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

FIG. 6 is a functional block diagram showing a configuration example of the database device according to the embodiment. FIG. 6A is a functional block diagram of the database device, and FIG. It is a diagram schematically showing 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 to retrieve content from the outside, it transmits content program information to the database device 30 upon request, spontaneously, or periodically. The database device 30 stores the received content program information in the data storage section 305 .

The communication unit 301 has communication protocols such as TCP/IP and UDP/IP, and communicates with devices on the network 50 .

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

The request processing unit 303 receives commands from the control unit 302 and executes the commands. 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. .

Upon receiving a search request from the request processing unit 303 together with 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 a CSP that provides content related to the program identification information. The search unit 304 provides the requested content, but if a CSP is found, the search unit 304 generates CSP program information including the name of the CSP provider and the URL, which is access information to the content. The search section 304 outputs the CSP program information to the request processing section 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 or the like on the network 50, a catalog related to the program information, and the like. Note that the data storage unit may be located outside the content server device 21 .

Upon receiving the program information provision request, the data provision 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 the CSP program information to the requester of the program information.

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

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

An operation example when the receiving apparatus according to the embodiment generates and updates EPG information data for displaying program information on the display unit 151 will be described below.

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 . CSP program information and 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. Recorded data is managed by the recorded data management unit 104 .

FIG. 7 is a flowchart showing an example of processing operation when the receiving device according to the embodiment updates CSP program information. It is an example of a flow chart in the case of setting such as performing as a target. For example, an update button may be provided on the remote controller 100, and the CSP program information may be updated when the user presses the button.

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 voluntarily acquire and update broadcast program information from the broadcast signal while the broadcast signal acquisition unit 11 is receiving the broadcast signal. The control unit 18 determines whether there is a CSP provider (providing the content server device 21 or the content server device 23) presently 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, a broadcast program A1 will be described as one of the broadcast programs included in the broadcast program information. The user can select a CSP provider whose program information is to be confirmed. Steps S12 and S24 indicate that steps S13 to S23 are executed for all target broadcast programs.

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

A display frame 601 is a setting portion for CSP1, and similarly, settings for each CSP provider (CSP2 to CSP5) can be made for each row. A 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 in each row. Check the checkbox of the line to be FIG. 8 shows an example of acquiring content program information from a CSP provider other than CSP3. A display frame 603 indicates the name of the CSP provider on each line. A display frame 604 indicates buttons for changing the display order of CSP providers on the selection screen. A display frame 605 indicates 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 user access accounts other than CSP3 are set. A display frame 606 indicates a scroll bar for scrolling the display of the selection screen (from the display frame 602 to the display frame 605). In FIG. 8, only CSP1 to CSP5 are displayed, but other CSP providers are also set and can be displayed by scrolling.

Returning to step 13 in FIG. 7, the control unit 18 confirms whether or not the CSP providers checked in the display frame 602 of the selection screen in FIG. As one of the CSP providers to be confirmed, CSP1 will be described as an example. Steps S13 and S19 indicate performing steps S14 to S18 for all CSP providers of interest.

The control unit 18 confirms whether the CSP 1 provides a search function (step S14). Normally, a CSP provider that provides a search function provides dedicated software called WebAPI, and if the receiving device 10 has the WebAPI of the CSP provider installed, the CSP provider can perform a search. It can be determined whether the function is provided or not. When CSP1 provides a search function (equivalent to when CSP1 provides content server device 21), control unit 18 outputs a search request command to CSP1 to CSP program information acquisition unit 102. do. Upon receiving the search request command to CSP1, 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 a search request signal by the network data processing unit 16 and output from the communication unit 191 via the network 50 to the content server device 21 of the CSP1. Upon receiving the search request, the content server device 21 of the CSP 1 searches the data storage unit 211 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 CSP program information acquisition unit 102 receives the search results and confirms the search results. As a result of checking the search result, if the CSP1 can provide 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 obtains the CSP program information of the broadcast program A. is updated (step S18).

If a CSP provider capable of providing content including the content of broadcast program A is found, steps S14 to S18 may be executed for the next CSP provider, for example, CSP2. is sufficient, steps S13 to S19 may be executed for the next broadcast program (for example, broadcast program B) without confirming the rest of the CSP providers. If no CSP provider capable of providing content including the contents of broadcast program A is found, steps S13 to S23 are executed for the next broadcast program (for example, broadcast program B).

