Hereinafter, embodiments of the present invention will be further described with reference to the drawings.
1. Schematic configuration of the device:
FIG. 1 is a block diagram illustrating an outline of a broadcast receiving apparatus 11 according to the embodiment. The broadcast receiving device 11 may be referred to as digital television. As shown in FIG. 1, the broadcast receiving apparatus 11 supplies a digital broadcast signal received by an antenna 12 to a tuner unit 14 via an input terminal 13, thereby transmitting a broadcast signal (contents such as a program) of a user desired channel. (Broadcast signal for broadcasting) is selected and received.

  The broadcast receiving apparatus 11 supplies the demodulator 15 with the broadcast signal selected by the tuner unit 14 and demodulates it. The descrambler unit 16 decrypts the encryption as necessary, and then sends it to the demultiplexer unit 17. Output. The demultiplexing unit 17 separates the broadcast signal output from the descrambler unit 16 for each type, and the separated video signal and audio signal (video signal and audio signal constituting the content) are converted into a video / audio decoder 18. Output to. The video / audio decoder 18 decodes the separated video signal and audio signal, outputs the video signal to the synthesis processing unit 19, and outputs the audio signal to the audio processing unit 20. The synthesis processing unit 19 can superimpose and output another image on the video signal supplied from the video / audio decoder 18 by OSD (On Screen Display).

  The broadcast receiving apparatus 11 supplies the video signal output from the synthesis processing unit 19 to the video processing unit 22. The video processing unit 22 converts the input video signal into an analog video signal in a format that can be displayed on the video display unit 23 having, for example, a liquid crystal panel. The broadcast receiving apparatus 11 supplies the analog video signal output from the video processing unit 22 to the video display unit 23 for video display. The audio processing unit 20 converts the input audio signal into an analog audio signal in a format that can be reproduced by the speaker 24. The analog audio signal output from the audio processing unit 20 is supplied to the speaker 24 for audio reproduction.

  The broadcast receiving apparatus 11 includes a control unit 30 that comprehensively controls all the operations including the reception operation described above. In the control unit 30, the CPU controls the operation of the broadcast receiving apparatus 11 by executing a control program stored in the ROM or the like using the RAM or the like as a work area. Furthermore, the broadcast receiving apparatus 11 includes a storage unit 31 for storing content. The storage unit 31 is configured by a storage medium such as a hard disk drive (HDD). The control unit 30 causes the storage unit 31 to record the content superimposed on the broadcast signal received by selecting the tuner unit 14, that is, according to a predetermined format including a video signal and an audio signal constituting the content. A moving image file can be stored in the storage unit 31.

  The control unit 30 can execute processing according to a control signal for remote operation from a remote controller (hereinafter referred to as a remote controller) operated by a user. That is, the control unit 30 provides the content for real-time viewing by causing the video / audio decoder 18 to output the content superimposed on the currently broadcasted broadcast signal in accordance with the control signal. The content stored in the storage unit 31 is output to the video / audio decoder 18 to reproduce the content (the video related to the content is displayed on the video display unit 23 and the audio related to the content is Output from the speaker 24).

  In this way, the user can view the content that the broadcast receiving apparatus 11 receives the broadcast in real time, or record it and view it later (time-shifted viewing). In the following, in the present embodiment, description will be made mainly regarding storage (recording) of content in the storage unit 31 using a preference list and list display of stored content. Further, the content to be recorded in the storage unit 31 in this embodiment may be a program broadcast on a general television broadcast channel such as terrestrial, BS, CS, etc., but these general television broadcasts are performed. A program broadcast by a specific operator during a time zone in which the radio wave band is free, such as late at night or early morning, may be assumed.

  A network interface 28 (communication unit) is connected to the control unit 30. The network interface 28 is connected to the network 29 via input / output terminals. The network 29 is, for example, a wireless LAN constructed under a router installed in a home or office. As shown in FIG. 1, a plurality of operation terminals 40 (operation terminals 40a, 40b, and 40c) are wirelessly connected to the network 29 so that they can communicate with each other. The operation terminal 40 is an example of an operation device that remotely operates an external device. When viewed from the operation terminal 40, the broadcast receiving device 11 corresponds to an example of an external device. Conversely, when viewed from the broadcast receiving device 11, the operation terminal 40 corresponds to an example of an external device. The broadcast receiving apparatus 11 and the plurality of operation terminals 40 can identify and recognize each other as devices on the network 29 based on, for example, the MAC address. The operation terminal 40 is a terminal operated by a user, and each functions as a remote control for the broadcast receiving apparatus 11.

