Abstract
Multiple scaled videos are created using a single video decoder. A plurality of digital video data streams may be displayed in scaled or full-size on a video display. A viewer may select one or more of the scaled videos for display using a remote control. Downsampled frames may be scrolled into view using the remote control. A viewer may select a video to view in real time at full size or in scaled format.
