In addition, the data 2352 includes information related to the content, such as the URL of the content provided by the CSP.

5 is a functional block diagram of a configuration example of the search server device according to the embodiment, wherein (a) shows a functional block diagram, and (b) shows an example of data stored in the data storage unit 254 .

The retrieval server device 25 provides CSP program information according to the request of the receiving apparatus 10 . The retrieval server device 25 can retrieve the content related to the retrieval keyword from the contents accessible on the network 50 based on the received retrieval keyword, and can send the retrieval result (including CSP program information) to the transmission source of the retrieval keyword supply. For example, the content server device 21 is included in the retrieval object of the retrieval server device 25 . In addition, the search server device 25 may store the data searched in the past in the data storage unit 254 and use it for the search.

The search unit 250 searches the database of the data storage unit 254 and the content that can be searched on the network 50 when receiving the search request and program identification information such as the program name of the content from the request processing unit 253 . The retrieval unit 250 generates the CSP program information so as to include URLs and the like, which are information for specifying the content server device 21 or the like that can provide the program related to the program identification information. The retrieval unit 250 outputs the CSP program information to the request processing unit 253 .

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

The control unit 252 may include a function of a CPU, recognize commands from a command signal received from a device on the network 50 or the like via the communication unit 251 , and control various functional units of the search server device 25 based on the commands. In addition, the control unit 252 outputs data output from the various functional units to the communication unit 251 . For example, when the control unit 252 receives a program information retrieval request signal including a retrieval keyword from the receiving apparatus 10 and acquires a program information retrieval request command, it controls the function of the retrieval server device 25 to execute program information retrieval.

The request processing unit 253 receives the command from the control unit 252 and executes the command. When receiving the program information retrieval 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 retrieval request command to the retrieval unit 250 to make a retrieval request.

The data storage unit 254 may be, for example, a hard disk, and stores search results such as CSP program information searched by the search unit 250 . It should be noted that the data storage unit may be located outside the content server device 21 .

FIG. 5( b ) is an example of the CSP program information stored in the data storage unit 254 , and the CSP program information is a search result obtained by the search by the search unit 250 . The data 2541 shows the CSP of the content server apparatus 23 that provides the broadcast program by the broadcast program broadcasted by the broadcast signal. For example, the data 252 shows that the CSPs providing the program 32 as the broadcast program are CSP1 and CSP8 and shows the URLs as the access destinations of the CSP1 and CSP8. It should be noted that the program 11 and the program 32 only need to be able to identify the program, and may be the program name or the program identification information or the like.

When receiving a search keyword such as 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 it to the control unit 252 . The control unit 213 outputs the CSP program information to the request source.

6 is a functional block diagram of a configuration example of the database apparatus according to the embodiment, (a) is a functional block diagram of the database apparatus, and (b) is a schematic diagram showing a database of the data storage unit 305 as a storage medium of the database apparatus 's diagram.

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

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

The control unit 302 may include a function of a CPU, recognize commands from a command signal received from a device or the like on the network 50 via the communication unit 301 , and control various functional units of the database device 30 based on the commands. In addition, the control unit 302 outputs the data output from the various functional units to the communication unit 301 .

The request processing unit 303 receives the command from the control unit 302 and executes the command. When receiving 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 to make a search request.

The search unit 304 may search the database of the data storage unit 305 for a CSP that provides the content related to the program identification information in the database of the data storage unit 305 when receiving the search request and program identification information such as the program name of the content from the request processing unit 303 . When the retrieval unit 304 finds a CSP that provides the content requested for retrieval, it generates CSP program information including the name of the CSP provider, the URL as access information to the content, and the like. The retrieval unit 304 outputs the CSP program information to the request processing unit 303 .

The data storage unit 305 may be, for example, a hard disk, and stores content program information in terms of CSPs received from the content server device 23 or the like on the network 50 , contents related to the program information, and the like. It should be noted that the data storage unit may be located outside the content server device 21 .

When receiving a request for providing program information, 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 it to the control unit 302 . The control unit 302 outputs the CSP program information to the program information request source.

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

(b) of FIG. 6 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 the content program information of the content provided by the CSP3, the program name of the content, and the information related to the content, such as URL. In addition, when the content provided by the CSP3 includes the content of the broadcast program provided by the digital broadcast, the channel, broadcast time, etc. of the digital broadcast may be included in the CSP program information.

