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.

JP2003-13489A

  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 the program information, a local program may actually be broadcast for reasons of program organization. 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, for the purpose of broadcasting commercials in line with the regional characteristics of the broadcasting area, the above-mentioned net commercials are broadcast on the net station and local station even though the sponsors are the same. There are net replacement CMs with different contents of the net CM. For example, as an example of an internet replacement CM, a local station based in a cold region broadcasts a CM of a warm-colored car, and a network station based on a warm region broadcasts a CM of a cold-colored car. Etc. are raised. For this reason, there is a problem that the net replacement CM cannot be discriminated by the CM discriminating method for discriminating whether it is a net CM or a local CM by simply collating with the CM image data.

  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 capable of determining the type of CM in detail up to a net replacement 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 broadcast from a local station, and a key station at a time when the first broadcast advertisement is broadcast. A second input unit that inputs image information of a second broadcast advertisement broadcast from the first acquisition unit that acquires sponsor information of the first broadcast advertisement, and sponsor information of the second broadcast advertisement. A first acquisition unit that acquires image information of the first broadcast advertisement and image information of the second broadcast advertisement, sponsor information of the first broadcast advertisement, , A second collating unit that collates sponsor information of the second broadcast advertisement, a collation result of the image information of the first broadcast advertisement and the image information of the second broadcast advertisement, and the first Sponsor information of broadcast advertisement and sponsor of the second broadcast advertisement On the basis of the collation result of the information, having a determination unit for determining a type of the first broadcast advertisement.

  According to one aspect of the technology disclosed in the present application, CMs broadcast on other broadcast stations can be discriminated in detail up to a net replacement CM.

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 make it do.

  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 PCs 211a to 231c perform the same operations as the PCs 111a to 131c of the Tokyo branch office described above. That is, the PCs 211a to 231c take in broadcast data from the capture devices 210a to 230c, extract CM data from the broadcast data, and store the extracted CM data in time series. For example, the PC 211a captures broadcast data from the capture device 210a, and extracts CM image data from the broadcast data based on a silent portion provided at the beginning and end of the CM data or a change in luminance of the image when switching to the CM data. To do. Further, the PC 211a generates image feature data for performing edge (contour) collation (hereinafter referred to as “collation” agrees with “edge collation”) from the extracted CM image data. This image feature data is used for collation of CM data by the media research server 300 described later. Then, for example, the PC 211a stores the CM image data and the image feature data in time series in association with the broadcast time of the broadcast data.

  Similar to the PC 211a, the PC 221b captures broadcast data from the capture device 220b, extracts CM image data, generates image feature data, and associates the CM image data and image feature data with the broadcast time of the broadcast data. Save to series. Similarly to the PC 211a, the PC 231c takes in broadcast data from the capture device 230c, extracts CM image data, generates image feature data, and associates CM image data and image feature data with the broadcast time of the broadcast data. Are stored in chronological order.

  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 300 according to the second embodiment. The media research server 300 determines the type of the CM data captured at the Fukuoka head 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, when the input unit 320 receives an input operation of a sponsor name for CM data captured at the Fukuoka head office from an administrator, the input unit 320 sends the input sponsor name to a sponsor name setting unit 352 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 and outputs a screen for setting and inputting a sponsor name for the CM data.

  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 information on the program contents of each local station whose broadcast data is captured by the Fukuoka head office. 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, information indicating whether the program to be broadcast is a net program or a local program in association with a broadcast time of one hour. .

  For example, as shown in FIG. 4, the program guide data storage unit 341 includes the broadcasting times “6:00 to 7:00”, “7: 0 to 8:00”, “8:00 to 9:00” of the D station. "Net" is stored in association with each other. The program guide data storage unit 341 stores “local” in association with the broadcasting time “25:00 to 26:00” of the D station. That is, in the D station, the “net program” is broadcast at the broadcast times “6:00 to 7:00”, “7:00 to 8:00”, and “8:00 to 9:00”, and the broadcast time “25”. : 00 to 26:00 "indicates that the" local program "will be broadcast.

  For example, as shown in FIG. 4, the program guide data storage unit 341 associates “local” with the broadcast times “6: 0 to 7:00” and “25:00 to 26:00” of the E station. Is memorized. In addition, the program guide data storage unit 341 stores “net” in association with “7:00 to 8:00” and “8:00 to 9:00”, respectively. That is, in the E station, the “local program” is broadcast at the broadcast times “6:00 to 7:00” and “25:00 to 26:00”, and the broadcast times “7:00 to 8:00” and “8” : "00 to 9:00" indicates that the "net program" will be broadcast.

