FIELD: electrical communications; data processing including reduction of data redundancy. ^ SUBSTANCE: proposed process includes similar way of generation of random quadrature matrix measuring m x m items and k random key matrices measuring N x m and m x N items on sending and receiving ends. Then k matrices of quantum readings of motionless gray-level video picture measuring M x M items are formed from k motionless gray-level video pictures which are then converted into product of three following matrices: random rectangular matrix measuring N x m items, random square matrix measuring m x m items, and random rectangular matrix measuring m x N items; in the process items of rectangular matrix measuring N x m items are transferred to communication channel. On receiving end k matrices of recovered quantum readings of motionless gray-level video pictures measuring M x M items are formed around random matrix measuring N x m items received from communication channel, as well as around random quadrature matrix measuring m x m items, and random rectangular matrix measuring m x N items, and motionless gray-level video pictures are produced from mentioned k matrices of recovered quantum readings. ^ EFFECT: enhanced data transfer speed at desired quality of recovered messages. ^ 4 cl, 24 dwg |
