Courtroom Setup for Hybrid Hearings
with the Virtual Courtroom

The Liberty Virtual Courtroom facility is an optional component of the Liberty Court Recorder.
Courts may purchase a subscription for this component from their Liberty dealer.

A court subscribing to this service can create temporary links and access codes to provide restricted courtroom access for remote participants connecting to the courtroom using the Internet.

Courtroom Setup

Courts must review the following courtroom configuration details, prior to scheduling remote hearings.

The diagram below provides an overview of the required setup. The courtroom must have an voice uplift, commonly referred to as a DSP, and courtroom speakers to allow remote participants to be heard in the courtroom. The DSP must send the audio from the courtroom microphones to the recording computer and it must have echo cancelling features to eliminate echo and feedback. Courtroom cameras are used as required to send video to the remote participants.

Mandatory Setup

For virtual courtroom operations, we recommend the following setup:

  • A recording computer with at least an Intel i7 processor of 3.4Ghz or faster and 16GB of internal memory.
  • An Internet connection with a speed of at least 10Gbps both up and down.
  • The recording computer must have a second video output port, preferably HDMI, that connects to a large screen monitor allowing persons in the courtroom to see the remote participants.
  • An available port on the firewall where the Recorder can initiate UDP traffic from the courtroom. The default UDP port used is Port 3479.
  • A telephone line that is directed at the conference server on the Internet to facilitate telephone calls into the virtual court.
