Digital media player with improved user experience
A digital media player with improved user experience is disclosed. In one embodiment, a digital media player storing a database of metadata associated with digital media content determines whether a removable memory device was connected with the digital media player while the digital media player was powered down. The digital media player refreshes the database only if it is determined that the removable memory device was connected with the digital media player while the digital media player was powered down. In another embodiment, the digital media player determines whether the digital media content stored on the removable memory device changed since the database was last updated. The digital media player refreshes the database if it is determined that the digital media content stored on the removable memory device changed since the database was last updated.
1 . A digital media player comprising:
a memory storing a media transfer protocol database; and
circuitry operative to:
(a) determine that digital media content stored on a removable memory device connected with the digital media player changed since the media transfer protocol database was last updated; and
(b) refresh the media transfer protocol database with metadata associated with the digital media content stored in the removable memory device.
2 . The digital media player of claim 1 , wherein the circuitry is operative to perform (b) by refreshing the media transfer protocol database with metadata associated with media-transfer-protocol-stored digital media content but not with metadata associated with mass-storage-class-stored digital media content.
3 . The digital media player of claim 1 , wherein the circuitry is operative to perform (b) by refreshing the media transfer protocol database both with metadata associated with media-transfer-protocol-stored digital media content and with metadata associated with mass-storage-class-stored digital media content.
4 . The digital media player of claim 1 , wherein the circuitry is further operative to:
refresh a user interface database stored in the digital media player with metadata associated with the digital media content stored in the removable memory device.
5 . The digital media player of claim 1 , wherein the circuitry is operative to perform (a) by generating a check sum value from a file allocation table directory structure of the removable memory device and comparing the check sum value with a previously-generated value from the file allocation table directory structure of the removable memory device.
6 . The digital media player of claim 1 , wherein the circuitry is operative to perform (a) by comparing a value of an FSI_Free_Count field in a file allocation table of the removable memory device with a previously-stored value of the FSI_Free_Count field in the file allocation table of the removable memory device.
7 . The digital media player of claim 1 , wherein the circuitry is operative to perform (a) by comparing a value of an FSI_Nxt_Free field in a file allocation table of the removable memory device with a previously-stored value of the FSI_Nxt_Free field in the file allocation table of the removable memory device.
8 . The digital media player of claim 1 , wherein the circuitry is operative to perform (a) by comparing a list of details of a plurality of digital media files on the removable memory device.
9 . The digital media player of claim 1 , wherein the circuitry is operative to perform (a) and (b) during power-up of the digital media player.
10 . The digital media player of claim 1 , wherein the circuitry is operative to perform (a) and (b) while the digital media player is powered-up.
11 . A digital media player comprising:
a memory; and
circuitry operative to:
(a) store digital media content in a removable memory device in communication with the digital media player;
(b) store album art associated with the digital media content in the memory; and
(c) store the album art in the removable memory device;
wherein the album art is portable with the removable memory device and accessible by a second digital player when the removable memory device is placed in communication with the second digital player.