  Further, for example, as shown in FIG. 4, the program guide data storage unit 341 has the broadcasting times “6: 0 to 7:00”, “8:00 to 9:00”, and “25:00 to 26” of the F station. : ”Is stored in association with“ 00 ”. In addition, the program guide data storage unit 341 stores “net” in association with “7:00 to 8:00”. That is, in the F station, the “local program” is broadcast at the broadcast times “6:00 to 7:00”, “8:00 to 9:00”, and “25:00 to 26:00”, and the broadcast time “7” : "00 to 8:00" indicates that the "net program" will be broadcast.

  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, a sponsor name corresponding to the CM image, and a CM type (local, net, net replacement). The sponsor name is stored when the sponsor name is set and inputted by the administrator, and the CM type is data stored when processing by the CM data determination unit 353 described later is completed. “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. “Net replacement” refers to a CM that corresponds to the same sponsor, but has different contents broadcasted between the network station and the affiliated local station.

  FIG. 6 is a diagram illustrating an example of file names stored in the CM data storage unit according to the second embodiment. For example, the file name is described as “CM — 2009029080500.wmv” as shown in the uppermost part of FIG. “20090229080500” included in the file name indicates a broadcast date and time “February 29, 2009, 8: 5: 00”, and “wmv” indicates a moving image format, for example, “Windows (registered trademark) Media Video”.

  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. The control unit 350 includes, for example, a CM data extraction unit 351, a sponsor name setting unit 352, and a CM data determination unit 353 as illustrated in FIG.

  Based on the program guide data stored in the program guide data storage unit 341, the CM data extraction unit 351 generates CM data (broadcast within the network program) from the CM data stored in the CM data storage unit 342. Network CM data) to be extracted. For example, when there is an instruction to start CM discrimination processing, the CM data extraction unit 351 acquires the broadcast time zone of a certain station's net program from the data stored in the program guide data storage unit 341. Then, the CM data extraction unit 351 stores the acquired local station of the broadcast time of the net program and the CM data (broadcast date / time, image data, image feature data) of the corresponding net station in the CM data storage unit 342. Extract from existing data.

  For example, as shown in FIG. 4, the CM data extraction unit 351 determines the broadcast time zone “6: 00 to 00” of the network program of the D station that is the local station from the program guide data stored in the program guide data storage unit 341. 7:00 "is acquired. Then, for example, as shown in FIG. 5, the CM data extraction unit 351 obtains the CM data of the D station in the broadcast time zone “6: 0 to 7:00” of the acquired net program, and the net station corresponding to the D station. Is extracted from the CM data storage unit 342.

  When the CM data extraction unit 351 completes the extraction of the CM data, the sponsor name setting unit 352 causes the administrator to set a sponsor name corresponding to each CM. For example, the sponsor name setting unit 352 displays and outputs a screen to which the CM image data of each CM data extracted by the CM data extraction unit 351 is attached to the output unit 330, and causes the administrator to input a sponsor name corresponding to the CM. To set the sponsor name.

  FIG. 7 is a diagram illustrating an example of a sponsor name setting screen according to the second embodiment. As shown in the figure, the sponsor name setting screen is provided with a field for setting and inputting a sponsor name for each CM image data attached and displayed in the leftmost column. For example, if the administrator inputs the sponsor name “Company A” for the CM shown in the top row of the figure, the sponsor name setting unit 352 sets the sponsor name of the CM in the top row of the figure to “Company A”. To do. The sponsor name setting unit 352 stores the set sponsor name in association with the CM data stored in the CM data storage unit 342.

  The sponsor name setting unit 352 does not cause the administrator to set the sponsor name corresponding to the CM when the sponsor name data is prepared to some extent in the CM data stored in the CM data storage unit 342. It can also be set automatically. For example, the sponsor name setting unit 352 compares the image feature data of each CM data extracted by the CM data extraction unit 351 with the image feature data of the CM data stored in the CM data storage unit 342. When the matching degree between the image feature data exceeds a predetermined threshold, the sponsor name setting unit 352 uses the sponsor name stored in the CM data storage unit 342 in association with the corresponding image feature data as the CM name. The CM data extracted by the data extraction unit 351 is automatically set. The sponsor name setting unit 352 stores the automatically set sponsor name in association with the CM data stored in the CM data storage unit 342.

  When the sponsor name setting unit 352 completes the sponsor name setting, the CM data determining unit 353 performs a collation process between the CM data of the net station extracted by the CM data extracting unit 351 and the CM data of the local station, and the local station The CM type is determined.

