Dell Wyse ThinOS Version 8.6.1 Administrator's Guide

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

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.