  The operation terminal 40 may be any device that can remotely control the broadcast receiving device 11. For example, a laptop PC, a tablet terminal, a smartphone, or the like is assumed. Such an operation terminal 40 includes a control unit 41, a communication unit 42, and a storage unit 43. The communication unit 42 is an interface that can communicate with an external device. In the control unit 41, the CPU controls the operation of the operation terminal 40 by executing a program stored in the ROM or the like using the RAM or the like as a work area. The control unit 41 is equipped with a dedicated program (application AP) for remotely operating the broadcast receiving device 11, and the operation terminal 40 can be operated arbitrarily by the user in a situation where the application AP is activated. Accordingly, the broadcast receiving apparatus 11 is remotely operated through the communication unit 42 and the network 29. The broadcast receiving apparatus 11 and the operation terminal 40 can be connected to an external network (Internet) via the network 29. In other words, the broadcast receiving device 11 and the operation terminal 40 also have a function of browsing information on the Internet. The means for realizing the wireless communication between the operation terminal 40 and the broadcast receiving apparatus 11 is not limited to the wireless LAN, and various communication standards such as Bluetooth (Bluetooth (registered trademark)), ZigBee, and infrared communication are adopted. Is possible.

2. User registration process:
FIG. 2 is a flowchart showing an example of user registration processing in the system according to the present embodiment (a system including the broadcast receiving apparatus 11 and one or more operation terminals 40). In FIG. 2, both the process on the broadcast receiving apparatus 11 side and the process on the operation terminal 40 side are described for simplicity of explanation.

  The control unit 30 accepts registration of a plurality of users participating in the system (step S100). Specifically, the user inputs the user (user name) after placing the broadcast receiving apparatus 11 in the user registration mode by a direct operation on the broadcast receiving apparatus 11 or an operation using a remote controller. The control unit 30 receives an input of a user name and registers it in a predetermined storage medium. Thus, a registered user name list (user name list) is generated. Here, as an example, a description will be given assuming that a user name list in which four user names of users A, B, C, and D are registered is generated.

The user name is an example of identification information in the present invention. That is, the user name is information for identifying the user. In addition to the user's actual name, the user name may be a nickname, abbreviation, or any other unique character string associated with the user. The user name may be called a user ID or the like.
Next, the control unit 30 distributes the user list generated in step S100 to a remote controller (a plurality of operation terminals 40 illustrated in FIG. 1) that can be recognized via the network 29 (step S110). In the operation terminal 40 that has received the distribution of the user list, the storage unit 43 stores the user list.

  The control unit 41 of the operation terminal 40 that has received the distribution of the user list associates the user name on the user list with the individual user who operates the operation terminal 40, thereby determining the user who operates the operation terminal 40. Register (step S120). Specifically, the operation terminal 40 has a personal recognition function such as input of a unique password for each individual and personal authentication (for example, biometric authentication such as face authentication, fingerprint authentication, voiceprint authentication, iris authentication, etc.). The user who operates the operation terminal 40 is recognized. Then, the personal recognition result of the user and the user name selected from the user name list by the operation by the user are associated and stored in a predetermined storage medium.

  For example, when the user A operates the operation terminal 40a (see FIG. 1) and selects his / her user name (user A) from the user name list of the operation terminal 40a, the operation terminal 40a recognizes the user A as a person. Is associated with the selected user name (user A), and the associated result (user registration information) is stored. Similarly, it is assumed that the operation terminal 40b stores user registration information of the user B who operates the operation terminal 40b. Similarly, it is assumed that the operation terminal 40c stores user registration information of the user C who operates the operation terminal 40c and user registration information of the user D who operates the operation terminal 40c. That is, although the operation terminal 40 may be shared by a plurality of users, the operation terminal 40 has user registration information for each user who shares the operation terminal 40.

  Thereafter, the operation terminal 40 always recognizes the user individually and stores it in the user registration information in association with the result of the individual recognition when executing any transmission to the broadcast receiving apparatus 11 in response to the user's operation. A user name is specified, and information with the specified user name added is transmitted. As described above, in the operation terminal 40, the storage unit 43 stores the identification information acquired by communication from the external device (method receiving apparatus 11), and the control unit 41 stores the specific identification information in the stored identification information. The added instruction information is transmitted to the external device (method receiving device 11). Accordingly, the broadcast receiving apparatus 11 that has received the transmission from the operation terminal 40 refers to the user name added to the received information (the user name added to the received information is any one in the user name list). It is possible to identify from which user (user A, B, C, or D) the transmission is made.

