Dell Wyse ThinLinux 1.0.3 Administrator’s Guide

Starting from HDX RTME 2.1, Citrix supports 64–bit Linux operating systems. Hence there is no need to install any optional 32-bit add-ons, as it is now packaged along with base image. This feature is enabled by default.

Features of RTME 2.1

The following are the features of RTME (Real Time Media Engine):

• Improved audio and video quality:

  • Support for H.264 Scalable Video Coding (SVC): SVC handles the transmission of video over varied network and device environments. The sending system includes different levels for the information transmitted such as frames per second, image size, and quality granularity. The receiving device selects the required information from the transmission and optimizes the experience on those devices.
  • SILK audio codec: Delivers higher audio quality across a wide range of network environments, including the public Internet and mobile networks.
  • Improved audio and video quality over lossy connections: By enabling the forward error correction (FEC), we provide higher-quality content over lossy connections.

• Support for 64-bit architecture: Linux 64-bit operating systems are now supported for the Real-Time Media Engine. 

• Endpoint identification for location services:

  • Enhanced 9-1-1 (E9-1-1) and E999, E100, and so on: An international emergency dispatch feature that associates a 911 (or an international emergency) call with a specific location information. This information includes street address and the floor number for office buildings. Responders are directed to the correct emergency location. For more information, see Technet.microsoft.com/en-us/library/dn951423.aspx.
  • Support for Quality of Experience (QoE) reporting: Use Quality of Experience data to keep a record of the quality of your users' audio and video calls, including: 

    • Number of network packets lost

    • Background noise

    • Amount of jitter (differences in packet delay)

    • Names of devices used for a call

    • Names of devices used for a call

    • ICE Warning flags

    • Endpoint statistics

  • Skype for Business users can communicate with Skype users: Skype for Business users can communicate with Skype users.
  • Flexible upgrades: Simplified backward compatibility for upgrading from version 2.0.x 
  • Fallback mode control: You can disable fallback mode or limit fallback control to server-side media processing for audio only (no video), which reduces CPU impact.
  • Administrator control of system notification balloons: You can enable or disable the system notification balloons the Optimization Pack displays.
  • The Real-Time Optimization Pack About page: The following information can be viewed in the About page:

    • Status of Real-Time Optimization Pack

    • Skype for Business version number

    • Operating systems on which the Real-Time Connector and Real-Time Media Engine are running

    • NOTE: In the fallback mode, the version and operating system fields for Real-Time Connector and Real-Time Media Engine display the same values because the Real-Time Optimization Pack uses the Real-Time Media Engine within the Real-Time connector.
  • Localization: Real-Time Media Engine installers for Linux 64-bit OS are localized and available in German, French, Spanish, Japanese, and Simplified Chinese.
  • Skype for Business 2016: The current Skype for Business 2016 client does not support Real-Time Optimization pack.
