Digital media system with request-based merging of metadata from multiple databases

摘要

A digital media system includes a changer control system that controls an optical disc changer. The changer control system includes a local database of metadata records containing information regarding the optical discs in the optical disc changer. The changer control system is also networked to a digital media server that stores digital media files. The digital media server includes a remote database of metadata records containing information regarding the digital media files. The changer control system provides a user interface that allows a user to access information regarding both the optical discs in the optical disc changer and the digital media files stored in the digital media server. To provide this information, a file system of the changer control system creates a merged set of selected metadata records from the local database and the remote database, in response to a request from the user interface.
