Hereinafter, embodiments of the present invention will be described.
<Configuration>
FIG. 1 is a diagram showing a configuration of an information processing system 1 according to an embodiment of the present invention. The information processing system 1 includes a metadata providing device 10, an advertisement metadata storage device 20, a communication terminal 30, a program metadata storage device 40, a receiver 50, and a plurality of broadcasting stations 60. In the information processing system 1, there may be a plurality of communication terminals 30 and receivers 50. However, in FIG. 1, only one of each is shown for convenience of explanation. The network NW is a line for transmitting information, such as the Internet, an intranet, or a mobile communication network. This network NW is between the metadata providing apparatus 10 and the advertisement metadata accumulating apparatus 20, between the metadata providing apparatus 10 and the program metadata accumulating apparatus 40, and between the metadata providing apparatus 10 and the communication terminal 30. Connect each.

  Each broadcasting station 60 transmits broadcast data indicating sound, video, and the like as a broadcast wave by television broadcasting. This broadcast data includes program broadcast data representing a program, advertisement broadcast data representing each advertisement inserted into the program, and a channel number of the broadcast wave. Hereinafter, data representing an advertisement is referred to as “advertisement broadcast data”, and data representing a program is referred to as “program broadcast data”. The channel number is a number assigned in advance to each broadcasting station 60 in order to distinguish broadcast data transmitted from each broadcasting station 60. In the following description, transmission of broadcast data by the broadcast station 60 may be referred to as “broadcast”. Further, the advertisement broadcast data transmitted from the broadcast station 60 may be referred to as “advertisement”, and the program broadcast data transmitted from the broadcast station 60 may be referred to as “program”.

  FIG. 2 is a schematic diagram for explaining the contents of broadcast data transmitted by the broadcast station 60. In FIG. 2, the advertisement broadcast data and the program broadcast data are arranged in the order of transmission along the time axis T. The broadcast station 60 transmits the advertisement broadcast data A and the advertisement broadcast data B in one continuous time zone between the date T1 when transmission of the program broadcast data Z1 is completed and the date T4 when transmission of the program broadcast data D1 is started. In addition, the advertisement broadcast data C is transmitted, and in one continuous time zone between the date T6 when transmission of the program broadcast data D2 is completed and the date T9 when transmission of the program broadcast data Z2 is started. Broadcast data E, advertisement broadcast data F, and advertisement broadcast data G are transmitted. More specifically, the broadcast station 60 transmits the program broadcast data Z1 until the date and time T1, transmits the advertisement broadcast data A from the date and time T1 to the date and time T2, and transmits the advertisement broadcast data B from the date and time T2 to the date and time T3. The advertisement broadcast data C is transmitted from date T3 onward to date T4. The broadcast station 60 also has program broadcast data D1 that is one corner of program broadcast data D from date T4 to date T5, and program broadcast data D2 that is one corner of program broadcast data D from date T5 to date T6. Is sending. This corner is obtained by dividing a program into several groups, for example, news related to topics such as “sports” news in news programs and “weather forecast” news. The broadcast station 60 transmits the advertisement broadcast data E from the date and time T6 to the date and time T7, transmits the advertisement broadcast data F from the date and time T7 to the date and time T8, and transmits the advertisement broadcast data G from the date and time T8 to the date and time T9. The program broadcast data Z2 is transmitted from the date and time T9. It is assumed that 13 is assigned as a channel number to the broadcasting station 60 that transmits these advertisement broadcast data and program broadcast data.

Here, the description returns to FIG. The advertisement metadata storage device 20 is a computer including storage means such as a hard disk device, and stores advertisement broadcast data metadata transmitted from each broadcasting station 60. The metadata of the advertisement broadcast data represents the attribute of the advertisement, and is referred to as “advertisement metadata” in the following description.
FIG. 3 is a diagram illustrating an example of a table in which advertisement metadata is described. The table shown in FIG. 3 includes fields of “advertisement ID”, “company name”, “product name”, “title”, “performer”, “BGM”, and “genre”. In the “advertisement ID” field, an ID for identifying each advertisement broadcast data transmitted by the broadcasting station 60 is described. In the “company name” field, the name of the advertiser is described. In the “product name” field, the name of the advertised product or service is described. The title of the advertisement broadcast data is described in the “title” field. In the “performer” field, the name of the performer appearing in the video of the advertisement broadcast data is described. In the “BGM” field, the name of the music included in the sound of the advertisement broadcast data is described. In the “genre” field, products and services to be advertised are classified into those having common properties and forms according to a certain standard, and a set of each is described. For example, the advertisement metadata with the advertisement ID C001 includes “A food” as the company name, “A curry” as the product name, “Summer curry” as the title, “A Taro” as the performer, “BGM1” as the BGM, "Food" is included as a genre.

  Further, the advertisement metadata storage device 20 stores the feature points of the advertisement broadcast data indicated by the advertisement ID in association with the advertisement ID. This feature point represents a video or audio feature of the advertisement broadcast data so that each advertisement broadcast data can be identified. For example, the feature point is data representing a characteristic attribute such as a frequency characteristic of the audio. Since the content of the advertisement broadcast data is known before the broadcast, the advertisement metadata storage device 20 may store the feature points of the advertisement broadcast data provided from the broadcast station. Then, the advertisement metadata storage device 20 uses, for example, a hidden Markov model, a hash method, or the like to store the feature points of the advertisement broadcast data stored before the broadcast and the sound feature points of the advertisement broadcast data being broadcast. When the number or ratio of common feature points exceeds a predetermined value by using a known voice recognition technology using the above, the broadcast advertisement data being broadcast corresponds to pre-stored advertisement broadcast data to decide. That is, the advertisement metadata storage device 20 stores this feature point in order to recognize which advertisement broadcast data is being broadcast.

