Description

  The present invention relates to a CM survey system that surveys CMs included in a broadcast signal transmitted from a broadcast station and transmitted together with a program, and more particularly to a CM survey system that performs CM surveys for CMs of other stations.

Due to the slump in the mass media and the rise of the Internet, the advertising revenue of broadcasting stations has been declining, and the business model that depends on the advertising revenue of TVCM has been threatened.
In such a situation where TVCM advertising revenues in the industry as a whole are not expanding, the importance of securing advertisers is only increasing. In particular, securing new advertisers is important.

To that end, Tomei Osaka (key and quasi-key stations) will constantly conduct manual TV CM surveys with expensive commission contracts to determine whether CMs broadcast on other stations are being broadcast on their own stations. It is said.
JP 2001-357284 A JP-A-5-183887

  In the TVCM survey, the investigator views all the channels broadcast by other stations competing with the own station, and fills in the survey items. As the number of surveyed channels increases, the number of investigators is also required, and the cost is enormous. The survey items to be entered are the broadcast time, the advertiser, and the advertisement content for the TVCM of the other station. It is necessary to collate this entry content with the TVCM of the local station. Although the TVCM program of the local station has been clarified, the TVCM collation for determining whether or not the TVCM program of the local station is the same TVCM by comparing the input contents of the survey item depends on the input contents. Its reliability is not high. In addition, in the TVCMs of other stations, it is necessary to determine whether or not the same TVCM is the same in order to count the number of times of the same TVCM. Further, when the TVCM investigator and the person in charge of collation are different, the reliability is further lowered. In other words, the current survey method is not reliable, and it is not stable because it is conducted manually (results vary between survey results by inexperienced surveyors and survey results by experienced surveyors, The results of research conducted by the same investigator for a long time and the results of research conducted in shifts also vary), and the problem is that costs are excessive.

  Incidentally, Patent Document 1 discloses a system in which a media company such as a broadcasting station exchanges advertisement frames with each other. This system includes an advertising space input unit for inputting a promotional advertising space provided free of charge by the publisher to the organizer, an advertising space storage unit for storing the input advertising space data, and the publisher wants to place an advertisement. An advertisement request input unit for inputting the media company, an advertisement request storage unit for storing the input advertisement request data, the advertisement space data and the advertisement request space data, the advertisement space data, and the advertisement request A combination processing unit that combines these data when the data matches each other and a combination output unit that outputs the combination data are provided. According to the system disclosed in Patent Document 1, although advertising frames can be exchanged among a number of media companies, the TVCM trend of other stations cannot be grasped, and the above problem cannot be solved.

Further, Patent Document 2 discloses a television text multiplex broadcast transmission method in which a TVCM in a broadcast signal distributed from a key station of the same series is replaced with the TVCM of the own station. This television text multiplex broadcast transmission system has organization data that determines the transmission order and processing for display screen data or note data stored in advance in the transmission device, and a program information designation page according to the instruction of the organization data The display screen data or the note data is replaced with the display screen data or the note data created separately. According to the method of Patent Document 2, display screen data or note data can be replaced with immediate effect, but the TVCM trend of other stations cannot be grasped, and the above problem cannot be solved.
Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a CM survey apparatus that can obtain a highly reliable and stable CM survey result of other stations at a low cost.

(1) Identifying other station CMs by judging the identity of other station CMs and past other station CMs The CM investigation device according to the present invention acquires data for acquiring other station CMs to be investigated from the CM storage and storage means. The other station CM stored in the other station CM storage unit that stores the other station CM without overlapping with the reading unit is compared with the other station CM acquired by the data reading unit to determine the identity of the other station CM. A CM collating unit to perform, and an other station CM storage unit that stores in the other station CM storage unit an other station CM determined by the CM collation unit to be the same as the other station CM of the other station CM storage unit, Information indicating that the other station CM to be processed is the same as the other station CM stored in the other station CM storage unit when the CM collating unit determines that the other station CM is the same as the other station CM in the other station CM storage unit. Is stored in the other station CM information management storage means.

