Description

  The present invention relates to a recording device, a recording agent system, and a recording reservation information management server that allow other recording devices to perform recording processing based on the recording reservation information when the recording reservation information reserved for recording by the own recording device cannot be executed.

  In recent years, many products around us are driven by electricity supplied from power plants. When there is a risk that the power demand for this power plant will be tight for some reason, a planned power outage may be performed in a time zone predetermined for each region. Since no power is supplied during a power failure, it is not possible to use an electrical product that does not have an internal power source such as a battery. Therefore, when a power failure occurs, for example, it becomes impossible to perform program recording by a recorder.

  In this regard, a technique is known in which a recording agent is performed by another device capable of recording. For example, there is a technique in which a server records program data broadcast from a broadcasting station in response to a recording request from a user and distributes the recorded program data to a terminal in response to a viewing request from the user. It is known (see, for example, Patent Document 1).

  The identification ID is composed of identification information and a management ID of recording reservation information registered in the recording reservation information management table 23. In the identification information, “S” indicating that it is recording reservation information requested for substitution, “R” indicating that it is recording reservation information for substitution recording, or recording reservation information that is recording reservation information of the own apparatus and substitution recording is performed. There is “W” indicating information. For example, “R-001” indicates that the recorder 5 performs the recording reservation for the recording reservation information of the management ID “001” in the recording reservation information management table 23. “S-003” indicates that the recorder 5 has requested recording for the recording reservation information of the management ID “003” in the recording reservation information management table 23. “W-004” indicates that the recording reservation information that the recorder 5 records for itself and the recording reservation information that substitutes for recording (management ID “004” in the recording reservation information management table 23) overlap. No recording ID is added to recording reservation information for recording only for itself, that is, recording reservation information of the own device that is not registered in the recording reservation information management table 23.

The recording reservation execution date and time is the date and time when the recorder 5 accepts the recording reservation.
The network name is the name of the network on which the program reserved for recording is broadcast.
The CH name, program name, recording start date / time, and recording end date / time are information related to the program reserved for recording, and correspond to the CH name, program name, broadcast start date / time, and broadcast end date / time, respectively.
The recording option information is recording setting information related to recording image quality, recording sound quality, and the like at the time of recording.

  Returning to FIG. 1, the power failure time storage unit 54 of the recorder 5 stores the postal code of the location of the recorder 5 and the power failure time information that is the time when the recorder 5 is turned off due to a planned power failure or the like. Yes. With reference to FIG. 5, a state where the postal code and the power failure time information are set in the power failure time storage unit 54 will be described.

  First, as shown in FIG. 5A, the recording processing unit 52 displays a postal code input screen for inputting the postal code of the location of the recorder 5 on a display unit (not shown) in accordance with a user's remote control operation or the like. Let This display unit may be provided in the recorder 5 or may be provided in a television connected to the recorder 5. The recording processing unit 52 acquires the zip code input by the user via the zip code input screen and stores it in the power failure time storage unit 54. If a zip code has already been set in the initial setting of the recorder 5, the zip code may be stored in the power failure time storage unit 54.

  Next, the recording processing unit 52 accesses the power failure information management server 1 via the Internet 4 and refers to the power failure information management table 13 to acquire a power failure group and a power failure date and time corresponding to the zip code. The recording processing unit 52 stores the acquired power failure group and the power failure date and time of the power failure group in the power failure time storage unit 54 in association with the zip code, and completes the setting of the power failure information (FIG. 5B). Note that the recording processing unit 52 may cause the user to input a power outage group and acquire the power outage time corresponding to the input power outage group from the power outage information management table 13 via the Internet 4. The recording processing unit 52 may notify whether or not the recording time zone of the recording reservation information registered in the recording reservation table 53 overlaps with the power failure time stored in the power failure time storage unit 54 in accordance with a user operation. .

  When the registered content of the power failure information management table 13 is updated, such as a change in power failure group or power failure time, the power failure information management server 1 notifies each recorder 5 that the power failure information has been changed. When the recording processing unit 52 obtains notification that the power outage information has been changed, as shown in FIG. 5C, the recording processing unit 52 notifies the user that the power outage group has been changed and resets the power outage group to the user. You may be encouraged.