  Here, the description returns to FIG. The program metadata storage device 40 is a computer having storage means such as a hard disk device, for example, and stores metadata of program broadcast data transmitted from each broadcasting station 60. In the following description, the metadata of program broadcast data is referred to as “program metadata”. Specifically, the program metadata is information indicating the attributes of the program according to the program broadcast data, and is information stored in the program metadata storage device 40 after the program is broadcast. That is, the advertisement metadata is stored in the advertisement metadata storage device 20 before the broadcast, whereas the program metadata is stored in the program metadata storage device 40 after the broadcast. This program metadata is obtained by a person such as an operator who is resident in a facility where the program metadata storage device 40 is installed actually watching a program being broadcast on a receiver (not shown) in the facility, and at the same time. This information is input to the program metadata storage device 40 while checking information related to the contents. In this way, humans such as operators create program metadata while watching broadcasts. For example, what is called a live broadcast is broadcast on which date each content constituting the program is broadcast until the program is actually broadcast. There are many cases where the user does not know, and the content of the program itself is not determined until it is actually broadcast, and it is cumbersome to create the program metadata by examining all the program contents before broadcasting by. The person who creates the program metadata is not limited to a specific person such as an operator, but may be any person who views the program via the receiver.

FIG. 4 is a diagram showing an example of a table in which program metadata is described.
The table shown in FIG. 4 includes fields of “channel number”, “program ID”, “program title”, “corner ID”, “corner title”, “detailed information”, “start date / time”, and “end date / time”. have. In the “channel number” field, a channel number assigned to the broadcasting station 60 that transmitted the program broadcast data is described. In the “program ID” field, an ID for identifying each program broadcast data is described. In the “program title” field, the title of the program corresponding to the program broadcast data is described. In the “corner ID” field, an ID for identifying each corner constituting the program is described. In the “corner title” field, the title of the corner is described. The contents of the corner are described in the “detailed information” field. In the “start date and time” field, the start date and time of the corner is described. The “end date and time” field describes the end date and time of the corner.

  In the program metadata of FIG. 4, the program ID of the program broadcast data D transmitted by the broadcasting station 60 with the channel number “13” from the date after T4 to the date T6 is “BA001”, and the program title is “Tonight "News". Further, in this program metadata, the corner ID of one corner (program broadcast data D1) transmitted from the broadcast station 60 after the date T4 to the date T5 is “BC001”, the corner title is “sports”, and the details. It is shown that the information is “Today's professional baseball game result ...”. Also, in this program metadata, the corner ID of one corner (program broadcast data D2) transmitted from the broadcast station 60 from the date T5 to the date T6 is “BC002”, the corner title is “weather forecast”, It is shown that the detailed information is “Tomorrow's weather in the Kanto region ...”. That is, the program ID of the program broadcast data D shown in FIG. 2 is BA001, the corner ID of the program broadcast data D1 is BC001, and the corner ID of the program broadcast data D2 is BC002.

  Here, the description returns to FIG. The receiver 50 receives broadcast data transmitted from the broadcast station 60 and reproduces a program and an advertisement corresponding to the broadcast data.

When the CPU of the control unit 310 uses the RAM as a work area and executes a program stored in the ROM, the storage unit 320, or the like, the operation of each unit of the communication terminal 30 is controlled. In the RAM of the control unit 310, a subscriber number assigned to the communication terminal 30 which is a mobile phone is read from a SIM (Subscriber Identity Module) (not shown) and stored. This subscriber number is used as a user ID for identifying each user who uses the information processing system 1, that is, each user who carries the communication terminal 30. The storage unit 320 includes, for example, a flash memory, and stores various programs and data. The communication unit 330 includes a wireless interface, and transmits / receives data to / from other communication terminals 30 and the metadata providing apparatus 10 via the network NW. The display unit 340 includes, for example, a liquid crystal display and a liquid crystal driving circuit, and displays an image corresponding to data supplied from the control unit 310. The clock unit 350 has a function of measuring the date and time, and supplies the measured date and time to the control unit 310. The operation unit 360 includes operators such as a plurality of keys and a touch screen, and supplies an operation signal corresponding to a user operation to the control unit 310.

  Here, the description returns to FIG. The metadata providing apparatus 10 is a computer that is interposed between the broadcasting station 60 and the communication terminal 30 and performs information processing for supporting browsing of the user's program metadata and advertisement metadata. Supporting the viewing of the user's program metadata and advertisement metadata means that the user can easily view the program metadata and advertisement metadata displayed on the display unit 340 of the communication terminal 30.

  FIG. 6 is a block diagram illustrating a configuration of the metadata providing apparatus 10. The metadata providing apparatus 10 includes a control unit 110, a storage unit 120, a communication unit 130, a reception unit 140, and a clock unit 150. The control unit 110 includes an arithmetic processing device such as a CPU and a storage device such as a ROM and a RAM. The CPU of the control unit 110 controls the operation of each unit of the metadata providing apparatus 10 by executing a program stored in the ROM or the storage unit 120 using the RAM as a work area. Moreover, the control part 110 performs the information processing for assisting browsing of a user's program metadata and advertisement metadata by running a program. The communication unit 130 includes a communication interface and transmits / receives data to / from the communication terminal 30, the advertisement metadata storage device 20, and the program metadata storage device 40. The receiving unit 140 is connected to an antenna (not shown) and receives broadcast data transmitted from a plurality of broadcast stations 60, respectively. The receiving unit 140 supplies broadcast data received from an antenna (not shown) to the control unit 110. The clock unit 150 has a function of measuring the date and time, and supplies the measured date and time to the control unit 110.

  The storage unit 120 is a writable nonvolatile storage unit, for example, a hard disk. The storage unit 120 describes a program in which a procedure for performing an operation to be described later is described, a reception history table 121 in which information indicating the history of receiving advertisement broadcast data is described, and information indicating user preferences. A preference information table 122 is stored.

  FIG. 7 is a diagram illustrating an example of the preference information table 122. The preference information table 122 illustrated in FIG. 7 includes fields of “user ID”, “advertisement ID”, “view count”, and “rank”. In the “user ID” field, a user ID for identifying each user is described. In the “advertisement ID” field, an advertisement ID of advertisement broadcast data corresponding to advertisement metadata browsed in the past by the corresponding user is described. In the “view count” field, the number of times the corresponding user browsed the corresponding advertisement metadata is described. The value described in the “view count” field is the number of times the user browsed the advertisement metadata displayed on the display unit 340 of the communication terminal 30. Since the browsing count is counted by the communication terminal 30 and transmitted to the metadata providing apparatus 10 at a predetermined timing, the control unit 110 writes the count value in the preference information table 122. In the example of FIG. 7, the user with the user ID “U001” browses the advertisement metadata with the advertisement ID “C004” 105 times, and the number of times of browsing is larger than the number of times of browsing other advertisement metadata. That the user with the user ID “U001” browses the advertisement metadata with the advertisement ID “C004” most frequently means that at least the content of the advertisement metadata is greater than the content of the other advertisement metadata. It will suit your taste.

