Short for
Video-on-Demand, an umbrella term for a wide set of technologies and companies whose common goal is to enable individuals to select
videos from a central
server for viewing on a television or computer screen. VoD can be used for entertainment (ordering movies transmitted digitally), education (viewing training videos), and
videoconferencing (enhancing presentations with video clips). Although VoD is being used somewhat in all these areas, it is not yet widely implemented. VoD's biggest obstacle is the lack of a network infrastructure that can handle the large amounts of data required by video.
