the section “Error-Detection Mechanisms (CRCs and Checksums)” in
chapter 1 of the following book:

Subject: AW: How to compute the
checksum and crc-32 for MPE and ULE
probably the easiest way to find out how
to correctly implement ULE, although not yet the final version :-(,
and particularly the CRC32 is looking into the linuxtv.org source code
where we have contributed and what is meanwhile even part of the latest linux
2.6 kernel.

Betreff: How to compute the
checksum and crc-32 for MPE and ULE
Dear all experts,
Currently
I’m studying the encapsulation method on MPE and ULE. But I’m
confusing on how the crc32 and the checksum been calculate. Are they compute
from the datagram section or the hold packet? I hope somebody can help me or
send me some paper or website related with these topics.. Thanks in advance!!
