Decoder Equipped

The technology that makes a videoconference (also known simply videoteleconference or VTC) is known as digital compression of audio and video stream time real. Videoconferencing software or hardware that causes compression to occur is called a codec (or sometimes called a coder / decoder). The achievement rates Compression is up to about 1:500.

The digital stream of ones and zeros that is the result of all this is broken down further into what is known as packages. These packages are navigating through a network of digital computers, if an IP or ISDN. Modems are used in audio transmission line, which makes full use of the network normal phone (abbreviated POTS) in a variety of low-speed applications, for example, video, converting the digital pulse / analog waves in the audio spectrum range.

Other items needed are the videoconference equipment video input consisting of a video camera or a webcam, video output that is a television or computer monitor, audio input, which is microphones, the audio output which often consists of speakers that have a strong association with either the phone or display device, and finally, the data transfer can be analog or digital telephone network, and both the Internet or LAN.

At one point the type of videoconferencing equipment is needed and how it is organized on a room depends on the person making use of equipment (and your skill level) and the context in which the videoconferencing system to use.

Videoconferencing equipment corresponds to one of the three types configurations. The team all must comply with the H.320 standards and these standards vary with the type of video that will be conducted and the size in terms of people and place, that the conference will be. The three types are room systems, roll-about units and the desktop.

Room systems are geared towards the video involves a large group of people, for example, a training session, a group interview, a discussion of a group meeting and so on. Room systems (sometimes referred to as dedicated systems) are often housed in specially designed rooms with video in mind. Usually contain a series of cameras and computer monitors.

Room systems are all-in-one and have all necessary pieces of equipment listed together in one place. These high-quality cameras remotely controlled video is known as PTZ cameras and can be manipulated in a number of different directions. The console holds part of the control computer, hardware or software-based codec and any and all electrical interfaces.

Attached to the console is known as microphones and omnidirectional microphones attached is a television monitor that comes with speakers and / or possibly include a video projector.

There are three types of dedicated (or room) and includes systems for large group, small group and individual conferencing. Videoconferencings large groups are large and can not be moved from their original location. Also this type are more expensive and tend to be used in auditoriums and large rooms. In small groups sometimes it's portable video conferencing, while others are not. They are smaller in size, cheaper in price and are smaller rooms for meeting capacity. Individual Videoconferencing is intended for individual users and are often portable. Built in the console are fixed cameras, speakers and microphones.

The form most common cause of videoconferencing equipment is deployed on the unit and such are best suited for small-sized conferences or smaller meetings ability of the group. The vote on the units are in a car that contains one or sometimes two computers, monitors, camera, codec and other essential equipment. The only drawback to the vote on the configuration of the unit is the lack of access to a network in a conference room in spite of this fact.

Desktop's systems are add-ons, such as hardware cards, for example, that enable a personal computer into a device used for video conferencing. A camera, microphone, software and tips are equipped for computer and this allows the video conferencing session to take place. The card contains the codec and interfaces transmission and a series of cameras and microphones can use for this purpose.

The computer can connect to a variety of different websites, but more appropriate one by one the types of conferences. This form of a video conference also known as a meeting mailing.
