The word datacasting can mean simply the distribution, or streaming,

of digital data. However, it is used more specifically to describe digital

television services beyond traditional broadcasting. Broadcasting

(analogue) is thought of as continuous, with a content of linear

narratives, and distributed from one-to-many. Datacasting (digital)

allows for interactive services (such as access to the Internet), data that

you might request on-demand (such as weather reports or stock

quotes) or pay-per-view subscription to giant audio-visual archives

(e.g. TiVo).
