ABSTRACT:
A live video is directed to a display buffer of the device. The device is preferably a set top box and a live video frame stored in the display buffer is preferably displayed by a display device coupled to the set top box. The display device is preferably a television. A capture command preferably signals the set top box to store one or more frames of the currently displayed live video. Upon receiving the capture command, the live video is paused, thereby preventing the display buffer from loading subsequent live video frames. The live video is then re-directed to a capture buffer, the live video is un-paused, and a current live video frame is captured from the capture buffer. The captured frame is then stored using a conventional storage medium. After the frame is captured, the live video is re-directed from the capture buffer to the display buffer to resume display of the live video.