3. Explanation about personal preference list:
As described above, the user operates the remote controller, that is, the operation terminal 40 to cause the broadcast receiving apparatus 11 to select a broadcast so that the content of a desired channel can be viewed in real time, or the content stored in the storage unit 31 can be viewed. The stored content can be viewed and viewed (time-shifted viewing). In this embodiment, the control unit 30 adds a viewing instruction (viewing a channel selection instruction or a stored content reproduction instruction) related to content viewing from any of the operation terminals 40 to the viewing instruction. By creating a list of associated user names and attribute information of content that has been viewed (reproduced) according to the viewing instruction, a preference list (individual preference list) for each user is generated and managed. . The personal preference list is an example of a first list. In this sense, the control unit 30 manages the first list in which the identification information added to the instruction information from the external device (the operation terminal 40) is associated with the attribute information of the content reproduced based on the instruction information. It can be said that it also functions as a department.

FIG. 3 is a flowchart showing a personal preference list management method executed by the control unit 30.
The control unit 30 continuously monitors whether or not there is a content viewing instruction from any of the operation terminals 40 (step S200), and when there is a content viewing instruction, In response to the viewing instruction, control processing necessary for real-time viewing or time-shifted viewing of the content is executed, and the content desired by the user is viewed (step S210).

  The control unit 30 specifies the user who has instructed the operation terminal 40 to transmit the content viewing instruction and the genre of the content to be viewed in step S210 in accordance with the content viewing instruction (step S220). The content genre is a kind of the attribute information. Since the user's name of the user who instructed the operation terminal 40 to transmit is added to the content viewing instruction, the control unit 30 sends the user name to the operation terminal 40 to transmit the content viewing instruction. Specify as the instructing user.

  The broadcast signal includes program related information (SI / PSI) such as media information and program information in addition to the video signal and the audio signal. This program-related information is separated by the separation (Demux) unit 17 and is interpreted by the control unit 30. Such program-related information (content attribute information) includes genre information (for example, EIT (Event Information Table)) of the program, that is, the content. When the content is stored in the storage unit 31, such program-related information is described in, for example, a header of the stored content (moving image file). For this reason, the control unit 30 stores specific content according to the viewing instruction (content reproduction instruction) even when the broadcast signal is received according to the viewing instruction (channel selection instruction) and the content is directly viewed in real time. Even when the data is read from the unit 31 and used for reproduction, it is possible to specify the genre of the content that has been viewed in step S210.

The control unit 30 updates the current personal preference list with the user and genre information specified in step S220 (step S230).
FIG. 4 shows an example of a personal preference list that the control unit 30 stores in association with each user name on the user name list. Here, as an example, a personal preference list PLA associated with the user A, a personal preference list PLB associated with the user B, and a personal preference list PLC associated with the user C are shown. The personal preference list includes genre, number of times, and date / time as items. The genre is the genre of the content viewed by the user in the broadcast receiving device 11 in accordance with the viewing instruction, the number of times is the number of times of reproduction so far (number of times of viewing instruction, etc.) for each genre, Playback date and time (date and time of viewing instruction, etc.).

  For example, it is assumed that the control unit 30 specifies the information of the user A and the genre “report” according to the content reproduction instruction transmitted from the operation terminal 40a. In this case, in step S230, the control unit 30 adds 1 to the current count of the genre “report” in the personal preference list PLA of the user A, and sets the current date and time of the genre “report” in step S210. It is rewritten to the date and time when it was played (for example, the date of what year, month, day). At this time, if the genre “report” is not included in the personal preference list PLA of the user A, the control unit 30 adds “report” to the genre in the personal preference list PLA and also adds the added genre “report”. Enter the number of times (one time) and the date and time corresponding to "". Such a flowchart shown in FIG. 3 is executed while the broadcast receiving apparatus 11 is activated, so that the personal preference list of each user is updated as needed.

