to each of a parallel group of bit streams. The data must be divided into transmission blocks, to which the additional check data is added. The vertical redundancy check term usually applies to a single parity bit per bit stream, calculated

independently of all the other bit streams (BIP-8).[1][2] although it could also be used to refer to a longitudinal redundancy check program in c larger Hamming code.[citation needed] This "extra" LRC word at the end of a block of data is very similar to checksum and CRC. Optimal Rectangular Code[edit] Main article: Optimal longitudinal redundancy check pdf Rectangular Code While simple longitudinal parity can only detect errors, it can be combined with additional error control coding, such as a transverse redundancy check, to correct errors. The transverse redundancy check is stored on a dedicated "parity track". Whenever any single bit error occurs in a transmission block of data, such two dimensional parity checking or "two-coordinate
Longitudinal Redundancy Check Definition
parity checking"[3] enables the receiver to use the TRC to detect which byte the error occurred in, and the LRC to detect exactly which track the error occurred in, to discover exactly which bit is in error, and then correct that bit by flipping it.[4][5][6] Pseudocode[edit] International standard ISO 1155[7] states that a longitudinal redundancy check for a sequence of bytes may be computed in software by the following algorithm: Set LRC = 0 For each byte b in the buffer do Set LRC = (LRC + b) AND 0xFF end do Set LRC = (((LRC XOR 0xFF) + 1) AND 0xFF) which can be expressed as "the 8-bit two's-complement value of the sum of all bytes modulo 28" (x AND 0xFF is equivalent to x MOD 28). Many protocols use an XOR-based longitudinal redundancy check byte, (often called block check character or BCC), including the serial line internet protocol (SLIP),[8] the IEC 62056-21 standard for electrical meter reading, smart cards as defined in ISO/IEC 7816, and the ACCESS.bus protocol. An 8-bit LRC such
Day Degaussing Degaussing is a technique for removing magnetization on a cathode ray tube (CRT) monitor. Televisions and cathode longitudinal redundancy check ppt ray tube monitors are susceptible to buildup of magnetic fields. Degaussing longitudinal parity check helps the CRT monitor to repair and correct any visual distortions displayed, thereby improving the
