<First embodiment>
FIG. 1 is a block diagram showing the configuration of a broadcasting system 1 according to a first embodiment of the present invention. The broadcasting system 1 is a system that distributes television programs in parallel (simultaneously) by broadcasting (broadcast waves) and a communication network. Note that in the following description of this embodiment, distribution via a communication network may be referred to as net distribution.

Broadcasting system 1 roughly includes an advertisement distribution device 10, a master system 20, a commercial broadcasting system 30, a bank system 31, a CDN (Content Delivery Network) 40, an advertising material storage device 41, and a viewer terminal device 42. Among the above-mentioned components, the master system 20, commercial broadcasting system 30, and bank system 31 are systems within the broadcasting station. The advertisement distribution device 10 and the advertisement material storage device 41 may be devices outside the broadcasting station, and may be devices configured by cloud computing, for example.

The commercial broadcasting system 30 is a core business system provided at a commercial broadcasting station (commercial broadcasting station), and is a system that centrally manages programs, commercials (also referred to as advertisements), etc. broadcast by the commercial broadcasting station. The bank system 31 includes a CM bank 310 and a program bank 311. The CM bank 310 and the program bank 311 are facilities that store materials (video/audio data) for commercials and programs so that the commercials and programs can be broadcast according to a schedule.

The master system 20 includes a broadcast signal generation device 21 and a program distribution signal generation device 22. The broadcast signal generation device 21 generates a broadcast signal using data stored in the CM bank 310 and the program bank 311, and distributes the broadcast signal under the control of the commercial broadcasting system 30.

The commercial broadcasting system 30, the bank system 31, and the broadcast signal generation device 21 described above are existing equipment at the broadcasting station, so a detailed explanation thereof will be omitted in this embodiment.

The program distribution signal generation device 22 is a device that generates a television program to be broadcast by encoding a communication signal for distribution over a communication network (net distribution). In this embodiment, the SCTE (Society of Cable and Telecommunications Engineers)-35 signal, which is well-known as a broadcast standard, is used as the communication signal. The program distribution signal generation device 22 includes an extraction section 220 and an addition section 221. The extraction section 220 and the addition section 221 are examples of an extraction means and an addition means, respectively.

The extraction unit 220 extracts, from the broadcast signal generated by the broadcast signal generation device 21, CM trigger information indicating the timing at which a CM is inserted in a program, and an event ID (Identification) that can identify the program (also referred to as an event). Extract.

The broadcast signal (also called TS (Transport Stream) in general digital broadcasting) generated by the broadcast signal generation device 21 includes information called an SDT (Service Description Table) and an EIT (Event Information Table). The SDT is a table in which a list of all services included in a certain TS is described. The EIT is a table containing event IDs, and the position in the TS is specified by the SDT. Furthermore, the broadcast signal includes CM trigger information in an ANC (Ancillary) area indicated by the digital broadcast standard. Therefore, the extraction unit 220 can extract the CM trigger information from the ANC area in the broadcast signal, and also extract the event ID by referring to the SDT and EIT.

The addition unit 221 adds (incorporates) the CM trigger information and event ID extracted by the extraction unit 220 to the SCTE-35 signal generated by the program distribution signal generation device 22 in a state where they are associated with each other.

FIG. 2 is a diagram illustrating an SCTE-35 signal to which CM trigger information and event ID are added by the addition unit 221 according to the present embodiment. In the example shown in FIG. 2, the event IDs for CM-A, CM-B, and CM-C are all "00000001." The adding unit 221 associates the CM trigger information and event ID with respect to each of CM-A, CM-B, and CM-C, and adds the CM trigger information and event ID to the SCTE-35 signal. The adding unit 221 may add the CM trigger information and the 10-digit CM code to, for example, the Program ID included in the SCTE-35 signal.

The adding unit 221 sends the SCTE-35 signal to which the CM trigger information and event ID are added to the advertisement distribution device 10 shown in FIG.

