Abstract
A recommended program extraction device holds a correspondence table between program attributes and keywords. If recording history information is present (S102), a point table correlating a point to the program attribute (broadcast time band, genre, etc.) is created according to the recording history information (S107). When the genre of a program to be broadcast is a predetermined one (for example, ''others''), it is judged whether the program information on the broadcast program contains a keyword. If a keyword is contained, the genre of the broadcast program is modified according to the correspondence table (S113). By using the point table, a total of the points corresponding to the program attributes is calculated for each of the programs to be broadcast (S114, S115). According the calculated total value of the points, a recommended broadcast program is extracted (S116).

Action to recommended program extraction device 1 describes below.At first the situation of using 1 pair of program of recommended program extraction device to record a video is described.About the subscription information of the program of recording a video, set and be recorded in the nonvolatile memory 19.Usually, in the recommended program extraction device 1 of holding state, when near the video recording of preserved program during the zero hour (when for example waiting before 3 minutes in video recording zero hour), the systems control division 22 that starting sets, so that start timer in advance, and then to various modules (encoder/decoder control part 21, recording schedule portion 28, whole module such as display system control part 23 grades) and various inscape (mpeg encoder 7, mpeg decoder 14, whole key elements in HDD 12 recommended program extraction devices such as grade 1) send indication and start, and then encoder/decoder control part 21 is indicated and made mpeg encoder 7 be in the video recording holding state.When arriving video recording during the zero hour, the broadcast ripple that is received by antenna 2 is tuned in the channel of preserved program by TV harmony device 5, takes out video and audio-frequency information.And then A/D converter 6 for example is converted to digital video signal according to Rec656 standard etc. with analog video signal.7 pairs of digital video signals of mpeg encoder carry out the MPEG compression.Bit stream by mpeg encoder 7 outputs is stored in record with in the buffer 8 temporarily, and writes among the HDD 12 of HDD controller 11 controls according to the order of storage.
Reproducing movement to recommended program extraction device 1 describes below.User's remote controller 3 (operating portion of perhaps not shown main body) for example is shown in the guide look that is recorded in the program among the HDD 12 on the monitor 4.The user selects the program of hope from shown program guide look, send the indication of reproducing.These are for example handled by being received infrared ray or the electric wave signal that sends from remote controller 3 by remote controller I/F 16 and sending its command context to CPU 10 and carry out.The program that CPU 10 will require to reproduce is read from HDD 12 via HDD controller 11, bit stream is stored in reads with in the buffer 15.Mpeg encoder 14 will be stored in the bit stream of reading with in the buffer 15 and read, and carry out the decoding processing of MPEG.Digital video signal through decoding processing synthesizes by OSD 18 and other character demonstration etc., and then makes digital video signal be converted to analog video signal by D/A converter 17, monitor 4 outputs to the outside, display video on monitor 4.
Adquisitiones to the EPG information of using recommended program extraction device 1 describes below.Here, the stacked data with EPG being added on situation about transmitting on the VBI of the specific channel of playing ripple describes.In the recommended program extraction device 1 that a TV harmony device 5 only is installed, when the video recording of the program of playing and audiovisual, use TV harmony device 5 sometimes, and can't receive the channel of the EPG that superposeed.Therefore, when for example holding state that the power supply of recommended program extraction device 1 seems to disconnect, receive EPG information.In addition, adopting EPG to receive the TV harmony device of establishing in addition outside the special use 5, under the situation of the method for a plurality of TV harmony devices 5 of perhaps in good time switching, even when recommended program extraction device 1 is in "on" position or action, also can receive the EPG data.
