3. Object of research: The process of reducing the intensity of the video stream and increasing the efficiency of services in telecommunication systems. Aim of research: It is to develop a method of reducing the intensity of the video in the info-communication systems to improve the quality of video service based on the transformation and coding basic frames. Methods of research: Rationale for ways to improve the quality of video information services with use telecommunications systems was based on a systematic approach, which is based on the theoretical apparatus of research of difficult systems. Development of the method of reducing the intensity of the video stream based on its compact representation performed using positions of the theory information and coding. Results of research: when processing the base frame based on the developed method its intensity decreases relative to the case of processing technology standardized average from 15% to 20% depending on the PSNR; achieves a reduction of imbalance between the intensity and speed of the network on average 12%; the number of operations of the created method based on DNPC transforms by technology JPEG1 will be less on average by 10%, relative to technology JPEG2 achieved reduction in the number of standard operations of multiplication a minimum of 53%, and the number of standard operations of addition / subtraction - a minimum 75%; an average number of transactions for processing video based on compression of basic frame by DNPC transformant reduced on average by 45%. Scientific novelty: 1) first developed the method of forming the basis of bases non-uniform-diagonal principle; 2) first developed encoding method transforms in a non-equilibrium diagonally non-uniform positional reference bases; 3) first developed the technology reconstruction of codified; 4) first constructed a generalized direct and reverse technique of code transformations of diagonals; 5) it was further developed a model to assess the informative presentation fragments of images based on the transformation and identify combinatorial redundancy. The results have been implemented during research and development works carried out at state scientific production enterprise "Association Kommunar", scientific and technical specialized engineering bureau "Polysvit". Area of application: telecommunications.
