我们的目标是帮助自动捕获讲座并将其广播给远程观众。这种系统的设计有两个相互关联的组成部分。技术组件包括硬件（例如，摄像机）和相关软件（例如，扬声器跟踪）。美学组件体现了人类摄像师遵循的规则和习惯用法，以使视频在视觉上引人入胜。我们提出了一个演讲室自动化系统和大量的新的视频制作规则，从专业摄像师谁批评它。我们还描述了不同的摄像机的数量和类型的各种演讲室环境的规则。我们将进一步讨论专业摄像师所做的与当今技术可行性之间的差距。
Our goal is to help automate the capture and broadcast of lectures to remote audiences. There are two inter-related components to the design of such systems. The technology component includes the hardware (e.g., video cameras) and associated software (e.g., speaker-tracking). The aesthetic component embodies the rules and idioms that human videographers follow to make a video visually engaging. We present a lecture room automation system and a substantial number of new video-production rules obtained from professional videographers who critiqued it. We also describe rules for a variety of lecture room environments differing in the numbers and types of cameras. We further discuss gaps between what professional videographers do and what is technologically feasible today.
