The concept of copying a lower-resolution version of a film from a packaged media disc to a portable device is not new--in fact, late last year, Fox and Warner released the first standard definition titles to offer this capability (on Live Free, Die Hard and Harry Potter: The Order of the Phoenix, respectively).

Sony today demonstrated the next level of disc copying. At the company's booth at CES, Sony demonstrated how you could put a Blu-ray Disc movie into a Playstation 3 and copy the film to a Playstation Portable or a Memory Stick. "This way, you can have a portable copy you can take with you," explains David Bishop, president of Sony Pictures Home Entertainment.

"There was always the promise of greater interactivity. You'll see that coming in the new year," Bishop added. In addition to the PSP copying example, Sony also demonstrated how you could download ring tones and new content to a BD Live player, using Men in Black as the example.

BD Live is proving to be a big catchphrase at the show: Panasonic announced its BD Live player yesterday, Fox showcased an early version of its Alien vs. Predator multiplayer game at the Blu-ray Disc Association's booth, and Sony showed its interactive Men in Black trivia game. The game was being played by two people in two locations on a Playstation 3.
