PCoIP Client-Side Image Cache
PCoIP client-side image caching stores image content on the client to avoid retransmission. This feature
reduces bandwidth usage.
The PCoIP image cache captures spatial, as well as temporal, redundancy. For example, when you scroll
down through a PDF document, new content appears from the boom of the window and the oldest content
disappears from the top of the window. All the other content remains constant and moves upward. The
PCoIP image cache is capable of detecting this spatial and temporal redundancy.
Because during scrolling, the display information sent to the client device is primarily a sequence of cache
indices, using the image cache saves a signicant amount of bandwidth. This ecient scrolling has benets
both on the LAN and over the WAN.
n
On the LAN, where bandwidth is relatively unconstrained, using client-side image caching delivers
signicant bandwidth savings.
n
Over the WAN, to stay within the available bandwidth constraints, scrolling performance would be
degraded without client-side caching. Over the WAN, client-side caching saves bandwidth and ensure a
smooth, highly responsive scrolling experience.
With client-side caching, the client stores portions of the display that were previously transmied. The cache
size is one-half of the available RAM. If that amount of RAM is less than 50 MB, the cache size is 50 MB.
Suppress the Cellular Data Warning Message
When Horizon Client detects that you are using a cellular data connection, the Network Usage dialog box
appears to notify you that your remote desktop or application connection might use a substantial portion of
your data plan.
The Network Usage dialog box appears after you connect to a server and try to launch a remote desktop or
application, after you tap a recent desktop or application shortcut, and after you connect to a remote
application and try to launch another application or remote desktop from the Unity Touch sidebar. The
Network Usage dialog box appears only when you launch Horizon Client.
You can suppress the Network Usage dialog box after it appears. You can also set an option to always
suppress the Network Usage dialog box.
Procedure
n
To suppress the Network Usage dialog box after it appears in Horizon Client, tap Never Remind in the
Network Usage dialog box.
n
To set an option to always suppress the Network Usage dialog box, tap  at the boom of the
Horizon Client screen and toggle the Cellular Data Warning option to o.
Internationalization
Both the user interface and the documentation are available in English, Japanese, French, German,
Simplied Chinese, Traditional Chinese, Korean, and Spanish. You can also input characters for these
languages.
