lecture recording
Lecture recording refers to the process of recording and archiving the content of a lecture, conference, or seminar.〔Thomas, R., Comparison of Distance Education/Communication Technologies, http://www.aces.edu/ctu/techref/video/DistanceEdTech.pdf〕 It consists of hardware and software components that work in synergy to record audio and visual components of the lecture.
==Hardware==
Hardware is used to capture the lecturer's voice along with the video of the lecturer. Sometimes, the lecturer may use visual aids to support their speech, such as slide shows, which are presented to the audience with some kind of projector. In this case, such slide shows can also be recorded. Once captured, the data is then either stored directly on the capture hardware or sent to a server over a LAN or the Internet. After some processing to adapt the video formats to the desired distribution mechanism, codecs, etc., viewers are then able to remotely access the recording, either in real time or ex post facto.
The recording of a lecture or presentation may use any combination of the tools: Microphone, Camera, Screen capture, Presentation capture, or Document camera.
