SCROLL CONTROLLING APPARATUS AND METHOD FOR WIDE SCREEN TELEVISION

摘要

a synchronization separating unit(10) for separating horizontal and vertical synchronizations from a video signal; a vertical scroll control unit(20) for outputting the imitated vertical synchronization signals during the time to count the value of horizontal synchronization signals up to the vertical scroll control signal starting at the moment of loading a vertical synchronization; and a horizontal scroll control unit(30) for outputting the imitated horizontal synchronization signal during the time to count the value of its own clock signals up to the value of horizontal scroll control signal starting at the moment of loading a horizontal synchronization to achieve the fine scroll control of the wide screen TV.
