Abstract
Abstract A controller and media-reader are used to identify various physical or logical characteristics of data stored on a pre-recorded medium. These characteristics may include, e.g., the kind of medium, the kind of data, the way the data is segmented or separated, the size of any data segments, the total amount of data or physical size of the medium carrying the data. A controller then compares the identified set of characteristics to stored sets of characteristics which are associated with respective content-identifiers. A successful comparison yields content-identifiers applicable to the data stored on the pre-recorded medium. These content identifiers may be, e.g., information identifying the titles and length of audio or video programs included on the media. The stored sets of characteristic and content identifiers may be located at a remote site.
