ABSTRACT:
A video display control system comprises: a video display having a wide format display ratio; a letterbox detector for sampling video information in pictures represented by input video signals having a letterbox format and generating a control signal for enlarging the pictures for substantially filling the video display means with active video, the letterbox format pictures sometimes having auxiliary information disposed in a border area; and, a circuit for preventing the letterbox detector from sampling the video information in any portion of the border area in which the auxiliary information can be expected to be disposed, when present. In the case of logos, which are generally disposed near or at the right side of the lower border, a horizontal sampling range will exclude the right side of each horizontal line.
