备注

新型冠状病毒肺炎疫情改变了人们的生活方式,迫使人们必须保持一定的社交距离甚至互相隔离.教育科研作为传统的需要人员聚集的活动,受到了很大的冲击.线上教育成为疫情期间教育科研的主要方式,这些方式普遍依赖网络视频技术.教育科研的场景五花八门,网络视频技术亦种类繁多.对不同的教育科研场景进行了合理的归纳分类,并采用最合适的网络视频技术为这些教育科研活动的线上进行提供了解决方案.

The COVID-19 pandemic changes the mode of life, and forces people to keep social distance or even separate from each other. Education and research, as a type of activities that usually needs many people gather at the same space, need network video technologies to keep participants separating from each other. In this paper, we analyze three different types of education and research activities, and try to give the appropriate solutions of the network video technologies for each particular activity.
