(4) resolve and to cut out key word by carry out profile element for the contained content of record information, the number of times (frequency) that key word is occurred is provided as each value of account attribute information.
Like this, account attribute extraction unit 34 generates the account attribute information for the E-News of all receptions, but the profile element dissection process that carry out above-mentioned (4) also can be realized by the method for merely extracting Chinese character continuous part and katakana continuous part etc. from text strings out simply.In Fig. 7, for example, extract words such as " performer A ", " actress C ", " marriage " out with frequency 1 respectively from the E-News account content of the 1st row (account number 1) of Fig. 6.The account attribute information of this content is delivered to account reading monitoring unit 37 and media information evaluation portion 18 after being generated automatically by account attribute extraction unit 34.
Program attribute information (Fig. 4) project that account attribute information (Fig. 7) project that the attribute extraction unit 34 of relatively keeping record generates and programme attribute extraction unit 33 generate is just known, in the present embodiment, even under the different situation in media information source, also can generate the attribute information of same form.
In addition, account reading monitoring unit 37 is by constantly monitoring the work of electronic reading portion 31, the monitoring user E-News of whether having read.So, when the user has read certain E-News, generate and the relevant account monitor message of reading of E-News according to the account attribute information.Fig. 8 generate for expression account reading monitoring unit 37 and output the figure of account monitor message example, content shown in Figure 8 is, account reading monitoring unit 37 receives the account monitor message example that account attribute information shown in Figure 7 and user have read and exported under the account situation of Fig. 7 first row in E-News Reading Room 31.As shown in Figure 8, each project of account monitor message by classification (kind or key word), content, be worth the performance of this group, by following such generation.
(1) for the classification of account attribute information, the generation classification is that kind, content are that categorised content (" society " among Fig. 8), value are projects such as 1.0.
(2) for key word and the value one group of account in the attribute information, generating classification respectively is that (" performer A " " the actress C " among Fig. 8 reaches projects such as " marriage " and value for the content of key word for " key word ", content.
Like this, the reading of the account in present embodiment monitoring unit 37 generates and output account monitor message.The user reads when may not supply with record information, so account reading monitoring unit 37 need be fixed time the account attribute information that provided by reading or from providing after in inner or outside certain of preserving at least one group note (Fig. 6 is 2 accounts) to process certain hour etc.
Relatively program monitor message (Fig. 5) project of account monitor message (Fig. 8) project of account reading monitoring unit 37 generations and 36 generations of program audiovisual monitor message portion just as can be known, in the present embodiment, even under the different situation in media information source, also can generate the monitor message of same form.
At last, just relevant with page information processing describes.
At first, described media information source and new to the information source difference.Www server 25 and page or leaf are new, and therefore, at this, page or leaf newly sends request termly to information request portion 39 to information server 29 output medium information etc. automatically not, page newly arrives an information mainly page or leaf newly arrive information server 29 transmissions.Its result, page or leaf is new newly to be sent here by WWW agency (proxy) server 27 to information server 29 to information from page or leaf.Fig. 9 is the new new figure to the information example of page or leaf to information server 29 outputs of expression page or leaf.As shown in Figure 9, the new projects of information that arrive of page or leaf are by showing with same form with the project of program attribute information (Fig. 4) and the project of account attribute information (Fig. 7).Therefore, the page or leaf that page attribute extraction unit 35 is received is newly delivered to page information reading monitoring unit 38 and media information evaluation portion 18 with constant form as page attribute information to information, that is, page attribute extraction unit 35 need not carry out with the same attribute information of above-mentioned attribute device generate handle also passable.
Figure 10 is the figure of the page information example of expression www server 25 outputs.This page information is specified by URL (Universal Resource Locator) [http://www.aaa.co.jp/] from page information Reading Room 32 the user under the situation of www server 25 of unidirectional identification, www server 25 outputs by correspondence, its result delivers to page information Reading Room 32 and page attribute information extraction unit 35.The content of page information is by the form record that is called as HTML (Hypertext Markup Language).
Figure 11 is for the figure of expression page information Reading Room 32 picture displayed examples, for showing the picture example under the page information situation shown in Figure 10.In Figure 11, URL information shows at URL display field 40.And, in the page information shown in Figure 10 by＜TITLE and＜TITLE the text strings " homepage of TV play 1 " of surrounding shows at the title display field.Other guide shows at content display part 42 according to the institute's formula that fixes by the decision of HTML style.
After page attribute extraction unit 35 receives page information shown in Figure 10, generate page attribute information.Figure 12 generates with following method for the figure of expression page attribute extraction unit 35 according to the page attribute information example of page information generation shown in Figure 10.
(1) appends the information of presentation medium information source for " WWW ".
(2) with URL as access method.
(3) append content and be empty kind.
(4) content that comprises for page information is removed and is resembled＜HTML〉part (html tag) of surrounding with the sign of inequality, by carrying out the profile element parsing, cut out key word, the number of times (frequency) that each key word is occurred is provided as each value of page attribute information.
Like this, page attribute extraction unit 35 generates page attribute information, and the profile element dissection process that above-mentioned (4) are carried out is similarly carried out with account attribute extraction unit 34.Just, as word " homepage ", be considered to the insignificant word that do not need as key word and will delete processing.This can adopt the method for using the stop words dictionary data that comprises stop words.Therefore, as shown in figure 12, can " homepage " do not handled as key word.
And, compare as can be known with programme attribute (Fig. 4) project and account attribute information (Fig. 7) project by page attribute information (Figure 12) project that page attribute extraction unit 35 is generated, in the present embodiment, even under the different situation in media information source, also can generate the attribute information of same form.
In addition, page information reading monitoring unit 38 by the work of continuous supervision page information Reading Room 32 the monitoring user page information of whether having read.So, when the user has read page information, generate the page or leaf monitor message relevant with the page information of reading according to page attribute information.Figure 13 is the figure of the page or leaf monitor message example of expression page information reading monitoring unit 38 generations and output, and as shown in figure 13, projects of page or leaf monitor message are by classification, content, one group of embodiment of value, by following such generation.Promptly, page information reading monitoring unit 38 is respectively for one group of the key word in the page attribute information and value, and the generation classification is that key word, content are that (" TV play 1 " " during the photography " " inner thing " among Figure 13 reaches projects such as " performer A " and value thereof for the content of key word.At this, the user passes through page information Reading Room 32 reading page informations in the moment that page information is provided, and simultaneously, page attribute extraction unit 35 is because of generating page attribute information, so page information reading monitoring unit 38 needn't be preserved page information.
