Abstract
Abstract An input section inputs a recording signal to be recorded on a recording medium. An identification signal generator generates a predetermined identification signal. A processor is connected to the input section and the identification signal generator, and selectively processes the recording signal and the identification signal. A detector is connected to the input section, the identification signal generator, and the processor, and detects the presence of a recording restriction signal from the recording signal so as to control the processor in accordance with a detection result. A recording section receives an output signal from the processor, and records the signal on the recording medium.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A recording/reproducing system comprising: generating means for generating a specific identification signal particular to the recording/reproducing system; recording means for adding the specific identification signal generated by said generating means to a recording signal and recording the recording signal including the specific identification signal on a recording medium; selection means for selecting, based on a predetermined input signal, whether a selected recording medium includes a selected recording signal having a selected identification signal; detection means for detecting the selected identification signal added to the selected recording signal from a signal read from said selected recording medium if the selection means indicates that the selected recording signal includes a selected identification signal; discrimination means for determining whether the selected identification signal detected by said detection means substantially coincides with the specific identification signal; and disturbing means for disturbing the signal read from said recording medium when said discrimination means determines the selected identification signal does not coincide with the specific identification signal.
Claim 2
Dependent Claim
161 words
A recording/reproducing system comprising: generating means for generating a specific identification signal particular to the recording/reproducing system; recording means for adding the specific identification signal generated by said generating means to a recording signal and recording the recording signal including the specific identification signal on a recording medium; selection means for selecting, based on a predetermined input signal, whether a selected recording medium includes a selected recording signal having a selected identification signal; detection means for detecting the selected identification signal added to the selected recording signal from a signal read from said selected recording medium if the selection means indicates that the selected recording signal includes a selected identification signal; discrimination means for determining whether the selected identification signal detected by said detection means substantially coincides with the specific identification signal; and disturbing means for disturbing the signal read from said recording medium when said discrimination means determines the selected identification signal does not coincide with the specific identification signal.
Claim 3
Dependent Claim
20 words
A system according to claim 1, wherein said selection means performs selection based on information obtained from the recording signal.
Claim 4
Dependent Claim
22 words
A system according to claim 1, wherein said selection means performs selection based on a signal supplied upon a predetermined key operation.
Claim 5
Dependent Claim
19 words
A system according to claim 1, wherein said generating means is detachable with a body of said recording/reproducing system.
Claim 6
Dependent Claim
120 words
A recording/reproducing system comprising: generating means for generating a specific identification signal particular to the recording/reproducing system; recording means for at least partially encoding a recording signal by using the specific identification signal generated by said generating means, and recording an encoded recording signal on a recording medium; selection means for selecting, based on a predetermined input signal, whether an encoding operation by said recording means using the specific identification signal is performed; discrimination means for determining whether a signal read from the recording medium is encoded; and decoding means for decoding the signal read from said recording medium based on the specific identification signal or a signal associated therewith when said discrimination means determines that the signal is encoded.
Claim 7
Dependent Claim
120 words
A recording/reproducing system comprising: generating means for generating a specific identification signal particular to the recording/reproducing system; recording means for at least partially encoding a recording signal by using the specific identification signal generated by said generating means, and recording an encoded recording signal on a recording medium; selection means for selecting, based on a predetermined input signal, whether an encoding operation by said recording means using the specific identification signal is performed; discrimination means for determining whether a signal read from the recording medium is encoded; and decoding means for decoding the signal read from said recording medium based on the specific identification signal or a signal associated therewith when said discrimination means determines that the signal is encoded.
Claim 8
Dependent Claim
20 words
A system according to claim 5, wherein said selection means performs selection based on information obtained from the recording signal.
Claim 9
Dependent Claim
22 words
A system according to claim 5, wherein said selection means performs selection based on a signal supplied upon a predetermined key operation.
Claim 10
Dependent Claim
19 words
A system according to claim 5, wherein said generating means is detachable with a body of said recording/reproducing system.
Claim 11
Independent Claim
125 words
A method of processing a signal comprising the steps of: recording with a recorder, including: inputting a recording signal; generating a recording identification signal particular to the recorder; combining the recording signal and the recording identification signal; and recording the combination; and reproducing with a reproducer, including: selecting a selected recording medium including a selected recording signal; detecting whether the recording medium includes an identification signal; generating a reproducing identification signal particular to the reproducer; decombining the recording signal and the selected identification signal if the detecting step determines the recording medium includes an identification signal; comparing the selected identification signal with the reproducing identification signal; outputting the selected recording signal if the selected identification signal is substantially the same as the selected identification signal.
Claim 12
Independent Claim
125 words
A method of processing a signal comprising the steps of: recording with a recorder, including: inputting a recording signal; generating a recording identification signal particular to the recorder; combining the recording signal and the recording identification signal; and recording the combination; and reproducing with a reproducer, including: selecting a selected recording medium including a selected recording signal; detecting whether the recording medium includes an identification signal; generating a reproducing identification signal particular to the reproducer; decombining the recording signal and the selected identification signal if the detecting step determines the recording medium includes an identification signal; comparing the selected identification signal with the reproducing identification signal; outputting the selected recording signal if the selected identification signal is substantially the same as the selected identification signal.
