Hardware of the review room

Display system: The standard digital courtroom uses two LCD displays as the trial display.

Audio collection: Capacitive gooseneck microphone, audio processor, and effect processor are used for audio collection during review.

Sound reinforcement system: power amplifier, speaker.

Signal input: SDI high-definition camera, physical exhibition booth, dedicated computer for review.

Review management system: remote review management host, centralized control system

Information display function of the review room

The main display of the court adopts two 55 inch LED monitors. Used to display the current remote review screen and locally synthesized image. The displayed image simultaneously meets different application requirements such as multi screen synthesis for review, single screen evidence, and multi screen evidence synthesis.

Audio collection and processing function in the review room

Equipped with 2 microphones, 1 amplifier, and 2 wall mounted speakers. The remote review host processes the collected audio in real-time and outputs it to the sound reinforcement system through the host

Video capture and processing function in the review room

The signal types involved in remote review include computer signals, SDI camera signals, DVD signals, HDMI signals, etc. The remote review host performs unified fusion processing on these signals to achieve full digitization of the entire image acquisition, processing, transmission, and display chain from the front-end. You can freely switch any image or multiple synthesized images to be displayed on any display terminal in the examination room or sent to the remote examination room. Video image capture: One 1080P high-definition SDI camera is used to capture video images of the reviewing personnel. After being processed by an image processor, it is displayed in multiple screens for output. Featuring broadcast grade image quality, 1080P clarity, and a 20x optical zoom lens. Support high-definition digital HD-SDI output interface; Other image signal acquisition: Set up a physical booth that supports HDMI, VGA, and other outputs, with a resolution of up to 5 million pixels. Can be used for displaying physical evidence; One DVD, supporting HDMI, VGA, and output. All images have been processed and can be freely displayed on large screen display terminals and remote examination rooms. They can perform multi screen synthesis and seamless switching processing on 1080P high-definition cameras and computer signals in the courtroom.

Trial evidence information display function

The evidence computer displays the electronic evidence (electronic text, electronic images, audio and video information) of the case through video output to the review host, and the physical exhibition booth displays the physical evidence.

Centralized control function of the review room

(1) Local control function: Connect the control circuits (RS232/RS485) of high-voltage equipment and local physical exhibition booths, cameras, LCD screens, and other devices to the review control equipment, and be able to centrally control the review room equipment through local control.

(2) During the review process, the control personnel can meet the review requirements with just one click.

(3) When using the trial equipment normally, except for actions such as picking up and placing CDs, opening exhibition booths, etc., all other operations of the trial equipment are automatically completed by the system, including the control of the switch system, the use of video recording equipment in the courtroom, and the switching of various evidence signals.

(4) When shutting down the system, all circuits except for the central control circuit are powered off; Reflecting the social theme of energy conservation, emission reduction, and rational utilization of resources.

Information encoding and storage function for review

(1) The video encoding format uniformly adopts H.264 encoding, and the trial information is automatically stored. During the trial process, all live or rebroadcast streams are standard RTSP streams. After the trial is completed, the stored video files can be played back locally or copied and burned;

(2) Real time encoding of trial audio and video information can be achieved. Support the collection, encoding, live streaming, and storage of multiple images (2 or more) and evidence images during the entire review process, with a synthesized image resolution of 1080P (1920 × 1080);