On the other hand, in step S14, if CSP1 does not provide a search function (corresponding to the case that CSP1 provides content server device 23), control unit 18 instructs DB program information acquisition unit 102 to An instruction to confirm whether or not there is content including broadcast program A is issued. The DB program information acquisition unit 102 outputs a search request for the contents of the CSP1 including the broadcast program A to the database device 30 (NO in step S14, step S16).

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

If a CSP provider capable of providing content including the content of broadcast program A is found, steps S14 to S18 may be executed for the next CSP provider, for example, CSP2. 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 target CSPs, and if no CSP provider capable of providing content including the content of the broadcast program A is found, the control unit 18 causes the network data processing unit 16 confirms the search result of the search server device 25 (NO in step S20, step S21). When a CSP provider capable of providing content including the content of broadcast program A is found in the search result of search server device 25 by network data processing unit 16, network data processing unit 16 adds the CSP to broadcast program A. are linked, and the CSP program information of the broadcast program A is updated (YES in step S22, step S23). In the search result of the search server device 25, if no CSP provider capable of providing content including the contents of the broadcast program A is found, the control unit 18 determines the next broadcast program (for example, the broadcast program B) in step S13. , S23 is executed (NO in step S22).
After confirming the CSP program information for all target broadcast programs, the control unit 18 obtains 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 section 106 (step S25). In the EPG information management unit 106, if there is program information acquired in the past regarding the same broadcast program, it may be updated, and if not, the received program information may be stored as a database.

Through the above procedure, it is possible to acquire the EPG information in which the broadcast program information and the CSP provider that provides the broadcast program are linked.

(First embodiment)
In the present embodiment, an operation example for the receiving apparatus 10 to determine programs to be recorded by recording all programs will be described. More specifically, the receiving apparatus 10 excludes programs provided by the CSP provider from the programs to be recorded among programs scheduled to be recorded by all program recording.

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 on January 13, 2020 to display program information for the future January 20, 2020, the remote controller 100 displays the specified date. It outputs the program information display command signal that contains the program information. When the receiving device 10 receives the program information display command signal at the remote control I/F unit 192, the control unit 18 extracts 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 the broadcast program information for the specified 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 obtains the 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 (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 associates the CSP with the CSP program information related to program A with the broadcast program information of program A, and generates display program information including them. Data is generated (step S34). After executing step S34 for all broadcast programs included in the broadcast program information and generating display program information data, the EPG generation processing unit 105 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).

Through the above procedure, the user can view the program information for 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 embodiment, and is a display example of program information on January 20, 2020. FIG. Program information 620 is displayed on the display unit 151 according to the procedure of the flowchart of FIG. A display frame 621 indicates that the user displayed the program information (program guide) for January 20, 2020 on January 13, 2020. FIG. A display frame 622 indicates the broadcasting station name (broadcasting station A, broadcasting station B, etc.) and channel number (ch1, ch2, etc.) that provide the broadcasting program included in the broadcasting program information. This display may display information on a larger number of broadcasting stations by scrolling horizontally. A display frame 623 indicates the broadcast time of the displayed broadcast program. A display frame 624 indicates functions that can be operated with respect to the program information 620 .

A display frame 625 indicates a program scheduled to be broadcast by the broadcasting station E whose channel number is ch5 at the broadcast time indicated in the display frame 623 . Broadcast programs of broadcasting station E are shown for each time frame. Program E1, Program E2, Program E3, Program E4, Program E5, Program E6, and Program E7 are shown as program names in each time frame. Marks such as CSP5, CSP12, and CSP (referred to as CSP marks) are shown in each time frame, indicating that programs in time frames with marks are provided by the CSPs indicated by the marks. . The numbers after CSP indicate different CSP providers, including the number to indicate the name of the CSP provider. For example, CSP5 indicates a CSP provider named CSP5. The program information 620 displays 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 that the program E3 is not recorded in the recording/reproducing section 17 . The program E1 is neither given a CSP mark nor grayed out. 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 attached in the program information 620 are redistributed from the CSP, the receiving device 10 provides these broadcast programs as content 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 that is Therefore, recording only grayed-out program frames such as programs A4 and A5 leads to saving of hard disk usage. Also, when the program is recorded on the HDD, a mark indicating the HDD (referred to as an HDD mark) may be added within the program frame.

FIG. 11 is a flowchart showing an example of processing operation for recording a broadcast program by the receiving device according to the embodiment.

