A good reference for CRC calculations is the section "Error-Detection Mechanisms (CRCs and Checksums)" in chapter 1 of the following book:

"Data Broadcasting", by R. Chernock, R. Crinon, M. Dolan and J. Mick Jr.,  McGraw Hill Publisher, Video/Audio Professional Series.

Dear Simon,

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.

Regards,

Bernhard

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!!
