METHOD FOR COMPRESSING AND RESTORING MESSAGES Russian patent published in 2005 - IPC

FIELD: communications.

SUBSTANCE: previously, at transmitting and receiving sides random quadratic matrix is identically generated with size m×m elements and two pairs of random key matrices with sizes N×m and m×N elements. From k frames of colored images with sound signal k of matrices of quantized counts of colored moving image are formed with size M×M×k elements and Z-digit sound vector. Received matrices are transformed to digital form on basis of presentation of each of them in form of result of multiplication of three matrices: random rectangular matrix with size N×m elements, random quadratic matrix with size m×m elements and random rectangular matrix with size m×N elements. Into digital communication channel elements of rectangular matrices of size N×m and m×N elements are transferred. Restoration of images is performed in reversed order.

EFFECT: higher speed of data transfer.