The user presses an all-recording button for recording all programs from the remote controller 100 in order to record all the programs for January 20, 2020 displayed in the program information 620 of FIG. When the information of the program to be recorded and the all-recording command signal for commanding all-program recording are output from the remote controller 100, the receiving apparatus 10 receives the all-recording command signal. The all-recording command signal is input to the control unit 18 via the remote controller I/F unit 192 , and the control unit 18 extracts the all-recording command and outputs the all-recording command to the recorded data management unit 104 . The recording data management unit 104 extracts the information of the program to be recorded from the received all-recording command, and updates the recording reservation data. While checking the recording reservation data, the control unit 18 receives the broadcast program information ( (including broadcast channel, broadcast time, etc.) is obtained (step S101). The control unit 18 confirms the CSP program information of the program to be recorded from the CSP program information acquisition unit 102, the DB program information acquisition unit 103, the network data processing unit 16, or the like (step S102). As a result of the confirmation, if there is no redistribution program provided by the CSP of the program to be recorded, the control unit 18 performs recording processing (NO in step S103, S104). The program C2 shown in FIG. 10 will be specifically described as an example. Immediately before program C2 starts, that is, shortly before 7:00 PM on January 20, 2020, when the control unit 18 starts recording processing in step S104, the recording/playback unit 17 is instructed to record the program to be recorded. Output. The control unit 18 also instructs the output selection unit 12 to specify the channel of the program to be recorded (ch3 in the case of program C2) and the output destination of the data received on that channel (the recording/playback unit 17 in this embodiment). specify. The output selection unit 12 receives data from the broadcast signal acquisition unit 11 from the tuner that is receiving the channel broadcasting the program to be recorded, and outputs the data to the recording/playback unit 17, which is the data output destination. control the department. The control by the output selection unit 12 may be performed at exactly 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 deletes the recording target program from the recording reservation data, adds the recording target program to the recorded data, and updates the recording management data.

On the other hand, if the broadcast program information of the program to be recorded includes the redistribution program provided by the CSP, the control unit 18 performs recording skip processing (YES in step S103, S105). The program C3 shown in FIG. 10 will be specifically described as an example. Immediately before program C3 starts, that is, shortly before 8:00 PM on January 20, 2020, the control unit 18 starts recording skip processing, and causes the recording/playback unit 17 to stop recording the recording target program. Alternatively, the control unit 18 may cause the broadcast signal acquisition unit 11 to stop 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. According to the above procedure, the recording/playback unit 17 skips recording of the program to be recorded.

FIG. 12 is a diagram showing an example of program information displayed on the display unit after recording is performed by the receiving device according to the embodiment. is. As for 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. The program is recorded and stored in the HDD, and is displayed with an HDD mark attached to each program frame as shown in FIG. According to this embodiment, compared to the case where all received broadcast programs are recorded, it is possible to view the program frames to which the CSP mark is assigned without recording them on the HDD. Therefore, the efficiency of using the HDD, which is a storage medium, is improved. Moreover, according to the present embodiment, the power consumption of the receiving apparatus 10 can be reduced because the chances of recording are reduced. Note that program E1, program D4, and program F5 show examples of exceptional operations. Programs E1 and D4 are broadcast programs that are not provided by a CSP, but are broadcast programs that are not subject to recording, and are examples in which neither the CSP mark nor the HDD mark is given. A program F5 is a broadcast program provided by a CSP, but is also recorded.

According to 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 in the all program recording, the broadcasts that are provided by the CSP provider for redistribution, etc. Programs can be selected not to be recorded. As a result, it is possible to conserve the HDD and the like for storing recorded programs.

(Second embodiment)
In this embodiment, an example of deleting the recorded program when it is found that the program recorded by the receiving device 10 in the past is provided by a content server device or the like will be described.

FIG. 13 is a flow chart showing a processing operation example for the receiving device according to the second embodiment to update the recorded program data in the HDD.

It is assumed that the user recorded all broadcast programs on January 20, 2020. In this case, in the display program information related to the program broadcast on January 20, 2020 in FIG. 10, the HDD mark is given to all the programs instead of the CSP mark. The user presses the HDD update command button on the remote controller 100 on February 3, 2020 to update the HDD while viewing the program information related to this broadcast program on the display unit 151 . Remote controller 100 outputs an HDD update command signal including the specified date (January 20, 2020). The control unit 18 acquires the 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 checks the recorded data stored in the recorded data management unit 104 for each program of the acquired broadcast program information. For a certain program (assumed to be program X) included in the acquired broadcast program information, the control unit 18 refers to recorded data to check whether or not program X has been recorded on the HDD. CSP program information is confirmed (YES in steps S204 and S205). In this embodiment, all programs included in the broadcast program information for January 20, 2020 are recorded on the HDD, so steps S204 and S205 may be skipped.

