Chapter 7 - Conference Types

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.