Page information is read program monitor message (Fig. 5) project that account monitor message (Fig. 8) project that page or leaf monitor message (Figure 13) project that monitoring unit 38 generates and account reading monitoring unit 37 generate and program audiovisual monitoring unit 36 generate more as can be known, in the present embodiment, even under the different situation in media information source, also can generate the monitor message of same form.
By above processing,, all deliver to history information management portion 16 by the monitor message that user's audiovisual, reading generate for media information from each media information source output.And, newly deliver to media information evaluation portion 18 to information with the form that is transformed to attribute information from each to the new of information source output.
Below, the processing that has just received the history information management portion 16 of monitor message describes.16 unified managements of history information management portion are according to the record information of the record information generation/renewal of each access monitoring arrangement output of program audiovisual monitoring unit 36 grades, but not as only being the resume data storage of access resume, the load value that is distributed according to each media information source, give load value and generate record information, this is its feature.Therefore, before the processing of explanation history information management portion 16, describe with regard to the work of media information source load value setting device.
Figure 14 is stored in the figure of the load value information setting example of load value information storage part 21 for expression.Load value information is the information of the load value of the monitor message of setting the media information source, so that the media information source is embodied as one group with corresponding load value.In Figure 14, set 1.0,0.5,0.5 load value respectively for the information source 23 of televising, E-News information source 24, www server 25.This load value is set input from load value information setting portion 20 through input and output handling part 22 by the user.The user can carry out the reference and the renewal of load value information by operation input and output handling part 22.Certainly, also load value information predetermined fixed can be stored in load value information storage part 21.
History information management portion 16 is stored in the renewal of the record information of record information storage part 17 after sending each record information here from program audiovisual monitoring unit 36 grades.
Figure 15 is the figure of expression record information content example.As shown in figure 15, record information is made of monitor message and identical items (classification, content, value), expression be the result who adds up respectively according to program monitor message shown in Figure 5, account monitor message shown in Figure 8 and page or leaf monitor message shown in Figure 13.Before it, suppose that the value that is stored in record information storage part 17 all is 0, the value that then is contained in record information is calculated like that by following.
When calculating, history information management portion 16 will be accumulated to record information to the value of this load monitor message on duty with reference to the load value information that is stored in load value information storage part 21.That is, about media information source i, for classification c, content w, value V CwWhen being apprised of history information management portion 16, the load value of supposing media information source i is A i, the value that up to the present is stored in classification c, the content w of the record information of record information storage part 17 is H n, then newly be stored in the value H of record information memory storage N+1For:
Hn +1＝H n+A i·V cw
For example, about " performer A " this key word, the value among Fig. 5 is 1.0, and the value among Fig. 8 is 1.0, and the value among Figure 13 is 1.0.When receiving these monitor messages, multiply by load value shown in Figure 14 and addition respectively at every turn.At first, behind the program receiving monitor message, have:
H1＝0+1.5×1.0
Then, behind the reception monitor message, have:
H2＝1.0+0.5×1.0
Then, behind the reception page or leaf monitor message, have:
H3＝1.5+0.5×1.0＝2.0
Its result becomes value shown in Figure 15.Equally, about " TV play 1 " this key word, be 1.0 in Fig. 5, because of in Fig. 8, there not being reference,, be 2.0 in Figure 13 so be 0.0, so, have:
H3＝((0+1.0×1.0)+0.5×0.0)+0.5×2.0＝2.0
Its result becomes value shown in Figure 15.History information management portion 16 is by carrying out above processing, can unified management for access resume from the media information of different record information source output.
In addition, when media information evaluation portion 18 waits each attribute withdrawing device to send attribute information here respectively from programme attribute extraction unit 33,, calculate with following method and estimate by comparing with the record information that is stored in record information storage part 17.That is, the kind of supposing to be contained in attribute information is g, for key word W iValue be V i, the kind value that is stored in the record information of record information storage part 17 is H g, for key word W iValue be H i, then evaluation of estimate E calculates with following formula:
E＝H g+H iV i
For example, when record information storage part 17 is stored record information shown in Figure 15, it is new under the situation of information that media information evaluation portion 18 has received page or leaf shown in Figure 9, information [http://www.aaa.co.jp/] for first row, because of having at record information storage part 17, kind is that " epoch play " (value 1.0), key word are the record information of " performer A " (value 2.0), so, have:
E＝1.0+2.0×3.0＝7.0
And, for the information [http://www.bbb.co.jp] of second row,, only just become the evaluation of key word " actress C " because of there not being the record information of kind shown in Figure 15 " terror " and key word " film X ", have:
E＝0.5×2.0＝1.0
When media information evaluation portion 18 surpasses certain threshold values in above-mentioned evaluation of estimate, attribute information is delivered to media information recommending portion 19.For example, the threshold value setting of media information evaluation portion 18 is under 3.0 the situation, according to the result of calculation of above-mentioned evaluation of estimate, has only the page or leaf of first row shown in Figure 9 newly to be sent to media information recommending portion 19 to information.
Though media information evaluation portion 18 has carried out above processing, in the present embodiment, because of the attribute information of comparison other and record information are formed with same form by each access monitoring arrangement and each attribute withdrawing device, so above-mentioned comparison process can easily be carried out.
Figure 16 is the display frame of media information recommending portion 19, and media information recommending portion 19 will resemble from the attribute information that media information evaluation portion 18 sends here Figure 16 and show through input and output handling part 22, in view of the above, the user be carried out the recommendation of media information.
According to present embodiment, because of will managing for the access resume unification of the media information of a plurality of media informations source output, so, even under, also can carry out the high recommendation of accuracy for the few situation of the access times in single media information source.And, even sending the media information of different pieces of information structure here from different media information sources and during newly to information, because of monitor message and attribute information being generated as same form, easily carry out so can make based on each information processing in single history information management portion 16 and the media information evaluation portion 18, management by access monitoring arrangement and attribute withdrawing device.
And, because of setting the load value in each media information source, so can between each media information source, adjust balance by record information reflected.
In the present embodiment, be after page or leaf newly sends request to information request portion 39, provide relevant with WWW from page or leaf hardworking information server 29 newly to information, but also can be as searcher (searchengine), the www server 25 that page attribute extraction unit 35 is sought all over be present in external network 26 carries out attribute from all www servers 25 and extracts out and handle.
And, in the present embodiment, be with TV programme, E-News, WWW as object, certainly, the combination of the media information beyond it is also belonged to scope of the present invention.For example, for media information sources such as CD-DA, literal broadcast, e-shop, Emails, can with same structure shown in Figure 1, obtain and same effect shown in Figure 2.
