Description

  The present invention relates to a broadcast advertisement determination device and a broadcast advertisement determination program.

  2. Description of the Related Art Conventionally, television stations that broadcast television programs broadcast advertisements of companies that have signed a sponsor contract and broadcast advertisements for the purpose of promotion (so-called commercials, hereinafter referred to as CMs) between television programs. For example, a television station broadcasts a CM corresponding to the characteristics and environment of its broadcast area.

  In addition, as part of the sales operation to install a sponsorship contract to obtain the right to broadcast commercials, a television advertisement survey is conducted to investigate what sponsor's commercials are flowing in other stations between television programs. Yes. For example, the CM is divided into a net CM broadcast from a main network station and affiliated local stations, and a local CM broadcast from only one of the above-mentioned network stations or local stations.

  For example, the local station captures a broadcast wave of another station and extracts a CM portion from the captured broadcast wave. Then, the local station acquires program information of the program broadcast on the other station, and uses the acquired program information to investigate the type of CM extracted from the broadcast wave of the other station. For example, the local station determines that the extracted time of the CM extracted from the broadcast wave of the other station is the broadcast time zone of the net program from the program information, and determines that it is a net CM. Also, the local station determines that it is a local CM when it is specified from the program information that the extraction time of the CM extracted from the broadcast wave of the other station is the broadcast time zone of the local program. The local station identifies a local CM that is not broadcasted on its own station based on the CM advertisement survey result, and conducts sales for the sponsor of the identified local CM to broadcast the CM on its own station. Note that a net program is a program broadcast from a main network station or affiliated local station, and a local program is a program broadcast from only one of the above-mentioned network stations or local stations. is there.

  By the way, the program information used in the above-described CM placement survey is not timely information. For example, even if it is a broadcast time zone of a net program on program information, a local program may actually be broadcast. For this reason, the local station is currently conducting a CM placement survey after manually modifying the program information into timely information, and there is a problem that the work load is large.

  Therefore, for the purpose of reducing the work burden of the CM placement survey, whether the CM is a net CM based on the collation result between the CM image data broadcast on the own station and the CM image data captured from the net station at the same time. A CM discriminating method for discriminating whether the CM is a local CM can be considered. For example, according to this CM discrimination method, if the CM image data matches, it can be determined as a net CM, and if it does not match, it can be determined as a local CM.

  However, in the local station, for example, for the reason of program organization, the net program being broadcast on the net station is recorded without being broadcast in real time (so-called endorsement), and in a time zone different from the broadcast time by the net station. There is a case to broadcast. In the above-described CM discrimination method that simply compares the CM image data, since the shift of the broadcast time is not taken into account, the CM type (net or local) cannot be accurately discriminated.

  The disclosed technology has been made in view of the above, and an object thereof is to provide a broadcast advertisement determination device and a broadcast advertisement determination program that can easily and accurately determine the type of CM.

  In one aspect, the technology disclosed in the present application includes a first input unit that inputs image information of a first broadcast advertisement broadcasted from a local station, and image information of a second broadcast advertisement broadcasted from a key station. A first input unit for acquiring broadcast advertisement image information broadcasted in a network program from among the second input unit for inputting the image and the image information of the first broadcast advertisement input by the first input unit. A second part that acquires image information of a broadcast advertisement in a time zone during which the same program as the net program was broadcasted from the image information of the second broadcast advertisement input by the acquisition unit and the second input unit. Based on the collation result of the image information by the collation unit, the collation unit that collates the image information acquired by the acquisition unit, the image information acquired by the first acquisition unit, and the image information acquired by the second acquisition unit And a determination unit for determining a type of the first broadcast advertisement Having.

The data server 140 fetches CM data from the PCs 111a to 131c at a predetermined timing (for example, daily unit, weekly unit), and loads the captured CM data (CM image data and image feature data) to each network station (for example, A , B, C) for each time series.

  Then, the data server 140 transmits the CM data stored in time series for each network station to the media research server 300 via the network 10. For example, the data server 140 may automatically transmit the CM data to the media research server 300 at a timing set by default, or may transmit the CM data in response to a request from the media research server 300. You may do it.

