Abstract
A system and method for eliminating flicker in an interlaced video-display image using an input-video processor, a feature-video processor, a frame buffer, an RGB-output processor, an output-video processor, a control processor, and a synchronized-clock doubler. An input video signal is processed as processed component video information and written to a video memory at a horizontal-scan rate and a vertical-scan rate. Based on the input video signal, a vertical-scan synchronization pulse and a horizontal-scan synchronization pulse are generated and then harmonically doubled. The processed component video information is read from the video memory, responsive to the harmonically doubled synchronization pulses, at a harmonically doubled horizontal-scan rate and a harmonically doubled vertical-scan rate, reading in an interlaced format, with each frame being contiguously read twice in a proper odd-even order as when normally read to generate four fields of video information per frame which may be interlaced. The result is a video display image having improved visual characteristics which is harmonic to any one of NTSC, and SECAM broadcast standards.
