ABSTRACT:
A video error/distortion checker generates a difference signal from an input repetitive digital signal and a reference data signal corresponding to the input repetitive digital signal. The difference signal is compared with maximum and minimum threshold values to generate an error signal when the difference signal exceeds either threshold value. The difference signal also is used to generate a running range value that is compared with a total range value to produce the error signal when during one iteration of the repetitive digital signal the difference signal exceeds a specified range defined by the total range value. The error signal is suitably displayed, either visually or alphanumerically or both, so that an operator may recognize the type, severity and location of errors in the repetitive digital signal.
