The Video Scene Change Detection (SCD) IP provides a video processing block that implements the scene change detection algorithm. The IP core calculates a histogram on a vertically subsampled luma frame for consecutive frames. The histograms of these frames are then compared using the sum of absolute differences (SAD). This IP core is programmable through a comprehensive register interface to control the frame size, video format, and subsampling value.