  8 to 10 are diagrams illustrating processing performed by the CM data determination unit according to the second embodiment. For example, the left figure shown in FIG. 8 shows a state in which CM data of local stations (head office capture data) captured at the Fukuoka head office are arranged in time series from the top together with the sponsor name. The right figure shown in the figure shows a state in which CM data (Tokyo capture data) of network stations captured at the Tokyo branch office are arranged in time series from the top.

  For example, the CM data discriminating unit 353 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 net station and the local station extracted by the CM data extracting unit 351, and acquires them. Match image feature data. For example, when image feature data of a network station and a local station having the same broadcast time are collated, and the degree of collation between the image feature data obtained as a result of the collation exceeds a predetermined threshold (when “OK” shown in FIG. 8). The CM data determination unit 353 performs the following process.

  That is, as shown in FIG. 8, the CM data discriminating unit 353 indicates “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. Set the information. Then, the CM data determination unit 353 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. . Further, the CM data discriminating unit 353 determines the sponsor name set in the CM data of the local station, which has obtained a predetermined matching degree with the CM data of the network station, from the CM data of the local station. Is automatically set in the CM data of the net station for which the matching degree is obtained. Then, the CM data determination unit 353 stores the sponsor name set in the CM data of the network station in association with the CM data stored in the CM data storage unit 342.

  On the other hand, when the matching degree between the image feature data of the network station and the local station is equal to or less than a predetermined threshold (when “NG” shown in FIG. 8), the CM data determination unit 353 performs the following process. That is, as shown in FIG. 9, the CM data discriminating unit 353 displays and outputs on the output unit 330 a screen attached with the CM image data of the net station whose matching degree between the image feature data is equal to or less than a predetermined threshold value. Have the administrator set the sponsor name corresponding to each CM. For example, when the sponsor name “Company C” is input by the administrator for the CM shown in the second row from the top in the figure, the CM data discriminating unit 353 causes the CM sponsor shown in the second row from the top in the figure. Set the name to “Company C”. Then, the CM data determination unit 353 stores the set sponsor name in association with the CM data stored in the CM data storage unit 342.

  Note that the CM data determination unit 353 may automatically set the sponsor name corresponding to the CM instead of causing the administrator to set the sponsor name in the same manner as the sponsor name setting unit 352 described above.

  When the setting of the sponsor name to the CM of the network station that has not obtained a predetermined matching degree with the CM data of the local station is completed, the CM data determination unit 353 performs the following process. That is, the CM data discriminating unit 353 determines whether or not the sponsor name corresponding to the CM of the net station for which the predetermined matching degree is not obtained matches the sponsor name corresponding to the CM of the local station. If the sponsor names match as a result of the determination, the CM data discriminating unit 353, for example, as shown in FIG. 10, displays information indicating that “the net replacement CM” is the CM type of the local station CM. Set. Then, the CM data determination unit 353 associates the CM type set in the CM data of the local station, that is, information indicating “net replacement CM” with the CM data stored in the CM data storage unit 342. Store.

  On the other hand, if the sponsor name does not match as a result of the determination, the CM data discriminating unit 353 displays, for example, information indicating “local CM” as the CM type of the local station CM as shown in FIG. Set. Then, the CM type set in the CM data of the local station, that is, information indicating “local CM” is stored in association with the CM data stored in the CM data storage unit 342.

  The CM data discriminating unit 353 determines whether or not the above-described processing has been completed for the CM data of the net station and the local station extracted by the CM data extracting unit 351, that is, each CM data broadcast in the net program. To do. As a result of the determination, when the processing described above for each CM data in the same net program is not completed, the CM data determination unit 353 executes the processing described above for the remaining CM data in the same net program. .

  On the other hand, as a result of the determination, the CM data discriminating unit 353 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 353 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 353 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).

[Processing in Example 2]
FIG. 11 is a diagram illustrating a process flow of the media research server according to the second embodiment. As shown in the figure, the CM data extraction unit 351 receives, for example, an instruction to start CM discrimination processing from an administrator or the like, or the start timing of CM discrimination processing set by default (one day unit or one week unit) ) (Step S1).

  When receiving the instruction to start the CM discrimination process or confirming the arrival of the start timing of the CM discrimination process (Yes at step S1), the CM data extraction unit 351 receives the network program of a certain station from the program guide data storage unit 341. Is acquired (step S2). Then, the CM data extracting unit 351 extracts from the CM data storage unit 342 the local station of the broadcast time of the acquired net program and the CM data (broadcast date / time, image data, image feature data) of the corresponding net station ( Step S3).

