ABSTRACT:
A method and system for time-shifting video. Specifically, in the method a digital input video signal is received at a processor unit, such as a video processor unit (VPU). A live feed of the digital input video signal is provided as a digital output video signal for display. In parallel, the digital input video signal is stored as video frames. Also, the digital input video signal is recorded for time-shifting. An instruction is received to display a previously seen frame of the digital output video signal. The previously seen frame is repeatedly accessed and provided from that the stored video frames. The previously seen frame that was recorded is accessed when available. Thereafter, the method switches from the previously seen frame stored as video frames to the previously seen frame that was recorded for providing as an output for display.
