Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a television commercial broadcast confirmation device.

(Problems addressed by the prior art and the invention) Since a large number of people are involved in the operation of a television station, the content is not necessarily broadcast as planned. In particular, for TV commercials, etc., the broadcast time is scheduled in advance, but the TV commercial may not actually be broadcast at that time, and in such cases, it may be difficult for the sponsor to do so. This is a serious problem because the objectives of the period are not achieved.

For this reason, there is a task of checking whether a predetermined television commercial has been broadcast at a predetermined time for each broadcast area and predetermined channel.

By the way, the current situation is that this work has traditionally been carried out exclusively by human eyes and ears, which requires a lot of human effort, and because it is a human task, confirmation errors occur, and the reliability is not very high. There was a drawback that there was no

In addition, as a method for automatically performing i-authentication, it is possible to
Attempts have been made to insert a signal into a commercial and detect and identify the signal upon reception (for example, by inserting the signal into the blanking of the video), but there are restrictions on the signals that can be inserted due to regulations under the Radio Law. be done.

■Preliminary work is difficult.

■Lack of reliability as it does not directly check video and audio.

It was not put into practical use for several reasons.

(Means for Solving the Problems) The present invention has been proposed in view of the above points, and its purpose is to automatically check the broadcast of TV commercials and to provide highly reliable results. An object of the present invention is to provide a television/commercial broadcast confirmation device that can obtain the following information.

In order to achieve the above object, the present invention converts a plurality of TV commercials into patterns and MLMs them as data in advance, and then converts the currently received TV commercials into patterns using a data processing unit to combine them with the accumulated data. The gist is a TV/commercial broadcast confirmation device that is characterized by comparing and determining the content of TV commercials.

(Example) The present invention will now be described in detail with reference to the drawings showing embodiments.

FIG. 1 is a block diagram showing an embodiment of the television/commercial broadcast confirmation device of the present invention, which is a television TV and a video tape recorder VTR.

The antenna person NT is enabled to receive and record television broadcasts, and the switch SW selects and supplies signals from the television TV and the video tape recorder VTR to the data processing unit 100, and outputs the data processing unit 100. is provided to the sub-computer 300 via the interface 200. Note that the data processing unit 100 has a function of patterning input audio signals and video signals.

On the other hand, if the above system is assumed to be station A, the sub-computers 300 of stations B to N, which have similar configurations and are located in each broadcasting area, connect to the host computer via lines such as telephone lines.
Data is collected in the computer 400, confirmation results are checked and supervised, and reports 500 and the like are created. The mask that serves as the standard for comparison must be created for each station (TV TV, video tape recorder VTR, antenna person NT, data processing unit 100, interface 200.sub, computer 300) as described later. However, it is also possible to provide master creation data to the host computer 400 and control and manage master creation and updating all at once.

Therefore, create and update the master for each station as follows.

■Put the desired TV commercial on the video tape recorder VTR.

■ Switch the switch Sw to the video tape recorder VTR side, and send the audio signal and video signal of the TV commercial to the data processing unit 100 and convert it into a pattern.
Create data.

(2) The output signal of the data processing unit 100 is read by the sub-computer 300 via the interface 200 and accumulated (stored) in the internal memory. In addition, in order to make efficient comparisons, the master starts and ends the audio signal.
Sort by data value.

Further, the confirmation operation is performed as follows.

■Switch the switch SW to the TV side, and the data processing unit 100 converts the broadcast received at the present time into a pattern.

(2) The output signal of the data processing unit 100 is read and monitored by the sub-computer 300 via the interface 200, and when a silent period lasts, for example, one second or more, comparison with the stored master is started.

(2) In the comparison, first, the head data of the audio signal is compared with the approximate value master.

- Compare in this state for 2 seconds, and if they match, continue the comparison; if not, compare in the same way as the next master.

■If the audio signal and video signal match for the entire number of seconds (the number of seconds of the master), the result (registration code of that master, time of broadcast, etc.) is output, and if they do not match, the corresponding master Outputs the result that it was not found.