  In addition, the recording processing unit 52 has a substitute recording menu regarding substitute recording. FIG. 6 is an example of a substitute recording menu. The menu items of the substitute recording menu include “sending recording reservation information to server”, “recording option non-matching permission setting”, and “recording reservation information search on server”.

  “Sending recording reservation information to the server” overlaps the power failure time stored in the power failure time storage unit 54 with the recording time zone (from the recording start date and time to the recording end date and time) of the recording reservation information registered in the recording reservation table 53. In this case, it is a setting as to whether or not to transmit the recording reservation information to the recording reservation information management server 2. When “send” is set, the manufacturer name and model number of the recorder 5 and a recording option mismatch allowable setting value described later are included in the recording reservation information overlapping with the power failure time and transmitted to the recording reservation information management server 2. Are registered in the recording reservation information management table 23. When set to “Do not send”, the recorded program that overlaps the power failure time is not recorded.

  “Recording option non-matching permissible setting” is a setting for whether or not to record with the substitute reservation machine even if the recording option information does not match the recording option information of the own device when the recording reservation is made. The “recording option non-matching allowable setting” can be set only when “send recording reservation information to server” is set to “transmit”. When “allow” is set, recording may be performed according to the recording option of the substitute reservation machine, and recording may not be performed according to the recording option when the recording reservation is made. However, if the setting is “permitted”, the proxy requesting machine and the proxy reservation machine do not have to have the same model number, and it becomes easy to find the proxy reservation machine. If “not allowed” is set, substitute recording by the substitute reservation machine is not performed if the recording cannot be performed according to the recording option when the recording reservation is made.

  “Search for recording reservation information on server” is a setting for whether or not to search for recording reservation information registered in the recording reservation information management table 23 of the recording reservation information management server 2 as a substitute reservation machine. When “search” is set, the recorder 5 searches the recording reservation information management table 23 for the recording reservation information that can be substitute-recorded for the other recorder 5, and performs substitute recording. When “not search” is set, the video recorder 5 does not search the video recording reservation information management table 23 for video recording reservation information that can be video-recorded on behalf of the other video recorder 5, and performs the proxy for the other video recorder 5. Do not record.

  Specifically, with reference to FIG. 7 and FIG. 8, the processing flow of the recording agent system X will be described. It is assumed that the recorder 5 cannot make a recording reservation beyond the recording capability of its own device. For example, it is assumed that the recorder 5 cannot make a recording reservation exceeding the recording capacity of the own device, or can make a reservation for recording a plurality of programs simultaneously exceeding the number of tuners that the own device can use for the recording process. . In the following processing, a case will be described as an example where the proxy reservation machine has a sufficient recording capacity for proxy recording and one tuner. Further, it is assumed that a postal code, a power outage group corresponding to the postal code, and a power outage time are set in advance in the proxy requesting machine and the proxy reservation machine.

  First, in step S11 of FIG. 7, the recording processing unit 52 of the proxy requesting machine periodically determines whether the recording time overlaps with the power failure time stored in the power failure time storage unit 54 for the recording reservation information registered in the recording reservation table 53.

  On the other hand, in the case of Yes in step S12, in step S13, the recording processing unit 52 of the proxy requesting machine determines whether the recording reservation information is transmitted in the preset recording proxy menu, that is, “recording reservation to the server”. It is determined whether “information transmission” is set to “transmit”. In the case of No in step S13, the recording processing unit 52 of the proxy request machine returns the process to step S11.

  On the other hand, in the case of Yes in step S13, in step S14, the recording processing unit 52 of the proxy requesting machine includes the recording reservation information including the manufacturer name and model number and the recording option non-matching allowable setting value in the recording reservation information overlapping with the power failure time. It transmits to the management server 2. In step S15, the recording reservation information management server 2 allocates and registers a management ID to the recording reservation information in the recording reservation information management table 23. In step S <b> 16, the recording processing unit 52 of the substitution requesting machine receives the management ID of the transmitted recording reservation information from the recording reservation information management server 2. In step S17, the recording processing unit 52 of the recording agent registers the identification ID obtained by combining the identification information “S” indicating that the recording request has been made with the management ID in the recording reservation table 53 in association with the recording reservation information. . In step S18, the recording processing unit 52 of the recording agent sets the recording state of the recording information management table 23 of this recording reservation information to “searching for substitute reservation device”.

