A video codec is a device or software that enables video compression and/or decompression for digital video. The compression usually employs lossy data compression. Historically, video was stored as an analog signal on magnetic tape. Around the time when the compact disc entered the market as a digital-format replacement for analog audio, it became feasible to also begin storing and using video in digital form, and a variety of such technologies began to emerge.

Effective metadata adds value to information and enriches it by increasing accessibility, enhancing understanding, clarifying description, and consolidating context. Metadata can be simple or complex depending on the function it is fulfilling and the nature of the data it is supporting. Without it, the information user's ability to assess search results and select the most relevant is impaired. Hence the quality of the metadata created is pivotal to the impact and usefulness of the data collection it underpins. With the growth in the creation of information, there is an increasing need for quality metadata generation to keep pace. However, manually creating this metadata is expensive. This project aims to better understand the information search and retrieval needs of higher education so as to identify opportunities to increase the efficacy of metadata, and to improve efficiency of metadata generation processes in national and local services. Essentially it will investigate the trade-offs between "value to user" and "cost of creation" in order to establish the optimum point for value for money in metadata generation. In so doing this project will make more cost effective the delivery of scholarly resources for research and learning. Intute is uniquely placed to undertake this work because of the information held on the time and cost of manual metadata generation, the existence of the current Intute database of Internet resources for benchmarking purposes, and its unrivalled expertise in metadata creation and use. The outcomes of this project will be of enormous benefit to and stimulate change in the JISC community. Project start date: 2009-04-01. Project end date: 2010-09-01. (Excerpt from this source)

The Visual Resources Association (also known as VRA) is an international organization for image media professionals, VRA was founded in 1982 by slide librarians (visual resources curators) who were members of the College Art Association (CAA), the South Eastern Art Conference (SECAC), the Art Libraries Society of North America (ARLIS/NA), and the Mid-America College Art Association (MACAA). The association is concerned with creating, describing, and distributing digital images and other media; educating image professionals; and developing standards. The Visual Resources Association Foundation, a 501 C-3 organization created by the VRA, supports research and education in visual resources, and provides educational, literary, and scientific outreach to the archival and library community and the general public.

VT100 is a video terminal that was made by Digital Equipment Corporation (DEC). Its detailed attributes became the de facto standard for terminal emulators. It was introduced in August 1978, following its predecessor, the VT52, and communicated with its host system over serial lines using the ASCII character set and control sequences (a.k.a. escape sequences) standardized by ANSI. The VT100 was also the first Digital mass-market terminal to incorporate "graphic renditions" (blinking, bolding, reverse video, and underlining) as well as a selectable 80 or 132 column display.

The Shibboleth 'where are you from service' (WAYF) provides the user with a list of institutional identity providers (IdPs) and allows them to choose at which one they wish to authenticate. The WAYF then redirects the user to the chosen IdP. (Excerpt from this source)

Web Storage and DOM Storage (Document Object Model) are web application software methods and protocols used for storing data in a web browser. Web storage supports persistent data storage, similar to cookies, as well as window-local storage. Web storage is being standardized by the World Wide Web Consortium (W3C). It was originally part of the HTML 5 specification, but is now in a separate specification. It is supported by Internet Explorer 8, Mozilla-based browsers (e.g., Firefox 2+, officially from 3.5), Safari 4, Google Chrome 4 (sessionStorage is from 5), and Opera 10.50. As of 14 July 2010 only Opera supports the storage events (Excerpt from Wikipedia article: Web storage)

Web conferencing refers to a service that allows conferencing events to be shared with remote locations. Most vendors also provide either a recorded copy of an event, or a means for a subscriber to record an event. The service allows information to be shared simultaneously, across geographically dispersed locations in nearly real-time. Applications for web conferencing include meetings, training events, lectures, or short presentations from any computer. A participant can be either an individual person or a group. System requirements that allow individuals within a group to participate as individuals (e.g. when an audience participant asks a question) depend on the size of the group. Handling such requirements is often the responsibility of the group. In general, system requirements depend on the vendor. The service is made possible by Internet technologies, particularly on IP/TCP connections. (Excerpt from Wikipedia article: Web conferencing)

Wikimania is an annual international conference for users of the wiki projects operated by the Wikimedia Foundation (such as Wikipedia and other sister projects).
