The communication unit 251 includes a communication protocol such as TCP / IP and UDP / IP, and communicates with a device on the network 50.

The control unit 252 may include a CPU function, recognizes an instruction from an instruction signal received from a device on the network 50 via the communication unit 251, and based on the instruction, performs various functional units of the search server device 25. Control. Further, the control unit 252 outputs the data output by the various functional units to the communication unit 251. For example, when the control unit 252 receives the program information search request signal including the search keyword from the receiving device 10 and acquires the program information search request command, the control unit 252 controls the function of the search server device 25 to search the program information. Execute.

The request processing unit 253 receives an instruction from the control unit 252 and executes the instruction. When the request processing unit 253 receives the program information search request command from the control unit 252, the request processing unit 253 outputs the program identification information such as the program name of the content included in the program information search request command to the search unit 250 to request the search. do.

The data storage unit 254 is, for example, a hard disk, and may store search results such as CSP program information searched by the search unit 250. The data storage unit may be outside the content server device 21.

FIG. 5B is an example of CSP program information stored in the data storage unit 254, and the CSP program information is a search result by the search unit 250. The data 2351 shows the CSP of the content server device 23 that provides the broadcast program for each broadcast program broadcast by the broadcast signal. For example, the data 252 indicates a URL in which the CSPs providing the program 32, which is a broadcast program, are the CSP1 and the CSP8, and are the access destinations of the CSP1 and the CSP8. The program 11 and the program 32 may be a program name or program identification information as long as the program can be specified.

When the data output unit 255 receives the search keyword such as the program identification information, the data output unit 255 acquires the CSP program information related to the search keyword from the data storage unit 254 and outputs the CSP program information to the control unit 252. The control unit 213 outputs CSP program information to the request source.

6A and 6B are functional block diagrams showing a configuration example of a database device according to an embodiment, FIG. 6A is a functional block diagram of the database device, and FIG. 6B is a database of a data storage unit 305 which is a storage medium of the database device. It is a figure which showed the outline of.

The database device 30 acquires content program information that can be provided by the content server device 23 from the content server device 23 on the network 50. Since the content server device 23 does not have a function for searching content from the outside, the content server device 23 transmits the content program information to the database device 30 in response to a request, spontaneously, or periodically. The database device 30 stores the received content program information in the data storage unit 305.

The communication unit 301 includes a communication protocol such as TCP / IP and UDP / IP, and communicates with a device on the network 50.

The control unit 302 may include a CPU function, recognizes an instruction from an instruction signal received from a device on the network 50 via the communication unit 301, and controls various functional units of the database device 30 based on the instruction. do. Further, the control unit 302 outputs the data output by the various functional units to the communication unit 301.

The request processing unit 303 receives an instruction from the control unit 302 and executes the instruction. When the request processing unit 303 receives the program information request command from the control unit 302, the request processing unit 303 outputs the program identification information such as the program name of the content included in the program information request command to the search unit 304 and makes a search request. ..

When the search unit 304 receives the search request from the request processing unit 303 together with the program identification information such as the program name of the content, the search unit 304 may search the database of the data storage unit 305 for the CSP that provides the content related to the program identification information. The search unit 304 provides the content requested to be searched, but when the CSP is found, the search unit 304 generates CSP program information including the name of the CSP provider and the URL which is the access information to the content. The search unit 304 outputs CSP program information to the request processing unit 303.

The data storage unit 305 is, for example, a hard disk, and may store content program information for each CSP received from the content server device 23 on the network 50, a catalog related to the program information, and the like. The data storage unit may be outside the content server device 21.

When the data providing unit 306 receives the program information provision request, the data providing unit 306 acquires the CSP program information related to the content requested to be provided from the database of the data storage unit 305 and outputs the CSP program information to the control unit 302. The control unit 302 outputs CSP program information to the program information requester.

The data update unit 307 receives, for example, content program information spontaneously or periodically transmitted from the content server device 23 on the network 50, and updates the database of the data storage unit 305.

