0, input of other data 11 will be described. First,
The electronic cue sheet 10 is an electronic timetable created for the progress of the broadcast. The electronic cue sheet has been digitized from a cue sheet that has been conventionally described on paper, and can be easily accessed by broadcast staff. This electronic cue sheet 10
Is input via the I / F (interface) / G / W (gateway) 63 so as to be able to be analyzed, and a character string designated in advance is searched therefrom and extracted with time. For example, the contents of programs such as opening, CM1, sports corner, present corner, CM2, news, and ending are stored in association with time. In this way, the program information has been manually collected for the evaluation of the audience rating in the past, but the information is automatically displayed on the audience rating evaluation screen 64a as shown in 67d (see FIG. 4). Can be displayed. If all information is displayed on the audience rating evaluation screen 64a, it becomes rather difficult to see. Therefore, similarly to the video, clicking on the graph 67a may display the contents of the electronic cue sheet 10 at that time. .

Similarly, as other data 11, weather information provided by the Meteorological Agency or the like is analytically input via an I / F (interface) / G / W (gateway) 63 to extract necessary weather information. ": sunny temperature: maximum 23 degrees at least 7 degrees weather" on the graph as shown in FIG. 6 Te
May be displayed. Or it can be configured to display another portion of the audience rating screen 64a.

Next, the CM data extracting means 61 will be described. Here, a CM or a part estimated as a CM (hereinafter, referred to as a CM) is extracted from the video signal. Note that the CM extracted in this manner is, for example, a graph 6 in the present embodiment.
The line type of the corresponding portion of the polygonal line 7b (see FIG. 5) is changed from a solid line to a broken line and displayed. In addition, by changing the thickness or color of the graph 67b, the graph 67b is changed.
The list can be distinguished from the part other than the CM in b. In general, since the time of the CM is such that the channel of the television is significantly changed, it is significant to identify the CM portion in the evaluation of the audience rating.

Here, "CM" refers to the video and audio of a commercial message broadcast in television broadcasting. Broadcast time of this CM is generally 10 seconds, 15 seconds
In general, the time is short, such as seconds or 30 seconds, and the number exceeding 60 seconds is extremely small. Usually, it is almost 15 seconds. In addition, many CMs are common to all broadcasting stations, and are brought in from CM production companies and advertising agencies as so-called CM materials.

FIG. 9 is a time chart showing each timing in a CM of a video material. When inserting a CM material brought in from an advertisement production company at a predetermined broadcast time, a gap may occur in the cueing. In the case of video material, even in that case, normal CM
A portion of the image called a cushion is added to a portion before and after the symbol. For a 15-second CM, for example, 3
The material length is 21 seconds in total length by adding a cushion for each second.

Normally, a time scale is provided so that the beginning of the cushion is from -03 seconds to the end of the cushion, and the main program is usually broadcast from 00 seconds. A portion of the cushion, the first part of the main is constructed in consecutive images. In addition, the main part has a length of about 15 seconds and usually ends broadcasting in a time of +15 seconds. After that, a cushion is provided for 3 seconds, and the image continues until +18 seconds. The last part of this main part and the cushion after it are also continuous images. Therefore, the cushion is not usually broadcast, but the cushion is broadcast when the broadcast start time is around 00 seconds. In this case the first part of the front of the cushion and the CM, the last part of the back of the cushion and the CM is, because it is made with each successive image, some broadcast time not unnatural feel shifted back and forth. Here, the term “continuous” means, for example, an image that is recorded by a series of image capturing and has no seams. In addition, the composite screen includes an image corresponding thereto.

That is, the absolute time, for example, 20:00
Be the same CM material has been aired by minute 00 seconds, these televised portion will be that may be displaced in time. When judging whether these two CM materials are the same or not, comparing the respective images at the same absolute time, if the broadcast portion is temporally shifted, the same C even in the CM different
It is determined to be M.

Here, a discontinuous point at which the continuity of an image is interrupted and becomes discontinuous with the next image is referred to as a "picture substitute" in this description. If the same CM, a picture substitute occurs at the same time. Therefore, by detecting this picture instead, its Taking the same time axis based on the picture instead, will be able to determine whether identical or not by comparing the image of the two CM. In the present embodiment, first, an image is sampled for each frame, that is, at an interval shorter than 1/30 second, and the brightness or the hue of the pixel at the same position is compared between the frame and the immediately preceding frame. The difference is extracted as a difference, and the ratio of the difference to the whole is obtained. If the difference is equal to or more than a predetermined ratio, it is determined that the image has significantly changed. In other words, the videos are compared in chronological order to determine the autocorrelation,
The place where the change greatly, that is, the moment when the autocorrelation is lost is determined to be a picture substitute.