  On the other hand, in FIG. 8, in the substitute reservation machine, in step S <b> 19, the recording processing unit 52 determines whether or not the recording reservation information search on the server is OK, that is, “recording reservation information search on server” is “ It is determined whether it is set to “Search”. In the case of No in step S19, the recording processing unit 52 returns the process to step S19.

  In the case of Yes in step S19, in step S20, the recording processing unit 52 of the proxy reservation machine periodically searches for recording reservation information in the recording reservation information management table 23 of the recording reservation information management server 2 (step S20 in FIG. 7). See also). In step S21, the recording processing unit 52 of the proxy reservation machine acquires recording reservation information from the recording reservation information management server 2 (see also step S21 in FIG. 7). In step S22, the recording processing unit 52 of the substitute reservation machine determines whether there is recording reservation information whose recording state is “searching for substitute reservation machine” for the recording reservation information acquired from the recording reservation information management server 2. In the case of No in step S22, the recording processing unit 52 returns the process to step S19.

  On the other hand, if Yes in step S22, in step S23, the recording processing unit 52 of the proxy reservation device determines whether the recording start date / time has not reached the current date / time, that is, whether the recording start date / time is later than the current date / time. . In the case of No in step S23, in step S24, the recording processing unit 52 of the proxy reservation machine sets the recording state of the recording reservation information in the recording reservation information management table 23 to “recording failure” (step S24 in FIG. 7). In step S25, the process returns to step S19.

  On the other hand, in the case of Yes in step S23, in step S26, the recording processing unit 52 of the substitute reservation machine stores the recording time zone (from the recording start date and time to the recording end date and time) of the recording reservation information in the power failure time storage unit 54. Determine if it overlaps with the power outage time. If Yes in step S26, the recording processing unit 52 of the proxy reservation machine returns the process to step S19.

  On the other hand, in the case of No in step S26, in step S27, the recording processing unit 52 of the proxy reservation machine records the recording reservation information of the recording requesting machine in the CH of the program information such as EPG (electronic program guide) possessed by itself. Determine if there is CH. In the case of No in step S27, the recording processing unit 52 of the proxy reservation machine records the recorded program because the recorded program is not broadcast at the location of the own device or does not support the recordable network of the own device. It is determined that substitution is impossible, and the process returns to step S19.

  On the other hand, in the case of Yes in step S27, in step S28, the recording processing unit 52 of the proxy reservation machine determines whether the own apparatus is the same manufacturer and the same model number as the proxy requesting machine. In the case of No in step S28, the proxy reservation machine has a manufacturer / model number different from that of the proxy request machine, and therefore may not support the recording option of the proxy request machine. Therefore, in the case of No in step S28, in step S29, the recording processing unit 52 of the proxy reservation machine determines whether the recording option mismatch setting of the recording reservation information of the proxy requesting machine is allowable. In the case of No in step S29, the recording processing unit 52 of the proxy reservation machine returns the process to step S19. On the other hand, in the case of Yes in step S29, in step S30, the recording processing unit 52 of the substitute reservation machine records the recording request machine to record with the recording option of the own apparatus similar to the recording option of the recording reservation information of the substitute request machine. The reservation information is registered in the recording reservation table 53 of the own apparatus to make a recording reservation, and the process proceeds to step S33.

  On the other hand, in the case of Yes in step S28, in step S31, the recording processing unit 52 of the substitute reservation machine reserves the reserved recording reservation information that overlaps the recording time zone of the recording reservation information of the substitute request machine in the recording reservation table 53 of the own apparatus.

