Abstract
A TV data capture device is used with a TV set or monitor to selectively extract, store, retrieve and display on the TV set or monitor extracted digital data. A composite video-digital signal is received from which digital data is removed by a digital data extractor. A memory unit, a permanent storage unit, and a microprocessor are also provided, enabling the user to store and retrieve from storage selected digital data previously extracted from the composite signal. A digital video converter converts extracted digital data to video signals for display of extracted digital data with the currently transmitted video signal.
