A webcast or web event is a broadcast that is conducted using the Internet rather than a satellite for transmitting to audiences anywhere in the world where access to adequate high-speed Internet is available. Presentations can be filmed live on video camera(s) and broadcast in real time using streaming media technology (video, sound and data) to remote audiences or viewed on-demand by individuals or groups at a later time. Contracting with a trusted and reliable audio visual service provider is highly recommended. Bring them into the planning process early and rely on their recommendations for the equipment and services needed for the best results.
Interactivity between groups at different locations over the Internet is complex, so webcasts are primarily used for one-way transfer of information filmed live of a keynote address, panel of speakers, performance, general session, and so on. Although image quality and reliability are always at risk when broadcasting video over the Internet, webcasting is less costly than transmitting to a private Wide Area Network (WAN) or a satellite. Verification in advance of adequate Internet speed at each connecting site will be vitally important, and a back-up plan must be in place in case there is a disruption or failure of the broadcast.
Registration and access to the webcast will typically be handled by your own resources using your database and registration software or spreadsheets. It is possible for individuals to produce informal webcasts without the assistance of professional tech support, but for most business or high level purposes it is advisable to rely on professionals to produce and troubleshoot your event.
Cost of a webcast or web event is dependent upon the level of technical expertise and equipment required to produce the type of event you desire, plus the meeting or event facilities needed if production is to occur before a live audience for distribution in real time to other groups. Webcasts or web events can also be viewed by an unlimited number of participants from desktop computers or mobile devices once they receive a direct link or access code.