The control unit 18 checks the CSP program information stored in the CSP program information acquisition unit 102 for each program X. FIG. A case where a CSP providing program X is found in the CSP program information will be described with program A3 in FIG. 10 as an example of program X. FIG. Since the program A3 is provided by the CSP 1, the control unit 18 selects deletion of the recorded data of the program A3 from the HDD, and causes the recording/playback unit 17 to delete the data (YES in step S207, S208). On the other hand, a case where no CSP providing program X is found in the CSP program information will be described with program A4 in FIG. Since there is no CSP provider that provides program A4, the control unit 18 selects to leave the recorded data of program A4 in the HDD (NO in step S207). After the processing from step S204 to step S208 is performed for all programs in the acquired broadcast program information, all 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. Also, if this state is displayed as program information, the same display as in FIG. 12 is obtained. However, in FIG. 12, program E1, program D4, and program F5 are examples of exceptional operations.

According to the above procedure, it is determined whether the recorded data stored in the HDD should be deleted or left according to the CSP program information, and if it is found that the recorded data is provided by a content server device or the like, the recorded program is deleted. be able to. As a result, it is possible to reduce the capacity of the HDD 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 for updating the HDD (step S201). The control unit 18 may generate a trigger for updating the HDD.
(Modification)
In this modified example, another operation example that can be performed by the receiving device 10 shown in this embodiment will be described.

FIG. 14 is a flow chart showing an example of a processing operation for reproducing content of a CSP selected from display program information in a modified example. This example shows an example of reproducing a program provided by a CSP from an EPG program table of broadcast programs displayed as shown in FIG.

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

FIG. 15 shows an example of a screen display from selecting CSP content from program information of a broadcast program to reproducing the selected content in the modified example. FIG. 15A shows an example of the displayed program information 620 displayed on the display unit 151. When the user selects the program frame 641 or the CSP mark "CSP8" of the program frame 641 of the program B5 from the remote control 100, the remote control 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 . The EPG generation processing unit 105 identifies the broadcast program "program B5" from the program selection command, acquires parameters such as the URL of the CSP providing the broadcast program from the CSP program information linked to the broadcast program, and extracts the content. A content request is made to the CSP of the server device 21 or 23 . When the content request is output to the content server device 21 or 23 via the network data processing unit 16, the network data processing unit 16 starts receiving the content transmitted from the content server device 21 or 23 (step S304). When the network data processing unit 16 receives the content using the browser function and outputs the content to the output control unit 14, the content is output from the display unit 151 so that it can be viewed (step S305).

According to the above procedure, the user can reproduce the broadcast program from the content server device simply by selecting the program frame in the EPG program table of the displayed broadcast program. Also, since the broadcast program and the CSP are linked, the display of (e) can be obtained directly from the display of (a) in FIG. 15 . That is, according to this procedure, a so-called deeplink that directly opens the relevant program page becomes possible. In a normal reproduction process, steps (a) to (e) must be performed. That is, when the user selects a program on the screen (a), the start screen (b) is displayed, and the program is selected again from the list provided by the CSP on the TOP screen (c). Then, after the detailed screen of the selected program is displayed as shown in (d), the playback screen of (e) is displayed. In this embodiment, since the broadcast program information and the CSP are linked, direct access like Deeplink is possible.

FIG. 16 is a diagram showing a first example of program information displayed in the modified example. In the first example according to this modification, for example, when the user selects by clicking the program frame 641 of the program information 620 in FIG. , the video of the program B3, which is the program of the program frame 641, is displayed. When the user selects the program frame 641, the video of the program B3 is displayed on the display unit 151 after the receiving device 10 performs real-time processing of the video data transmitted from the content server device of the CSP 8 that provides the program B3. You can also

FIG. 17 is a diagram showing a second example of program information displayed in the modified example. In the second example according to this modification, for example, when the user selects by clicking the program frame 641 of the program information 620 in FIG. Information on programs related to program B3, which is a program, is displayed. For example, when the program B3 is a series program having a plurality of broadcast episodes, and the CSP provider (CSP8 in this embodiment) provides them, the receiving device 10 receives related broadcasts ( Broadcast talk) can be displayed.

FIG. 18 is a diagram showing a third example of program information displayed in the modified example. In the third example according to this modified example, for example, when the user selects by clicking the program frame 641 of the program information 620 in FIG. The main video of the image frame 662 can be played.

According to at least one embodiment described above, it is possible to provide a receiving apparatus and control method for efficiently storing a broadcast program in a storage medium.
