Abstract
Video signal processing systems and methods for detecting horizontal synchronization signals within video signals. Digital filtering methods are implemented for processing analog video signals to determine time varying characteristics of video signals to detect the starting and ending positions of horizontal synchronization pulses in a video signal with increased accuracy. In addition, adaptive methods are implemented for dynamically determining various video signal parameters over time, such as blanking level BL, threshold value (slice) level and synchronization level SL using information extracted from digitally filtered video signals.