The advertisement distribution device 10 is a device that uses SCTE-35 signals received from the program distribution signal generation device 22 to control the distribution of CMs in programs distributed by the CDN 40 (communication network). The advertisement distribution device 10 includes a packager 11, an SSAI (Server Side Ad Insertion) server 12, and an AD server 13. The packager 11, the SSAI server 12, and the AD server 13 may be configured as individual devices, or may be configured as individual functions of one device.

The packager 11 includes a receiving section 110.

The receiving unit 110 receives the SCTE-35 signal to which CM trigger information and event ID (also referred to as program identification information) are added, and transmits the CM trigger information and event ID included in the SCTE-35 signal via the SSAI server 12. and outputs it to the AD server 13. However, it is assumed that the receiving unit 110 is provided with information indicating in which part of the SCTE-35 signal the CM trigger information and event ID are included.

The SSAI server 12 includes an attribute acquisition section 120 and a replacement section 121.

The attribute acquisition unit 120 receives (acquires) information that can specify the attributes of the user (viewer) of the viewer terminal device 42 from the viewer terminal device 42 via a communication network (not shown). The viewer terminal device 42 is an information processing device, such as a personal computer or a smartphone, that outputs (displays) video and audio of a program distributed by SCTE-35 signals. The viewer's attributes include, for example, the viewer's gender and age. The attribute acquisition unit 120 receives, for example, a viewer ID (Identification) that can identify the viewer, as information that can identify the viewer's attributes. The viewer ID is input by the viewer using the viewer terminal device 42, for example, when the viewer uses a service for viewing a program distributed using an SCTE-35 signal.

Upon receiving the viewer's ID, the attribute acquisition unit 120 acquires information regarding the viewer's attributes from, for example, a device (not shown) that manages the viewer's ID in association with the viewer's attributes. It is possible to identify the attributes of the viewer. Alternatively, the attribute acquisition unit 120 may directly receive information regarding the attributes of the viewer from the viewer terminal device 42. The attribute acquisition unit 120 outputs information indicating the obtained attributes of the viewer to the AD server 13. The operation of the replacement unit 121 in the SSAI server 12 will be described later.

The AD server 13 includes a determining section 130 and a program information acquiring section 132. The determining unit 130 and the program information acquiring unit 132 are examples of determining means and program information acquiring means, respectively.

The program information acquisition unit 132 acquires program information 133 from a broadcast station, for example, via a dedicated communication network that can communicate with the broadcast station's system. For example, if the dedicated communication network is not constructed and the program information 133 cannot be acquired via the communication network, the program information acquisition unit 132 may acquire the program information 133 included in the broadcast waves. good. The program information 133 included in the broadcast waves is well known as, for example, EPG (Electronic Program Guide).

FIG. 3 is a diagram illustrating the contents of the program information 133 according to this embodiment. The program information 133 is, for example, information representing the content of the program that associates, for each program, the following items: event ID, program name, program type (genre), program performer, and program sponsor. . According to the program information 133 illustrated in FIG. 3, for example, regarding a program whose event ID is "00000001," the program name is "News Special Program X," the program type is "Report," and the performers are " Caster A” etc., and the sponsor is “Company E” etc. Note that the program information 133 may include items other than the items illustrated in FIG. 3.

The program information acquisition unit 132 stores the acquired program information 133 in, for example, a memory included in the AD server 13 or a nonvolatile storage device such as a magnetic disk.

The determining unit 130 shown in FIG. 1 compares the event ID received by the receiving unit 110 with the program information 133 to determine the content of the program indicated by the event ID (in the example of FIG. 3, the program name and the type of program). , program performers, and program sponsors). The determining unit 130 generates information (also referred to as advertisement identification information) that allows identification of a CM in a program to be distributed over the internet based on the content of the acquired program, the viewer attributes acquired by the attribute acquisition unit 120, and the criteria 131. Determine.

