a set of explicit formulas for designing TV test signals of primary-color encoder have been derived

which can meet the demands of television test signals with different types and encoding modes. In addition

some typical test signals’examples and the results of experiment are given. With quick development of multimedia audiovisual services

this programmable design technique illustrated in this paperwill be a prefered method used for developing advanced videotest devices in a nearfuture.