  As described above, according to the present invention, the other station CM to be investigated is compared with the other station CM accumulated for identifying the CM to determine the identity, and the other station CM to be processed is identical to the other station CM to be processed. If there is a station CM, it is identified as the other station CM. If the other station CM to be processed does not have the same other station CM, the other station CM to be processed is stored for identification. There is an effect that a survey result for analysis can be obtained. By counting the information indicating the same CM, it is possible to grasp the number of broadcasts for each other station CM broadcast during the survey period.

The CM storage and storage means is a CM storage database in the embodiment described later. The CM investigation device may have CM storage and storage means.
The other station CM storage means is an other station CM database in the embodiment described later. The CM investigation device may have other station CM storage means.

  As described above, the information indicating that the other station CM to be processed is the same as the other station CM stored in the other station CM storage means is stored in the other station CM information management storage means. Therefore, instead of this, identification information indicating that the other station CM information is the same CM for the other station CM determined by the CM collating unit as the other station CM is determined to be the same as the other station CM. Then, the CM investigation device may further include an other station CM information operation unit stored in the other station CM information management storage means. Here, the identification information indicating the same CM is a duplicate CMID in the embodiment described later. For example, instead of assigning a duplicate CMID for each other station CM as in the embodiment described later, the same other station CM is stored as the same group, and the number of members of the group is the number of times of the same other station CM. In addition, the same other station CM can be connected to the same list and stored, and similarly, the number of data in the same list can be the number of times of the same other station CM.

(2) Identifying the other station CM by judging the identity of the other station CM and the past own station CM. The CM checking unit according to the present invention is configured so that the CM collation unit does not overlap the own station as necessary. The local station CM stored in the local station CM storage means for storing the CM is compared with the other station CM acquired by the data reading unit to determine the identity of the other station CM, and the CM collating unit determines the local station CM. When it is determined that the local CM of the storage unit is the same as the local CM of the storage unit, information indicating that the other station CM to be processed is the same as the local station CM of the local station CM storage unit being the same is stored in the other station CM information management storage It is memorized in the means.

As described above, according to the present invention, the other station CM to be processed is compared with the own station CM and the identity is determined and identified, so that the other station CM trend can be grasped in comparison with the own station CM. Has the effect of being able to.
The local station CM storage means is a local station CM database in the embodiment described later. The CM investigation device may have its own station CM storage means.

  In addition, when the other station CM that is the same as the own station CM is excluded, it is possible to efficiently grasp the other station CM except for the same CM as the own station CM in grasping the other station CM trend. Have. It is possible to analyze by excluding advertisers who have already requested advertisements in their own station. From the viewpoint of receiving more advertisement requests from advertisers who have already requested advertisements in the local station, it is desirable to grasp the same CM as the local station CM. Here, if the advertiser is known for the CM stored in the CM storage means, the same CM is the same advertiser. Therefore, the other station CM to be investigated is the same as the CM advertiser in the CM storage means.

(3) Automatically accumulate own station CM The CM investigation system according to the present invention stores the own station CM without overlapping with the own station CM data reading unit that acquires the own station CM from the CM accumulation and storage means. A local station CM verification unit that compares the local station CM stored in the local station CM storage unit with the local station CM acquired by the data reading unit and determines the identity of the local station CM, and the local station CM verification unit The local station CM storage device including the local station CM storage unit that stores the local station CM determined to be not the same as the local station CM in the local station CM storage unit according to (2). It consists of the described CM investigation device.
As described above, according to the present invention, not only the other station CM for identification but also the own station CM can be automatically stored.

(4) Do not output only one other station CM as a survey result The CM survey user terminal according to the present invention uses the CM survey device of any one of (1) to (3) to store other station CM information management storage means. A CM survey user terminal including a CM survey result output unit that outputs the CM information stored in the other station as a survey result, and indicates that the CM survey result output unit is the same CM among the other station CMs. The number of times for each other station CM based on the information is not output as the investigation result for the other station CM for a predetermined time or less than a predetermined number of times.

  As described above, according to the present invention, when the other station CM is broadcast only a predetermined number of times or less, the other station CM is not output as the investigation result. Therefore, the other station CM that is not a CM or the less important other station CM is excluded. Therefore, it is possible to grasp the CM trend of other stations. One reason that other-station CMs that are not CMs are read is that broadcast signals cannot be separated into programs and CMs without error.

