In accordance with the process of generating link information and the content playback instruction, the CM associated with the content for which playback has been instructed is identified from at least one of the first link information and the second link information. And a control unit for executing the process of reproducing the specified CM.

  As described above, according to the mobile terminal of the present invention, the user can efficiently view the CM.

The best mode for carrying out the present invention will be described below with reference to the drawings.
<First embodiment>
FIG. 1 shows a distribution system 1 according to the first embodiment of the present invention.

  As shown in the figure, the distribution system 1 includes a distribution server 10 that distributes content and CM, and a mobile terminal 20 that receives distribution of content and CM from the distribution server 10 via a network 900 and an access point 800. It is configured.

  The network 900 is a public communication network including a telephone / mobile phone network and the Internet.

  AP (access point) 800 relays the connection between mobile terminal 20 and network 900, and mobile terminal 20 is connected to network 900 by transmitting and receiving radio waves to and from AP 800.

  The distribution server 10 accumulates content data and CM data and distributes them to the mobile terminal 20.

  The mobile terminal 20 is, for example, a mobile phone, a portable player, or a head-mounted display, and the form thereof is not limited as long as it is a terminal that can reproduce images and sounds.

  First, the distribution server 10 will be described in detail.

  The distribution server 10 includes a control unit 110, a storage unit 120, and an I / F unit 130.

  The storage unit 120 stores a content database 121, a CM database 122, and customer information 123.

  In the content database 121, content related information including content data distributed to a client (here, the user of the mobile terminal 20) and content metadata including information related to the content data is stored in advance. The content data is, for example, all digital data such as music, video, images, and documents.

  Each content data is preliminarily provided with metadata for managing them. The metadata is composed of a plurality of pieces of information describing the content. For example, the content ID, genre, title, creation location, and predicted audience attribute (for example, age, residential area, gender, and preference) Etc.) is stored.

  The CM database 122 stores in advance CM-related information having CM data related to so-called CM (commercial) for distributing advertisement information and CM metadata having information related to the CM data. The CM data in the present invention is data for the purpose of advertising to clients, and the format is not particularly limited.

  Note that, for example, metadata shown in FIG. 2 for managing the CM data stored in the CM database 122 is given in advance. As shown in the figure, the metadata added to the CM data includes, for example, the CM ID, title, creation date, CM, the recommended region and time zone for viewing, and the target consumer group. Are stored, for example, information on the ID (eg, information on age, residential area, gender, preference, etc.) and the ID of the content to be linked.

  Here, each CM data is associated with the content data by the data distribution unit 112 described later, and distributed to the user. Therefore, at the time of such association, the data distribution unit 112 describes the ID of the content data as the link destination in the metadata attached to the CM data distributed to the client.

  Note that the content data to be linked can be used for the process of determining the distribution timing of the CM data, the playback timing in the mobile terminal 20, and the like.

  For example, when the content distribution unit 112 described later distributes content, CM data with the content as a link destination is added to the content data and transmitted to the mobile terminal 20. Further, the data reproduction unit 213 of the mobile terminal 20 can be configured to reproduce a CM linked to the content at a predetermined timing when the content is reproduced.

  One content may be designated as a link destination by a plurality of CMs.

  Further, when there are a plurality of contents to be distributed, a CM having the same contents may be designated as a link destination.

  The customer information 123 is information generated for each client by the customer management unit 111 described later. The customer information 123 can be composed of, for example, a client ID for identifying the mobile terminal 20 and the client, and attribute information obtained by converting personal information related to the client's age, gender, address, preference, and the like into data. (Not shown).

  The control unit 110 includes a customer management unit 111 that generates customer information 123, and a data distribution unit 112 that distributes content and CM to clients. Hereinafter, when content and CM are transmitted from the distribution server 10 to the mobile terminal 20, it is assumed that content-related information and CM-related information with metadata are distributed.

  The customer management unit 111 receives information from a client in advance and generates customer information 123 for each client.

  Specifically, the customer management unit 111 receives in advance attribute information such as age, sex, address, and preference for each client via a web page or the like. Such attribute information is stored as customer information 123 in association with a client ID for identifying the client and the mobile terminal 20.

  The data distribution unit 112 distributes content and CM to the mobile terminal 20.

  Distribution of content and CM is executed in response to a distribution request from the mobile terminal 20. The distribution request is, for example, a list of contents that can be distributed to the mobile terminal 20 by the data distribution unit 112 in advance, and the user can request distribution of desired contents based on the list.

  Specifically, when receiving a content distribution request from the mobile terminal 20, the data distribution unit 112 associates CM data with the content requested to be distributed and distributes it to the client.

  Regarding the association processing of CM data, the method and the number are not particularly limited. An example is shown below.

