Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
An apparatus (100) for recording information on a recording medium comprising: a processing unit (2) for receiving recording information to be recorded and processing the recording information to output an recording signal (Sr); a multiplexer (6) for multiplexing reproduction apparatus specifying information (Si) which specifies reproduction apparatuses allowed to reproduce the recording signal with additional information (Sad) corresponding to the recording information and outputting an additional signal (Sadd); and a recording unit (5) for recording the recording signal and the additional signal on said recording medium.
Claim 2
Dependent Claim
23 words
An apparatus according to claim 1, wherein said recording unit records the recording signal and the additional signal separately on said recording medium.
Claim 3
Dependent Claim
23 words
An apparatus according to claim 2, wherein said recording unit records the additional signal on said recording medium at an innermost circumferential area.
Claim 4
Dependent Claim
42 words
An apparatus according to claim 1, wherein said recording medium comprises an optical disc, and said recording unit records the additional signal on said optical disc at an area which is read out by an reproduction apparatus prior to the recording signal.
Claim 5
Dependent Claim
24 words
An apparatus according to claim 1, wherein said multiplexer multiplexes the additional information and the reproduction apparatus specifying information by means of time-division multiplexing.
Claim 6
Independent Claim
125 words
An apparatus (200) for reproducing information from a recording medium (D) comprising: a reading unit (10) for reading a recording information from said recording medium and outputting a read-out signal (Sp) , said recording information including main information and additional information including reproduction apparatus specifying information; a demodulator (12) for demodulating the read-out signal and outputting a demodulated signal (Sq); a detecting unit (19) for detecting the reproduction apparatus specifying information from the demodulated signal; a judging unit (19) for judging whether or not said apparatus is specified by the reproduction apparatus specifying information; and a control unit (19) for prohibiting a reproduction of said recording medium when said judging unit judges that said reproduction apparatus is not specified by the reproduction apparatus specifying information.
Claim 7
Dependent Claim
31 words
An apparatus according to claim 6, further comprising an unit (13) for reproducing the main information, and said control unit prohibiting a reproduction of the main information by said reproducing unit.
Claim 8
Dependent Claim
22 words
An apparatus according to claim 6, wherein said reading unit reads out the reproduction apparatus specifying information prior to the main information.
Claim 9
Dependent Claim
31 words
An apparatus according to claim 6, wherein said recording medium comprises an optical disc, and said reading unit reads out the additional information from an innermost area of said optical disc.
Claim 10
Dependent Claim
47 words
An apparatus according to claim 6, further comprising ejecting unit (20) for ejecting said recording medium, and said control means allows said ejecting unit to eject said recording medium when said judging unit judges that said reproduction apparatus is not specified by the reproduction apparatus specifying information.