FIG. 4 is a diagram illustrating the contents of the standard 131 according to this embodiment. It is assumed that the reference 131 is stored, for example, in a memory included in the AD server 13 or a nonvolatile storage device such as a magnetic disk.

As illustrated in FIG. 4, the standard 131 includes, for example, a CM management table 134 by program genre, a CM management table 135 by performer, and an advertising material location management table 136.

The program genre-specific CM management table 134 is a table (information) that defines CM identification codes of CMs in programs distributed over the Internet for each program type indicated by the event ID. According to the program genre-specific CM management table 134 illustrated in FIG. 4, when the program type is "cooking", the determining unit 130 selects a CM for the program to be distributed over the Internet with a CM identification code of "1234-000001". etc. will be decided as a commercial. Here, a CM with a CM identification code such as "1234-000001" is a CM for a product related to cooking, such as a CM for ingredients or cooking utensils. Similarly, a CM with a CM identification code such as "2345-000001" is a CM for a product related to sports (baseball), for example, a CM for baseball equipment.

The performer-based CM management table 135 is a table (information) that defines, for each performer of the program indicated by the event ID, the CM identification code of the CM in the program distributed over the internet. According to the performer-specific CM management table 135 illustrated in FIG. 4, when the performer of a program is "Talent B", the determining unit 130 selects a CM for the program to be distributed over the Internet with a CM identification code of "3456- 000001" or the like. Here, a CM whose CM identification code is "3456-000001" or the like is a CM in which Talent B appears. Similarly, a CM with a CM identification code such as "4567-000001" is a CM in which singer C appears.

The determining unit 130 may determine the CM identification code by combining the CM management table 134 by program genre and the CM management table 135 by performer. That is, the determining unit 130 may determine the CM identification code based on both the type of program and the performer.

The program genre-specific CM management table 134 and the performer-specific CM management table 135 illustrated in FIG. 4 may further include viewer attributes. For example, the CM management table 135 by performer indicates the CM identification code of a commercial for men's products in which Talent B appears when the viewer is a man, and when the viewer is a woman, The CM identification code of the CM for women's products in which it appears may also be shown.

Standard 131 also excludes the case where the sponsor of a program with a certain event ID indicated by program information 133 and the advertiser of a CM on the online distribution side of the program are different advertisers belonging to the same industry. It may also include information indicating. In this case, the criterion 131 is, for example, for each sponsor of the program indicated by the event ID, the CM identification code of a CM of a different advertiser belonging to the same industry as the sponsor is to be excluded from the commercials of the program on the Internet distribution side. It can be expressed as

Additionally, in Standard 131, there are cases where the CM identification information of a CM distributed online is not set for the content of the program indicated by the event ID, or for the combination of the content of the program indicated by the event ID and the viewer's attributes. You can. In this case, the determining unit 130 may use, for example, a different standard from the standard 131 to determine, on the internet distribution side, to distribute a CM that is unrelated to the content of the program indicated by the event ID. An unrelated CM is, for example, a CM included in a dedicated spot contract frame on the internet distribution side.

The advertising material location management table 136 is a table (information) representing the location (address) of the advertising material 410, which is the video/audio data of the CM on the internet distribution side, specified by the CM identification code. Advertising material 410 is stored in advertising material storage device 41 connected to CDN 40, as shown in FIG. The advertising material storage device 41 is, for example, a nonvolatile storage device such as a magnetic disk device. Note that the broadcasting system 1 may include a plurality of advertising material storage devices 41.

As described above, the determining unit 130 determines whether the network After determining the CM identification code of the CM in the program to be distributed, the location (corresponding to advertisement identification information) of the CM advertising material 410 specified by the determined CM identification code is determined based on the advertising material location management table 136. The determining unit 130 associates the location of the advertising material 410 of the obtained CM with the CM trigger information of the CM, and outputs it to the SSAI server 12.

