- step S010 the reservation setting unit 401 of the recording reservation device 40
- the recorder 20 and the network control unit 214 of the recorder 30 are always energized and can receive an instruction sent via the network 10 at any time.
- the network control unit 214 can turn on the power of the recorder and allow the entire recorder to function. Therefore, even if the power of the recorder is apparently turned off, each recorder can perform processing in response to an instruction from the recording reservation device 40 and return a response to the instruction to the recording reservation device 40.
- Such a function using the network control unit 214 is realized, for example, by implementing WOL (Wake On LAN) or a function equivalent thereto.
- the recorder 20 and the recorder 30 transfer the information of the loaded recording medium to the recording reservation device 40.
- the contents of this information are the exchangeable Z non-exchangeable recording medium, the remaining recordable time (or the remaining recordable data amount), the write protect state, and the value of the identifier.
- the timing at which the reservation setting unit 401 instructs to send information about the recording medium is set immediately before the recording reservation time. It is necessary to give a warning to the user and allow time for the user to respond. Also, if the existence of the disc is confirmed long before the scheduled recording time, the disc is locked after the confirmation and the recorder can no longer be used until the lock is released. If the lock is artificially unlocked, the reset may be forgotten and the recording may fail There is also.
- step S020 the reservation setting unit 401 of the recording reservation device 40 receives information on the loaded recording medium from each recorder, and confirms that the optical disk 205a to be recorded exists. Specifically, the reservation setting unit 401 confirms that the optical disk 205a exists by acquiring the identifier “2011”. Further, in the next step 030, the reservation setting unit 401 confirms that the optical disk 205a is stored in the recorder 20.
- step S040 the reservation setting unit 401 confirms that the optical disk 205a is not in a write-protected state, that is, that recording is possible. After confirmation, processing proceeds to step S050.
- step S050 the reservation setting unit 401 confirms that the remaining recordable time of the optical disc 205a is equal to or longer than the broadcast time of the program to be recorded. For example, when the remaining recordable time is given from the recorder 20, the reservation setting unit 401 may compare the time with the broadcast time of the reserved program. When the remaining recordable data amount is given from the recorder 20, the reservation setting unit 401 divides the value of the data amount by the recording bit rate specified at the time of the reservation to record the remaining recordable amount. The time may be calculated and compared with the broadcast time of the reserved program. If the remaining recordable time of the optical disk 205a is longer than the broadcast time of the program to be recorded, the process proceeds to step S060.
- step S060 the reservation setting unit 401 causes the recorder 20 to execute recording.
- step S060 a command to lock the disk is issued to the recorder 20 to prohibit the removal of the disk.
- the reason for locking is to prevent the user from accidentally removing the recording disk immediately before or during scheduled recording.
- the reservation setting unit 401 sends reservation information to the recorder 20.
- the reservation information includes at least the target medium being the optical disk 205a having the identifier “2011”, the recording start time and the recording end time, and the channel information.
- the reservation setting unit 401 instructs the recorder 20 to execute the reservation recording according to the reservation information.
- the recorder 20 performs recording according to the reservation information.
- Step S08 In 0, after the recording is completed, the reservation setting unit 401 instructs the recorder 20 to release the disk lock.
- optical disc 205a is loaded in the recorder 20.
- the reservation setting unit 401 outputs an instruction to the recorder 30, and the other is the same.
- Recording reservation can also be made to the hard disk 205b.
- the reservation setting operation at this time is almost the same as the recording reservation processing for the optical disk 205a.
- disk lock Z unlock is not performed because it is not necessary.
- the designation of the target recording medium may be simply specified as a hard disk without specifying an identifier.
- optical disk 305 having "11" is not loaded in the recorder 20 or the recorder 30 even if it is shifted.
- the description of the same operations as those described above will be omitted.
- the reservation setting unit 401 instructs the recorder 20 and the recorder 30 to send information on the recording medium.
- the recorder 20 and the recorder 30 transfer information on the loaded recording medium to the recording reservation device 40. Since the identifier “3011” does not exist under the above conditions, the reservation setting unit 401 determines that the optical disk 305 does not exist. As a result, the process proceeds to step S110.
- the identifier may not be read due to contamination attached to the optical disk in some cases. Also, when the optical disk is not loaded into the recorder, there is no identifier to be read. In such a case, information indicating non-detection of the identifier or an identifier having a specific value may be sent as information on the recording medium. As a result, the reservation setting unit 401 can determine that the optical disk to be reserved is loaded in the recorder of the transmission source, and that it is !! The reservation setting unit 401 of the recording reservation device 40 receives the information of the recording medium or the information indicating the non-detection of the identifier from each recorder and stores it in the medium storage unit 403.

This is the subject of the reservation This is because a certain optical disk 305 is also stored in a misaligned recorder, which is an error state.
- step S120 the reservation setting unit 401 searches for another recording medium to save the program to be reserved.
- the reservation setting unit 401 refers to the information on the recording medium of each recorder stored in the medium storage unit 403.
- the reservation setting unit 401 preferentially searches for an irreplaceable recording medium (also referred to as a fixed recording medium) as a target for evacuation recording.
- the reason for giving priority to the fixed recording medium is that if evacuation recording is performed on a removable optical disk, that optical disk will be taken out by another user, making it difficult for the user who set the reservation to watch the program. It is.
- a hard disk which is an example of a non-replaceable recording medium
- the reservation setting unit 401 selects the hard disk 205b of the recorder 20 as a target of the evacuation recording.
- scramble that can be canceled only by the user who made the recording can be applied to the recorded program.
- Such scrambling is canceled by, for example, inputting a password which is set by the user in advance.
- reservation setting section 401 checks whether or not recording is possible in recorder 20 to be subjected to evacuation recording. For example, the reservation setting unit 401 inquires of the recorder 20 about the remaining time that can be recorded on the hard disk 205b and the recording time of the program reserved for recording, and obtains information on each time. Then, when the recording time of the program to be saved and the total time of the recording time are shorter than the remaining time, it is determined that recording is possible. Alternatively, it may be determined that recording is possible when the remaining time that can be recorded on the hard disk 205b is longer than the recording time of the program for which evacuation recording is to be performed.
- steps S120 and S130 are described as separate processing blocks, they may be integrated.
- the medium storage unit 403 of the recording reservation device 40 Time information may be acquired in advance, and when preferentially searching for a non-replaceable recording medium, the recording medium on which the evacuation recording is performed may be determined in consideration of the information.
