Description

  The present invention relates to a broadcast receiving device, a server, a communication system, and a reservation recording method, in particular, a broadcast receiving device that performs reservation recording in response to a request from a terminal, a server that performs processing related to reservation recording from a terminal to a device, and a terminal; The present invention relates to a communication system including a server and a broadcast receiving apparatus.

  The server provides program information to a terminal such as a mobile phone and transfers the reservation recording request from the mobile phone to a pre-registered device such as a digital terrestrial broadcasting receiver, thereby realizing reservation recording from outside the house. The service is embodied based on the technique disclosed in Patent Document 1.

  In this service, (1) a service user registers a device in advance and sets an area where the device is installed. (2) The server provides program information in the registered area. (3) Realized by selecting a program that a service user wants to record from program information provided from a server, and making a reservation recording request including the program date and time, CH (broadcast station) and title information to the device through the server is doing.

  Hereinafter, a method of realizing a service based on the technique described in Patent Document 1 will be described with reference to FIGS. 18 and 19.

  The communication system described in Patent Document 1 includes at least one device 1001 connected to the Internet 1005 via a router 1003, at least one terminal 1002 that can be connected to the Internet 1005, and the device 1001 and the terminal 1002 connected to the Internet 1005. And a server 1004 for transferring communication with the server.

  FIG. 18 is a diagram illustrating the operation of the conventional communication system described in Patent Document 1.

  First, the terminal 1002 transmits a program information acquisition request to the server 1004 based on the program information acquisition request from the user (S1001). Upon receiving the program information acquisition request from the terminal 1002, the server 1004 confirms the registration area (installation area) of the device 1001 linked to the terminal 1002 in advance (S1002). The server 1004 returns the program information viewable in the registered area to the terminal 1002 (S1003).

  The terminal 1002 that has received the program information from the server 1004 displays the received program information on a display unit (not shown). The user selects a program to be reserved for the device 1001 from the displayed program information (S1004). The terminal 1002 transmits a reservation recording request to the device 1001 via the server 1004 in accordance with a user instruction (S1005). The server 1004 that has received the reservation recording request from the terminal 1002 transfers the reservation recording request to the device 1001 associated with the terminal 1002 (S1006). The device 1001 that has received the timer recording request from the terminal 1002 via the server 1004 performs the timer recording registration process (S1007).

  FIG. 19 is a flowchart showing the flow of reserved recording registration processing (step S1007) by the device 1001. The device 1001 first analyzes the scheduled recording request data transmitted from the terminal 1002 (S1101). Next, the device 1001 determines whether the scheduled recording request data from the terminal 1002 is invalid (S1102). If the scheduled recording request data is invalid (Yes in S1102), the device 1001 ends the process. If the scheduled recording request data is correct (No in S1102), the device 1001 confirms whether the designated broadcast can be received (S1103). If it is not receivable (No in S1103), the device 1001 ends the process. If it can be received (Yes in S1103), the device 1001 confirms whether or not the scheduled recording can be executed at the designated time (S1104). If scheduled recording cannot be executed because another scheduled recording has already been registered or the like (No in S1104), the device 1001 ends the process. If the scheduled recording can be executed (Yes in S1104), the device 1001 performs a registration process for the scheduled recording request from the terminal 1002 (S1105), and ends the process.

  After the timer recording registration process (step S1007) is completed, the device 1001 returns a response indicating success or failure of the timer recording registration to the server (S1008). The server 1004 that has received the response from the device 1001 transfers the response to the terminal 1002 that has transmitted the timer recording request corresponding to the response (S1009). The terminal 1002 that has received the response analyzes the content of the response and shows the result to the user (S1010). Through these series of processes, the scheduled recording request from the terminal 1002 is registered in the device 1001.

On the other hand, mobile terminals such as mobile phones that receive low data rate broadcasts (hereinafter referred to as 1 segment broadcasts) of terrestrial digital broadcasts are beginning to be put on the market. With the advent of such portable terminals, it is assumed that viewing opportunities for television programs will increase. Furthermore, it is expected that the usage of recording a program being viewed on a mobile terminal with a digital terrestrial broadcasting receiver at home and watching it later on a large screen at home will increase in the future. In such a case, it is required to record a program being viewed on a portable terminal with a terrestrial digital broadcast receiver at home by a simple operation. For example, instead of selecting a program to be recorded from the program guide transmitted from the server as described above, by selecting a command such as “record the program being viewed” while viewing the program on the mobile terminal. Therefore, it is required to record on a digital terrestrial broadcast receiving apparatus at home.

