That will allow at preservation of structural - statistical regularity to provide a necessary level of availability, reliability and confidentiality at video data transmission. Providing the required level of availability involves reducing the video volume by 30% compared to the original volume. In this case, the provision of the required level of reliability is confirmed by estimating the peak signal-to-noise ratio for the authorized user, which is PSNRaBT 20 dB. Ensuring the required level of confidentiality is confirmed by estimating the peak signal-to-noise ratio for unauthorized access, which is PSNRHC 9 dB. The scientific novelty of the obtained results lies in the following: for the first time two methods of video image processing at the quantization stage are proposed. The method of using encryption tables has greater cryptographic stability, and the method of using the key matrix has greater speed. At the same time, the use of arithmetic coding will satisfy the need for availability by reducing the initial volume.
