Abstract
A video storage arrangement produces a continuous video signal representing a test pattern. One luminance frame store is provided and two chrominance frame stores. A selection can be made between NTSC, and SECAM modes. Switches are provided for selecting between chrominance frame stores and between inverting and non-inverting mode. Depending upon the selected broadcast standard, these switches are driven from field and line clock signals to generate the required output field sequence in YC or composite form.
