摘要： 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.

摘要： A digital video signal processing apparatus and method for adaptive spatio-temporal Y/C separation in multiple directions. In the digital video signal processing apparatus, an adaptive three-dimensional band pass filter (3D BPF) performs Y/C separation using local comb filtering/1D band pass filtering when the edge direction is fixed vertically/horizontally according to spatio-temporal local characteristics of an image using spatio-temporal filters. When the edge direction is not fixed horizontally/vertically, the 3D BPF performs 2D band pass filtering in all directions. Thus, the 3D BPF continuously carries out comb filtering, 1D band pass filtering and 2D band pass filtering according to the spatio-temporal local characteristics of the image.
