Polycom Visual Concert FX
The Visual Concert FX (VCFX) feature enables you to view simultaneous
live video and content (data) presentation using high resolution graphics. It is
available with ViewStation FX endpoints. VCFX transmits the video stream
in H.263 format and in a high frame rate (CIF 30 FPS). The data video stream
is transmitted in a higher resolution SXGA (1280 x 1024 pixels) and lower
frame rate (CIF 15 FPS).
Figure 7-6: VCFX Configuration
In a conference with Visual Concert FX settings, the presentation can be
viewed if a Polycom Visual Concert FX box is connected between the
ViewStation broadcasting the presentation and the PC used for the data
source. In case a single video monitor is used for the presentation, the monitor
displays content and broadcasts video.
In a conference using Visual Concert PC settings the ViewStation FX
endpoints uses a resolution of 4 CIF (704 x 480 NTSC, 704 x 576 PAL).
When a ViewStation endpoint without SXGA capabilities enters the
conference, the endpoint connections as Secondary (i.e. Audio Only).
• ViewStation PC endpoints connecting to a conference set to Polycom Visual
Concert FX, connect as Secondary (audio only, without video).
• Supported in only Video Switching Conferences.
• In the MGC WebCommander and MGC Manager applications you define the
properties of the video conference. The properties of the data transmission
are defined internally and cannot be modified from the WebCommander
application.
