Abstract

A DRM disk such as a Blu-ray stores content in a high resolution version for playing by a disk player. The disk also stores the same content in a lower resolution version for playing by a secondary device such as a Playstation Portable (PSP). The disk can be engaged with the disk player and the lower resolution format transferred to the secondary player through a mechanism such as a removable medium (e.g., a Sony Memory Stick®) or a USB connection or other means in accordance with DRM restrictions on the disk.

Claims

1-9. -9. (canceled)

10. A disk bearing digital rights management rules (DRM) and at least one complete audio book in at least first and second formats, wherein

the second format is suitable for playing by a player that is not configured for engaging the disk and that is configured for communicating with a first player which is configured for engaging the disk for receiving the second format therefrom, the first player not being able to play the second format.

11. The disk of claim 10, wherein the disk is a Blu-ray disk.

12. The disk of claim 10, wherein the disk is a HD-DVD.

13. A system, comprising:

at least one disk bearing content in at least first and second versions in at least first and second respective formats;

at least a first player configured to engage the disk and play the first version but not being able to play the second version in the second format;

at least a second player not configured to engage the disk, the second player being configured to play content in the second format; and

at least one transfer mechanism disposed to transfer to the second player the second version from the disk when the disk is engaged with the first player.

14. The system of claim 13, wherein the second player is a PSP.

15. The system of claim 13, wherein the second player is a hard disk drive-based player.

16. The system of claim 13, wherein the second player is a wireless telephone.

17. The system of claim 13, wherein the second player is an audio-only player.

18. The system of claim 13, wherein the transfer mechanism does not require the use of an intervening personal computer to transfer the second version from the disk to the second player.

19. The system of claim 13, wherein the system complies with DRM rules.

20. The system of claim 13, wherein the transfer mechanism is a removable medium insertable into both players.

21. The system of claim 13, wherein the transfer mechanism is a universal serial bus (USB) mechanism connectable to both players.
