Do you know about - The History of Video Conferencing - enthralling Ahead at the Speed of Video
Voice Conference Call! Again, for I know. Ready to share new things that are useful. You and your friends.No new technology develops smoothly, and video conferencing had more than its share of bumps along the way before becoming the widely used communications staple it is today. The history of video conferencing in its earliest form goes back to the 1960's, when At&T introduced the Picturephone at the World's Fair in New York. While viewed as a inviting curiosity, it never became beloved and was too high-priced to be practical for most consumers when it was offered for 0 a month in 1970. commercial use of real video conferencing was first realized with Ericsson's demonstration of the first trans-Atlantic Lme video telephone call. Soon other companies began refining video conferencing technologies, including such advancements as network video protocol (Nvp) in 1976 and packet video protocol (Pvp) in 1981. None of these were put into commercial use, however, and stayed in the laboratory or inexpressive business use. In 1976, Nippon Telegraph and Telephone established video conferencing (Vc) between Tokyo and Osaka for business use. Ibm Japan followed suit in 1982 by establishing Vc running at 48000bps to link up with already established internal Ibm video conferencing links in the United States so that they could have weekly meetings. The 1980's introduce commercial video conferencing In 1982, Compression Labs introduces their Vc theory to the world for 0,000 with lines for ,000 an hour. The theory was huge and used immense resources capable of tripping 15 amp circuit breakers. It was, however, the only working Vc theory available until PictureTel's Vc hit the store in 1986 with their substantially cheaper ,000 theory with 0 per hour lines. In the time in between these two commercially offered systems, there were other video conferencing systems advanced that were never offered commercially. The history of video conferencing isn't perfect without mentioning these systems that were whether prototypes or systems advanced specifically for in-house use by a collection of corporations or organizations, including the military. Colse to 1984, Datapoint was using the Datapoint Minx theory on their Texas campus, and had provided the theory to the military. In the late 1980's, Mitsubishi began selling a still-picture phone that was basically a flop in the store place. They dropped the line two years after introducing it. In 1991, the first Pc based video conferencing theory was introduced by Ibm - PicTel. It was a black and white theory using what was at the time an incredibly inexpensive per hour for the lines, while the theory itself was ,000. In June of the same year, Dartnet had successfully associated a transcontinental Ip network of over a dozen investigate sites in the United States and Great Britain using T1 trunks. Today, Dartnet has evolved into the Cairn system, which connects dozens of institutions. Cu-SeeMe revolutionizes video conferencing One of the most illustrious systems in the history of video conferencing was the Cu-SeeMe advanced for the MacIntosh theory in 1992. Although the first version didn't have audio, it was the best video theory advanced to that point. By 1993, the Mac agenda had multipoint capability, and in 1994, Cu-SeeMe Mac was true video conferencing with audio. Recognizing the limitations of Mac compatibility in a Windows world, developers worked diligently to roll out the April 1994 Cu-SeeMe for Windows (no audio), followed closely by the audio version, Cu-SeeMe v0.66b1 for Windows in August of 1995. In 1992, At&T rolled out their own ,500 video phone for the home market. It was a borderline success. That same year, the world's first Mbone audio/video broadcast took place and in July Inria's video conferencing theory was introduced. This is the year that saw the first real explosion in video conferencing for businesses Colse to the globe and finally led to the standards advanced by the Itu. International Telecommunications Union develops coding standards The International Telecommunications Union (Itu) began developing standards for video conferencing coding in 1996, when they established accepted H.263 to cut bandwidth for transmission for low bit rate communication. Other standards were developed, including H.323 for packet-based multi-media communications. These are a collection of other telecommunications standards were revised and updated in 1998. In 1999, accepted Mpeg-4 was advanced by the inviting picture Experts Group as an Iso accepted for multimedia content. In 1993, VocalChat Novell Ipx networks introduced their video conferencing system, but it was doomed from the