<Operation>
Next, the operation of the embodiment will be described. First, an operation in which the metadata providing apparatus 10 stores a history of receiving advertisement broadcast data will be described. FIG. 8 is a sequence chart showing an operation for storing the reception history of advertisement broadcast data. For convenience of explanation, only one of the plurality of broadcasting stations 60 is shown in FIG. 8, but each of the plurality of broadcasting stations 60 operates as shown in FIG. The control unit 110 of the metadata providing apparatus 10 performs the following operation by executing a program stored in the storage unit 120.

  The broadcast station 60 transmits broadcast data including advertisement broadcast data and program broadcast data (step S110). The receiving unit 140 of the metadata providing apparatus 10 receives program broadcast data and advertisement broadcast data transmitted from the broadcast station 60 (step S120). That is, the receiving unit 140 of the metadata providing apparatus 10 functions as a receiving unit that receives program broadcast data representing a program broadcast from a broadcast station and advertisement broadcast data representing each advertisement inserted into the program. Then, the reception unit 140 supplies the received broadcast data to the control unit 110. The control unit 110 acquires the date and time when the broadcast data is supplied from the reception unit 140 from the clock unit 150 (step S130). The control unit 110 sets the date and time acquired in step S130 as the date and time when the broadcast data is received. Note that the difference between the date and time when the broadcast station 60 transmits the broadcast data and the date and time when the metadata providing apparatus 10 receives the broadcast data transmitted from the broadcast station 60 is almost negligible, so there is no difference here. Shall.

  The controller 110 repeatedly extracts feature points of the supplied broadcast data at predetermined time intervals (step S140). As described above, this feature point is, for example, data representing the sound itself of the supplied broadcast data or data representing the characteristics of the sound. This predetermined time interval is shorter than the time interval from the date and time when reception of at least one advertisement broadcast data is started to the date and time when it is ended. The predetermined time interval may be determined in advance by the administrator of the information processing system 1 or the metadata providing apparatus 10. Next, the control part 110 transmits the feature point obtained by the process of step S140 to the advertisement metadata storage device 20 (step S150). In addition, the control unit 110 stores the date and time when the broadcast data corresponding to the feature point obtained in the process of step S140 is received and the channel number included in the broadcast data in the RAM in association with the feature point.

  The advertisement metadata storage device 20 receives the feature points transmitted from the metadata providing device 10. The advertisement metadata storage device 20 identifies the advertisement broadcast data indicated by the received feature point by comparing the feature point of the advertisement broadcast data stored in advance in the device with the received feature point (step S160). ). In the following description, the feature points extracted by the metadata providing apparatus 10 and further transmitted to the advertisement metadata storage apparatus 20 are referred to as “second feature points” and stored in advance in the advertisement metadata storage apparatus 20. The feature point of the advertisement broadcast data is referred to as “first feature point”. The advertisement metadata storage device 20 compares the first feature point and the second feature point, and the second feature point indicates the advertisement broadcast data determined that the number or ratio of the common feature points exceeds a predetermined value. The advertisement broadcast data to be shown is specified. When the advertisement broadcast data is specified, the advertisement metadata storage device 20 transmits the advertisement ID and the second feature point corresponding to the specified advertisement broadcast data to the metadata providing device 10 (step S160; YES). . On the other hand, when the advertisement metadata storage device 20 determines that there is no advertisement broadcast data in which the number or ratio of common feature points exceeds a predetermined value, the advertisement feature data storage device 20 does not indicate the advertisement broadcast data in which the second feature points are stored in advance. Is identified. This is the case, for example, where the second feature point indicates not the feature point of the advertisement broadcast data but the feature point of the program broadcast data. If the advertisement broadcast data cannot be identified, the advertisement metadata storage device 20 discards the second feature point for which the advertisement broadcast data could not be identified, and the newly received second feature point and the previously stored advertisement broadcast By comparing with the first feature point of the data, the process of specifying the advertisement broadcast data indicated by the received second feature point is repeatedly performed (step S160; NO).

  The control unit 110 of the metadata providing apparatus 10 receives the second feature point and the advertisement ID via the communication unit 130. The control unit 110 stores the information such as the channel number and date / time stored in the RAM in association with the received second feature point, and the received advertisement ID as information indicating the history of receiving the advertisement broadcast data. This is described in the reception history table 121 (step S170). In the following description, information indicating a history of receiving advertisement broadcast data is referred to as reception history information. That is, the control unit 110 receives an advertisement ID for identifying each advertisement broadcast data received by the receiving unit, a start date and time when reception of each advertisement broadcast data identified by the advertisement ID is started, and reception of each advertisement broadcast data. It functions as an advertisement date and time specifying means for specifying the completed date and time.

FIG. 9 is a diagram illustrating an example of a table in which reception history information is described. The reception history table 121 includes fields of “advertisement ID”, “start date / time”, “end date / time”, “channel”, and “block ID”.
The “advertisement ID” field is an ID for identifying advertisement broadcast data, and the advertisement ID received from the advertisement metadata storage device 20 is described therein. For example, the control unit 110 compares the advertisement IDs received continuously in time, and describes the advertisement ID only when they are different. This is based on the following reason. First, the metadata providing apparatus 10 transmits the second feature point extracted repeatedly for program broadcast data and advertisement broadcast data to the advertisement metadata storage apparatus 20. At this time, it is assumed that the metadata providing apparatus 10 extracts a plurality of second feature points from one advertisement broadcast data and transmits them to the advertisement metadata storage apparatus 20. Next, the advertisement metadata storage device 20 compares the first feature point stored in the own device with the received second feature point, and specifies the advertisement ID indicated by the second feature point. At this time, even if a plurality of second feature points are extracted from one advertisement broadcast data, the advertisement metadata storage device 20 specifies an advertisement ID for each second feature point. Then, the advertisement metadata storage device 20 transmits the advertisement ID specified for each second feature point to the metadata providing device 10. Therefore, the metadata providing apparatus 10 receives the same advertisement ID specified based on a plurality of second feature points extracted from one advertisement broadcast data. The metadata providing apparatus 10 compares the contents of the advertisement IDs received continuously in order to avoid such a situation where the same advertisement ID is described in the reception history table 121 in duplicate. It is determined whether or not the advertisement ID indicating the advertisement broadcast data is duplicated.