  When the CM data extraction unit 351 completes the extraction of the CM data, the sponsor name setting unit 352 causes the administrator to set a sponsor name corresponding to each CM (step S4). For example, the sponsor name setting unit 352 displays and outputs a screen to which the CM image data of each CM data extracted by the CM data extraction unit 351 is attached to the output unit 330, and causes the administrator to input a sponsor name corresponding to the CM. To set the sponsor name.

  When the sponsor name setting unit 352 completes the sponsor name setting, the CM data determining unit 353 executes the process of step S5. That is, the CM data discriminating unit 353 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 net station and the local station extracted by the CM data extracting unit 351, and acquires the set. The image feature data is collated (step S5). Then, the CM data determination unit 353 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 collating the image feature data of the network station and the local station having the same broadcast time, if the degree of collation between the image feature data exceeds a predetermined threshold (Yes at step S6), the CM data determining unit 353 Process as follows. That is, the CM data discriminating unit 353 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 (step S7). ). Further, the CM data discriminating unit 353 determines the sponsor name set in the CM data of the local station, which has obtained a predetermined matching degree with the CM data of the network station, from the CM data of the local station. Is automatically set to the CM data of the network station from which the matching degree is obtained (step S8).

  On the other hand, as a result of collating the image feature data of the network station and the local station having the same broadcast time, if the degree of collation between the image feature data is less than or equal to a predetermined threshold (No at step S6), the CM data determining unit 353 Process as follows. That is, the CM data discriminating unit 353 displays and outputs on the output unit 330 a screen attached with the CM image data of the network station whose collation degree between the image feature data is equal to or less than a predetermined threshold, and the sponsor name corresponding to each CM. Is set by the administrator (step S9). Then, the CM data discriminating unit 353 determines whether or not the sponsor name corresponding to the CM of the network station for which the predetermined matching degree is not obtained matches the sponsor name corresponding to the CM of the local station (step S1). S10).

  As a result of the determination, if the sponsor names match (Yes at Step S10), the CM data determination unit 353 is “net replacement CM” as the CM type of the local station CM currently being processed. Information to that effect is set (step S11). On the other hand, as a result of the determination, if the sponsor names do not match (No at Step S10), the CM data determination unit 353 sets information indicating “local CM” as the CM type of the local station CM (Step S10). S12).

  Subsequent to step S8, S11, or S12, the CM data determination unit 353 executes the process of step S13. That is, the CM data discriminating unit 353 determines whether or not the above-described processing has been completed for the CM data of the net station and the local station extracted by the CM data extracting unit 351, that is, each CM data broadcast in the net program. Is determined (step S13). As a result of the determination, when the above-described processing has not been completed for each CM data in the same internet program (No at Step S13), the CM data discriminating unit 353 has explained the remaining CM data in the same internet program. Steps S5 to S12 are executed.

  On the other hand, as a result of the determination, the CM data determination unit 353 executes the process of step S14 when the process described above is completed for each CM data in the same network program (Yes in step S13). That is, the CM data discriminating unit 353 determines whether or not the program schedule data stored in the program schedule data storage unit 341 includes a broadcast time zone of an unprocessed net program (step S14). As a result of the determination, if there is a broadcast time zone of an unprocessed net program (Yes at step S14), the CM data discriminating unit 353 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 S13 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 S14), the CM data determining unit 353 ends the CM determining process.

  Note that the processing flow of the media research server 300 described above does not necessarily have to be performed in the order shown in FIG. For example, after setting the sponsor name shown in step S4 in the figure, the CM data to be processed shown in step S3 in the figure may be extracted. Also, the sponsor name setting shown in step S4 in the figure may be set at the timing when data is stored in the CM data storage unit 342 regardless of the flow of processing shown in the figure.

[Effects of Example 2]
As described above, according to the second embodiment, the media research server 300 uses the matching result of the sponsor name of each CM data as well as the matching result of the CM data of the local station and the CM data of the network station. To set the CM type of the local station. For this reason, according to the second embodiment, the type of CM can be determined in detail up to the net replacement CM.

  For example, when the CM images of the local station and the net station do not match each other and the sponsor names corresponding to the respective CM images match each other, the media research server 300 converts the local station CM to the net replacement CM. to decide. For this reason, the media research server 300 determines whether or not the sponsor name is the same, and further details the net replacement CM that has been conventionally determined as a local CM by matching the CM images. Can be determined.

  Further, according to the second embodiment, the media research server 300 stores the sponsor name corresponding to the CM image in the CM data storage unit 342, so that the media research server 300 easily obtains the sponsor name corresponding to the CM image. it can.
