Polycom Visual Concert PC

Polycom Visual Concert enables the sending of two separate video streams: video and data. Typically, the video stream is transmitted in the standard H.263 resolution in high frame rate while the data video stream is transmitted in a higher resolution but lower frame rate.

Polycom Visual Concert can be enabled for Video Switching conferences for both H.320 and H.323 participants.

The Visual Concert feature is available with Polycom's ViewStation PC endpoints. In order to activate this option, the Polycom Visual Concert PC application must be installed on the same computer deployed as the data source. This computer is connected via the LAN to the ViewStation endpoint that will broadcast the data to all conference participants. The data stream may be received by both ViewStation and View Station FX endpoints.
