Mix Sending
Content sharing allows users to share content with other conference participants during a call.
When a PC is connected to the PC port on the VC400/VC120 Codec, the display device can
display both the camera video and the shared content. The content sharing feature is very useful
in the conference scenario in which content sharing is needed (e.g., a slide or a flash).
During a conference call, the far site may not support receiving shared content. In this case, you
can enable mix sending feature on the system. Mix sending feature allows the sender to
compound multiple video streams (local image+shared content) to one video stream, and then
send it to the far site.
The mix sending parameter on the system is described below.
