Nem új hír, de január végétõl a SMEJ (= Sony Music Entertainment Japan) CD-k is másolásvédettek (egen, a Moment is -_- remélem azért vki lerippeli vhogy). Részletezve (idézet
innen):
"[...] The way the Sony protection system differs from current CCCD technology is that it allows for copying a CD to your computer. The CD's are "specially encoded" and to play/RIP them onto a computer, requires downloading a key off the net from Sony's site (so they are assuming everyone has network access). From that point, you can play the music as often as you'd like on your system but cannot make duplicate copies to other systems, CD's which means whatever gets ripped to disc is probably not MP3 and is most likely utilizing the DRM in WMA (see below). The first RIP (or as they call it, downloading) is free but any additional "downloading" of the CD will cost an additional 200 yen per tune.
(....dögöljenekmeg...)
What this "special encoding" is should be interesting since there is only so much that can be done to the disc and its contents yet still have it playable on consumer CD players. Also, since a key is required for playback, it is probably using the data track (like an enhanced CD or mixed mode disc) or the extended pregap area on a hidden track/CD-ROM ready disc. I just hope it doesn't use erroneous TOC's or dual data tracks such that a CD/DVD-ROM drive will get confused as is the case with other protection methods....
There are some caveats in all this. First, the technology is usable only on Windows based systems (Windows 98SE, Windows ME, Windows 2000 ServicePack2, Windows XP Home Edition/ Professional). Which leaves people like me who use Mac's either A) out in the cold or B) meaning it is a software issue tied to a combination of the encoded format and the DRM that is omnipresent in XP and being infiltrated into 2K and older systems via software updates/newer versions of WMP OR (pure conjecture here on my part), could mean that technically if the disc follows one of the standards with or w/o the errors, there might be a way to bypass this on a Mac (i.e. some drives might ignore it like with current protected discs). The Mac OS (either X or previous systems) does not have any DRM built-in with the exception of what is in QT (but developers need to explicitly turn that on in their content and even then, it is not as draconian as the way WM does DRM). Again, the audio needs to exist somewhere on the disc such that a consumer player will just read/play it once it has ignored the data track. Until more technical details come out, cannot tell how it really works.

Another caveat is what Sony is going to do WRT managing payment transactions from those users outside of Japan who really don't mind downloading additional copies onto other systems.
(na IGEN... jellemzõ, külföldiekre nem gondolnak, mennének a fenébe. -_- Végülis õk is csak potenciális vásárlók...) I don't know if SMEJ thought this part out carefully but if it is typical Japanese business with an insular thinking, they might only be addressing the product being sold to the domestic market and not elsewhere.

3rd caveat is that this thing will be defeated relatively quickly
(ÁMEN!! ) as I really have a difficult time seeing it being any stronger than encryption on DVD's which were engineered with that purpose and pretty quickly defeated (even though it does violate the DMCA). All this stuff on CD are just technical workarounds and futilely attempting to retrofit things onto a technology not designed to handle such things. Plus unless the technology is all hardware based, there is nothing they can do to prevent reproduction except to not release the disc.
(kehehehe... ) Also, anything which can playback and one can see/hear is easily reproducible anyway (a simple fact that all this copy protection jazz seem to forget). While it may not be a true digital copy, one digital to analog downconversion (i.e. standard CD player -> composite audio out -> composite audio in on a computer) isn't going to be a showstopper for someone who just wants to be able to listen to their music on their computer or portable player (unless someone is a pure audiophile who can discern such differences) and has no intention of redistributing them... the industry really has people who cannot see the forest for trees...."
