Video Teleconferencing: An Evolving Enterprise Necessity
Among all the Next-Big-Thing babbling you overhear at Internet conferences and workshops, rarely does the topic of video teleconferencing, or VTC as it is known, strike your eardrums. Part of the reason is the virtual transition stage we inhabit of voice over IP, where the mantra echoes: audio, audio, audio.

Among all the Next-Big-Thing babbling you overhear at Internet conferences and workshops, rarely does the topic of video teleconferencing, or VTC as it is known, strike your eardrums. Part of the reason is the virtual transition stage we inhabit of voice over IP, where the mantra echoes: audio, audio, audio.
Yet ask a marketing maven like S. Ann Earon, president of Telemanagement Resources International Inc., Skillman, N.J., about the prospects for VTC, and she replies, "VTC will become so big, it will make a fashion statement. People will only care what you wear above the waist."
For Earon, it is only a matter of time before VTC, in one format or another, will be everywhere, to the point of being an enterprise necessity. Sparking yet another business paradigm shift, she said, will be time constraints, distances and work loads.
"With the increase in penetration of network connectivity, along with so-called bandwidth on demand, people will no longer ask if you have VTC. They will simply ask for your video number and dial it," Earon said. "But it will be an evolutionary process."
Evidence of VTC's popularity now comes through disasters, a feast-or-famine scenario. Earon noted the surge of interest and use during the California earthquake several years ago and Operation Desert Storm in 1991.
Beyond the catastrophe model, there are banks in New Jersey that have set up remote cameras in shopping centers to allow borrowers to apply for loans at a distance.
One area of interest for Earon is the federal government, especially the military, which tends to be among the first users of sophisticated applications. Her interest is driven by her work in helping organizations plan for the acquisition of VTC.
In a white paper first composed in 1985 and revised innumerable times over the years, Earon laid out seven important steps to successful videoconferencing. They are needs assessment, system design, system management, internal promotion, user training, usage tracking and system expansion.
Strip off all the niceties about learning the technology, its capabilities, features and pitfalls, and you find a critical need to determine how to bring about change in your own group and get everybody on the bandwagon.
"How is a successful videoconferencing system implemented? Very carefully," Earon said. "Be sure everyone is on the same page to start with. The answer is by concentrating on both the human factors and the hardware. Let the business needs drive the technology, not the reverse. If you fail to do this properly, not only will the cause be lost, you may be lost, too. The rewards for a job well done are well worth the risk."
At this point in the evolution of VTC and the continually changing nature of the Internet, Earon said many organizations would be wise to step back and take a breath. Surprisingly, most of those considering starting or expanding their VTC operations are driven not by economics, such as reducing the costs of meetings or travel, but by competition. They are asking questions such as: Can VTC help us get our product to market faster? Can VTC help us satisfy our customers better?
The Department of Defense takes VTC very seriously. It even has a dedicated Web site that details the its VTC standards (disavtc.spawar.navy.mil/new.html). Those were last updated in October 1998.
Klaus Rittenbach, an electronics engineer in the Defense Information Systems Agency's Joint Information Engineering Organization, at the Center for Information Technology Standards, Fort Monmouth, N.J., said the 1998 version of the VTC profile, which covers international standards that are widely accepted and used by industry, added features such as collaborative computing, additional security options, higher quality video at 112-128 kbps and far-end camera control. It is based primarily on the International Telecommunications Union (ITU) H.320 family and the T.120 family of standards.
"We are currently working on an enhanced version of the VTC Profile that will add VTC for LANs using the ITU H.323 family of standards. In the future, these same standards might be used for VTC over the Internet and the NIPRNET," Rittenbach said. "Right now, we have a draft of the enhanced VTC profile, but it still must go through an extensive government and industry review cycle before it becomes official."
Once approved, it will become an appendix of Federal Telecommunications Recommendation (FTR) 1080B, replacing Appendix A of FTR 1080A.
One reason the profile has been useful for improving VTC interoperability in the Defense Department is that it buys its VTC equipment from many vendors. Interoperability results from using the international standards specified in the VTC profile.
A key concern of the Defense Department is security. The approved version includes security requirements using the KIV-7 and KG-194 encryption devices. (Details can be found in the VTC Profile, which can be downloaded from the Web sites, www.ncs.gov/n6 and disavtc.spawar.navy.mil).
Some vendors are inserting KIV-7 encryption devices into their VTC equipment. It takes up the space of a drive bay in a PC. While the Defense Department standard is the VTC profile and its requirements are mandatory for the agency, those requirements remain optional for other government agencies.
For the future of VTC, Rittenbach sees as the main drivers the rapidly decreasing cost of VTC equipment and the communications pipelines, and the Internet's rapid expansion and evolution.
"The rapidly decreasing cost will make VTC more cost effective and more widely used. Acceptance of new standards like H.323 is important for worldwide interoperability. Also, ease of use is important for widespread acceptance," Rittenbach said. "VTC technology needs to be made transparent to the user so that it is as simple as using a telephone. It is very likely that there will be more embedded devices, especially integrated into personal computers.
"Once the Internet evolves to a point where business-quality VTC is practical over the Internet and the NIPRNET, these networks may become the medium of choice for VTC," he said.