  The above-described personal preference list is not only generated and updated in response to content viewing instructions, but may also be updated in response to user operations other than viewing instructions. For example, the control unit 30 adds a word acquired by communication from an external device different from the viewing instruction to the genre in the personal preference list. A user's operation other than the viewing instruction corresponds to a search performed by the user on the Internet. That is, when the browser installed in the operation terminal 40 performs a search on the Internet by the user's operation, the operation terminal 40 displays the word input by the user for the search together with the user name. Send to. At this time, when a phrase including a plurality of words is input for the search, the operation terminal 40 appropriately divides the phrase into words, and transmits the divided words to the broadcast receiving device 11.

FIG. 5 is a flowchart showing a personal preference list management method executed by the control unit 30 and that can be executed in parallel with the process shown in FIG.
The control unit 30 continuously monitors through the network interface 28 whether any of the operation terminals 40 has transmitted a word (word information based on character data) associated with a predetermined command different from the viewing instruction. (Step S300). When such a word is transmitted, the control unit 30 specifies the user (user name) who has instructed the operation terminal 40 to perform the transmission (step S310). Then, the control unit 30 updates the personal preference list stored in association with the user name specified in step S310 with the word determined to have been transmitted in step S300 (step S320).

  In step S310, it is assumed that the control unit 30 specifies the user C in response to the transmission of the word “comed” from the operation terminal 40c, for example. In this case, in step S320, the control unit 30 adds 1 to the current number of genres “comed” in the personal preference list PLC of the user C, and sets the current date and time of the genre “comed” to the word in step S300. Is rewritten to the date and time when it is determined that there is a transmission (for example, the date of what year, month, day). Also in this case, if the genre “comed” is not included in the personal preference list PLC of the user C, the control unit 30 adds “comed” to the genre in the personal preference list PLC and also adds the added genre “ Enter the number of times corresponding to "Comedy" (once) and the date and time.

  While the word input by the user when performing a search using the operation terminal 40 is arbitrary, the genre of content that can be included in the personal preference list is limited to some extent. For example, a genre defined in a genre dictionary defined by ARIB (Radio Industry Association) standard is a genre that can be included in the personal preference list (and a common preference list described later). Therefore, in step S320, the control unit 30 converts the word (word information) determined to have been transmitted in step S300 into a predetermined word representing the genre of the content, and the converted word is used to convert the individual word. The genre in the preference list may be added or updated. For example, the broadcast receiving apparatus 11 includes a conversion engine (database and conversion program) that converts an input word into a word representing a genre that is presumed to be most relevant to the word, and uses the conversion engine. The word conversion is performed.

  Thereby, for example, when the word input to the operation terminal 40 by the user for the search is the comedian's personal name, the genre of the content that can be included in the personal preference list as a conversion result by the conversion engine. It is converted into the word “comedy”. Note that word conversion using the conversion engine may be performed on the operation terminal 40 side. When the operation terminal 40 performs word conversion using the conversion engine, the converted word is transmitted from the operation terminal 40 to the broadcast receiving device 11 (control unit 30). Alternatively, when considering the size of resources necessary to hold the conversion engine, the conversion engine may exist in a server on the Internet. In other words, the broadcast receiving device 11 and the operation terminal 40 may convert the word by using the function of the conversion engine by accessing the server via the Internet.

  Moreover, the control part 30 performs the process which reviews the content of the personal preference list for every user regularly or irregularly. For example, the control unit 30 deletes a genre from the personal preference list for a genre that is not updated for a predetermined period or more (for example, six months or more) in the individual preference list. By performing such deletion, the contents of the personal preference list can be kept in a state in which the recent preferences of the associated user are appropriately reflected.

4). Explanation about common preference list:
FIG. 6 is an example of the common preference list IL generated by the control unit 30. The control unit 30 generates and manages a common preference list that is a list in which such individual preference lists for a plurality of user names are collected. The common preference list is an example of a second list. In this sense, it can be said that the control unit 30 also functions as a management unit that manages a second list in which attribute information included in a plurality of first lists is collected. The common preference list IL is a list in which all are generated when the control unit 30 has the personal preference lists PLA, PLB, and PLC illustrated in FIG. 4 as the personal preference list. Therefore, the common preference list also includes the genre, the number of times, and the date and time as items, like the personal preference list.