The recommended program extraction device 1 of execution mode 1 has only been installed a TV harmony device 5, therefore receives the EPG data under holding state.Now, recommended program extraction device 1 is in holding state, and is to carry out the time that EPG plays.The broadcast ripple of EPG of having superposeed is received by antenna 2, is tuned in the channel of the EPG that superposeed by TV harmony device 5, and limiter 9 extracts the processing of the EPG data on the VBI that is superimposed on vision signal.EPG data in the execution mode 1 are divided into less packet and transmit, and additionally in each grouping are useful on the packet ID that expression enters the information category in the grouping.In addition, the information that enters in the grouping is carried out encryption as required, and can arbitrarily not browsed or revise.In addition, each grouping also can be compressed processing for the packed data size.In EPG data parsing portion 20, the EPG data of having carried out above-mentioned processing are in time encrypted deciphering to be handled and decompression, described encryption deciphering is handled the packet parsing that has carried out according to the grouped data of each grouping kind classifying and the EPG data of encryption is understood, described decompression is to decompressing through the EPG of overcompression data, to revert to original EPG data.Above processing is undertaken by 20 pairs of EPG data of EPG data parsing portion, and is recorded in the volatile memory 13.
The EPG data that are recorded in the volatile memory 13 disappear when recommended program extraction device 1 outage, can't utilize the EPG data that are recorded in the volatile memory 13 when power supply starting next time.Therefore, be recorded in the record that the EPG data in the volatile memory 13 for example are used to back up in HDD 12 or nonvolatile memory 19.Backup is carried out after obtaining the EPG data and finishing data parsing.On the other hand, the EPG data of backup write the recovery processing of volatile memory 13 when power supply starting next time.The back-up processing of these EPG data and recovery are handled and are undertaken by EPG data backup portion 26.EPG data backup portion 26 is used to suppress the encryption that the compression of the data size of EPG data is handled and is used to improve secret in HDD 12 or nonvolatile memory 19 during the backup EPG data.In addition, EPG data backup portion 26 is as handling to the recovery of volatile memory 13 recovery EPG data from HDD 12 or nonvolatile memory 19, to carrying out decompression through the EPG of overcompression data and the EPG data that process is encrypted being carried out decoding processing.The EPG data that are recorded in the volatile memory 13 further launch to be treated to wieldy data mode by epg database 27.In addition, epg database 27 to recording schedule portion 28, systems control division 22, display system control part 23, program commending portion 29 as upper module, provides data content by API with the EPG data launched.The API that constructs that contains database in this API constructs API by calling this, and epg database 27 launches the EPG data in volatile memory 13.
Below the video recording record information that uses in recommended program extraction device 1 is described.In recommended program extraction device 1, the video recording resume in past are used for the recommendation of program as the data of expression user preferences.The video recording record information is information such as zero hour of program of title, channel, the video recording zero hour, video recording of the program of video recording in the past and the finish time, kind, impresario, coding parameter, when the video recording of program begins, foregoing is recorded in the nonvolatile memory 19.For the purpose of handling conveniently, the limited amount of video recording record information record for example keeps predetermined number amount (for example 1000) in order from up-to-date content.The video program information that surpasses predetermined number is according to order deletion from the old to the new.In addition, the number of video recording record information also can wait other conditions to limit according to video time (for example 1 year).
Fig. 3 is the flow chart of action (the perhaps recommended program extraction method of execution mode 1) of the recommended program extraction device 1 of expression execution mode 1.In execution mode 1, carry out programs recommended decision by software and handle.As shown in Figure 3, for example beginning (step S101) after the reception of EPG and dissection process of programs recommended extraction.In programs recommended extraction, at first carry out statistical disposition as the video recording record information of user's hobby data.Therefore, at first check whether there is video recording record information (step S102).Record information does not just show wrong content (step S118) if record a video, and (step S119) handled in the decision that end should recommend programs.If there is the video recording record information, then from the video recording record information, extract the information (step S103) of a program amount out, if can extract out then carries out the kind parsing (step S104) and the play start time section parsing (step S105) of the program of extracting out.In this is resolved,, make counting increase by 1 for the play start time section and the kind of unanimity.For