Constraction Test Materials for Assesment Broadcasting Video Path

The analysis of metrological agents for the estimation of the quality of telecommunication path treatments is carried out. The analysis of subjective and objective estimation methods is presented. The justification for choosing an objective method of measuring is presented. A list of existing goals and objectives, which face the current progress of the implementation of promising systems for broadcasting and improvement of existing ones are reported. The latter include the absence of normative documents and recommendations for optical specimens for testing tables, etc. Research related to the choice of optical samples from existing sets of colors from a number of international documents and recommendations are presented. Deficiency of these sets is substantiated, as some of the colors necessary for evaluation of telecommunication paths cannot be provided with no color of sets. Provides recommendations and refinements about which colors from existing sets should be used and what constraints exist when used and how to solve. It is shown, that saturated colors of green and red colors are not provided with spectral from the existing sets, therefore, it is proposed to expand the traditional understanding of metrological means by using atlases of colors. Satin colors in contrast to existing ones have a number of advantages and can be used for evaluation in advanced conditions, rather than in the studio that is rigidly defined by the regulations. It is noted that for different brightness values there are a different number of testing points. The number of testing points directly depends on the evaluation criteria and is driven by several possible sets of colors for evaluation. Recommendations for other evaluation conditions are provided. Satin colors are used to construct testing tables.
