SIGNAL PROCESSING IN END DEVICES OF TELECOMMUNICATION AND MEDIA PATHS
RÉSUMÉ
In the paper, we carry out the analysis of works on the construction of television and multimedia (T and MM) systems, signal processing, transmission, and reproduction. The classification of color perception models and their possible application in the end devices to improve the quality of the transmitted image is provided. The data are presented that indicate the need to use digital adaptive video signal correction systems. As the source image, the image of the color stripes, their digital signals, which are transmitted through end-to-end (T and MM) devices, were selected. The values of signal levels were obtained which can be used to determine the magnitude of the error classified according to the scale of subjective assessments - "no noticeable distortion", "noticeable, but acceptable distortion", and "unacceptable distortion". We also present a comparison of signal levels that were obtained using earlier color perception models with inaccuracies in the description of the blue and yellow color regions.
