Background. The task of data compression is one of the central problems of modern information technologies. With the increase in image and video quality the problem of its lossless compression has become a topical one. It is necessary to develop an efficient algorithm of lossless video data compression. Most of the existing algorithms are not effective enough. The author suggest a promising approach to lossless video compression – fragmentary video compression method based on the concept of the video stream encoded as a sequence of elements of the pre-formed base of elementary images.
Results. Suggested in this work fragmentary compression method allows to achieve high levels of lossless video data compression . Partition of the source video stream into bit planes allows investigating previously inaccessible window configuration scanning, and prior image transformation to Gray codes leads to a significant decrease either in the size of the database elements, or in its entropy.
Conclusion. The results confirm high efficiency of the suggested fragmentary compression method.