example the zero hour of a program be 20:00 (constantly with " time: divide " mark, down together), if kind is " music ", then carry out following action: make the counting (point) of time period " 20:00～21:00 " add 1, and also make the counting of kind " music " add 1.To implementing this parsing operation as whole programs of video recording record information record.If finish statistical disposition, then to time period and kind additional sequence (step S106) to the whole programs in the video recording record information.For example shown in the some numerical table of Fig. 4, when the result of statistical disposition is, when the frequency of video program kind is confirmed as the 1st " TV play ", the 2nd " information please ", the 3rd " baseball ", the 4th " film ", the 5th " music " in proper order, give in advance they count be distributed as, promptly be assigned as the 1st 50 point, the 2nd 40 points, the 3rd 30 points, the 4th 20 points, the 5th 10 points.In addition, the reproduction time section is carried out statistical disposition similarly, and the 1st " 21:00～22:00 ", the 2nd " 22:00～23:00 " that is tried to achieve, the 3rd " 23:00～24:00 ", the 4th " 20:00～21:00 " and the 5th " 8:00～9:00 " waited each time period, the distribution of counting of giving in advance respectively promptly is assigned as the 1st 25 points, the 2nd 20 points, the 3rd 15 points, the 4th 10 points, the 5th 5 points respectively.In execution mode 1, when programs recommended, user's hobby is compared the influence that is subjected to kind more with the reproduction time section, makes the difference of counting to each order in the count distribution and the kind of kind become big.In addition,, used the play start time segment information, play the concluding time segment information, perhaps middle other information such as time period information constantly of reproduction time but also can adopt as the reproduction time segment information.
Beginning is according to EPG information and the extraction of recommend programs below.At first, confirm to exist the EPG information (step S108) of predetermined broadcast program in recommended program extraction device 1, if there is not EPG information just to show wrong (step S118), (step S119) handled in the decision that end should recommend programs.If in step S108, there is EPG information, then extract a program (step S109) out according to EPG information.The program of being extracted out is confirmed kind (step S110), if be not categorized into the kind (for example kind is the situation of " other " or predetermined content such as " not having corresponding ") of having a mind to, then the title or the details of programme information carried out keyword parsing (step S111).During the keyword that carries out in step S111 is resolved, kind and the keyword shown in the correspondence table of keyword that carries out as shown in Figure 5 carried out keyword and resolve,, then carry out the kind change if corresponding kind (step S112) is arranged.For example, if there is keyword " Major Leagues " in program detail information, then will classify changes to " baseball " in the kind of " other ".In addition, in keyword is resolved, in the time that keyword can't be detected, do not carry out the kind change.
Carry out the evaluation of the program extracted out below.In the evaluation of program, use some numerical table as shown in Figure 4.To the program of being extracted out, at first carry out the evaluation of kind, if there is the consistent kind of some numerical table with Fig. 4, then, the counting of kind of unanimity carried out add operation (step S114) as the counting of the program of extraction.And then, the program of extracting out is estimated, also the time period is estimated, if there is consistent time period of some numerical table with Fig. 4, then, the counting of time period of unanimity carried out add operation (step S115) as the counting of the program of extraction.These summations of counting become always the counting of program of extraction.
If the whole programs to the EPG data finish the step from step S109 to step S115 among Fig. 3, then extract out any amount obtained count and be upper program (step S116), in nonvolatile memory 19 with the program extracted out as programs recommended preservation (step S117), (step S119) handled in the decision that end should recommend programs.
By above-mentioned action extract out programs recommended, if for example push " program commending " button by user's remote controller 3, then transmit signal via remote controller I/F 16 to CPU 10 from remote controller 3, the programs recommended guide look of playback record in nonvolatile memory 19, this information is graphical by display system control part 23, and is shown on the monitor 4 via OSD 18.The user watches programs recommended guide look by monitor 4, can know programs recommended.In addition, the also device that can be constructed as follows: the user watches programs recommended guide look by monitor 4 on one side, highlight is moved in programs recommended guide look wait operation, and, can carry out recording schedule or audiovisual reservation by pushing operation such as decision button.And then the also device that can be constructed as follows: according to programs recommended guide look information, can automatically be the program of last figure place to the decision of counting, perhaps the above program of predetermined number of points carries out recording schedule or audiovisual is preengage.
