The broadcast sequence stores the broadcast times of the program. The broadcast date and the number of broadcasts are stored only when the content type is a program.

  Next, processing in the related information distribution system will be described. FIG. 6 is a flowchart showing the procedure of the availability information output process. The availability information output process is a process performed by the content reproduction device 1. The CPU 11 of the content reproduction device 1 reads the content (Step S11). As the content, the content recorded on the BD is read from the BD drive 182 or the recorded program recorded on the HDD 181 is read. The CPU 11 reproduces the read content (step S12). The content is output from the display device 2. The CPU 11 determines whether an instruction to display the available information has been issued (step S13). The display instruction of the available information is performed by the viewer pressing a predetermined button on the remote controller. When the button is pressed, a signal transmitted from the remote controller is received by the receiving unit 14. The CPU 11 determines whether or not the display instruction has been given by determining whether or not the received signal is a signal from the button assigned to the display instruction. When determining that the display instruction has not been given (NO in step S13), the CPU 11 repeatedly executes step S13. When determining that the display instruction has been given (YES in step S13), the CPU 11 acquires the time code (time information) of the instructed frame (step S14). The CPU 11 overlays the thumbnail screen on the display screen of the reproduced content and displays the available information in or near the thumbnail screen so that the viewer can confirm which frame of the available information is being displayed. You may. Further, the usable information may be displayed only when the reproduction of the content is temporarily stopped. Furthermore, when a display instruction is given, the reproduction may be paused and then the available information may be displayed. The CPU 11 acquires the identification information of the content (step S15). The CPU 11 converts the obtained time code and identification information into usable information (step S16). Various methods such as encoding using a predetermined encoding rule and encryption using a public key encryption method can be used for conversion into usable information. The CPU 11 reads the destination information (step S17). The transmission destination information is stored in advance in the storage unit 32 or the like. The transmission destination information is, for example, a URL. The URL corresponds to the related information providing device 4. The related information providing device 4 provides related information by a Web service. The CPU 11 outputs the available information and the destination information (step S18), and ends the processing. For example, the available information and the destination information are output as QR codes. The QR code is superimposed and displayed on the content display screen of the display device 2 as shown in FIG.

  In the above description, the viewing information, that is, the identification information and the time code are converted into the usable information. However, the conversion is not limited thereto. The viewing information and the destination information may be converted into usable information.

  Next, a process of acquiring related information using available information will be described. FIG. 7 is a flowchart showing the procedure of the related information acquisition process. The related information acquisition process is a process performed by the related information using device 3. The CPU 31 of the related information using device 3 acquires the available information and the destination information (step S21). Specifically, the viewer captures an image of the QR code displayed on the display device 2 by the content reproduction device 1 using the imaging unit 37, and the CPU 31 acquires the available information and the transmission information from the captured QR code. The CPU 31 transmits the obtained usable information to the destination indicated by the destination information (step S22). The transmission destination is the related information providing device 4 as described above. The CPU 31 receives the related information from the related information providing device 4 that is the transmission destination (step S23). The CPU 31 displays the received related information on the display unit 35 (step S24), and ends the processing.

  Note that, in the case where the viewing information and the transmission destination information are converted into usable information in the content reproduction device 1, the related information using device 3 decodes the usable information into the viewing information and the transmission destination information. Subsequently, only the viewing information is converted into usable information, and the converted usable information is transmitted to the transmission destination.

Next, the related information transmission process will be described. FIG. 8 is a flowchart showing the procedure of the related information transmission process. The related information transmission process is a process performed by the related information providing device 4. The related information providing device 4 receives the usable information from the related information using device 3 (Step S31). The CPU 41 decodes the received usable information and acquires the viewing information (step S32). The CPU 41 searches the content ID search table 422 using the identification information of the content included in the viewing information as a search key, and reads the content ID from the record that has been found in the search (step S33). The CPU 41 searches the related information database 421 using the acquired content ID and the time code included in the viewing information as a search key, and reads the related information from the record found in the search (step S34). The CPU 41 transmits the related information to the related information using device 3 (step S35), and ends the processing.

  Embodiment 1 has the following effects. The related information providing device 4 receives, from the related information using device 3, available information obtained by encoding or encrypting viewing information (including identification information for identifying contents and a time code indicating a viewing position). The related information providing device 4 acquires the viewing information from the available information and transmits the related information to the related information using device 3 based on the information. This makes it possible to prepare related information for each frame of the content and provide the related information to the viewer. Further, the content reproduction device 1 displays available information obtained by encoding or encrypting the viewing information, and causes the related information using device 3 to acquire the available information. Since the related information using device 3 transmits the available information to the related information providing device 4, it is difficult for a third party to acquire the viewing information even if the available information is leaked.

Embodiment 2
Embodiment 2 relates to a mode in which there are a plurality of related information providing devices 4. That is, there is a form in which there are a plurality of destinations of the available information. FIG. 9 is an explanatory diagram showing an example of a record layout of the transmission destination information database 121. The transmission destination information database 121 is stored in the storage unit 12 of the content reproduction device 1. The transmission destination information database 121 is a database that stores information indicating the transmission destination of the usable information. The destination information database 121 includes a destination ID column, a destination name column, and a URL column. The transmission destination ID column is a primary key and stores a value that can uniquely specify the transmission destination. The transmission destination name column stores transmission destination names. The URL column stores a URL indicating a transmission destination. Here, the URL corresponds to the related information providing device 4. The related information providing device 4 provides related information by a Web service.

