Detailed Description
The HallVision system can receive video and audio inputs from a number of inputs. These inputs can be
from the Podium, Attorney #1, or Attorney #2. Any audio input the HallVision system receives will be
output on one audio out line. This single audio out line will be connected to the courtroom’s sound
system. The Video Conferencing system’s video output is available for selection at the podium.
There are 2 touch screens in the HallVision system. 1 touch screen is mounted in the Podium and the
other is in the Witness stand.
An integrated Video Marking System allows the touch screens to be used for drawing on top of any
image being shown.
Both touch screens can superimpose finger drawings over any video signal including: VCR, Document
Camera, Podium notebook, either Attorney notebook, and Video Conferencing.
The touch screen that controls the drawing, on top of the video signal, is the first touch screen that is
touched. This becomes the active touch screen. Until the active touch screen is not being touched, the
other touch screen cannot superimpose anything on top of the video signal. The instant the active touch
screen is no longer being touched; the other touch screen can begin drawing on the video signal and
will then become the active touch screen automatically.

corresponding LED lights up on the other keypad.
Control of the HallVision system begins with the two HallVision keypads. Keys A, B, and C select the
