Web conferencing
Encyclopedia
Web conferencing refers to a service that allows conferencing events to be shared with remote locations. Most vendors also provide either a recorded copy of an event, or a means for a subscriber to record an event. The service allows information to be shared simultaneously, across geographically dispersed locations in nearly real-time. Applications for web conferencing include meeting

. A participant can be either an individual person or a group. System requirements that allow individuals within a group to participate as individuals (e.g. when an audience participant asks a question) depend on the size of the group. Handling such requirements is often the responsibility of the group. In general, system requirements depend on the vendor. The service is made possible by Internet technologies, particularly on IP/TCP connections.

Some solutions require additional software to be installed (usually via download) by the presenter and participants, while others eliminate this step by providing physical hardware. Some vendors provide a complete solution while other vendors enhance existing technologies. Most also provide a means of interfacing with email and calendaring clients in order that customers can plan an event and share information about it, in advance.

Support for planning a shared event is typically integrated with calendar and email applications. The method of controlling access to an event is provided by the vendor. Additional value-added features are included as desired by vendors who provide them. As with any technology, these features are limited only by the imagination.

The term webinar is short for Web-based Seminar, a presentation, lecture, workshop or seminar that is transmitted over the Web, specifically a portmanteau of web & seminar, to describe a specific type of web conference. Some argue that webinars might be one-way, from the speaker to the audience with limited audience interaction, so one-way broadcasts are perhaps more accurately called webcast
Webcast

s. Webinars themselves may be more collaborative and include polling and question & answer sessions to allow full participation between the audience and the presenter. In some cases, the presenter may speak over a standard telephone line, while pointing out information being presented onscreen, and the audience can respond over their own telephones, speaker phones allowing the greatest comfort and convenience. There are web conferencing technologies on the market that have incorporated the use of VoIP (voice over Internet protocol) audio technology, to allow for a completely web-based communication. Depending upon the provider, webinars may provide hidden or anonymous participant functionality, making participants unaware of other participants in the same meeting.

For interactive online workshops web conferences are complemented by electronic meeting system

s (EMS) which provide a range of online facilitation tools such as brainstorming and categorization, a range of voting methods or structured discussions, typically with optional anonymity. Typically, EMS do not provide core web conferencing functionality such as screen sharing or voice conferencing though some EMS can control web conferencing sessions.

Features

Other typical features of a web conference include:
  • Slide show 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 (echo'ed 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.)


Web conferencing is often sold as a service, hosted on a web server

 controlled by the vendor. Offerings vary per vendor but most hosted services provide a cost per user per minute model, a monthly flat fee model and a seat model. Some vendors also provide a server side solution which allows the customer to host their own web conferencing service on their own servers.

Standards

Web conferencing technologies are not standardized, which has been a significant factor in the lack of interoperability, transparency, 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:
  • A basic floor control

  • 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)

Deployment models

Web conferencing is available with three models: hosting service, software and appliance.

An appliance, unlike the online hosted solution, it is offered as hardware. It is also known as "in-house" or "on-premise" web conferencing. It is used to conduct live meetings, remote training, or presentations via the Internet.