  For example, the data distribution unit 112 selects, from the CM database 122, a CM that matches the content of the content requested to be distributed and client attribute information stored in advance as the customer information 123.

  Specifically, first, the data distribution unit 112 compares the content of the content requested to be distributed with the content of the CM, and calculates the fitness.

  The degree of fitness is obtained by, for example, placing a weighting factor in advance on the metadata items assigned to the CM, comparing the CM metadata and the content metadata, and calculating the sum of the weighting factors of the matching items. Can be estimated.

  The data distribution unit 112 determines that the higher the sum is, the higher the degree of matching between the content and the CM is, and extracts a predetermined number of CM data in descending order of the degree of matching.

  Similarly, the data distribution unit 112 calculates the degree of matching between the extracted CM data and the client.

  Specifically, the matching degree can be estimated by comparing the attribute information of the client with the metadata of the CM and calculating the sum of the weighting factors of the matching items. The data distribution unit 112 further extracts a predetermined number of CMs in descending order of fitness.

  Then, the data distribution unit 112 distributes the CM extracted in this way to the mobile terminal 20 in association with the content requested to be distributed. At this time, the data distribution unit 112 stores the ID of the link destination content, that is, the ID of the content requested for distribution, in the metadata of the CM data to be distributed, and transmits it to the mobile terminal 20. .

  Further, when there are a plurality of contents to be distributed, a plurality of contents IDs to be linked may be stored in the metadata of the CM data to be distributed and transmitted.

  The distribution of the CM data may be performed simultaneously with the content requested to be distributed, or may be performed at different timings.

  The I / F unit 130 provides an interface between the network 900 and each functional unit, and connects the distribution server 10 to the mobile terminal 20 via the network 900 so that data can be transmitted and received.

  Next, the mobile terminal 20 will be described in detail.

  The mobile terminal 20 includes a control unit 210, a storage unit 220, an I / F unit 230, a GPS reception unit 240, an audio output unit 250, a display unit 260, and an input unit 270.

  The control unit 210 includes a data management unit 211, an information acquisition unit 212, and a data reproduction unit 213.

  The data management unit 211 receives an instruction operation from the user via the input unit 270 and outputs a content distribution request to the distribution server 10. Then, distribution of content and CM is received from the distribution server 10.

  Specifically, when receiving an instruction to distribute desired content from the user via the input unit 270, the data management unit 211 transmits a content distribution request including a content ID designating the distribution content to the distribution server 10. When the content and CM supplied from the distribution server 10 are received, these are stored in the data storage area 221 of the storage unit 220.

  Furthermore, the data management unit 211 registers the information regarding the content and CM that received the distribution in the link table as shown in FIG.

  The link table stored in the link table storage area 222 is a table for managing the association (link information) between content and CM. The link table includes a content ID storage area 222a in which the content ID of the content stored in the data storage area 221 is stored, and a CMID storage area 222b in which the ID of a CM linked to the content is stored.

  First, the data management unit 211 registers content and CM link information newly supplied from the distribution server 10 in the link table.

  Specifically, the data management unit 211 stores the content ID included in the metadata of the distribution content in the content ID storage area 222a. Further, the data management unit 211 refers to the link destination information of the metadata of the distribution CM and specifies the content ID to be linked. Then, the record for storing the content ID is specified from the link table, and the ID of the distribution CM is stored in the CMID storage area 222b of the record.

  The processing when the data management unit 211 receives content and CM distribution from the distribution server 10 has been described above.

  Next, a process in which the data management unit 211 increases / decreases links between contents and CMs based on the state of the mobile terminal 20 will be described.

  First, the data management unit 211 determines the status of the mobile terminal.

  Specifically, the data management unit 211 acquires the position time information output from the information acquisition unit 212 at regular time intervals.

  The information acquisition unit 212 acquires a GPS signal that specifies a position and a time from the GPS reception unit 240 at predetermined intervals. Then, the position and time are specified based on the GPS signal, position time information is generated and supplied to the data management unit 211.

  Note that the location can be specified in detail by providing the storage unit 220 with map information (not shown) for determining the country and region from the latitude and longitude.

  When the data management unit 211 receives the location time information from the information acquisition unit 212, the link information of the CMs that are not included in the region and time zone in which the location and time of the mobile terminal 20 are recommended to be viewed for a certain period of time. Is deleted.

  Specifically, the data management unit 211 refers to the metadata of each CM, and determines the CMID of the CM data that is not included in the recommended region and the recommended time zone in which the location and time of the mobile terminal 20 are stored in the metadata. Identify. Then, the extracted CMID is deleted from the CMID storage area 222b of the link table. However, the data management unit does not delete the CMID stored in the record constructed by the distribution server 10, that is, the record indicating the link with the content stored in the CM metadata as the link destination information. Keep the default link built by.

