Video Conferencing

Video conferencingVideo conferencing eliminates the need for travel to meetings, helping your business to make significant financial savings, increase key worker productivity and improve the speed and efficiency of your communications.

Modern businesses are increasingly aware of the impact their activities have on the environment and the need to minimise their ‘carbon footprint’. By reducing unnecessary travel, video conferencing can enable you to make a positive contribution to the environment without sacrificing productivity.

The latest video conferencing solutions deliver data-sharing capability, crystal-clear audio and exceptional video quality. They can bring together up to six locations simultaneously, satisfying even the most complex of scenarios. With the flexibility of communication via Internet Protocol over a LAN (local area network), the need for costly ISDN line installation and call charges can be eliminated.

Three brands of video conferencing system currently dominate the market: Polycom, Tandberg and Lifesize. Rockport Presentations can help you choose the system that best suits your needs and budget.

How does video conferencing work?

Video conferencing technology merges live audio and video signals and transmits them over telephone lines or the internet, enabling people at two or more locations to come together for a ‘real-time' meeting. As well as audio and video transmission, video conferencing incorporates dual-stream support for sharing documents, computer information and multimedia content.

Video conferencing systems utilise a codec at each end point. A codec compresses audio and video signals for transmission at the sending end, then uncompresses them at the receiving end. The codec, together with flat screen displays, cameras, microphones, echo-cancellers, mixers or equalisers, form the main components of a video conferencing system.

Video conferencing systems have standardised various communication protocols, including H.239 (a streaming standard), H.263 (a video codec standard), H.264 (a video compression standard also known as MPEG-4 AVC) and H.323 (a multimedia communications standard for ISDN, PSTN and IP networks). Video conferencing over IP (VCoIP) enables global, simultaneous digital transmissions and is rapidly replacing ISDN technology used over traditional PSTN networks. Most video conferencing equipment will support IP to ISDN connectivity.

High definition video conferencing is changing the way people interact, bringing about a new era of higher quality face-to-face video communications. High definition video resolution (1280 x 720 pixels at 30 frames per second) gives participants a ‘true to size’ appearance, creating a more lifelike experience.

Telepresence is the ultimate 'state of the art' video conferencing solution. The telepresence system creates a realistic meeting experience, enabling participants to attend a meeting being held miles or even continents away and feel as if they are joining in across the table.
