FIELD: communication. SUBSTANCE: in agreement with proposed method possible coding standard is prepared, data subject to compression are coded and thus compressed each time when proper standard, one of aggregate of standards, is used and degrees of compression of coded data are compared. Data subject to coding are coded each time when proper standard, one of aggregate of standards, is used. Optimal standard ensuring highest degree of compression of identification information on used standard is determined for each file of data subject to coding when specified coded data having highest compression degree are received. EFFECT: improved functional reliability of system and method. 16 cl, 11 dwg