  On the other hand, in FIG. 7, in the proxy requesting machine, in step S40, the recording processing unit 52 associates an identification ID with identification information “S” indicating that a recording request has been made in the recording reservation table 53 of the own apparatus. With respect to the recorded recording reservation information, the recording state of the recording reservation information management table 23 is periodically searched using the management ID as a key. In step S41, the recording processing unit 52 of the proxy requesting machine acquires the recording state of the recording reservation information of the own apparatus from the recording information management server 2.

  In step S42, the recording processing unit 52 of the substitution requesting machine determines whether or not the recording state of the recording reservation information for which the recording request has been made has been decided as the substitution booking machine. In the case of No in step S42, the recording processing unit 52 of the proxy request machine returns the process to step S40. On the other hand, if Yes in step S42, the recording processing unit 52 of the proxy requesting machine notifies the user that the recording reservation has been completed in step S43. In step S39, the recording processing unit 52 of the proxy reservation machine may also set the recording state as to whether or not the recording reservation is performed according to the recording option of the proxy requesting machine. In this case, in step S43, when the proxy requesting machine notifies the user that the recording reservation is completed, it can also notify whether or not the recording reservation is completed according to the recording option.

  Thereafter, in the substitute reservation machine, in step S44 of FIG. 8, the recording processing unit 52 executes recording at the recording time according to the recording reservation information in the recording reservation table 53 of the own apparatus. In step S45, when the recording processing unit 52 of the proxy reservation machine finishes executing the recording of the identification ID with “R” or “W” indicating that it is a proxy request in the recording reservation table 53 of the own device, The recording state of the recording reservation information management table 23 corresponding to the management ID is set to “recording complete” (see also step S45 in FIG. 7). Then, in step S46, the recording processing unit 52 of the proxy reservation machine uploads the proxy recording data to the recording data storage server 3 in association with the management ID (see also step S46 in FIG. 7). In response to this, in step S47 of FIG. 7, the recording data storage server 3 associates the recording data uploaded from the substitute reservation machine with the management ID and stores them in the substitute recording data storage unit 33. When the recording processing unit 52 of the proxy reservation machine finishes uploading the recording data to the recording data storage server 3, the recording state of the recording reservation information management table 23 corresponding to the management ID is set to “Upload completed” in step S48 of FIG. (See also step S48 in FIG. 7).

  On the other hand, in the proxy requesting machine, in step S49 of FIG. 7, the recording processing unit 52 uses the recording reservation table 53 of its own apparatus to record a recording reservation with an identification ID with identification information “S” indicating that a recording request has been made. As for information, the recording state of the recording reservation information management table 23 is periodically searched using the management ID as a key. In step S50, the recording processing unit 52 of the substitution requesting machine acquires the recording state of the recording reservation information requested for substitution from the recording reservation information management server 2. In step S51, the recording processing unit 52 of the proxy requesting machine determines whether the recording state is upload completion. In the case of No in step S51, the recording processing unit 52 of the proxy request machine returns the process to step S49.

  On the other hand, in the case of Yes in step S51, in step S52, the recording processing unit 52 of the proxy requesting machine requests the recording data storage server 3 to download the recording data associated with the management ID. In step S <b> 53, the recording processing unit 52 of the proxy requesting machine downloads recording data from the recording data storage server 3. In step S54, the recording processing unit 52 of the proxy requesting machine notifies the user that the recording data has been downloaded, and ends the process.

  As described above, according to the present embodiment, when there is recording reservation information that overlaps the power failure time of the own device, the recorder 5 automatically registers the recording reservation information in the recording reservation information management server 2 and records the recording. Make a request. The other recorder 5 searches the recording reservation information registered in the recording reservation information management server 2, and if there is recording reservation information that does not overlap with its own power failure time and can be used for recording, the recording reservation information is displayed. It registers in the recording reservation table 53 of its own device and performs recording instead. Recorded data that has been recorded by another recorder 5 is uploaded to the recorded data storage server 3. The recorder 5 that has requested the recording downloads the recording data from the recording data storage server 3. Thereby, the user can acquire recording data by making a recording reservation with the recorder 5 of the own apparatus without worrying about the power failure time.

