This Technical Report describes the algorithms used for objective picture assessment in
immunity tests of analogue and digital TV broadcast receivers and associated equipment.
The algorithms used were developed on the basis of the specifications included in Annex K1
of CISPR 20. The method of objective picture assessment described in that annex employs
the same interference mechanism and is based on the same wanted signal definition as
specified in CISPR 20. Objective picture assessment, therefore, constitutes an alternative to
the subjective method and offers the advantage of direct correlation to the subjective method.
