英文摘要	投影机呈现的信息与教师发出的视觉注意引导信息共同构成屏幕信息。目前,包括视频公开课在内的课程随堂录像,教师发出的视觉注意引导信息几乎全被忽略,缺失的屏幕信息使受众困惑。通过增设屏幕摄像机,为重构的视觉注意引导信息提供准确的屏幕位置、进入、退出时间点、延续时长等依据。在视频同步编辑中,运用非线性编辑系统中的各种视频表达方法,使教师发出的视觉注意引导信息超越现场的表现方式,让远程学习的受众准确、形象、适时地感受到视觉注意引导信息,达到了完整屏幕信息远程传播的目的。; Screen information consists of information displayed by the projector and visual attention guiding information.At pr esent,in classroom course videos,including videos of open lessons,almost all visual-attention guiding information sent out by the teacher is neglected,and the lack of screen information confuses the audience.Setting up screen cameras can provide ac curate screen positions,times of entry and exit,and running duration for the textual and graphic reconstruction of visual-attent ion guiding information.In synchronized video editing,the various video expression methods in the nonlinear editing system t o enable the visual-attention guiding information sent out by the teacher to exceed the on-site presentation methods,allowing the audience in distance learning to capture the information accurately,vividly and immediately,thereby achieving the purpose of remote transmission of full screen information.
