Abstract
Abstract A determination is made whether recording by a recording apparatus is or is not feasible. This determination is made on the basis of whether or not scrambled reception signals can be descrambled. Recording is discontinued when it is determined that descrambling is not feasible. This prevents wasteful recording. A user can check visually and/or audibly to see whether or not descrambling has been effected. The user is thereby apprised of whether or not recording is carried out.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
74 words
A receiving apparatus comprising: receiving means for receiving scrambled signals; recording apparatus connected thereto; descrambling means connected to said receiving means for descrambling said scrambled signals if possible; decision means responsive to said scrambled signals for deciding whether or not said scrambled signals are susceptible to descrambling; and controlling means responsive to said decision means for controlling a recording operation of said recording apparatus based on the results of decision by said decision means.
Claim 2
Dependent Claim
74 words
A receiving apparatus comprising: receiving means for receiving scrambled signals; recording apparatus connected thereto; descrambling means connected to said receiving means for descrambling said scrambled signals if possible; decision means responsive to said scrambled signals for deciding whether or not said scrambled signals are susceptible to descrambling; and controlling means responsive to said decision means for controlling a recording operation of said recording apparatus based on the results of decision by said decision means.
Claim 3
Dependent Claim
51 words
The receiving apparatus as defined in claim 1 wherein said controlling means is configured to receive a signal indicating the current state of said recording apparatus and to control the operation of said recording apparatus based on said signal indicating the current state and results of decision by said decision means.
Claim 4
Dependent Claim
64 words
The receiving apparatus as defined in claim 1 wherein said controlling means is configured to determine the current operating state of said recording apparatus based on sensed changes in current consumption by said recording apparatus and to control operation of said recording apparatus based on the results of the decision by said decision means and the results of judgement of a current operating state.
Claim 5
Dependent Claim
74 words
A receiving apparatus comprising: receiving means for receiving scrambled signals; recording apparatus connected thereto; descrambling means connected to said receiving means for descrambling said scrambled signals if possible; decision means responsive to said scrambled signals for deciding whether or not said scrambled signals are susceptible to descrambling; and recognition means responsive to said decision means for enabling at least one of visual and audible recognition of the results of decision by said decision means.
Claim 6
Dependent Claim
74 words
A receiving apparatus comprising: receiving means for receiving scrambled signals; recording apparatus connected thereto; descrambling means connected to said receiving means for descrambling said scrambled signals if possible; decision means responsive to said scrambled signals for deciding whether or not said scrambled signals are susceptible to descrambling; and recognition means responsive to said decision means for enabling at least one of visual and audible recognition of the results of decision by said decision means.
Claim 7
Dependent Claim
38 words
The receiving apparatus as defined in claim 4 further comprising: audible alarm means for issuing an alarm sound, said recognition means producing an alarm sound from said audible alarm means to facilitate audible recognition of an alarm condition.
Claim 8
Dependent Claim
35 words
The receiving apparatus as defined in claim 4 further comprising: display means for displaying message information, said recognition means displaying said message information on said display means to facilitate visual recognition of an alarm condition.
Claim 9
Dependent Claim
75 words
A timer recording method for recording of descrambled signals based on a preset timing, comprising the steps of: detecting a timer recording mode; deciding whether or not descrambling has been effected when the timer recording mode is detected; if descrambling has been effected, recording the descrambled signals; and if descrambling has not been effected, carrying out at least one of the steps of issuing an alarm, starting then aborting the recording, and issuing a message.
Claim 10
Dependent Claim
75 words
A timer recording method for recording of descrambled signals based on a preset timing, comprising the steps of: detecting a timer recording mode; deciding whether or not descrambling has been effected when the timer recording mode is detected; if descrambling has been effected, recording the descrambled signals; and if descrambling has not been effected, carrying out at least one of the steps of issuing an alarm, starting then aborting the recording, and issuing a message.
Claim 11
Dependent Claim
40 words
The timer recording method as defined in claim 7 further comprising the steps of: determining again if descrambling has been effected and effecting at least one of (a) terminating the alarm and (b) starting recording when descrambling has been effected.
Claim 12
Dependent Claim
81 words
A recording method for recording signals descrambled from scrambled signals if descrambling is feasible, comprising the steps of: determining whether descrambling is feasible; determining whether the recording process is proceeding; deciding if descrambling has been effected if descrambling is feasible and the recording process is proceeding; and if descrambling is not feasible and the recording process is proceeding, carrying out at least one of the steps of issuing an alarm, discontinuing recording, and issuing a message that descrambling is not feasible.
Claim 13
Dependent Claim
81 words
A recording method for recording signals descrambled from scrambled signals if descrambling is feasible, comprising the steps of: determining whether descrambling is feasible; determining whether the recording process is proceeding; deciding if descrambling has been effected if descrambling is feasible and the recording process is proceeding; and if descrambling is not feasible and the recording process is proceeding, carrying out at least one of the steps of issuing an alarm, discontinuing recording, and issuing a message that descrambling is not feasible.