In the embodiment described later, the other station CM whose number is 1 is not output.
The present invention grasped as a CM investigation device can be grasped as a program as will be apparent to those skilled in the art.
These outlines of the invention do not enumerate the features essential to the present invention, and a sub-combination of these features can also be an invention.

  Embodiments of the present invention will be described in detail with reference to the drawings. The present invention can be implemented in many different forms. Therefore, it should not be interpreted only by the description of this embodiment. Also, the same reference numerals are given to the same elements throughout the present embodiment.

  In the present embodiment, the system will be mainly described. However, as will be apparent to those skilled in the art, the present invention can also be implemented as a program and method usable in a computer. In addition, the present invention can be implemented in hardware, software, or software and hardware embodiments. The program can be recorded on any computer-readable medium such as a hard disk, CD-ROM, DVD-ROM, optical storage device, or magnetic storage device. Furthermore, the program can be recorded on another computer via a network.

As will be described later, since all of these components do not communicate with each other, this embodiment can be constructed by adopting a network configuration that enables operations described later. That is, the network configuration in FIG. 1 is only an example.

[1.2 Hardware]
FIG. 2 is a schematic diagram of the hardware configuration of the computer according to the present embodiment.
As shown in FIG. 2, the broadcast signal receiving apparatus 10 includes a CPU (Central Processing Unit) 101, a main memory 102, a motherboard chip set 103, a video card 104, an HDD (Hard Disk drive) 111, a bridge circuit 112, and a network interface 113. , IEEE interface 114, optical drive 121, keyboard 122 and mouse 123.

The main memory 102 is connected to the CPU 101 via the CPU bus and the motherboard chip set 103.
The video card 104 is connected to the CPU 101 via an AGB (Accelerated Graphics Port) and a motherboard chip set 103.

  The HDD 111 is connected to the CPU 101 via a PCI (Peripheral Component Interconnect) bus and the motherboard chip set 103. With a similar connection configuration, a network interface 113 and an IEEE (Institute of Electrical and Electronics Engineer) interface 114 are also connected to the CPU 101. The network interface 113 is connected to a network device (such as a hub) via a network cable. The IEEE interface 114 is connected to the TV tuner box 12 via, for example, an IEEE 1394 cable.

  The TV tuner box 12 is connected to an antenna 11 that receives radio waves of a broadcast signal via an antenna cable. The radio wave of the broadcast signal received by the antenna 11 becomes an electric signal and is sent to the TV tuner box 12 via the antenna cable. The TV tuner box 12 takes out a broadcast signal of a specific broadcasting station from the received electrical signal, converts it into a predetermined data format, and sends it to a computer that constructs the broadcast signal receiving apparatus 10 via an IEEE1394 cable to be connected. Here, the TV tuner box 12 that is externally connected to the computer is used, but a built-in TV tuner that is connected to the computer via a PCI bus can also be used. A device in which a TV tuner and an antenna are integrated can also be used. A USB connection type TV tuner can also be used.

  The optical drive 121 is connected to the CPU via a low-speed bus, a bridge circuit 112 of the low-speed bus and the PCI bus, the PCI bus, and the motherboard chip set 103. The keyboard 122 and the mouse 123 are also connected to the CPU 101 with the same connection configuration. The optical drive 121 is a drive that reads (or reads and writes) data by irradiating an optical disk with a laser beam, and corresponds to, for example, a CD-ROM drive, a DVD drive, or the like.

  Although the hardware configuration here is an explanation of the computer constructing the broadcast signal receiving device 10, the broadcast signal database 20, the CM survey device 30, the CM database server 40, and the CM survey user terminal 50 are constructed. The computer has substantially the same configuration. The IEEE interface 114 is provided so that the computer on which the broadcast signal receiving device 10 is constructed is connected to the TV tuner box 12. The broadcast signal database 20, the CM investigation device 30, the CM database server 40, and the CM The computer on which the survey user terminal 50 is constructed is not connected to the antenna 11 and the TV tuner box 12 and need not be provided.

