Videoconferencing
data sharing
There are a number of different ways of sharing data and collaborating on applications while taking part in a videoconference. Many of these are proprietary, and often have the drawback that they share the data in-band using valuable bandwidth (and computing resources) that would otherwise be available to the video and audio data.

Windows Messenger As has been mentioned, there are no plans to upgrade Microsoft NetMeeting beyond the current version. In the latest operating system to be released by Microsoft XP the Instant Messenger service 'Windows Messenger' has all the functionality of Windows NetMeeting. As well as audio and video conferencing, it also includes a text chat window, shared whiteboard, file transfer, desktop and application sharing, and has a look and feel similar to that of NetMeeting.

data sharing
Videoconferencing applications are real-time applications that generate large amounts of data which need to be transported across networks very quickly to be of use. Even slight delays in the transmission of data can result in impairments to picture or audio quality. For these reasons it makes sense to give the audio and video a clear path, without the extra data traffic of the T.120 session. The out-of-band method relies on a completely separate call being made for the data sharing element of a conference.

data sharing
This is where a maximum bandwidth has been allocated to a videoconference (by choice, due to network capacity, or the limitations of the equipment) and the addition of data sharing is handled within the same connection and hence the same bandwidth limits. Document Camera The simplest way to share data within a videoconference is to point the camera at a printout. This method probably yields the poorest quality, but has been known to work when all else fails!

The standards that are relevant to contemporary videoconferencing are: H.320 for circuit-based networks, such as ISDN, and H.323 for packet-based networks, such as the Internet. Both of these standards are International Telecommunications Union (ITU) Recommendations (the formal name the ITU uses for its standards). They can be found at: http://www.itu.int/rec/recommendation.asp?type=products&parent=TRECh/

data sharing
Data sharing, data exchange, e-collaboration, remote collaboration there are many terms used to describe the simultaneous sharing of a document or application across a network. This is an area of communication that is full of promise and exciting possibilities. Although interactive collaboration of this kind can be useful on its own, productivity is greatly enhanced if the participants are able to talk to each other, and/or see each other. For this reason this guide considers only data sharing within videoconferencing, i.e.