  In the common preference list, information on the same genre that is included in different personal preference lists is collected. That is, for each content genre, the control unit 30 generates a common preference list that records the number of times of reproduction (number of times of viewing instructions and the like) and the latest reproduction date and time (date and time of viewing instructions and the like). For example, the genre “Japanese drama” exists in both personal preference lists PLA and PLB (see FIG. 4). Therefore, in the common preference list IL, for the genre “Japanese drama”, the number of times is described in the personal preference list PLA (8 times) and the number of times described in the personal preference list PLB (5 times). The date and time is the date and time described in the personal preference list PLA (February 15, 2015) and the date and time described in the personal preference list PLB (March 8, 2015). The date and time of the newer (March 8, 2015).

  There are various timings at which the control unit 30 generates the common preference list based on the personal preference list. For example, the control unit 30 generates a common preference list based on each latest personal preference list at the time when the content broadcast schedule (program guide, EPG) is acquired. The content broadcast schedule is, for example, data describing a schedule of content broadcast on each channel during a predetermined number of days after the present and information related to each content (information such as genre), and is periodically or indefinite. Periodically, it is broadcast superimposed on the broadcast signal. In the process in which the broadcast receiving device 11 receives a broadcast signal, such a broadcast schedule is separated from the separation (Demux) unit 17 and acquired by the control unit 30.

  The control unit 30 stores the content by controlling the driving of the tuner 14 and the storage unit 31 based on the common preference list. Specifically, the control unit 30 specifies the genre priority based on the number of times and / or the date and time recorded in the common preference list. Here, a case will be described as an example where the date and time is given the highest priority, and then the number of times is taken into consideration (if necessary). According to the common preference list IL illustrated in FIG. 6, the genres “elementary school student”, “anime”, “education”, and “Japanese drama” corresponding to the newest date (March 8, 2015) are given the highest priority. Genre (first priority genre group). Similarly, the genres “report” and “politics” corresponding to the next new date and time (March 3, 2015) are the genres that are prioritized after the first priority genre group (second priority genre group). Then, the genre “Comedy” corresponding to the next new date and time (February 6, 2015) is the genre (third priority genre group) prioritized after the second priority genre group (hereinafter the same). Repeat the idea).

  The control unit 30 specifies the priority order among the genres belonging to the same priority genre group according to the number of times. For example, if the genre is in the first priority genre group described above, “elementary school student” (84 times), “animation” (66 times), “education” (in order of decreasing number of times recorded in the common preference list IL ( 58) and “Japanese drama” (13). Similarly, in the case of a genre in the second priority genre group, the priority order is “report” (10 times) and “politics” (2 times) in descending order of the number of times recorded in the common preference list IL ( The same idea is repeated below). As a result, the control unit 30 can specify priorities among all genres included in the common preference list.

  The content is stored in accordance with the priority order specified in this way. The storage unit gives priority to the content corresponding to the genre having the higher priority order among the contents whose broadcast schedule is described in the broadcast schedule acquired as described above. This means that the data is stored in 31 or recorded. From the viewpoint of the capability of the tuner 14 and the free capacity of the storage unit 31, such a priority order is unnecessary if all the contents of all the channels whose broadcast schedule is described in the broadcast schedule can be recorded. . When the priority order is unnecessary, the control unit 30 may store, in the storage unit 31, content corresponding to the genre recorded in the common preference list among the content described in the broadcast schedule in the broadcast schedule. However, on the premise that there is a limit to the number of channels that can be recorded at the same time, and the free capacity of the storage unit 31 is also limited, in this embodiment, the priority order is set for the genre of the content to be stored as described above. It is good. As a result, the content corresponding to the genre having the higher priority is stored in the storage unit 31 with a higher probability. Moreover, it can be said that the above description shows the content storage method by the broadcast receiving apparatus 11.

5. List content:
FIG. 7 is a flowchart showing content list display control processing executed by the control unit 30.
The control unit 30 continuously monitors through the network interface 28 whether or not a list display instruction for instructing to display a list of stored contents has been transmitted from any one of the operation terminals 40 (step S400). . When the list display instruction is transmitted, the control unit 30 specifies the user (user name) who instructed the operation terminal 40 to perform the transmission (step S410).

  And the control part 30 extracts the title of a content from the content preserve | saved at the memory | storage part 31 based on the personal preference list memorize | stored in association with the user name specified by step S410 (step S420). Specifically, the titles about the content corresponding to the genre included in the personal preference list stored in association with the user name specified in step S410 are preferentially extracted. For example, in step S410, when the user who instructed the operation terminal 40 to transmit the list display instruction is identified as the user B, in step S420, the control unit 30 stores a large number of contents stored in the storage unit 31. Among them, titles about contents corresponding to the genres included in the personal preference list PLB (see FIG. 4) are extracted.

