PictureTel
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 "PicTe ...

Videotelephony
Videotelephony, also known as videoconferencing and video teleconferencing, is the two-way or multipoint reception and transmission of audio and video signals by people in different locations for real time communication.McGraw-Hill Concise Encyclopedia of EngineeringVideotelephony McGraw-Hill, 2002. Retrieved from the FreeDictionary.com website, January 9, 2010 A videophone is a telephone with a video camera and video display, capable of simultaneous video and audio communication. Videoconferencing implies the use of this technology for a group or organizational meeting rather than for individuals, in a videoconference.Mulbach et al, 1995. pg. 291. Telepresence may refer either to a high-quality videotelephony system (where the goal is to create the illusion that remote participants are in the same room) or to meetup technology, which can go beyond video into robotics (such as moving around the room or physically manipulating objects).

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 signal. C ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Kings of Israel and Judah, third king of the Kingdom of Israel (united monarchy), United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and Lyre, 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 David and Jonathan, a notably close friendship with Jonathan (1 Samuel), 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 Philistin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
