ABSTRACT:
Error correcting apparatus is provided for correcting plural channels in error in a parallel channel information system. The information is encoded in a cross-channel direction as well as along the channel length. The encoded message after storage or transmission is decoded in the cross-channel direction and error correction provided in the in-channel direction in a given number of indicated channels. Orthogonally symmetrical redundancy enhances error correction while tending to minimize hardware. Plural independent codes interact to correct the plural channels in error. The error correcting capabilities of the codes may be matched, no limitation thereto intended.
