Courtroom Setup for Remote Conferencing
The Liberty Remote Conferencing facility is an optional component of the Liberty Court Recorder.
Courts may use the conferencing facility to have remote users conference with the courtroom over an Internet connection. The Court should review the following courtroom configuration details, prior to scheduling remote conferences.
The diagram below provides an overview of the required setup. The Liberty Virtual Courtroom must be installed at the remote location. The courtroom must have an appropriate mixer and speakers, to allow the remote user to be heard in the courtroom. Other facilities, such as video support may optionally be used.
For conferencing applications, we strongly recommend the following setup:
Echo Cancelling Webcams
A court may use an echo cancelling webcam to integrate the capture of both the video and audio into a single device.
Such devices also incorporate echo cancelling features. These devices can eliminate the worry about positioning the speakers and microphones in the courtroom.
Recorder Application Configuration
The Remote Conferencing options tab in the Recorder options must be completed. The Court must specify:
Optional Video Equipment
The Remote Agent facility allows for the sending of video between the courtroom and the remote parties. If video is required, then cameras and video display monitors must be provided. The recording PC must also include support for dual monitors in Windows. One of the monitors can be a large screen monitor that may be watched by those attending the court.
Courts should be aware, video can be presented between the courtroom and the remote user, but the court may exclude the video from the recording file. As illustrated below, a checkbox in the Recorder configuration options determines if the video data will be saved into the recording file.
Use of the Remote Conferencing facility requires a mixer with at least one available audio output, that may be used by the Liberty Recorder.
Using the Motu 8Pre USB
The Motu 8Pre USB connects to the PC using a standard USB cable.
The Motu has two 1/4 inch plugs on the back labeled "Main Out L - R". These 1/4 audio outputs should be used to output audio from the remote agent into speakers that can be heard in the courtroom. The Main Out "L" is accessed by specifying "Motu-1 Audio ASIO" and Main Out "R" is accessed by specifying "Motu-2 Audio ASIO". You must specify one of these Motu outputs into Primary Output of the Remote Agent tab of the Recorder Options.
Using the Presonus 1818VSL
In the case of the Presonus 1818VSL, the mixer must be configured for each user who will use the
Remote Agent facility.
If this is a new recording PC and the users have not previously logged into the PC to establish their local "Windows Desktop Settings", then the administrator can save both of the configuration files into the system Default user account folders, as below:
If this PC has been used previously, and users have previously establish their local "Windows Desktop Settings", then the administrator must save both of the configuration files into the individual users user account folders, as below:

The biggest challenge when introducing Remote Conference sessions into the courtroom, is to minimize the effects of echo. Echo occurs when the words spoken by the remote user are sent to the courtroom speaker(s) and subseqently captured by the courtroom microphones. Once captured by the courtroom microphones, this audio is then heard by the remote user. It can be disconcerting to the remote user to hear their own voice, with a one-second delay. It can cause significant problems for the remote user to the extent that they cannot focus on what they are saying, or what is being said by others in the courtroom.
To minimize the echo effect, the audio from the remote user must be kept as low as is reasonable in the courtroom. Additionally, instead of one or two speakers that provide audio over the entire courtroom, we suggest the idea of 2 sets of speakers, that localize the audio to specific points in the courtroom. Two sets of speakers would involve four speakers in total. One speaker can be used at the witness box. One speaker can be used at the Justice. And the last two speakers can be used by the opposing lawyers. Be sure to point the speakers and the microphones in the same direction, as shown below.
Your Liberty dealer can provide various speaker arrangements allowing for the localization of the audio in various parts of the courtroom. Regardless of the exact number and location of the speakers, the court must always:
