The monitoring device can also extract fingerprint data from the broadcast television signals, namely the television signals watched by audiences; then, the fingerprint data are transmitted to a data center; and the transmitted television signals are selected by the audiences for watching, and then are transmitted to a fingerprint matcher through the monitoring device to be monitored. The system provided by the invention does not need to change the prior assembled device when the monitoring device is arranged and connected.
Description
Technical field
The present invention is a system relevant with automatically monitoring television signal watching activities.
So-called in this field " fingerprint " refers to a series of image pattern information that filter out from digitized TV signal frame.And these frames are to select from all TV signal, and can select one or more sample value in each frame.Therefore, " fingerprint " can be used to discern said TV signal fully.
Background technology
In television broadcasting, the key issue that advertiser usually can ask is exactly that how many people are their TV programme have watch on earth.This key issue has determined the influence power of a concrete television advertising type to spectators colony.This is called as the channel level evaluation.It has determined advertiser to be ready to spend much price to remove to buy the advertisement position of a concrete television channel to a great extent.Concerning the station synchronization producer, yes wishes to have spectators as much as possible to watch their channel program for they, and they just can collect more advertising expenditure like this.And for advertiser and TV station, they wonder and watch numerical ratio accurately that they could be from the angle negotiation expense of oneself like this.
Along with the popularization of interactive TV, advertiser has all felt and need different observing patterns will have been arranged to concrete spectators colony with TV station.This is known as addressable target localization.This has been arranged, and advertiser just might be delivered to the information of oneself among the concrete spectators or spectators family.So just can improve the advertising message degree of correlation to a great extent, also improve the possibility that spectators become following consumer.
Therefore, just need measure spectators' activity of concrete channel.In other words, how many people need exactly has evaluate and test watching to a concrete television channel, is exactly to assess the needs that concrete spectators have watched which program carries out in addition.
Because the TV programme model that everyone is watched is evaluated and tested under normal conditions,, draw evaluation result more reliably so just can only extract a part of spectators as sample.These colonies can extract sample according to some demographic features, such as age, income level, education background, occupation or the like.When as assessment, sample colony just can be regarded as the agency of whole colony like this.Having had a lot of technology to be developed provides this information.
Wherein a kind of way is the diary to each sample or a papery of sample households.The sample spectators just need note the content of being seen when at every turn turning on TV.Their diary is regained termly again, gives data center and analyzes.
Another kind of way then is the remote controllers to dingus of each sample households and specific purposes.These remote controllers will be noted spectators' viewing information.These data also will be collected termly and the returned data center is analyzed as further.In each data center, watching activity all is that program arrangement when watching at that time interrelates, and just to obtain in which be that record is arranged to information period.
Also have a kind of way to revise broadcast singal by the programmer exactly, in not visible broadcast singal, embed the signal of some specific codings.The special device decoding that can in spectators family, be installed after these signals, thus know the TV programme that spectators watch.Decoded information again by the returned data center with performing an analysis.
Have, decoding with regard to the testing apparatus that is to use an audio frequency is hidden in audio code in that part of TV signal that can not hear again.Again with the decoding information gathering and the returned data center with performing an analysis.
The drawback of above first method is that the accuracy of assessing has very big problem, because need spectators' per 15 minutes (generally) will write the television content that they watch.Many times, the sample spectators have forgotten this work when seeing TV, and change platform continually and also be not suitable for such operation.
And second kind of way only is applicable to live TV programme, because operate the professional knowledge that it needs the program guiding in real time.Otherwise the selected television channel of only knowing certain specific period is to be not enough to decide content of TV program that spectators watch.For the TV programme that non real-time broadcasts, this method is just inapplicable.Such as, spectators can record into video recording PVR to the content of television broadcasting, allow the back fall back or F.F. in the different periods, suspend and rewinding.Under these circumstances, original program arrangement information just can not be used further to get in touch view content, unless need to change the hardware of PVR at least.In addition, this method also and be not suitable for the activity of watching of following the trail of other medium, such as DVD and personal media player, because there is not prior program calendar.Therefore, use the basis of this way to be to have the relevant program of prearranging row to broadcast table.But such requirement is not to be useful in fully under all usually situations.
Third and fourth kind of method all needs certain being modified in before signal sends to spectators done in the source of sending at signal to TV signal.But when complexity and adjust to require to be added in these and revise when going up, just not necessarily be suitable for.
Summary of the invention

Embodiment
This invention provides one accurately to determine the system of video content by monitoring equipment, so that monitoring can be used to set up a spectators's who is connected to equipment the model of watching.
This system comprises several key parts.First must have a hardware device to be arranged in spectators' the family exactly.One end of the equipment television set of ining succession, the TV signal that the other end is ined succession and.As shown in Figure 1.
Next, as shown in Figure 2, family each spectators, monitoring equipment 113 is the receiving terminals that are connected to video content source 110, also Monitoring Data (being called as finger print data here) is transferred to data center 104, simultaneously with the information that obtains from the source video sequence end is obtained to watch historical 105.