Hereinafter, an example of the operation when the reception apparatus according to the embodiment generates and updates EPG information data for displaying program information on the display unit 151 will be described.

The EPG information is data for generating and displaying program information, and includes broadcast program information, CSP program information, content program information, recording completion data, and the like. The 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 recording completion data is managed by the recording data management unit 104 .

7 is a flowchart showing an example of the processing operation when the receiving apparatus according to the embodiment updates the CSP program information, in which the receiving apparatus automatically or periodically acquires the CSP program information through a program of the receiving apparatus or the like. flow under certain conditions

Example of a diagram. It should be noted that, for example, an update button may be provided on the remote controller 100, and the CSP program information may be updated by the user pressing the update 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 autonomously 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 confirms whether there is a CSP provider (the content server device 21 or the content server device 23 ) that provides the broadcast program on the network currently or in the future for the broadcast program included in the acquired broadcast program information (steps S12 to S24 ) ). For example, as one of the broadcast programs included in the broadcast program information, the broadcast program A1 will be described as an example. The user can select a CSP provider to be checked for program information. Steps S12 and S24 show the case where steps S13 to S23 are executed for all targeted broadcast programs.

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

The display frame 601 is a setting part for CSP1, and similarly, setting for each CSP provider (CSP2 to CSP5) can be performed on a row-by-row basis. The display box 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 row. If the corresponding CSP provider is to be enabled, the user checks the corresponding row. frame. FIG. 8 shows an example in the case of acquiring content program information from a CSP provider other than CSP3. Display box 603 shows the name of the CSP provider for each row. A display frame 604 shows a button for changing the display order of CSP providers on the selection screen. A display box 605 shows the setting status of the access account for accessing the server provided by the CSP provider of each row. FIG. 8 shows an example in which an access account in which the user accesses CSPs other than CSP3 is set. A display frame 606 shows a scroll bar for scrolling the displays 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 can be displayed by scrolling.

Returning to step 13 in FIG. 7 , the control unit 18 checks whether the CSP provider checked in the display frame 602 of the selection screen in FIG. 8 provides content including the content of the broadcast program A. As one of the CSP providers to be confirmed, the description will be given by taking CSP1 as an example. Steps S13 and S19 show the case where steps S14 to S18 are executed for all the CSP providers to be targeted.

The control unit 18 confirms whether or not the CSP 1 provides the retrieval function (step S14). Usually, a CSP provider that provides a search function will provide special software such as Web API, and the receiving device 10 can determine whether the conforming CSP provider provides a search function as long as the Web API of the conforming CSP provider is installed. When the CSP 1 provides the retrieval function (equivalent to the case where the CSP 1 provides the content server device 21 ), the control unit 18 outputs a retrieval request command for the CSP 1 to the CSP program information acquisition unit 102 . When the CSP program information acquisition unit 102 receives the search request command for the CSP1, it outputs a search request to the CSP1 (YES in step S14, step S15).

More specifically, the retrieval request is processed by the network data processing unit 16 and is output from the communication unit 191 to the content server device 21 of the CSP 1 via the network 50 and included in the retrieval request signal. When the content server device 21 of the CSP 1 receives a search request, the data storage unit 211 searches whether there is content including the content of the broadcast program A, and transmits the search result to the receiving device 10 . In the receiving apparatus 10, the CSP program information acquisition unit 102 receives the search result and confirms the search result. When it is concluded that the CSP1 can provide the content including the content of the broadcast program A after checking the search result, the CSP program information acquisition unit 102 associates the CSP1 with the broadcast program A and updates the CSP program information of the broadcast program A (step S18).

When a CSP provider that can provide content including the content of the broadcast program A is found, steps S14 to S18 may be executed for, for example, CSP2, which is the next CSP provider, but one CSP provider is sufficient In the case of , steps S13 to S19 may be executed for the next broadcast program (eg, broadcast program B) without confirming the remaining CSP providers. If no CSP provider that can provide content including the content of the broadcast program A is found, steps S13 to S23 are performed for the next broadcast program (eg, the broadcast program B).

On the other hand, in step S14, when the CSP 1 does not provide the retrieval function (equivalent to the case where the CSP 1 provides the content server device 23), the control unit 18 executes a procedure for confirming whether the CSP 1 has the included broadcast to the DB program information acquisition unit 103 or not. A confirmation command for the content of program A. The DB program information acquisition unit 103 outputs a retrieval request including the content of the CSP1 of the broadcast program A to the database device 30 (NO in step S14, step S16).