  FIG. 4 is a block diagram illustrating a detailed configuration of the control unit 13. As shown in FIG. 4, the control unit 13 includes a request acquisition unit 131, a request analysis unit 132, a reception determination unit 133, a search unit 134, an update unit 135, and a scheduled recording registration unit 136.

  The request acquisition unit 131 acquires a reservation recording request from the terminal 2 via the network I / F 18.

  The request analysis unit 132 analyzes the reservation recording request acquired by the request acquisition unit 131 and determines whether or not the reservation recording request is illegal.

  The reception determination unit 133 determines whether the device 1 can receive the broadcast specified by the request acquired by the request acquisition unit 131.

  When the reception determining unit 133 determines that the designated broadcast cannot be received, the search unit 134 searches for a program that is receivable by the device 1 and that is the same as the designated program. Specifically, the search unit 134 obtains a request from a program included in the program information 191 stored in the SI information storage unit 19 when the reception determination unit 133 determines that the designated broadcast cannot be received. The program 131 includes information on the title of the program to be reserved recording included in the request acquired, and title information having a high degree of similarity with the information on the broadcasting date and time of the program. Search for programs.

  The updating unit 135 updates the information of the program that performs the reserved recording included in the reservation recording request acquired by the request acquisition unit 131 to the information of the program searched by the searching unit 134.

  The reserved recording registration unit 136 performs reserved recording based on the reservation recording request updated by the updating unit 135. That is, the scheduled recording registration unit 136 registers the scheduled recording of the program searched by the searching unit 134.

  Next, the operation of the communication system 100 according to Embodiment 1 of the present invention will be described.

  FIG. 5 is a diagram showing a processing sequence of the communication system 100 according to Embodiment 1 of the present invention. FIG. 5 is a diagram showing a processing sequence of the communication system 100 when a user tries to make a reservation recording of a program being viewed on the device 1 at home while the user is viewing the digital broadcast on the terminal 2. .

  As shown in FIG. 5, first, when the user is viewing the digital broadcast on the terminal 2 (S101), the user executes a reservation recording request for the program being viewed by a request unit (not shown). For example, the user selects a command such as “record the program being viewed” to execute a reservation recording request for the program being viewed. When the timer recording request is made by the user, the terminal 2 transmits the timer recording request to the device 1 via the server 4 (S102).

  FIG. 6 is a diagram illustrating an example of a configuration of a reservation request transmitted by the terminal 2.

  As shown in FIG. 6, the scheduled recording request includes a scheduled recording start date 211, a scheduled recording start time 212, a scheduled recording end time 213, a broadcast identifier 214, a program identifier 215, and a title (program) name 216. Including.

  The reserved recording start date 211 indicates the date on which the reservation is started. For example, when performing scheduled recording of a program being viewed on the terminal 2, the scheduled recording start date 211 is the current date or the like. The reserved recording start time 212 indicates the time at which reserved recording is started, and is, for example, the start time (or current time) of the program being viewed on the terminal 2. The scheduled recording end time 213 indicates a time at which the scheduled recording ends, and is, for example, an end time of a program being viewed on the terminal 2.

  The broadcast identifier 214 is an identifier for identifying a broadcast station or service, and network_id or service_id extracted from the received digital broadcast is used. For example, the broadcast identifier 214 is a 2-byte code uniquely assigned to each broadcast station or service.

  The program identifier 215 is an identifier for identifying a program, and event_id extracted from the received digital broadcast is used. For example, the program identifier 215 is a 2-byte code uniquely assigned to a program broadcast by each broadcasting station.

  The title name 216 is the title of the program that is scheduled to be recorded, for example, the title of the program that is being viewed on the terminal 2.

  The server 4 receiving the reservation recording request from the terminal 2 transfers the reservation recording request to the device 1 associated with the terminal 2 (S103). The device 1 that has received the timer recording request from the terminal 2 via the server 4 performs the following timer recording registration process (S104).

  FIG. 7 is a flowchart showing the flow of the reserved recording registration process for the device 1 in step S104.

  As shown in FIG. 7, the request acquisition unit 131 of the device 1 acquires a request for scheduled recording from the terminal 2, and the request analysis unit 132 analyzes the scheduled recording request data (S201). Next, the request analysis unit 132 determines whether the scheduled recording request data from the terminal 2 is invalid (S202). If it is illegal (Yes in S202), the control unit 13 ends the process. If the scheduled recording request data is correct (No in S202), the reception determining unit 133 determines whether the broadcast designated by the scheduled recording request is receivable (S203).

  When the designated broadcast cannot be received (No in S203), the search unit 134 sets the scheduled recording start time and the scheduled recording end time specified in the scheduled recording request from the program information 191 held by the SI information storage unit 19. The program information contained in is extracted (S204).

