A Method for Forming a Truncated Positional Code System for Transformed Video Images

Abstract

The article substantiates the requirements for the quality characteristics of video information services. It is shown that it is necessary to improve the quality of video information by the following indicators: time delays for video data delivery in terms of ensuring the required completeness; integrity of video information in accordance with the requirements of the application. The consequence of this fact is an imbalance between meeting the requirements for different groups of quality characteristics of video services. A set of measures is used to reduce the load on information and communication systems. One of the key ones is the use of compression technologies to reduce the bit volume. Therefore, the development of new coding technologies in terms of localising the balance between the level of video data compression and its integrity is an urgent scientific and applied problem. The article describes the main stages of creating a method for determining the informative and positional weight for a coding system in a truncated positional basis. For this purpose, a system of mathematical relations is developed to determine the number of admissible sequences. The scientific novelty is as follows. For the first time, a system of correlations has been created to determine the informative and positional weight of the components of the diagonal sequence of a transformant based on the combinatorial configurations. On the basis of experimental studies, it is shown that the developed method has advantages in terms of ensuring the level of video data integrity under conditions of a given compression rate.
