Abstract
Systems and methods for encoding and decoding serial bit streams are provided. A parity bit is computed for each nibble, with the parity alternating between odd and even in a regular manner for normal data, and with parity having predetermined different patterns to indicate the start of a packet or the end of a packet. Special code words indicate the idle state and an error state. In some systems an extra vertical parity channel is provided in association with a group of data channels, the vertical parity channel effectively providing a protection channel.
