R1=α 1 (number of times importance degree)+α 2 (importance degree at interval)+α 3 (length importance degree)+α 4 (reproduction speed importance degree)+α 5 (switching the number importance degree)

＝α1·1+α2·120+α3·20+α4·1+α5·1

Here, when establishing α 1=α 2=α 3=α 4=α 5,

R1＝143。

With same step, the importance degree R3 of the importance degree R2 of playback 2 and playback 3 is as follows.

R2＝1+105+15+1+1＝123

R3＝1+50+25+1+2＝79

30 pairs of each playback informations of playback importance degree computing unit are added the importance degree of obtaining like this and are made subsidiary importance degree playback information (figure), it is outputed to summary make unit 40.

Summary makes unit 40 in the combination of resetting, and selects the most approaching length by the appointment of summary conditional information, and importance degree and be the combination of maximum, make summary info (step 5).

Expression summary at this moment makes the detailed step in the unit 40 in Figure 12.Summary makes unit 40 and receives subsidiary importance degree playback information and summary conditional information (step 61), and whole playbacks is carried out following processing (step 62) as candidate's (after making summary, considering the key element of combination).

At first, judge whether the total time length of the playback of summary candidate has surpassed the length (step 63) of appointed summary.When exceeding, enumerate the combination (step 65) of the summary candidate of the length that all converges to appointed summary, summation (step 66) to each combination calculation playback importance degree of enumerating, the combination (step 67) of the playback of the summation maximum of selection playback importance degree, the playback of the combination selected is arranged according to time series, make summary info (step 68).And, in step 63, the playback of summary candidate total time length when not exceeding the length of appointed summary, be chosen in the whole playbacks (step S64) that comprise in the summary candidate, carry out the processing of step 68.

Under the situation of Fig. 5, in the time will being made as 40 seconds by the length of the summary of summary conditional information appointment, being combined as of playback " only resetting 1 " that converged to 40 seconds " only resets 2 " " only resetting 3 " " playback 1+ resets 2 " and " playback 2+ playback 3 " five, the summation of each playback importance degree is as described below.

" only reset 1 ": 143

" only reset 2 ": 123

" only reset 3 ": 79

" playback 1+ resets 2 ": 266

" playback 2+ resets 3 ": 211

Its result selects " the playback 1+ playback 2 " of the summation maximum of playback importance degree, these is reset arrange according to time series, makes summary info.

The output unit 50 output summaries of summary implementing device 10 make the summary info (step 6) that unit 40 makes.According to this summary info (Fig. 9), by from this broadcast video of accumulation, only show successively by the playback of video that rises the zero hour between the playback service area of summary info appointment till the finish time between the playback service area, can show the summary that is no more than appointed length.

Like this, in this summary creating method, can only utilize the information of the history (moment that Q beats, the handover information of switch etc.) of the broadcasting equipment that obtains easily, make the summary of designated length.

And, playback information also can be multiplexing in this broadcast video and provide, perhaps also can gather whole playback informations after end of match provides, or gather certain during in the playback of video that comprises playback information and provide termly.And, also can or look hearer's hobby, change importance degree calculated weighting coefficient according to the kind (sports cast, news program etc.) of broadcasting.

And in present embodiment 1, to the playback of using same broadcasting station to broadcast in same match, the situation that importance degree is calculated in the playback of promptly using in programme televised live is illustrated, but unnecessaryly only is limited to this.Sometimes also with reference to the playback of once using in other channel (comprising multichannel) or other match, for example, carry out reference with news program or sports cast etc.Under these circumstances, also can be to this additional importance degree of resetting.Thus, the playback of using in the program beyond the programme televised live can be used in summary.

And the summary implementing device of present embodiment 1 also can be arranged on the receiving terminal of receiving platform side, makes to look hearer's be used to make a summary summary info of audiovisual and use.And, also can be arranged in the central means of broadcasting station side, output is used for game content has been carried out the summary info that the summary program of summary makes.Perhaps, also can export and be used for the summary info that receiving terminal provided by broadcasting.In playback information and summary the obtaining of conditional information, can use " broadcasting " " distribution " " via network " etc.

And, also the part of functions piece of summary implementing device can be included in the central means, other functional block is included in the receiving terminal.For example, have playback importance degree computing unit 30 to be set in central means and to make a summary and make the situation of unit 40, perhaps playback importance degree computing unit 30 is arranged on central means, summary is made the situation that unit 40 is arranged on receiving terminal, perhaps playback importance degree computing unit 30 and summary are made unit 40 and be arranged on situations such as receiving terminal, can make the summary info of the summary conditional information that converges to setting in either event in central means side or receiving terminal side, and, can between two devices, share the load that summary makes processing, perhaps make the summary info of the hobby of also having considered the user etc.And, in central means, made under the situation of summary info, perhaps made under the situation of subsidiary importance degree playback information etc., both can in database (not shown), manage this each information, after also can between receiving terminal and central means, having carried out the communicating by letter of twocouese, obtain this each information of in database, managing.Thus, can between stream oriented device, make a summary expeditiously and make processing.

(the 2nd execution mode)

In the summary creating method in the 2nd execution mode of the present invention, will reset is taken in the summary with reference to interval nonoverlapping playback of video, thereby improves the quality of summary.

