ABSTRACT:
A bright video line select display for a waveform monitor is achieved by storing a selected line from a video frame of a digital video input signal. The stored selected line is iteratively substituted for a plurality of video lines during the vertical interval of the digital video input signal. When line select mode is selected, those video lines during the vertical interval are displayed as a waveform, resulting in a brighter display of the selected video line.
