Concept
Lecture recording
Summary
Lecture recording refers to the process of recording and archiving the content of a lecture, conference, or seminar. It consists of hardware and software components that work in synergy to record the audio and visual components of the lecture. It is widely used in universities and higher education in the UK and Australia to provide support for students. 71% of institutions responding to a UCISA survey in 2016 indicated that this technology was available in their institution. Where lecture recording is done at scale, the recording system may be integrated with the timetabling system and the collection of metadata may be automated.
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 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 live stream or video on demand.
The recording of a lecture or presentation may use any combination of the following tools: Microphone, Camera, Screen capture, Presentation capture, or Document camera.
Software is used both on the capture hardware, the viewer's computer, and the production server. Software ranges from simple web browsers and video players to stand-alone software programs made specifically for viewing lectures. The viewer's as well as the presenter's software must be compatible with the software on the server which receives the content from the capture hardware, produces it, and sends it to the viewer's computer on-demand. OpenCast is an open-source video capture system available in higher education.
Modern lecture recording software supports advanced features such as indexing through OCR, instant search, real-time video editing and annotation, along with other advanced features.
