The Basics Of Video Conferencing - Video Conferencing _____________________________________________________________________________________ By Taylor – http://www.iwowweservice.com/ Modern business operations all share the same rapidly depleting commodity: Time. When time is leveraged, productivity and output invariably increases within a business organization, VideoConferencing Technology continues to provide workers and businesses with new tools to help leverage time. Video conferencing could prove to be one of the most important time leveraging business tools of the 21st century.Once a luxury for only the largest companies, video conferencing is beginning to change the landscape of how businesses communicate with both employees and clients. In its simplest form, video conferencing allows two individuals to be thousands of miles apart yet still effectively communicate as if they were in the same room. Systems in use today can now connect multiple parties across multiple continents - in real time with excellent and high quality video and audio.The Origins of Video ConferencingVideo conferencing capabilities originated in the 1970s. Similar to every other technology in use today, video conferencing has changed dramatically since first being developed. Early proponents of video conferencing technology had no standards or protocols to rely on. This fact made a teleconference via video an expensive proposition - one that only huge companies and government agencies could afford. In a time where cell phones were still a decade away for most consumers and businesses, video teleconferences were few and far between Today, affordable networks and systems are widely available across the globe. Interoperability of video teleconferencing systems is virtually guaranteed now that standards and protocols have been clearly established.Specific Standards and Protocols for Video ConferencingTo make any technology usable for the masses, standards and protocols are required to insure systems, software and hardware are ubiquitous across the board.To help guarantee video teleconferencing compatibility between manufacturers, the International Telecommunications Union developed and defined a series of video conferencing standards. In place since the mid-1990s, current standards are defined in terms "umbrella" recommendations for video conferencing. They include the protocols for coding video/audio, multiplexing, signaling, and control.Narrow-band video conferencing over circuit-switched networks (N-ISDN, SW56, dedicated networks) H.321 - Narrow-band video conferencing over ATM and B-ISDN H.323 - Narrow-band video conferencing over non-guaranteed quality-of-service packet networks (LAN, Internet, etc.) . narrow-band video conferencing over the general (dial-up) telephone network H.310 - Wide-band (MPEG-2) video conferencing over ATM and B-ISDN H.323 is a standard for audio, video, and data communication over IP-based (Internet Protocol) networks.All major video conferencing manufacturers produce ITU compliant equipment. When choosing video conference equipment, be sure that you select a system that does not offer only proprietary methods of operation. How Video Conferencing WorksThe success of a video teleconference depends entirely on the equipment and network capabilities behind that equipment.Since real-time video contains a tremendous amount of data, it is imperative that the system being used can handle a high amount of bandwidth at any given time. Fortunately, video conferencing systems are designed to "sample" and "compress" a certain portion of data (such as the unchanging "background' of the room) to help conserve bandwidth. This compression is accomplished through what is commonly known as a "codec". A video codec is the device or software that enables video compression and or decompression for digital video.It is the job of the codec to "sample" data at specific time intervals (fractions of a second) and then compress this data so that it can be delivered across the network. The codec on the receiving end then reassembles audio and video for transmission onto a television or computer screen. To conserve bandwidth, the codec focuses on the most important data - i.e. moving objects such as people, props, etc. Moving objects take a considerable amount of processing power, so the better the codec, the higher quality your video conference will appear.