FIG. 6B shows an example of the database of the data storage unit 305. In the figure, data related to CSP8, CSP7, and CSP3, which are CSP providers, are stored as data 3051, 3052, and 3053, respectively. For example, the data 3053 includes content program information of the content provided by the CSP 3, information related to the content such as the program name and URL of the content. Further, when the content provided by the CSP 3 includes the content of the broadcast program provided by the digital broadcast, the channel, the broadcast time, and the like in the digital broadcast may be further included in the CSP program information.

Hereinafter, an operation example when the receiving device according to the embodiment generates and updates EPG information data for displaying program information on the display unit 151 will be shown.

The EPG information is data for generating display program information, and includes broadcast program information, CSP program information, content program information, recorded data, and the like. Broadcast program information is acquired by the broadcast program information acquisition unit 101. The CSP program information and the content program information are acquired by the CSP program information acquisition unit 102, the DB program information acquisition unit 103, the network data processing unit 16, and the like. The recorded data is managed by the recorded data management unit 104.

FIG. 7 is a flowchart showing a processing operation example when the receiving device according to the embodiment updates the CSP program information, and the receiving device voluntarily or periodically obtains the CSP program information by the program of the receiving device or the like. This is an example of a flowchart when settings such as performing are set. For example, the remote controller 100 may be provided with an update button, and the user may press the update button to update the CSP program information.

The control unit 18 acquires broadcast program information from the broadcast program information acquisition unit 101 (step S11). The broadcast program information acquisition unit 101 may spontaneously acquire broadcast program information from the broadcast signal and update it while the broadcast signal acquisition unit 11 is receiving the broadcast signal. The control unit 18 determines whether or not there is a CSP provider (providing the content server device 21 or the content server device 23) that provides the broadcast program now or in the future on the network for the broadcast program included in the acquired broadcast program information. Is confirmed (steps S12 to S24). For example, the broadcast program A1 will be described as an example of one of the broadcast programs included in the broadcast program information. The user can select the CSP provider for which the program information is to be confirmed. Steps S12 and S24 indicate that steps S13 to S23 are executed for all the target broadcast programs.

FIG. 8 is a diagram showing an example of a selection screen for selecting a CSP provider to be confirmed for content program information, which is displayed by the receiving device according to the embodiment.

The display frame 601 is a setting portion for CSP 1, and similarly, settings for each CSP provider (CSP 2 to CSP 5) can be set for each line. The display frame 602 is a check box for the user to select whether or not to confirm the content program information of the CSP provider of each line, and when the corresponding CSP provider is enabled, the user is applicable. Check the check box of the line to be used. FIG. 8 shows an example of acquiring content program information from a CSP provider other than CSP3. The display frame 603 indicates the name of the CSP provider of each line. The display frame 604 indicates a button for changing the display order of the CSP provider on the selection screen. The display frame 605 shows the setting status of the access account to the server provided by the CSP provider of each line. FIG. 8 shows an example in which a user's access account to other than CSP3 is set. The display frame 606 indicates a scroll bar for scrolling the display of the selection screen (display frame 602 to display frame 605). In FIG. 8, only CSP1 to CSP5 are displayed, but other CSP providers are also set, and the display can be performed by scrolling.

Returning to step 13 of FIG. 7, the control unit 18 confirms whether or not the CSP provider checked in the display frame 602 of the selection screen of FIG. 8 is providing the content including the content of the broadcast program A. As one of the CSP providers to be confirmed, CSP1 will be described as an example. Steps S13 and S19 indicate that steps S14 to S18 are executed for all target CSP providers.

The control unit 18 confirms whether or not the CSP1 provides the search function (step S14). Normally, the CSP provider that provides the search function provides dedicated software called WebAPI, and if the receiving device 10 has the WebAPI of the corresponding CSP provider installed, the corresponding CSP provider searches. You can determine if you are providing a feature. When the CSP 1 provides the search function (corresponding to the case where the CSP 1 provides the content server device 21), the control unit 18 outputs a search request command to the CSP 1 to the CSP program information acquisition unit 102. do. Upon receiving the search request command to CSP1, the CSP program information acquisition unit 102 outputs a search request to CSP1 (YES in step S14, step S15).

