20100332240 | DECENTRALIZED ACCOUNT DIGEST USING SIGNED ELECTRONIC RECEIPTS - Decentralized storage of electronic receipts for sharing transaction histories. Merchants generate and digitally sign the electronic receipts for transactions involving electronic content products. The electronic receipts for a user are stored by the user. The user later presents other entities with the electronic receipt as proof of the transaction. The merchants also maintain “graveyard lists,” or lists of cancelled transactions that are used by other merchants to determine whether a particular transaction is still valid. For example, if the electronic content product associated with the particular transaction has been returned or exchanged, the particular transaction is added to the list of cancelled transactions. | 12-30-2010 |

20080317441 | SYSTEMS AND METHODS FOR RECEIVING, STORING, AND RENDERING DIGITAL VIDEO, MUSIC, AND PICTURES ON A PERSONAL MEDIA PLAYER - A personal media player (PMP) uses a digital media processing system—comprising a video rendering subsystem, a music rendering subsystem, and a picture rendering subsystem—to produce moving-video (video), audio (music), still-graphics (picture), and other output rendered from media files ported to the PMP from another source. The PMP further comprises a user interface system, a display unit system, a power source system, and a data port system utilizing Universal Plug and Play functionality, all of which are coupled directly or indirectly to the digital media processing system. The physical components constituting the aforementioned systems and subsystems are then encased in a portable housing unit suitable for hand-held use and ready portability. | 12-25-2008 |