And, in the present embodiment, adopt be with attribute withdrawing device and access monitoring arrangement respectively with each media information source and new to the corresponding structure of information source, handle complicated attribute withdrawing device and access monitoring arrangement in each device and constitute with single device respectively but also can make.
Embodiment 2
Figure 18 is the frame assumption diagram that the embodiment 2 of the media information recommending apparatus relevant with the present invention is shown.In Figure 18, operation inputting part 61 is accepted user's input operation.Information output apparatus 63 output comes the media information in the media information source 62 that free users select by operation inputting part 61 from a plurality of media informations source.Information attention degree evaluation portion 64 estimates the information attention degree of expression user for the degree of concern of this media information according to the behavior of the user between the information output apparatus 63 output medium information.The resume and the information attention degree of the input operation that record information storage part 65 storage operation input parts 61 are accepted.Media information recommending portion 66 is according to canned data attention rate in the record information storage part 65 etc., from newly carrying out to the information of sending here the recommendation with user's the corresponding to media information of hobby.Range determination portion 67 is the devices that are used to measure the distance between user and the information output apparatus 63, waits with the method for stereo display of ultrasonic sensor, image and realizes.In the present embodiment, owing to set the embodiment of media information recommending apparatus that reading comprises listened to the media information of sound, so information output apparatus 63 has the information display section 68 and the audio output unit 69 of output medium information on picture etc.Audio output unit 69 takes out audible information (voice signal) and output from the media information that can listen media information or be accepted.
Media information recommending apparatus in the present embodiment also can be applicable to a plurality of media informations source by said structure being corresponded respectively to the media information source, but owing to will not be applied to a plurality of media informations source this point as feature, so only export the feature that the single medium information source illustrates present embodiment for convenience's sake.
Feature in the present embodiment not only is selection number of times and the reading time of user for media information, if and be to be conceived to the situation that user's reading in the past judged (as the reading time be gate time), promptly from the situation of information output apparatus 63 output medium information, whether the user pays close attention to this media information in reality.Whether the user pays close attention to this media information this point in reality, not only according to the selection behavior of user's behavior, the media information that for example obtains from operation inputting part 61, and according to after selection from behaviors such as the volume of audio output unit 69 output and volume adjustment, or wait by the range information that range determination portion 67 obtains and to judge.In the present embodiment, owing to estimate the information attention degree of user for this media information according to such user's behavior, so can carry out the recommendation of the higher media information of accuracy.
Secondly, the work of present embodiment is described.
The volume that the user utilizes operation inputting part 61 to adjust from audio output unit 69, and the volume value announcement information attention rate evaluation portion 64 that operation inputting part 61 will newly arrive when the user adjusts volume.On the other hand, range determination portion 67 often measures the distances between users and the information output apparatus 63, when this measured value variation or termly announcement information attention rate evaluation portion 64.
The value of the distance that information attention degree evaluation portion 64 measures volume value and range determination portion 67 from operation inputting part 61 notices in official hour unit respectively averages.Utilize following method evaluation information attention rate again.
Information attention degree=A * (reading time)+B * (time average of volume value)+C * (time average of distance) (A, B, C are coefficients)
The information attention degree that media information recommending portion 66 will calculate as described above is added to the recommendation of carrying out that comes information that the user is carried out in the access resume of media information over.If interesting information then exists the user to reach near the possibility of carrying out audiovisual display frame with big volume.For example, if do not plan to leak the radio broadcasting of listening, then listen to big volume if do not plan to leak televising of seeing, near the situation of then carrying out audiovisual TV is many.Have, after the media information of having selected to follow the demonstration of televising etc., if it is bigger to measure distance, the possibility of then not carrying out audiovisual is very big again.Thereby the judgement material of interest is taken into as having not by the behavior with such user, only obtaining under the situation of information attention degree according to the reading time, can carry out the higher information recommendation of accuracy.
But, in above-mentioned example, merely calculate the information attention degree according to the Determination of distance value of volume value and user and information output apparatus 63.This be because, as mentioned above if interesting information, then with big volume and to carry out the situation of audiovisual near display frame many.But, can not calculate the information attention degree according to relative variable quantity according to such absolute value yet.This be because, if the information that the user is interested in, then with bigger volume and very big in the possibility of carrying out audiovisual more nearby of display frame.
In addition, in above-mentioned example, to each coefficient A, B, C of going up on duty.Wish the media information change setting of this value according to reading.This be because, for example, if radio broadcasting, and if in the scope that the user can listen to reliably improving volume, then not necessarily be sitting in the situation before the loudspeaker.So, must consider that the environment that utilizes of user's media information sets coefficient.In addition, if the music program of air cast, then the interdependence for volume value is bigger, and if sports cast is then compared relatively less for the interdependency of volume value with music program.
Embodiment 3
Figure 19 is the pie graph that the embodiment 3 of the media information recommending apparatus relevant with the present invention is shown.Structure in the present embodiment is identical with embodiment 2 basically with work, and situation more that the foregoing description is 2 more specific, that promptly be applied to televise is an example.
In Figure 19, operation inputting part 71 receives user's input operation.Input operation described here, if consider from input operations such as the telepilot of TV and guidance panels, then if can easily imagine like that, be the selection operation, volume adjustment operation etc. of switching manipulation, the channel of power supply.The portion 73 that televises is equivalent to information output apparatus, and output comes the media information of the channel that free user selects by operation inputting part 71 from the information source 72 of televising with a plurality of channels.Media information described here is the program of broadcasting in each channel.Program is different with getable media information via internet when liking, and is the media information with feature of broadcasting in the predetermined time period according to broadcasting schedule in principle.Televising comprises the audio output unit 69 shown in the embodiment 2 in the portion 73, shows after will being transformed to image, sound respectively from the picture intelligence of the information source 72 of televising and voice signal.Have, it also is the programme information source of supplying with the listing information that is equivalent to EPG that the information source of televising 72 is not only picture intelligence, the voice signal of supplying with TV programme again.Information attention degree evaluation portion 74 estimates the information attention degree of media information similarly to Example 2, and estimates the degree of concern for each program here.In the present embodiment, with the user to the degree of concern of program, be that the information attention degree is called the program attention rate especially.Corresponding to program of hobby and recommendation with the user are selected according to the program attention rate of storage in the record information storage part 75 by programme information recommendation portion 76 from the listing information of sending here.Have, record information storage part 75 and range determination portion 77 are equivalent to record information storage part 65 and the range determination portion 67 of embodiment 2 respectively again.
