The Research And Implementation On Real Time Generation Of Multimedia Coursewares System

With the rapid development of information technologies and popularization of multimedia technologies bring more vitality to education field. And in this field multimedia coursewares are using more widely and get more attention. Therefore, the main purpose of this paper is to combine the multimedia technologies and computer applied technologies, then it can impel the multimedia coursewares in the classroom instruction popularization and application, optimize teaching process and teaching effect and achieve the better teaching goals.The paper designs and develops a platform with low cost and strong practicability for multimedia coursewares. In this paper, first of all, I simply introduce the key technologies of this system, such as stream media, Windows Media Service, ASF files framework, and then introduce the design aim of this system, the whole design and interface design according to the main functions. At last, I introduce the detailed realization process, including collecting and compressing sound-video frequency, realization of white-board function, in-phase realization of sound-video frequency and electronic lecture, conformity of sound-video frequency and electronic lecture. Especially, the white-board function enriches flexibility of classroom teaching during realizing process. The key point of this system is in-phase realization among different multimedia files. So there are detailed introduction of in-phase realization and concrete realization flow in this paper. After repeatedly testing, it is proved that this system had implementated the expected effects.Then,it provides an easy operating flat to courseware makers. Therefore, it will shorten producing period and improve work efficiency. This system can be used by common teachers.The system has many other good features, such as low exploiting cost, strong compatibility and usability, so it has a widely application future.
