EFFICIENT CHANGE TRACKING OF TRANSCODED COPIES

摘要

A method for efficient change tracking of transcoded copies may include receiving a selection of one or more media items to synchronize with a mobile electronic device. The selection may include one or more quality preferences for syncing the one or more media items. Sync metadata may be accessed that is associated with media items stored on the mobile electronic device. A set of media items may be generated to copy to the mobile electronic device based on the selection, one or more quality preferences, and sync metadata. Also the set of media items may be copied to the mobile electronic device.
