Release Notes

Citrix supports 64–bit Linux operating systems from HDX RTME 2.1. Hence, do not install any optional 32-bit add-ons, as it is now included

in the base image and is enabled by default.

RTME 2.1 Compatibilities and Limitation

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 dierent levels for the information transmitted such as frames per second, image size, and

quality granularity. The receiving devices can choose what to take from the transmission, and optimize 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 Forward Error Correction (FEC), higher quality content is

obtained over lossy connections.

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

Endpoint identication 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 specic location information is included. This information includes street address and the oor

number for oce buildings. Responders are directed to the correct emergency location. For more information,
