双向视频远程教学系统及其应用

Bi-directional video distance teaching system and its applications

应用双向视频构建远程教学系统,具有较好教学效果的特点,但也存在建设投资大、运行成本高等不足,一定程度上阻碍了该技术的推广应用。宁波电大采用AVCON双向视频技术构建远程教学系统,建设投资省、无运行通信费用、教学效果好,且它可与学校已有教学设施相配,使其应用效果更加突出。本文从技术实现角度,简单介绍了宁波电大双向视频远程教学系统及其与已有教学设施配合的应用实践,具有明显的应用特色和参考意义。

The application of the bi-directional video into distance teaching system possesses the features of offering comparatively good teaching effects, but it also has some shortages such as high costs in investment and system operation, thus preventing it from being widely used to a certain degree. The AVCON bi-directional video distance teaching system built up in Ningbo Radio & TV University (NBRTVU) is characterized with lower construction cost, no running communication fee, and satisfactory teaching effects. In addition, it can well match with the existing facilities and equipment of the school, therefore, its application advantages are very obvious. From the angle of the realization of the techniques, this paper briefly introduces the bi-directional video distance teaching system utiliozed in NBRTVU, as well as its remarkable characteristics and possible significance in its application and practice in matching with the existing facilities and equipment of the school.
