Abstract
A technique is described that allows a viewer to eliminate a fixed information band portion of a television image (e.g., a scrolling news “crawl” or fixed advertising band) from a television display by “stretching” the main program portion to fill the screen, effectively pushing the undesired crawl or advertising band off of the display. This eliminates a feature of many television broadcasts that many viewers find distracting and/or annoying, and helps to prevent phosphor burn on phosphor-based display screens.
