Test signals for assessment image quality in HD and UHD TV video path

Abstract

With the creation and international standardization HDTV and UHDTV systems becomes an actual task of specification test signals to be used in the construction and maintenance video path and equipment of this systems. In this paper suggestions are made on the characteristics and parameters of test signals, that can be referred to basic: universal color bar signal used for evaluating quality of color rendering and transient responses and another parameters and test signal for evaluating spatial two-dimensional frequency modulation transfer function of through light-to-light video path. The proposals can be considered as the initial to new step of progress of metrological provision technical implementation HDTV and UHDTV systems.
