BACKGROUND OF THE INVENTION The present invention relates to a commercial message (C) broadcast for each channel in each TV broadcasting area.
M) for automatically identifying and recording.

[0002]

2. Description of the Related Art In Japan, there are several TV broadcasting areas such as the Kanto area, the Kansai area, and the Nagoya area. Further, there are many broadcasting stations in each TV broadcasting area, and an extremely large number of CMs are broadcast every day. ing.

[0003] In such a CM for TV broadcasting, the broadcasting date and time, the number of seconds of broadcasting, etc. are decided in advance according to the contract between the broadcasting station and the sponsor, and the CM is broadcast according to a predetermined schedule. However, due to various factors, the actual broadcasting is not always performed according to the schedule. So, for each broadcasting area and each station,
It is necessary to work to confirm what CM was actually broadcast.

[0004] Conventionally, this kind of work is carried out only manually, and V offices corresponding to each station are set up at the sales offices in each broadcasting area.
A TR (video tape recorder) and a monitor TV are arranged, and some operators watch the monitor TV and CM
Make a note after confirming the content each time
This was later totaled.

However, such a method requires a lot of manpower, and since it is a human confirmation work, a confirmation error is likely to occur and there is a problem in accuracy.

In view of such circumstances, the applicant of the present invention has found that the CM automatic confirmation device as disclosed in Japanese Patent Application Laid-Open No. 3-289829, that is, the received sound of TV broadcast is silent and the video signal is greatly reduced. When the change occurs, it is judged as the start or end of the CM, the audio signal during that time is extracted, and compared with the audio signal stored in advance.
We have previously proposed a device for automatic identification.

[0007]

By using the above-mentioned proposed automatic CM checking apparatus, it is possible to mechanize the CM checking work, and labor saving and high reliability are achieved. There are still some problems to be solved in applying the device technology to the actual field.

[0008] One of them is that, in the above-mentioned proposed automatic CM confirmation apparatus, the CM extraction means (CM data collation computer) carries out the CM confirmation by collating the voice data. When performing CM identification for each broadcasting station, it is necessary to store the reference voice data in each CM data collating computer, which complicates the management of the reference data, and also the voice data comparison and collation function. Is necessary for each station.

Therefore, the first object of the present invention is to collectively manage the reference voice data and the comparison and collation using the same in a single CM identification device common to a plurality of broadcast areas. CM that manages reference data easily and does not require a comparison and verification function for voice data for each station
To provide an automatic identification system.

Another one of the problems to be solved is a problem regarding a new material CM in which the reference voice data is not yet registered. That is, since the standard audio data is not registered for the new material CM, it is not subject to automatic identification. Therefore, manual work is necessary, but
As described in the above-mentioned Japanese Patent Laid-Open No. 3-289829, all broadcast contents are recorded on a VTR for each station, and CMs that could not be automatically identified are identified while playing them back. According to the method, it takes time and effort to confirm the new material CM, and it becomes difficult to identify the new material CM promptly.

Therefore, a second object of the present invention is to enable automatic identification of CMs already being broadcast in other stations even if they are new material CMs in that station.

A third object of the present invention is to enable quick manual confirmation of a complete new material CM, and to automate registration of audio data as a reference for the new material CM. And then appear the same C
It is to enable automatic identification for M.

The main operation of the above embodiment will be described below with reference to specific configuration examples of each section.

(1) Extraction of CM audio data by CM extraction device CM extraction device 1-1 in each TV broadcasting area (1)-(3)
Each of CM scanners 10-1 and the like in 1-3 receives TV broadcasts from the stations that the scanner owns among TV broadcasts broadcast in the TV broadcast area, detects CM audio data, and In the case of the embodiment, the CM extraction control device 1 outputs the CM data including the detected CM audio data, the start time at which the CM audio data appears, the number of seconds of the CM, and the station name.
Propagate to 3. Also, the video signal VI of the broadcast being received
And the audio signal AU and the time signal T are transmitted to the video / audio memory device 11-1 corresponding to itself.

