SINOPSIS

Formats of color images transmitted in the digital air terrestrial television broadcast system DVB-T are analyzed. Directions for further improving scientific methods of digital color image processing along the line of their transmission from the source to the receiver so as to ensure a perceptually precise correspondence between image colors reproduced by TV receivers and original image colors are identified. A method of Munsell renotation system extrapolation in the color space CIE Yxy 1931 up to the real color region, which takes into account the effect of the light intensity value on the color space position of constant color hue lines, as well as algorithms for performing operations on mapping the color gamut of the original image as the color gamut of a digital television, using data of a search table generated on the basis of an extrapolated Munsell renotation system, are described.
