Persistent bundles over a two dimensional compact set Pierre

The C-structurally stable diffeomorphims of a compact manifold are those that satisfy Axiom A and the strong transversality condition (AS). We generalize the concept of AS from diffeomorphisms to invariant compact subsets. Among other properties, we show the structural stability of the AS invariant compact sets K of surface diffeomorphisms f . Moreover if f̂ is the dynamics of a compact manifold...

Digital Watermarking for DVD . . .

O ne of the most quoted applications for digital watermarking is in the context of copy-protection of digital (multi-)media. In its most basic form a watermark is used as a single bit that indicates whether or not content is copyrighted. By the nature of a watermark, this copy-protection bit is (theoretically) strongly tied to the content: it can only be removed when the content suffers serious...

CD/DVD Copy Protection

Pierre Vermersch

It is absurd and without any scientific interest to try to play off DES against EI, as if the question was to know if one method is better than the other in the absolute. All methodological inventions deserve to be tried and tested. But the question is how apposite are they to their object of study. However, Froese and Gould’s article opens a range of issues that are important and interesting. ...

Dvd Sales and Internet Piracy

Movie studios have long believed that home video recording damages the market for movies broadcast on free television. This issue has gained renewed importance with the advent of highdefinition television, causing movie studios to argue that consumer recording of digital video will result in increased piracy and reduced DVD demand. In contrast, we find that the dominant impact of movie broadcas...
