A video conference is a type of interaction through devices, which allows two or more people in different places to communicate remotely and simultaneously. Also called video meeting or remote audio-video meeting. It is different from a videophone because the technology focuses on the conference, not the individual.
The most primitive type of video conferencing equipment is the 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 videoconferencing equipment.
Since the development of digital telephony and Internet-based services such as software, such as NetMeeting, MSN Messenger, Yahoo Messenger, and other instant messaging web plugins that allow real-time transmission of messages over the Internet. The Internet has become the most important tool for video conferences and other instant messaging services.
Due to the high speed of the Internet and the ability to transfer information in real time, most web-based video conferencing centers put the majority of their resources online.
Due to the advancement of Internet technology, over the years it has been possible to have simultaneous video conferences between three or more remote points. These remote points can be anywhere in the world and the 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 it is called the MCU or Multi Channel Unit, it allows different computers running the same format code to communicate on a network.
There are MCU bridges for IP and ISDN-based video conferences. The MCUs that are used as bridges in IP and ISDN connections are in most cases pure software, and others that can be found in other forms of connection are a combination of hardware and software.
The type of an MCU is determined by the number of simultaneous calls and conference participants it can handle, its ability to perform information exchanges, shared programs, shared documents, shared applications, and various other types of shared peripherals available in the MCU. conference. One good thing about MCU is that it can be a complete conferencing standalone software as it doesn’t need hardware acceleration because it is purely software accelerated.
Because of the needs and the technology available to meet those needs, video conferencing has been more than a necessity for education, medicine, law, and business.
For education, the impact of video conferencing and the system can be easily seen. With high-speed Internet connection becoming a much-needed part of the modern curriculum, video conferencing has also been part of the next step toward modernizing the school system. Due to video conferencing, special teachers can now hold conferences remotely, teachers can be on site and still deliver the lesson, and correspondence between schools can be easily done through video conferencing.
Video conferencing classes also add to the possibility of a conversation on the stages, since a live conversation between people in different countries is needed. Visual information is an important component of the telephone conversation, the parties to the conversation cannot physically arrive at the same place.
The expense or travel time is a consideration because these situations require something drastically fast and efficient.
