Abstract
A method for concurrently displaying an image and a video on a display having memory integrated therein comprises receiving position data defining a position of a top image region, receiving video data from a video source, and passing the video data directly to the display, i.e., without first storing the image within video RAM. In a first mode video data is passed directly to the display only when it corresponds to pixels outside of the top image region. In a second mode, video data is passed directly to the display such that entire successive images are wholly displayed within the top image region. The top image region is smaller than the entire display region.