More specifically, the search request is included in the search request signal by the network data processing unit 16, and is output from the communication unit 191 to the content server device 21 of the CSP1 via the network 50. Upon receiving the search request, the content server device 21 of the CSP 1 searches the data storage unit 211 for content including the content of the broadcast program A, and transmits the search result to the receiving device 10. In the receiving device 10, the CSP program information acquisition unit 102 receives the search result and confirms the search result. As a result of checking the search result, if the CSP1 can provide the content including the content of the broadcast program A, the CSP program information acquisition unit 102 associates the CSP1 with the broadcast program A and CSP program information of the broadcast program A. Is updated (step S18).

If a CSP provider capable of providing content including the contents of the broadcast program A is found, steps S14 to S18 may be executed for the next CSP provider, for example, CSP2, but the CSP provider may be executed. If one is sufficient, steps S13 to S19 may be executed for the next broadcast program (for example, broadcast program B) without confirmation to the remaining CSP providers. If a CSP provider capable of providing the content including the content of the broadcast program A is not found, steps S13 to S23 are executed for the next broadcast program (for example, broadcast program B).

On the other hand, in step S14, when the CSP 1 does not provide the search function (corresponding to the case where the CSP 1 provides the content server device 23), the control unit 18 tells the CSP 1 to the DB program information acquisition unit 102. An order is given to confirm whether or not there is content including the broadcast program A. The DB program information acquisition unit 102 outputs a search request for the content of the CSP 1 including the broadcast program A to the database device 30 (NO in step S14, step S16).

More specifically, the search request is included in the search request signal by the network data processing unit 16, and is output from the communication unit 191 to the database device 30 via the network 50. When the database device 30 receives the search request, it searches the database related to CSP1 of the data storage unit 305 for content including the contents of the broadcast program A, and transmits the search result to the receiving device 10. In the receiving device 10, the DB program information acquisition unit 102 receives the search result and confirms the search result. As a result of checking the search result, if the CSP1 can provide the content including the content of the broadcast program A, the DB program information acquisition unit 102 associates the CSP1 with the broadcast program A and CSP program information of the broadcast program A. Is updated (step S18).

If a CSP provider capable of providing content including the contents of the broadcast program A is found, steps S14 to S18 may be executed for the next CSP provider, for example, CSP2, but the CSP provider may be executed. If one is sufficient, steps S13 to S23 may be executed for the next broadcast program (for example, broadcast program B) without investigating the remaining CSP providers. The DB program information acquisition unit 102 investigates all the target CSPs, and if a CSP provider capable of providing the content including the contents of the broadcast program A is not found, the control unit 18 is the network data processing unit 16. To confirm the search result of the search server device 25 (NO in step S20, step S21). When a CSP provider capable of providing the content including the content of the broadcast program A is found in the search result of the search server device 25 by the network data processing unit 16, the network data processing unit 16 informs the broadcast program A of the CSP. Is linked to update the CSP program information of the broadcast program A (YES in step S22, step S23). If the CSP provider capable of providing the content including the content of the broadcast program A is not found in the search result of the search server device 25, the control unit 18 determines the next broadcast program (for example, the broadcast program B) in step S13. S23 is executed from (NO in step S22).
When the control unit 18 finishes confirming the CSP program information for all the target broadcast programs, the control unit 18 receives the broadcast program information from the CSP program information acquisition unit 102 and the DB program information acquisition unit 102, and the CSP linked to the broadcast program. The program information is stored in the EPG information management unit 106 (step S25). In the EPG information management unit 106, if there is program information acquired for the same broadcast program in the past, it may be updated, and if not, the received program information may be stored as a database.

By the above procedure, it is possible to acquire the EPG information associated with the broadcast program information and the CSP provider that provides the broadcast program.

(First Embodiment)
In the present embodiment, an operation example for the receiving device 10 to determine a recorded program by recording all programs is shown. More specifically, the receiving device 10 excludes the programs provided by the CSP provider from the recording targets among the programs scheduled to be recorded by recording all the programs.

FIG. 9 is a flowchart showing an example of processing operation when the receiving device according to the first embodiment displays program information.

