SYSTEM FOR COMPRESSION OF TWO-DIMENSIONAL INFORMATION ARRAY Russian patent published in 1995 - IPC

FIELD: automation, remote control and computer engineering. SUBSTANCE: device has compressed data generation unit 8, recovery unit 9, shift register 10, correction data generation unit 11. Outputs of redundancy reduction unit 4 are connected to group input of compressed data generation unit 8. Compressed data generation unit, recovery unit and correction data generation unit are introduced to restore integer array on the basis compressed information before sending information. This also provides possibility to compute correcting array of differences between source and recovered array and to transmit not only compressed data array but also correcting array of differences. register having M+1 bits, multiplier and M+1 generators of group of normal system right-hand parts are introduced to compress two-dimensional integer information arrays which represent complex non-monotonous dependencies. This is achieved by implementation of regressive compression model of M-th order (M≥ 2) in redundancy reduction unit. EFFECT: decreased redundancy of transmitted information which represents complex non-monotonous two-dimensional dependencies. 10 cl, 1 tbl, 18 dwg
