Abstract
A system is provided by which a single active video signal, along with a plurality of audio and data streams can be made to represent a number of different screens of information at a cable TV set. The system uses essentially only the bandwidth of a single video channel to provide a viewer with a plurality of screens, one or more of which include the same active video picture, simultaneously with other screens which display only audio and text/graphics. This multiple-screen capability is provided by a mapping function which creates an effective plurality of channels that are dynamically and seamlessly switched.
