Abstract
Apparatus for use in a television terminal selectively provides a background audio or video signal or both to accompany display of a screen of textual information. The apparatus comprises a tuning circuit for tuning to a predetermined background channel determined by user selection of a particular textual information screen for display. As a result, dinner music may accompany textual informative screens related to the choice of a meal. Alternatively, instructions on how to purchase a movie might be accompanied in the background by the movie. Either the movie picture or the sound or both may accompany the instruction screen.
