Videoconferencing |
|
|
|
A videoconference or video conference (also known as a video teleconference) is a set of interactive telecommunication technologies which allow two or more locations to interact via two-way video and audio transmissions simultaneously. It has also been called 'visual collaboration' and is a type of groupware. Videoconferencing differs from videophone calls in that it's designed to serve a conference rather than individuals. It is an intermediate form of video telephony, first deployed commercially by AT&T during the early 1970s using their Picture phone technology. |

There was 3 guys stranded in the mountains and they weren't going to be rescued for 3 days.
So they all made a plan that each day one would get the food. So the first day the 1st guy goes out and comes back with a big deer.
So the guy who was hunting tomorrow ask for advice on how to catch another one, and the guy said see tracks, follow tracks.
So the next day the 2nd guy went out and came back with an even bigger deer than the 1st guys, and the 3rd guy was amazed so he asked how he could catch one like that for the next day.
And the guy told him see tracks, follow tracks.
The next night the 3rd guy went out to get a deer and comes back hours later all beat up and bloody, so the other 2 guys ask what happen.
And the guy said I seen tracks, followed tracks,
BAM!! Got hit by train.

A little old lady answered a knock on the door one day, only to be confronted by a well-dressed young man carrying a vacuum cleaner.
"Good morning," said the young man. "If I could take a couple of minutes of your time, I would like to demonstrate the very latest in high-powered vacuum cleaners."
"Go away!" said the old lady. "I haven't got any money!" and she proceeded to close the door.
Quick as a flash, the young man wedged his foot in the door and pushed it wide open. "Don't be too hasty!" he said. "Not until you have at least seen my demonstration."
And with that, he emptied a bucket of horse manure onto her hallway carpet.
"If this vacuum cleaner does not remove all traces of this horse manure from your carpet, Madam, I will personally clean the remainder."
"Well," she said, "I hope you've got a good appetite because the electricity was cut off this morning."

Blu-ray Disc (official acronym BD or BRD, colloquially also known as BR or Blu-ray) is an optical disc storage medium designed to supersede the standard DVD format. Its main uses are for storing high-definition video, PlayStation 3 video games, and other data, with up to 25 GB per single-layered, and 50 GB per dual-layered disc. Although these numbers represent the standard storage for Blu-ray Disc drives, the specification is open-ended, with the upper theoretical storage limit left unclear. 200 GB discs are available, and 100 GB discs are readable without extra equipment or modified firmware. The discs have the same physical dimensions as standard DVDs and CDs. The name Blu-ray Disc derives from the "blue laser" used to read the disc. While a standard DVD uses a 650 nanometer red laser, Blu-ray Disc uses a shorter wavelength 405 nm laser, and allows for almost ten times more data storage than a DVD. |

Knowledge Management (KM) |
|
|
Knowledge Management (KM) comprises of a range of strategies and practices used in an organization to identify, create, represent, distribute, and enable adoption of insights and experiences. Such insights and experiences comprise knowledge, either embodied in individuals or embedded in organizational processes or practice. Many large companies and non-profit organizations have resources dedicated to internal KM efforts, often as a part of their 'business strategy', 'information technology', or 'human resource management' departments.
Knowledge Management efforts typically focus on organizational objectives such as improved performance, competitive advantage, innovation, the sharing of lessons learned, integration and continuous improvement of the organization. KM efforts overlap with organizational learning, and may be distinguished from that by a greater focus on the management of knowledge as a strategic asset and a focus on encouraging the sharing of knowledge. KM efforts can help individuals and groups to share valuable organizational insights, |

