Application of WIS-HDCAP1.0 HD VGA capture card in digital court
---- Weiss Technology: Presenting HD Digital Vision
Accompanying the digital court are all kinds of IT equipment. Will clerks and other court staff get busy with the operation of the equipment? It depends on the level of program design.
At the same solemn court trial site, a lot of IT equipment was not available before.
The solemn court is difficult to associate with high-definition video equipment. Now, various digital devices faithfully record the actions of the participants in the court hearings.
Liberation clerk
In the early stage of the construction of the digital court system, the court mainly installed some electronic equipment in the court, such as conference audio, video cameras, large-screen displays, physical exhibition stands, computers, CD-ROM burners, etc. The main feature of the system is that it simply meets the requirements of the trial personnel and The audiovisual experience of the participants in the litigation and the need for evidence display of some new materials have also achieved the CD-ROM recording of the trial process and the preservation of the case file. With the increase of electronic equipment, the workload and complexity of the clerks to operate and manage the equipment are also increasing. At the same time, the information of the trial entity is stored in the original medium, which is inconvenient for subsequent use and cannot play the use value after the collection of the trial information.
In order to solve the problems of electronic equipment operation and management, and free the clerk from the heavy operation, the centralized control system of the equipment should be added on the basis of simple electronic in the later stage of system construction, and the equipment linkage should be carried out according to the needs of the court hearing process. The application of centralized control system greatly improves the manageability and operability of the court support environment, improves the availability of various electronic devices, and reduces the complexity of the clerk's work, so that the clerk can better focus on the court trial record.
In order to realize the storage management and utilization of court trial information, the digital court system adds the management system application software required by the court trial process on the basis of centralized control of the equipment, through the application software and hardware, information and process combination, court trial on-site support and The combination of background processing realizes a real digital court.
Function is positioned to reduce complaints
The composition of the digital court mainly includes court trial management software, court support environment and centralized control system, collection and storage system, audio and video live on-demand system and system platform. From the perspective of trial business application support and assistance, the functional positioning of the digital court mainly includes the following aspects:
1. Provide proof and demonstration functions to meet the growing new demand. By configuring multimedia evidence display equipment and computer terminals to display various types of evidence stipulated by law, support court debates and case explanations and demonstrations, so that the parties, observers, and members of the collegiate bench can have an intuitive, personal, and comprehensive feeling about the case, Different geologic evidence can also be realized through computer network technology to solve problems such as the difficulty of providing evidence and the difficulty of witnesses giving evidence.
2. Realize digital recording and storage in multiple formats such as text, audio and video, and can reproduce the trial process through playback to improve the transparency of the trial. For large and important cases, with large social impact, complicated case, unclear application of laws, or new-type cases, the use of video and its processing technology can completely record and store the images and sounds of each stage of the court process. This aspect provides proofreading benchmarks for the accuracy of the court trial transcripts. On the other hand, the court trial process can also be reproduced through video on demand. The reappearance of the trial process can provide courts with trial supervision, case reference, judge evaluation, case learning and other applications, which further improves the transparency of the trial and facilitates the public to supervise the trial process.
3. Realize the delivery of the judgment documents of the case closed in court, reduce the litigation of the parties and improve the work efficiency. At present, civil cases account for more than 70% of the total number of cases tried by the people ’s courts. For criminal cases with clear facts, conclusive evidence, minor crimes, and civil cases with clear facts and obvious relationship between rights and obligations, the system supports court-settled cases and document production , Seal printing, serving in court, etc., to achieve the purpose of convenient litigation.
4. Realize the information management of the court trial process management and control, and improve the capacity of court trial management. Starting from the preparation before the court, the hearing of a case generally goes through several stages: opening a court, court investigation, debate, cross-examination, recess, and closing the court. The system provides information tools for court judges such as presiding judges and clerks to meet the information acquisition needs and information display needs of various roles at different stages of the case trial, such as basic information of the case and transcript information.
5. Transcripts of court hearings and proofreading. The clerk can perform court trial transcripts and proofreading. During proofreading, the court trial video can be played back. After proofreading, the transcript can be printed in court.
6. The live video on-demand function provides support for remote trial, heterogeneous evidence, and protection of vulnerable witnesses on the one hand, on the other hand, it can further expand the scope of the open trial and improve the transparency and fairness of the trial.
7. Centralized system management and operation to reduce system maintenance. There are many devices involved in the digital court, and the operation of various devices may also be cumbersome. In order to improve the trial efficiency, it is necessary to simplify the operation and management of the various equipment in the court according to the needs of the court trial and the trial process, and minimize the equipment operations of the litigants. The digital court should implement intelligent linkage between devices according to the needs of the court hearing process.
8. After the combination of the digital court system and the trial information management system, on the one hand, the digital court system can make full use of the case information in the trial information management system; on the other hand, the audio and video information of court hearings generated by the digital court, transcripts of court hearings and other information can be compared with The sharing of information such as audio and video live on-demand system, trial information management system, electronic file system, etc., lays the foundation for the application of the system.
Not just video equipment
The construction of the digital court system should not be a pile of simple audio and video equipment, but should start from the practice of court trial business, fully meet the needs of the relevant participants in the trial process, and realize the data and management of the court trial management information system. Completely integrated. The digital court must make full use of the data in the court's integrated information system, and the data information generated by the digital court must be able to be added to the court's integrated information system to avoid the formation of new information islands. For example, the court trial case information (such as case number, case undertaker, case name, parties, etc.) can be directly extracted from the existing trial management system, and the trial audio and video information and court trial records generated during the trial process can be directly returned to the trial The business management system realizes the substantive management of cases and lays the foundation for the comprehensive utilization of subsequent court hearing information.
The configuration and deployment of equipment in the digital court should be based on the principle of reasonable combination of business needs and actual environment. Instead of one-sided pursuit of the advanced nature of the system, it should focus on the application of the system, such as the number of cameras and the location of the deployment and how the area photographed is combined How to store and select live images for multiple cameras in the same court.
Due to the non-repeatability of the court hearing process, the high reliability of the court hearing system must be guaranteed. In the event of network failures, equipment failures, etc., the system should take effective measures to ensure that the audio information of the court hearing can be completely recorded.
The system construction process must strictly abide by the relevant standards and specifications of the court industry informatization. For example, the digital streaming media file format of the court trial should adopt the mainstream format and combine different application scenarios. It is necessary to fully consider the image quality, storage space, access method, and playback. Tools etc.
