A tv capture device is described which is incorporated with a conventional tv set or monitor. The data capture device extracts digital data from a composite video-digital signal and allows one to selectively store, retrieve stored information, and display the information on a tv screen or monitor. The apparatus includes a digital data extractor for extracting the digital data from the composite video signal, a memory unit, a permanent storage unit, and a microprocessor for receiving the extracted digital data. The microprocessor is controlled by a remote control device enabling information to be stored and retrieved from storage for display on a tv screen. A digital-video converter is used to convert the extracted digital data to video signals to simultaneously display the extracted digital data with the currently transmitted program.