Have again, below the feature of input operation is called " incident (event) ".In addition, the notice of power connection is called " power connection incident ", the notice of power remove is called " power remove incident ", the notice of the input operation of channel operation is called " channel incident ", the notice of the input operation of volume adjustment operation is called " volume incident ".Input operation part 71 is accepted the input operation that the user carries out, with these event notices televise portion 73 and program attention rate evaluation portion 74.Portion 73 accepts the notice of incident if televise, and then carries out the control of channel selection etc. according to the kind of incident.
Secondly, while enumerate the work that concrete example illustrates present embodiment.
Figure 20 is the figure that the configuration example of the listing information of exporting in the programme information source is shown.The channel supposition of televising in the present embodiment, is three of channel A, channel B, channel C.In listing information, put down in writing the information of program names, reproduction time, channel with the form of table with respect to each program.For example, in channel A from 18: 00 to 19: 00 the program of broadcast program by name " news ".This listing information is delivered in program attention rate evaluation portion 74 and the programme information recommendation portion 76.
Figure 21 is the figure of example of resume that the incident of operation inputting part 71 notice is shown.In Figure 21, in " incident " hurdle on the right side of showing, with the incident of " on " expression power connection, with the incident of " ch " expression channel selection, the incident of using " Vol " expression volume to adjust is with the incident of " off " expression power remove.In addition, the selected channel name of the symbolic representation after " ch ", the adjusted volume value of numeral volume after " Vol ".Moreover, represent to notify " constantly " of each incident on the left hurdle of table.
Have again, carry out input operation and the generation incident by the user, but by way of exception, when carrying out the input operation of power connection, to carry out last time during power remove selecteed channel as selecteed channel incident, to carry out the volume value of last time during power remove as the volume incident that is set, no matter how automatically operation inputting part 71 user's operation notice televise portion 73 and program attention rate evaluation portion 74.In Figure 21, show when 18: 58 carry out the input operation of power connection by the user, will select the channel incident of channel B and volume value be adjusted to 10 volume incident simultaneously by the example of operation inputting part 71 notices.That is, when the user has carried out the power remove of last time, selected channel B as can be known, in addition, volume value is 10.In Figure 21, incident is in addition all carried out input operation by the user and is taken place, and for example, in the input operation of 18: 59 component selections channel A, at 19: 00 volume value is adjusted to 16 input operation and is undertaken by the user respectively.Have, become simple in order to make explanation, input operation is carried out with zero second the timing in whole moment, also carries out the notice of incident simultaneously.As mentioned above, if operation inputting part 71 is accepted user's input operation, then simultaneously the portion of televising 73 and program attention rate evaluation portion 74 are carried out the notice of incident.
On the other hand, range determination portion 77 measures user who changes constantly and the distance of televising between the portion 73, notifies program attention rate evaluation portion 74.Program attention rate evaluation portion 74 is to calculate the user every 1 hour interval and the time average of the distance between the portion 73 of televising, i.e. " apart from time average ".
Figure 22 is the figure apart from the example of time average that illustrates that program attention rate evaluation portion 74 calculates.In Figure 22, left hurdle represents that every 1 hour time period, right hurdle was represented apart from time average.For example, showing is 5 meters from time period of 18: 00 to 19: 00 apart from time average.
Program attention rate evaluation portion 74 calculates the program attention rate with respect to each program of the channel of user's selection and audiovisual with following formula.
(program attention rate)=
(elapsed time evaluation of estimate)+
(volume operation frequency evaluation of estimate)+
(apart from evaluation of estimate)+
(volume evaluation of estimate)+
(time period evaluation of estimate)+
(channel selection frequency evaluation of estimate)
The elapsed time evaluation of estimate is an Evaluation and Selection plays after the channel of program of evaluation object to the value in the elapsed time of the broadcast that begins this program.Volume operation frequency evaluation of estimate is to estimate the value of the frequency of the volume adjustment operation in the playing programs.Apart from evaluation of estimate is to estimate the value of the close degree of the televise portion 73 of user in playing programs.The volume evaluation of estimate is the value of the volume when estimating the broadcast of user's audiovisual material.The time period evaluation of estimate is to estimate the timing of the channel selection operation of being undertaken by the user and the value of the consistent degree of the reproduction time of certain program.Channel selection frequency evaluation of estimate is to estimate the value of the frequency of the channel selection operation of being undertaken by the user.Below be described in detail about these every calculation methods.At first, the elapsed time evaluation of estimate is described.
The user pays close attention to the possibility of the program of this cannel broadcast higher after having selected channel in soon time.And perhaps the user can continue this program of audiovisual.But, consider that from another point of view As time goes on, the user disseats or begins audiovisual activity in addition, the possibility of not too paying close attention to this program increases.Therefore, the program attention rate can be calculated as the minimizing function of having selected the channel elapsed time afterwards.In addition, the user changes the so-called remote control of channel continually and changes under the situation of platform, and can think does not have media information in the special concern reading.Thereby, by with the program attention rate as the function of having selected the elapsed time after the channel, and the function that in the elapsed time is zone more than the certain value, reduces along with the increase in above-mentioned elapsed time and calculating, can more correctly estimate the degree of concern of user for program.In the present embodiment, from the viewpoint, with the elapsed time evaluation of estimate as being used to one of index of estimating the program attention rate.
Thereby in fact program attention rate evaluation portion 74 calculates " elapsed time evaluation of estimate " by each program of selecting channel to continue audiovisual with respect to the user.But the user does not necessarily change channel fully in the program audiovisual.That is, can easily imagine the user and select other channel among by the program of certain cannel broadcast, select the situation of the channel of this program thereafter once more in audiovisual.Under these circumstances, the time period with this program of user's audiovisual is divided into several.For example, according to Figure 20, in channel B from 20: 00 assign to 21: 00 broadcast " epoch play 2 " program.The user carries out under the situation of input operation as the example of Figure 21, and the user is assigning between 20: 26 7 minutes and audiovisual material " epoch play 2 " in 20: 40 2 time periods assigning between 20: 47 7 minutes from 20: 19.Have, the situation of each time period during with certain program of user's audiovisual is called " part audiovisual time period " again.As mentioned above, there are a plurality of part audiovisual time periods with respect to 1 program.The value that is called following " part audiovisual time period evaluation of estimate " is calculated with respect to each of these part audiovisual time periods by program attention rate evaluation portion 74, calculates the elapsed time evaluation of estimate as the summation of these values.
Have again, as shown in Figure 21, carried out the user under the situation of input operation, owing to after selecting channel B in 21: 01, do not carry out the selection of channel, so from program start time, the i.e. program of audiovisual Figure 20 " news 4 " between 23: 00 28 minutes of assigning to till the input operation that 23: 28 users carry out power-off.Like this, under program begins to advance the situation of selection in line frequency road, the part audiovisual time period begins to count from program the zero hour, finishes under the situation of selection of its channel of laggard Xingqi at program on the contrary, is decided to be program finish time the finish time of part audiovisual time period.
