Abstract: A system and method are provided for displaying a video composed of images each comprising a predetermined number M of lines and, a predetermined number N of pixels in each line. Values of a predetermined number P of reference pixels for each line of a current image of the video are stored in memory, where P is less than N. For each line of the current image, the value of a parameter associated with the line is determined, with the parameter corresponding to the number of the reference pixels of the line that are black according to a first predetermined criterion. A first nonblack line and a last nonblack line of the current image are determined to serve as a basis for an automatic reframing of the images of the video before display.
