The Receiver includes a broad set of technologies that provide a high-definition user experience for today's media-rich user environments. These improve the user experience when connecting to hosted applications and desktops.
HDX Mediastream Windows Media Redirection overcomes the need for the high bandwidths required to provide multimedia capture and playback on virtual Windows desktops accessed from Linux user devices. Windows Media Redirection provides a mechanism for playing the media run-time files on the user device rather than on the server, thereby reducing the bandwidth requirements for playing multimedia files.
With client-side fetching, you can also allow the user device to stream media directly from URLs of the form http://, mms://, or rtsp:// rather than streaming the media through a Citrix server. The server is responsible for directing the user device to the media, and for sending control commands (including Play, Pause, Stop, Volume, Seek), but the server does not handle any media data. This feature requires advanced multimedia GStreamer libraries on the device.
Most Linux distributions include GStreamer. Alternatively, you can download GStreamer from http://gstreamer.freedesktop.org.
Note the following about the client-side fetching feature:
HDX MediaStream Flash Redirection enables Adobe Flash content to play locally on user devices, providing users with high definition audio and video playback, without increasing bandwidth requirements.
Enables HDX Mediastream for Flash on the user device. By default, this is set to Ask and users are presented with a dialog box asking them if they want to optimize Flash content when connecting to web pages containing that content.
Enables or disables server-side content fetching for Receiver. By default this is set to Disabled.
Enables or disables HTTP cookie redirection. By default, this is set to Disabled.
Enables or disables client-side caching for web content fetched by Receiver. By default, this is set to Enabled.
Defines the size of the client-side cache, in megabytes (MB). This can be any size between 25 and 250 MB. When the size limit is reached, existing content in the cache is deleted to allow storage of new content. By default, this is set to 100.
HDX RealTime provides a webcam video compression option to improve bandwidth efficiency during video conferencing, ensuring users experience optimal performance when using applications such as GoToMeeting with HD Faces, Skype, or Microsoft Office Communicator.

Receiver supports the display of H.264 graphics, including HDX 3D Pro graphics, that are served by XenDesktop 7. This support uses the deep compression codec feature, which is enabled by default. The feature provides better performance of rich and professional graphics applications on WAN networks compared with the existing JPEG codec.
Follow the instructions in this topic to disable the feature (and process graphics using the JPEG codec instead). You can also disable text tracking while still enabling deep compression codec support. This helps to reduce CPU costs while processing graphics that include complex images but relatively small amounts of text or non-critical text.