  FIG. 8 is a diagram illustrating an example of a scheduled recording request transmitted by the terminal 2. FIG. 8A is a diagram illustrating an example of a scheduled recording request acquired by the request acquisition unit 131. FIG. 8B is a diagram showing a reservation recording request after being updated by the control unit 13. For example, when the scheduled recording start time (ts-1) shown in the scheduled recording request shown in FIG. 8A is 16:00 and the scheduled recording end time (te-1) is 17:00, the detection unit 134 From the program information 191 shown in FIG. 3, program information having program identifiers ev-a1, ev-b1, and ev-n1 that are programs including broadcasting hours from 16:00 to 17:00 are extracted.

  The search unit 131 further performs a match search between the title (program) name 216 included in the reservation recording request and the program title 205 extracted from the program information 191 (S205). That is, a matching search is performed between the title name (tittle-1) shown in the reservation recording request shown in FIG. 8A and the titles of extracted programs, title-a1, title-b1, and title-n1. If there is no title that matches the title (tittle-1) specified by the reservation recording request (No in S206), the control unit 13 ends the reservation recording registration process. If there is a matching title (Yes in S206), the updating unit 135 performs an update process for the scheduled recording request received from the terminal 2 (S207). For example, if it is determined that the title (tittle-1) designated by the scheduled recording matches the title-b1 in the broadcast B, the scheduled recording request information shown in FIG. As shown in FIG. 5, the title 205 in the broadcast B is updated based on the information of the program whose title-b1 is title-b1. With these processes, even if the broadcast station requested for reservation recording from the terminal 2 cannot be received by the device 1, if the same program is being broadcast by another broadcast station that can be received by the device 1, the reservation recording is performed. It becomes possible.

  When the broadcast designated by the reserved recording is receivable (Yes in S203), or after performing the above-described reserved recording request update process (step S207), the reserved recording registration unit 136 requests or updates the reserved recording. It is confirmed whether or not the scheduled recording can be executed at the time designated by the reserved recording request (S208). If the reserved recording cannot be executed because another reserved recording has already been registered (No in S208), the control unit 13 ends the process. When the reservation recording registration unit 136 determines that the reservation recording can be executed (Yes in S208), the reservation recording registration unit 136 performs the reservation recording request from the terminal 2 or the registration processing of the updated reservation recording request. This is performed (S209). Thus, the device 1 ends the reserved recording registration process.

  The device 1 that has completed the reserved recording registration process (step S104) returns a response indicating success or failure of the reserved recording registration to the server (S105). The server 4 that has received the response from the device 1 transfers the response to the terminal 2 that has transmitted the timer recording request corresponding to the response (S106). The terminal 2 that has received the response analyzes the content of the response and shows the result to the user (S107). Through these series of processes, the reservation recording request from the terminal 2 is registered in the device 1.

  As described above, when the device 1 of the communication system according to the first embodiment of the present invention cannot receive the broadcast specified by the reservation recording request transmitted from the terminal 2, the program information held by the device 1 is stored. On the other hand, the program corresponding to the program specified from the terminal 2 is searched by searching by the title name of the program to be reserved recording included in the reservation recording request. Thus, the communication system according to Embodiment 1 of the present invention is a case where the broadcast station of the program that the user is watching on the terminal 2 cannot be received by the device 1 installed at home, and the scheduled recording request When the same program is broadcast on a different broadcast station, it is possible to make a reservation recording.

  In addition, when the device 1 of the communication system according to the first embodiment of the present invention cannot receive the broadcast specified by the reservation recording request transmitted from the terminal 2, the program 1 holds the program information held by the device 1. Thus, a program with the same or similar information on the date and time of the program to be scheduled recording included in the scheduled recording request is extracted, and the extracted program is searched by the title name. Thereby, the processing amount of the program search in the apparatus 1 can be reduced. Even when a plurality of programs having the same title are included in the program information, a correct program can be extracted.

  In step S205, the search unit 134 performs a search based on the title (program) name information included in the reservation recording request, but in addition to the title (program) name information included in the reservation recording request, for each affiliated station. You may search from the grouped information. In this case, the device 1 holds broadcast station information that is information on a broadcast station included in the affiliated station. For example, the SI information storage unit 19 or the broadcast station information storage unit not shown holds the broadcast station information.

  FIG. 9 is a diagram illustrating an example of broadcast station information. The broadcast station information shown in FIG. 9 includes information of broadcast stations classified into groups 1 to G of a plurality of affiliate stations. For example, group 1 includes broadcast 1.1 to broadcast 1. z broadcast stations of z are included. For example, the broadcast station information is a 2-byte code uniquely assigned to each broadcast station or service using network_id or service_id extracted from the received digital broadcast.

