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.
