Here’s a straightforward (and hype-free) introduction to HDX. Let me know what you think.

Put very simply, HDX (or High Definition eXperience) is our way to talk about all the elements of the Citrix remote access technology that affect the user’s computing experience. It’s designed to provide a Systematic Framework to talk about the Citrix Delivery Center in a way that focuses upon the user experience. It takes all the elements that might impact on the end-user’s XenApp or XenDesktop experience and provides a straight forward way to talk about them. It also elevates the discussion beyond protocols. Don’t worry, the ICA protocol remains a key part of the Citrix story, but the ability of our solutions to deliver a great user experience is much broader than simply talking about a remoting protocol.

In the following I build the story step by step.

HDX – Broadcast

HDX – Broadcast refers to Citrix capabilities for providing virtual desktops and applications over any network. It provides the underlying transport for many of the other HDX technologies. HDX – Broadcast includes many of the technologies very familiar to ICA experts such as instant mouse click feedback, keystroke latency reduction, multi-level compression, session reliability, and queuing and tossing.

HDX – Plug and Play

HDX – Plug and Play refers to current and future capabilities to provide connectivity for local devices and applications in a virtualized environment, including USB, multi-monitor, printers, and peripherals. HDX – Plug and Play includes technologies such as multi-monitor support, smart card support, special folder redirection, universal printing, file-type association, and USB support.

HDX – 3D

HDX – 3D refers to Citrix current and future capabilities in remoting high end graphics. It rests upon and extends our HDX – Broadcast capabilities. HDX – 3D includes technologies like image acceleration and progressive display for graphically intensive images. Soon it will include a range of new 3D acceleration technologies from Project Apollo.

HDX – MediaStream

HDX – MediaStream refers to Citrix current and future capabilities for multimedia such as sound and video. It also rests upon and extends our HDX – Broadcast capabilities. HDX MediaStream includes technologies for streaming media files to the client device for playing via local codecs with seamless embedding into the remote session.

HDX – RealTime

HDX – RealTime refers to Citrix current and future capabilities for real time communications such as voice and web cameras. It rests upon and extends our HDX – Broadcast capabilities. HDX – RealTime is today a work in progress with several technologies ranging from EasyCall to our bi-directional audio functionality. The near future will see dramatic enhancements to our ability to support real-time communication via both voice and video on the remote client.

HDX – IntelliCache

HDX – IntelliCache refers to Citrix current and future capabilities to locally cache bandwidth intensive data and graphics and locally stage streamed applications. Here we use Branch Repeater to illustrate IntelliCache as it caches common application display data for multiple users locally to the branch office, eliminating redundant transfer of commonly used application objects.

HDX – Adaptive Orchestration

HDX – Adaptive Orchestration refers to current and future capabilities that enable seamless interaction between the HDX Technology categories. A central concept is that all these components work adaptively to tune the unified HDX offering for the best possible user experience.

HDX Technology Futures

Citrix has a broad range of technologies under R&D that will continue to build the HDX story. (Some of you will have heard of project Apollo … hint – check out Derek Thorsland’s posts)
