The Design And Implementation Of The Audo And Video Resources Shareing System On SSI Framework

With the rapid development of information technology, the internat has become animportant platform for the information exchange, the information of educationtechnologies has become more and more improtant to the colleges and universities, soto build a digital campus of the colleges and universities become an important topic.The traditional teaching methods can not meet the needs of the college teachers andstudents, they need an information exchange platform, according to the demand of theBeijing University of Technology,to set up an audio and video system with sharedresources is necessary. This issue of the ultimate aim is to establish an audio andvideo resources sharing system, the system for university teachers and students toupload the audio and video resources, playback and review platform.The research of this project starting from the development of audio and videoresources sharing system technology, the system’s technical route are Struts2, Springand iBatis three J2EE framework, so that the system has good scalability andflexibility. Combined the Ajax, jQuery and Sitemesh, assistive technologies toimprove the friendliness of the front interface. After analysis of the departure from thesystem requirements, the design of the system structure and system business logic,while the design of the system into the structure of the database, to enable the systemto develop more specific. In terms of innovation, the system has its own ad hoc, suchas user self-upload statistics, automatic transcoding and system resources.In the system process of research and development process, the author carried out anumber of exploration and research, and solved many of the key issues. For example,the core of the system is an integral part of the transcoding the audio and videoresources, using a combination of FFmpeg and MEncoder, and the multi-threadingtechnology to achieve transcoding; audio and video resources upload into FTP uploadand upload web pages to meet the different users file sizes demand; Variety of labelclassification, including the System tab, the classification labels and custom labels tomeet the diverse needs of different users, facilitate the user’s search query.This topic for university teachers and students a good learning platform, the systemvideo resources uploaded by administrators and teachers and students, and thentranscoding and audit through the background, to ensure the health and effectivenessof the audio and video resources, through the review of audio and video resources canachieve the purpose of the exchange of learning.
