What is video conferencing?
Video conferencing is a communications technology that integrates audio and video by connecting remote users to each other over the Internet as they are in the same room. Everyone needs a computer, microphone, webcam, and broadband Internet to participate in videoconferencing. Users see and hear each other at both ends in real time, allowing natural conversation. Many communication companies depend on the technology of videoconferencing.
High-quality bandwidth is required for superior video conferencing. Video conferencing is becoming more popular with Microsoft Net meeting. Now there are a number of companies that support video conferencing software.
Video conferencing is very attractive for the education and business sector. Video conferencing has allowed users to approach (actually face to face) since they have saved the costs and time. Many universities have accepted videoconferencing as an educational tool. Business people worldwide use video conferencing to keep in touch with others.
Video conferencing is in a sophisticated phase and video conferencing applications and technologies are in the development and development process. Sometimes videoconferencing enables the creation of virtual cities and online places where people can work together without being physically present in the same concessions. Use a computer, video camera, and broadband Internet connection to create a videoconference connection.
Video conferencing is a very useful way to communicate, as it can save time on people's travel costs. Videoconferencing between two people is known as a point and is known as a multi-party conference. In addition to audio and video transmission between people, video conferencing can be used to share documents to share information that is displayed on a computer.
In the field of videoconferencing applications, further improvements can be achieved that people can work and manipulate at the same time in the same document and computer application. IEEE standards and guidelines for developing video conferencing. H.320 standard shows how video conferencing works on ISDN dial-up circuits. H.323 standard shows how video conferencing works on the Internet (TCP / IP or IP).
The quality of video conferencing depends on the characteristics of the circuit between the conference venues. In the H.323 world, the high-quality conference requires about 768Kb bandwidth. Universities and colleges have a higher bandwidth connection at 10Mbs.
Here are some rules for the bandwidth required by video conferencing.
768Kbs This camp is used and is of high quality.
384Kbs this bandwidth also provides good connectivity to IP and ISDN lines.
256Kbs Audio is OK but the video is incomplete.
128Kb audio and video are not excellent either.
If you have to choose between ISDN and IP for video conferencing, you have to consider two things for quality and cost. There is no additional cost without IP-based connections. On the other hand, despite the fact that there is some additional cost to the ISDN connection, but it provides constant speed and excellent connectivity quality, and there is no guaranteed bandwidth through the IP-based connection because of the commodity internet.
Video conferencing has several benefits. Here are the advantages of video conferencing technology.
· By using videoconferencing, members can remotely touch the classroom.
· Guest performances are available at another institution at a local level.
· Scientists and researchers can cooperate regularly in different institutions.
· Researchers and teachers can answer the agency's questions.
· In some countries, marriages are implemented using videoconferencing technology when one partner is at one end and the other is abroad. People can see each other at both ends.
· Student interviews with an employer working in another city or country.
Telework is now a name for a broader activity that includes individual interaction and collaboration between home entrepreneurs, consultants and business partners
Videoconference is also used in telemedicine.
Instructors of general, secondary and higher education and corporate trainers use videoconferencing. Video presentations become popular. There are also some applications that will automatically get remote visitors to the classroom and important performances. These offer great opportunities to value the use of the educational process as a videoconferencing tool.
A number of large companies have reduced their recruitment budgets and have conducted remote interviews through video conferencing, enabling them to display the right candidate.