  In addition, according to the present embodiment, a dedicated agent reservation machine installed in advance throughout the country in order to specialize in agent reservation by performing a recording agent among the respective recorders 5 owned by users throughout the country, It is possible to efficiently cover the broadcasting networks in various parts of the country rather than having the recorder 5 act as a recording agent. Note that a plurality of recorders 5 serving as dedicated proxy reservation machines may be installed in advance as spares. In the present embodiment, each recorder 5 accesses the recording information reservation server 2 or the substitute recording data storage server 3 and specifies the recording reservation information or recording data using the management ID as a key. It is not necessary to store personal information for identifying each recorder 5 in the information reservation server 2 or the substitute recording data storage server 3, and it is not necessary to worry about leakage of personal information.

  In the above process, when the proxy requesting machine cancels the scheduled recording reservation information from the recording reservation table 53 of its own device by a user operation or the like, it refers to the recording reservation information management table 23 and corresponds to the management ID. Set the recording state of the recording reservation information to “cancel reservation”. Even when the blackout time does not overlap with the change of the blackout time and the substitution request becomes unnecessary, the recording state of the recording reservation information management table 23 is set to “reservation canceled” by the substitution requesting machine. Further, even when the substitution request machine changes the recording option of the recording reservation information requested for substitution by the user operation or the like, the recording state of the recording reservation information management table 23 is set to “cancel reservation”. In this case, the proxy requesting machine transmits the changed recording reservation information to the recording reservation information management server 2 anew. As a result, the recording reservation information after the change is newly registered in the recording reservation information management table 23 as the recording reservation information in which the management ID is allocated and the recording state is “searching for substitute reservation machine”.

  Further, the proxy reservation machine periodically searches the recording reservation information management table 23, and the recording reservation information of the recording reservation information of the identification ID with “R” or “W” in the recording reservation table 53 of its own device is recorded. If it is “reservation cancellation”, the recording reservation information of “R” is canceled from the recording reservation table 53 of the own apparatus, and the identification ID with “W” is deleted. In addition, the substitute reservation machine stores new recording reservation information in the recording reservation table 53 of its own device by a user operation or the like later in a time zone that overlaps the recording time zone of the recording reservation information of the identification ID with “R”. Suppose you register. In this case, the proxy reservation device cancels the recording reservation information with “R” from the recording reservation table 53 of the own device, and refers to the recording reservation information management table 23 to record the recording reservation information corresponding to the management ID. Is set to “searching for substitute reservation machine”, and the reservation reservation machine is returned to a state that has not been determined. Therefore, even if the recording reservation information of the proxy requesting machine is registered in the recording reservation table 53 of the proxy reservation machine, priority is given to the recording reservation of the proxy reservation machine itself.

  Further, when the user of the own device instructs the substitute reservation machine to reproduce the recording data corresponding to the recording reservation information with the identification ID “R” in the recording reservation table 53 of the own device, Since it is recorded data, it is notified that playback is not performed, and playback is prohibited, and the user is not allowed to view the recorded data. Further, the substitute reservation machine may not display the recording reservation information with “R” in the identification ID when instructed to display the recording reservation information by a user operation. This is because the recording reservation information with “R” in the identification ID is recorded for others, and it is not desirable for the user of the proxy reservation machine to view it from the viewpoint of copyright.

  In the above embodiment, only the recording reservation information that overlaps with the power failure time is substituted for the recording. However, the recording reservation information that overlaps between the recording apparatuses 5 may be represented on behalf of one recording apparatus 5. . In addition, when other recording reservation information is not registered in the recording reservation table 53 of the recording reservation information to be subjected to the substitute recording in the recording reservation table 53 of the recorder 5 serving as the substitute requesting machine, the recording time slot Alternatively, the power of the proxy requesting machine may be turned off to reduce power consumption.

  Further, in order to reduce the possibility of recording failure for some reason, it may be configured to perform proxy recording with two proxy reservation machines for one recording reservation information requested for proxy. In this case, the substitute reservation machine may determine whether or not substitute recording is possible for the recording reservation information whose recording state is “being searched for substitute reservation machine” or “one substitute reservation machine has been determined”. If the proxy recording is possible, the proxy reservation device registers the recording reservation information of the proxy requesting device in the recording reservation table 53 of its own device, and refers to the recording reservation information management table 23 to determine the recording state of the recording reservation information. It may be set to “one substitute reservation machine has been decided” or “two substitute reservation machines have been decided”.

