Abstract
Abstract An apparatus reproduces items of information which are recorded on a record carrier (22) (e.g. an optical disc) at predetermined locations within a single, continuous time sequence. The apparatus comprises means (14,21,24,26,28) for reading from part of the same record carrier information defining a user's preferred time sequence for the items recorded on that record carrier and means for reproducing the recorded items in accordance with the preferred time sequence. Compatible recording apparatus comprises input means (36) by which a user can define his/her preferred sequence and means (14,18,20,21,24) for writing information defining the preferred sequence onto an appropriate part of the record carrier.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
82 words
An apparatus for reproducing information recorded on a record carrier, the information comprising a plurality of items which are disposed on the record carrier at predetermined locations within a single, continuous time sequence, the apparatus comprising means for reproducing the recorded items in accordance with a user's preferred time sequence, characterised in that the apparatus further comprises means for reading information defining the preferred reproduction time sequence for the items recorded on that record carrier from part of the record carrier itself.
Claim 2
Independent Claim
82 words
An apparatus for reproducing information recorded on a record carrier, the information comprising a plurality of items which are disposed on the record carrier at predetermined locations within a single, continuous time sequence, the apparatus comprising means for reproducing the recorded items in accordance with a user's preferred time sequence, characterised in that the apparatus further comprises means for reading information defining the preferred reproduction time sequence for the items recorded on that record carrier from part of the record carrier itself.
Claim 3
Dependent Claim
50 words
An apparatus as claimed in Claim 1 wherein the reading means are arranged to read the information defining the preferred sequence from a lead-in part of the record carrier corresponding to locations within the said continuous time sequence distinct from the locations at which the items of information are recorded.
Claim 4
Dependent Claim
38 words
An apparatus as claimed in Claim 2 wherein the reading means are arranged to read the information defining the preferred sequence as part of a table of contents identifying and locating the items recorded on the record carrier.
Claim 5
Dependent Claim
49 words
An apparatus as claimed in Claim 2 wherein the reading means are arranged to read the information defining the preferred sequence from locations within the lead-in part of the record carrier distinct from locations containing a table of contents identifying and locating the items recorded on the record carrier.
Claim 6
Dependent Claim
38 words
An apparatus as claimed in Claim 4 wherein the reading means are arranged to read the information defining the preferred sequence from locations defined by a predetermined offset relative to a starting location of the table of contents.
Claim 7
Dependent Claim
41 words
An apparatus as claimed in Claim 5 further comprising means for displaying character information read from locations within the lead-in part of the record carrier defined by a different predetermined offset relative to the starting location of the table of contents.
Claim 8
Independent Claim
62 words
An apparatus as claimed in any of Claims 4 to 6 wherein the information defining the preferred sequence comprises a list of track numbers, the means for reproducing the stored items being arranged to use the list in conjunction with the table of contents in order to determine the locations within the continuous time sequence of the items in the preferred sequence.
Claim 9
Independent Claim
65 words
An apparatus as claimed in any preceding claim wherein the means for reproducing the recorded items comprises means for reading information recorded in a main data channel of an audio and/or video recording on the record carrier, and the means for reading the information defining the preferred sequence comprises means for reading information recorded in a subcode channel recorded in parallel with the data channel.
