DCR-VC Minimum requirements

Hybrid and Virtual Courtrooms – Digital Court Recording

Technical Overview

DCR Virtual Courtroom (DCR-VC) facilitates the recording of audio, and optionally video, during virtual courtroom sessions conducted over the internet or traditional telephone lines by courts of record.

Distinguishing itself from general-purpose conferencing systems, the DCR system captures each participant’s audio and video into individual channels. This segmentation enables transcriptionists to accurately transcribe and certify court session transcripts.

In a DCR-VC setup, remote participants initially connect to a Conference Server and await connection to the courtroom by court staff using the conference manager window within the program. Remote participants have limited functionality and cannot initiate sessions with the courtroom; all participation is initiated by court staff.

The Conference Servers serve as conduits and do not retain transmitted data. Recording files are exclusively stored on the recording computer, with no data saved elsewhere. All transmitted data, including audio/video, is encrypted using protocols defined in the U.S. National Institute of Standards and Technology (NIST) Special Publication 800-131A.

Access to a DCR Conference Server is exclusive to courts subscribed to the DCR Virtual Courtroom system, with servers hosted by BIS Digital in various geographic regions.

Minimum System Requirements
  • An internet connection with 15 Mbps upstream and 15 Mbps downstream.
  • A method for applying Acoustic Echo Cancellation (AEC). BIS Digital can integrate or provide one or more Digital Signal Processors (DSPs) to facilitate this function when a physical room with peripheral equipment is used.
  • The system employs UDP for communication over one of the following ports to establish communication with the DCR Conference Server: 2469, 3478, 3479, 3480, 3481, 5004, 8801, 8889, or 9000 (UDP). The default port is 3479.
  • Windows 10 or later, i5 processor model 11600 or higher, with a minimum of 8 GB of internal RAM. BIS Digital recommends the latest generation i7 and 16GB of RAM if other tasks will be performed on the PC.
Recommended Enhancements
  • Video functionality is integral to the DCR Virtual Courtroom. Should the court intend for remote participants to view courtroom proceedings, one or more cameras must be installed within the courtroom premises. These cameras may be either a conventional standard webcam or an IP camera compatible with DCR.
  • To enable courtroom attendees to see video feeds from remote participants, a sizable monitor must be provided within the courtroom. The recording computer should ideally feature a video output port, preferably HDMI, connecting it to this monitor.
  • If the court wishes to facilitate access to virtual conferences through standard telephones (excluding smartphones), setting up a suitable VoIP phone line is needed. This line may be furnished by either the court or BIS Digital.

Since 1982 the mission of BIS has been to create the best digital recording solutions available in the marketplace.
