According to Citrix, users can roam from device to device, authenticating themselves via XenDesktop’s SmartCard support, and access their desktops no matter what the capabilities of the “endpoint device” are. If a thin client doesn’t have the power to run desktops locally, the desktops run remotely and are sent to the user via “screen scraping.”
On the other hand, if the thin client is an x86 device, desktops — constituting images of both a Windows XP operating system and any applications that have been installed into it — can be streamed to it and will run locally, “leveraging distributed processing power.” Citrix doesn’t specify, however, whether the thin clients had to be booted into Windows in the first place, or if Linux-based x86 systems also quality.
Meanwhile, Citrix also touts its HDX (high-definition user experience), a set of technologies that’s said to enhanced multimedia performance on thin clients. The HDX allows users to work with USB devices locally, and tap into a thin client’s 3D hardware, if present. Via “HDX MediaStream” technology, compressed a/v information — including DiVX, a variety of MPEG flavors, WMV, WMA, and MP3 — is sent to a thin client in its native format, and decompressed locally, the company adds.
