Abstract
Abstract If only any one of a pair of an SS anti-duplication control signal S 5 and copy guard signal S 6 generated correlatively each other added on the video signal played back from the disk is detected, or if the specific anti-duplication control signal is not detected, the video signal recorded in the disk is judged to be an illegally duplicated video signal, and the output control signal generation section controls the output control section so as not to output the playback video signal S 4.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
89 words
An apparatus for controlling a recording of an information signal on a recording medium comprising: first detecting means for detecting a first copy control signal related to said information signal; second detecting means for detecting a second copy control signal related to said information signal; and control means for inhibiting said recording of said information signal on said recording medium when at least one of said first and second copy control signals is detected and when at least one of said detected copy control signals indicates a copy inhibit.
Claim 2
Independent Claim
89 words
An apparatus for controlling a recording of an information signal on a recording medium comprising: first detecting means for detecting a first copy control signal related to said information signal; second detecting means for detecting a second copy control signal related to said information signal; and control means for inhibiting said recording of said information signal on said recording medium when at least one of said first and second copy control signals is detected and when at least one of said detected copy control signals indicates a copy inhibit.
Claim 3
Dependent Claim
31 words
The apparatus according to claim 1 , wherein when only one of said first and second copy control signals is detected said control means inhibits said recording of said information signal.
Claim 4
Dependent Claim
30 words
The apparatus according to claim 1 , wherein when neither of said first and second copy control signals is detected said control means permits said recording of said information signal.
Claim 5
Dependent Claim
56 words
The apparatus according to claim 1 , wherein when both of said first and second copy control signals are detected said control means records the copy control signal having a stricter duplication information, and when only one of said first and second copy control signals is detected said control means records said detected copy control signal.
Claim 6
Independent Claim
81 words
A method for controlling a recording of an information signal on a recording medium comprising the steps of: detecting a first copy control signal related to said information signal; detecting a second copy control signal related to said information signal; and inhibiting said recording of said information signal on said recording medium when at least one of said first and second copy control signals is detected and when at least one of said detected copy control signals indicates a copy inhibit.
Claim 7
Independent Claim
81 words
A method for controlling a recording of an information signal on a recording medium comprising the steps of: detecting a first copy control signal related to said information signal; detecting a second copy control signal related to said information signal; and inhibiting said recording of said information signal on said recording medium when at least one of said first and second copy control signals is detected and when at least one of said detected copy control signals indicates a copy inhibit.
Claim 8
Dependent Claim
29 words
The method according to claim 5 , wherein when only one of said first and second copy control signals is detected said recording of said information signal is inhibited.
Claim 9
Dependent Claim
28 words
The method according to claim 5 , wherein when neither of said first and second copy control signals is detected said recording of said information signal is permitted.
Claim 10
Dependent Claim
52 words
The method according to claim 5 , wherein when both of said first and second copy control signals are detected the copy control signal having a stricter duplication information is recorded, and when only one of said first and second copy control signals is detected the detected copy control signal is recorded.