  Then, a specific condition (region or time) may be set in advance in the CM metadata on the distribution server side, and when the terminal satisfies the above condition, the default link constructed by the distribution server 10 may be restored.

  Moreover, even if the CM provider sets a link information fixed flag in advance in the CM metadata on the distribution server side and the flag is valid, the default link constructed by the distribution server 10 can be maintained regardless of the status of the terminal. good.

  Next, the data management unit 211 extracts CM data included in a recommended region and a recommended time zone in which the position and time of the mobile terminal 20 are recommended for viewing stored in the metadata.

  Specifically, the data management unit 211 includes the location of the mobile terminal 20 in the recommended area stored in the metadata of each accumulated CM data, and includes the acquired time in the recommended time zone. Select CM data.

  Note that CM data in which either one of the position and the time is included in the recommended region and the time zone may be extracted. In addition, the conditions for selecting a CM recommended for viewing are not limited to the region and time zone, and may be based on conditions such as season, weather, temperature, and the like.

  Next, the data management unit 211 searches for the content to be a new link destination for each selected CM.

  Specifically, the data management unit 211 compares the metadata of each selected CM with the metadata of each accumulated content, calculates the sum of the weighting factors of the matching items, and Detect high content and CM combinations.

  Then, the data management unit 211 determines whether or not a combination of content and CM having a high fitness is registered in the link table. When the combination is not registered in the link table, the data management unit 211 adds a suitable CMID to the CMID storage area 222b of the record including the content ID to be linked and registers it as new link information.

  Note that the content to be newly linked is not limited to content having a high matching degree with the CM. For example, it is also possible to identify content with a high reproduction frequency from the most recently distributed content or the reproduction history as shown in FIG.

  Here, the link construction is described as being started when the information acquisition unit 212 receives a GPS signal at predetermined time intervals and transmits the position time information to the data management unit 211. However, the condition for starting the process is not limited to this, and when the information acquisition unit 212 determines that the position of the mobile terminal 20 has moved, it may be configured to start by outputting position time information. it can.

  When receiving a content playback instruction from the user via the input unit 270, the data playback unit 213 plays back the content data and CM data.

  Note that the CM reproduction is executed at a predetermined timing along with the content reproduction. For example, before content playback, when the content playback time reaches a predetermined length, when the chapter ends, when the content stops.

  Further, the data playback unit 213 generates a playback history of content and CM data as shown in FIG. 4 and stores it in the playback history storage area 223.

  The reproduction history is a history of content and CM reproduction processing executed according to a user's instruction. The content / CMID storage area 223a for storing the content to be controlled and the CM ID, the date and time when the control is completed, Storage area 223b at the time of update.

  The GPS receiver 240 receives a signal from a GPS (Global Positioning System) satellite.

  The I / F unit 230 provides an interface (for example, USB) between the access point 800 and each functional unit, and connects the mobile terminal 20 to other devices so as to be able to transmit and receive data.

  The input unit 270 includes an operation switch, for example, and accepts an instruction operation from a user. The operation instruction is, for example, processing such as selection, playback, and stop of each content and CM.

  The display unit 260 is a display such as an LCD, for example, and displays an image based on the image signal supplied from the data reproduction unit 213.

  The audio output unit 250 converts the audio signal supplied from the data reproduction unit 213 into audio and outputs the audio.

  Each of these devices can be configured by a computer 810 as shown in FIG. 8, for example.

  The computer 810 includes an auxiliary memory 803 such as a hard disk, a memory 802, a CPU (Central Processing Unit) 801, a communication device such as a NIC (Network Interface Card) 804, and a bus 805 for connecting them. Each control unit can be realized by reading a predetermined program stored in the auxiliary memory 803 into the memory 802 and executing it by the CPU 801.

  Next, processing when the data management unit 211 of the mobile terminal 20 acquires position time information indicating the position and time from the information acquisition unit 212 will be described with reference to FIG. FIG. 5 is a flowchart showing a flow of processing executed when the data management unit 211 acquires location time information from the information acquisition unit 212.

  The data management unit 211 determines whether or not location time information related to the location and time of the mobile terminal 20 has been acquired (S11).

  Next, when the data management unit 211 receives the location time information from the information acquisition unit 212, the location and time of the mobile terminal 20 are links of CMs that are not included in the region and time zone recommended for viewing for a certain period of time. Information is deleted (S12).