At Fig. 3, middle data center 104 is elaborated more, comprises two big key components.Video content memory 123 is key messages that are used to obtain from the video content 120 that broadcasts viewer's home 103.Stored video content has been represented the inlet of data center, and has been stored in the data center 124.And content matcher 125 directly 103 obtains finger print datas from spectators family, then with 124 in the content information of storage make comparisons.Last result is formatted to and watches in historical 105.
Fig. 4 has further set forth the interior details of video content memory 123, has comprised two big key components.Format converter 131 is to be used for various analog quantitys and digital video content format conversion are become the form that a suitable fingerprint memory 132 operates.More concrete explanation can be referring to Fig. 5, and format converter 131 further is decomposed into two modules here.
Then, Fig. 6 has further explained the intraware of fingerprint memory 132.
In a single day a video content is stored, and the long-range video content finger print data that its fingerprint also can be used to and collect mates.Therefore, just as shown in Figure 6, fingerprint memory will be used to store video content as much as possible.Ideal situation is that all video contents regardless of being sent to the spectators there all will be stored, so that they can automatically be identified when occurring on the video screen spectators.
In order to understand the operation workflow of data center better, two kinds of situations have been provided here.Under first kind of situation, as shown in Figure 7, video content 200 is to be stored in the video content memory 201 at first, and event memory is stored in the video content data center 202.This is to occur in video content really to be sent to before spectators' family.Afterwards, video content can be transferred in the content conveyer 203.At spectators' family, finger print data extracts 204 and carries out in the video content of transmission.
Under the another kind of situation, as shown in Figure 8, video content is transmitted by content conveyer 211, is stored in simultaneously in the content memorizer 213.Fingerprint extraction 212 takes place in video content transmission 211 simultaneously.Then, the finger print data of extraction can be transferred to data center and mate, and perhaps is temporarily stored in the equipment in the spectators family, is sent to data center afterwards again.
It is different with the order of storage that Fig. 7 and the key difference that can find two kinds of methods after Fig. 8 compares are that the video content of being correlated with transmits.
Next, Fig. 9 describes the process of video content coupling in detail.Clear and definite is exactly that content matcher receives finger print data stream from a lot of spectators' family 103, they is resolved in the different fingerprint matching devices again.And content matcher receives is the segment of real digital video content, carries out fingerprint extraction, finger print data is sent in fingerprint matching device and the form maker again.
Then, Figure 10 has described the operating process of fingerprint matching.
Figure 11 then is the operating process of having explained manager.
Getting off is exactly again, and the flow process in spectators family is also taken into account, as shown in figure 12.
Then, Figure 13 has specialized the operation of monitoring equipment 601.
The operation of another monitoring equipment 631 is embodied among Figure 14.
Should illustrate that the very important point is, in above specific process, the video of the input that spectators see four you do not have monitored device to do any change well.
In above discussion, supposed that audio signal and vision signal are transmitted together, further do not handle.
In addition, monitoring device need send back it data center to further process again in local store fingerprint data.Here have three kinds of way transmission data at least.A kind of concrete way of first-selection is that monitoring device is connected to the Internet, data back data center is further processed again.Another way is that it is one that there are a memory and monitoring device in this locality, can temporarily store the data of collecting, and upload the data to data center more termly.The third way then is, with monitoring device with one movably memory link to each other, such as USB flash memory, wherein with the finger print data storage.Spectators can extract removable memory termly then, and it is returned data center, change the memory of a blank again.
Next, Figure 15 has described the running of fingerprint extractor.In Figure 15, the frame of video 650 that the vision signal of datumization draws is sent to fingerprint extractor with the form of binary data.From the data of 651 outputs are the finger print datas 652 that extract, and size is little more a lot of than original video frame data 650 usually.
Figure 16 has further explained the intraware of fingerprint extractor 651.Concrete, frame of video 650 is to be sent to a frame buffer 660 at first, this is a data buffer that is used for temporarily storing digitized frame, and arranges by the order of image scanning.Part sampler 661 obtains image pattern and tissue samples from buffer 660, the result is sent to transmission buffer 662 again.Transmission buffer 662 transmits data again as finger print data stream.
Following Figure 17 expresses the inner working of fingerprint extractor in further detail.A kind of better statement is that each frame video is all sampled with same way.In other words, image pattern is to take a sample in the same position of different images, and the sample of equal number is obtained from different images.In addition, image is by continuous sampling.
Next sample can become the part of continuous images sample flow, is placed on transmission buffer 704.The image pattern of obtaining from different frame at this point is organized, before sending out.
Specifically, above sampling method can be expanded on the concrete way of first-selection, comprises above several variation: the sampled position of image can be different on each image; Can from different video images, obtain the sample of varying number; The image sampling process also can be carried out to noncontinuity, and in other words, the sample size of obtaining from each image may be different.
Above elaboration can be applied to other field, i.e. the general technical field of professional technique.These fields comprise (but being not limited only to these fields), and video content may be with MPEG-2, MPEG-4, H.264, and WMV, AVS, Real, perhaps following some other form is compressed.This system also can be used to monitoring audio frequency and voice signal.Equally, this system also can be used for monitoring the video content of being caught again by family or professional video image documentation equipment.Have, native system also can be expanded registration table and zone that is connected to the network of long range acquisition equipment that applies to as a concentrated video content unit sign again.