The replacement unit 121 in the SSAI server 12 acquires the advertising material 410 from the location of the CM advertising material 410 in the advertising material storage device 41, which is input from the determining unit 130. The replacement unit 121 replaces the advertising material at the timing of the SCTE-35 signal indicated by the CM trigger information with the acquired advertising material 410. The replacement unit 121 delivers the SCTE-35 signal that has undergone the above-described replacement process to the viewer terminal device 42 via the CDN 40.

Next, the operation (processing) of the broadcasting system 1 according to this embodiment will be described in detail with reference to the flowcharts of FIGS. 5A and 5B.

The extraction unit 220 in the program distribution signal generation device 22 extracts CM trigger information and event ID from the broadcast signal generated by the broadcast signal generation device 21 (step S101). The adding unit 221 adds the CM trigger information and event ID extracted by the extracting unit 220 to the SCTE-35 signal, and transmits the SCTE-35 signal to the advertisement distribution device 10 (step S102).

The receiving unit 110 in the packager 11 of the advertisement distribution device 10 extracts CM trigger information and event ID from the SCTE-35 signal received from the program distribution signal generation device 22, and converts the extracted CM trigger information and event ID into SSAI. It is output to the AD server 13 via the server 12 (step S103). The attribute acquisition unit 120 in the SSAI server 12 receives information that can identify the viewer's attributes (for example, the viewer's ID) from the viewer terminal device 42, and uses the received information to AD identify the viewer's attributes. It is output to the server 13 (step S104).

The program information acquisition unit 132 in the AD server 13 acquires the program information 133 via a dedicated communication network that can communicate with the broadcast station system or as an EPG included in broadcast waves (step S105). However, there is no dependency between the timing at which step S105 is performed and the timing at which steps S101 to S104 are performed, and step S105 may be performed before step S106, which will be described later.

The determining unit 130 compares the event ID input from the receiving unit 110 with the program information 133 acquired by the program information acquiring unit 132, and acquires the content of the program indicated by the event ID (step S106). The determining unit 130 compares the acquired program content and viewer attributes with the criteria 131 (step S107).

In the criterion 131, if a commercial to be distributed online is not set for the combination of program content and viewer attributes (No in step S108), the determining unit 130 determines the location of advertising material 410 related to a commercial unrelated to the program. and the CM trigger information to the SSAI server 12 (step S109), and the process proceeds to step S111.

In the criterion 131, if a CM to be distributed over the Internet is set for the combination of program content and viewer attributes (Yes in step S108), the determining unit 130 determines the location of the advertising material 410 related to the CM to be distributed over the Internet. The SSAI server 12 is notified in association with the CM trigger information (step S110).

The replacement unit 121 in the SSAI server 12 acquires the advertising material 410 from the location of the advertising material 410 in the advertising material storage device 41 regarding the CM to be distributed over the internet, as notified by the determining unit 130 (step S111). The replacement unit 121 replaces the advertising material at the timing of the SCTE-35 signal indicated by the CM trigger information with the acquired advertising material 410, and then delivers the SCTE-35 signal to the viewer terminal device 42 (step S112). , the whole process ends.

The broadcasting system 1 according to the present embodiment can improve cost effectiveness regarding advertising when a program is distributed in parallel by broadcasting and a communication network. The first reason is that the program distribution signal generation device 22 according to the present embodiment extracts the event ID and CM trigger information from the broadcast signal of the program, associates the event ID and the CM trigger information, and generates the SCTE-35 This is because it is added to the signal. The second reason is that the advertisement distribution device 10 according to the present embodiment obtains the event ID and CM trigger information extracted from the broadcast signal of the program, further obtains the program information 133, and This is because the CM to be distributed over the Internet is determined based on the ID, program information 133, and standard 131, and the CM at the relevant timing of the SCTE-35 signal is replaced with the CM to be distributed over the Internet.

Below, effects realized by the broadcasting system 1 according to this embodiment will be explained in detail.

