5.5 Experiencing an H.239 Dual-Stream Conference

During an H.239 dual-stream conference, two independent video stream channels, that is, the
video and the presentation, can be transmitted; furthermore, two channels of video from the local
site can be transmitted or two channels of video from a remote site can be received at the same
time.

5.5.1 Designing the Video and Presentation Capabilities

The dual-stream mode can be used in point-to-point calls or in multipoint conferences.
The dual-stream capabilities of the HUAWEI 9000 are listed as follows:

The desktop contents of a computer can be PowerPoint files, video clips, and other contents that
can be displayed on the desktop. The resolutions supported in Super eXtended Graphics Array
(SXGA) interface mode are 800 × 600 pixels, 1024 × 769 pixels, 1280 × 720 pixels, and 1280
× 1024 pixels.
Before initiating a dual-stream conference, set the video and H.239 video parameters as
described in section
dynamically associated with the H.239 parameters, and the video protocols are dynamically
associated with the video resolution, frame rate, and conference bandwidth; therefore, you need
to set these parameters based on the available options on the screen. For details about the
conference parameters, see