  The search unit 134 is included in the same affiliated station as the program that performs reserved recording based on the broadcast station information from the programs included in the program information 191 stored in the SI information storage unit 19 and acquired by the request acquisition unit 131. A program having title information that matches the title information of the program to be reserved for recording included in the request is searched. That is, when the device 1 receives the reservation recording request from the terminal 2 and the broadcast station designated by the recording request cannot be received, the device 1 is in the same group as the designated broadcast station and the device 1 can receive the broadcast station. Program information is extracted from the SI information storage unit 19. The search unit 134 performs a match search between the title (program) name information included in the reservation recording request and the title information in the program information of the broadcast station in the same group as the designated broadcast station. As a result, it is possible to narrow down the matching search targets. Further, in national broadcasting or the like, it is possible to extract the same program that can be received by the device 1 in response to a reservation recording request from the terminal 2 with less matching search processing.

  In step S205, the title match search is performed based on whether the titles match. However, it is possible to determine the title similarity and extract a program with a high similarity. For example, if the service provider providing program information is different between the terminal 2 and the device 1, description of the titles of the scheduled recording request information transmitted by the terminal 2 and the program information held by the device 1 May be different. In step S205, it is possible to determine the desired program even if the reserved video recording request information transmitted by the terminal 2 and the program information held by the device 1 do not completely match by determining the title similarity. Can be searched. Further, when a plurality of candidate titles are extracted by determining the similarity of the titles, the search condition is set to at least one of the program start date, start time, and end time for the extracted titles. Further, narrowing down may be performed.

  Further, in narrowing down the programs by the broadcast time in the above step S204, the broadcast time of the program (the reserved recording start time 212 to the reserved recording end time 213) specified by the reserved recording request transmitted from the terminal 2 is the broadcast time (program Although the program included in the start time 202 to the end time 203) of the information 191 is extracted, the present invention is not limited to this. For example, a part of the broadcast time of the program specified in the reservation recording request may be extracted as a program included in the broadcast time, or within a predetermined time before and after the broadcast time of the program specified in the reservation recording request You may extract the program broadcast on. Furthermore, the program information 191 may include information on the start date of the program, and a program having information on the start date of the program that matches or is similar to the recording start date 211 of the scheduled recording request may be extracted.

  In steps S204 to S205, the search by title name is performed after narrowing down by date and time. However, the search by title name may be performed without narrowing down by date and time. Further, when a plurality of candidates are extracted by a search by title name, a search by date and time may be performed.

(Embodiment 2)
In the first embodiment described above, the communication system in which the device 1 updates the reservation recording request has been described. In Embodiment 2 of the present invention, a communication system in which a server updates a reservation recording request will be described.

  The schematic configuration of the communication system according to the second embodiment is the same as that of the first embodiment (FIG. 1), and thus the description thereof is omitted. The schematic configuration of the device 1 is the same as that shown in FIG. In the second embodiment, the control unit 13 of the device 1 may not include the request analysis unit 132, the reception determination unit 133, the search unit 134, and the update unit 135 illustrated in FIG.

  FIG. 10 is a block diagram showing a schematic configuration of the communication system according to the second embodiment. The server 4 shown in FIG. 10 includes a control unit 43, a network I / F 48, and an SI information storage unit 49.

  The network I / F 48 receives a request from an external device (for example, the device 1 or the terminal 2) connected to the Internet 5 and notifies the control unit 43 of the request. Further, the network I / F 48 transmits data such as a request to an external device connected to the Internet 5 under the control of the control unit 43.

  The SI information storage unit 49 holds program information 491 including information on programs that can be received by the device 1. For example, the program information 491 has the configuration shown in FIG. 3 as in the first embodiment. Note that the program information 491 held by the SI information storage unit 49 includes program information of other regions according to the range of services provided by the server 4. For example, if the service provided by the server 4 is all regions in Japan, the SI information storage unit 49 holds program information broadcasted throughout Japan.

  The control unit 43 performs overall control of the server 4. Further, the control unit 43 updates the reservation recording request transmitted from the terminal 2. The control unit 43 includes a request acquisition unit 431, a request analysis unit 432, a reception determination unit 433, a search unit 434, an update unit 435, and a request transmission unit 436.

  The request acquisition unit 431 acquires a reservation recording request from the terminal 2 via the network I / F 48.

  The request analysis unit 432 analyzes the reservation recording request acquired by the request acquisition unit 432 and determines whether or not the reservation recording request is illegal.

  The reception determination unit 433 determines whether the device 1 can receive the broadcast specified by the request acquired by the request acquisition unit 432.

