Abstract
The technology of compression coding of video data for information communication systems of the air segment is being studied. Distinctive features of the developed technology are the following: structural decomposition of the information space by structural feature; the use of a two-hierarchical scheme of statistical coding. A feature of the proposed technology is the use of a statistical approach in the process of forming the informational part of the codegram and the marker (identifier) of the code structure in the original code sequence. This makes it possible to create conditions for localizing the action of errors that occur in the process of video data delivery in the air segment info-communication systems. A model for evaluating the effectiveness of the proposed video data compression coding technology is created. A feature of the created model is the use of both quantitative and qualitative indicators of data distortions of the video information resource under the conditions of errors in the data transmission channels. A comparative analysis of the developed technology with lossless coding methods (Huffman method) and existing compression coding technologies built on the basis of the JPEG platform is carried out. The advantages of the proposed technology are the provision of localization of the action of errors due to the use of additional service information (identifiers) about the code structure, which is formed in the process of statistical coding of the data of the video information resource.
