The Design And Implementation Of Digital Multimedia Exhibition Management System

With the popularization of flat panel displays such as plasma and LED, as well as the advancement of network streaming media, there are new demands in the use, management and dispatch of display screens for current enterprises. Therefore, an integrated display system featuring multimedia data organization management, content control and digitalization should be quickly adapted for the internal use of enterprises. This thesis studies the design and implementation of digital multimedia exhibition management system, the main work is as follows:First of all, introduced the domestic and foreign development status and the latest progress of digital multimedia, lightweight Web framework are analyzed, including the authentication security framework, database caching, integrated management tools and front-end framework, video codec technology basic principle, then introduced the FFMpeg video codecs and SDL display function, as well as communication principle based on Socket protocol and XML data format.Secondly, analyzed the actual demands of display system, the system architecture design and function design were based on this. The system is based on B/S architecture, respectively the presentation layer, application layer, component services layer and data layer. The function module was divided into server side and client side, the server side includes website and server controller, the client side includes client controller and player. Provided detailed design and implementation of two core modules, the website and the player, the website also contains controller module that deployed on the client and the server respectively. Expounds the detail implementation of sub-modules, including media data management, security management, playlist management, etc. Analyzed the requirement of player and the realization of the audio and video decoding, display and synchronous, made design for the corresponding database.Finally built the test platform, and run functional test and performance test on it, the test results show that the system functions meet the design requirements, the system's stable and has reached the requirement of enterprise operation.Display screen has been effective managed and controlled by using multimedia management system, the administrator can avoid a lot of repeated work. For the enterprise, the system can improve the utilization ratio of the terminal equipment while saving the labor cost, strengthen the display effect and enhance its corporate image.
