Setting Description
Disable RTAV When you enable this setting, the Real-Time Audio-Video feature is disabled.
When this setting is not configured or disabled, Real-Time Audio-Video is enabled.
This setting is located in the View RTAV Configuration folder.
Max frames per
second
Determines the maximum rate per second at which the webcam can capture frames. You can use this
setting to limit the webcam frame rate in low-bandwidth network environments.
The minimum value is one frame per second. The maximum value is 25 frames per second.
When this setting is not configured or disabled, no maximum frame rate is set. Real-Time Audio-
Video uses the frame rate that is selected for the webcam on the client system.
By default, client webcams have a frame rate of 15 frames per second. If no setting is configured on the
client system and the Max frames per second setting is not configured or disabled, the webcam
captures 15 frames per second.
This setting is located in the View RTAV Configuration > View RTAV Webcam Settings folder.
Resolution -
Max image
width in pixels
Determines the maximum width, in pixels, of image frames that are captured by the webcam. By
setting a low maximum image width, you can lower the resolution of captured frames, which can
improve the imaging experience in low-bandwidth network environments.
When this setting is not configured or disabled, a maximum image width is not set. RTAV uses the
image width that is set on the client system. The default width of a webcam image on a client system is
320 pixels.
The maximum limit for any webcam image is 1920x1080 pixels. If you configure this setting with a
value that is higher than 1920 pixels, the effective maximum image width is 1920 pixels.
This setting is located in the View RTAV Configuration > View RTAV Webcam Settings folder.
Resolution -
Max image
height in pixels
Determines the maximum height, in pixels, of image frames that are captured by the webcam. By
setting a low maximum image height, you can lower the resolution of captured frames, which can
improve the imaging experience in low-bandwidth network environments.
When this setting is not configured or disabled, a maximum image height is not set. RTAV uses the
image height that is set on the client system. The default height of a webcam image on a client system
is 240 pixels.
The maximum limit for any webcam image is 1920x1080 pixels. If you configure this setting with a
value that is higher than 1080 pixels, the effective maximum image height is 1080 pixels.
This setting is located in the View RTAV Configuration > View RTAV Webcam Settings folder.
Resolution -
Default image
resolution
width in pixels
Determines the default resolution width, in pixels, of image frames that are captured by the webcam.
This setting is used when no resolution value is defined by the user.
When this setting is not configured or disabled, the default image width is 320 pixels.
The value that is configured by this policy setting takes effect only if both View Agent 6.0 or later and
Horizon Client 3.0 or later are used. For older versions of View Agent and Horizon Client, this policy
setting has no effect, and the default image width is 320 pixels.
This setting is located in the View RTAV Configuration > View RTAV Webcam Settings folder.
Resolution -
Default image
resolution
height in pixels
Determines the default resolution height, in pixels, of image frames that are captured by the webcam.
This setting is used when no resolution value is defined by the user.
When this setting is not configured or disabled, the default image height is 240 pixels.
The value that is configured by this policy setting takes effect only if both View Agent 6.0 or later and
Horizon Client 3.0 or later are used. For older versions of View Agent and Horizon Client, this policy
setting has no effect, and the default image height is 240 pixels.
This setting is located in the View RTAV Configuration > View RTAV Webcam Settings folder.
Real-Time Audio-Video Bandwidth
Real-Time Audio-Video bandwidth varies according to the webcam's image resolution and frame rate, and
the image and audio data being captured.
The sample tests shown in Table 13-2 measure the bandwidth that Real-Time Audio-Video uses in a View
environment with standard webcam and audio input devices. The tests measure the bandwidth to send both
video and audio data from Horizon Client to View Agent. The total bandwidth that is required to run a
desktop session from Horizon Client might be higher than these numbers. In these tests, the webcam
captures images at 15 frames per second for each image resolution.