The CM of a film material is the same as the CM of a video material except that the cushion is only 0.5 seconds before and after and the screen changes at 24 frames per second. Therefore, it is desirable to set the sampling interval to 1/30 second or less, which is the frame interval in the case of a video material, since a picture substitute can be accurately detected. However, generally CM
Is 15 seconds long, and the audience rating data is in units of 1 minute, so not so high precision is required. Even if the sampling interval is not more than 1/30 second, In the present invention, detection can be performed with sufficient accuracy. In addition,
Actually, even if it is not a picture substitute, if it is a moving image, if the brightness and hue at the same point on the screen change greatly due to panning and zooming other than the movement of the object, it may be judged as a picture substitute There is. Even in such a case, it is possible to obtain the effect of the present invention because a time reference can be made by determining that a non-picture substitute portion at the same time in the same CM material is a picture substitute.

As described above, when a picture substitute, which is a discontinuous point of an image detected on the basis of autocorrelation, is used as a temporal reference, if the same CM material is used, the same CM material at the same point on the screen at the same time is used. Also have the same brightness and hue.

As described above, in order to determine whether or not an unknown video is a CM, this picture replacement is detected and a predetermined delay time, for example 1 /
After 30 seconds, video sampling is performed. And already C
In a known video signal that is known to be M, the brightness of the image 1/30 seconds after the delay time from the picture replacement is detected as feature data, and this is compared with the feature data of the video to be determined. If the feature data matches, it is understood that the CM is the same as a known CM. Of course, RGB color balance and the like may be compared instead of brightness.

Here, since the feature data sampled in this way needs to be matched with the feature data of a large number of known CMs, the size of the feature data is reduced in order to speed up the processing in real-time processing. small it is desirable. Here, FIG. 8 shows an example of the sampling screen. FIG. 8 (a), the (b), the on screen S1,
S2, S3, determines the S4, S5 five regions of calculating this five respective average brightness. As described above, by comparing only a part of the screen, the feature data can be reduced. Alternatively, pixels to be displayed are set at a predetermined interval, for example, 1
00 and methods as compared to extraction with pixel spacing, 1
Alternatively, a method of extracting and comparing pixels of a plurality of horizontal scanning lines may be used. In other words, instead of comparing the pixels of the entire screen, they are extracted from some of them and compared.
What is necessary is just information at a position where the difference is easy to compare. Data server 6 for the procedure as described above is an example of a discontinuous point detecting means, the image feature extraction means, a video CM determination means of the present invention.

In the method described above, the CM data is extracted using the identity on the screen. However, the sound may be sampled on the basis of the picture substitute time and compared. Similarly, when a substitute for a picture is detected, after a predetermined time elapses based on the time when the substitute for a picture is determined, the CM
May be sampled, and the CM data stored in the CM data storage means may be compared with the audio data of the CM to be determined to determine the identity. Note that the data server 6 performing such a procedure is an example of the voice feature extraction unit and the voice CM determination unit of the present invention.

In a television broadcasting station, an identification signal indicating the content of a CM is added to a master tape on which the content to be broadcast is finally edited. The identification signal added to the master tape is erased immediately before the broadcast, and the signal is not actually broadcast. However, the CM can be reliably detected using the signal within the own station. . This is I / F
The data is input from the G / W 63 and displayed on a graph by the rating evaluation screen synthesizing means.

In a commercial, a specific company has an identification means called a jingle, a sound logo, or the like that indicates the company by voice using a certain scale or a catch phrase. Here, a jingle, a sound logo, and anything that plays a fixed sound are collectively referred to as a “jingle”. Since such voice containing jingles can be estimated as a CM, in advance from the known CM Record jingles, etc., and searches for matching the voice data determination target this same voice is detected When it is completed, the target is determined to be CM. The data server 6 that performs such a procedure is an example of the jingle CM determination unit of the present invention.

Further, in a CM, sound is almost always a stereo signal. Monaural signal is large in the general program the contrary. Also, the CM is 15
While those seconds will air in combination, typically 18
Those of more than 0 seconds is rare. Therefore, since the audio signal to be determined is a stereo signal and a signal within 180 seconds can be estimated to be a CM, the determination target is determined to be a CM. The data server 6 to carry out such procedure is an example of a stereo signal CM determination means of the present invention.

[0073] Since generally a plurality of CM is broadcast continuously it is large, if there is a short time between the CM and the CM, are likely to be CM with high probability. Therefore, a signal that is already sandwiched between CMs or a time predicted as a CM and that is within 60 seconds, for example, is regarded as a CM and processing is performed. Note that the data server 6 performing such a procedure is an example of the exclusive CM determination means of the present invention.

The sound at the front and rear ends of a CM is often silent. Of course, a silent state often appears in ordinary voices, but in the case of commercials, most of them are 15 seconds. In general, since four or more commercials are combined and aired, there are three silent states at 15-second intervals. If it exists more than once, it is highly possible that the sound surrounded by the silent part is that of a commercial. Of course, the greater the number of consecutive times, the higher the probability of being a CM. On the other hand, since there are many voice parts in the CM, if the duration of the silent state is equal to or longer than a certain time, it can be estimated that the probability of the CM is low. Therefore, 1
If there are three or more silence states at 5-second intervals and the duration of each silence state is equal to or less than a certain time, it may be regarded as a CM.