On the other hand, with respect to the part audiovisual time period, the time of having selected to play after the channel of this program to till the broadcast that begins program is called " the part audiovisual begins the preceding elapsed time ".For example, under the situation of " news 4 ", have 119 minutes owing to assign to 23: 00 of beginning program from 21: 01 of the channel B that selected broadcast program, the elapsed time was 119 minutes before the part audiovisual of this moment began.In addition, in 2 part audiovisual time period the bests of " epoch play 2 ".Owing to when having selected channel B, begun broadcast, it under any circumstance all is 0 minute so the part audiovisual begins the preceding elapsed time.
Figure 23 is illustrated in the figure that elapsed time table of reference during evaluation of estimate is calculated by program attention rate evaluation portion 74.Must prepare this table in advance in the inside of program attention rate evaluation portion 74.In Figure 23, the length of longitudinal direction (line direction) expression part audiovisual time period, the audiovisual of transverse direction (column direction) expression part begins the preceding elapsed time.In the left hurdle of this table, be constant establishing t and s, when establishing r and being variable, [t, s] expression scope t≤r≤s, [t, s) expression scope t≤r＜s, (t, s] expression scope t＜r≤s, (t, s) expression scope t＜r＜s, [t, ∞) expression scope t≤r, (t, ∞) expression scope t＜r.Having, also is same afterwards among the figure of other of reference again.Numeric representation in Figure 23 in the hurdle separately of the usefulness longitudinal axis and transverse axis appointment is with respect to the part audiovisual time period evaluation of estimate of this part audiovisual time period.
According to Figure 23, for example under the situation of program " news 4 ", the part audiovisual time period has only 1 because length is 28 minutes, so be equivalent to [20,30) scope because the part audiovisual begin before the elapsed time be 119 minutes, so be equivalent to [61, scope ∞).Thereby, if with reference to the longitudinal axis be [20,30) the hurdle, transverse axis be [61, hurdle ∞), then part audiovisual time period evaluation of estimate is 9 as can be known.Moreover, as narrating, because the elapsed time evaluation of estimate of program is the summation of part audiovisual time period evaluation of estimate, so the elapsed time evaluation of estimate of program " news 4 " is 9.In addition, under the situation of program " epoch play 2 ", the part audiovisual time period has 2, and which length all is 7 minutes, and the elapsed time was 0 minute before the part audiovisual began.Thereby, if with reference to the longitudinal axis be [1,10) the hurdle, transverse axis be [0,10) the hurdle, then which part audiovisual time period evaluation of estimate all be 4 for as can be known.Thereby the elapsed time evaluation of estimate of " epoch play 2 " adds up to 8.
But, Figure 23 shows part audiovisual time period evaluation of estimate can begin as the length of part audiovisual time period and part audiovisual before 2 variable functions in elapsed time situation about calculating.In Figure 23, if with respect to separately row be conceived to than [11,30) on the right side part, then turn right more as can be known, value diminishes more.For example, at the longitudinal axis be [1,10) row in, the value of transverse axis be [11,30) time be 10, [31,60) time be 6, [60, be 3 in the time of ∞), turn right and more reduce.Thereby, before the part audiovisual begins the elapsed time than in the 11 big scopes, part audiovisual time period evaluation of estimate for the part audiovisual begin before the minimizing function in elapsed time.Have, the elapsed time evaluation of estimate is calculated as the summation of part audiovisual time period evaluation of estimate again.Thereby, with respect to the part audiovisual time period separately, before the part audiovisual begins the elapsed time than in the 11 big scopes, the elapsed time evaluation of estimate for the part audiovisual begin before the minimizing function in elapsed time.
Figure 24 is the figure that the example of the elapsed time evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.In Figure 24, in user's program names of the program of audiovisual in fact shown in the 1st row, in the part audiovisual time period of each program shown in the 2nd row, begin the preceding elapsed time in part audiovisual shown in the 3rd row, in part audiovisual time period evaluation of estimate shown in the 4th row, in elapsed time evaluation of estimate shown in the 5th row.For example, under the situation of " epoch play 2 ", as narrating, be respectively 4 with respect to the part audiovisual time period evaluation of estimate of part audiovisual time period of 2 existence, the elapsed time evaluation of estimate adds up to 8.Have again, shown in Figure 20 and in Figure 24 unshowned program be the once also nonoptional program of user.The elapsed time evaluation of estimate of each program of this moment is 0.
Like this, because with the index of elapsed time evaluation of estimate, so can carry out the recommendation of the higher program of accuracy as evaluation program attention rate.Secondly, volume operation frequency evaluation of estimate is described.
The user carries out the input operation this point and has got rid of the possibility of user not in the portion of televising, before being TV.Particularly never carry out the selection operation of frequency and carry out volume adjustment operation this point and can infer easily that the user pays close attention to this situation of program in the broadcast.Therefore, by estimating the frequency of the volume adjustment operation in the playing programs, can more correctly estimate user's program attention rate.Under the situation of volume operation frequency evaluation of estimate, the frequency of volume adjustment operation is calculated as increasing function, can carry out the higher information recommendation of accuracy.
74 pairs in program attention rate evaluation portion notifies the number of times of user's volume incident to count from operation inputting part 71, with the interval every 1 hour the volume incident is calculated as " volume operation frequency "." volume operation frequency evaluation of estimate " also calculated from this volume operation frequency by program attention rate evaluation portion 74.It is same that volume operation frequency evaluation of estimate and volume are operated frequency, with respect to calculating every 1 hour interval.
Figure 25 is the figure that the example of the volume operation frequency that program attention rate evaluation portion 74 calculates is shown.The left hurdle of table shown in Figure 25 represents that every 1 hour time period volume operation frequency is represented on right hurdle.For example, in the example of Figure 21,, notify the volume incident of 00 minute, 08 minute, 10 minutes, 40 minutes, 45 subtotalings 5 times from 19: 00 to 20: 00 time period.Thereby in Figure 25, from 19: 00 to 20: 00 time period, volume operation frequency is 5.
Figure 26 is the figure of the table of reference when the volume operation frequency evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.Must prepare this table in advance in the inside of program attention rate evaluation portion 74.In Figure 26, up is volume operation frequency, and descending is volume operation frequency evaluation of estimate.Can find out obviously that in Figure 26 volume operation frequency evaluation of estimate is the increase function of volume operation frequency.
