Video Parameter Description
When None is selected, it indicates dual streams are not
enabled.
Note:
If this setting is H.264, when an endpoint that only
supports H.263 protocol joins in the conference, an H.264
endpoint that originally sent dual streams will terminate
sending dual streams and resend them using the H.263
protocol.
H.239 Setting
The H.239 protocol is used to send dual streams. You can
select three kinds of video quality as needed:
Graphics: for standard video display
Hi-res Graphics: for high-quality video detail display.
Broader bandwidth is required.
Live Video: for full-motion of dynamic video display. The
broadest bandwidth is required.
The RMX 1000 supports a maximum of 20 H.323 video connections and 20 H.323
audio connections. Therefore, the number of endpoint connections supported by the
device in the actual conference depends on the video definition.
Video Settings
To set the conference video layout, click the Video Settings tab on the New
Profile interface.
