Dual Video

End points that support Emblaze-VCON’s HD DualStream™ (vPoint HD,

HD5000, HD4000, HD3000 and HD2000) or other dual-video capability can

send video and data streams simultaneously to a multipoint conference

through the VCB. During a conference, end points supporting HD DualStream

can view documents, graphics, and presentations as the main image, while the

video appears as a PIP inset on the screen.

Systems not supporting H.239 display only the shared

data in a single window.
