1. A system of time warping for video viewing in a video receiver having a tuner for selecting a video channel and providing a time linear input video signal and a display device for displaying a video signal comprising:

  • a recirculating dynamic buffer coupled to the tuner for continuously receiving the time linear input video signal provided by the tuner so that a segment of the time linear input video signal having a predetermined duration is temporarily stored in the recirculating dynamic buffer;

    control means responsive to a PAUSE command for marking the segment of the time linear video signal stored in the recirculating dynamic buffer with an access point; and

    means for randomly accessing the segment of the time linear video signal stored in the recirculating dynamic buffer to provide an output video signal for display by the display device so that the segment of the time linear video signal can be accessed for subsequent display from the access point simultaneously with continued buffering of the time linear input video signal.
