This paper treats of compression of digital video signals and the mainaim is to probe the possibility of using several discrete transformsbesides well-known discrete cosine transform (DCT). Mathematicaldescription of these transforms is presented in the article. DCT andother orthogonal transforms are described here. Matrix notation ofcomputation of two-dimensional transform is also presented. Thecomparison of the results obtained by application of the transforms onpictures is introduced.
