Blu-ray Disc downgradable for PSP viewing coming later this year

Sony demonstrated at CES 2008 a new feature that would allow a PlayStation 3 to prepare a playable movie for the PSP on Memory Stick Duo using a Blu-ray Disc movie as the source.

"This way, you can have a portable copy you can take with you," said David Bishop, president of Sony Pictures Home Entertainment, adding that this was just one of the new features coming to Blu-ray Disc. "There was always the promise of greater interactivity. You'll see that coming in the new year."

The feature will likely be on a disc-by-disc basis, as rather than having the PlayStation 3 re-encode movies for the PSP’s resolution, a PSP-specific version would be stored on the Blu-ray Disc media. This grants the original movie studios’ professional encoding artists to optimize the video for viewing on a handheld system. This also means, however, that current Blu-ray Disc movies may not be able to make the seamless transition to the PSP.

The ability to downgrade a movie to a portable resolution was first seen on Fox’s Live Free, Die Hard and Warner’s Harry Potter: The Order of the Phoenix on standard-definition DVD.

Should this feature truly become commonplace on Blu-ray Disc and DVD movies, then it makes the UMD movie format a rather hard sell. With new UMD movies priced not much cheaper than Blu-ray Disc and DVD, the added utility of having both a home theater and a portable version at one’s disposal could spell the end of the PSP-specific disc format.

It could be done with hardware signature encoding.

Both the PS3 and the PSP have unique hardware signatures that could be combined to both encrypt and watermark the target file, and render the file unusable on anything but the registered target device(s). The private keys would use a combination of the PS3's and the PSP's MAC addresses as the public key to validate the content.

Viola -- DRM problem solved. Everyone who wants to use this feature can only do so if they have the disc and hardware, playable only on the licensed target hardware.

Seriously, this is not a difficult undertaking. I mean, this is Sony's world and they can do whatever they want to, and there's no law that says the ripped movies have to conform to any standard other than what Sony says.

Put mod chip in a PS3 will pretty much make it a universal ripping device. Just wait till someone crack the encryption and or mode the PSP and DRM no more.

You don't need a mod chip, you can already rip and encode bluray movies in linux on the ps3.
