Accessing control method for identifying a recording medium in a jukebox
First Claim
1. A method for identifying the information content of a prerecorded medium comprising the steps of:
- determining a characteristic profile of said information content of said prerecorded medium;
accessing a data storage device having a plurality of stored characteristic profiles, each of said stored characteristic profiles being associated with an information content indicia;
searching said plurality of stored characteristic profiles for one of said plurality of stored characteristic profiles having a first parameter substantially matching a second parameter associated with said determined characteristic profile;
adjusting said second parameter associated with said determined characteristic profile for producing a modified parameter in response to the step of searching failing to find said one of said plurality of stored characteristic profiles having said first parameter substantially matching said second parameter;
searching said plurality of stored characteristic profiles for one of said plurality of stored characteristic profiles having said first parameter substantially matching said modified parameter; and
retrieving said information content indicia associated with said one of said plurality of stored characteristic profiles having said first parameter substantially matching said modified parameter.

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.

2. A content information identification method for use in an information processing system, said content information being stored on a pre-recorded medium according to a relatively unique characteristic profile, said characteristic profile comprising at least one of a plurality of physical and logical characteristics of the storage of said content information on said medium, said content identification method comprising the steps of:
-
constructing said characteristic profile of said content information stored on said medium; establishing a first data structure for use by said system which includes a sufficient number of predefined fields to store said physical and logical characteristics of said constructed characteristic profile; accessing a storage medium containing a plurality of data structures, each of said plurality of data structures having a sufficient number of predefined fields to store a predetermined characteristic profile and at least one predefined field for storing content information indicia related to said predetermined characteristic profile; comparing said characteristic profile stored in said first data structure against said predetermined characteristic profiles stored in said plurality of data structures; and selecting content information indicia stored within a one of said plurality of data structures in response to said step of comparing indicating that said predetermined characteristic profile stored in said one of said plurality of data structures substantially matches said characteristic profile stored in said first data structure.

10. A method for identifying the information content of a prerecorded medium comprising the steps of:
-
determining a characteristic profile of said information content of said prerecorded medium; accessing a data storage device having a plurality of stored characteristic profiles, each of said stored characteristic profiles being associated with an information content indicia; searching said plurality of stored characteristic profiles for a one of said plurality of stored characteristic profiles substantially matching said determined characteristic profile; modifying said determined characteristic profile to produce a modified characteristic profile in response to the step of searching failing to find one of said plurality of stored characteristic profiles substantially matching said determined characteristic profile; searching said plurality of stored characteristic profiles for one of said plurality of stored characteristic profiles substantially matching said modified characteristic profile; and retrieving said information content indicia associated with said one of said plurality of stored characteristic profiles substantially matching said modified characteristic profile. - View Dependent Claims (11, 12)