In the “start date and time” field, the date and time when reception of advertisement broadcast data is started is described. For example, the control unit 110 compares the contents of continuously received advertisement IDs, and only when the two are different, the date and time stored in the RAM in association with the second feature point received together with the advertisement ID is determined as the start date and time. Describe as In other words, the start date and time is described in the “start date and time” field at the same timing as the advertisement ID is described in the “advertisement ID” field. In the “end date and time” field, the date and time when reception of the advertisement broadcast data is ended is described. For example, the control unit 110 sets the latest date and time stored in the RAM in association with the second feature point received together with the same advertisement ID as the advertisement ID described in the “advertisement ID” field as the end time. Describe. In the “channel number” field, a channel number associated with the broadcast station 60 that transmitted the advertisement broadcast data is described. For example, the control unit 110 compares the contents of the advertisement IDs received continuously in time, and only when the two are different, the channel stored in the RAM in association with the second feature point received together with the advertisement ID. Describe the number. In the “block ID” field, an ID for identifying one continuous time zone in which an advertisement is broadcast, which is called a block, is described. In the example of FIG. 2, the time period from time T1 to time T4 is one block, and the time period from time T6 to time T9 is one block. For example, the controller 110 determines that the difference between the end date / time of the advertisement broadcast data received prior to the time and the start date / time of the advertisement broadcast data received subsequent to the preceding ad broadcast data is less than a threshold value. It is determined whether or not. Then, when the difference is less than the threshold, the control unit 110 determines that the advertisement broadcast data is the advertisement broadcast data received in one continuous time zone (that is, one block). Then, the control unit 110 describes the block ID for identifying this time zone in the reception history table 121. This threshold value is described in advance in a program executed by the control unit 110, or is determined in advance by the user and stored in the storage unit 120.
In the example of FIG. 9, the reception history information in the first row of the reception history table 121 includes “C001” as the advertisement ID, “T1” as the start date and time, “T2” as the end date and time, “13” as the channel number, “BU001” is included as the block ID. This indicates that the broadcast station 60 with the channel number 13 has transmitted the advertisement broadcast data with the advertisement ID “C001” between the date and time T1 and the date and time T2.

  Further, the block ID “BU001” included in the reception history information of the first to third lines of the reception history table 121 and the block ID “BU002” included in the reception history information of the fourth to sixth lines. Are different from each other. This is because the metadata providing apparatus 10 determines that the advertisement broadcast data indicated in the reception history information in the first to third lines is received in one block, and the fourth to sixth lines. This is because it is determined that the advertisement broadcast data indicated in the eye reception history information is the advertisement broadcast data received in another block. Therefore, the control unit 110 of the metadata providing apparatus 10 broadcasts the end date and time specified by the advertisement date and time specifying unit with respect to the advertisement broadcast data representing the advertisement broadcast in advance in time and the advertisement after the advertisement. If the difference between the advertisement broadcast data representing the advertisement and the start date and time specified by the advertisement date and time specifying means is less than the threshold, the broadcast date and time of the advertisement that was broadcast in advance and the advertisement that was broadcast after that It functions as a determination means for determining that the broadcast date and time belong to one continuous time zone. Then, the storage unit 120 of the metadata providing apparatus 10 determines that the advertisement ID, start date / time and end date / time of each advertisement broadcast data specified by the advertisement date / time specifying unit and the broadcast date / time of the advertisement represented by each advertisement broadcast data belong. It functions as a storage means for storing the time zone ID for identifying the time zone determined by the means in association with each other.

  The processes in steps S110 to S170 as described above are repeated each time the metadata providing apparatus 10 receives broadcast data. Therefore, reception history information indicating the advertisement broadcast data is stored in the storage unit 120 of the metadata providing apparatus 10 in a state where there is little time lag after the advertisement broadcast data is received.

Now, when the user of the communication terminal 30 wishes to view information related to the program or advertisement while viewing the program or advertisement via the receiver 50, the user of the communication terminal 30 performs a predetermined operation on the communication terminal 30, Request program metadata and advertisement metadata. The operation of the information processing system 1 in response to this request will be described.
FIG. 10 is a sequence chart showing the operation of the information processing system in response to a request for program metadata and advertisement metadata. The user performs an operation for requesting program metadata and advertisement metadata to the metadata providing apparatus 10 from the operation unit 360 of the communication terminal 30 by designating a desired channel number or program ID. Here, it is assumed that the user has designated channel number 13. The control unit 310 of the communication terminal 30 acquires the current date and time T10 from the clock unit 350 (here, the date and time T9 illustrated in FIG. 9 is a date and time earlier than the date and time T10). Then, the control unit 310 sends the terminal identification information corresponding to the user ID “U001”, the current date and time “T10”, and the program metadata and advertisement metadata corresponding to the channel number “13” to the metadata providing apparatus 10. Request (step S210).

  In response to this request, the control unit 110 of the metadata providing apparatus 10 converts the program metadata corresponding to the program broadcast data transmitted from the broadcasting station 60 of the channel number 13 during a predetermined period before the date and time T10 into the program metadata. A request is made to the storage device 40 (step S220). The predetermined period may be determined in advance by the administrator of the information processing system 1 or the metadata providing apparatus 10. In the following description, this predetermined period is referred to as a period N.

