Web Conferencing

Setup and install Web Conferencing software and devices along with providing tutorials and support on how to use it.

Video Conferencing or Web Conferencing is the conduct of a conference by a set of communication technologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions. It has also been called 'visual collaboration' and is a type of groupware. Collaboration, in this case, refers to the ability of workers in a company to work together simultaneously on a particular task. In the past, collaboration would have to be completed face to face. However, collaboration has become more complex, with the need to work with people all over the world in real time on a variety of different types of documents, using different devices.

With the introduction of relatively low cost, high capacity broadband telecommunication services in the late 1990s, coupled with powerful computing processors and video compression techniques, video conferencing usage has made significant inroads in business, education, medicine and media. Like all long distance communications technologies, by reducing the need to travel to bring people together the technology also contributes to reductions in carbon emissions, thereby helping to reduce global warming.

HD Video Conferencing

High definition video conferencing for desktops and multipurpose conference rooms does not require a large capital outlay or dedicated telepresence studio. All you need is an HD-capable webcam (720p) or standard HD pan-tilt-zoom camera, and a computer. In business-to-business video conferencing, HD is a core component of high-end telepresence offerings. It is also finding its way into traditional boardroom systems, and available in desktop software and online services too.

For most suppliers of video conferencing equipment, high definition requires a platform that is capable of encoding and decoding the HD video conferencing stream. Vendors such as Polycom developed a new line of codecs with greater processing power in order to support HD.

What is HD?

In the context of business-to-business (B2B) video conferencing, the term HD generally refers to 720p or better. In boardroom systems, the audio component is often vague since most of the time only human voice is relevant, unlike consumer applications where sound and music are obviously very important in movies and broadcast TV.It is a variation of the term high definition television, also referred to as HDTV. Current HDTV standards are defined by the International Telecommunication Union (ITU) in terms of screen resolution, frame rate, and audio format.

Technical definition: The current standard is 720 progressive scan lines (720p) at 60 frames per second, or 1080 interlaced encoding (1080i) at 50 fields (25 frames) per second, and 16:9 aspect ratio. The current audio format is Dolby Digital AC-3, also known as v5.1. Standards evolve and the ITU is already laying the groundwork for even higher quality 1080p50 and 1080p60. In the consumer world, HD refers to video cameras, broadcasts, televisions and so on that meet these ITU specifications. Or more loosely to anything — cinematic film, movies, trailers, shorts, streaming media, Windows media and photographs — capable of such sharp display or better.

HD Computers and Monitors - Most desktops are already at high definition standards or better. PC monitors at WXGA (1280 x 800) and SXGA (1280x1024) already exceed HD 720p specifications; and WUXGA (1290x1200) or better monitors are a superset of HD 1080i in both horizontal and vertical dimensions.

Transmission Quality - Today, virtually all business video communication is digital via TCP/IP-based networks and the public Internet. The only major variables are connection quality and whether or not Internet access goes over a shared or dedicated route, usually DS-3 (44 mbits/second) or better.

Cloud Computing & Superior Low-Latency Performance - However, the use of a cloud computing architecture gives users a distinct, low-latency transmission performance advantage over fixed-site, dedicated hardware solutions. By using a massive network of distributed computers to minimize latency while delivering all the benefits of load-balancing, failover, and the scalability that true cloud architecture provides, this ensures the highest quality video conferencing experience.

HD Video Capture - Another dynamic in the conferencing industry is the movement toward PC-based peripherals. Stand-alone audio/visual systems are increasingly becoming available as peripheral devices for modern PCs. Whether USB or PCI bus, so as long as new peripherals have device drivers, software vendors an use these new components via standardized APIs and leverage their availability, low-cost and consumer-driven HD quality.
