Abstract
A smart card digital video recorder system provides a smartcard containing a processor and persistent storage device storing a plurality of digital streams and is inserted into an authorized receiving device or a docking station. The invention allows a receiving device to select a specific digital stream from the persistent storage device which is output to the receiving device and displayed to a user. User control commands are accepted via the receiving device and sent through the smartcard system and allow the user to view and listen to stored digital streams with at least the following functions: variable rate fast forward and rewind, frame step, index, pause, variable rate reverse play, variable rate play, and play. The smartcard receives analog signals and digital video signals from the receiving device and converts them into digital streams which are stored on the persistent storage device. Another embodiment of the invention provides a plurality of input signal tuners on the smartcard that accept analog and digital television broadcast signals which are converted into digital streams and stored on the persistent storage device. An electronic program guide is also stored on the persistent storage device which the smartcard delivers portions of to the receiving device upon request from the receiving device.