When the user presses the program information display button on the remote controller 100 in order to display the program information of January 20, 2020, which is the future, on January 13, 2020, the remote controller 100 sets the specified date. The included program information display command signal is output. When the receiving device 10 receives the program information display command signal from the remote controller I / F unit 192, the control unit 18 takes out the program information display command from the program information display command signal and outputs it to the EPG generation processing unit 105 (step). S31). The EPG generation processing unit 105 acquires broadcast program information on a designated date from the broadcast program information acquisition unit 101 (step S32). The EPG generation processing unit 105 creates display program information data for each broadcast program included in the broadcast program information (steps S32, S33, S34).

More specifically, the EPG generation processing unit 105 has a CSP related to the program A from the CSP program information acquisition unit 102, the DB program information acquisition unit 103, or the network data processing unit 16 for a certain broadcast program (referred to as program A). Acquire and confirm program information. The network data processing unit 16 stores CSP program information acquired from the search server 25. If there is CSP program information related to program A, the EPG generation processing unit 105 links the CSP having CSP program information related to program A to the broadcast program information of program A, and displays the program information including them. Generate data (step S34). The EPG generation processing unit 105 executes step S34 for all the broadcast programs included in the broadcast program information to generate display program information data, and then outputs the display program information data to the output control unit 14. The output control unit 14 outputs the display program information data to the display unit 151, and the display program information is displayed from the display unit 151 (step S36).

By the above procedure, the user can view the program information of January 20, 2020 from the display unit 151.

FIG. 10 is a diagram showing an example of program information displayed by the receiving device according to the same embodiment, and is a display example of program information on January 20, 2020. According to the procedure of the flowchart of FIG. 9, the program information 620 is displayed on the display unit 151. The display frame 621 indicates that the user has displayed the program information (program guide) of January 20, 2020 on January 13, 2020. The display frame 622 indicates a broadcasting station name (broadcasting station A, broadcasting station B, etc.) and a channel number (ch1, ch2, etc.) that provide the broadcasting program included in the broadcasting program information. This display may be able to display information on a larger number of broadcasting stations by scrolling horizontally. The display frame 623 indicates the broadcast time of the broadcast program being displayed. The display frame 624 indicates a function that can be operated with respect to the program information 620.

The display frame 625 indicates a program scheduled to be broadcast by the broadcasting station E, which is the channel number ch5, at the broadcasting time shown in the display frame 623. Broadcast programs of broadcasting station E are shown for each time frame. In each time frame, program E1, program E2, program E3, program E4, program E5, program E6, and program E7 are shown as program names. Further, each time frame is marked with marks such as CSP5, CSP12, and CSP (referred to as CSP mark), indicating that the programs in the time frame with the mark are provided by the CSP indicated by the mark. .. The number after the CSP indicates a different CSP provider, including the number to indicate the name of the CSP provider. For example, CSP5 refers to a CSP provider named CSP5. The program information 620 displays the marks of 12 CSP providers from CSP1 to CSP12. The program frame of the program E3 is grayed out in a dark color, which indicates that there is no CSP provider that provides the program E3 and the recording / playback unit 17 does not record the program. Further, the program E1 is not given the CSP mark and is not grayed out, but this may indicate that the program is not targeted for recording due to a setting such as recording refusal. The contents of the display frame 625 are the same for other broadcasting stations.

Considering that the broadcast programs to which the CSP mark is given in the program information 620 are redistributed from the CSP, the receiving device 10 provides these broadcast programs as contents without recording them in the recording / playback unit 17. Broadcast programs can be received from the content server device 21 or the content server device 23. Therefore, if it is decided to record only the programs that are grayed out, such as programs A4 and A5, the use of the hard disk can be saved. Further, when the video is recorded on the HDD, a mark (referred to as an HDD mark) indicating the HDD may be added in the program frame.

FIG. 11 is a flowchart showing a processing operation example for the receiving device according to the embodiment to record a broadcast program.

