Dell Wyse ThinOS Version 9.0 Administrator’s Guide

Citrix SuperCodec

Citrix SuperCodec is a H.264 decoder integrated on the ThinOS client side. The server encodes the session image into the H.264 stream and sends it to the client side. The client decodes the H.264 stream by SuperCodec and display the image on the screen. This feature improves the user experience, especially for HDX 3D Pro desktops.

Citrix SuperCodec is supported in Citrix Virtual Apps and Desktops (XenApp and XenDesktop) version 7.5 or later versions.

In Citrix Virtual Apps and Desktops version 7.9 and later, the default setting for Use video codec for compression is Use when preferred. For best performance on ThinOS device, it is recommended that you set the Use video codec for compression policy to For the entire screen. You can set the policy to Do not use video codec. This policy setting allows ThinOS to use ThinWire Plus that saves bandwidth and reduces the CPU overhead. You can also set the policy to For actively changing regions. This policy setting allows ThinOS to use Selective H.264.

• Fullscreen H.264—Equivalent to the For the entire screen option
• Selective H.264—Equivalent to the For actively changing regions
