Video Conferencing is a set of interactive sessions, which can be conducted between two or more people in different locations. With Video Conferencing, it is possible for two or more locations to communicate with one another by means of two-way communication. In a Video Conference, all the participants have their own screens and are connected to the same Video Conferencing System. Thus, a user in the Video Conference can interact with two or more people in real-time, via an internet connection, by means of a webcam or other video-related device, without having to move from his present position.
The heart of any video conferencing system usually consists of various components that allow the transfer and capture of video signals and audio streams. These components are Video output terminals or VODs; Video input terminals or audio input devices; Video display consoles or plasma screen displays; Computer software needed for the Conduct of the conference; and Internet connections. These components may also have additional functions, depending on the nature and use of the conference. These may include automatic redirection of the user's movements on the screens, for example, towards the target audience, or to another location where the presenter is, or the provision of security features such as allowing only specific computers to be used in the conference room, among others.
In a Video Conferencing System, the computer software needed for the coference can be downloaded onto the computers of all the participants, or the individual users can install the software onto their own computers. Once the software is installed, the individual participants need only to connect to each other through their computers. They can use their Video Conferencing Systems to participate in the conferences. The connection can be established through an IP PBX System via the Internet or through wireless means such as Bluetooth or USB cables. It is important, however, that each participant must have an adequate camera or display for properly viewing each other, as well as a microphone so that they may hear one another clearly. The microphone must be within reasonable hearing distance from each participant, and the cameras should preferably have automatic night vision capabilities so that the participants can see one another during the night.
One of the primary uses of a video conferencing system is the transfer of data. Data can either be transmitted through video signals or by audio signals. Data transmission over audio channels is referred to as radio frequency (RF) data transfer, while data transfer over video channels is known as laser data transfer. Some of the methods used to transfer data include the use of the Global Standard of Organization (GSM) and Digital Subscriber Line (DSL) technologies, which are the most common international standards for data transfer. Video conference services can also transfer video images.
Logitech Video Conferencing, has provided many organizations with a way to reduce the costs of travel and meeting expenses while still maintaining ongoing productivity. In fact, many organizations find that the savings obtained by using video conferencing systems allow them to conduct meetings even when there is no room in their offices to accommodate large groups of people. With this in mind, many companies find it beneficial to hold meetings in rooms that are not always fully occupied by staff members. By using a room-based video conferencing system, meetings can be held virtually anywhere--even on company holidays and vacations, when employees are not usually in the office.
In order to participate in a video conferencing system, you will need a computer, a microphone, a TV for side-view and audio input, and a broadband internet connection. The computer and microphone are using to view the person with whom you are communicating, and the TV provides audio input and output. You can view the other participants as well as the physical location of everyone in the room through a remote desktop connection. Because the system combines the benefits of a web camera and audio network, you may also use text chat or e-mail instead of video communications. When using a traditional analog video image source such as a television, the audio is usually processed first, before the video is transmitted to the appropriate display device.