  As shown in FIG. 2, capture apparatuses 210a to 230c, PCs (Personal Computers) 211a to 231c, a data server 240, and a media research server 300 are installed at the Fukuoka head office. The capture devices 210a to 230c perform the same operation as the capture devices 110a to 130c of the Tokyo branch office described above. That is, the capture devices 210a to 230c capture broadcast data of local stations that have bases near the Fukuoka head office. For example, the capture device 210a captures broadcast data broadcast from the D station that is an affiliated local station of the A station that is the network station, that is, from the Fukuoka head office. The capture device 220b captures broadcast data of station E, which is an affiliated local station of station B, which is a network station. Capture device 230c captures broadcast data of station F, which is an affiliated local station of station C, which is a network station. To capture.

  The data server 240 performs the same operation as the data server 140 of the Tokyo branch office described above. That is, the data server 240 fetches the CM data from the PCs 211a to 231c at a predetermined timing (for example, daily unit, weekly unit), and loads the captured CM data (CM image data and image feature data) into each local station (for example, , D, E, and F stations) in time series.

  Then, the data server 240 transmits the CM data stored in time series for each local station to the media research server 300 via the network 10. For example, the data server 240 may automatically transmit the CM data to the media research server 300 at a timing set by default, or may transmit the CM data in response to a request from the media research server 300. You may do it.

  FIG. 3 is a diagram illustrating a configuration of the media research server according to the second embodiment. The media research server 300 determines the type of CM data captured at the Fukuoka branch office based on the CM data of the network station captured at the Tokyo branch office and the CM data of the local station captured at the Fukuoka head office. The media research server 300 includes, for example, a communication control unit 310, an input unit 320, an output unit 330, a storage unit 340, and a control unit 350, as shown in FIG.

  The communication control unit 310 controls communication regarding CM data exchanged between the data server 140 installed in the Tokyo branch office and the data server 240 installed in the Fukuoka head office.

  The input unit 320 includes input devices such as a keyboard, a mouse, and a microphone, for example, and receives input operations related to various settings from an administrator. For example, the input unit 320 receives from the administrator an input operation of a time difference between broadcast times when the same network program is broadcast between the local station and the network station. Then, the input unit 320 sends the input shift time to a shift information setting unit 351 described later.

  The output unit 330 outputs various information in response to a request from the administrator. The output unit 330 includes, for example, a monitor and a display, and outputs various information in response to a request from the administrator. For example, the output unit 330 displays a setting screen for setting the shift time. The output unit 330 displays program information including the broadcast schedule, program contents, and shift time of the local station's net program.

  The storage unit 340 stores data and programs necessary for various processes by the control unit 350, and includes, for example, a program guide data storage unit 341 and a CM data storage unit 342 as shown in FIG.

  The program guide data storage unit 341 stores program information in which net program information broadcast from a local station is associated with a time difference between broadcast times at which the same net program is broadcast between the local station and the net station. .

  FIG. 4 is a diagram illustrating an example of data stored in the program guide data storage unit according to the second embodiment. As shown in the figure, the program guide data storage unit 341 stores, for each local station, the net program information of the broadcast net program in association with the broadcast time of the net program of each day of the week. For example, as shown in the figure, the program guide data storage unit 341 stores the net program information of a certain net program in association with the broadcasting time zone of “17:00 to 18:00” on Monday of station D. . Here, in this net program information, “+90 minutes” is stored as the deviation time. However, in “+90 minutes”, the same net program is broadcast on the local station with a delay of 90 minutes from the start of broadcasting of the net station. Indicates that In addition, for example, the program information may be updated for each period (so-called cool) in which information about a net program corresponding to a one-week broadcast schedule is changed in program organization.

  The CM data storage unit 342 stores information regarding the CM data of the network station received from the data server 140 and information regarding the CM data of the local station received from the data server 240.

  FIG. 5 is a diagram illustrating an example of data stored in the CM data storage unit according to the second embodiment. As shown in the figure, the CM data storage unit 342 stores a file name, CM image data, and image feature data in association with the broadcast date and time for each local station and each network station. The CM image data includes a CM image data file and a CM type (local or net). “Local” indicates a local CM broadcast from only one local station. “Net” indicates a CM broadcast from a plurality of broadcasting stations including a local station of an affiliated group based on a certain net station.

