In the prior art, data is encoded in two 16-bit code words each containing eight bits of data and eight bits of redundancy. The properties of the code are such that if there were nine bits of data and eight bits of redundancy (an additional data bit), the redundant code would be capable of correcting any single or double error in the 17 bits. The 17th bit is not now part of the 16 bits encoded. The code structure is repeated twice together to form 32 bits, 16 bits of data in two bytes, each byte encoded with an additional byte of redundancy to form a half-rate code.