Cherries: Apart from nutritional benefits of cherries, it has been discovered that cherries provide a number of healing benefits. Cherries are very perishable and do not ripen after harvest. They only remain fresh in the refrigerator for only a few days after harvest. The cherry fruit are low in fat, sodium, cholesterol and are a source of fiber and Vitamin A,C and E. Cherry products are available in cherry juice, canned cherries, cherry juice concentrate, fresh cherries, dried and frozen. Sweet as well as sour cherries can be used for jams. Sour cherries are used more often as an ingredient in pies and are suitable for making souffles, cooked fruit compotes etc. Cherries are very versatile fruits and can be a part of any meal or dessert. From breakfast to soups and salads, these find their way into any food item easily. |

Beets: Beets were an important plant for both the ancient Greeks and Romans. Red beets get their color from a pigment called "betalain." Betalain is also responsible for the red color of bougainvillea and amaranth. Sugar beets are about 20% sugar while beets or beetroot are usually no more than 10% sugar. Beets are sometimes used to make homemade wine. Beet offers invaluable nutritional benefits. Beet is the source for potassium, fiber and folate. While the sweet beet root has some of the minerals in its greens to a lesser degree, it is also a remarkable source of choline, folic acid, iodine, manganese, organic sodium, potassium, fiber and carbohydrates in the form of natural digestible sugars. |

Basketball: Basketball was invented by a rugby coach in1891 - Dr. James Naismith was looking for an indoor activity to provide winter conditioning for his rugby players. Rugby was an Olympic sport in 1900, 1908, 1920, and 1924. The US won the Gold Medal in 1920 and 1924. The world’s first international rugby game was played in 1871 between Scotland and England. Scotland won it, but England got their own back by winning at their next confrontation. This is an outdoor game played in a rectangular field of 100 m length and 70 metres width. At the end of the each side, goal posts of the letter "H" are placed. Rugby balls are shaped the way they are because the original balls, made by a cobbler near Rugby School, were fashioned from pigs’ bladders. These bladders naturally became oval-shaped when inflated – a grisly process which literally involved blowing into them like balloons. |

Venice: Venice is also known as "La Serenissima" (the most serenely beautiful one) and "Queen of the Adriatic". The city stretches across 117 small islands in the marshy Venetian Lagoon along the Adriatic Sea in northeast Italy. Venice has 160 canals connected by 409 bridges It is built on wood poles from Cadore forests, in the Alps. Venice is the only European city (and one of the few in the world) to have its public transport entirely on the water. The palaces in Venice were built with the facade in front of the canal. The entrance used today was actually the secondary one. The classical Venetian boat is the gondola, although it is now mostly used for tourists, or for weddings, funerals, or other ceremonies. St Mark’s Cathedral of Venice, also known as St Mark’s Basilica, is one of the most famous as well as most beautiful churches in the city. The historic city centre of Venice is divided into six quarters |
|
(sestieri) - Cannaregio, Castello, Dorsoduro, San Marco, San Polo and Santa Croce. Many famous people in history were born in Venice including Giacomo Casanova, the explorer Marco Polo, and composer Antonio Vivaldi. |

