scope:
This document 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basis of the specifications originally included in Annex K of CISPR 20:2002/AMD2:2004, the later edition of which has been replaced by CISPR 35:2016. 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 35 for subjective picture assessment. Objective picture assessment, therefore, constitutes an alternative to the subjective method and offers the advantage of direct correlation to the subjective method.