  The program metadata storage device 40 refers to the table (FIG. 4) in which the program metadata is described, and the program corresponding to the program broadcast data transmitted from the broadcast station 60 of the channel number 13 during the period N before the date and time T10. Metadata is specified (step S280). The program metadata storage device 40 transmits the specified program metadata to the metadata providing device 10 (step S290). The control unit 110 of the metadata providing apparatus 10 receives the program metadata via the communication unit 130 (step S295). Here, the control unit 110 of the metadata providing apparatus 10 generates program metadata representing the attribute of the program broadcast data received by the receiving unit and advertisement metadata representing the attribute of the advertisement broadcast data received by the receiving unit. It functions as an acquisition means for acquiring. Since the program metadata is manually created by a person who has watched the program as described above, the program metadata storage device 40 performs processing from the time when the program broadcast data is actually transmitted from the broadcast station 60. There is a gap in the time until identification. Therefore, the program metadata storage device 40 can identify program metadata corresponding to all program broadcast data transmitted from the broadcast station 60 of channel number 13 in the period N before the date T10 in the process of step S280. Is not limited. Therefore, here, it is assumed that the program metadata storage device 40 transmits only the program metadata having the program ID BA001 and the corner ID BC001 to the metadata providing device 10.

  Next, the operation of the metadata providing apparatus 10 that has received the request transmitted in the process of step S210 will be described. In response to this request, the control unit 110 of the metadata providing apparatus 10 receives the advertisement ID and block ID of the advertisement broadcast data transmitted from the broadcasting station 60 with the channel number 13 during the period N before the date and time T10. It is specified from the reception history table 121 (step S225). Here, for example, the control unit 110 is included in the reception history information from the first line to the sixth line of the reception history table 121 shown in FIG. 9 as the reception history information corresponding to the period N before the date and time T10. It is assumed that the advertisement ID and the block ID are specified. That is, the control unit 110 identifies C001 to C003 as the advertisement ID with the block ID BU001 and C001 to C002 and C004 as the advertisement ID with the block ID BU002. Subsequently, the control unit 110 requests the advertisement metadata corresponding to the advertisement ID by transmitting these identified advertisement IDs to the advertisement metadata storage device 20 (step S230).

  The advertisement metadata storage device 20 specifies advertisement metadata corresponding to the advertisement ID included in this request from the table in which the advertisement metadata shown in FIG. 3 is described (step S240). In this case, the advertisement metadata storage device 20 uses the table shown in FIG. 3 to display the first row of advertisement metadata corresponding to the advertisement ID “C001” and the second row of advertisement metadata corresponding to the advertisement ID “C002”. The advertisement metadata on the third line corresponding to the advertisement ID “C003” and the advertisement metadata on the fourth line corresponding to the advertisement ID “C004” are specified. Then, the advertisement metadata storage device 20 transmits the specified advertisement metadata to the metadata providing device 10 (step S250).

  The control unit 110 of the metadata providing apparatus 10 receives the advertisement metadata specified in response to the request via the communication unit 130 (step S260). Next, the control unit 110 identifies, for each block ID, the advertisement metadata that best matches the user's preference from the received advertisement metadata (step S270). Specifically, the control unit 110 identifies, for each block ID, the advertisement metadata having the largest number of user browsing times described in the preference information table 122 from the received advertisement metadata. Then, the control unit 110 specifies the advertisement metadata specified for each block ID as the advertisement metadata that best matches the user's preference. In this case, the control unit 110 identifies the advertisement metadata of the advertisement ID “C001” that has the highest number of browsing times among the reception history information including BU001 as the block ID as the advertisement metadata that best matches the user's preference. To do. In addition, the control unit 110 identifies the advertisement metadata of the advertisement ID “C004” having the highest number of browsing times among the reception history information of BU002 as the block ID as the advertisement metadata that best matches the user's preference. That is, the control unit 110 of the metadata providing apparatus 10 functions as a browsing tendency specifying unit that specifies a browsing tendency of a user who browses advertisements. The browsing tendency here is what kind of advertisement the user tends to browse more. In addition, the control unit 110 of the metadata providing apparatus 10 uses the browsing tendency specifying unit to identify the browsing tendency of the user from the advertisement IDs stored in the storage unit in association with each time zone ID (block ID). It functions as an advertisement ID specifying means for specifying the advertisement ID of the advertisement corresponding to each time zone ID. And the control part 110 transmits the advertisement metadata specified by the process of this step S270, and the program metadata received by step S295 to the communication terminal 30 via the communication part 130 (step S300). As described above, the control unit 110 of the metadata providing apparatus 10 acquires the advertisement metadata representing the attribute of the advertisement broadcast data of the advertisement ID specified by the advertisement ID specifying unit among the advertisement metadata acquired by the acquiring unit, and the acquisition Information for displaying the program metadata acquired by the means on the communication terminal of the user functions as a transmission means for transmitting to the communication terminal.

  When receiving the advertisement metadata and the program metadata through the communication unit 330, the control unit 310 of the communication terminal 30 stores them in the RAM. And the control part 310 displays advertisement metadata and program metadata on the display part 340 (step S310). More specifically, as shown in FIG. 11C, the control unit 310 of the communication terminal 30 responds to the program broadcast data D1 (program ID: BA001, program code ID: BC001) received in the process of step S295. According to the outline of the program metadata d21, the outline of the advertisement metadata a2 corresponding to the advertisement broadcast data A (advertisement ID: C001) specified in the process of step S270, and the advertisement broadcast data G (advertisement ID: C004) The summary of the advertisement metadata g2 is displayed on the display unit 340 as a list arranged in time series. The outline of the advertisement metadata and the outline of the program metadata here are a part of each metadata. For example, the outline of the advertisement metadata is the company name in the example of FIG. , Product name and title.

  In the display state as shown in FIG. 11C, the user performs an operation for designating an outline of desired advertisement metadata or program metadata from the operation unit 360 of the communication terminal 30, so that desired advertisement metadata or All contents of program metadata can be browsed. That is, when an outline of advertisement metadata is specified by a user operation, the control unit 310 reads all of the advertisement broadcast data from the RAM and causes the display unit 340 to display the advertisement broadcast data. In addition, when an outline of program metadata is designated by a user operation, control unit 310 reads all of the program broadcast data from RAM and causes display unit 340 to display it. As described above, when all the advertisement broadcast data is displayed or when all the program broadcast data is displayed, the control unit 310 considers that the user has viewed the advertisement metadata or the program metadata. That is, the control unit 310 does not consider that the advertisement metadata or the program metadata is simply displayed, but does not regard it as being browsed, and regards that the advertisement metadata or the program metadata is viewed when all the contents are displayed. It is.

