Summary: A research object is a methods of transmission of picture and sound signals in systems of digital TV broadcasting. Research was carried out by using of materials, which were written by native and foreign scientists for a few last years. Systematized the impact of individual processes the signal image and sound quality of reproduction in the subscriber terminal. Try playing as a comparative depending on the parameters of image compression applied during the transmission of digital television signals, obtained experimental dependences that establish the link between subjective and objective methods of evaluating image quality of digital television. The results can be used in the educational process of training and retraining in the field of television broadcasting and transmission of digital multimedia content by means of telecommunications networks. Results can also be used during the planning and building and operation of digital television broadcasting networks.