The program that following illustration is concrete describes the situation that kind changes.A plurality of programme informations that expression is extracted out according to EPG in Fig. 6.In Fig. 6, at from last three programs " MLB Slam ", " arenas Friday " and " the Nature travel notes ", owing to be categorized into kind " baseball ", " TV play " and " record " of having had a mind to, therefore do not carry out the change (in the step S110 of Fig. 3, being judged to be "Yes") of kind.On the other hand, in Fig. 6,,, therefore the details among the EPG are carried out key search (the step S111 of Fig. 3) because kind is " nothing " at program " chance ".In the example of Fig. 6, in details, because keyword " information please " unanimity of kind " information please " shown in Figure 5, therefore be judged to be this program " chance " and be classified into kind " information please " (the step S112 of Fig. 3), the kind of this program " chance " in the EPG data is changed to " information please " (step S113 of Fig. 3).In addition, about program " incident ",, therefore the details among the EPG are carried out key search (the step S111 of Fig. 3) because kind also is " nothing ".In the example of Fig. 6, in details, keyword " script " unanimity of kind shown in Figure 5 " TV play ", therefore be judged to be this program " incident " and be classified into kind " TV play " (the step S112 of Fig. 3), the kind of this program " incident " in the EPG data is changed to " TV play " (step S113 of Fig. 3).
The evaluation result that the kind after changing of change kind, and use is like this carried out is shown in Fig. 7 (a).In addition, do not carry out the evaluation result of comparative example of kind change shown in Fig. 7 (b).Comparison according to Fig. 7 (a) and Fig. 7 (b) can be understood, and has following problem in Fig. 7 (b), promptly is classified in kind under the situation of " nothing ", is all step-downs of any programme content order.Relative therewith, in Fig. 7 that has changed kind (a), even for kind is program " incident " or " chance " of " nothing " originally, also can be considered as the kind consistent by key search with user's hobby, as a result of the order of recommend programs improves.
In the recommended program extraction device 1 that as above constitutes, user's video recording record information is carried out statistical disposition, owing to meet the program energetical recommendation more of user preferences, therefore can recommend to meet the program of user preferences.
In addition, since automatically programs recommended according to user's video recording record information and programme information, therefore can not cause operational burden to the user.
And then, the program that utilizes key search will be categorized into the kind of having a mind to reclassifies the kind that becomes to have a mind to, thereby because the reason (promptly not being the reason of user preferences) of the kind that program is had a mind to because of the unfiled one-tenth of EPG supplier, programs recommended candidate can be prevented to be difficult to become, the program of user preferences can be recommended to meet.
In addition, though in the above description, the situation of recommended program extraction device 1 for the recording apparatus of record television broadcast is illustrated, recommended program extraction device 1 also can be the recording device that receives and write down the radio broadcasting of following programme information.
Fig. 8 is the flow chart of action (the perhaps recommended program extraction method of execution mode 2) of the recommended program extraction device of expression embodiment of the present invention 2.In addition, Fig. 9 is the figure that is illustrated in the some numerical table that uses when programs recommended in the execution mode 2.The hardware configuration of the recommended program extraction device of execution mode 2 and software configuration, basic identical with the structure of the Fig. 1 that in execution mode 1, illustrates and Fig. 2.Therefore, in execution mode 2, also see figures.1.and.2.The computational methods of counting of the recommended program extraction device of execution mode 2 are different with the computational methods of counting of the recommended program extraction device of above-mentioned execution mode 1.Particularly, be with the difference of above-mentioned real-time mode 1: in execution mode 2, omitted the function that the classification of the program extracted out according to EPG information is changed, and appended in order to carry out the more detailed evaluation of program, to about the amount of information of program for example the number of characters of details estimate, also appended the evaluation of carrying out the time span of the reproduction time of program.
Processing from step S201 to step S208 shown in Figure 8 and is used to illustrate the shown in Figure 3 identical to the processing of step S108 from step S101 of execution mode 1.In the step S208 of Fig. 8,, then extract a program (step S209) out according to EPG information if in recommended program extraction device, there is EPG information.The program of being extracted out is carried out the evaluation (step S210) of kind,, counting of kind carried out add operation as about the counting of the program extracted out.Below the program of extracting out is carried out evaluation (step S211) about the time period,, obtain counting about the time period as about the counting of the program extracted out.And then, at the program of extracting out, the number of characters of the details of program is estimated (step S212) as amount of information, as about the counting of the program extracted out, to carrying out add operation about counting of amount of information.In addition, the program of extracting out is carried out evaluation (step S213) about the reproduction time length of program, as about the counting of the program extracted out, to carrying out add operation about counting of reproduction time length.
