Refer to crc.c for the working C-code. Below, you will find the CRC-8 and CRC-64 lookup-tables. Find the code used to create the tables here: Compile-CRC-8-Lookup-Table.c, and here Compile-CRC-64-Lookup-Table.c. Notice that the CRC-8 lookup-table represents a perfect and complete 1-to-1 function. This will be explored in the next section.

4. This file is part of the libiberty library. Note that the CRC32 checksum is not calculated using the whole MPEG2 TS but rather one section of the payload - this is highlighted in the code (stufftdt function on line beginning *array++ = 0x73;). I have code that can create a CRC32 checksum for a given section of an MPEG2 Transmission Stream packet, and also check the CRC32 checksum of a given Hier der CRC8 und der CRC32 (kompatibel zum Ethernet CRC32) in C. Der CRC8 eignet sich für kurze Datensätze die selten gesendet werden, wie z.B. kurze Fernsteuerkommandos, Fernthermometer oder ähnliches.

The algorithm is consistent with setting of all bits in the initial CRC, along with negation of the bit pattern of the final running CRC. Help, Creates a crc32 checksum.
