ICA SuperCodec
ICA SuperCodec is a H.264 decoder integrated on ThinOS ICA client side. Server encodes the session image into H.264 stream and sends
it to client side. Client decodes the H.264 stream by SuperCodec and display the image on screen. This feature improves user experience
especially for HDX 3D Pro desktops.
Supported Environment
Citrix Virtual Apps and Desktops (formerly XenDesktop) and Citrix Virtual Apps (formerly XenApp) version 7.5 or later versions
Prerequisities
In Citrix Virtual Apps and Desktops (formerly XenDesktop) and Citrix Virtual Apps (formerly XenApp) version 7.9 and later, the default
setting for
Use video codec for compression is Use when preferred. For best performance on ThinOS device, Dell recommends that
you set the
Use video codec for compression policy to For the entire screen. Alternatively, you can also set the policy to Do not use
video codec. This allows ThinOS to use ThinWire Plus that saves bandwidth and reduces CPU overhead.
• ThinWire Plus—Equivalent to Do not use video codec option
• Fullscreen H.264—Equivalent to For the entire screen option
• Selective H.264—Equivalent to For actively changing regions
Verifying the working status of the ICA connections—ICA SuperCodec is always enabled without any limitation. The following
ThinOS event log is displayed:
ICA: SuperCodec enabled
NOTE: For ICA connections, there is no INI parameter.
If you set the Use video codec for compression policy to Do not use video codec, ICA SuperCodec is disabled, and
ThinOS does not print any log.
Anonymous logon
Anonymous logon feature enables the users to log into the StoreFront server configured with unauthenticated store without Active
Directory (AD) user credentials. It allows unauthenticated users to access the applications instead of AD accounts.
NOTE:
Anonymous logon is not supported with legacy mode of StoreFront server.
Configure the Citrix UPD printer
Use of Citrix Universal Printer Driver (Citrix UPD) ensures that all printers connected to a client can also be used from a virtual desktop or
application session without integrating a new printer driver in the data center. Citrix UPD is the base of Citrix Universal Printer. It is an
auto-created printer object that uses the Citrix UPD and is not tied to any specific printer defined on the client.
To configure the Citrix UPD usage on ThinOS:
1. Connect a printer to ThinOS client.
2. From the desktop menu, click System Setup, and then click Printer.
The Printer Setup dialog box is displayed.
3. Enter the name of the printer in the Printer Name box.
4. Enter any string of the Printer identification in the Printer Identification box.
5. Select the type of the printer class from the drop-down list, select the check box to enable the printer device and then click OK.
6. Start a Citrix Virtual Apps and Desktops (formerly Citrix XenDesktop) or Citrix Virtual Apps (formerly Citrix XenApp) application
connection.
7. Open the Devices and Printers in the desktop or application, notice the printer is mapped as UPD printer by default. You can use the
HP-LaserJet-P2035 [UPD:PCL5c] to perform the print job.
Citrix UPD configuration on server
a. To enable the printer policy, use the following guidelines:
1. To enable the printer policy in Citrix Virtual Apps 6.5– Go to the DDC Server, click Start > Citrix AppCenter .
2. Click Citrix Resources > XenApp > Policies > User > Settings > Printing > Client Printers and enable the Auto-create
generic universal printer.
