Getting the Right Bandwidth For Your Video Conferencing Applications

Video conferencing really encompasses a range of technologies employed in a wide selection of situations, typically it is not just video and audio that's transmitted, but also data, allowing collaborative working though shared applications. All of this implies having sufficient bandwidth supporting your network is that the vital performance factor.

Video conferencing may be...
* One-to-one meetings, additionally referred to as point to purpose communications, sometimes involving full 2-means audio and video.
* One-to-several involving full audio and video broadcast from the main site, where other sites might be able to send audio. For instance in a very lecture scenario, students could ask questions.

* Several-to-many, known as multi-purpose communication, provides audio and video between additional than two sites. With most multi-point systems only one site in a very conference can be seen at time, with switching between sites either controlled manually or voice activated (i.e., the loudest web site is on screen).

Physically, the foremost common eventualities of video conferencing are:
* desktop video conferencing - typically a small camera is located on high of the PC or workstation monitor. The particular video is typically displayed in a tiny window, and shared applications, like a shared whiteboard are typically used.

* studio-based mostly systems - a studio is specially equipped for video conferencing. This will normally embrace a number of cameras, microphones, a number of massive monitors, and possibly different equipment like an overhead camera for document viewing. Sometimes used for more formal conferences

In observe a 'studio' could not be a dedicated space, however a normal seminar space with transportable equipment which will be founded when required.

Bandwidth and Compression...
The bandwidth, or baud rate, is the quantity of data that will be transmitted every second. The higher the bandwidth, the better quality the signal which will be transmitted. For a video conference audio and video signals should be transmitted in real time, i.e., a lot of data must be sent every second, requiring a very high bandwidth. As an example a 'true color' image will need twenty four bits (three bytes) per pixel. A full screen image would possibly be 640x480 pixels, over 7 million bits. For full motion video, the image is refreshed twenty five times per second. This adds to over 184 million bits per second. It's not realistically possible to transmit this amount of knowledge, and your PC actually may not receive it at this rate. Thus for digital video some kind of compression is required. The kind and degree of compression used varies from system to system. It's interesting to notice that for most uses, we have a tendency to are more tolerant of poor video than poor audio, and so some systems concentrate on providing consistently sensible audio.

How To Get The Right Bandwidth To Meet Your Needs...
Don't take a likelihood at guessing what bandwidth you'll need...or in selecting the provider for that bandwidth. You will want a fractional, full, integrated, or bonded T1, DS3, or OC3 network relying on several factors. Solutions offered by providers will vary by cost, Quality of Service (QoS), and Service Level Agreement (SLA). I strongly suggest you employ the services of an independant Telecommunications Consultant to help you assess your desires and notice the supplier who best meets your requirements. For unbiased free advice....in addition to real time rate quotes from multiple providers, indepth research, and negotiations with suppliers on your behalf....I recommend you use FreedomFire Communications.