  When the reception determination unit 433 determines that the designated broadcast cannot be received, the search unit 434 searches for a program that can be received by the device 1 and that is the same as the designated program. Specifically, the search unit 434 can receive the device 1 included in the program information 491 stored in the SI information storage unit 49 when the reception determination unit 433 determines that the designated broadcast cannot be received. Broadcast date and time having a title information that matches the title information of the program to be reserved recording included in the request acquired by the request acquisition unit 432 and having high similarity to the broadcast date and time information of the program. The program having the information is searched.

  The update unit 435 updates the information of the program to be reserved recording included in the reservation recording request acquired by the request acquisition unit 431 to the information of the program searched by the search unit 434.

  The request transmission unit 436 transmits the reservation recording request updated by the update unit 435 to the device 1 via the network I / F 48.

  Hereinafter, the operation of the communication system according to Embodiment 2 of the present invention will be described.

  FIG. 11 is a diagram showing a processing sequence of the communication system according to Embodiment 2 of the present invention. FIG. 11 is a diagram showing a processing sequence of the communication system when a user attempts to make a reservation recording of a program being viewed on the device 1 at home while the user is viewing the digital broadcast on the terminal 2.

  As shown in FIG. 11, first, when the user is viewing a digital broadcast on the terminal 2 (S301), the user executes a reservation recording request for the program being viewed by request means (not shown). For example, the user selects a command such as “record the program being viewed” to execute a reservation recording request for the program being viewed. When the timer recording request is made by the user, the terminal 2 transmits the timer recording request to the server 4 (S302). The scheduled recording request transmitted by the terminal 2 is the same as that in the first embodiment, and has the configuration shown in FIG. 6, for example.

  The server 4 that has received the timer recording request from the terminal 2 performs the timer recording request update process based on the registration information of the device 1 associated with the terminal 2 (S303).

  FIG. 12 is a flowchart showing the flow of the scheduled recording update process of the server 4 in step S303.

  The request acquisition unit 431 of the server 4 acquires a reservation recording request from the terminal 2, and the request analysis unit 432 analyzes reservation recording request data (S401). Next, the request analysis unit 432 determines whether the scheduled recording request data from the terminal 2 is invalid (S402). If it is illegal (Yes in S402), the server 4 ends the process. If the scheduled recording request data is correct (No in S402), the reception determination unit 433 determines whether the device 1 associated with the terminal 2 can receive the broadcast designated by the scheduled recording request (S403). . The server 4 determines whether or not the device 1 can receive the designated broadcast based on the installation area information of the device 1 registered in advance or broadcast station information that the device 1 can receive.

  When the device 1 cannot receive the designated broadcast (No in S403), the search unit 434 is a program of a broadcasting station that can be received by the device 1 linked to the terminal 2 from the program information storage unit 191, and Information of the program included in the reserved recording start time and the reserved recording end time specified in the reserved recording request is extracted (S404). For example, as in the first embodiment, the reserved recording start time (ts-1) shown in the recording request shown in FIG. 8A is 16:00, and the reserved recording end time (te-1) is 17:00. The search unit 434 extracts programs whose program identifiers are ev-a1, ev-b1, and ev-n1, which are programs including broadcasting hours from 16:00 to 17:00, from the program information 191 shown in FIG.

  The search unit 433 further performs a match search between the title (program) name 216 included in the reservation recording request and the title 205 of the extracted program (S405). That is, a matching search is performed between the title name (tittle-1) indicated in the reservation recording request shown in FIG. 8 and titles of title-a1, title-b1, and title-n1 that are extracted program information titles. When there is no title that matches the title (tittle-1) specified by the reservation recording request (No in S406), the server 4 ends the reservation recording request update process. If there is a matching title (Yes in S406), the updating unit 435 performs an update process for the scheduled recording request received from the terminal 2 (S407). For example, when it is determined that the title (tittle-1) designated by the scheduled recording matches the title-b1 in the broadcast B, the update unit 435 updates the scheduled recording request information shown in FIG. As shown in FIG. 8B, updating is performed based on the program information whose title in broadcast B is title-b1. With these processes, even if the broadcasting station requested by the reservation recording from the terminal 2 cannot be received by the device 1, if the same program is being broadcast by another broadcasting station that can be received by the device 1, the program is extracted. It becomes possible to do.

  When the device 1 can receive the broadcast designated by the scheduled recording, or after performing the above-described scheduled recording request update process, the request transmission unit 436 requests the scheduled recording or updates the scheduled recording as described above. Transfer the request to the device 1. Although not shown, if the request data is invalid (Yes in S402) or there is no matching title (No in S406), the request transmission unit 436 does not transfer the scheduled recording request to the device 1 and an error occurs. Information indicating that it occurred (cannot be scheduled recording) is transmitted to the terminal 2.

