In telecommunication, a viewdata is a type of information-retrieval service[?] in which a subscriber can (a) access a remote database via a common carrier channel, (b) request data, and (c) receive requested data on a video display over a separate channel.

Note: The access, request, and reception are usually via common carrier broadcast channels. Contrast with teletext.
