The Design And Implementation Of Flash Network Advertisement Teaching System Based On Mobile Platform

With the continuous development of our economy and the progress of the society, there is an increasing demand for knowledge. Need through the daily learning to meet the social demands for their skills and knowledge structure, information technology and computer network technology has developed to a new stage, the mobile client already deep into all areas, expansion of mobile learning mobile learning and distance education has become a thriving research field, it is on the basis of digital learning through effective combination of mobile computing technology, can make learners in anytime convenient access to their own needs of knowledge information, realize in the true sense of autonomous learning, finally realizes the socialized and lifelong learning.This article is based on the mobile platform to the teaching of the network learning Flash system has carried on the design and development of related research, the current development of the network using mature mainstream technology, combined with Java and SQL database technology, design and develop a Flash online advertising system for mobile learning. Using the principle and method of software engineering, the developed system has carried on the demand analysis, get the system functional requirements, and use UML object-oriented modeling technology, gradually shows the system use case diagram and class diagram, and has carried on the overall design of the system. Then has carried on the system function module design, the system is divided into several main function modules, also in the general design of the system architecture design and the system database design of the key techniques such as the analysis and design. For motion estimation in video coding module search algorithm optimization and improvement, corresponding scheme for reference in the software algorithm and improved algorithm scheme comparison, improved algorithm is reference algorithm in software solutions are obtained in terms of video quality and coding time has certain improvement and improve.In the development process according to the characteristics of the mobile development for single sign-on technology, Service component technologies, system underlying network communication protocol, data format, embedded database technology and XML parsing technology key problems were studied respectively, and the last in a simulated environment to realize the function of the mobile learning platform terminal of each module. Through the use of the terminal platform, mobile phone users can according to the selective access to rich content online Flash of teaching resources, can through online real-time module discussion and problem solving, answering questions by the single sign-on technology can easily enter the learning platform, by automatically remind module can study timely and effective access to important information. Then, for h. 264 video data encapsulation strategy has carried on the comprehensive analysis, designed by RTP encapsulation process and strategy, according to RTP encapsulation h. 264 video stream data for transmission error control in the process of design a Qos solution. In the implementation part of the system including the selection of the development environment, the realization of the system database access, main function modules of the specific implementation, module implements key code. Finally, the system was tested and the test results of system is analyzed, system test results show that the system is good for user demand, the overall performance to achieve the design goal of the system.
