Webperiod, the video data should be driven low. In the sync generator Verilog module, there is code that ORs the two blanking signals together to make a single active-low “blank_n” signal. This signal is checked within the color generator module to determine whether to drive the color signals low, or to display color data. WebDec 18, 2015 · Before and after these sync pulses, there is a safe margin (called porch) which separate the sync pulses from the image content. During the sync and porch time, the pixel color lines should be driven low (black) to achieve a proper synchronization. Catode ray tubes need these extra times, to bring the catode ray back to the left/top side.