  In addition, the proxy requesting machine informs the user that the recording reservation information requested by the proxy is in the process of searching for the proxy reservation machine even if a predetermined time before the power failure time (for example, 30 minutes before), etc. May be notified. At this time, when the recording option mismatch setting is “not allowed”, the recorder 5 changes the recording option mismatch setting to “allow” in order to make it easy to find a substitute reservation machine. The user may be prompted.

  Note that the recording processing unit 52 of the recorder 5 may allow the user to set a time for turning off the power of the recorder 5 regardless of the power failure time. In this case, the power-off time manually set by the user is also stored in the power failure time storage unit 54. The recording processing unit 52 also automatically sets recording reservation information for the recording reservation information registered in the recording reservation table 53 for the recording reservation information whose recording time zone overlaps the power OFF time stored in the power failure time storage unit 54. You may transmit to the information management server 2, and may perform the recording agent by the other recorder 5. FIG.

  In addition, the proxy reservation machine associates the CH of the recording reservation information of the proxy requesting machine with the broadcast station CH corresponding to the location of its own device or with the broadcast station capable of broadcasting in the postal code area. The determination may be made by referring to the registered broadcast station information table. The broadcast station information table may be provided in the recording information management server 2. In the broadcast station information table, each broadcast station is registered in units of the minimum broadcast station, and a key station, a semi-key station, and a local station in the broadcast area corresponding to the postal code are individually distinguished and registered. The proxy reservation machine refers to the broadcast station information table when determining whether it is the CH of the broadcasting station corresponding to the location area of the own device, and the CH of the broadcasting station broadcast in the area of the postal code of the own device. When it is, it may be determined that substitution is possible.

  In the above embodiment, each recording device 5 searches the recording reservation information management table 23 to determine whether or not its own device can be a substitute reservation device. It is also possible to search for the recorder 5 serving as a machine, determine a proxy reservation machine, and transmit the recorded data that is recorded on behalf of the proxy reservation machine to the proxy requesting machine. For example, the recording reservation information management server 2 periodically searches for the recording reservation information in the recording reservation information management table 23, and for the recording reservation information whose recording state is “searching for substitute reservation machine”, the Internet 4 is broadcasted, for example. Inquiries may be made to the recorders 5 as to whether they can serve as substitute reservation machines. In this case, the recording reservation information management server 2 has, for each recorder 5, whether the recording time zone overlaps with the power failure time, whether there is a recording CH in the program information, or the same manufacturer / same model number as the proxy requesting machine. In addition, it is only necessary to inquire about the processing performed to determine whether or not the recorder 5 can be a substitute reservation machine in the above-described embodiment, such as whether the recording options match. When the recording reservation information management server 2 finds a recorder 5 that can serve as a substitute reservation machine, it sends the recording reservation information of the substitute requesting machine to the recorder 5 and registers it in the recording reservation table 53 to manage the recording reservation information. The recording state of the table 23 is changed to “substitute reservation machine determined”. The recording reservation information management server 2 only has to acquire the recording data and transmit it to the proxy requesting machine when recording is performed by the proxy reservation machine in accordance with the recording reservation information of the proxy requesting machine. The recording reservation information management server 2 may take the lead as appropriate for the processing that each recorder 5 has otherwise performed. In this case, it is assumed that the recording reservation information management server 2 has the MAC address and IP address of each recorder 5 in advance.

  The present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the spirit of the present invention. For example, the power failure information management server 1, the recording reservation information management server 2, and the recording data storage server 3 may be configured as a single unit. Also, the recording reservation information management server 2 accepts the upload of the recording data from the substitute reservation machine, stores the uploaded recording data in the recording data storage server 3, and accepts the recording data download request from the substitute requesting machine. The recording data may be acquired from the recording data storage server 3 and transmitted to the proxy requesting machine. Note that, in the above-described embodiment, the same reference numerals are given to configurations showing similar functions.
