Abstract
A method of error correcting pulse code modulated data is provided in which the data words and check words are encoded in an error correcting block. The encoded data words may have one of at least two error conditions associated therewith, and the presence of each type of error condition is detected for each word. A corresponding pointer identifying one of these error conditions is added to the data words. In subsequent processing, the kinds of pointers added are discriminated, and the data words are processed on the basis of the results of this discrimination to correct or compensate for error conditions in the data words.
