Tverdohlib V. A method for increasing the efficiency of infocommunication systems based on video traffic intensity control

The dissertation is devoted to the solution of an urgent scientific and applied problem, which consists in ensuring the quality of video services at the required level by reducing the time of video traffic delivery delays in the system for providing video services using wireless telecommunication networks. The stages of creating a method for controlling the intensity of video frames at the level of encoding frame segments and their structural components are described, the basic features of which are that for each segment a code description is formed in the form of a set of independent code structures. This allows you to control the bit intensity of the video by changing the number of structural components of the code structure of the transformed frame segment. The method allows to reduce the redundancy of the video frame description by taking into account the structural features of the description of transformants at the level of bit representation. The expediency of an approach based on the exclusion of a number of transformants of a video frame segment with subsequent interpolation to construct a method for controlling the intensity of a video stream with a controlled level of quality is substantiated. A method for controlling the bit intensity of video traffic is being developed based on downsampling of frame slices at the transformants level with their subsequent interpolation, while processing the video stream in real time is provided. To implement the method for controlling the bit rate of video traffic based on downsampling of slices, sets of basic transformants and transformants are preliminarily formed in their structure, which can be thinned out at this stage. Within the framework of the control method, the existence of modes of operation is provided, during which the bit intensity is changed in real time and the error level is corrected, which can be introduced in the process of controlling the value of the video bit intensity.
