A video conference is a friendly interaction through devices, which allow two or more people in different places to communicate remotely simultaneously. Also called a video meeting or remote audio video meeting. It is different from a videophone because the technology is focused on the conference, not the individual.
The most primitive type of video conferencing equipment is television. Although the transmission of information was one way, there is feedback after the transmission. The information cycle and the feedback process is fulfilled by the television that qualifies it as video conferencing equipment.
From the development of Internet-based and digital telephony services as software, such as NetMeeting, MSN Messenger, Yahoo Messenger and other instant messaging web plugins that allow the transmission of messages in real time over the Internet. The Internet has become the most important tool for video conferencing and other instant messaging services.
Due to the high speed of the Internet within itself and the ability to transfer information in real time, most web-based video conferencing centers put most of their resources online.
Due to the advancement of Internet technology, over the years it has been possible to have simultaneous videoconferences between three or more remote points. These remote points can be anywhere in the world and remote locations do not need to have a special set of equipment or software.
However, there is a bridge that connects all these remote peripherals to the network and called MCU or multichannel unit, it allows different computers to run the same format code to communicate on a network.
There are MCU bridges for IP and ISDN based video conferencing. The MCUs used as bridges in IP and ISDN connections are, most of the time, pure software, and others that can be found in other forms of connections are a combination of hardware and software.
The type of an MCU is determined according to the number of simultaneous calls and conference participants it can handle, its ability to conduct information exchanges, shared programs, shared documents, shared applications, and other different types of sharing peripherals available on The conference. One god thing about MCUs is that it can be a complete, standalone conference software as it doesn’t need hardware acceleration because it is purely software accelerated.
Due to the needs and the technology available to meet those needs, video conferencing has been more than a necessity for education, medicine, law making, and business.
For education, the impact of video conferencing on him and the system can be easily seen. Because high-speed Internet connection is becoming a much-needed part of the modern curriculum, video conferencing has also been part of the next step toward modernizing the school system. Thanks to video conferencing, special lecturers can now conference remotely, teachers can be on site and continue teaching the lesson, and correspondence between schools can be easily done via video conferencing.
Video conferencing classes also add to the possibility of a conversation on stage, as for example, a live conversation is needed between people from different countries. A visual information is an important component of the telephone conversation, the parts of the conversation cannot physically reach the same place.
Travel expense or time is a consideration because these situations require something drastically fast and efficient.
