Dell Wyse ThinOS Version 8.5 Hotfix 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 show the image on screen. It should improve user experience especially for HDX3DPro desktops.

Supported environment

Citrix Virtual Apps and Desktops 7.5 or later versions

Supported platforms

All the ThinOS 8.5-based devices support ICA SuperCodec.

Verifying the working status of the ICA connections

• For Wyse 3010 with ThinOS (T10) and Wyse 3020 with ThinOS (T10D)

  ICA SuperCodec is enabled by default when ThinOS resolution is lesser than or equal to 1920 x 1080.

  1. When the feature is working, the following results are displayed:

     ThinOS event log ICA: SuperCodec enabled

     

     Click HDX Monitor > Graphics > Thinwire advanced > Encoder: DeepCompressionV2Encoder for NON-HDX3DPro desktops or DeepCompressionEncoder for HDX3DPro desktops.

     From Citrix Virtual Apps and Desktops 7.11, the Encoder is changed to Deprecated.

     

     

  2. When the feature is disabled, you can view the following results:

     ThinOS event log: System resolution exceeds hardware limitation (1920 x 1080), disable SuperCodec

     

     Click HDX Monitor > Graphics > Thinwire Advanced > Encoder > CompatibilityEncoder; CompatibilityEncoder.

     From Citrix Virtual Apps and Desktops 7.11, the Encoder is changed to Deprecated.

     

• For Wyse 3010 with ThinOS (T10) and Wyse 3020 with ThinOS (T10D):
  • ICA SuperCodec is always enabled without any limitation.
  • ThinOS event log displays ICA: SuperCodec enabled.