Figure 27 is the figure that the example of the volume operation frequency evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.The left hurdle of table shown in Figure 27 represents that every 1 hour time period volume operation frequency evaluation of estimate is represented on right hurdle.According to Figure 25 because the volume from 19: 00 to 20: 00 time period operation frequency is 5, so be equivalent to Figure 26 [4,6) scope, it is 4 that volume is operated the frequency evaluation of estimate.Thereby, be 4 corresponding to the hurdle of Figure 27 " 19:00-20:00 ".
Like this, because volume is operated the frequency evaluation of estimate as an index estimating the program attention rate, so can carry out the recommendation of the higher program of accuracy.Secondly, illustrate apart from evaluation of estimate.
In the present embodiment, be provided with that range determination portion 77 measures the user and the distance between the portion 73 of televising.Under the little situation of Determination of distance value, be near the situation of user TV, can infer that the user is paying close attention to program.Thereby, according to the Determination of distance value, can more correctly estimate user's program attention rate.Under the situation of distance evaluation of estimate,, can carry out the high information recommendation of accuracy by with the time averaging minimizing function of program attention rate as the user and the distance between the portion 73 of televising.
Program attention rate evaluation portion 74 as shown in figure 22, calculating apart from time average every 1 hour interval, but program attention rate evaluation portion 74 also calculates " apart from evaluation of estimate " from this apart from time average.Apart from evaluation of estimate with identical, with respect to every 1 hour interval and calculate apart from time average.
Figure 28 be illustrate that program attention rate evaluation portion 74 calculates apart from evaluation of estimate the time reference the figure of table.Must prepare this table in advance in the inside of program attention rate evaluation portion 74.In Figure 28, up is apart from time average, and descending is apart from evaluation of estimate.Can obviously find out in Figure 28, be minimizing function apart from time average apart from evaluation of estimate.
Figure 29 is the figure apart from the example of evaluation of estimate that illustrates that program attention rate evaluation portion 74 calculates.According to Figure 22 because from 19: 00 to 20: 00 time period, be 3 meters apart from time average, so be equivalent to Figure 28 [2,4) scope, be 2 apart from evaluation of estimate.Thereby, be 2 corresponding to the hurdle of Figure 29 " 19:00-20:00 ".
Like this, because will be apart from evaluation of estimate as an index estimating the program attention rate, so can carry out the recommendation of the higher program of accuracy.Secondly, the volume evaluation of estimate is described.
From the portion of televising 73 relevant volume is relatively set under the condition with higher, the user plan to listen to well sound etc. situation, be that possibility is very high, can infer easily that the user is paying close attention to program.Thereby, if according to the volume of operating, can more correctly estimate user's program attention rate according to user's adjustment.Under the situation of volume evaluation of estimate,, can carry out the higher information recommendation of accuracy by the program attention rate is calculated as the time averaging increase function of volume.Program attention rate evaluation portion 74 uses from the volume incident of operation inputting part 71 notices, to obtain the maximal value and the minimum value of volume (volume value) every 1 hour interval, on average calculates as " volume intermediate value " with it." volume evaluation of estimate " also calculated from this volume intermediate value by program attention rate evaluation portion 74.The volume evaluation of estimate is identical with " volume intermediate value ", with respect to calculating every 1 hour interval.
Figure 30 is the figure that the example of the volume intermediate value that program attention rate evaluation portion 74 calculates is shown.The left hurdle of table shown in Figure 30 represents that every 1 hour time period, the volume intermediate value was represented on right hurdle.In Figure 21, for example between 20: 00 to 21: 00 time, the volume incident only took place 1 time at 20: 01, and this volume value is 14.Wherein, because the volume incident of volume value 18 took place at 19: 45, so the maximal value of the volume value in this 1 hour is 18, minimum value is 14.Thereby, the volume intermediate value in this time period be each value average, promptly 16, represent as shown in Figure 30.Can consider that the volume intermediate value is the time averaging a kind of of volume value.
Have, under the power remove state, volume value is 0 again.Thereby from 18: 00 to 19: 00 1 hour, the maximal value of volume value is 10, and minimum value is 0, and the volume intermediate value is 5 as shown in figure 30 like that.
Figure 31 is the figure of the table of reference when the volume evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.Must prepare this table in advance in the inside of program attention rate evaluation portion 74.In Figure 31, up is the volume intermediate value, and descending is the volume evaluation of estimate.Have, in the present embodiment, the maximal value of supposing volume value is 30 again.Thereby in Figure 31, the volume intermediate value illustrates to be up to 30 scope.Can find out obviously that in Figure 31 the volume evaluation of estimate is the increase function of volume intermediate value.
Figure 32 is the figure that the example of the volume evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.According to Figure 30, because the volume intermediate value from 19: 00 to 20: 00 time period is 19, so be equivalent to the scope of Figure 31 [18,30], the volume evaluation of estimate is 6.Thereby, be 6 corresponding to the hurdle of Figure 32 " 19:00-20:00 ".
Like this, because with the index of volume evaluation of estimate, so can carry out the recommendation of the higher program of accuracy as evaluation program attention rate.Secondly, description time section evaluation of estimate.
The user plays the selection operation of the channel of this program when planning certain program of audiovisual.If the degree of concern of program of audiovisual is bigger to planning, then should be according to the broadcast program table, from the moment of the broadcast that begins this program, select to play the channel of this program.That is, time period of the channel selection undertaken by user operation broadcast program with according to the high situation of the consistent degree of the reproduction time section of this program of reproduction time table under, can infer that the user is paying close attention to this program.Thereby, can more correctly estimate user's program attention rate according to the consistent degree of such time period.Under the situation of time period evaluation of estimate,, can carry out the higher information recommendation of accuracy by the program attention rate is calculated as the increase function of the degree consistent with the time period.
" time period unanimity degree " for user's part audiovisual time period of the program of audiovisual in fact, calculated respectively by program attention rate evaluation portion 74.Whether the reproduction time section of time period unanimity degree program is consistent with the time period of in fact audiovisual." the time period evaluation of estimate " of this program also calculated by program attention rate evaluation portion 74 from this time period unanimity degree.
Program attention rate evaluation portion 74 at first obtains " representing the time period " for this program when calculating " time period unanimity degree ".Representing the time period is time period the earliest in part audiovisual time period of this program.But, for the selection that begins to carry out in the past channel at this program and under the situation that the part audiovisual time period is counted from program the zero hour, be not the program zero hour zero hour of representing the time period, but will pass up to the moment of the selection of carrying out channel.Equally, after the end of this program for the selection of carrying out channel or power remove and become under the program situation of the finish time finish time of part audiovisual time period, be not the program finish time finish time of representing the time period, but be decided to be the selection of carrying out channel or the moment of power remove.Obtain represent the time period after, program attention rate evaluation portion 74 usefulness following formulas are calculated time period unanimity degree.