  The storage unit 340 is, for example, a semiconductor memory device such as a RAM (Random Access Memory), a ROM (Read Only Memory), or a flash memory, or a storage device such as a hard disk or an optical disk.

  The control unit 350 has an internal memory for storing a predetermined control program, a program that defines various processing procedures, and required data, and executes various processes using these. And the control part 350 has the shift information setting part 351 and the CM data discrimination | determination part 352, for example, as shown in FIG.

  The shift information setting unit 351 receives, from the administrator, the setting of the time difference between broadcast times at which the same net program is broadcast between the local station and the net station for the net program broadcast at each local station. The data is stored in the table data storage unit 341.

  For example, the shift information setting unit 351 reads program information from the program guide data storage unit 341 in accordance with an operation of the administrator, processes the read program information, and displays the processed program information via the output unit 330. Output. FIG. 6 is a diagram illustrating a display example of program information according to the second embodiment. The shift information setting unit 351 displays and outputs program information as shown in FIG. 6, for example, in response to an operation from the administrator. In FIG. 6, program information including a shift time (shift: + ˜) is displayed for each program. This shift time is displayed after setting by the administrator described below. And

  For example, when the shift information setting unit 351 accepts the selection of the net program “shomon time” from the administrator on the program information shown in FIG. 6, a setting screen as shown in FIG. 7 is displayed via the output unit 330. Display output. FIG. 7 is a diagram illustrating an example of a shift time setting screen according to the second embodiment. As shown in the figure, the setting screen includes “program name”, “net station broadcast time”, “local station broadcast time”, “how many days after the net station broadcast date”, “net station broadcast time” Input fields for “shift time”, “target period”, and “target day of the week” are provided.

  Note that the shift information setting unit 351 selects “program name: shomon time”, “local station broadcast time: 17: 00-19: 00”, “target period: 2008/04/01” when the administrator selects an online program. -2008/09/30 "and" Target day of the week: Wednesday "are automatically entered. Then, the shift information setting unit 351 selects “program name: shomon time”, “local station broadcast time: 17: 00-19: 00”, “target period: 2008 / "04 / 01-2008 / 09/30" and "Target day of the week: Wednesday" are provided to the administrator. The shift information setting unit 351 includes “Internet station broadcasting time: 15: 00-17: 00”, “How many days after the network station broadcasting date: 0 (day)”, “Shift time from network station broadcasting time: +120 When the input of “” is received from the administrator, it is stored in the program guide data storage unit 341. Then, the program information including the shift time (shift: +120 ') in the net program "Sakumon Time" is again displayed and output.

  Further, for example, when the shift information setting unit 351 accepts the selection of the net program “Comical G” from the administrator on the program information shown in FIG. 6, the above-described net program “laughing time” is output via the output unit 330. As in the case of selecting “”, a setting screen as shown in FIG. 8 is displayed and output. FIG. 8 is a diagram illustrating an example of a shift time setting screen according to the second embodiment. Then, the shift information setting unit 351 displays “network station broadcasting time: 16: 00-17: 00”, “how many days after the network station broadcasting date: 0 (day)”, “shift time from the network station broadcasting time” : +60 '"is received from the administrator, it is stored in the program guide data storage unit 341. Then, the program information including the shift time (shift: +60 ') in the net program "Comical G" is again displayed and output.

  The CM data discriminating unit 352 performs a collation process between the CM data of the network station and the CM data of the local station, and executes a CM discrimination process for discriminating the CM type of the local station. For example, the CM data determination unit 352 waits for arrival at the start timing of the CM determination process. The start timing of the CM discrimination process is set, for example, by receiving an instruction to start the CM discrimination process from the administrator, or a preset start time of the CM discrimination process (for example, a time zone during which no CM data is captured) Time) can be used.