  Specifically, the data management unit 211 refers to the metadata of the CM, and the CMID of the CM data not included in the recommended region and the recommended time zone stored in the metadata is the location and time of the mobile terminal 20. Records stored in the CMID storage area 222b are extracted from the link table. Then, among the extracted records, the content other than the content specified by the link destination information of the metadata of each CM deletes the CMID stored in the corresponding content ID storage area 222a from the CMID storage area 222b. .

  Then, the data management unit 211 selects CM data in which the location and time of the mobile terminal 20 include a recommended area and a recommended time zone that are predetermined for each CM (S13).

  Next, the data management unit 211 searches for content to be a new link destination for each CM selected in step 13 (S14).

  Specifically, the data management unit 211 collates the metadata of each CM selected in Step 13 with the metadata of each content to be accumulated, and determines the content having a high fitness for each CM data as a predetermined value. To identify the number of.

  Further, the data management unit 211 determines whether or not the combination of the content and CM specified in step 14 is registered in the link table (S15). When the combination is not registered in the link table (NO), the data management unit 211 adds a CMID that matches the CMID storage area 222b of the content record to be linked and registers new link information (S16). ). If the combination already exists in the link table (YES), the data management unit 211 ends the process.

  The processing executed when the mobile terminal 20 receives distribution of content and CM has been described above.

  According to the configuration as described above, since the CM that matches the situation of the mobile terminal 20 is always linked to the related content, the user can be effectively viewed.

  First, the data reproducing unit 313 will be described.

  The data reproducing unit 313 executes the same processing as the data reproducing unit 213 according to the first embodiment, and records the content and CM reproduction history as shown in FIG.

  Furthermore, when recording the CM playback history, the data playback unit 313 according to the present embodiment calculates the CM playback count from the playback history. If there is CM data that has been played a predetermined number of times or more, a deletion request including the CM ID is output to the data management unit 311.

  When receiving the deletion request from the data reproduction unit 313, the data management unit 311 deletes all CM IDs included in the deletion request from the CMID storage area 222b of the link table.

  In addition, when the data management unit 311 according to the present embodiment receives provision of location time information from the information acquisition unit 212 (FIG. 5, Step 11), first, in the accumulated CM data, the CMID storage area 222b is stored. It is determined whether or not there is an ID that is not stored, and CM data without link information is deleted. Only CM data without link information for a certain period of time may be deleted. Then, it progresses to step 12 and performs the process similar to 1st embodiment.

  With the configuration as described above, the distribution system 2 according to the present embodiment automatically deletes CM data that has been played a predetermined number of times or more, so that CMs that the user has already watched are not played back repeatedly. Efficient viewing is possible.

  Further, it is possible to prevent the storage of limited mobile terminals due to CM data.

  Note that the condition for outputting a CM data deletion request by the data reproducing unit 313 is not limited to the number of reproductions described above. For example, the reception date and time of CM data may be registered in the storage unit in advance, and a deletion request may be output for CM data whose elapsed time after downloading has become a predetermined value or more. Further, conditions such as the number of days elapsed from the creation date of the CM data can be further combined.

<Third embodiment>
Next, the distribution system 3 according to the third embodiment will be described below with reference to FIG. FIG. 7 is a block diagram showing a functional configuration of the distribution system 3 according to the third embodiment.
explain.

  The distribution system 3 according to the third embodiment includes a distribution server 10 and a mobile terminal 40. Hereinafter, a different part is demonstrated compared with the delivery system 1 concerning 1st embodiment.

  In the present embodiment, the mobile terminal 40 deletes the link between the content and CM that the user has instructed to delete.

  Since the distribution server 10 has substantially the same configuration as that of the first embodiment, detailed description thereof is omitted here.

  The control unit 410 of the mobile terminal 40 includes a data management unit 411, an information acquisition unit 212, and a data reproduction unit 213.

  In addition to the same processing as in the first embodiment, the control unit 410 executes processing for deleting the link between the content and the CM in response to a content data deletion instruction from the user.

  When receiving a content deletion instruction from the user, the data management unit 411 deletes the content data. Then, a record including the deleted content ID is specified in the content ID storage area 222a from the link table, and the record is also deleted.

  Similarly to the data management unit 311 according to the second embodiment, when receiving the location time information from the information acquisition unit 212, the data management unit 411 stores the CMID storage area 222b in the accumulated CM data. CM data in which no ID is stored is deleted.

  With the above configuration, the distribution system 3 according to the present embodiment can automatically delete link information between the deleted content and the CM. Accordingly, since the CM data for which only the content for which the deletion instruction is given is linked is also deleted, it is possible to prevent the CM from being stored such that there is no link information and the reproduction is not performed.

  Further, the present invention is not limited to the embodiment as described above. The above embodiment can be variously modified within the scope of the technical idea of the present invention.
