Abstract

Apparatus for creating video test patterns for outputting to a video test pattern generator enables individual lines to be built from standard components with appropriate parameters. Completed lines are held in a form which is television standard-independent and can be edited numerically or graphically. A test pattern is built from a set of lines and a part or fully completed pattern can be displayed to an operator in a picture representation which simulates the appearance of the test pattern when displayed on a television receiver.
