FIELD: information technologies.
SUBSTANCE: method includes the following steps: A: to fill data to be decoded in a byte interlacer in columns; B: for data in a byte interlacer check field there is a cyclic shift carried out in columns/lines so that data of each line in the check field are orderly check data corresponding to line data in the information field of the byte interlacer; C: using the line method, RS decoding is carried out, all decoded line data are repeatedly recorded into appropriate lines in the information field of the byte interlacer; D: operative data are subtracted in the specified decoded information data from the information field of the byte interlacer in columns.
EFFECT: achievement of optimal interlacing effect.