  Then, the control unit 310 of the communication terminal 30 temporarily stores the number of times the user browses the content of the advertisement metadata or the program metadata (the number of browsing) in the RAM or the storage unit 320 of the own device, The browsing count is transmitted to the metadata providing apparatus 10 in association with the user ID or the advertisement ID at the timing (step S320). And the control part 110 of the metadata provision apparatus 10 received with respect to the browsing count described in the field of the browsing count of the record according to the received user ID and advertisement ID in the preference information table 122 of FIG. Add the number of views. As described above, the storage unit 120 of the metadata providing apparatus 10 acquires a notification indicating that the advertisement metadata transmitted by the transmission unit has been browsed by the user in the communication terminal from the communication terminal, and according to the notification, It functions as browsing count storage means for storing the advertisement browsing count and the user ID for identifying the user in association with each other.

  Here, the control unit 110 of the metadata providing apparatus 10 limits the communication metadata to the advertisement metadata specified for each block in the process of step S270 instead of all of the advertisement metadata received in the process of step S260. The reason for transmission will be described with reference to FIG.

  In the example of FIG. 11, the time axis t represents the flow of time. First, FIG. 11A shows advertisement broadcast data and program broadcast data transmitted from the broadcast station 60 in time series, and shows the same contents as FIG. Next, FIG. 11B shows a time series of the outline of the program metadata corresponding to all the program broadcast data shown in FIG. 11A and the outline of the advertisement metadata corresponding to all the advertisement broadcast data. It is a figure which shows the display content when it assumes that it was arranged in order and displayed on the communication terminal 30. FIG. FIG. 11C shows an overview of the program metadata according to the program broadcast data shown in FIG. 11A and an overview of the advertisement metadata according to the advertisement broadcast data that best matches the user's preference. It is a figure which shows the display content when the list arranged in series is displayed on the communication terminal. For example, the outline of the advertisement metadata corresponding to the advertisement broadcast data A in FIG. 11A corresponds to the outline of the advertisement metadata a2 in FIG. 11C, and the program broadcast data D1 in FIG. 11 corresponds to the outline of the program metadata d21 in FIG. 11C, and the outline of the advertisement metadata corresponding to the advertisement broadcast data G in FIG. This corresponds to the outline of the advertisement metadata g2 in (c).

  Here, the difference between the number of broadcasts of a program and the number of broadcasts of an advertisement will be described. First, the broadcast station 60 often transmits program broadcast data only once, while the number of times of transmission of advertisement broadcast data is the program broadcast data. In many cases, advertisement broadcast data is repeatedly transmitted. For example, advertisement broadcast data A and advertisement broadcast data E, advertisement broadcast data B and advertisement broadcast data F in FIG. 11A have the same advertisement ID and indicate advertisement broadcast data having the same contents. In this case, even if the user views an advertisement corresponding to the advertisement broadcast data on the receiver 50, the user is not interested in the advertisement every time the user views the advertisement. Accordingly, as shown in FIG. 11B, the user has an overview of the advertisement metadata a1 and an overview of the advertisement metadata e1, and an overview of the advertisement metadata b1 and an overview of the advertisement metadata f1, respectively. Even if displayed on the display unit 340, the user is interested in each advertisement metadata and does not intend to browse each time. Therefore, even if the metadata providing apparatus 10 transmits the advertisement metadata corresponding to all of the advertisement broadcast data transmitted from the broadcast station 60 to the communication terminal 30 possessed by the user, waste is increased.

  In addition, since the program metadata is manually created by a person who has watched the program, there is a difference between the time when the program is actually broadcast and the time until it is specified by the processing of the program metadata storage device 40. . Therefore, the metadata providing apparatus 10 cannot always transmit program metadata immediately to the communication terminal 30 owned by the user. On the other hand, since the advertisement metadata is stored in advance in the advertisement metadata storage device 20, there is a difference between the time when the advertisement is actually broadcast and the time specified by the processing of the advertisement metadata storage device 20. Smaller than the shift in program metadata. Therefore, the metadata providing apparatus 10 can immediately transmit the advertisement metadata to the communication terminal 30 owned by the user.

  In such a case, it is assumed that the user browses a program corresponding to the program broadcast data D2 with the receiver 50 and further requests program metadata corresponding to the program from the communication terminal 30. The date and time when this request is made is defined as date and time T10. However, the time taken from the broadcast of a certain program to the transmission of the program metadata to the communication terminal 30 possessed by the user is the amount of advertisement metadata transmitted to the communication terminal 30 possessed by the user after the broadcast of a certain advertisement. Is longer than the time it takes to be sent. Therefore, as in the example of FIG. 11B, the advertisement metadata e1, the advertisement metadata f1, and the advertisement metadata g1 precede the program metadata d12 corresponding to the program broadcast data D2 desired by the user, It may be displayed on the display unit 340 of the communication terminal 30. In this case, the user must check whether the outline of the desired program metadata is displayed from among the outlines of a large number of advertisement metadata, so that the user can easily view the metadata. It's hard to say the situation.

  For such a reason, as shown in FIG. 11C, the communication terminal 30 provides an overview of the program metadata and the advertisement metadata specified as the advertisement metadata that best matches the user's preference for each block ID. By displaying the summary as a list arranged in time series on the display unit 340, it is possible for the user to easily view various information.

  According to the embodiment described above, the metadata providing apparatus 10 can specify the browsing tendency when each user browses the advertisement by acquiring the advertisement metadata browsing count from the communication terminal 30. . Moreover, since the metadata providing apparatus 10 transmits the program metadata and the advertisement metadata corresponding to the browsing tendency of the user to the communication terminal 30 possessed by the user, useless advertisement metadata that is unlikely to be browsed by the user. You don't have to send Furthermore, the communication terminal 30 displays the overview of the received program metadata and the overview of the advertisement metadata that suits the user's preference on the display unit 340 in a time series, so that the user can easily browse various types of information. Can be provided. For these reasons, the user can easily browse the metadata of broadcast program broadcast data and advertisement broadcast data with interest.

<Modification>
The contents of the above-described embodiment may be modified as follows. The modifications shown below may be implemented by appropriately combining each of them as necessary.