FIG. 2 is a block diagram showing a configuration example of the CM scanner 10-1, and other CM scanners 10-n and the like have the same configuration. This CM scanner 10-1 is
Reception circuit 100, synchronization separation circuit 101, stereo signal detection circuit 102, audio data creation unit 103, audio silence detection unit 104, video change detection unit 105, clock unit 106, superimpose circuit 107, and control unit (CPU board) 108. It consists of

In the CM scanner 10-1 of FIG. 2, among the broadcast waves arriving at the receiving antenna, the broadcast wave of the station (station A) which the scanner itself is responsible for is received by the receiving circuit 100 and is the audio signal AU and the composite signal. Video signal V
I is taken out. The video signal VI output from the receiving circuit 100 is input to the sync separation circuit 101, a vertical sync signal V and a horizontal sync signal H are generated, and are supplied to each unit. On the other hand, the audio signal AU output from the receiving circuit 100
Is input to the stereo signal detection circuit 102, it is determined whether or not it is stereo broadcasting by the presence or absence of the identification signal, and if it is stereo broadcasting, a signal to that effect is given to the control unit 108.
Etc.

The audio signal that has passed through the stereo signal detection circuit 102 is input to the audio data creation unit 103, and the audio data creation unit 103 uses the vertical sync signal V provided from the sync separation circuit 101 as a sampling timing to output a predetermined bit. Create digitized voice data.
The created voice data is taken into the control unit 108 and stored in the RAM or the like. Also, the voice data creation unit 10
The voice signal branched from 3 is input to the voice silence detector 104, and the voice silence detector 104 receives the sync separation circuit 10
By sampling the vertical synchronization signal V given from 1 as the reference timing, the silence data of a predetermined bit indicating whether or not there is a silence state is created and sent to the control unit 108.

On the other hand, the video signal VI output from the receiving circuit 100 is also input to the video change detecting unit 105 and the superimposing circuit 107, and the video change detecting unit 1
Reference numeral 05 samples the video signal with the vertical sync signal V and the horizontal sync signal H provided from the sync separation circuit 101 as sampling timings, and the video signal changes abruptly and drastically based on the degree of difference between the sampling values of the preceding and following frames. Whether or not it has occurred is detected, and if such a change has occurred, a signal indicating that effect is given to the control unit 108. Note that the stereo signal detection result is input from the stereo signal detection circuit 102 to the video change detection unit 105 because CM is often performed in stereo broadcasting, and therefore video change detection is performed depending on whether stereo broadcasting is performed or not. This is because the determination standard of the unit 105 is changed.

The control unit 108 constantly monitors the silence data from the voice silence detector 104, and when the data indicating the silence state continues for, for example, 250 ms, determines that the silence state has occurred, and at that time point. In the case where the video change detection unit 105 detects the switching of the screen in, it is determined that the CM starts or ends. Then, the current time at that time is read from the clock unit 106 and held internally, and the CM time is measured by an internal soft timer, and C
10 seconds, 15 seconds, 3 which are commonly used as M time
If it ends in 0 seconds, CM with it
Is determined to be the end time point, and the measured CM time is traced back from that time point, and the audio data created by the audio data creation unit 103 during that time is read from the internal RAM. This means that the CM voice data can be detected.

When the control section 108 detects the CM voice data, the control section 108 detects the detected CM voice data, its start time, and C
The CM data including the number of M seconds and the station name (station A) that it is in charge of is created and sent to the CM extraction control device 13.

The control unit 108 also converts the time signal indicating the current date and time output from the clock unit 106 into character information and supplies it to the superimposing circuit 107.
The superimposing circuit 107 adds characters such as date and time to the video signal VI from the receiving circuit 100 and outputs it to the video / audio memory device 11-1. The output of the clock unit 106 is also output as the time signal T to the video / audio memory device 11-1.

The CM extraction control device 13 has a one-to-one correspondence with the CM scanners 10-1 to 10-n as shown in FIG. 3, for example.
Scanner interface 130-1 to 1 corresponding to
30-n and each of the video / audio memory devices 11-1 to 11-n
And audio / video memory device interfaces 131-1 to 131-n corresponding to each other and VTR 12 for each new material CM
VTR for new material CM that corresponds to -1 to 12-n one to one
Interfaces 132-1 to 132-n and the CPU 13
3, a ROM 134, a RAM 135, an online interface 136, and a bus 137 connecting them, and the online interface 136 is connected to the modem 14 in FIG.

