ABSTRACT:
A method of processing binary data, which is preferably a digital television signal, comprises dividing the data into blocks of ten 8-bit words, deriving an 8-bit parity word each digit of which is a parity digit for the corresponding digits of the ten words, deriving an 8-bit check word by binary summing the ten words and forming the check word as the eight least significant bits of the resulting binary sum, subjecting to further processing, for example by magnetic recording and reproduction, the block of words including the parity word and the check word, and thereafter checking the parity word and the check word to reveal errors occuring in the ten words during the further processing.