<Modification 1>
In the embodiment, the control unit 110 of the metadata providing apparatus 10 selects the advertisement metadata having the highest number of browsing times among the reception history information including one block ID as the advertisement metadata that best matches the user's preference. It specified as data and transmitted with respect to the communication terminal 30 which a user possesses. Instead of this, the control unit 110 also sends advertisement metadata other than the advertisement metadata having the largest number of browsing times to the communication terminal 30 possessed by the user in the reception history information including a certain block ID. You may send it. In this case, the control unit 110 of the metadata providing apparatus 10 transmits information for distinguishing between the advertisement metadata having the largest number of browsing times by the user and other advertisement metadata. Then, the control unit 310 of the communication terminal 30 also uses, for example, the advertisement metadata identified as the advertisement metadata other than the advertisement metadata with the largest number of browsing by the user based on the information for distinguishing, for example, Information including a link to the advertisement metadata may be displayed on the display unit 340.

<Modification 2>
In the embodiment, the control unit 110 of the metadata providing apparatus 10 specifies advertisement metadata that matches the user's preference based on the number of browsing times described in the preference information table 122. However, the method by which the control unit 110 of the metadata providing apparatus 10 specifies advertisement metadata that matches the user's preference is not limited to this.
For example, in the process of step S320 in FIG. 10, the control unit 310 of the communication terminal 30 not only displays the advertisement metadata browsing count, but also information indicating the items of advertisement metadata browsed by the user, and advertisement metadata browsed by the user. Information indicating the genre of data may be transmitted to the metadata providing apparatus 10. This item is the type of each attribute of the advertisement, and includes, for example, the advertisement ID, company name, product name, title, performer, BGM, and genre of the advertisement metadata. In addition, the control unit 310 of the communication terminal 30 determines the advertisement metadata browsed by the user based on the information input by the operation of the user operation unit 360 and the content of the advertisement metadata received from the metadata providing apparatus 10. What is necessary is just to acquire the information which shows an item, and the information which shows the genre of the advertisement metadata which the user browsed. Then, the control unit 110 of the metadata providing apparatus 10 stores the following table in the storage unit 120 based on the received information. FIG. 12 is a diagram illustrating an example of a table in which information for specifying a preference is described.

  The second preference information table shown in FIG. 12A has fields of “user ID”, “genre”, “view count”, and “rank”. In the “user ID” field, a user ID for identifying a user is described. In the “genre” field, the genre of the advertisement metadata browsed in the past by the corresponding user is described. In the “view count” field, the number of times the corresponding user browsed the advertisement metadata of the corresponding genre is described. The value described in the “browsing count” field is a value counted by the communication terminal 30 and transmitted to the metadata providing apparatus 10 at a predetermined timing. In the record on the first line in FIG. 12A, the user with the user ID “U001” has browsed the advertisement metadata corresponding to the genre of “electric” 105 times, and the advertisement meta data corresponding to other genres. It is shown that it is more than the number of times the data was viewed. This indicates that the user is more interested in the advertisement metadata corresponding to the “food” genre than the advertisement metadata corresponding to other genres. Therefore, the storage unit 120 of the metadata providing apparatus 10 acquires a notification indicating that the advertisement metadata transmitted by the transmission unit has been viewed by the user at the communication terminal from the communication terminal, and in accordance with the notification, Function as third storage means for storing the number of browsing times, the user ID for identifying the user, and the field of the product or service to which the advertisement target represented by the advertisement broadcast data corresponding to the advertisement metadata belongs in association with each other. become.

  When the control unit of the metadata providing apparatus 10 specifies advertisement metadata that matches the user's preference based on the number of browsing times described in the preference information table 122, the control unit of the metadata providing apparatus 10 ranks in the order described in the second preference information table. A corresponding weighting may be performed. The weighting here is, for example, “1.5” as the number of browsing times described in the preference information table 122 if the ranking described in the second preference information table is “1st to less than 10th”. If it is “10th to less than 50”, the number of browsing times described in the preference information table 122 is multiplied by “1.2”, and if it is “50th to less than 100”, the preference information The number of times of browsing described in the table 122 is multiplied by “1.1”. The values and ranks to be multiplied may be set as appropriate by the user or the administrator. Thereby, the control unit 310 of the communication terminal 30 can preferentially display the advertisement metadata of the genre that is frequently viewed by the user on the display unit 340.

  In addition, the control unit 310 of the communication terminal 30 may emphasize the advertisement metadata and display it on the display unit 340 in accordance with the order described in the second preference information table. The emphasis here is, for example, if the rank described in the second preference information table is “1st or more and less than 10th”, it is displayed in “red” on the display unit 340, and “10th or more” If it is “less than 50”, it is displayed on the display unit 340 in “blue”, and if it is “other ranks”, it is displayed on the display unit 340 in “black”. About this color and order | rank, what is necessary is just to set suitably by the user or the administrator. Thereby, the control part 310 of the communication terminal 30 can emphasize and display the advertisement metadata of a genre that is frequently viewed by the user on the display part 340.

  The third preference information table shown in FIG. 12B has fields of “user ID”, “item”, “view count”, and “rank”. In the “item” field, items of advertisement metadata browsed in the past by the corresponding user are described. This item is a type of each attribute of the advertisement, and includes, for example, advertisement ID of advertisement metadata, company name, product name, title, performer, BGM, genre, and the like. In the “view count” field, the number of times the corresponding user has browsed the corresponding item of the advertisement metadata is described. The value described in the “browsing count” field is a value counted by the communication terminal 30 and transmitted to the metadata providing apparatus 10 at a predetermined timing. In the record on the first line in FIG. 12B, the user with the user ID “U001” has viewed the performer item of the advertisement metadata 105 times, and compared with other items of the advertisement metadata. It is shown that the number of browsing is the most. This indicates that the user with the user ID “U001” is more interested in the information described in the item of the performer of the advertisement metadata than the information described in the other items of the advertisement metadata. Yes. Accordingly, the storage unit 120 of the metadata providing apparatus 10 provides a notification indicating that a certain attribute has been browsed by the user among a plurality of attributes of the advertisement broadcast data included in the advertisement metadata transmitted by the transmission unit. , Acquired from the communication terminal, and functions as fourth storage means for storing each advertisement browsing count, a user ID for identifying the user, and the attribute browsing count in association with each other in accordance with the notification.