More specifically, the search request is processed by the network data processing unit 16 and is output from the communication unit 191 to the database device 30 via the network 50 so as to be included in the search request signal. When receiving a 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 apparatus 10, the DB program information acquisition unit 103 receives the search result and confirms the search result. When it is concluded that the CSP1 can provide the content including the content of the broadcast program A after checking the search result, the DB program information acquisition unit 103 associates the CSP1 with the broadcast program A and updates the CSP program information of the broadcast program A (step S18).

When a CSP provider that can provide content including the content of the broadcast program A is found, steps S14 to S18 may be executed for, for example, CSP2, which is the next CSP provider, but one CSP provider is enough In such a case, steps S13 to S23 may be executed for the next broadcast program (eg, broadcast program B) without conducting the investigation of the remaining CSP providers. When the DB program information acquisition unit 103 searches all the target CSPs and fails to find a CSP provider that can provide content including the content of the broadcast program A, the control unit 18 causes the network data processing unit 16 to confirm the search The retrieval result of the server device 25 (NO in step S20, step S21). When the search result of the search server device 25 confirmed by the network data processing unit 16 is that a CSP provider capable of providing content including the content of the broadcast program A has been found, the network data processing unit 16 associates the CSP with the content of the broadcast program A. The broadcast program A is associated, and the CSP program information of the broadcast program A is updated (Yes in step S22, step S23). When the search result of the search server device 25 is that no CSP provider capable of providing content including the content of the broadcast program A is found, the control unit 18 executes steps S13 to S23 for the next broadcast program (for example, the broadcast program B). (NO in step S22).

After the control unit 18 completes the confirmation of the CSP program information for all targeted broadcast programs, the CSP program information acquisition unit 102 and the DB program information acquisition unit 103 associate the broadcast program information with the CSP programs associated with the broadcast programs. The 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 is updated, and if there is no program information, the received program information is stored as a database.

Through the above steps, EPG information that associates the broadcast program information with the CSP provider that provides the broadcast program can be acquired.

first embodiment

In the present embodiment, an example of the operation of the receiving apparatus 10 for determining a recorded program to be recorded based on the full program recording method is shown. More specifically, the receiving apparatus 10 excludes the programs that the CSP provider will provide from the recording objects among the programs scheduled to be recorded based on the full program recording method.

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

In order to display the future program information on January 20, 2020 on January 13, 2020, the user presses the display button of the program information with the remote controller 100, and at this time, the remote controller 100 outputs the program information display command signal including the specified day . When the receiving device 10 receives the program information display command signal via the remote controller 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 of the specified day 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, and S34).

More specifically, the EPG generation processing unit 105 acquires the CSP program 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). information and confirm. The CSP program information acquired from the search server 25 is stored in the network data processing unit 16 . If there is CSP program information related to the program A, the EPG generation processing unit 105 associates the CSP with the CSP program information related to the program A and the broadcast program information of the program A, and generates a display so as to include the association relationship. Program information data (step S34). The EPG generation processing unit 105 performs step S34 for all 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 part 14 outputs the display program information data to the display part 151, and displays the display program information from the display part 151 (step S36).

Through the above steps, the user can view the program information on January 20, 2020 from the display unit 151 .

FIG. 10 is a diagram showing an example of program information displayed by the receiving apparatus according to the embodiment, and is an example of display of program information on January 20, 2020. Through the steps of the flowchart of FIG. 9 , the program information 620 is displayed on the display unit 151 . The display frame 621 shows a case where the user displays the program information (program table) of January 20, 2020 on January 13, 2020. The display frame 622 shows the broadcasting station names (broadcasting station A, broadcasting station B, etc.) and channel numbers (ch1, ch2, etc.) of the broadcasting programs included in the broadcasting program information are provided. This display can display more information of radio stations by scrolling horizontally. A display frame 623 shows the broadcast time of the displayed broadcast program. Display box 624 shows functions that can operate on program information 620 .

