This paper treats of compression of digital video signals and the main aim is to probe the possibility of using several discrete transforms besides well-known discrete cosine transform (DCT). Mathematical description of these transforms is presented in the article. DCT and other orthogonal transforms are described here. Matrix notation of computation of two-dimensional transform is also presented. The comparison of the results obtained by application of the transforms on pictures is introduced.
