Conference Profiles
A conference profile is used to pre-define the basic parameters for conference
scheduling, such as the bandwidth, encryption, and video quality. All
conferences will be created on the basis of conference profiles. By saving
conference profiles on the RMX 1000, users can conveniently and rapidly
schedule new conferences without performing repeated configurations. The
following parameters generally decide the video conference quality.
• Bit Rate – The transmission rate of the audio and video streams. The
higher this value is, the better the displayed video quality.
• Video Protocol, Video Format, and Frame Rate – These parameters
define the quality of the video picture. When an endpoint is connected to
the conference, it will select a video capability based on the video
parameters set for the conference. For example, if the video protocol for
the conference is H.264, an endpoint that supports the H.264 protocol
will select H.264 for video coding when it connects to this conference.
The following features are commonly used to define a conference:
• H.239 Dual-stream – An H. 239 compliant endpoint can simultaneously
send and receive two channels of conference video streams: dynamic
conference video and PC screen contents.
• Encryption – The system provides AES 128-based multimedia
encryption to strengthen conference security.
To set a conference profile, click Conference Profiles in the RMX
Management pane. The list pane shows the profiles saved on the current
device and their summaries.
