Duo Video
Duo Video supports two simultaneous ISDN conferences - a regular video
conference, and content conference. A Tandberg DuoVideo capable endpoint
accommodates two calls, one for the participant conference and the second
for a demo/presentation on a second monitor. Using Duo Video, participants
at the remote site can simultaneously watch the presenter on one screen and
view a live presentation on an adjoining screen. Both conferences are
independent one from the other, and there is no indication on the system that
the DuoVideo conference is in any way related to the other.
Duo Video is available with both Video Switching and Transcoding
conferences. The first conference operates as a normal conference in a Video
Switching (VSW), Continuous Presence (CP), or in a Transcoding mode. The
second is also a standard conference but has distinct attributes: the conference
operates in a DuoVideo mode.
The speaker of the second conference is decided by force status. The
determination of who is to be speaker of the first conference has no influence
of who is to be the speaker of the DuoVideo conference. The speaker of the
'DuoVideo' conference is the presenter of the lecture/presentation.
With DuoVideo conferences, Tandberg endpoints are required to have a dual
monitor connected and also need access to two phone lines.
