FIELD: physics.
SUBSTANCE: invention relates to encoding information. Method of coding with differentiated protection, applied to frame (T), includes stages: decomposition of frame (T) into multiple sub-frames with different priority level, application to each received subframe excluding subframe (ST0) of the lowest priority level, the second algebraic correcting code of the given capacity, which increases with the lowering of the priority level of each subframe when the number of subframes (ST0, ST1) is at least equal to three; application of bit alternation of all subframes so that arrangement in accordance between systematic variable vertices of the first systematic correcting code located in accordance with their degree value, and in accordance with their priority level; encoding using a first systematic corrective code, a frame composed of alternating bits of all logically related sub frames.
EFFECT: technical result of the invention consists in the possibility of providing the correct transmission of information with a sufficient level of reliability corresponding to the priority level.
