2. What is Web Conferencing?
● Web conferencing may be used as an
umbrella term for various types of online
collaborative services including web seminars
("webinars"), webcasts, and peer-level web
meetings.
● In general Web Conferencing refers to
conversing with one or multiple people over
the internet.

3. How “IT” Works
● Web conferencing software is invoked by all
participants in a web meeting. Some
technologies include software and functionality
that differs for presenters and attendees.
Software may run as a web browser
application or stand alone computer
application.

4. Examples

5. Operations
● Depending on the technology being used, participants
may speak and listen to audio over standard
telephone lines or via computer microphones and
speakers. Some products allow for use of a webcam
to display participants, while others may require their
own proprietary encoding or externally-provided
encoding of a video feed (for example, from a
professional video camera connected via an IEEE
1394 interface) that is displayed in the session.

6. Features of Web Conferencing
● Slideshow presentations
● Live or streaming video
● VoIP
● Web tours
● Meeting Recording .
● Whiteboard with annotation (allowing the presenter and/or
attendees to highlight or mark items on the slide presentation. Or,
simply make notes on a blank whiteboard.)
● Text chat
● Polls and surveys
● Screen sharing/desktop sharing/application sharing

7. Standards
● Web conferencing technologies are not standardized, which has reduced
interoperability and transparency and increased platform dependence,
security issues, cost and market segmentation. In 2003, the IETF
established a working group to establish a standard for web conferencing,
called "Centralized Conferencing (xcon)". This include(s)
● A binary floor control protocol. Binary Floor Control Protocol (BFCP)[6]
published as RFC 4582
●
A mechanism for membership and authorization control
●
A mechanism to manipulate and describe media "mixing" or "topology"
for multiple media types (audio, video, text)
● A mechanism for notification of conference related events/changes (for
example a floor change)

8. History
● Real-time text chat facilities such as IRC
appeared in the late 1980s.
● Several point-to-point and private-network
video conferencing products were introduced in
the early 1990s, most notably CU-SeeMe.
● In May 1995, PictureTel announced LiveShare
Plus as a general-use data collaboration
product for Windows-based personal
computers.

9. ● In May 1996, Microsoft announced
NetMeeting as an included component in
Internet Explorer 3.0.
● In 1996, PlaceWare was founded as a spinoff
from Xerox PARC.
● In February 1998, Starlight Networks released
StarLive! (the exclamation point being part of
the product name).
● In June 1998, PlaceWare 2.0 Conference
Center was released, allowing up to 1000 live
attendees in a meeting session

10. ● In April 1999, Vstream introduced the Netcall
product for web conferencing as "a fee-based
Internet software utility that lets you send
business presentations and other graphic
information via e-mail to a Vstream server.
● In December 2003, Citrix Systems acquired
Expertcity, giving it the GoToMyPC and
GoToAssist products.
● In January 2003, Macromedia acquired
Presedia, including the Breeze Presentation
product.