When the CPU 133 receives CM data from the CM scanners 10-1 to 10-n in FIG. 1 through the CPU scanner interfaces 130-1 to 130-n, the received CM data is transferred to the online interface 1
36, C through the modem 14 and the communication path L11 in FIG.
It is sent to the M identification device 3. At this time, multiple CMs are simultaneously
RAM1 when CM data is received from the scanner
In 35, buffering is performed and 1 CM data is sequentially sent to the CM identifying device 3.

Operations similar to those of the CM extraction device 1-1 as described above are simultaneously performed in the CM extraction devices 1-2 and 1-3 provided in the other TV broadcasting areas (2) and (3). Has been done in.

(2) CM Identification by CM Identification Device 3 In FIG. 1, CM reference data files 312-1 to 312-3
The CM reference data 12-m stores CM reference data to be used in each broadcasting area. At least before the CM identification start time on the day of CM identification, the CM reference data file 312 is stored.
CM reference data to be used on the relevant CM identification date among -1 to 312-m is the network server 306 and L.
C of CM comparison computer 307 through AN300
M reference data memory 314-1, 314-2, 314
Loaded in 3. Here, the CM reference data memory 31
CM reference data corresponding to the TV broadcast area (1) is stored in 4-1, CM reference data corresponding to the TV broadcast area (2) is stored in the CM reference data memory 314-2, and CM reference data memory 314-3 is stored in the CM reference data memory 314-3. Is loaded with CM reference data corresponding to the TV broadcasting area (3).

FIG. 4 shows an example of the contents of the CM reference data loaded in the CM reference data memory 314-1, and the CM reference data loaded in the other memories 314-2 and 314-3 have substantially the same structure. It has become.

The CM code in FIG. 4 is a code for uniquely identifying a CM broadcast in all TV broadcasting areas, and is one of two types of code called a VR code and a Z code. Is used.

The VR code is a code assigned to a confirmed CM, and includes, for example, business type, maker name, product name,
The material, classification, and CM seconds are each coded and expressed as a concatenated value.

On the other hand, the Z code is a code that is automatically numbered in the CM identifying device 3 to identify the unidentified CM when the unidentified CM is identified. Below, the identified year, month, day, hour,
Minutes, seconds, broadcasted TV broadcasting area, station name, and CM seconds are each coded and expressed as a concatenated value.

Further, in the TV broadcasting area (1) shown in FIG. 4, the comparative audio data (for A station), the comparative audio data (for B station), ..., The comparative audio data (for F station) are TV.
It is comparison voice data for each CM identification target station in the broadcast area (1), and in the figure, the portion marked with "Yes" at the intersection with the line of the CM code is the actual comparison voice data recorded. That is, it means that the comparative voice data is not recorded in the portion marked with “None”. Also,
The comparison audio data (all stations) in the TV broadcasting area (2) is T
The comparison voice data of all CM identification target stations in the V broadcast area (2) and the comparison voice data (all stations) of the TV broadcast area (3) are comparison voices of all CM identification target stations in the TV broadcast area (3). Data are shown respectively, "Yes" and "No"
Has the same meaning as above. That is, in the CM reference data corresponding to the TV method area (1), the comparative voice data is independently recorded for the CM identification target stations included in the TV broadcasting area (1), and the other TV broadcasting is performed. Areas (2) and (3) are recorded without distinction between stations.

The comments and the like in FIG. 4 are information in which characters such as words and music entering the CM first, talents appearing in the CM, product names, backgrounds, etc. are recorded in characters. Therefore, this comment or the like is recorded only for the confirmed CM whose CM code is the VR code. Since comments and the like are not used directly for comparison and collation, it is not always necessary to load them in the CM reference data memory 314-1.

On the other hand, in FIG. 1, CM recording file 3
13-1 to 313-x are TV broadcasting areas (1) to
It is a file prepared for each CM identification target station of (3). In the CM recording files 313-1 to 313-x, CMs automatically broadcast and identified by the corresponding stations are identified.
All CM information for the current day of CM identification is recorded.
Individual CM information includes CM code, broadcast time, CM seconds,
Contains comments, etc.