  When the start timing of the CM discrimination process is reached, the CM data discriminating unit 352 acquires program information of a net program of a certain local station from the program guide data storage unit 341. For example, taking FIG. 4 as an example, the CM data discriminating unit 352 acquires the program information of the online program “Laughing News” broadcast on Sundays from “18:00 to 19:00” at the local station D. To do.

  After acquiring the program information, the CM data discriminating unit 352 extracts CM data in the broadcast time zone corresponding to the acquired program information of a certain local station from the CM data storage unit 342. FIG. 9 is a diagram for explaining the process of the CM data determination unit according to the second embodiment. For example, when the CM data discriminating unit 352 acquires the program information of the network program broadcast from “18:00 to 19:00” at the local station D, as shown in the lower left of FIG. : 00-19: 00 ", the five CM data broadcasted by the D station are extracted from the CM data storage unit 342. Note that each CM data shown in the lower left of the figure is described as displaying information related to “net CM” or “local CM”, but it is determined after the processing by the CM data discriminating unit 352 is completed. This information is not displayed when CM data is extracted.

  After extracting the CM data of the local station, the CM data determining unit 352 extracts the CM data of the corresponding network station from the CM data storage unit 342 based on the acquired program information of a certain local station. For example, the CM data discriminating unit 352 acquires the program information of the network program broadcast from “18:00 to 19:00” at the local station D, and the shift time associated with the acquired program information is “+60”. If “”, the process is as follows. That is, the CM data discriminating unit 352 advances the network program time zone “18:00 to 19:00” at the D station of the local station by 60 minutes to “17” at the A station that is the net station corresponding to the D station. : 5 to 18:00 ”, the five CM data broadcasted in the time zone are extracted from the CM data storage unit 342 (see FIG. 9 (1)).

  Then, the CM data determination unit 352 acquires a set of image feature data of the network station and the local station having the same broadcast time from the CM data of the local station and the network station extracted from the CM data storage unit 342, and acquires the acquired image. Match feature data. For example, the CM data discriminating unit 352 first corrects the broadcast time corresponding to the image feature data of the network station by 60 minutes to match the time conditions of the local station and the network station (see FIG. 9 (2)). After matching the time conditions, the CM data discriminating unit 352 collates the image feature data of the network station and the local station whose broadcast times match (see (3) in FIG. 9). When the collation degree between the image feature data obtained as a result of the collation exceeds a predetermined threshold (when “OK” shown in FIG. 9), the CM data discriminating unit 352 Process as follows. That is, the CM data discriminating unit 352 sets information indicating “net CM” as the CM type of the local station CM that has obtained a predetermined matching degree with the CM data of the net station. Then, the CM data determination unit 352 stores the CM type set in the CM data of the local station, that is, information indicating “net CM” in association with the CM data stored in the CM data storage unit 342. .

  On the other hand, when the degree of matching between image feature data obtained as a result of matching is equal to or less than a predetermined threshold (when “NG” shown in FIG. 9), the CM data determining unit 352 Process like this. That is, the CM data discriminating unit 352 sets information indicating “local CM” as the CM type of the CM of the local station for which a predetermined matching degree with the CM data of the network station is not obtained. Then, the CM data determination unit 352 stores the CM type set in the CM data of the local station, that is, information indicating “local CM” in association with the CM data stored in the CM data storage unit 342. .

  The CM data discriminating unit 352 determines whether or not the processing described above has been completed for the CM data of the net station and the local station extracted from the CM data storage unit 342, that is, each CM data broadcast in the net program. . As a result of the determination, if the processing described above for each CM data in the same network program has not been completed, the CM data determination unit 352 executes the processing described above for the remaining CM data in the same network program. .

  On the other hand, as a result of the determination, the CM data discriminating unit 352 adds the program guide data stored in the program guide data storage unit 341 to the program guide data when the above-described processing is completed for each CM data in the network program. It is determined whether there is a broadcast time zone of an unprocessed net program. As a result of the determination, if there is a broadcast time zone of an unprocessed net program, the CM data discriminating unit 352 executes the processing described above for each CM data broadcast in the broadcast time zone of the remaining net program. On the other hand, if the result of determination is that there is no broadcast time zone for an unprocessed net program, the CM data determination unit 352 ends the CM determination process.

