Abstract
Abstract A method and apparatus that uses offset information stored with respect to selectable keys to identify the selectable keys that are enabled during respective states of a playback operation. Once identified, the enabled selectable keys may be distinguished from non-enabled selectable keys visually, or otherwise. The enabled selectable keys may be identified and/or distinguished in at least three circumstances: (1) when a predetermined portion of a playback operation has been reached, (2) when a user input representing a non-enabled selectable key is received, and (3) when a user input representing an information acquisition key for requesting identification of enabled selectable keys is received.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
61 words
An apparatus for identifying at least one enabled selectable key, comprising: an interface unit to receive user input indicating a selected key; and a control unit to determine if said input corresponds to an enabled selection and visually discriminating said enabled selectable keys from non-enabled selectable keys when said determining step determines said selected key is not an enabled selectable key.
Claim 2
Independent Claim
61 words
An apparatus for identifying at least one enabled selectable key, comprising: an interface unit to receive user input indicating a selected key; and a control unit to determine if said input corresponds to an enabled selection and visually discriminating said enabled selectable keys from non-enabled selectable keys when said determining step determines said selected key is not an enabled selectable key.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 , wherein, in performing said determining, said controller reads an offset information from a disc and identifies said at least one enabled selectable key based on said offset information.
Claim 4
Dependent Claim
14 words
The apparatus of claim 2 , wherein said offset information includes an offset address.
Claim 5
Dependent Claim
14 words
The apparatus of claim 2 , wherein said offset information includes an offset flag.
Claim 6
Independent Claim
100 words
An apparatus for identifying at least one enabled selectable key, comprising: an interface unit to receive an input; a control unit to determine if an input corresponds to a request for identification of said at least one enabled selectable key and to identify said at least one enabled selectable key in response to said request for identification; and a selection display unit to visually discriminate said at least one enabled key from a non-enabled selectable key under control of said control unit, which controls said selection display unit based on said identification and in response to said request for identification.
Claim 7
Independent Claim
100 words
An apparatus for identifying at least one enabled selectable key, comprising: an interface unit to receive an input; a control unit to determine if an input corresponds to a request for identification of said at least one enabled selectable key and to identify said at least one enabled selectable key in response to said request for identification; and a selection display unit to visually discriminate said at least one enabled key from a non-enabled selectable key under control of said control unit, which controls said selection display unit based on said identification and in response to said request for identification.
Claim 8
Dependent Claim
34 words
The apparatus of claim 5 , wherein, in performing said identification, said controller reads an offset information from a disc and identifies said at least one enabled selectable key based on said offset information.
Claim 9
Dependent Claim
14 words
The apparatus of claim 6 , wherein said offset information includes an offset address.
Claim 10
Dependent Claim
14 words
The apparatus of claim 6 , wherein said offset information includes an offset flag.
Claim 11
Independent Claim
78 words
A method to identify at least one enabled selectable key, comprising: determining if an input corresponds to a request for identification of said at least one enabled selectable key; identifying said at least one enabled selectable key in response to said request for identification of said at least one enabled selectable key; and visually discriminating said at least one enabled key from a non-enabled selectable key based on said identification and in response to said request for identification.
Claim 12
Independent Claim
78 words
A method to identify at least one enabled selectable key, comprising: determining if an input corresponds to a request for identification of said at least one enabled selectable key; identifying said at least one enabled selectable key in response to said request for identification of said at least one enabled selectable key; and visually discriminating said at least one enabled key from a non-enabled selectable key based on said identification and in response to said request for identification.
Claim 13
Dependent Claim
32 words
The method of claim 9 , wherein said identifying step comprises: reading an offset information from a disc; and identifying said at least one enabled selectable key based on said offset information.
Claim 14
Dependent Claim
14 words
The method of claim 10 , wherein said offset information includes an offset address.
Claim 15
Dependent Claim
14 words
The method of claim 10 , wherein said offset information includes an offset flag.
Claim 16
Independent Claim
54 words
A method to identify at least one enabled selectable key, comprising: receiving user in put indicating a selected key; determining if said selected key is an enabled selectable key; and visually discriminating said enabled selectable keys from non-enabled selectable keys when said determining step determines said selected key is not an enabled selectable key.
Claim 17
Independent Claim
54 words
A method to identify at least one enabled selectable key, comprising: receiving user in put indicating a selected key; determining if said selected key is an enabled selectable key; and visually discriminating said enabled selectable keys from non-enabled selectable keys when said determining step determines said selected key is not an enabled selectable key.
Claim 18
Dependent Claim
29 words
The method of claim 13 , wherein said determining step comprises: reading an offset information from a disc; and identifying said enabled selectable keys based on said offset information.
Claim 19
Dependent Claim
14 words
The method of claim 14 , wherein said offset information includes an offset address.
Claim 20
Dependent Claim
14 words
The method of claim 14 , wherein said offset information includes an offset flag.