  2 schematically shows a hardware configuration of a computer in which the broadcast signal receiving device 10, the broadcast signal database 20, the CM survey device 30, the CM database server 40, and the CM survey user terminal 50 according to the present embodiment are constructed. It is only an example shown, and various other configurations can be adopted as long as this embodiment is applicable.

[1.3 System components]
FIG. 3 is a module configuration diagram of components of the CM investigation system according to the present embodiment.
The broadcast signal receiving apparatus 10 includes an antenna (aerial) 11 that receives radio waves of a broadcast signal, and a TV tuner box 12 that extracts a broadcast signal of a specified broadcast station from broadcast signals received by the antenna 11. A program CM dividing unit 13 that divides a broadcast signal of a specific broadcasting station output from the TV tuner box 12 into a program and a CM. In the present embodiment, this broadcast signal receiving apparatus 10 is required for the broadcast station to be investigated. For example, in the case where there are three broadcast stations to be investigated, “XXX station”, “ΔΔΔ station”, and “□□□ station”, three broadcast signal receiving apparatuses 10 are required. However, since a plurality of TV tuner boxes 12 can be connected to the computer on which the broadcast signal receiving apparatus 10 is constructed, it is not necessary to prepare the number of survey target broadcast signal receiving apparatuses 10 in that case. In the present embodiment, among the constituent elements of the broadcast signal receiving apparatus 10, the antenna 11 is used in common, and a distributor that divides the input signal into a plurality of parts is used. 11 may be provided.

The antenna and TV tuner are well-known and commonly used techniques, and detailed description thereof is omitted.
The program CM dividing unit 13 also uses a known and commonly used technique for dividing a CM and a program. For example, it is possible to identify a CM and a program by detecting the silent part of the sound of the broadcast signal and starting or ending the detected silent part. When the boundary between the audio signal CM and the program is specified, the boundary between the corresponding CM on the video signal and the program can also be specified. Thereby, both the audio signal and the video signal can be divided into a CM and a program. In this embodiment, the CM audio signal and video signal and the program audio signal and video signal are acquired from the broadcast signal and stored, but at least the CM audio signal and video signal may be stored. Further, although the CM audio signal and the video signal are stored, a configuration in which the one used in the CM verification of the CM verification unit 32 described later may be stored. However, when the broadcast station staff can browse the CM together with the survey result using the CM survey user terminal 50, it is desirable to output the audio signal and video signal of the CM, and it is preferable to store both.

The broadcast signal database server 20 has a function of managing a program storage database 21 in which only programs are stored and a CM storage database 22 in which only CMs are stored. Specifically, in response to an external request for addition, update, or deletion after authentication, the corresponding operation is executed. As described above, in this embodiment, only the CM storage database 22 may be configured. The CM storage database 22 includes a broadcasting station, broadcasting date and time, CM seconds, and CM data.
The CM investigation device 30 includes a data reading unit 31, a CM collation unit 32, another station CM storage unit 33, and another station CM information operation unit 34.

  The data reading unit 31 has a function of acquiring CMs included in the designated survey period from the CM accumulation database 22. More specifically, after accessing the broadcast signal database server 20 and performing authentication, an inquiry is performed so that a CM for a designated survey target period can be acquired. The inquiry follows the inquiry language used in the database system to be used. Here, after the CM investigation apparatus 30 acquires the CM, the acquired CM may be deleted from the broadcast signal database server 20. Even if the processing CM is once acquired and deleted in the broadcast signal database server 20 in this way, the other station CM information is stored in the other station CM information management database 43, so the survey period is the survey before the previous time. Even if it overlaps with the period, other station CM information in the investigation period that does not overlap is processed to obtain other station CM information, and the other station CM information in the investigation period is combined with the other station CM information that has already been processed. It can be. This can be realized without deleting the other station CM processed from the broadcast signal database server 20 as described above when the survey period set so far is recorded. The data reading order of the data reading unit 31 may be such that other station CMs within the survey period may be read at random, but are preferably read for each broadcasting station, and are preferably read in chronological order.

