Abstract

Настоящее изобретение касается устройства обработки данных и способа обработки данных, которые могут улучшить устойчивость к появлению ошибок в данных. В демультиплексоре 25 заменяют в соответствии с правилом сопоставления битов LDPC-кода и битов символов, которые представляют символы, mb битов из битов кода и используют биты кода после замены как биты b символов. Согласно правилу сопоставления, когда группы, в которые сгруппированы биты кода и биты символа в зависимости от вероятности появления ошибок, используют как группы битов кода и группы битов символа соответственно, определяют комбинацию любой группы битов кода и любой группы битов символа, которой должна быть сопоставлена группа битов кода, и количества битов кода и битов символа.
