Checksum
Variant
Checksum algorithm in use for EPD/POD2 and up is CRC-32/MPEG-2
poly : 0x04C11DB7
ref_in : false
ref_out : false
xor_in : 0xFFFFFFFF
xor_out : 0
Ranges
/* POD1 style - checksum: none */
POD1 : offset=sizeof(header)=4+80 count=sizeof(file )-offset
POD6 : offset=sizeof(header) count=sizeof(file )-offset
/* POD1 style - checksum: crc32::mpeg2 */
EPD : offset=sizeof(header) count=sizeof(file )-offset
POD2 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(file )-offset
/* POD3 style - checksum: crc32::mpeg2 */
POD3 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(header)-offset
POD4 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(header)-offset
POD5 : offset=sizeof(ident)+sizeof(checksum) count=sizeof(header)-offset
Compression