  The CM collation unit 32 acquires the CM video signal stored in the local CM database 41, compares it with the CM video signal acquired by the data reading unit 31, and determines whether or not they are the same CM. When it is not the same as any of the own station CMs in the own station CM database 41, the CM video signal stored in the other station CM database 42 is acquired and compared with the CM video signal acquired by the data reading unit 31. , Has a function of determining whether or not the same CM. In the present embodiment, the CM video signal is used for the CM identity determination, but it may be an audio signal, or a video signal and an audio signal.

  As the video signal collation technique here, a well-known or commonly used technique or a known technique can be used. First, it is possible to use a collation process in which frames composing each of the CM video signal of the data reading unit 31 and the CM video signal of the CM database server 40 are collated and regarded as the same with a predetermined similarity. Second, it is possible to use one that performs image collation between the first frames at predetermined intervals. Thirdly, image collation of the first or second frame may be performed by calculating and collating feature data such as frequency conversion instead of a direct image. Fourth, similar processing can be performed on an audio signal instead of a video signal. Fifth, if both video signals and audio signals are used and either one has a predetermined similarity, or both have a predetermined similarity, the same CM should be used. You can also.

  In the present embodiment, using the third method, the feature data of the CM video signal is obtained, and the identity of the CM is obtained by comparing them. Therefore, the CM collation unit 32 calculates the feature data of the CM video signal acquired by the data reading unit 31, and obtains in advance the CM video signal stored in the local station CM database 41 or the other station CM database 42. The obtained feature data is acquired, the feature amounts are compared, the similarity is obtained, and the identity of the CM is determined based on whether or not a predetermined threshold is exceeded.

  The CM database server 40 has a function of managing the own station CM database 41, the other station CM database 42, and the other station CM information management database 43. Specifically, in response to an external request for addition, update, or deletion after authentication, the corresponding operation is executed. The own station CM database 41 includes CMID, CM data, and feature data for uniquely identifying a CM. Similar to the local station CM database 41, the other station CM database 42 also includes CMID, CM data, and feature data. Here, the own station CM database 41 preferably has a CM name and an advertiser.

  The other station CM information management database 43 includes a CMID, a duplicate CMID, the number of times (the same number of CMs in the same broadcasting station), a determination flag, a CM time, a broadcasting station, a broadcasting date and time, a CM name, an advertiser, and a CM classification.

  The duplicate CMID is the CMID of the own station or another station that is the same as the CM to be processed. By counting the same overlapping CMID of the same broadcasting station, it is possible to grasp how many times the same CM has been broadcast during the survey period. The CM data selected by the user can be viewed by reading the CM data from the local station CM database 41 or the other station CM database 42 based on the duplicate CMID of the other station CM information selected by the user and playing it back. Can do.

When the number of times is not the same as that of other CMs, an initial value of 1 is given, and the number of times is incremented by 1 in the order of the time series of the same CM. For example, when a certain CM is broadcast and processed, an initial value of 1 is assigned to the number of times, and when the same CM is broadcast and processed thereafter, 2 incremented by 1 is assigned. A value incremented by 1 is assigned for each subsequent broadcast.
The determination flag is a flag that rises when the number of times is an initial value of 1.

  When the CM name and the advertiser are the same as the CM in the other station CM database 42, the CM name and the advertiser of the other station CM information related to the same CM are used. When the own station CM database 41 has a CM name and an advertiser, if it is the same as the CM in the own station CM database 41, the CM name and the advertiser of the same CM Become.

The CM classification includes values of “unconfirmed”, “not subject”, “net CM”, and “survey target”. “Unconfirmed” is a category value for which the CM category has not been confirmed. “Excluded” is a segment value assigned to a program recognized as a CM, a program PR recognized as a CM, or a program that was not a CM. “Net CM” is a segment value given to a CM inserted by a key station. “Survey object” is a division value given to a CM to be investigated in the CM research. Only CMs to which this “survey target” CM classification value is assigned become the target of the CM survey. The initial value is “unconfirmed”, and when the same as the CM in the local station CM database 41 or the other station CM database 42, “investigation target” is given. This CM classification can be changed by the user using the CM survey user terminal 50. In addition,
The other station CM storage unit 33 has a function of storing, in the other station CM database 42, a new CM in which no CM is stored in either the own station CM database 41 or the other station CM database 42 in the CM collation unit 32.
The other station CM information operation unit 34 has a function of adding the CM information for the one CM to the other station CM information management database according to the collation result of the CM collation unit 32 for one CM.