More than, if whole programs at the EPG data, finish step from step S209 to step S213, the aggregate value of counting that is obtained of then extracting any amount out is upper program (step S214), in nonvolatile memory 19 with the program extracted out as programs recommended preservation (step S215), finishes programs recommended decision processing (step S217).
Counting of the kind of Fig. 9 and time period is predefined value, to the key element of kind and the key element of time period, gives order by the statistical disposition of the video recording record information from step S203 to step S206.In execution mode 2, when programs recommended, user's hobby is subjected to having the greatest impact of kind, and is big to the difference change of counting of each order in the count distribution and the kind of kind.In addition, about time of playing also since the popularity or the qualitative difference of the program of playing according to the time period perhaps look the hearer and utilize the difference that also produces to a certain degree, thereby the distribution of counting and sequence difference are provided with poor.To " time span " or " amount of information ", be considered as lowlyer than " kind " or " time period " importance degree, will count and suppress for lower.In Fig. 9, the counting to make according to the record record information of " kind " or " time period " counted correspondingly with programme attribute, and the some numerical table of counting of " kind " or " time period " is called " the 2nd numerical table ".In addition, in Fig. 9, counting of " time span " or " amount of information " is predetermined counting, and also the some numerical table with " time span " or " amount of information " is called " the 1st numerical table ".In Fig. 9, make the minimum value of counting about the 2nd numerical table of " kind " or " time period ", bigger than the maximum of counting about the 1st numerical table of " time span " or " amount of information ".
Figure 10 is the figure that is illustrated in the programme information of being extracted out by EPG in the recommended program extraction device of execution mode 2.Here, the amount of information of Figure 10 obtains by the number of characters of the details of the EPG of record title of program and explanation etc. is counted.Figure 11 (a) is the programs recommended figure in the expression execution mode 2, and the result of the table for assessing of counting of Fig. 9 is used in expression to each program of Figure 10.Figure 11 (b) is the programs recommended figure of the comparative example of expression execution mode 2, has represented the situation that " time span " or " amount of information " estimated.
As among Figure 11 (b) as a comparative example shown in, in the evaluation of these three programs, under the situation that " time span " and " amount of information " estimated not, three programs are 150 identical counting, and can't tell the quality of these three programs on counting.Therefore exist because the sequential scheduling of the order of retrieval program or channel is not original assessment item and the possibility of additional sequence successively.But, shown in Figure 11 (a), by appending the assessment item of " time span " and " amount of information ", can be to the quality that three programs are additional on counting, the order that its result can clearly recommend.
As described below by the meaning that " time span " estimated.The first, the common program made especially of long program of time is owing to be the high program of cost of manufacture and the preservation of recording a video usually.The second, when the recording apparatus as the user uses, also,, therefore record a video usually for the audiovisual of carrying out regularly conversion so when live, be difficult to watch because long-time program is longer to the time of looking hearer's constraint.The 3rd, the program with the shorter reproduction time length about 5 minutes or 10 minutes, for example recording/viewing is seldom carried out in news or weather forecast or simple program introduction usually.Based on these reasons, the evaluation of " time span " is very meaningful as programs recommended assessment item.
In addition, " amount of information " about the details of EPG, mainly be meant the number of characters of details of the program of explanation of comprising program etc., it is higher that the more situation of character amount of these details is judged as being the possibility of program of the content with demand that the user desires.In addition, because the explanation that makes program also produces expense, also need the higher program of the value that to record a video of expense so can be evaluated as to be right separating of program.Like this, the project of " amount of information " also being judged as, is sufficient about the value of utilizing as programs recommended assessment item.