  After completing the reservation recording request update process (step S303), the server 4 transfers the reservation recording request to the device 1 associated with the terminal 2 (S304). The device 1 that has received the timer recording request from the terminal 2 via the server 4 performs the timer recording registration process (S305). Here, since the reservation recording request received by the device 1 is updated by the server 4 to broadcast information that can be received by the device 1, the device 1 can normally perform the reservation recording registration process.

  The device 1 returns a response indicating success or failure of the reserved recording registration to the server 4 after the reservation recording registration process is completed (S306). The server 4 that has received the response from the device 1 transfers the response to the terminal 2 that has transmitted the timer recording request corresponding to the response (S307). The terminal 2 that received the response analyzes the content of the response and shows the result to the user (S308). Through these series of processes, the reservation recording request from the terminal 2 is registered in the device 1.

  As described above, the server 4 of the communication system according to Embodiment 2 of the present invention holds the server 4 when the device 1 cannot receive the broadcast specified by the reservation recording request transmitted from the terminal 2. The program corresponding to the program designated from the terminal 2 and receivable by the device 1 by searching the program information by the title name of the program to be scheduled recording included in the scheduled recording request. To extract. The server 4 updates the reservation recording request based on the extracted program and transmits it to the device 1. As a result, the communication system according to Embodiment 2 of the present invention is a case where the broadcast station of the program that the user is watching on the terminal 2 cannot be received by the device 1 installed at home, and the scheduled recording request When the same program is broadcast on a different broadcast station, it is possible to make a reservation recording.

  In addition, the server 4 of the communication system according to the second embodiment of the present invention holds the server 1 when the device 1 cannot receive the broadcast specified by the reservation recording request transmitted from the terminal 2. For the program information, a program having the same or similar information on the date and time of the program to be reserved recording included in the reservation recording request is extracted, and the extracted program is searched for by title name. Thereby, the processing amount of the program search in the server 4 can be reduced. Even when a plurality of programs having the same title are included in the program information, a correct program can be extracted.

  In the communication system according to the second embodiment of the present invention, when the device 1 cannot receive the broadcast of the program that the user is watching on the terminal 2, the server 4 updates the reservation recording request. As a result, the same program is broadcast on other broadcast stations even when the broadcast station requested for reservation recording from the terminal 2 cannot be received without adding functions and increasing the processing amount to the device 1. If so, it is possible to make a scheduled recording.

  In step S405, the search unit 434 performs a search based on the title (program) name information included in the reservation recording request, but in addition to the title (program) name information included in the reservation recording request, for each affiliated station. You may search from the grouped information. In this case, the server 4 holds broadcast station information that is information on the broadcast stations included in the affiliated stations. For example, the SI information storage unit 49 or the broadcast station information storage unit not shown holds the broadcast station information. The server 4 holds, for example, broadcast station information shown in FIG. The search unit 434 is included in the same affiliated station as the program that performs reserved recording based on the broadcast station information, and is acquired by the request acquisition unit 431 from the programs included in the program information 491 stored in the SI information storage unit 49. A program having title information that matches the title information of the program to be reserved for recording included in the request is searched. That is, the server 4 holds information grouped for each affiliated station, receives a reservation recording request from the terminal 2, and the device 1 linked with the terminal 2 cannot receive the broadcast station specified by the recording request. In this case, program information of broadcast stations that are in the same group as the designated broadcast station and can be received by the device 1 may be extracted from the program information storage unit. The title (program) name information included in the reservation recording request is matched with the title information in the program information of the broadcasting stations in the same group as the designated broadcasting station. As a result, it is possible to narrow down the matching search targets. Further, in national broadcasting or the like, it is possible to extract the same program that can be received by the device 1 in response to a reservation recording request from the terminal 2 with less matching search processing.

  The search unit 134 searches for the same program as the designated program. Specifically, it is a program of a broadcast station of a program that performs reserved recording included in the request acquired by the request acquisition unit 131 from the programs included in the program information 191 stored in the program information storage unit 19, and the request The acquisition unit 131 searches for a program having title information that matches the title information of the program to be reserved for recording included in the request acquired.

  The updating unit 135 updates the information of the program that performs the reserved recording included in the reservation recording request acquired by the request acquisition unit 131 to the information of the program searched by the searching unit 134.

  The reserved recording registration unit 136 performs reserved recording based on the reservation recording request updated by the updating unit 135. That is, the scheduled recording registration unit 136 registers the scheduled recording of the program searched by the searching unit 134.