  The CM survey user terminal 50 includes a CM survey setting unit 51 and a CM survey result output unit 52. The CM survey setting unit 51 has a function of accepting CM survey settings from the user and performing the accepted settings. Specifically, the CM survey setting unit 51 sends the received settings to the CM survey device 30. The CM investigation device 30 receives the CM investigation setting and executes the CM investigation. The item of CM survey setting is mainly the survey period. The survey period consists of the survey start date and time and the survey end date and time. The CM survey result output unit 52 has a function of acquiring and outputting a CM survey result processed by the CM survey device 30. Specifically, the CM survey result output unit 52 is configured to read and acquire the CM survey result processed by the CM survey device 30 from the other station CM information management database 43 according to the designated CM survey setting. The CM survey device 30 may add the other station CM information to the other station CM information management database 43 and store it in the temporary storage area and return it to the CM survey user terminal 50.

  The CM survey result output unit 52 is configured not to output a CM for which a determination flag is set, that is, a CM that is counted once in the same broadcasting station during the survey period. A CM whose number of times is only one is not read from the CM information management database 43. Here, it is possible to adopt a configuration in which a CM whose number of times is only one is read from the CM information management database 43 but is not output.

[2. Operation]
Since the processing until the programs and CMs are collected by each broadcast signal receiving apparatus 10 and stored in the broadcast signal database server 20 is clear, description thereof will be omitted.
[2.1 Addition of data in own CM database]
As for the CM of the own station, CM data consisting of video signals and audio signals can be acquired from CM bank devices and various sales systems. Similar to the processing of the CM collation unit 32, the feature data of the CM video signal is calculated from the acquired CM data video signal. CM data for each CM and the calculated feature data of the CM are added to the local CM database.

  For example, the user takes in the CM data of the local station onto the CM research user terminal 50 using a network or an external storage medium, and uses a feature data calculation unit that calculates the feature data of the video signal from the video signal. The feature data of the CM video signal is calculated from the CM data video signal, and the calculated feature data and the original CM data are added to the local CM database 41. In order to realize this specifically, the local station CM database operation unit for adding a combination of feature data and CM data to the local station CM database 41 and the local station CM import function including the feature data calculation unit are used for CM investigation. To the user terminal 50. Of course, the local station CM import function may be mounted on another computer, or only the feature data calculation unit is mounted, and the local station CM database operation unit generally uses a query language provided by the database development company. It may be added using a database client. Along with the addition of this CM, a CM name and an advertiser may be added to each CM.

[2.2 CM survey operation]
FIG. 4 is a flowchart of the CM investigation operation of the CM investigation system according to this embodiment. FIG. 5 is an example of a GUI in the CM research user terminal according to the present embodiment.
After the CM survey user terminal 50 is activated and authenticated, when the “new survey setting” in FIG. 5A is pressed from the top screen of FIG. 5 (not shown), the survey period and memo are displayed in a configurable manner. A setting window (not shown) is displayed. For example, for the CM survey user terminal 50, the user sets the survey start date and time of the survey period to “2006/04/01 (09:00:00)” and the survey end date and time to “2006/04/07 (08 : 59: 59) ".

The CM survey setting unit 51 of the CM survey user terminal 50 receives the survey period. The accepted survey period is sent to the CM survey device 30.
The CM survey device 30 captures the survey period accepted from the user, and the data reading unit 31 acquires the CM video signal included in the retrieved survey period from the CM storage database 22 (step S200). If the other-station CM information has already been obtained and stored in the other-station CM information management database 43, the subsequent processing may not be performed for the obtained investigation period.

  The CM survey collating unit 32 determines whether there is a CM video signal that has not been processed in the CM video signal within the survey period captured by the data reading unit 31 (step S205). If so, the process is terminated.