On the other hand, as shown in Figure 9, the project by " time span " and " amount of information " increases counting of counting and is 8 points to the maximum, lacks (in the example of Fig. 9 few one) than counting of estimating by kind or time period.This is that therefore in the recommendation of program, the influence of the project of " time span " or " amount of information " is less owing to when the user selects program, use " kind " or " time period " to select program usually than " time span " or " amount of information ".Therefore, by the quality of " time span " and " amount of information " additional program, do not act on and program is added good and bad occasion by kind or time period.But the also device that can be constructed as follows: making by " time span " or " amount of information " according to user's hobby etc. increases increases of counting of counting, and perhaps changes distribution.
In the programs recommended device of the execution mode 2 that as above constitutes, the order that is used for the video recording recommendation of program by the reproduction time length with program is added, and can recommend to have the program that video recording is worth.
In addition, the order that is used for the video recording recommendation of program by the amount of information with program is added, and can recommend the costly program of recording a video.
And then the order that is used for the video recording recommendation of program by the reproduction time length with program is added, and can will have the more special series of longer reproduction time, preferentially recommends as the program with video recording value.In addition, the order that is used for the video recording recommendation of program by the reproduction time length with program is added, and can will have the more program of shorter reproduction time, is worth lower program as video recording and does not recommend.In addition, owing to estimate the reproduction time length of program, so also can preferentially recommend to have the program of specific time span.
In addition, by estimating the amount of information of program, can preferentially recommend the more program of number of characters of title.
In addition, make according to below the maximum of counting that amount of information obtained of the reproduction time length of program or program the invocation point difference for the sequence difference of general assessment item such as " kind " or " time period ", thereby can be with general evaluation with the evaluation of deciding, and with the reproduction time length of program or amount of information with acting on the secondary stage evaluation of estimating.Promptly identical with " time period " to " kind " program can be by the recommendation degree of time span or amount of information judgement program.
In addition, also the recommended program extraction method of execution mode 2 can be combined in the recommended program extraction device or method of execution mode 1.
In addition, in execution mode 2, above-mentioned aspect in addition is identical with the situation of above-mentioned execution mode 1.
Figure 12 is the flow chart of action (the perhaps recommended program extraction method of execution mode 3) of the recommended program extraction device of expression embodiment of the present invention 3.In addition, Figure 13 is the figure that is illustrated in the some numerical table that uses in the recommended program extraction device of execution mode 3.The hardware configuration of the recommended program extraction device of execution mode 3 and software configuration, basic identical with the structure of the Fig. 1 that in execution mode 1, illustrates and Fig. 2.Therefore, in execution mode 3, also see figures.1.and.2.In addition, the computational methods of counting of the recommended program extraction device of execution mode 3 are different with the situation of the recommended program extraction device of above-mentioned execution mode 2.Particularly, be with the difference of execution mode 2, " time period " to the assessment item of program in execution mode 3 is further used as secondary assessment item and " kind " is set, and " time period " further is segmented and is " TV play ", " football " and " other (kind) ".
Below with reference to the flow chart of Figure 12, the action of the recommended program extraction device of execution mode 3 is described.Making in the step of a numerical table, the step S301 of Figure 12～S304 is identical with step S201～S204 of Fig. 8 of the explanation that is used for execution mode 2, and the step S301 of Figure 12～S304, S306, S307 step S201～S204, S206, the S207 with Fig. 8 of the explanation that is used for execution mode 2 respectively are identical.Making in the step of the some numerical table of execution mode 3, carry out the contents processing of the step S305 that the time period resolves according to each secondary assessment item (kind unit), different with the contents processing of the step S206 of execution mode 2.For example, if the program of extracting out from the video recording record information is " TV play ", be that unit carries out the statistical disposition about the time period then with " TV play ", and if the program of extracting out from EPG information is " football ", be that unit carries out the statistical disposition about the time period then with " football ".