  The control unit 110 of the metadata providing apparatus 10 may perform weighting according to the order described in the third preference information table even when browsing the advertisement metadata. For example, when the user's browsing count described in the third preference information table satisfies a condition that means that the browsing frequency is high, the control unit 110 of the metadata providing apparatus 10 sets the attribute as the other attribute. May transmit information to be displayed on the user's communication terminal in a different display mode to the communication terminal. More specifically, the control unit 110 of the metadata providing apparatus 10 emphasizes an item (attribute) of advertisement metadata that is frequently viewed by the user according to the order described in the third preference information table. Information to be displayed on the display unit 340 is transmitted to the communication terminal 30. Thereby, even when the advertisement metadata is browsed by the user, the control unit 310 of the communication terminal 30 can emphasize and display the advertisement metadata item that is frequently viewed by the user on the display unit 340. it can.

<Modification 3>
In the embodiment, since the metadata providing apparatus 10 stores the advertisement metadata in the advertisement metadata storage apparatus 20 in advance, the metadata providing apparatus 10 is specified by the process of the advertisement metadata storage apparatus 20 from the time when the advertisement is actually broadcast. The deviation that occurs in the time until the program is assumed to be smaller than the deviation of the program metadata. However, the metadata providing apparatus 10 is not always able to immediately specify advertisement metadata according to the user's preference.
If the process of specifying the advertisement metadata that matches the user's preference (FIG. 10: step S270) takes time, the control unit 110 of the metadata providing apparatus 10 does not wait for the completion of this process, You may transmit all the advertisement metadata received by the process of S250 with respect to the communication terminal 30 (step S300). In this case, the control unit 310 of the communication terminal 30 displays all the received advertisement metadata on the display unit 340 (step S310). Subsequently, the control unit 110 of the metadata providing apparatus 10 transmits the specified advertisement metadata to the communication terminal 30 as soon as the process of step S270 is completed. Here, the control unit 310 of the communication terminal 30 causes the display unit 340 to display only the advertisement metadata that matches the user's preference, as in the above-described embodiment. In this way, the metadata providing apparatus 10 can transmit the advertisement metadata to the user at least quickly.

<Modification 4>
The control unit 310 of the communication terminal 30 temporarily stores the number of times the user browses the content of the advertisement metadata or the program metadata (the number of browsing) in the RAM or the storage unit 320 of the own device, and at a predetermined timing. This browsing count is transmitted to the metadata providing apparatus 10 in association with the user ID, the advertisement ID, and the like. On the other hand, the control unit 310 of the communication terminal 30 displays not only the number of times the user browses the advertisement metadata but also the number of times that the summary of the advertisement metadata transmitted from the metadata providing apparatus 10 is displayed on the display unit (number of display times). May be temporarily stored in the RAM or the storage unit 320 of the own device, and the display count and the browse count may be associated with the user ID, the advertisement ID, or the like at a predetermined timing and transmitted to the metadata providing apparatus 10. . The control unit 110 of the metadata providing apparatus 10 stores the following table in the storage unit 120 based on the received information. FIG. 13 is a diagram illustrating an example of a table in which information indicating a browsing tendency is described.

  The table in which information indicating the browsing tendency shown in FIG. 13 is described includes fields of “user ID”, “display count”, and “view count”. In the “user ID” field, a user ID for identifying a user is described. In the “display count” field, the range of the number of times the summary of the advertisement metadata transmitted from the metadata providing apparatus 10 is displayed on the display unit is described. In the “view count” field, the user designates an outline of the advertisement metadata displayed on the display section as many times as described in the “display count” field from the operation section 360 of the communication terminal 30. Describes the number of times the content of the advertisement metadata has been browsed. In other words, in the example of FIG. 13, the user with the user ID “U001” views the advertisement metadata with the first display count of 105 times, and the advertisement metadata with the display count of the second and subsequent times is less than the fifth. It is shown that the number of times of browsing is 43, and the number of times of viewing advertisement metadata with the number of display times from the fifth time to less than the tenth time is 13 times. Therefore, this user tends to browse the advertisement metadata displayed for the first time (for the first time). The control unit of the metadata providing apparatus 10 may emphasize the advertisement metadata and display it on the display unit 340 in accordance with the display count. Accordingly, the storage unit 120 of the metadata providing apparatus 10 includes the first storage unit that stores the number of times the transmission unit has transmitted the advertisement metadata to the communication terminal, and the advertisement metadata transmitted by the transmission unit is the user at the communication terminal. A notification indicating that the advertisement has been browsed is acquired from the communication terminal, and functions as a second storage unit that stores the number of times each advertisement is browsed and the user ID for identifying the user in association with each other according to the notification.

<Modification 5>
In the embodiment, the control unit 110 of the metadata providing apparatus 10 selects the advertisement metadata having the highest number of browsing times among the reception history information including one block ID as the advertisement metadata that best matches the user's preference. The data was specified and transmitted to the communication terminal owned by the user. Instead of this, the control unit 110 of the metadata providing apparatus 10 selects the advertisement metadata having the largest number of browsing times among the reception history information corresponding to the plurality of block IDs as the advertising metadata that best matches the user's preference. The data may be specified and transmitted to the communication terminal 30 owned by the user. The number of block IDs may be set as appropriate by the user or administrator.
In addition, the control unit 110 of the metadata providing apparatus 10 sets a predetermined number of advertisement metadata according to the user's preference from the reception history information including a certain block ID in descending order of the user's browsing frequency. It may be specified as matching advertisement metadata and transmitted to a communication terminal owned by the user. The predetermined number of advertisement metadata may be set as appropriate by a user or an administrator.
In addition, the control unit 110 of the metadata providing apparatus 10 identifies advertisement metadata having a user's browsing count equal to or greater than a threshold as advertisement metadata satisfying the user's preference from reception history information including a certain block ID. However, it may be transmitted to a communication terminal owned by the user. The threshold for the number of browsing times may be set as appropriate by the user or the administrator.

<Modification 6>
In the embodiment, the advertisement metadata and the program metadata to be transmitted to the communication terminal 30 are specified by the three devices, that is, the metadata providing device 10, the advertisement metadata storage device 20, and the program metadata storage device 40.