[0075] In addition, cut out but there is a case in which, such as breaking news is inserted as a super on the screen in the television broadcast, and a string of, for example, breaking news from the screen, the character string to be continuous to the string, time information Extract with. To cut out a character, for example, an outline of the character is extracted by edge detection, and character recognition is performed by dictionary matching. For example, "Breaking news: Cabinet dissolution. Next year 1
Month general election. , "
Simultaneously stores the a reception time period of 10:15, as the graph 67b shown in FIG. 6, 10 on the graph
Characters are displayed at the position of 15 to indicate that the breaking news was at the broadcast station indicated by the graph at 10:15. Then, the audience rating screen combining unit 64 to be displayed on the graph 64b viewership ratings screen 64a shown in FIG. In this case as well, only the fact that there is a breaking news may be displayed on the graph 64b, and the content may be displayed by clicking a predetermined area.

[0076] Reference is now made to FIGS. 1 to 15 for the procedure for the use of audience rating system 1 configured in this manner. First, a signal is always input from the receiving means 2, and the input signal is synthesized and encoded by the synthesizing means 3 and the encoding means 41, and is appropriately divided and named in the storage means 43, for example, every hour. Automatically memorize.

When the audience rating is evaluated, a predetermined URL is designated by the browser from the operation terminal 5 and the data server 6 is accessed via the Internet 12. Then, a menu screen (not shown) is displayed. From the menu screen, a menu linking to the program selection screen 66a (FIG. 12) or the time selection screen 66b (FIG. 14) is displayed. The display changes on the screen. On the program selection screen 66a, by selecting and clicking a program whose rating is to be evaluated,
A rating evaluation screen 64a is displayed together with the program-specific reference information 64d. Further, the time selection screen 66b, date, start time, fill in the end time, select the television station by operating the query transmission button, audience ratings screen 64a is displayed together with the time another reference information 64f. In this case, the video screen is displayed from the first displayed time of the quadrant. At this time, a video screen can be switched to a screen of any one company or a graph 64b can be switched to a graph 67a of only one company shown in FIG. 4 from a pull-down menu or a pop-up menu (not shown).

The operator, in addition to the graph 64b of the audience rating evaluation screen 64a displayed on the operation terminal 5, displays the hourly reference information 6
4f or program-specific reference information 64d, such as by referring to the reference information 64c displayed further on the graph, the mouse was moved to the position of the time to be evaluated on the on-axis or time graph by clicking at that location. Then, the data requesting the video is transmitted to the WWW server 62 of the data server 6 together with the time data, and the WWW server 62 activates the CGI and returns the information indicating the URL to the operation terminal 5, and the operation terminal 5
Transmits a request for the content of transmitting the video to the output control means 44 of the recording / delivery server 4 of the URL designated here. The output control unit 44 that has received the transmission reads the video at the designated time from the storage unit 43 and stream-transmits the video to the operation terminal 5 via the Internet 12. In this way, by reading the fluctuation of the audience rating, referring to the information on the screen at that time, analyzing the cause of the increase or decrease of the audience rating, and confirming the video at the time of the fluctuation, especially including other companies, the fluctuation of the audience rating Can be easily and accurately analyzed.

[0079] According to audience rating system 1 (Effect) In the above embodiment, it is possible to obtain the following effects. The audience rating evaluation screen synthesizing means 64 simultaneously displays a graph 64b showing the audience rating for each time, information 64c related to the audience rating displayed on the graph 64b, and the encoded video 64e at the same time. It can be displayed on 64a. Further, the video output control means 44 can display a video based on the specified time on the audience rating evaluation screen 64a by operating a predetermined area associated with the time on the displayed graph 64b. Therefore, there is an effect that it is possible to evaluate the ease and multifaceted viewership with reference to a number of information necessary for the evaluation of the audience simultaneously.

In the audience rating evaluation screen 64a, data relating to a CM whose audience rating fluctuates generally can be displayed, so that it is possible to easily determine the audience rating.

The HDD 68 serving as CM data storage means
The video and audio signals of the existing CM stored in the video signal and the input video signal are each detected as a picture substitute, thereby eliminating the time lag of the video to be compared, and sampling the video at this timing. By comparing the extracted features, it is possible to determine whether or not the video signal is a CM, and it is possible to extract only the CM.

The timing of the image to be compared is eliminated by detecting the picture substitute which is a discontinuous point between the video and audio signals of the existing CM stored in the HDD 68 and the input video signal, thereby eliminating the time lag. By comparing the features extracted by sampling the video, it is possible to determine whether or not the video signal is a CM and extract only the CM.
