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 trials.
Sound reinforcement system: power amplifier, speaker.
Signal input: SDI high-definition cameras, physical exhibition booths, and dedicated computers for trials are used for signal input.
Trial management system: Remote trial management host and centralized control system.
Information display function of the interrogation room
The main display of the courtroom adopts two 55-inch LED monitors. They are used to display the current remote interrogation screen and locally synthesized image. The displayed image simultaneously meets different application requirements such as multi-screen synthesis for interrogation, single-screen evidence display, and multi-screen evidence synthesis.
Audio collection and processing function in the interrogation room
Equipped with 2 microphones, 1 amplifier, and 2 wall-mounted speakers. The remote interrogation 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 interrogation room
The signal types involved in remote interrogation include computer signals, SDI camera signals, DVD signals, HDMI signals, etc. The remote interrogation host performs unified fusion processing on these signals to achieve full digitization of the entire chain from image acquisition, processing, transmission, and display at the front end. Any image or multiple synthesized images can be freely switched and displayed on any display terminal in the interrogation room or sent to the remote interrogation room.
Video image capture: One 1080P high-definition SDI camera is used to capture video images of the interrogating personnel. After being processed by an image processor, it is displayed in multiple screens for output. It features broadcast-grade image quality, 1080P clarity, and a 20x optical zoom lens. It supports high-definition digital HD-SDI output interface.
Other image signal acquisition: A physical booth is set up, which supports HDMI, VGA, and other outputs, with a resolution of up to 5 million pixels. It can be used for displaying physical evidence. One DVD, supporting HDMI, VGA, and other outputs. All images, after processing, can be freely displayed on large-screen display terminals and remote interrogation rooms. Multi-screen synthesis and seamless switching processing can be performed 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 interrogation host. The physical exhibition booth displays the physical evidence.
Centralized control function of the interrogation room
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 interrogation control equipment. Be able to centrally control the interrogation room equipment through local control.
During the interrogation process, the control personnel can meet the interrogation requirements with just one click.
When using the trial equipment normally, except for actions such as picking up and placing CDs and opening exhibition booths, all other operations of the trial equipment are automatically completed by the system, including the control of the switching system, the use of video recording equipment in the courtroom, and the switching of various evidence signals.
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 interrogation:
The video encoding format uniformly adopts H.264 encoding. The interrogation information is automatically stored. During the interrogation process, all live or rebroadcast streams are standard RTSP streams. After the interrogation is completed, the stored video files can be played back locally or copied and burned.
Real-time encoding of interrogation audio and video information can be achieved. Support the collection, encoding, live streaming, and storage of multiple images (two or more) and evidence images during the entire interrogation process. The synthesized image resolution is 1080P (1920 × 1080).