  A process according to the second embodiment will be described. In the following description, points different from the first embodiment will be mainly described. The reading of the destination information in step S17 in the availability information output process shown in FIG. 6 is performed from the destination information database 121. When a plurality of pieces of destination information are read, a plurality of pieces of destination information are output in outputting the destination information in step S18. When the available information and the destination information are output in the form of a QR code, there is a limit to the amount of data that can be expressed as a QR code. You may narrow down. For example, priorities may be assigned to a plurality of transmission destinations in advance by the viewer, and when narrowing down, transmission destination information may be selected in a range from a high priority order to a data amount allowable range.

  In the related information acquisition process shown in FIG. 7, in step S22, a plurality of destinations (available information is transmitted to the related information providing device 4. As a result, in step S23, related information is transmitted from the plurality of destinations. In step S24, a plurality of related information is displayed in a list, and in the list display, a group may be displayed for each transmission destination, and a head portion of the related information is displayed as a heading in a list so that the viewer can view the list. When one piece of related information is selected, the selected related information may be displayed in full text.

  Even when there are a plurality of pieces of transmission destination information, one piece of transmission destination information may be output. At this time, the viewer may select one transmission destination in advance, and transmission destination information related to the selected transmission destination may be output from the content reproduction device 1. Also, even when there are a plurality of pieces of destination information, the viewer may be allowed to select all pieces of destination information instead of displaying all pieces of destination information. For example, each time the display instruction of the available information is instructed, the destination information may be displayed in a list and one or more destinations to be output to the viewer may be selected.

  Embodiment 2 has the following effects. Since there are a plurality of related information providing devices 4 and a plurality of destination information accordingly, a variety of related information corresponding to one frame of one content can be obtained.

Embodiment 3
Embodiment 3 relates to a mode in which a management device for managing a transmission destination is provided. FIG. 10 is an explanatory diagram illustrating a configuration example of the related information distribution system according to the third embodiment. The related information distribution system includes a content reproducing device 1, a display device 2, a related information using device 3, a plurality of related information providing devices 4A, 4B,... Since the plurality of related information providing devices 4A, 4B,... Have the same functions, the related information providing devices 4A, 4B,. Also, the functions and configurations of the content reproducing device 1, the display device 2, the related information using device 3, and the related information providing device 4 are the same as those in the first embodiment, and the description is omitted.

  The management device 5 has a role of receiving the available information from the related information using device 3 and distributing the received usable information to the related information providing device 4. FIG. 11 is a block diagram illustrating an example of a hardware configuration of the management device 5. The management device 5 includes a CPU 51, a storage unit 52, a RAM 53, and a communication unit 54. The functions of the CPU 51, the RAM 53, the communication unit 54, and the like are the same as those of the CPU 41, the RAM 43, and the communication unit 44 of the related information providing device 4 described above, and thus description thereof will be omitted. The storage unit 52 is, for example, a hard disk or an SSD. The storage unit 52 stores various data required when the CPU 51 performs processing, such as a program 52P and a distribution site database (distribution site DB) 521.

  FIG. 12 is an explanatory diagram showing an example of a record layout of the distribution site database 521. The distribution site database 521 is a database for the related information providing device 4 functioning as a Web site. The distribution site database 521 includes a site ID column, a destination name column, a provider ID column, a URL column, and a genre column. The site ID column is a primary key and stores an ID for uniquely specifying a distribution site. The transmission destination name column stores the name of a Web site realized by the related information providing device 4. The provider ID column stores the ID of a provider who provides related information by the related information providing device 4. The URL column stores a URL for accessing the distribution site. The genre column stores the genre of the distribution site.

FIG. 13 is a flowchart illustrating a procedure of a related information acquisition process according to the third embodiment. The related information acquisition process is a process performed by the related information using device 3. In the third embodiment, it is assumed that the program 32P for performing the related information acquisition process is provided by the provider of the related information providing device 4. The program 32P includes a provider ID indicating a provider and an encryption key for transmitting encrypted data to the related information providing device 4.
The CPU 31 of the related information using device 3 acquires the available information and the destination information (step S21). In the third embodiment, the transmission destination does not indicate the related information providing device 4 but indicates the management device 5. Since the management device 5 is uniquely determined, the program 32P may include destination information. The CPU 31 encrypts the available information using the encryption key (step S25). The CPU 31 transmits the encrypted usable information and the provider ID to the management device 5 specified by the destination information (step S26). The CPU 31 receives the related information from the related information providing device 4 (Step S23). The related information providing device 4 is a device corresponding to the provider ID. The CPU 31 displays the received related information on the display unit 35 (step S24), and ends the processing.

  Next, processing performed by the management device 5 will be described. FIG. 14 is a flowchart showing the procedure of the related information transfer process. The CPU 51 of the management device 5 receives the available information and the provider ID from the related information using device 3 via the communication unit 54 (Step S41). The CPU 51 acquires the distribution site corresponding to the provider ID, that is, the URL of the related information providing device 4 from the distribution site database 521 (step S42). The CPU 51 causes a redirect to the related information providing device 4 indicated by the acquired URL (step S43). At this time, the available information is transferred to the related information providing device 4. By being redirected, the related information using device 3 communicates with the related information providing device 4 and can obtain the related information. Note that the related information transmission process performed by the related information providing device 4 is substantially the same as the process illustrated in FIG. The differences are as follows. The CPU 41 of the related information providing device 4 receives the encrypted usable information (step S31). The CPU 41 decrypts the encrypted usable information. Then, the decrypted usable information is further decrypted to obtain the viewing information (step S32). Thereafter, the same applies.

  Note that the related information using device 3 encrypts the obtained usable information, but the present invention is not limited to this. After decrypting the available information into the viewing information, the viewing information may be encrypted and transmitted to the management device 5 as the available information. In this case, the redirected related information providing device 4 decrypts the encrypted usable information and acquires the viewing information.