  When it is determined in step S205 that there is an unprocessed CM video signal, the CM collation unit 32 calculates feature data of the CM signal to be processed and reads it from the local CM database 41 at least up to this point. It is compared with the feature data of the video signal of the CM (step S210), and it is determined whether there is a local CM that is identical to the one CM (step S215). The comparison here is for the feature data of the video signals of all the local CMs in the local CM database 41.

  When the CM collation unit 32 determines that the local station CM is the same as the local station CM, the other station CM information operation unit 34 acquires the local station CM information (step S240), and acquires the CM name of the acquired local station CM and the advertiser. CM section and CMID are added to the other station CM information management database 43 as CM information (each CM name, advertiser, CM section “survey target”, duplicate CMID) regarding the CM to be processed. Other attributes of the other station CM information management data 43 are obvious from the attributes of the CM to be processed, such as CMID, CM time, broadcast station, and broadcast date and time, and values thereof are added. Further, the remaining number of attributes and the determination flag are added as follows. As the number of times, a number obtained by adding 1 to the total number of other CMs having the same overlapping CMID in the same survey period in the same broadcasting station is added. The determination flag is 0 if the number of additions is 2 or more, and 1 if it is 1. The process of adding to the other station CM information management database 43 by the other station CM information operation unit 34 for the CM to be processed after step S240 is step S235.

  If it is determined in step S215 that the processing target CM is not the same as the local station CM, the calculated feature data of the processing target CM is read from the other station CM database at least up to this point in time as a video signal of the CM. (Step S220), it is determined whether there is another station CM that is the same as the CM (step S225). When the CM collation unit 32 determines that the CM is the same as that of the other station CM, the CM information of the CM of the other station, the advertiser, the CM classification, and the CMID are the CM information about the CM to be processed (CM name, advertiser, CM section “survey target”, duplicate CMID) is added to the other station CM information management database 43. Other attributes of the other station CM information management data 43 are obvious from the attributes of the CM to be processed, such as CMID, CM time, broadcast station, and broadcast date and time, and values thereof are added. Further, the remaining number of attributes and the determination flag are added as follows. As the number of times, a number obtained by adding 1 to the total number of other CMs having the same overlapping CMID in the same survey period in the same broadcasting station is added. The determination flag is 0 if the number of additions is 2 or more, and 1 if it is 1. The additional process of the other station CM information management database 43 by the other station CM information operation unit 34 for the CM to be processed after step S225 is step S235.

If the CM collation unit 32 determines in step S225 that the CM is not the same as the other station CM, the CM ID, CM data, and feature data of the CM to be processed are added to the other station CM database 42 (step S230). Since the CM name, advertiser, and CM classification for one CM are new CMs, there is no value, so “Null” or “No value” (only the CM classification is “unconfirmed”), the other station CM information management database 43 Add to The CMID, CM time, broadcast station, and broadcast date and time are clear from the attributes of one CM that is a processing target, and the CMID of one CM may be used as a duplicate CMID to which the value is added. Further, the number of remaining attributes is “1”, the determination flag is 1 and the flag is set. The process of adding the other station CM information management database 43 by the other station CM information operation unit 34 for the CM to be processed after step S230 is step S235.
After step S235, the process returns to step 200.

When the user presses the “unconfirmed CM maintenance” in FIG. 5B of the CM user terminal 50 after the process is completed, the CM survey result output unit 52 searches the survey results of the survey period from the other station CM information management database 43. Is obtained and output, as shown in FIG.
The total of the survey results is shown in the center of the window of FIG.

  The total of survey results is composed of fields of survey period / memo, total number of CMs, station CM, person in charge, and status. The memo is input by the user set as necessary when setting the survey period. The total number of CMs consists of the total number of CMs in the target broadcast station during the survey period, and unconfirmed and confirmed according to the CM classification. Confirmation is when the CM segment value is “not applicable”, “net CM”, or “survey target”. The field of the total CM number field by broadcast station is the field of station CM. The person in charge is the user who set the survey. The situation consists of “confirmed” and “unconfirmed”. If there is at least one unconfirmed CM, it becomes “unconfirmed” and becomes “confirmed” when all CMs are confirmed.

