Features


Features
  • Slideshow presentations - where images are presented to the audience and markup tools and a remote mouse pointer are used to engage the audience while the presenter discusses slide content.
  • Live or streaming video - where full motion webcam, digital video camera or multi-media files are pushed to the audience.
  • VoIP - Real time audio communication through the computer via use of headphones and speakers.
  • Web tours - where URLs, data from forms, cookies, scripts and session data can be pushed to other participants enabling them to be pushed though web-based logons, clicks, etc. This type of feature works well when demonstrating websites where users themselves can also participate.
  • Meeting Recording - where presentation activity is recorded on the client side or server side for later viewing and/or distribution.
  • 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 - For live question and answer sessions, limited to the people connected to the meeting. Text chat may be public (echoed to all participants) or private (between 2 participants).
  • Polls and surveys (allows the presenter to conduct questions with multiple choice answers directed to the audience)
  • Screen sharing/desktop sharing/application sharing (where participants can view anything the presenter currently has shown on their screen. Some screen sharing applications allow for remote desktop control, allowing participants to manipulate the presenters screen, although this is not widely used.)
  • A binary floor control protocol. Binary Floor Control Protocol (BFCP) 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)
Other typical features of a web conference include:
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)". The planned deliverables of xcon include:
c
Web conferencing is available with three models: hosting service, software and appliance.
An appliance, unlike the online hosted solution, is offered as hardware. It is also known as "in-house" or "on-premises" web conferencing. It is used to conduct live meetings, remote training, or presentations via the Internet.

History of webex

History Real-time text chat facilities such as IRC appeared in the late 1980s. Web-based chat and instant messaging software appeared in the mid-1990s. The PLATO computer learning system allowed students to collaborate on networked computers to accomplish learning tasks as early as the 1960s, but the early networking was not accomplished via the World Wide Web and PLATO's collaborative goals were not consistent with the presenter-audience dynamic typical of web conferencing systems. Several point-to-point and private-network video conferencing products were introduced in the early 1990s, most notably CU-SeeMe, which was used to link selected schools around the United States of America in real-time collaborative communications as part of the Global Schoolhouse project from Global SchoolNet.
