Published from December, commercial Blu-ray discs have to support the so-called "managed copy", ie the possibility of legal copies (make at least one) of the disc for personal use to be able to (eg the contents of the purchased Blu-ray Disc for a portable player like an iPod or convert easily create a backup). Take advantage of this right (enshrined in the U.S. as in Germany) is due to the AACS copy protection is not possible through legal means, so far can only be by illegal means the Blu-ray circumvent copy protection. "Managed Copy" but that must also be supported by the disc as used by the Blu-ray player should just be made this possible: the player takes on the internet contact with an authentication server that makes it right, it is confirmed but also a legal DRM-protected copy (either exactly or less to produce scaled). The right holder may also require the copy for a fee. Unfortunately, this possibility is still only theoretical: so far no player supports "managed copy" and there is no need for the authentication server - until March 2010 there should be some. Although not even a player has been announced that will support Managed Copy, "are the first products likely (PC Blu-ray player) next year expected by the new feature can also make use of. For all Blu-ray Disc owners in any case it would be a welcome opportunity to finally watch the movie I purchased through other media on other devices. An opinion poll of RealNetworks (even just because of its RealDVD copying software in court, so of course not exactly an impartial source ..) that are at least 90% of users want to be such an option. Interestingly then, of course, whether the studios will demand a price that is perceived by users as "fair" and not limit the copy option too draconian.
