| Video Resources Online Course Study and Research Framework
[Abstract] This paper analyzes and discusses the building of a network video resource is an innovative curriculum resource structure of the new growing point of the construction, combined with the latest technological developments and the needs of teaching practice presents a curriculum based on local area networks construction of video resources framework, which integrates information acquisition systems, streaming media technology, knowledge-based classification of points, or time slice storage of metadata associated with teaching. In addition, local area network course discusses the video-based resources related applications means. [Key words] frame model metadata slice video resources I. Introduction China's thesis League finishing. Course of a web-based online teaching has developed a few years, the state is far from ideal. The number of students from the network point of view of teaching social learners share a very small proportion. Go into the underlying reason is that online teaching course content and form of learning can not meet the actual needs. From the school's internal point of view, the demand for online course with China's educational reform,nike sale, are also very urgent to improve the point. Improve the teaching quality of education need to build a full online course library, and a complete online course database, which can only be said that the network of electronic materials, rather than network programs. We can see, network programs, is the process of information about teaching is the core business of education, information technology base. The next decade,mulberry bags sale, the only way for all kinds of educational information, that is, during the first classroom face to face information and network. Therefore able to establish a standard online course, is the basis of educational information. A complete online course materials, complete course should not only include text data, the most important is to build online course videos, which can really make the network programs in the social teaching and improve teaching will play a very key positions. Learning resources on the metadata specification, the foreign started in 1997, and is under study and did not achieve the perfect level. As these norms and standards are being developed, there is no official standard release form, which is a relatively complete model of IEEE's LOM, which provides for study in the WEB page presents resources, which should provide some of the basic elements, but does not require the implementation of these meta-data, such as their architecture, editing language, data access methods. Second, the framework of the study and discussion address the problem, this study combines the latest technological developments and resources to application requirements, try innovative video resources online course work ideas, propose a course for the local area network Video resource portal-building framework: 1. video resource portal frame model using client / server model architecture. Its three-tier model of the entire workflow from the form. (1) data acquisition system. Main function is to achieve large-scale video capture normal classroom teaching and teaching material acquisition, and knowledge-based unit of point or time slice, according to the metadata has been associated with teaching of classification (compression, etc.) sent to the resource storage system or direct broadcast. Mainly from the classroom video recording system, course video analysis tools and other accessories. (2) resource storage system. Main function is to achieve high-speed mass data storage and retrieval. Will be collected to classify high-quality video storage and labeling index, using streaming media technology a network of video resource library. Used streaming solution has the advantage of reducing network bandwidth share,herve leger dress sale, reduce the burden on the server to ensure smooth transmission of video. (3) user applications. Main function is the online course through the browser for rendering. Various end-users (teachers, students, parents, leaders, administrators, etc.) with your own personalized application requirements,ghd australia, application of various functional modules.