Videoconferencing |
| |
A videoconference or video conference (also known as a video teleconference) is a set of interactive telecommunication technologies which allow two or more locations to interact via two-way video and audio transmissions simultaneously. It has also been called 'visual collaboration' and is a type of groupware. Videoconferencing differs from videophone calls in that it's designed to serve a conference rather than individuals. It is an intermediate form of video telephony, first deployed commercially by AT&T during the early 1970s using their Picture phone technology. Videoconferencing uses telecommunications of audio and video to bring people at different sites together for a meeting. This can be as simple as a conversation between two people in private offices (point-to-point) or involve several sites (multi-point) with more than one person in large rooms at different sites. Besides the audio and visual transmission of meeting activities, videoconferencing can be used to share documents, computer-displayed information, and whiteboards. |
|
|
|
| Multipoint videoconferencing |
|
Simultaneous videoconferencing among three or more remote points is possible by means of a Multipoint Control Unit (MCU). This is a bridge that interconnects calls from several sources (in a similar way to the audio conference call). All parties call the MCU unit, or the MCU unit can also call the parties which are going to participate, in sequence. There are MCU bridges for IP and ISDN-based videoconferencing. There are MCUs which are pure software, and others which are a combination of hardware and software. An MCU is characterised according to the number of simultaneous calls it can handle, its ability to conduct transposing of data rates and protocols, and features such as Continuous Presence, in which multiple parties can be seen onscreen at once. MCUs can be stand-alone hardware devices, or they can be embedded into dedicated videoconferencing units. |
|
Some systems are capable of multipoint conferencing with no MCU, stand-alone, embedded or otherwise. These use a standards-based H.323 technique known as "decentralized multipoint", where each station in a multipoint call exchanges video and audio directly with the other stations with no central "manager" or other bottleneck. The advantages of this technique are that the video and audio will generally be of higher quality because they don't have to be relayed through a central point. Also, users can make ad-hoc multipoint calls without any concern for the availability or control of an MCU. This added convenience and quality comes at the expense of some increased network bandwidth, because every station must transmit to every other station directly. |
|
| Impact on the general public |
|
High speed Internet connectivity has become more widely available at a reasonable cost and the cost of video capture and display technology has decreased. Consequently, personal videoconferencing systems based on a webcam, personal computer system, software compression and broadband Internet connectivity have become affordable to the general public. Also, the hardware used for this technology has continued to improve in quality, and prices have dropped dramatically. The availability of freeware has made software based videoconferencing accessible to many. |
|
For many years, futurists have envisioned a future where telephone conversations will take place as actual face-to-face encounters with video as well as audio. Sometimes it is simply not possible or practical to have a face-to-face meeting with two or more people. Sometimes a telephone conversation or conference call is adequate. Other times, an email exchange is adequate. |
|
| Videoconferencing adds another possible alternative, and can be considered when: |
|
|
A Live conversation is needed |
|
|
Visual information is an important component of the conversation |
|
|
The parties of the conversation can't physically come to the same location; or |
|
|
The expense or time of travel is a consideration |
|
|
| Impact on education |
|
Videoconferencing provides students with the opportunity to learn by participating in a 2-way communication platform. Furthermore, teachers and lecturers from all over the world can be brought to classes in remote or otherwise isolated places. Students from diverse communities and backgrounds can come together to learn about one another. Students are able to explore, communicate, analyze and share information and ideas with one another. Through videoconferencing students can visit another part of the world to speak with others, visit a zoo, a museum and so on, to learn. These "virtual field trips" can bring opportunities to children, especially those in geographically isolated locations, or the economically disadvantaged. Small schools can use this technology to pool resources and teach courses (such as foreign languages) which could not otherwise be offered. |
|
| Here are a few examples of how videoconferencing can benefit people around campus: |
|
|
Faculty member keeps in touch with class while away for a week at a conference |
|
|
Guest lecturer brought into a class from another institution |
|
|
Researcher collaborates with colleagues at other institutions on a regular basis without loss of time due to travel |
|
|
Schools with multiple campuses can collaborate and share professors |
|
|
Faculty member participates in a thesis defense at another institution |
|
|
Administrators on tight schedules collaborate on a budget preparation from different parts of campus |
|
|
Faculty committee auditions a scholarship candidate |
|
|
Researcher answers questions about a grant proposal from an agency or review committee |
|
|
Student interviews with an employer in another city |