The user presses the all-recording button for recording all the programs from the remote controller 100 in order to record all the programs of January 20, 2020 displayed in the program information 620 of FIG. When the remote controller 100 outputs the complete recording command signal for instructing the recording of all programs together with the information of the program to be recorded, the receiving device 10 receives the complete recording command signal. The complete recording command signal is input to the control unit 18 via the remote controller I / F unit 192, and the control unit 18 takes out the complete recording command and outputs the complete recording command to the recording data management unit 104. The recording data management unit 104 takes out the information of the program to be recorded from the received all recording instructions and updates the recording reservation data. While confirming the recording reservation data, the control unit 18 receives broadcast program information (broadcast program information of the program to be recorded) from the EPG information management unit 106 or the like immediately before the time when the program ordered to be fully recorded on January 20, 2020 starts. Acquires (including broadcast channels, broadcast times, etc.) (step S101). The control unit 18 confirms the CSP program information of the recording target program from the CSP program information acquisition unit 102, the DB program information acquisition unit 103, the network data processing unit 16, and the like (step S102). As a result of the confirmation, if the CSP of the program to be recorded does not provide the re-distributed program, the control unit 18 performs the recording process (NO in step S103, S104). The program C2 shown in FIG. 10 will be specifically described by way of example. Immediately before the start of the program C2, that is, shortly before 7:00 PM on 2020/1/20, when the control unit 18 starts the recording process in step S104, the control unit 18 issues a recording command for the program to be recorded to the recording / playback unit 17. Output. Further, the control unit 18 sets the channel of the program to be recorded (ch3 in the case of the program C2) and the output destination of the data received on that channel (recording / playback unit 17 in the present embodiment) to the output selection unit 12. specify. The output selection unit 12 has various functions to receive data from the tuner receiving the channel broadcasting the program to be recorded from the broadcast signal acquisition unit 11 and output the data to the recording / playback unit 17 which is the data output destination. Control the part. The control by the output selection unit 12 may be performed exactly at the broadcast start time of the program to be recorded. As described above, the recording / playback unit 17 records the channel of the program to be recorded. When the recording by the recording / playback unit 17 is completed, the recording data management unit 104 updates the recording management data, such as deleting the recording target program from the recording reservation data and adding the recording target program to the recorded data.

On the other hand, when the broadcast program information of the program to be recorded includes the provision of the re-distributed program by the CSP, the control unit 18 performs the recording skip process (YES in step S103, S105). The program C3 shown in FIG. 10 will be specifically described by way of example. Immediately before the start of the program C3, that is, shortly before 8:00 PM on 2020/1/20, when the control unit 18 starts the recording skip process, the recording / playback unit 17 stops the recording of the program to be recorded. Alternatively, the control unit 18 may stop the broadcast signal acquisition unit 11 from receiving the tuner that is receiving the channel of the program to be recorded. The recording data management unit 104 deletes the recording target program from the recording reservation data. By the above procedure, the recording / playback unit 17 skips the recording of the program to be recorded.

FIG. 12 is a diagram showing an example of program information displayed on the display unit after the receiving device according to the same embodiment has performed recording, and is a result of displaying the program information on the display unit 151 on 2/3/2020. Is. Regarding the programs A4, A5, C3, D6, E3, and F3, the program frame was grayed out as shown in FIG. 10, that is, the program was not provided by the CSP, but according to the procedure of FIG. It is recorded and stored in the HDD, and as shown in FIG. 12, an HDD mark is added to each program frame and displayed. According to the present embodiment, as compared with the case where all the received broadcast programs are recorded, the program frame with the CSP mark can be viewed without being recorded on the HDD. Therefore, the efficiency of using the HDD, which is a storage medium, is improved. Further, according to the present embodiment, in order to reduce the chance of recording, the power consumption of the receiving device 10 can be reduced. Note that program E1, program D4, and program F5 show examples of exceptional operations. The program E1 and the program D4 are broadcast programs that are not provided by the CSP but are not recorded, and are examples in which neither the CSP mark nor the HDD mark is given. The program F5 is a broadcast program provided by the CSP, but is an example of a case where the program is also recorded.

By the above procedure, the receiving device 10 can record all programs using the CSP program information, and among the broadcast programs scheduled to be recorded for all program recordings, the CSP provider provides broadcasts such as re-delivery. For programs, you can choose not to record. This makes it possible to save and use an HDD or the like for storing recorded programs.

(Second embodiment)
In the present embodiment, an example is shown in which the recorded program is deleted when it is found that the program recorded in the past by the receiving device 10 is provided by the content server device or the like.

FIG. 13 is a flowchart showing an example of processing operation for the receiving device according to the second embodiment to update the recorded program data of the HDD.

