INSTRUCTIONAL AREAS: VIDEO TELECONFERENCING VI Room Type
CLASSROOM
Varies Sq. Ft.
DESCRIPTION
Video Teleconferencing Classroom (VTC)
INTENDED USE
This room will support use of interactive video for teaching and learning. Room systems will produce origination of audio and video for two-way communication. Control systems will be sufficiently user friendly to enable operation by the instructor or an assistant. Professional staff will not be required to operate the systems. The classroom system will capture live video of all participants in the room, as well as transmit video sources such as document camera, scan converted computer video, VCR playback and record, and cable TV. Microphone pickup will allow participation by all people in the classroom. Local audio will have a mute function.
Display systems will allow users to see both outgoing video signals, local display from document camera, etc., and video signals from remote sites. Multi-point sessions will display voice activated signals from remote sites.
Network connections will be both pre-programmed through central scheduling systems and manually managed from the room. Room systems will be permanently installed, and all user equipment will be available with minimum setup. Room setup can be accomplished in less than 15 minutes, with the work being performed by non-professional staff.