  The control unit 350 is, for example, an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA), or an electronic circuit such as a central processing unit (CPU) or a micro processing unit (MPU).

  As described above, the CM data discriminating unit 352 is endorsed by the local station using the time difference (shift time) of the broadcast time at which the same net program is broadcast between the local station and the net station. Then, the CM data of the network station corresponding to the CM data broadcast is extracted. However, the present invention is not limited to this, and for example, when there is a common identification code or the like common to a net program broadcast on a local station and a net station, it can be handled without setting a shift in broadcast time. CM data of network stations can be extracted. That is, the CM data discriminating unit 352 specifies a time zone in which a matching net program was broadcast on the network station based on the identification code of a certain network program broadcast on the local station. When the CM data discriminating unit 352 extracts the CM data broadcast on the network station in the specified time zone from the CM data storage unit 342, it is endorsed by the local station and broadcasted as in the case of using the shift time. The CM data of the network station corresponding to the CM data thus obtained can be extracted.

[Processing in Example 2]
FIG. 10 is a diagram illustrating a process flow of the media research server according to the second embodiment. As shown in the figure, for example, the CM data discriminating unit 352 waits for arrival at the start timing of the CM discriminating process (step S1). When the start timing of the CM discrimination process is reached (Yes at step S1), the CM data discrimination unit 352 acquires program information of a net program with a certain local station from the program guide data storage unit 341 (step S2).

  After acquiring the program information, the CM data discriminating unit 352 extracts CM data in the broadcast time zone corresponding to the acquired program information of a certain local station from the CM data storage unit 342 (step S3). After extracting the CM data of the local station, the CM data discriminating unit 352 extracts the CM data of the corresponding net station from the CM data storage unit 342 based on the acquired program information of a certain local station (step S4). For example, the CM data discriminating unit 352 acquires the program information of the network program broadcast from “18:00 to 19:00” at the local station D, and the shift time associated with the acquired program information is “+60”. If “”, the process is as follows. That is, the CM data discriminating unit 352 advances the network program time zone “18:00 to 19:00” at the D station of the local station by 60 minutes to “17” at the A station that is the net station corresponding to the D station. CM data broadcast in the time zone of “: 00 to 18:00” is extracted from the CM data storage unit 342.

  After the CM data is extracted, the CM data discriminating unit 352 acquires a set of image feature data of the net station and the local station having the same broadcast time from the CM data of the local station and the net station extracted from the CM data storage unit 342. The acquired image feature data is collated (step S5). Then, the CM data determination unit 352 determines whether or not the degree of matching between image feature data obtained as a result of matching exceeds a predetermined threshold (step S6).

  As a result of the determination, when the collation degree between the image feature data obtained as a result of the collation exceeds a predetermined threshold (Yes at Step S6), the CM data discriminating unit 352 is “net CM” in the CM data of the local station. Information to that effect is set (step S7). On the other hand, when the matching degree between the image feature data obtained as a result of the matching is equal to or less than a predetermined threshold (No at Step S6), the CM data determination unit 352 adds “Local CM” to the CM data of the local station. Is set (step S8).

  Subsequent to step S7 or S8, the CM data determination unit 352 executes the process of step S9. That is, the CM data discriminating unit 352 determines whether or not the above-described processing has been completed for the CM data of the net station and the local station extracted from the CM data storage unit 342, that is, each CM data broadcast in the net program. Determine (step S9). As a result of the determination, if the above-described processing has not been completed for each CM data in the same Internet program (No at Step S9), the CM data discriminating unit 352 has described the remaining CM data in the same Internet program. Steps S5 to S8 are executed.

  On the other hand, as a result of the determination, when the processing described above has been completed for each CM data in the same network program as a result of the determination (Yes at Step S9), the CM data determination unit 352 executes the processing at Step S10. That is, the CM data discriminating unit 352 determines whether or not the program schedule data stored in the program schedule data storage unit 341 includes an unprocessed network program broadcast time zone (step S10). As a result of the determination, if there is a broadcast time zone of an unprocessed net program (Yes at step S10), the CM data discriminating unit 352 has been described above for each CM data broadcast in the broadcast time zone of the remaining net program. The process from step S2 to step S9 is executed. On the other hand, if there is no broadcast time zone of the unprocessed net program as a result of the determination (No at Step S10), the CM data determining unit 352 ends the CM determining process.

