Kharchenko N. The method of controlling the intensity of video traffic on the end nodes of telecommunication system

The object of study - treatment processes to improve the quality of the video information services video stream in telecommunications systems; purpose of research - to develop a method of video bit rate control to improve the quality of video information services using telecommunications systems; research methods - methods of coding theory and digital image processing, methods of the operations research theory, methods of mathematical statistics; results - theoretical work is to further develop methods for matching characteristics of video traffic dynamically changing parameters telecommunications system; practical value: is provided at a predetermined lower intensity average PSNR for 36,36% compared with the MPEG standard is provided at 16,07 PSNR% higher in the MPEG standard for a given intensity level is provided to reduce the time of transmission of video data from the source to the receiver by an average 23,8% technology for Wi-Fi, provides a reduced utilization switching node by an average of 8,3% at maximum intensity video that provides a reduction in the processing time of the video stream on average 4,8%, provide a low probability of packet loss on average 6 times compared to standard MPEG; novelty - improved method of selecting the type of processing unit predicted frames in video encoding technology, improved methods of encoding predicted frames based on pre-transformation, for the first time developed a method of controlling the bit rate of the video stream based on the use of Lagrange relaxation algorithm; implemented - r/w research №276-4, KNURE educational process; scope - telecommunications.
