Abstract
There are many regulations related to television and video broadcast signals in various countries around the world, especially the developed countries in technology and communication systems including the United States, Japan and the two together using (NTSC) system . So this system was chosen in research to analyze the space of colors in which to enables us to know the nature of this system and the possibility to convert to other working systems (PAL, SECAM ,...) to ensure the exchange of information and video signals through systems of the global direct broadcasting and the Internet. The research has included analysis of the colors according to an international standard (International Commission on Illumination), which represents the evolution of Maxwell triangle to the process of mixing colors and thus determine the color space for this system for parameters (I,Q,Y) and calculate the values of quantitative color as well as the value of grayscale according to mathematical equations and illustrations of this, After that simulate those results in the image have been selected for the test to be analyzed according to the matlab program as it has proved assess the pattern of color change correct outcomes of the application in the analysis provided and the color that fits the selected image.Keywords : color’s system , Commission International (CIE) , National Television System Committee (NTSC).