The CM identifying operation in the CM identifying apparatus 3 is performed as follows.

The CM data sent from the CM extraction devices 1-1 to 1-3 in each of the TV broadcasting areas (1) to (3) is received by the CM comparison computer 307 via the modems 302 to 304 and the LAN 300. It

Upon receiving the CM data, the CM comparison computer 307 performs the following processing.

(A) Select the CM reference data memory corresponding to the TV broadcast area to which the CM extraction device that has sent out the CM data belongs. Now, the CM reference data memory 314-
It is assumed that 1 is selected.

(B) Selected CM reference data memory 31
Received CM in the section of comparative voice data in 4-1
Pay attention to the column of comparative voice data corresponding to the station name in the data. For example, in the case of CM data about a CM broadcast at station A, pay attention to the column of comparative audio data (for station A) in FIG.

(C) Of the comparative voice data included in the currently focused column, the number of seconds in the CM code is the received C
The voice data for comparison that matches the number of seconds in the M data is selected and sequentially compared with the voice data in the CM data.

(D) When there is comparison voice data that matches the voice data in the CM data, the CM recording file (for example, 313-1 and the like) corresponding to the station name in the CM data received through the network server 306. To)
The CM code, comment, and the like added to the matched comparison voice data and the CM start time in the received CM data are recorded as 1 CM information, and the process for the received CM data is completed.

(E) If there is no matching comparison audio data in the processing (c), pay attention to the comparison audio data column for other stations in the same TV broadcasting area (1), and execute the processing (c). To execute. If there is no matching comparison audio data even if attention is paid to the comparison audio data fields for all other stations, the comparison audio data fields of the other TV broadcast areas (2) and (3) Attention is paid to and the process (c) is executed.

(F) In the execution of the process (c) for the column focused on by the process (e), when a matching comparison voice data is found, it corresponds to the station name in the CM data received through the network server 306. In the CM recording file, the CM code, comment, etc. added to the matched comparison voice data and the CM start time in the received CM data are recorded as 1 CM information. Furthermore, the received CM of the CM reference data memory 314-1
In the comparative voice data column corresponding to the station name in the data, the comparative voice data at a portion intersecting with the CM code of the matching comparative voice data is created from the CM voice data in the received CM data. Record the audio data for comparison. Note that it is possible to copy the above-described matched comparison voice data of other stations, but even if the same CM is used, there are subtle differences between the stations, so the CM voice data in the received CM data is used for comparison. It is desirable to create audio data.

(G) When there is no match in the comparison voice data of all the columns in the CM reference data memory 314-1 focused on by the process (e), the received CM data is a completely new material. It is determined that the data is for CM, and the following processing is performed.

(G-1) Numbering the Z code and creating comparative voice data from the CM voice data in the received CM data, and using this created comparative voice data as the station name in the received CM data. The corresponding reference voice data is added to the CM reference data memory 314-1 and the Z code assigned the number is also added. The comparison voice data added in this way will be used as comparison voice data at the time of comparison thereafter.

(G-2) Through the network server 306, in the CM recording file corresponding to the station name in the received CM data, the Z code assigned above and the received CM
The CM start time in the data is recorded as 1 CM information.

(G-3) A message including the Z-code numbered above, the station name in the received CM data, the CM start time, and the CM seconds is created, and the CM data is sent through the LAN 300, the modem 302 and the communication path L11. It is transmitted to the CM extraction device 1-1 of the transmission source. This is for recording the new material CM as described later. The CM extracting device 1-1 side temporarily stores the CM data sent to the CM identifying device 3, and the CM identifying device 3 specifies the CM data relating to the new material CM in place of the message. The message may be sent to the CM extraction device side.