When starting a business that distributes broadcast programs in parallel over a communications network, it is important to make advertising as cost-effective as possible. That is, the challenge is to suppress the cost of repairing the broadcasting system associated with the start of such a business and to realize CM distribution control that improves advertising effectiveness.

To address this problem, the program distribution signal generation device 22 according to the present embodiment includes an extraction section 220 and an addition section 221, and operates as described above with reference to FIGS. 1 to 5B, for example. That is, when a program is distributed in parallel through broadcasting and a communication network, the extraction unit 220 extracts an event ID (program identification information) that can identify the program and CM trigger information for the program from the broadcast signal of the program. (information indicating the timing at which an advertisement is inserted) and are extracted. Then, the adding unit 221 associates the event ID with the timing and adds it to the SCTE-35 signal (a communication signal for distributing the program via the communication network).

Further, in order to solve the above-mentioned problem, the advertisement distribution device 10 according to the present embodiment includes a receiving section 110, a replacing section 121, a program information acquiring section 132, and a determining section 130, and includes, for example, FIGS. 1 to 5B. It operates as described above with reference. That is, when a program is distributed in parallel through broadcasting and a communication network, the receiving unit 110 uses an event ID (program identification information) that can identify the program, which is extracted from the broadcast signal of the program, and a CM trigger. information (information indicating the timing at which advertisements are inserted). The program information acquisition unit 132 acquires program information 133 representing the content of the program. The determining unit 130 determines advertisement identification information based on the event ID, the program information 133, and a predetermined criterion 131. Then, the replacement unit 121 replaces the advertising material at the relevant timing of the SCTE-35 signal (communication signal) that distributes the program by the CDN 40 (communication network) with the advertising material 410 indicated by the advertising identification information.

That is, in the broadcasting system 1 according to the present embodiment, the event ID and CM trigger information are extracted from the existing broadcast signal, and the extracted information is added to the SCTE-35 signal used for online distribution and utilized. , CM distribution control can be realized at low cost on the Internet distribution side in cooperation with the broadcasting side, without requiring large-scale system modification such as constructing a new system for Internet distribution.

Further, the advertisement distribution device 10 according to the present embodiment acquires the program information 133 via a dedicated communication network that can communicate with, for example, a broadcasting station system, and if the dedicated communication network is not constructed, The EPG included in the broadcast wave is acquired as program information 133. Therefore, the advertisement distribution device 10 can reliably acquire the program information 133.

Further, the advertisement distribution device 10 according to the present embodiment acquires information that allows identification of the viewer's attributes, and performs CM distribution control based on the viewer's attributes on the Internet distribution side. Thereby, the advertisement distribution device 10 can improve advertising effectiveness.

Further, the contents of the standard 131 used by the advertisement distribution device 10 according to the present embodiment are not limited to the contents described above. The standard 131 may include, for example, information that associates advertisement identification information on the broadcasting side and the internet distribution side with the distribution time of the program. More specifically, the criteria 131 may include information indicating that, for example, when the program distribution time is late at night, the Internet distribution side distributes a commercial with content more aimed at adults.

The advertisement distribution device 10 according to the present embodiment can further improve advertising effectiveness by performing flexible CM distribution control using the criteria 131 including the above-mentioned information.

Furthermore, the SCTE-35 signal output from the program distribution signal generation device 22 may be used in a manner different from that used by the advertisement distribution device 10 described above. For example, if you want to know the number of times commercials are distributed for each program on the broadcasting side, a device that has the function of handling SCTE-35 signals can analyze the SCTE-35 signals output from the program distribution signal generation device 22. The purpose can be achieved with a simple configuration.

Furthermore, in the broadcasting system 1, the program identification information is not limited to the event ID, and may be information different from the event ID.

Furthermore, in the broadcasting system 1, the communication signal on the network distribution side is not limited to the SCTE-35 signal, and may be a signal different from the SCTE-35 signal.

Further, the target to which the technology shown in this embodiment is applied is not limited to television broadcasting, but can also be applied to radio broadcasting.
