    Constructing the Code Description Of the Transformant DCT Taking into Account their Structural Features
    (IEEE, 2020) Barannik, N.; Tverdokhlib, V.; Eliseev, E.; Zakomorna, K.; Vorontsova, N.; Shmakov, V.
    An approach to the construction of a code description of DCT transformants, taking into account the structural features of their binary representation, is presented. It is shown that the proposed model for constructing the code has the ability to reduce the initial number of bits, and also allows you to form a code description of the transformant by a set of independent code blocks. This makes it possible to use this coding method in a video bit rate control system.

    Technology Increasing Capacity Protected Channel Delivery Video Data Telecommunication Systems Critical Infrastructure
    (IEEE, 2021) Tverdokhlib, Vitaliy; Zakomorna, K.; Dvukhglavov, D.; Oleksin, O.; Zhuikov, D.; Kryvonos, V.
    The technology of video stream closure has been developed, which is based on the detection and closure of significant structural units. This technology employs the introduction of the closure marker into the code structure of the video stream for use on unmanned aerial vehicles. This makes it possible to meet departmental requirements for the speed of transmission in conditions of increased frame rates. At the same time, the quality of the updated video data is higher than when using other concealment methods. This is since the encoding process takes into account the processing of the base video frame substantial structural units.