The display frame 625 shows the program that the broadcasting station E at the channel number ch5 is scheduled to broadcast at the broadcast time shown in the display frame 623 . The broadcast programs of the broadcast station E are shown in time frames. In each time frame, program E1, program E2, program E3, program E4, program E5, program E6, and program E7 are shown as program names. In addition, markers such as CSP5, CSP12, and CSP (referred to as CSP markers) are shown in each time frame, and the program representation of the marked time frame is provided by the CSP indicated by the marker. The numbers after CSP indicate different CSP providers, and the name of the CSP provider is shown in the inclusion of numbers. For example, CSP5 represents a CSP provider with a name like CSP5. In the program information 620, the marks of 12 CSP providers from CSP1 to CSP12 are displayed. The program frame of the program E3 is grayed out with a dark color, which means that there is no CSP provider that provides the program E3 and that the recording is not being performed in the recording and playback unit 17 . In addition, the program E1 is not assigned a CSP mark and is not grayed out, but this may also mean that it is not set as a recording target according to settings such as recording rejection. It should be noted that the above-mentioned content of the display frame 625 is the same for other broadcasting stations.

Considering that the broadcast programs to which the CSP flag is added in the program information 620 will be redistributed from the CSP, the receiving apparatus 10 can provide the broadcast programs as content from the broadcast program without recording these broadcast programs in the recording and playback unit 17 . The content server apparatus 21 or the content server apparatus 23 receives the broadcast program. Therefore, if only the programs in the grayed-out program frames such as programs A4 and A5 are recorded, it is possible to save the use of the hard disk. In addition, when recording is performed on the HDD, a mark indicating the HDD (referred to as an HDD mark) may be added to the program frame.

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

In order to perform full program recording of the program on January 20, 2020 displayed in the program information 620 of FIG. 10 , the user presses the full record button for performing full program recording from the remote controller 100 . When an all-recording command signal instructing full-program recording and information of a program to be recorded are output from the remote controller 100, the receiving apparatus 10 receives the all-recording command signal. The all-record 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 all-record command and outputs the all-record 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 full recording command, and updates the recording reservation data. The control unit 18 confirms the recording reservation data, and acquires broadcast program information (including broadcast channels, broadcast time, etc.) (step S101). The control unit 18 confirms the CSP program information from the CSP program information acquisition unit 102 , the DB program information acquisition unit 103 , the network data processing unit 16 , or the like for the recording target program (step S102 ). When the result of the confirmation is that there is no provision of a redistribution program by the CSP for the program to be recorded, the control unit 18 performs a recording process (NO in step S103, S104). The program C2 shown in FIG. 10 will be described in more detail as an example. The control unit 18 starts the recording process in step S104 just before the start of the program C2, that is, a little earlier than PM7:00 on January 20, 2020, and outputs a recording command of the recording target program to the recording and playback unit 17 at this time. In addition, the control unit 18 designates, to the output selection unit 12, the channel of the recording target program (in the case of the program C2, ch3), and the output destination of the data received by the channel (the recording and playback unit 17 in this embodiment). . The output selection unit 12 controls various functional units so as to receive, from the broadcast signal acquisition unit 11, data from a tuner that receives a channel that broadcasts a program to be broadcast and recorded, and outputs the data to the recording and playback unit 17 as a data output destination . The control by the output selection unit 12 may be performed just at the broadcast start time of the recording target program. Through the above steps, the recording and playback unit 17 records the channel of the recording target program. When the recording by the recording and playback unit 17 is completed, the recording data management unit 104 updates the recording management data by deleting the recording target program from the recording reservation data, adding the recording target program to the recording completion data, or the like.

On the other hand, when there is provision of a redistribution program by CSP in the broadcast program information of the recording target program, the control unit 18 performs recording skip processing (YES in step S103, S105). The program C3 shown in FIG. 10 will be described in more detail as an example. The control unit 18 starts the recording skip process just before the start of the program C3, that is, before PM8:00 on January 20, 2020, and causes the recording and playback unit 17 to stop the recording of the recording target program at this time. Alternatively, the control unit 18 causes the broadcast signal acquisition unit 11 to stop reception of the tuner that receives the channel of the recording target program. The recording data management unit 104 deletes the recording target program from the recording reservation data. Through the above steps, the recording and playback unit 17 skips the recording of the recording target program.