| Impact on medicine and health |
|
Videoconferencing is a very useful technology for telemedicine and telenursing applications, such as diagnosis, consulting, transmission of medical images, etc., in real time in countries where this is legal. Using videoconferencing, patients may contact nurses and physicians in emergency or routine situations, physicians and other paramedical professionals can discuss cases across large distances. Rural areas can use this technology for diagnostic purposes, thus saving lives and making more efficient use of health care money. For example, a rural medical center in Ohio, US, used video conferencing to successfully cut the number of transfers of sick infants to a hospital 70 miles away. Special peripherals such as microscopes fitted with digital cameras, video endoscopes, medical ultrasound imaging devices, otoscopes, etc., can be used in conjunction with videoconferencing equipment to transmit data about a patient. |
|
| Impact on business |
|
Videoconferencing can enable individuals in faraway places to have meetings on short notice. Time and money that used to be spent in traveling can be used to have short meetings. Technology such as VOIP can be used in conjunction with desktop videoconferencing to enable low-cost face-to-face business meetings without leaving the desk, especially for businesses with wide-spread offices. The technology is also used for telecommuting, in which employees work from home. Videoconferencing is now being introduced to online networking websites, in order to help businesses form profitable relationships quickly and efficiently without leaving their place of work. This has been leveraged by banks to connect busy banking professionals with customer in various locations using video banking technology. |
|
Although it already has proven its potential value, research has shown that many employees do not use the videoconference equipment because they are afraid that they will appear to be wasting time or looking for the easiest way if they use videoconferencing to enhance customer and supplier relationships. This anxiety can be avoided if managers use the technology in front of their employees. Researchers find that attendees of business and medical videoconferences must work harder to interpret information delivered during a conference than they would if they attended face-to-face. They recommend that those coordinating videoconferences make adjustments to procedures and equipment. |
|
| Videoconferencing Today |
|
The videoconferencing industry today is undergoing its most important transformation since the early 1980s. While room conferencing systems continue to provide improved audio and video quality and ever-more impressive features and functions at ever decreasing prices, the real action is going on at the desktop where multiple vendors with multiple strategies are vying for the enterprise user base. The proliferation of videoconferencing and personal collaboration tools is being driven by several technology trends: |
|
|
The deployment of more powerful personal computers able to handle multiple tasks while delivering outstanding audio and video quality. |
|
|
The deployment of IP, the current network of choice, to virtually every desktop. Enterprises today are moving toward IP-based voice, video, and data communications, providing a more reliable, easier to manage network infrastructure. |
|
|
The emergence of presence as a de facto communications tool, enabling enterprise workers to see not only the availability of their colleagues, but also their ability to participate in a text, voice, or video conference. Due to its ease of use and natural fit with ad-hoc, on-demand calling models, presence is quickly becoming the user interface of choice for many communications tools. |
|
|
The result is that while room videoconferencing continues to benefit from improved price/performance, personal conferencing continues to define new paradigms for enhancing enterprise productivity without interrupting employee workflow. |
|
Videoconferencing and collaboration are in the midst of a fundamental paradigm shift as new technologies, new vendors, and new partnerships bring integrated voice, video, and web solutions to the enterprise desktop. These personal tools enable knowledge workers to communicate anywhere, anytime, with local and remote colleagues, without leaving the comfort and efficiency of their work space. This speeds up decision making, boosts productivity, and contributes directly to the bottom line. Conferencing and collaboration solutions have finally joined the ranks of the telephone and email as core business tools that global enterprises need to compete in today’s global marketplace. |

Blu-ray Disc (official acronym BD or BRD, colloquially also known as BR or Blu-ray) is an optical disc storage medium designed to supersede the standard DVD format. Its main uses are for storing high-definition video, PlayStation 3 video games, and other data, with up to 25 GB per single-layered, and 50 GB per dual-layered disc. Although these numbers represent the standard storage for Blu-ray Disc drives, the specification is open-ended, with the upper theoretical storage limit left unclear. 200 GB discs are available, and 100 GB discs are readable without extra equipment or modified firmware. The discs have the same physical dimensions as standard DVDs and CDs. The name Blu-ray Disc derives from the "blue laser" used to read the disc. While a standard DVD uses a 650 nanometer red laser, Blu-ray Disc uses a shorter wavelength 405 nm laser, and allows for almost ten times more data storage than a DVD. While this laser color is called "blue," it is actually violet (purple) to the eye, and is very close to ultraviolet ("blacklight"). |