It is assumed that the user has recorded all the programs broadcast on January 20, 2020. In this case, in the displayed program information related to the broadcast program on January 20, 2020 in FIG. 10, the HDD mark is given instead of the CSP mark for all the programs. The user presses the HDD update command button of the remote controller 100 on February 3, 2020 in order to update the HDD while viewing the program information related to this broadcast program on the display unit 151. The remote controller 100 outputs an HDD update command signal including a designated date (January 20, 2020). The control unit 18 acquires an HDD update command from the HDD update command signal (step S201). The control unit 18 acquires broadcast program information from the EPG information management unit 106 (step S202). The control unit 18 confirms the recorded data stored in the recorded data management unit 104 for each program of the acquired broadcast program information. Regarding a certain program (referred to as program X) included in the acquired broadcast program information, the control unit 18 refers to the recorded data to confirm whether or not the program X is recorded in the HDD, and if it is recorded, the control unit 18 confirms whether or not the program X is recorded in the HDD. Confirm the CSP program information (YES in steps S204 and S205). In this embodiment, since it is assumed that all the programs included in the broadcast program information on January 20, 2020 are recorded in the HDD, steps S204 and S205 may be skipped.

The control unit 18 confirms the CSP program information stored in the CSP program information acquisition unit 102 for each program X. A case where a CSP that provides the program X is found in the CSP program information will be described, for example, by taking the program A3 of FIG. 10 as an example of the program X. Since the program A3 is provided by the CSP 1, the control unit 18 selects to delete the recorded data of the program A3 from the HDD and causes the recording / playback unit 17 to delete the program (YES, S208 in step S207). On the other hand, when the CSP that provides the program X is not found in the CSP program information, for example, the program A4 in FIG. 10 will be described as an example of the program X. Since there is no CSP provider that provides the program A4, the control unit 18 selects to leave the recorded data of the program A4 in the HDD (NO in step S207). When all the programs of the broadcast program information obtained from the processes from step S204 to step S208 are executed, all the programs are either provided by the CSP or stored in the HDD. Based on this state, the recorded data management unit 104 updates the recorded data. Further, when this state is displayed as program information, the display is the same as in FIG. However, in FIG. 12, program E1, program D4, and program F5 are examples of exceptional operations.

By the above procedure, it is determined whether to delete or keep the recorded data stored in the HDD based on the CSP program information, and when it is found that the recorded data is provided by the content server device or the like, the recorded program is deleted. be able to. As a result, the capacity of the HDD can be reduced without losing the opportunity to watch the program. In this embodiment, the HDD update command signal from the remote controller 100 is used as a trigger to update the HDD (step S201), but for example, the used capacity of the HDD is monitored by the control unit 18 or the like, and the used capacity of the HDD is used. The control unit 18 may generate a trigger for updating the HDD.
(Modification example)
In this modification, another operation example possible in the receiving device 10 shown in the present embodiment will be described.

FIG. 14 is a flowchart showing a processing operation example for reproducing the contents of the CSP selected from the displayed program information in the modified example. This example shows an example in which a program provided by CSP is reproduced from an EPG program guide of a broadcast program displayed as shown in the program display of FIG.

When the user presses the program information display button for displaying the EPG program guide from the remote controller 100, the program information display command signal is output from the remote controller 100 together with the program information identification information for specifying the broadcast program information such as the date. The control unit 18 of the receiving device 10 acquires a program information display command (step S301). When the control unit 18 orders the EPG generation processing unit 105 to display the program information, the EPG generation processing unit 105 generates the display program information data based on the program information specific information and outputs it to the output control unit 14. The output control unit 14 switches the current display and causes the display unit 151 to display the displayed program information (step S302).

FIG. 15 is a screen display example in which the CSP content is selected from the program information of the broadcast program and the selected content is played back in the modified example. FIG. 15A is an example of the display program information 620 displayed on the display unit 151, and when the user selects the CSP mark “CSP8” of the program frame 641 or the program frame 641 of the program B5 from the remote controller 100, the remote controller is used. 100 outputs a program selection command signal. The control unit 18 receives the program selection command signal and acquires the program selection command (step S303). The control unit 18 outputs a program selection command to the EPG generation processing unit 105.