  The operation of the communication system according to Embodiment 3 of the present invention will be described below.

  FIG. 15 is a diagram showing a processing sequence of the communication system according to Embodiment 3 of the present invention. FIG. 15 is a diagram showing a processing sequence of the communication system when a user attempts to make a reservation recording of the program being viewed on the device 1 at home while the user is viewing the digital broadcast on the terminal 2.

  As shown in FIG. 15, first, at the terminal 2, when the user is viewing a digital broadcast (S501), the user executes a reservation recording request for the program being viewed by a request unit (not shown). For example, the user selects a command such as “record the program being viewed” to execute a reservation recording request for the program being viewed. When the timer recording request is made by the user, the terminal 2 transmits the timer recording request to the server 4 (S502). In the third embodiment, the scheduled recording request transmitted by the terminal 2 includes a scheduled recording start date 201, a scheduled recording start time 202, a scheduled recording end time 203, a broadcast station identifier 204, a title (program) name 206, and the like. including. That is, the difference from Embodiment 1 and Embodiment 2 is that the scheduled recording request does not include the program identifier 205. The program identifier 205 included in the reservation recording request may be blank data.

  The server 4 that has received the timer recording request from the terminal 2 performs the timer recording request update process based on the registration information of the device 1 associated with the terminal 2 (S503).

  FIG. 16 is a flowchart showing the flow of the scheduled recording request update process of the server 4 in step S503.

  As shown in FIG. 16, the request acquisition unit 431 of the server 4 acquires a reservation recording request from the terminal 2, and the request analysis unit 432 analyzes the reservation recording request data from the terminal 2 (S601). Next, the request analysis unit 432 determines whether the scheduled recording request data from the terminal 2 is invalid (S602). If it is illegal (Yes in S602), the control unit 43 ends the process. If the scheduled recording request data is correct (No in S602), the reception determination unit 433 determines whether the device 1 associated with the terminal 2 can receive the designated broadcast by the scheduled recording request (S603). ). The reception determination unit 433 determines whether or not the device 1 can receive the designated broadcast based on the installation area information of the device 1 registered in advance or the broadcast station information that the device 1 can receive. .

  When the device 1 cannot receive the designated broadcast (No in S603), the update unit 435 updates the broadcast identifier 204 included in the reservation recording request (S604). Specifically, the search unit 434 uses a broadcast station corresponding to the broadcast identifier transmitted from the terminal 2 based on the broadcast station information 501 held by the broadcast station information holding unit 50 and the installation area information of the device 1. A broadcast station that is a broadcast station of the affiliated station and that can be received by the device 1 is searched. The update unit 435 updates the broadcast identifier transmitted from the terminal 2 to the broadcast identifier of the broadcast station searched by the search unit 434.

  When the device 1 can receive the broadcast designated by the scheduled recording, or after performing the above-described scheduled recording request update process, the request transmission unit 436 requests the scheduled recording or updates the scheduled recording as described above. Transfer the request to the device 1. Although not shown, when the request data is invalid (Yes in S602), the request transmission unit 436 does not transfer the scheduled recording request to the device 1 and an error has occurred (scheduled recording cannot be performed). Is transmitted to the terminal 2.

  After completing the reservation recording request update process, the server 4 transfers the reservation recording request to the device 1 associated with the terminal 2 (S504). The device 1 that has received the timer recording request from the terminal 2 via the server 4 performs the timer recording registration process (S505).

  FIG. 17 is a flowchart showing the flow of the reserved recording registration process for the device 1 in step S505.

  As illustrated in FIG. 17, the request acquisition unit 131 of the device 1 acquires the reservation recording request transferred by the server 4, and the request analysis unit 132 analyzes the acquired reservation recording request (S <b> 701). Next, the search unit 134 extracts the program information of the broadcast station identifier specified by the reservation recording request updated by the server 4 from the program information 191 held by the SI information storage unit 19 (S702). For example, when the broadcast station identifier 214 of the reservation recording request is sid-b, the search unit 134 is a program of broadcast B whose broadcast identifier (service ID) is sid-b with respect to the program information 191 shown in FIG. A program whose program identifier is ev-b1, ev-b2, ev-b3, ev-b4, etc. is extracted.

