Screencasting
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 compu ...

Screencam
ScreenCam (formerly ''Lotus/IBM ScreenCam'') is a screencast tool for Microsoft Windows that is used to author software demonstrations, software simulations, branched scenarios, and tutorials in .swf (also known as Adobe Flash) format. ScreenCam was primarily targeted at users who need to create video-oriented instructional materials who were not multimedia authors or video capture technicians. It was very easy to use, having a 'VCR-like' interface and requiring no knowledge of digital video editing, or the concept of 'frames' of a movie, because it used a different paradigm for creating the screen movies. It can also be used for creation of screencasts and conversion of Microsoft PowerPoint presentations to the Adobe Flash format. History ScreenCam was originally produced in the early 90s and received good reviews compared to other technologies of the time. It was considered one of the earliest screencasting products commercially available in the 1990s, and was popular for stream ...

The project then moved towards visual collaboration to allow sharing screenshots, gifs, annotations, and screen recordings. The first iteration included a downloadable Mac application and accompanying free service. CloudApp was later acquired by Aluminum.io and Xenon Ventures in January 2014, where Tyler Koblasa became General Manager and CEO. In June 2016, Koblasa secured ...

Crippleware
Crippleware has been defined in realms of both computer software and hardware. In software, crippleware means that "vital features of the program such as printing or the ability to save files are disabled until the user purchases a registration key". While crippleware allows consumers to see the software before they buy, they are unable to test its complete functionality because of the disabled functions. Hardware crippleware is "a hardware device that has not been designed to its full capability". The functionality of the hardware device is limited to encourage consumers to pay for a more expensive upgraded version. Usually the hardware device considered to be crippleware can be upgraded to better or its full potential by way of a trivial change, such as removing a jumper wire. The manufacturer would most likely release the crippleware as a low-end or economy version of their product. Computer software Deliberately limited programs are usually freeware versions of computer progra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Watermarking
A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal; the hidden information should,Ingemar J. Cox: ''Digital watermarking and steganography''. Morgan Kaufmann, Burlington, MA, USA, 2008 but does not need to, contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Like traditional physical watermarks, digital watermarks are often only perceptible under certain conditions, e.g. after using some algorithm.Frank Y.

Screenshot
screenshot (also known as screen capture or screen grab) is a digital image that shows the contents of a computer display. A screenshot is created by the operating system or software running on the device powering the display. Additionally, screenshots can be captured by an external camera, using photography to capture contents on the screen. Screenshot techniques Digital techniques The first screenshots were created with the first interactive computers around 1960. Through the 1980s, computer operating systems did not universally have built-in functionality for capturing screenshots. Sometimes text-only screens could be dumped to a text file, but the result would only capture the content of the screen, not the appearance, nor were graphics screens preservable this way. Some systems had a BSAVE command that could be used to capture the area of memory where screen data was stored, but this required access to a BASIC prompt. Systems with composite video output could be conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Online Lecture
An online lecture is an educational lecture designed to be posted online. Lectures are recorded to video, audio or both, then uploaded and made viewable on a designated site. Students may go to a certain designated site to view the lecture online at a time which is convenient for them. The lecture may also be available for live viewing online at the time it is recorded. Traditionally, vocal education is possible only when the teacher and the pupil are together in the same room, where the teacher passes on the information in the same vicinity of the student. The development of the online lecture makes it possible so that the teacher and student no longer have to be in the same vicinity to teach and learn, respectively. There are certain advantages to online lecturing. Students may access online lectures posted on their designated websites anywhere in the world, at any time they wish, as long as they have an internet connection. They can also be repeated for the sake of note taking. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