(time period unanimity degree)=min ([20/ (representing poor+1 of the zero hour and the program zero hour of time period)], [20/ (representing poor+1 of the finish time and the program finish time of time period)])
In the formula, " [", "] " expression Gauss symbol, [N] is the maximum integer that is no more than N.In addition, (X, Y) expression is decided to be output valve with the little value among X and the Y to min.Time period unanimity degree all is to get big value under the situation of approaching value in the zero hour that is only limited to the reproduction time section of representing time period and program and the finish time.Thereby time period unanimity degree is the value that whether approaches time period of being illustrated in audiovisual material under the situation that does not change channel the reproduction time section of program.
Figure 33 is the figure that the example of the time period unanimity degree that program attention rate evaluation portion 74 calculates is shown.In Figure 33, the in fact program names of the program of audiovisual of user is shown in the 1st tabulation, and the representative time period of this program is shown in the 2nd tabulation, and time period unanimity degree is shown in the 3rd tabulation.For example, in Figure 24, the part audiovisual time period of " TV play 1 " is from 19: 00 to 20: 00, and as can be known from Fig. 21, having selected the moment of the channel A of broadcast " TV play 1 " is 18: 59, is before the broadcast of " TV play 1 " begins.In addition, having selected moment beyond the channel A is after the broadcast of " TV play 1 " finishes 20: 05.Thereby in Figure 33, the representative time period of " TV play 1 " is " 18:59-20:05 ".Thereby (representing poor+1 of the zero hour and the program zero hour of time period) is the 1[branch]+1=2, X=10.In addition, (representing poor+1 of the finish time and the program finish time of time period) is the 5[branch]+1=6, Y=3.Thereby the time period unanimity degree of " TV play 1 " is a side of little value, promptly 3.Have, unshowned program is the in fact program of not audiovisual of user in the table of Figure 33 again, and the time period unanimity degree of these programs is 0.
Figure 34 is the figure of time period table of reference during evaluation of estimate of illustrating that program attention rate evaluation portion 74 calculates.Must prepare this table in advance in the inside of program attention rate evaluation portion 74.In Figure 34, up is time period unanimity degree, and descending is the time period evaluation of estimate.Can find out obviously that in Figure 34 the time period evaluation of estimate is the increase function of time period unanimity degree.
Figure 35 is the figure that the example of the time period evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.According to Figure 33 because the time period unanimity degree of " TV play 1 " is 3, so be equivalent to Figure 34 (2,6] scope, the time period evaluation of estimate is 4.Thereby, be 4 corresponding to the hurdle of Figure 35 " TV play 1 ".
Like this, because with the index of time period evaluation of estimate, so can carry out the recommendation of the higher program of accuracy as evaluation program attention rate.At last, channel selection frequency evaluation of estimate is described.
The high situation of frequency that the user changes channel is that the user seeks oneself interesting program, changes the situation of the so-called remote control channel selection of frequency continually.Under the situation that does not have audiovisual than the broadcast of certain channel of long time, the user does not only pay close attention to the possibility height of the specific program of having play.That is, can infer that this situation is just at the some programs of audiovisual, but the situation that any program is all not too paid close attention to.Thereby, according to the frequency of the channel selection operation of being undertaken by the user, can more correctly estimate user's program attention rate.Under the situation of channel selection frequency evaluation of estimate, calculate by the minimizing function that the program attention rate is changed the frequency of channel as the user, can carry out the higher information recommendation of accuracy.
74 pairs of number of times from the channel incident of operation inputting part 71 notices of program attention rate evaluation portion are counted, and with the interval every 1 hour the number of times of channel incident are calculated as " channel selection frequency "." channel selection frequency evaluation of estimate " also calculated from this channel selection frequency by program attention rate evaluation portion 74.Channel selection frequency evaluation of estimate is the same with the channel selection frequency, with respect to every 1 hour interval and calculate.
Figure 36 is the figure that the example of the channel selection frequency that program attention rate evaluation portion 74 calculates is shown.The left hurdle of table shown in Figure 36 represents that every 1 hour time period, the channel selection frequency was represented on right hurdle.In Figure 21, for example, notify 8 times channel incident between 20: 00 to 21: 00 time period.Thereby in Figure 36, at the same time, the channel selection frequency is 8.
Figure 37 is the figure of the table of reference when the channel selection frequency evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.Must prepare this table in advance in the inside of program attention rate evaluation portion 74.In Figure 37, up is the channel alteration frequency, and descending is channel alteration frequency evaluation of estimate.Can find out obviously that in Figure 37 channel alteration frequency evaluation of estimate is the minimizing function of channel alteration frequency.
Figure 38 is the figure that the example of the channel selection frequency evaluation of estimate that program attention rate evaluation portion 74 calculates is shown.The left hurdle of table shown in Figure 38 represents that every 1 hour time period channel selection frequency evaluation of estimate is represented on right hurdle.According to Figure 36 because for example the channel selection frequency from 20: 00 to 21: 00 time period is 8, so be equivalent to Figure 37 (6, ∞] scope, channel selection frequency evaluation of estimate is-6.Thereby, be-6 corresponding to the hurdle of Figure 38 " 20:00-21:00 ".
As mentioned above, program attention rate evaluation portion 74 calculate elapsed time evaluation of estimate, volume operation frequency evaluation of estimate, apart from evaluation of estimate, volume evaluation of estimate, time period evaluation of estimate and channel selection frequency evaluation of estimate.The summation of program attention rate as these values calculated by program attention rate evaluation portion 74.
Have again, in above-mentioned example, volume operation frequency evaluation of estimate, apart from evaluation of estimate, volume evaluation of estimate and channel selection frequency evaluation of estimate not for program but for calculating every 1 hour interval.These values with respect to each program are decided to be the value of playing programs in the time period under in fact the user carries out the situation of audiovisual, in fact do not carry out the user being decided to be zero under the situation of audiovisual.For example, in Figure 32, be 6 from the volume evaluation of estimate of 19: 00 to 20: 00 time period.Thereby, play at the same time, the user in fact the volume evaluation of estimate of " TV play 1 " of audiovisual be 6.In contrast, though in fact not have the volume evaluation of estimate of " intellectual check 1 " of audiovisual be 0 playing the user at the same time.
