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 2-3 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 Horizon 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.

Configuring Scanner Redirection
By using scanner redirection, Horizon 7 users can scan information in their remote desktops and
applications with scanning and imaging devices that are connected locally to their client computers. Scanner
redirection is available in Horizon 6.0.2 and later releases.
Scanner redirection supports standard scanning and imaging devices that are compatible with the TWAIN
and WIA formats.
After you install Horizon Agent with the Scanner Redirection setup option, the feature works on your
remote desktops and applications without further conguration. You do not have to congure scanner-
specic drivers on remote desktops or applications.
You can congure group policy seings to change default values to adapt to particular scanning and
imaging applications or environments. You can also set a policy to disable or enable the feature altogether.
With an ADMX template le, you can install scanner redirection group policy seings in Active Directory or
on individual desktops. See “Conguring Scanner Redirection Group Policy Seings,” on page 35.
When scanning data is redirected to a remote desktop or application, you cannot access the scanning or
imaging device on the local computer. Conversely, when a device is in use on the local computer, you cannot
access it on the remote desktop or application.
System Requirements for Scanner Redirection
To support scanner redirection, your Horizon 7 deployment must meet certain software and hardware
requirements.
Horizon 7 remote
desktop or application
This feature is supported on RDS desktops, RDS applications, and VDI
desktops that are deployed on single-user virtual machines.
You must install View Agent 6.0.2 or later, and select the Scanner Redirection
setup option, on the parent or template virtual machines or RDS hosts.
On Windows Desktop and Windows Server guest operating systems, the
Horizon Agent Scanner Redirection setup option is deselected by default.