  Next, the control unit 30 generates image data representing a list of titles of the content extracted in step S420, and outputs the image data to the composition processing unit 19, whereby an image based on the image data, that is, the extraction A list of the titles thus displayed is displayed on the video display unit 23 (step S430). In executing such processing, the control unit 30 extracts the title of content whose attribute information (genre) matches the attribute information (genre) in the first list from the stored content, and extracts the title. It can be said that it functions as at least a part of a display control unit that displays a list on a predetermined display unit. If the number of content titles extracted in step S420 is larger than the number of content titles that can be displayed in a list at a time (for example, 10 titles) in the screen of the video display unit 23, the control unit 30 performs a screen scroll operation. All the extracted titles can be browsed. In this case, the control unit 30 places the content related to the genre having a high priority level (for example, the priority level that can be determined based on the newness of the date and the number of times in the personal preference list) at the top of the scrolled screen. Image data in which titles are preferentially arranged may be generated.

6). Summary:
As described above, according to the present embodiment, the operation of each user who uses the broadcast receiving device 11 by operating the operation terminal 40 (viewing instruction, search operation on the Internet unrelated to the viewing instruction, etc.) is performed. Reflecting this, a personal preference list in which the preference of the content genre for each user is recorded is generated. Then, based on a common preference list in which such personal preference lists are collected for a plurality of users, storage of content in the storage unit 31 by the broadcast receiving device 11 is executed. As a result, the optimum content selection (selection of content to be stored) is performed in consideration of the preferences of a plurality of users, and the convenience and comfort of each user who wants to view the stored content is comprehensive. To improve.

  Further, according to the present embodiment, the broadcast receiving apparatus 11 receives the content list display instruction from the user, based on the personal preference list associated with the user, the content stored in the storage unit 31. Extract the content title from the list and display it in a list. As a result, the user accurately browses the content of the genre that suits his / her preference in a situation where the content related to various genres including the genre that matches the preference of the user other than himself / herself is stored in the storage unit 31. be able to. Therefore, it is possible to easily select a content to be viewed from the stored content.

  In the above description, when specifying the priority order of the genre of the content to be stored based on the common preference list, the example in which the date and time for each genre in the common preference list is given priority over the number of times has been described. The number of times may be given priority over the date and time.

  The control unit 30 may apply a weight for each user when generating a common preference list by collecting a plurality of personal preference lists. The user can arbitrarily set a weight between users for the broadcast receiving apparatus 11. As an example, assume that higher weights (weighting factors) are set in the order of user A, user B, and user C. The control unit 30 corrects each personal preference list according to the weight, and generates a common preference list based on each corrected personal preference list. For example, the personal preference list PLA associated with the user A is corrected by multiplying the number of times for each genre by the weighting factor of the user A. Similarly, the personal preference list PLB associated with the user B is corrected by multiplying the number of times for each genre by the weight coefficient of the user B, and the number of times for each genre for the personal preference list PLC associated with the user C. Is multiplied by the weighting factor of user C to correct. The control unit 30 may correct the date and time for each genre in the personal preference list to a new date and time as the weight set for the associated user name is higher. According to such a configuration, when the control unit 30 specifies the priority order of the genre based on the common preference list, the genre preferred by the user with the higher weight is more likely to be prioritized, and the weight is set. Can be along.

Content attribute information is not limited to a genre. For example, instead of the content genre, various information such as performers, broadcast stations, broadcast time zones, and the like regarding the content can be used as examples of the attribute information.
The broadcast receiving apparatus 11 is not limited to digital television. The broadcast receiving apparatus 11 is embodied by an apparatus having a function capable of receiving a broadcast signal on which content is superimposed and storing the content. The broadcast receiving device 11 may be, for example, an HDD recorder, a tuner, a set top box, or the like. However, when the broadcast receiving device 11 itself is a product that does not have a monitor (video display unit 23) or a speaker 24, the broadcast receiving device 11 is used as another device for viewing the received content for the user. It is necessary to output content data (video signal and audio signal). For example, when the operation terminal 40 downloads content stored in the broadcast receiving device 11 from the broadcast receiving device 11, the user can view the content through the operation terminal 40.