In addition, about comprising the remaining step of the step that is used for programs recommended extraction, the step S308 of Figure 12～S310 is identical with step S208～S210 of Fig. 8 of the explanation that is used for execution mode 2, and the step S312 of Figure 12～S317 step S212～S217 with Fig. 8 of the explanation that is used for execution mode 2 respectively is identical.In the step that is used for programs recommended extraction of execution mode 3, carry out the count contents processing of step S311 of add operation of time period according to each secondary assessment item (kind unit), different with the contents processing of the step S211 of execution mode 2.For example, counting add operation (step S311) in the time period, is the add operation of counting that unit carries out the time period with " TV play " or " football " as the kind of secondary assessment item as shown in figure 13.
Be example with the program of extracting out below, the action in the execution mode 3 is described.Figure 14 is the figure that is illustrated in the programme information of being extracted out by EPG in the recommended program extraction device of execution mode 3.Figure 15 (a) is the programs recommended figure of expression in the execution mode 3, uses the some numerical table of Figure 13 to estimate to each program of Figure 14.Figure 15 (b) is the programs recommended figure of comparative example of expression execution mode 3, is secondary assessment item not to be set and the result that estimates.In addition, secondary assessment item is not set and the situation of carrying out with in Figure 15 (a) that the unified situation for " other " of secondary assessment item is identical.
In the method that secondary assessment item is not set of the comparative example of Figure 15 (b), the order that is categorized into kind is program " J football " and " Spain's football " of the 2nd " football ", because it is lower to obtain to count in the time period, so it is also lower to count aspect title.On the other hand, " place where Taoist rites are performed of making laughs " although the 4th of kind order is lower than " football ", because higher the counting of acquisition aspect " time period ", thereby compare with " Spain's football " with " J football ", it is higher to count.On the other hand, in the situation that secondary assessment item is set shown in Figure 15 (a), " J football " and " Spain's football " also can obtain higher counting in the evaluation of time period, and the result also can obtain higher counting aspect title.This is owing to make the time period difference of main broadcast according to kind, by having the order of time period at each kind, thereby can correctly carry out the evaluation of time period at each kind under the program.This means on the other hand, even the time period of often recording a video as general tendency, as long as in the kind under program is not the time period of often recording a video, also counting of obtaining can be suppressed for lower, and if kind and time period inconsistent then can't obtain higher counting.
On the other hand, in the comparison of " TV play A " and " reasoning mystery ", in the situation that secondary assessment item is not set, " the reasoning mystery " that 21:00 begins obtains higher counting, and draws back poor (Figure 15 (b)) at 9 with " TV play A ".But, the occasion of secondary assessment item is being set, in the evaluation of " time period " of " TV play ", given identical counting with the 2nd for the 1st, therefore aspect title, can obtain essentially identical counting (Figure 15 (a)).This be since the broadcast zero hour of main body that becomes TV play usually from 21:00 to 22:00, the program that program that 21:00 is begun and 22:00 begin not have intentionally poor in reality.On the other hand, the situation of playing TV play beyond this time period is less, and correspondingly the foundation that maybe should recommend of the chance of video recording also should be less as can be known, and is therefore lower about counting of the time period below the 3rd.
In execution mode 3, with " time period " and " kind " example as assessment item and secondary assessment item, but be not limited to time about the combination of assessment item and secondary assessment item, so long as the message form of handling in device can be other assessment item.
In the video recording fault program device of the execution mode 3 that as above constitutes, by secondary assessment item with the assessment item sectionalization, thereby can the further sectionalization of envoy's purpose evaluation, therefore can recommend more suitably to reflect the program of user preferences and entertaining.
In addition, owing to can change the distribution of counting, can be the poor in order maintenance meaning of unit therefore with secondary assessment item according to each secondary assessment item, the difference of envoy's purpose recommendation order is clear and definite, thereby can recommend to reflect more the program of user preferences and entertaining.
In addition, owing to can count according to two project decisions of assessment item and secondary assessment item, so the unfavorable condition that can prevent to recommend the higher program of a side.
In addition, also the recommended program extraction method of execution mode 3 can be combined in the recommended program extraction device or method of execution mode 1.
In addition, in execution mode 3, above-mentioned aspect in addition is identical with the situation of above-mentioned execution mode 1 or 2.