  The search unit 134 further searches for a match between the title (program) name 216 included in the reservation recording request and the title 205 of the extracted program (S703). For example, when the scheduled recording request shown in FIG. 8A is transmitted from the server 4, broadcast B programs such as title-1 and title-b1, title-b2, title-b3, title-b4, etc. Is searched for a match with the title 205. When there is no program with a title that matches the title name 216 specified by the reservation recording request (No in S704), the control unit 13 ends the reservation recording registration process. If there is a matching title (Yes in S704), the updating unit 135 performs an update process for the received scheduled recording request (S705). For example, when it is determined that the title (tittle-1) designated by the scheduled recording matches the title-b1 in the broadcast B, the update unit 135 changes the scheduled recording request information shown in FIG. As shown in FIG. 8B, the program information of the title-b1 in the broadcast B is updated. In Embodiment 3 of the present invention, the scheduled recording request transmitted from the terminal 2 does not include the program identifier 215, or the program identifier 215 is blank data, and the scheduled recording request update process by the device 1 is performed. In (step S705), the program identifier 215 is added or updated based on the search result. With these processes, even if the broadcast station requested for reservation recording from the terminal 2 cannot be received by the device 1, if the same program is being broadcast by another broadcast station that can be received by the device 1, the reservation recording is performed. It becomes possible.

  After performing the reservation recording request update process (step S705), the reservation recording registration unit 136 confirms whether the reservation recording can be executed at the time designated by the updated reservation recording request (S706). If the reserved recording cannot be executed because another reserved recording has already been registered (No in S706), the control unit 13 ends the process. If the reservation recording registration unit 136 determines that the reservation recording can be executed (Yes in S706), the reservation recording registration unit 136 performs an updated reservation recording request registration process (S707). Thus, the device 1 ends the reserved recording registration process (step S505).

  After the reservation recording registration process (step S505) ends, the device 1 returns a response indicating success or failure of the reservation recording registration to the server 4 (S506). The server 4 that has received the response from the device 1 transfers the response to the terminal 2 that has transmitted the timer recording request corresponding to the response (S507). The terminal 2 that received the response analyzes the content of the response and shows the result to the user (S508). Through these series of processes, the reservation recording request from the terminal 2 is registered in the device 1.

  In step S702, the control unit 13 of the device 1 extracts the program from the broadcast station identifier updated by the server 4. However, in addition to the broadcast station identifier, information on the date and time of the program included in the reserved recording request A program may be extracted from (reserved recording start date, reserved recording start time, and reserved recording end time).

  As described above, the server 4 of the communication system according to Embodiment 3 of the present invention holds the server 4 when the device 1 cannot receive the broadcast specified by the reservation recording request transmitted from the terminal 2. The broadcast station identifier of the program designated by the terminal 2 is the broadcast station of the same series as the broadcast station of the program designated by the terminal 2 from the information of the affiliated station of the broadcast station, and the device 1 can receive the broadcast station. Update to broadcasting station identifier. The device 1 extracts a program based on the broadcast identifier updated by the server 4 and selects a program with a title that matches or is similar to the title information included in the scheduled recording request transmitted from the terminal 2 for the extracted program. To do. The device 1 performs the reserved recording of the selected program so that the broadcast station of the program that the user is watching on the terminal 2 cannot be received by the device 1 installed at home, and the reservation recording request When the same program is broadcast on different broadcasting stations, it becomes possible to perform scheduled recording. Further, since the search process in the device 1 is performed for a program of a broadcast station in the same series as the broadcast station of the program designated from the terminal 2, the processing amount of the device 1 can be reduced.

  In the communication system according to Embodiment 3 of the present invention, the title search is performed regardless of whether or not the program designated by the reservation recording request is receivable by the device 1, and the designated program ( Alternatively, the program identifier of the program corresponding to the designated program is specified. Therefore, the terminal 2 does not have to transmit the program identifier 205 as a reservation recording request. Thereby, since the terminal 2 does not need to hold | maintain or acquire the information of the program identifier 205, the processing amount of the terminal 2 can be reduced.

  In the device 1, reservation recording can be performed from the reservation recording start time and reservation recording end time transmitted from the terminal 2 and the broadcast identifier updated by the server 4 without performing a search by title. This is because in national broadcasting and the like, corresponding programs are often broadcast at the same time between broadcasting stations of the same affiliated station. However, in the case where the device 1 does not search by title, it cannot respond when the broadcast time of the corresponding program differs between broadcast stations of the same affiliated station. In addition, when the broadcast time of a program is changed due to an extension of a sports broadcast program or the like, the program for the changed time cannot be recorded unless the program identifier is specified. On the other hand, as described above, by searching by title and specifying a program identifier, if the broadcast time of the corresponding program differs between broadcast stations of the same affiliated station, and the change of the broadcast time of the program Even if there is, you can record correctly.

  The present invention can be applied to a broadcast receiving device, a server, and a communication system, and particularly includes a terrestrial digital broadcast receiving device and a terminal such as a mobile phone having a one-segment broadcast receiving function and a communication function. The present invention can be applied to a communication system that performs scheduled recording on an apparatus.
