended. Although higher settings willstop the needless transmission of false color variations, true and intentional small changes to a videoimage may not be transmitted.
