Abstract
An error correcting method for use with a continuous serialized stream of digital information, such as present with digitized stereo audio signals, in which data is formatted in frames containing a preselected number of data words, parity words which in combination with data words of other frames enable correction of data in yet other, spatially remote frames, error check words from which errors in any frame may be detected, and frame sync words, and wherein the parity words are encoded from three orthogonal data sets having in common a single data word so that that word can be reconstructed by operating on any of the three sets, thus enabling correction of that word even if one or two of the three sets also contains an error.
