Lecture Recording
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 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 replying 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 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Recording And Reproduction
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to ...

Data
In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted. A datum is an individual value in a collection of data. Data is usually organized into structures such as tables that provide additional context and meaning, and which may themselves be used as data in larger structures. Data may be used as variables in a computational process. Data may represent abstract ideas or concrete measurements. Data is commonly used in scientific research, economics, and in virtually every other form of human organizational activity. Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represents the raw facts and figures which can be used in such a manner in order to capture the useful information out of it. ...

UCT Leslie Social Science Lecture Theatre Class
The University of Cape Town (UCT) ( af, Universiteit van Kaapstad, xh, Yunibesithi ya yaseKapa) is a public research university in Cape Town, South Africa. Established in 1829 as the South African College, it was granted full university status in 1918, making it the oldest university in South Africa and the oldest university in Sub-Saharan Africa in continuous operation. UCT is organised in 57 departments across six faculties offering bachelor's ( NQF 7) to doctoral degrees ( NQF 10) solely in the English language. Home to 30 000 students, it encompasses six campuses in the Capetonian suburbs of Rondebosch, Hiddingh, Observatory, Mowbray, and the Waterfront. Although UCT was founded by a private act of Parliament in 1918, the Statute of the University of Cape Town (issued in 2002 in terms of the Higher Education Act) sets out its structure and roles and places the Chancellor - currently, Dr Precious Moloi Motsepe - as the ceremonial figurehead and invests real leadership ...

Document Camera
Document cameras, also known as visual presenters, visualizers, digital overheads, or docucams, are real-time image capture devices for displaying an object to a large audience. Like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, in essence, high resolution web cams, mounted on arms so as to facilitate their placement over a page. This allows a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches. Theoretically, all objects can be displayed by a document camera. Most objects are simply placed under the camera. The camera takes the picture which in turn produces a live picture using a projector or monitor. Different types of document camera/visualizer allow great flexibility in terms of placement of objects. Larger objects, for example, can simply be placed in front of the camera and the camera ...

Presentation Software
A computing, a presentation program (also called presentation software) is a software package used to display information in the form of a slide show. It has three major functions: * an editor that allows text to be inserted and formatted * a method for inserting and manipulating graphic images and media clips * a slide-show system to display the content Presentation software can be viewed as enabling a functionally-specific category of electronic media, with its own distinct culture and practices as compared to traditional presentation media (such as blackboards, whiteboards and flip charts). Presentations in this mode of delivery have become pervasive in many aspects of business communication, especially in business planning, as well as in academic-conference and professional conference settings, and in the knowledge economy generally, where ideas are a primary work output. Presentations may also feature prominently in political settings, especially in workplace politic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screencast
A screencast is a digital recording of computer screen output, also known as a video screen capture or a screen recording, often containing audio narration. The term ''screencast'' compares with the related term ''screenshot''; whereas screenshot generates a single picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, that can be enhanced with audio narration and captions. Etymology In 2004, columnist Jon Udell invited readers of his blog to propose names for the emerging genre. Udell selected the term "screencast", which was proposed by both Joseph McDonald and Deeje Cooley. The terms "screencast" and "screencam" are often used interchangeably, due to the market influence of ScreenCam as a screencasting product of the early 1990s. ScreenCam, however, is a federal trademark in the United States, whereas screencast is not trademarked and has established use in publications as part of Internet and computi ...

Camera
A camera is an Optics, optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a Image sensor, digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A Shutter (photography), shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera dom ...

Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presentation
A presentation conveys information from a speaker to an audience. Presentations are typically demonstrations, introduction, lecture, or speech meant to inform, persuade, inspire, motivate, build goodwill, or present a new idea/product. Presentations usually require preparation, organization, event planning, writing, use of visual aids, dealing with stress, and answering questions. “The key elements of a presentation consists of presenter, audience, message, reaction and method to deliver speech for organizational success in an effective manner.” Presentations are widely used in tertiary work settings such as accountants giving a detailed report of a company's financials or an entrepreneur pitching their venture idea to investors. The term can also be used for a formal or ritualized introduction or offering, as with the presentation of a debutante. Presentations in certain formats are also known as keynote address. Interactive presentations, in which the audience is involved ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video On Demand
Video on demand (VOD) is a media distribution system that allows users to access videos without a traditional video playback device and the constraints of a typical static broadcasting schedule. In the 20th century, broadcasting in the form of over-the-air programming was the most common form of media distribution. As Internet and IPTV technologies continued to develop in the 1990s, consumers began to gravitate towards non-traditional modes of content consumption, which culminated in the arrival of VOD on televisions and personal computers. Unlike broadcast television, VOD systems initially required each user to have an Internet connection with considerable bandwidth to access each system's content. In 2000, the Fraunhofer Institute IIS developed the JPEG2000 codec, which enabled the distribution of movies via Digital Cinema Packages. This technology has since expanded its services from feature-film productions to include broadcast television programmes and has led to lower bandw ...

Livestreaming
Livestreaming is streaming media simultaneously recorded and broadcast in real-time over the internet. It is often referred to simply as streaming. Non-live media such as video-on-demand, vlogs, and YouTube videos are technically streamed, but not live-streamed. Livestream services encompass a wide variety of topics, from social media to video games to professional sports. Platforms such as Facebook Live, Periscope, Kuaishou, Douyu, bilibili and 17 include the streaming of scheduled promotions and celebrity events as well as streaming between users, as in videotelephony. Sites such as Twitch have become popular outlets for watching people play video games, such as in esports, Let's Play-style gaming, or speedrunning. Live coverage of sporting events is a common application. User interaction via chat rooms forms a major component of livestreaming. Platforms often include the ability to talk to the broadcaster or participate in conversations in chat. Many chat rooms also consist ...

Remote Desktop Software
In computing, the term remote desktop refers to a software- or operating system feature that allows a personal computer's desktop environment to be run remotely off of one system (usually a PC, but the concept applies equally to a server or a smartphone), while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration. Overview Remote access can also be explained as the remote control of a computer by using another device connected via the internet or another network. This is widely used by many computer manufacturers and large businesses help desks for technical troubleshooting of their customer's problems. Remote desktop software captures the mouse and keyboard inputs from the local computer (client) and sends them to the rem ...