  Note that the processing flow of the media research server described above does not necessarily have to be performed in the order shown in FIG. For example, in the processes of step S3 and step S4 in the figure, the process of step S4 may be executed before step S3, or the processes of step S3 and step S4 may be executed in parallel.

[Effects of Example 2]
As described above, according to the second embodiment, the media research server 300 acquires the CM image broadcast in the local station net program, and the CM of the net station in the time zone in which the same net program is broadcast. Acquire images and collate the acquired CM images. For this reason, the type of CM can be determined easily and accurately. That is, the media research server 300 includes a program guide data storage unit 342 that stores program information that associates a time difference between broadcast times at which the same network program is broadcast between the local station and the key station. Therefore, the media research server 300 can easily acquire the CM image of the net station in the time zone in which the net program broadcast on the local station was broadcast based on the shift time acquired from the program guide data storage unit 342. As a result, it is possible to avoid a situation in which a CM image that should be successfully collated fails to collate when a CM image in a net program broadcast at a local station with a time lag is collated. The type of CM can be determined easily and accurately.

(1) Apparatus Configuration, etc. For example, each component of the media research server 300 shown in FIG. 3 is functionally conceptual and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution / integration of the media research server 300 is not limited to the one shown in the figure. For example, the CM data determination unit 352 is functionally combined with a function unit for extracting CM data and a function unit for comparing CM data. It may be physically dispersed. As described above, all or a part of the media research server 300 can be configured to be functionally or physically distributed / integrated in an arbitrary unit according to various loads or usage conditions.

(2) Broadcast Advertisement Discrimination Program Various processes (see FIG. 10) of the media research server 300 described in the above embodiment are executed by a computer system such as a personal computer or a workstation. Can also be realized.

  In the following, an example of a computer that executes a broadcast advertisement determination program having the same function as the media research server 300 described in the above embodiment will be described with reference to FIG. FIG. 11 is a diagram illustrating a computer that executes a broadcast advertisement determination program.

  As shown in the figure, a computer 400 as the media research server 300 is configured by connecting a communication control unit 410, an HDD 420, a RAM 430, and a CPU 440 via a bus 500.

  Here, the communication control unit 410 controls communication related to the exchange of various types of information. The HDD 420 stores information necessary for the CPU 440 to execute various processes. The RAM 430 temporarily stores various information. The CPU 440 executes various arithmetic processes.

  As shown in FIG. 11, the HDD 420 stores in advance a broadcast advertisement determination program 421 that performs the same function as each processing unit of the media research server 300 shown in FIG. 3 and broadcast advertisement determination data 422. Has been.

  Note that the broadcast advertisement determination program 421 can be appropriately distributed and stored in a storage unit of another computer that is communicably connected via a network.

  Then, the CPU 440 reads out the broadcast advertisement determination program 421 from the HDD 420 and develops it in the RAM 430, so that the broadcast advertisement determination program 421 functions as a broadcast advertisement determination process 431 as shown in FIG.

  That is, the broadcast advertisement determination process 431 reads out the broadcast advertisement determination data 422 and the like from the HDD 420, expands them in an area allocated to itself in the RAM 430, and executes various processes based on the expanded data and the like.

  The broadcast advertisement determination process 431 particularly corresponds to processing executed in the shift information setting unit 351 and the CM data determination unit 352 of the media research server 300 shown in FIG.

  Note that the broadcast advertisement determination program 421 described above is not necessarily stored in the HDD 420 from the beginning. For example, each program is stored in a “portable physical medium” such as a flexible disk (FD), a CD-ROM, a DVD disk, a magneto-optical disk, and an IC card inserted into the computer 400. Then, the computer 400 may read and execute each program from these.

  Further, each program is stored in “another computer (or server)” connected to the computer 400 via a public line, the Internet, a LAN, a WAN, or the like. Then, the computer 400 may read and execute each program from these.
