The problems of the management of video information’s exchange are very important in the modern aviation complexes of clutters monitoring. Moreover, problem of forming and compression of video information for its transfer in digital links with limited throughput will also be discussed. The analysis of the information flows created by the onboard optical-electronic systems of aviation monitoring complexes are considered in the article. Requirements for data transmission rate from onboard optical-electronic systems on modern inter-chip digital links are considered. Application of methods of MPEG format’s compression can lead to inadmissible loss of information in onboard systems of optical-electronic monitoring. So using of JPEG compression format for onboard optical-electronic monitoring systems is more preferable. The algorithm of images recovery on the basis of discrete cosine Fourier transform to an image matrix for receiving a new matrix of coefficients (process of a space decorrelation) is considered. Inverse Fourier transformation (process of the return space decorrelation) is applied to recovery of the source image. For implementation of an onboard part of the codec it is preferable to use modern EPLD. For implement a receiving part of the codec it would be possible to use hardware or programmatically depending on a type of collection point for information. The format of compression of JPEG provides video transmission without distortions at compression ratio to 16 times.