FIG. 12 is a diagram showing an example of program information displayed on the display unit after the receiving apparatus according to the embodiment performs recording, and is the result of displaying the program information on the display unit 151 on February 3, 2020. Programs A4, A5, C3, D6, E3, and F3 are broadcast programs whose program boxes are grayed out as shown in FIG. 10, that is, programs are not provided by the CSP, and are recorded and stored in the HDD through the steps in FIG. 11. As shown in FIG. 12, the status is displayed with an HDD mark in each program frame. According to the present embodiment, compared to the case where all received broadcast programs are recorded, the program frame assigned the CSP mark can be viewed without recording on the HDD. Therefore, the use efficiency of the HDD as a storage medium is improved. In addition, according to the present embodiment, since the opportunity for recording is reduced, the power consumption and the like of the receiving apparatus 10 are also reduced. It should be noted that the program E1, the program D4, and the program F5 show examples of exceptional actions. The program E1 and the program D4 are broadcast programs that are not provided by the CSP and are not targeted for recording, and are examples in which neither the CSP mark nor the HDD mark is assigned. The program F5 is a broadcast program in which a program is provided by the CSP, but is also an example of a case where video recording is performed.

Through the above steps, the receiving device 10 can use the CSP program information to perform full-program recording, and can perform non-recording of broadcast programs that provide re-distribution, etc., in the broadcast programs scheduled for recording of full-program recording, according to the presence or absence of CSP providers. s Choice. As a result, the HDD and the like for storing the recorded program can be used sparingly.

Second Embodiment

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

13 is a flowchart showing an example of a processing operation for updating the recorded program data of the HDD by the receiving apparatus according to the second embodiment.

The user sets the broadcast program on January 20, 2020 as a program for which full program recording is performed. In this case, in the displayed program information related to the broadcast program on January 20, 2020 in FIG. 10 , there is a case where the HDD mark is assigned to all the programs instead of the CSP mark. 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 the broadcast program on the display unit 151 . The remote controller 100 outputs an HDD update command signal including the specified day (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 recording completion data stored in the recording data management unit 104 for each program of the acquired broadcast program information. For a certain program (referred to as program X) included in the acquired broadcast program information, the control unit 18 refers to the recording completion data to check whether or not the program X has been recorded on the HDD, and if so, checks the CSP program information. (Step S204, YES in S205). It should be noted that, in this embodiment, it is assumed that all programs included in the broadcast program information on January 20, 2020 are recorded on the HDD, so steps S204 and S205 can be skipped.

The control unit 18 checks the CSP program information stored in the CSP program information acquisition unit 102 for each program X. For the case where the CSP that provides the program X is found in the CSP program information, for example, the program A3 in FIG. 10 is taken as an example of the program X for description. As for the program A3, since the CSP1 provides the program A3, the control unit 18 selects to delete the recorded data of the program A3 from the HDD, and causes the recording and playback unit 17 to delete the recorded data (YES in step S207, S208). ). On the other hand, the case where the CSP that provides the program X is not found in the CSP program information will be described by taking the program A4 in FIG. 10 as an example of the program X, for example. As for the program A4, since there is no CSP provider that provides the program A4, the control unit 18 selects to keep the recorded data of the program A4 in the HDD (NO in step S207). After the processes from step S204 to step S208 are performed on all programs in the acquired broadcast program information, all programs are in either state provided by the CSP or stored in the HDD. The recording data management unit 104 updates the recording completion data based on this state. In addition, when this state is displayed as program information, the display is the same as that shown in FIG. 12 . However, in FIG. 12 , the program E1, the program D4, and the program F5 are examples of exceptional actions.

Through the above steps, it is possible to determine whether to delete or retain the recorded data stored in the HDD based on the CSP program information, and to delete the recorded program when it is known that the program is provided by the content server device or the like. Thereby, the usage capacity of the HDD can be reduced without losing the opportunity to watch the program. It should be noted that, in the present embodiment, the HDD update command signal from the remote controller 100 is used as a trigger for updating the HDD (step S201 ). However, for example, the control unit 18 or the like may monitor the usage capacity of the HDD and adjust the HDD according to the Use capacity of the HDD to generate a trigger to update the HDD, etc.

Variation

In the present modification, examples of other operations that can be performed in the receiving apparatus 10 shown in the present embodiment will be described.

14 is a flowchart showing an example of a processing operation for playing back the content of the CSP selected from the displayed program information in the modification. This example shows an example in which the program provided by the CSP is played from the EPG program table of the broadcast program displayed as in the program display of Fig. 10 .

When the user presses the program information display button for displaying the EPG program table from the remote controller 100, the remote controller 100 outputs a program information display command signal and program information specifying information for specifying broadcast program information such as dates. The control unit 18 of the receiving apparatus 10 acquires a program information display command (step S301).
