Release NotesPolycom PVX Version 8.0.16Supported Audio Devices and WebcamsPolycom PVX software is tested extensively with a wide range of audio devicesand webcams. For a list of compatible devices and for important informationabout factors you should consider when selecting your audio and video devices,refer to the Selecting Audio and Video Devices for Use with Polycom PVX document,available athttp://www.polycom.com/common/pw item show doc/1,1276,4556,00.pdf.SoundStation2 and SoundStation2WTo make calls with PVX using the Polycom SoundStation2 orSoundStation2W , you need the Computer Calling Kit. For more informationabout this kit, refer to the Selecting Audio and Video Devices for Use with PolycomPVX document, available athttp://www.polycom.com/common/pw item show doc/1,1276,4556,00.pdf.System PerformancePeople Content sharing requires computer processing and, therefore, demandsa higher performance processor. Systems with a 1.2 GHz Pentium 4 or later cansupport People Content. Content sharing will benefit from additional CPUspeed.For systems with a webcam, all of the processing is done on the computer. Thereis a wide range of computer performance levels. To optimize the videoexperience on each system, a CPU resource manager within the Polycom PVXsoftware gauges the system performance and adjusts the media featuresaccordingly.You can also adjust the way Polycom PVX allocates system resources betweenPVX and other applications. To do this, on the Setup General page, clickPerformance. Choose one of these performance settings:SettingDescriptionBalancedGood video without too great an impact on generalapplication performance.Other ApplicationsMore processing power for running critical applicationswhile reducing the processing allocated to people videoand audio.Polycom PVXGreat audio and video while reducing theresponsiveness of other applications.7

Release NotesPolycom PVX Version 8.0.16Factors Affecting VideoThe video format in a call depends on many factors — both on the near-sitesystem and on the far-site system.Some of the other factors that can affect the video format include: System processor and speed PVX settings under Setup General Performance PVX settings under Setup Video Gatekeeper configuration under Setup H.323 Audio format Presence of content video (send or receive) Camera typeCamera Driver LoadThe For the camera you have selected, specify the camera driver’s load on thesystem setting on the Setup Video Advanced page allows you to configurePVX properly, especially if you need to compensate for a higher CPU load fromthe camera driver. This setting enables you to lower the estimated CPU power bya fixed amount so you can enhance the quality of your PVX video.The original video capture driver load for PVX is approximately 150 MHz worthof CPU resources. Therefore, on a 1.5 GHz computer, the video capture driverwill use 10% of the CPU (you can check this using the Task Manager). On a fastercomputer, the load will be less, such as 5% on a 3.0 GHz system.In the For the camera you have selected, specify the camera driver’s load on thesystem field on the Setup Video Advanced page:If you select.Subtract this amount from your actual CPUspeed.LowNoneMedium200 MHzHigh600 MHz8
