Design And Implementation Of Court Digital Courtroom Image System

With the continuous development of computer technology, multi-media and network technology is updated, the court informatization construction, especially the digital court will face greater technological innovation situation, in the audio and video processing effect, data storage and so on will further enhance the technology.The main purpose of this paper is to study the design and implementation of digital multimedia technology and computer network technology based on the extension,extension of the trial court, through the traditional function, using advanced computer network technology and multimedia technology, digital court system in the trial,evidence shows, Sulu digital video and audio recording, storage, playback and control the integrated management system and online remote arraignment, remote trial as the main application, in order to adapt to the new needs of the trial, the people's court trial to achieve a comprehensive management work of informatization.This paper starts from the information system development status of domestic and foreign courts, through systematic analysis and research, put forward the development direction of digital court court. The main technology of the system design is the audio and video streaming media technology, including multimedia file format, video codec technology, audio codec technology. Follow the design of multimedia transmission requirements for the network, using HTTP protocol and its working principle, support streaming media transmission network protocol. At the same time the system design also uses the multicast technology and TCP/IP port number and protocol. The system uses C/S structure, database using SQL2008.The overall design of the system analyzes the principles of database design,system of structure design, The hardware design of the system includes the system of the front-end part of the design, system design and system storage part to transmission part design. The system module is divided into the trial recording module, the video playback module, electronic record function module and system management module.The detailed design of the system is mainly C/S model Winsock program design,system function module detailed design, system architecture, live streaming media data wave transmitting module, video data receiving module, video playback module design; detail design and detailed design of the client system video server, including initialization multicast socket, multi window design and Direct show display module.This paper obtains a trial image recording, transmission and preservation of thetechnique in the analysis, at the same time in this context developed an initial system,the main function is to complete the trial process of recording sorting, then transfer to the online sharing, so with the help of the internet no matter what type of users can choose to watch the process of trial In addition to the course of the trial record in order for the audio and video data, as streaming media data, and then the court cases stored in the database, so that later used in the network..
