Video conferencing assuredly encompasses a range of technologies used in a wide range of situations, often it is not just video and audio that is transmitted, but also data, allowing collaborative working though shared applications. All of this means having adequate bandwidth supporting your network is the indispensable operation factor.
Video conferencing may be?
* One-to-one meetings, also known as point to point communications, normally spicy full two-way audio and video.
* One-to-many spicy full audio and video broadcast from the main site, where other sites may be able to send audio. For example in a lecture situation, students could ask questions.
* Many-to-many, known as multi-point communication, provides audio and video in the middle of more than two sites. With most multi-point systems only one site in a discussion can be seen at time, with switching in the middle of sites whether controlled manually or voice activated (i.e., the loudest site is on screen).
Physically, the most coarse scenarios of video conferencing are:
* desktop video conferencing ? normally a small camera is located on top of the Pc or workstation monitor. The actual video is normally displayed in a small window, and shared applications, such as a shared whiteboard are often used.
* studio-based systems ? a studio is specially adequate for video conferencing. This will normally contain one or more cameras, microphones, one or more large monitors, and perhaps other tool such as an overhead camera for document viewing. normally used for more formal meetings
In custom a ?studio? may not be a dedicated room, but a standard discussion room with portable tool that can be set up when required.
Bandwidth and Compression?
The bandwidth, or baud rate, is the whole of facts which can be transmitted every second. The higher the bandwidth, the better quality the signal that can be transmitted. For a video discussion audio and video signals must be transmitted in real time, i.e., a lot of facts has to be sent every second, requiring a very high bandwidth. For example a ?true colour? image will need 24 bits (3 bytes) per pixel. A full screen image might be 640?480 pixels, over 7 million bits. For full petition video, the image is refreshed 25 times per second. This adds to over 184 million bits per second. It is not realistically possible to transmit this whole of information, and your Pc assuredly could not receive it at this rate. Therefore for digital video some form of compression is required. The type and degree of compression used varies from system to system. It is spicy to note that for most uses, we are more tolerant of poor video than poor audio, and so some systems merge on providing consistently good audio.
How To Get The Right Bandwidth To Meet Your Needs?
Don?t take a chance at guessing what bandwidth you?ll need?or in choosing the victualer for that bandwidth. You may need a fractional, full, integrated, or bonded T1, Ds3, or Oc3 network depending on many factors. Solutions offered by providers will vary by cost, quality of assistance (QoS), and assistance Level agreement (Sla). I strongly propose you use the services of an independent Telecommunications counselor to help you assess your needs and find the victualer who best meets your requirements. For unbiased free advice?.as well as real time rate quotes from multiple providers, indepth research, and negotiations with providers on your behalf?.I propose you use FreedomFire Communications.
