网络课程建设原则与流媒体技术的应用策略探讨

Exploring the Principles of Network Courses and the Strategies of Applying Streaming Media Technology

网络课程利用流媒体技术实现网络实时传输,具有十分广泛的应用领域。网络课型建设应确立实用性、分层、科学性与动态性四项原则,应建立五个层次的网络课型体系及其视、音频流的度量起始尺度和标准。流媒体技术则应根据不同类型课程的要求,分别采用Real Media、Twopass Encoding、Windows Media、QuickTime、FLV等不同范式,以拓宽教学视野与空间,为网络教育提供优质条件与环境,促进网络课型的建设与发展。

It can be practiced in a wide range of fields to apply streaming media technology in network courses to achieve real--time network transmission. Constructing network courses should follow such principles as practicality, hierarchy, scientific and being dynamic. And network courses should be classi- fied into five levels of different courses and of the initial measurement scales and standards for its visual and audio stream. In accordance with the requirements of different network courses, streaming media technology should use Real Media, Two pass Encoding, Windows Media, QuickTime and FLV respectively in order to provide favorable conditions and environments by broadening the horizons and space of teaching, and eventually promote the construction and development of network courses.