(3) Recording of new material CM The video / audio memory device 11-1 of the CM extraction device 1-1,
For example, as shown in FIG. 5, an A / D converter 110 for converting the video signal VI of the station A which is constantly output from the CM scanner 10-1 into a digital video signal, and one frame of the obtained digital video signal. A data compressor 111 that performs data compression by sampling a digital video signal, for example, every one second, a video memory unit 112 that stores the data-compressed digital video signal, and a digital video read from the video memory unit 112. A D / A converter 113 for converting the signal into an analog signal and outputting it to the video signal terminal of the VTR 12-1 for new material CM;
Audio signal A of station A constantly output from the scanner 10-1
A / D converter for converting U into digital audio signal 1
14 and the obtained digital audio signal to, for example, 4 KHz
A data compressor 115 that compresses data by sampling in a cycle of about a degree, a voice memory unit 116 that stores the data-compressed digital voice signal, and a digital voice signal read from the voice memory unit 116 to an analog signal. Then, based on the D / A converter 117 which outputs to the audio input terminal of the VTR 12-1 for the new material CM and the time signal T output from the CM scanner 10-1, the video memory unit 112 and the audio memory unit 116 are written. The memory unit controller 118 outputs an address and a read address to control the writing and reading, and outputs a delay time signal TD to the CM extraction controller 13.

The video memory unit 112 is composed of three video memories 112-1, 112-2 and 112-3. Each of the video memories 112-1 to 112-3 has a capacity capable of recording the digital video signal output from the data compressor 111 for 60 seconds in terms of time. Therefore, three video signals can be recorded for 180 seconds.

The voice memory unit 116 is composed of three voice memories 116-1, 116-2 and 116-3. Each of the audio memories 116-1 to 116-3 has a capacity capable of recording the digital audio signal output from the data compressor 115 for 60 seconds in terms of time. Therefore, three video signals can be recorded for 180 seconds.

The memory unit controller 118 is shown in FIG.
The reading and writing of the video memory unit 112 and the audio memory unit 116 are controlled at the timing shown in FIG.
That is, regarding writing, first, the video memory 112-
1 and the audio memory 116-1 are written with the digital video signal and the digital audio signal for 60 seconds, the next 60 seconds are written in the video memory 112-2 and the audio memory 116-2, and the next 60 seconds are the video. Writing is performed in the memory 112-3 and the voice memory 116-3. Then, the operation returns to the writing in the video memory 112-1 and the audio memory 116-1 again, and the above-described operation is repeated.

On the other hand, regarding reading, each of the video memories 112-1 to 112-3 and each of the audio memories 116-1.
Control is performed to read the signals written in to 116-3 with a delay of 100 seconds.

Therefore, the relationship between the input video / audio and the output video / audio of the video memory unit 112 and the audio memory unit 116 is as shown in FIG. 6 (b).
It is output with a delay of 0 seconds. Memory unit control device 1
The delay time signal TD output from 18 represents a time delayed by 100 seconds from the current time. In other words, at what time the video and audio read from the video memory unit 112 and the audio memory unit 116 were broadcast,
This is a signal to notify the CM extraction control device 13.

[0074]

According to the CM automatic identification system of the present invention described above, the following effects can be obtained.

CM by the CM scanner for each CM identification target station in the CM extraction device provided for each TV broadcasting area
The voice data is detected, and the CM voice data and the CM data including the broadcasting station name and the time when the CM is broadcast are transmitted to the CM identifying device through the communication path, and the CM identifying device compares and collates with the comparative voice data. Since the CM is identified by the CM reference data, the CM reference data including the voice data for comparison needs to be stored in the CM identification device side. Therefore, the updating can be performed at one place, so that the reference data can be easily managed. In other words, since the comparison and collation are also intensively performed by the comparison means in the CM identification device, it is not necessary to have a voice data comparison and collation function for each station.

When the CM audio data in the CM data is not compared with the comparative audio data in the CM reference data corresponding to the station on which the CM was broadcast, the CM reference data in the other stations are not compared. Since the comparison and collation are performed with the comparison voice data, it is possible to automatically identify the CM already registered in any station. Also,
At this time, new comparison voice data is generated from the CM voice data in the received CM data, and is added to the CM reference data file as the comparison voice data in the CM reference data corresponding to the station name in the CM data. Since this is done, the automatic identification of the CM can be performed thereafter without depending on the comparative voice data of other stations.

Since the VTR for the new material CM records only the CM relating to the new material that could not be identified as a result of the comparison and collation by the CM identification device, the manual confirmation work for the new material CM should be performed quickly. You can Further, since the audio data which is the reference for the new material CM is automatically registered, the same CM that appears thereafter can be automatically identified.