  The CM category list box at the top of the details of the survey result displays the details of the CM corresponding to the selected CM category in the lower list. By pressing the “Redisplay” button with the image display check box checked, several thumbnails of CMs in the lower list are displayed and redrawn. Conversely, by depressing the “redisplay” button without checking the image display check box, the CM thumbnails in the lower list disappear and redraw. The “Change CM section” button collectively changes the CM section to the CM section value that can be specified in another window for the CM whose check box in the rightmost “CK” field in the list is valid. It is a button for. Of the fields in the lower list, “second” is equal to the CM time, and “broadcast date / time” is the broadcast date / time of the CM with the frequency of 1 (this represents the oldest broadcast date / time on behalf of the same CM) However, it may be the latest broadcast date and time), and the “number” is equal to the maximum number of duplicate CMIDs. When the “Display” button in the “Preview” field is pressed, the CM data of the corresponding CM is read from the local station CM database 41 and the other station CM database 42 based on the duplicate CMID, and the video signal of the CM data is displayed in a separate window. And the audio signal is played back.

  Here, although the window of FIG. 5 is displayed by the CM survey result output unit 52, the CM of the number of times and the CM with the determination flag set are not displayed in the lower list. With this configuration, it is possible to efficiently analyze other-station CM trends by excluding those that are not CMs, or even CMs that have few advertising spaces. Here, it is desirable that a determination flag is set for a CM that is a one-time CM and the CM category is “unconfirmed” to be excluded from an output target instead of a one-time CM.

  When the CMID of each CM in the lower list of the window of FIG. 5 is pressed, another window is displayed, and the CM name, advertiser, etc. in the list can be input. The input value is updated for the corresponding CM on the other station CM information management database 43.

(Other embodiments)
[Automatic storage of own station CM]
In the first embodiment, the local station CM and the feature data stored in the local station CM database are explained to be prepared in advance by the user. However, the local station CM storage device 60 is newly provided, Also, it is possible to provide a broadcast signal receiving apparatus 10 for the own station, take in the own station CM via the broadcast signal database 20, and add a new own station CM to the own station CM database 41. FIG. 6 is a module configuration diagram of components of the CM investigation system according to the present embodiment. However, for convenience of illustration, only the module configuration related to the local station CM accumulation is shown.

The local station CM storage device 60 includes a local station CM data reading unit 61, a local station CM verification unit 62, and a local station CM storage unit 63.
The local station CM data reading unit 61 reads a local station CM that has not been read from among the CMs stored in the CM database 22 of the broadcast signal database server 20. Here, after the local station CM data reading unit 61 reads the local station CM, the read local station CM may be deleted from the broadcast signal database server 20.

  As described in the first embodiment, the local station CM collation unit 62 calculates feature data of the read CM video signal, and stores at least the CM feature data stored in the local station CM database 41. It has a function of reading and comparing up to a time point and determining whether or not they are the same based on the similarity.

  When the same CM is already stored in the own station CM database 41 based on the collation result of the own station CM collation unit 62, the own station CM storage unit 63 does not add the CM to be processed, When the same CM is not yet stored in the own station CM database 41, it has a function of adding a CM to be processed. Although the CM ID, CM data, and feature data are automatically stored in the own station CM database 41, the CM name, advertiser, and CM classification are not automatically stored. The name, advertiser, and CM classification may be updated.

[Not subject to investigation of same CM as own station CM]
In the first embodiment, the CM classification is “investigation target” even in the other station CM that is the same as the local station CM.
Furthermore, in the first embodiment, the local station CM information is acquired (step S240) and the CM allocation process (step S235) is executed even if the local station CM is the same as the local station CM. When it is determined that the other station CM is the same as the own station CM, it is also possible to shift to step S200 and perform the next other station CM processing.

  By handling the other station CM that is the same as the own station CM in this way, it is possible to avoid an extra analysis for an advertiser common to the other station. However, even the same sponsor may operate so as to take more advertising space, and it is desirable that the function is turned on / off as an optional function according to the user's settings.