Next, FIG. 2 shows the data processing unit 100 in FIG.
There are 7 diagrams showing specific configuration diagrams.

In the figure, the audio signal SA is applied to one input terminal of the comparator @$104 by sequentially passing through the audio amplification circuit 101 and the low-pass filter 102, and the other input terminal of the comparator circuit $104 is supplied from the reference voltage generation circuit 103. A reference voltage is applied, and the output signal of the comparison circuit 19104 is applied to the counter 105 for counting. On the other hand, video signal S
V is the synchronous separation circuit 107. The comparison @
! The other input terminal of $113 is a reference voltage generation circuit, 11
A reference voltage is applied from 2, and the output signal of the comparison circuit 113 is applied to a counter 114 for counting.

Note that the reference voltage generation circuit 112 is connected to the synchronous separation port 1s1G?
A signal serving as a reference for creating a reference voltage is obtained via the peak hold circuit 111. Further, a vertical synchronization signal V and a horizontal synchronization signal H are taken out from the synchronization separation circuit 107 by a synchronization port 9108, and from these, a reset signal R1 of the counter 105 is generated by a gate circuit 106.
A count gate signal Gt is generated, and a reset signal R of the counter 114 is similarly generated by the gate circuit 109.
2 and count gate signal G2 are generated.

FIG. 3 shows the operation of patterning the audio signal in FIG. The voice signal after removal, R1 is a reset signal given to the counter 105, and G is a count gate signal given to the counter 105. It is assumed here that the counter 105 operates while the count gate signal G1 is at a high level.

Therefore, the count gate signal G1 having almost the same waveform as the vertical synchronization signal V is applied to the counter 105, and the counter 1
05 counts the number of times the audio signal SA' crosses the level of the reference voltage applied from the reference voltage generation circuit 103 downward during the period T corresponding to approximately one field. And period T.

The subsequent sub-computer 30 at time t, immediately after the end of
The data is read by 0 and the next period T.

Just before the start of the reset signal, the counter 105
will be reset and will continue to operate in the same way.

Therefore, 60 pieces of data are read per second.

Next, FIG. 4 shows the operation of patterning the video signal in FIG. The video signal after removing unstable high frequency components and color components, R2 is a reset signal given to the counter 114, and G2 is a count gate signal given to the counter 114. Note that, similarly to the above, while the count gate signal G2 is at a high level, the counter 1
14 is assumed to be operating.

Therefore, there is a convergence T? 'T2b count gate signal G2 is generated. For example, the 64th to 29th horizontal synchronizing signals and the 19th
2nd to 207th), the sampling period is the upper part of the screen and the lower part of the screen, respectively, and the period T2. ．． T21. The number of times that the video signal SV' crosses the level of the reference voltage given from the reference voltage generation circuit 112 downward is counted (
The count value is the sum of the count value in the period T21 at the top of the screen and the count value in the period T2b at the bottom of the screen. ). Note that the peak hold circuit # is used as the reference voltage.
The peak value of the video signal Sv held at 111 is set to 172. Then, period T21. The data is read by the subsequent sub-computer 300 at time t2 immediately after the end of the field, and the counter 114 is reset by the reset signal R2 just before the start of the next field.
The operation of rrRa will continue thereafter. Therefore, in this case as well, 1
This means that 60 pieces of data will be read per second.

Although the above embodiment has been explained only for television commercials, it can also be applied to confirming the broadcast of radio commercials if only audio signals are targeted.

(Effects of the Invention) As described above, in the present invention, a plurality of TV commercials are patterned in advance and stored as data,
The currently received TV commercials are patterned by a data processing unit and compared with the stored data to determine the content of the TV commercials, making it possible to automatically check the broadcast of TV commercials. , it is effective in obtaining highly reliable results. In addition, it is possible to detect whether the broadcast was normal or not just by checking it.
