As you enter the world of video teleconferencing, you will encounter a wealth of video and audio advancements that expands your communication capabilities.
Through this method of teleconference, two or more separate sites receive the ability to contact one another by way of enhanced visual and audio means. Of course, there are a variety of equipment requirements needed before you are able to communicate in this manner, but the journey is well worth the effort.
Through the transfer of video and audio, individuals located at various sites may come together for a meeting. Simple conversations can take place between two private office dwellers in what is known as point-to-point teleconferencing.
When more than two sites are involved, it is called a multi-point conversation. Through various software titles and desktop capabilities, this form of teleconferencing allows the sharing of documents, whiteboards, as well as computer displays of information.
The meat of the technology regarding video teleconferencing involves the compression of digital audio and video streams of real time data. This compression is made possible through what is called a codec, which stands for coder/decoder. Data is broken up into a series of 1’s and 0’s, which are transported across networks in the form of packets. The entire process deals with the compression, transmission, and delivery of information.
When setting up a videoconference system, you will encounter an array of components, which makes this process a reality. On the video side of things, video input, such as a video camera or webcam is needed. Video output is accomplished through a television, projector, or computer monitor.
Microphones supply the audio input, while loudspeakers are used to present audio output. As for the transfer of data, it depends on the type of telephone network you have, which could be analog or digital. LAN or Internet is also used to transmit information.
Depending on your intended use of a video teleconference (VTC) system, you may choose between a wide-range of systems. There are two main types of VTC offering a variety of service options.
Basically, a dedicated system relies on a console containing all of the required necessities for teleconferencing. A control computer, electrical interface, software and/or hardware are included. An example includes auditoriums outfitted with a sizable, non-portable, costly device for videoconferencing. There are also individual-use dedicated systems, which offer portable devices with all-in-one fixed cameras, microphones, and loudspeakers.
With desktop systems, upgrades and additional parts are introduced to a personal computer, which allows users to access VTC capabilities. This opens up the door to a wide-range of cameras and microphones that one may choose. Meetings that take place through these systems are often referred to as an e-meeting.
When choosing the type of services and equipment you may need to teleconference, you should take a look at what you will be using the gear, hardware and software for.
The Many Uses of Video Teleconferencing
If you are an individual sitting at home, wishing to contact family and friends through a video conference call, there are plenty of free software choices to consider. This type of software brings the ability to enjoy such an advanced mode of communication in an easy manner to the public. The general public has found it quite easy to create their own personal video teleconference systems by simply using a webcam, computer, broadband Internet, and applicable software.
Besides entertaining the home computer user, VTC has opened the lines of communication and learning in a wide spectrum of work fields. In the world of medicine, videoconferencing has assisted the increase of accurate and speedy diagnosis, consultations, as well as important medical image reviews. Whenever a doctor needs help with a particular case, the use of advanced audio and video communication allows he or she to easily retrieve additional opinions.
Educational circles have made strides through the use of VTC because of the infinite amount of virtual learning experiences. Smaller schools or economically starved districts may also bring foreign language courses and other online exploration to their students.
Two-way communication also helps student minds blossom, as they are able to share ideas and thoughts across the globe with others. Business employees find videoconferencing a real treat when it comes to conducting meetings on short notice. It also cuts down on the time, money and energy spent traveling to meet with clients. Through this type of technology, many employees are also able to telecommute and work from home.
Advantages and Disadvantages
Video teleconferencing is a technological wonder that presents both its fair share of advantages and disadvantages. The pros pertaining to VTC includes cost reductions, increased communication across all boards, flexibility, and advance scheduling. Employees are also able to participate in meetings on a regional, national, as well as worldwide level.
As for the disadvantages of VTC, the threat of technical failure always lingers. There are also interpersonal matters to consider, such as the effectiveness of negotiation or bargaining.
One must also learn the ropes regarding the equipment in order to participate, and the decrease in socialization and personalization sometimes hurts a business move. For most companies and individuals, the pluses far outweigh the minuses.
