Hello all, To complete what Votjech wrote, for technical aspects of RS ID there is a paper about RS ID under the "PAPERS" on my Web site (http://f6cte.free.fr/PAPERS.ZIP).
The hashing method introduced by Votjech is really very powerful and i integrated it in the last RS ID sources (in Pascal). 73 Patrick Selon Vojtech <bubn...@seznam.cz>: > > Reed-Solomon identification it is Google-able.