start and didn't last. Microsoft finally came on board the video conferencing bandwagon with NetMeeting, a descendent of PictureTel's Liveshare Plus, in August of 1996 (although it didn't have video in this release). By December of the same year, Microsoft NetMeeting v2.0b2 with video had been released. That same month, VocalTec's Internet Phone v4.0 for Windows was introduced. Vrvs links global investigate centers The Virtual Room Videoconferencing theory (Vrvs) task at Caltech-Cern kicked off in July of 1997. They advanced the Vrvs specifically to contribute video conferencing to researchers on the Large Hadron Collider task and scientists in the High power and Nuclear Physics community in the U.S. And Europe. It has been so victorious that seed money has been allotted for phase two, CalRen-2, to heighten and develop on the already in-place Vrvs theory in order to develop it to encompass geneticists, doctors, and a host of other scientists in the video conferencing network Colse to the world. Cornell University's improvement team released Cu-SeeMe v1.0 in 1998. This color video version was compatible with both Windows and MacIntosh, and huge step forward in pc video conferencing. By May of that year, the team has moved on to other projects. In February of 1999, Session Initiation Protocol (Sip) was launched by Mmusic. The platform showed some advantages over H.323 that user appreciated and soon made it almost as popular. 1999 was a very busy year, with NetMeeting v3.0b arrival out, followed fast by version three of the Itu accepted H.323. Then came the release of iVisit v2.3b5 for both Windows and Mac, followed by Media Gateway operate Protocol (Mgcp), version 1. In December, Microsoft released a aid pack for NetMeeting v3.01 (4.4.3388) and an Iso accepted Mpeg-4 version two was released. Finally, Psinet was the first business to begin H.323 self-operating multipoint services. Like we said, 1999 was a very busy year. Sip entered version 1.30 in November of 2000, the same year that accepted H.323 hit version 4, and Samsung released their Mpeg-4 streaming 3G video cell phone, the first of its kind. It was a hit, particularly in Japan. Rather predictably, Microsoft NetMeeting had to release an additional one aid pack for version 3.01. In 2001, Windows Xp messenger announced that it would now retain Session Initiation Protocol. This was the same year the world's first transatlantic tele-surgery took place utilizing video conferencing. In this instance, video conferencing was instrumental in allowing a surgeon in the U.S. To use a robot overseas to achieve gall bladder surgery on a patient. It was one of the most compelling non-business uses in the history of video conferencing, and brought the technology to the attentiveness of the curative profession and the general public. In October of 2001, television reporters began using a conveyable satellite and a videophone to broadcast live from Afghanistan during the war. It was the first use of video conferencing technology to converse live with video with man in a war zone, again bringing video conferencing to the forefront of people's imaginations. Founded in December of 2001, the Joint Video Team completed basic investigate foremost to Itu-T H.264 by December of 2002. This protocol standardized video compression technology for both Mpeg-4 and Itu-T over a broad range of application areas, production it more versatile than its predecessors. In March of 2003, the new technology was ready for begin to the industry. New uses for video conferencing technologies 2003 also saw the rise in use of video conferencing for off-campus classrooms. Interactive classrooms became more beloved as the ability of streaming video increased and the delay decreased. companies such as Vbrick provided discrete Mpeg-4 systems to colleges across the country. Desktop video conferencing is also on the rise and gaining popularity. companies newer to the store are now refining the details of carrying out in addition to the nuts and bolts of transmission. In April of 2004, Applied Global Technologies advanced a voice-activated camera for use in video conferencing that tracks the voice of discrete speakers in order to focus on whoever is speaking during a seminar call. In March 2004, Linux announced the release of GnomeMeeting, an H.323 compliant, free video conferencing platform that is NetMeeting compatible. With the constant advances in video conferencing systems, it seems determined that the technology will continue to evolve and become an integral part of business and personal life. As new advances are made and systems become more reasonably priced, keep in mind that choices are still considered by network type, theory requirements and what your singular conferencing needs are.
