PictureTel Corp.
PictureTel Corporation, often shortened to PictureTel Corp., was one of the first commercial videoconferencing product companies. It achieved peak revenues of over $490 million in 1996 and 1997 and was eventually acquired by Polycom in October 2001. History PictureTel was founded in August 1984 as PicTel by MIT students Brian L Hinman, Jeffrey G. Bernstein and MIT Professor David H. Staelin. The team was also assisted initially by MIT Professor Michael Dertouzos and two of his grad students Greg Papadopoulos and Richard Soley. While at MIT Hinman and Bernstein were motivated by the video compression work by UC Davis Professor Anil K. Jain (1946–1988) and his colleague Jaswani R. Jain who published an important research paper combining block-based motion compensation and transform coding in December 1981. The result was PictureTel, creating one of the first real-time systems to implement motion compensation and transform coding in July 1986. PictureTel was funded as "PicT ...

David H
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, D ...

Bonding Protocol
Bonding protocol (short for "Bandwidth On Demand Interoperability Group") is a generic name for a method of bonding or aggregation of multiple physical links to form a single logical link. Bonding is the term often used in Linux implementations: on Windows based systems the term teaming is often used, and between network-devices we talk about link aggregation, LAG and Link Aggregation Control Protocol. Major categories * Asynchronous bonding protocol * Synchronous bonding protocol See also * Channel bonding * Inverse multiplexer * Link aggregation In computer networking, link aggregation is the combining ( aggregating) of multiple network connections in parallel by any of several methods, in order to increase throughput beyond what a single connection could sustain, to provide redundan ...

Ascend Communications
Ascend Communications was an Alameda, California-based manufacturer of communications equipment that was later purchased by Lucent Technologies in 1999. Ascend Communications was founded in 1988 and taken public in 1994. Initial investors included Kleiner, Perkins, Caulfield and Byers (KPCB); Greylock Partners; and New Enterprise Associates (NEA). Ascend Communications designed and manufactured equipment for high-density dialup installations, most notably the ''MAX TNT'', which allowed for a DS3 of dialup lines to be terminated in a few rack units. Customers such as AOL, Earthlink, Demon Internet, and UUnet purchased over two million dialup ports worth of ''MAX TNT'' access servers during the dialup days of the internet. Many companies still use ''MAX TNT'' for dialup (look for ''TNT'' in dialup hostnames). In the mid-1990s, the company was one of the leading vendors of ISDN modems and concentrators. Ascend Communications also acquired several companies. In 1996, it acquired ...

Video Compression
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding; encoding done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a sign ...

Initial Public Offering
An initial public offering (IPO) or stock launch is a public offering in which shares of a company are sold to institutional investors and usually also to retail (individual) investors. An IPO is typically underwritten by one or more investment banks, who also arrange for the shares to be listed on one or more stock exchanges. Through this process, colloquially known as ''floating'', or ''going public'', a privately held company is transformed into a public company. Initial public offerings can be used to raise new equity capital for companies, to monetize the investments of private shareholders such as company founders or private equity investors, and to enable easy trading of existing holdings or future capital raising by becoming publicly traded. After the IPO, shares are traded freely in the open market at what is known as the free float. Stock exchanges stipulate a minimum free float both in absolute terms (the total value as determined by the share price multiplied b ...

Telepresence
Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance or effect of being present via telerobotics, at a place other than their true location. Telepresence requires that the users' senses interact with specific stimuli in order to provide the feeling of being in that other location. Additionally, users may be given the ability to affect the remote location. In this case, the user's position, movements, actions, voice, etc. may be sensed to transmit and duplicate in the remote location to bring about this effect. Therefore information may be traveling in both directions between the user and the remote location. A popular application is found in telepresence videoconferencing, the highest possible level of videotelephony. Telepresence via video deploys greater technical sophistication and improved fidelity of both sight and sound than in traditional videoconferencing. Technical advancements in mobile collaboration ...

Michael Dertouzos
Michael Leonidas Dertouzos ( el, Μιχαήλ Λεωνίδας Δερτούζος; November 5, 1936 – August 27, 2001) was a professor in the department of Electrical Engineering and Computer Science at the Massachusetts Institute of Technology (MIT) and Director of the MIT Laboratory for Computer Science (LCS) from 1974 to 2001. Dertouzos predicted the expansion of computer use very early, and was one of the pioneers in many areas of technology. These included his contributions to the Web particularly through his visionary approach to ubiquitous computing. Early life Dertouzos was born in Athens, Greece. His father was an admiral in the Greek navy and the young Dertouzos often accompanied him aboard destroyers and submarines. This experience cultivated his interest in technology so that he learned Morse code, shipboard machinery, and mathematics at an early age. When he was 16, he came across Claude Shannon's work on information theory and MIT's attempt to build a mechanical ...