As mentioned above, elapsed time is than in the 11 big scopes before the part audiovisual begins, the elapsed time evaluation of estimate is the minimizing function in elapsed time before the part audiovisual begins, volume operation frequency evaluation of estimate is the increase function of volume operation frequency, apart from evaluation of estimate is minimizing function apart from time average, the volume evaluation of estimate is the increase function of volume intermediate value, and the time period evaluation of estimate is the increase function of time period unanimity degree, and channel alteration frequency evaluation of estimate is the minimizing function of channel alteration frequency.Because the program attention rate is the summation of these values, intactly inherit these character.Promptly, the program attention rate before the part audiovisual begins the elapsed time than in the 11 big scopes, it is the minimizing function in elapsed time before the part audiovisual begins, it is the increase function of volume operation frequency, minimizing function apart from time average, being the increase function of volume intermediate value, is the increase function of time period unanimity degree, is the minimizing function of channel alteration frequency.
Figure 39 is the figure that the example of the program attention rate that program attention rate evaluation portion 74 calculates is shown.In Figure 39, channel name is shown in the 1st tabulation, program names is shown in the 2nd tabulation, the elapsed time evaluation of estimate is shown in the 3rd tabulation, and volume operation frequency evaluation of estimate is shown in the 4th tabulation, and the 5th tabulation is shown apart from evaluation of estimate, the volume evaluation of estimate is shown in the 6th tabulation, the time period evaluation of estimate is shown in the 7th tabulation, and channel selection frequency evaluation of estimate is shown in the 8th tabulation, and the program attention rate is shown in the 9th tabulation.In Figure 39, the part on empty hurdle is the evaluation of estimate that does not in fact have audiovisual for the user, is 0.
In Figure 39, because for example the elapsed time evaluation of estimate of " TV play 1 " is 45, volume operation frequency evaluation of estimate is 4, apart from evaluation of estimate be 2, the volume evaluation of estimate is 6, the time period evaluation of estimate be 4 and channel selection frequency evaluation of estimate be 0, so the program attention rate is the summation of these values, promptly 61.
Figure 40 is the figure that the content example of the record information of storage in the record information storage part 76 is shown.The information of the relevant program attention rate of calculating in the above described manner only is shown in Figure 40, the information such as access resume according to other input operation are not shown.The content of the record information in Figure 40 is the content before the program shown in broadcast Figure 20.The cusum of the program attention rate that record information comprises the program names of the program of playing in the past, estimate so far for each program, be the broadcasting time up to now of program attention rate summation and each program.For example, have the program of the program names of " news 1 ", play up to now 5 times, the cusum of program attention rate up to now is 8.Have, in Figure 40, only showing for explanation is necessary part again.In addition, about " golf 1 ", " golf 2 ", " film 1 ", " film 2 ", be the once also nonoptional program of user up to now.Thereby, in Figure 40, there is not corresponding row.Program attention rate evaluation portion 74 is reflected in the record information storage part 75 the program attention rate of each program of newly calculating as described above.
Figure 41 illustrates the figure that makes the program attention rate of newly calculating be reflected in the content example of the record information behind the record information shown in Figure 40.For example, in Figure 39 because the program attention rate of having calculated " TV play 1 " is 61, thus in Figure 40 itself be the program attention rate summation of 20 " TV play 1 " be updated to 81 shown in Figure 41 (=20+61).In addition, in Figure 40 itself be 1 broadcasting time in Figure 41 through additive operation and become 2.
Have, the program with respect to not corresponding with up to now record information project makes new project again.In Figure 41, make " golf 1 ", " golf 2 ", " film 1 ", " film 2 " projects.
But programme information recommendation portion 76 accepted the listing information of relevant this program before playing new program from the information source 72 of televising.Reply user recommend programs is selected with reference to record information by programme information recommendation portion 76 from listing information.
Figure 42 is the figure that the content example of the listing information of new notice from the programme information source is shown.The form of the listing information shown in Figure 42 is identical with Figure 20.The listing information of Figure 42 is decided to be the information of playing the program information source notice after 1 week afterwards of the program shown in Figure 20.If compare with Figure 20, then " golf 1 ", " golf of playing in the past 2 " and " film 1 ", the time period of " film 2 " are predefined for broadcast " baseball 1 ", " baseball 2 ", " film 3 " and " film 4 ".
Programme information recommendation portion 76 is retrieved from record information, utilizes following formula to calculate the project of each program that is equivalent to listing information.
(recommendation evaluation of estimate)=[(program attention rate summation)/(broadcasting time)]
In the formula, under situation about not seeing corresponding to the project of record information, recommending the value of evaluation of estimate is 0.
Figure 43 is the figure that the example of the recommendation evaluation of estimate that programme information recommendation portion 76 calculates is shown.For example, in Figure 41, because the program attention rate summation of " TV play 1 " is 81, broadcasting time is 2, by with these value substitution following formulas, can obtain the recommendation evaluation of estimate 40 of " TV play 1 " shown in Figure 43.
The program of recommending evaluation of estimate pre-set threshold (for example 20) is selected to surpass by programme information recommendation portion 76, by showing in the portion of televising the user is recommended this program.In Figure 43, because the recommendation evaluation of estimate of " TV play 1 " and " TV play 2 " surpasses threshold value, so recommend these programs.The picture to the portion of televising 73 when programme information recommendation shown in Figure 44 portion 76 is programs recommended shows example.
So, programme information recommendation portion 76 carries out the recommendation of program according to the content that program attention rate evaluation portion 74 estimates.In this embodiment, recommended TV series, but also be effective the sports cast play aperiodically etc.In addition, if carry out the information recommendation that interrelates with the key word shown in the embodiment 1, then for example also can be recommended in other program of performer's of performance predetermined performance in " TV play 1 " and " TV play 2 " or this performer as predetermined certain CD sold of singer etc.The higher information recommendation of accuracy that so, can add user's degree of concern.
In the present embodiment, utilize the structure of following formula, carry out the recommendation of information by predefined value and calculation method again, but this is an example, the invention is not restricted to these settings and condition.The part of application examples below is shown.
Range determination portion 77 has measured the user and the distance between the portion 73 of televising, but but also serviceability temperature sensor, only judge user's existence, be not with distance notice program attention rate evaluation portion 74 but whether notify program attention rate evaluation portion 74 user's existence.
The volume intermediate value has been calculated by program attention rate evaluation portion 74, but also can use the time average of volume value.Moreover, as mentioned above, also can count the volume incident that makes the volume increase and decrease, replace the index of volume as evaluation object.This does not comprise the information of absolute volume value in incoming event particularly, relatively adjusting under the situation of volume value of the portion 73 that televises up and down as benchmark with present value is effective.