As shown in figure 14, inserted in this broadcast video under 1～4 the situation of resetting, if calculate importance degree, then " playback 1+ playback 2+ resets 3 " is than " playback 1+ playback 3+ resets 4 " height.But, " playback 1+ playback 2+ resets 3 " comprises " the resetting 1 " and " resetting 2 " of resetting with reference to interval repetition, on the other hand, " playback 1+ playback 3+ resets 4 " do not comprise the interval playback that repeats of the reference of resetting (promptly, the video of identical content), so " playback 1+ playback 3+ resets 4 " has more amount of information.Therefore, at this moment, by selecting " playback 1+ playback 3+ resets 4 ", the quality of summary improves.

Carry out the structure of the summary implementing device of this method and do not compare not variation with the 1st execution mode (Fig. 1, Fig. 6).Playback importance degree computing unit 30 calculates the importance degree that each is reset by the processing identical with the 1st execution mode, the playback information of attaching importance degree is outputed to summary make unit 40.

Summary makes unit 40 and makes summary info according to step shown in Figure 15.Summary makes unit 40 and receives subsidiary importance degree summary info and summary conditional information (step 61), and will all reset is considered as summary candidate (step 62), judges whether the total time length of the playback of summary candidate surpasses the length (step 63) of appointed summary.If when surpassing, then investigation is reset and is had or not the playback information (step 631) of repetition with reference to the interval, under the situation that has the playback that repeats, playback importance degree reckling is deleted (step 632) from summary candidate.

Processing afterwards is identical with the 1st execution mode, enumerate the combination (step 65) of the summary candidate of the summary length that all converges to appointment, summation (step 66) to each combination calculation playback importance degree of enumerating, the combination (step 67) of the playback of the summation maximum of selection playback importance degree, the playback of the combination selected is arranged according to time series, make summary info (step 68).And, in step 63, when the total time of all resetting, length did not all surpass the summary length of appointment, select all to reset (step 64), carry out the processing of step 68.

Treatment step when the length of making a summary under the situation of Figure 16 to Figure 14 is designated as 110 seconds carries out diagram.

The total time length of the playback in the time of (a) will all resetting as summary candidate was 160 seconds, above 110 seconds.

(b) therefore, detect the playback of resetting and repeating with reference to interval.Because the playback 1 and 2 repetitions of resetting are so the playback 2 of playback importance degree minimum is deleted from summary candidate.

(c) its result, summary candidate are reduced into and reset 1, reset 3, reset 4, its total time length be 120 seconds, surpass the length (110) second of appointment.

(d) therefore, (owing to not existing with reference to the interval playback that repeats) 4 is object to reset 1, to reset 3, reset, and enumerates being no more than 110 seconds combination, calculates the summation of playback importance degree.

(e) in this combination, the summation of importance degree is the highest one, be reset 3 combination of playback 1+.

(f) combination of selection playback 1+ playback 3 becomes final summary with playback 1, playback 3 according to the time series arrangement.

Like this, in present embodiment 2,, can improve the amount of information of summary by from resetting with reference to only selecting a summary candidate the interval overlapping playback.

(the 3rd execution mode)

In physical culture is live, repeatedly reset in highlight scene scene before this.In the summary creating method in the 3rd execution mode of the present invention, give high evaluation and the raising of the quality that realizes making a summary to this highlight scene.Highlight scene is the scene that the playback that will be considered to important in whole match is concentrated, and is reflected in during summary makes by the state that will be called highlight scene, and the quality of summary improves.

Figure 17 represents the different of highlight scene and common playback.Highlight scene is by continuous between the playback service area, and the interval unduplicated a plurality of playbacks of the reference of resetting constitute.Even continuous between the service area of a plurality of playbacks, but under their situation of playback with reference to the interval repetition, be common playback, not highlight scene.

The structure of device of carrying out this summary creating method is identical with the 1st execution mode (Fig. 1, Fig. 6).Just at playback importance degree computing unit 30 as one of viewpoint of the importance degree of metering playback informations, be conceived to highlight scene, and different for additional importance degree (highlight scene importance degree) this point of highlight scene.

Figure 18 has represented to comprise the treatment step of the summary implementing device 10 of processing that should playback importance degree computing unit 30.Playback importance degree computing unit 30 is for the playback information that sends from input unit 20, calculation times importance degree (step 2-1), at interval importance degree (step 2-2), length importance degree (step 2-3), reproduction speed importance degree (step 2-4) and number of handovers importance degree (step 2-5) time, reset continuously between the playback service area with reference under the interval unduplicated situation, their playback group is judged to be highlight scene, resets for each and set highlight scene importance degree (step 2-6).

Then, calculate the playback importance degree from calculation times importance degree, interval importance degree, length importance degree, reproduction speed importance degree, switching number importance degree and highlight scene importance degree, and to the additional (step 3) of playback information.Repeat such processing until whole playback informations are added playback importance degree (step 4).It is identical with the 1st execution mode that the summary that has received subsidiary importance degree playback information from playback importance degree computing unit 30 makes the action of unit 40.

Under the situation of playback shown in Figure 19 1～5, for each playback, except number of times, at interval, length, reproduction speed, switching number, judge also whether each playback is highlight scene.Though reset 1 and reset between 2 playback service areas continuously, reset with reference to interval repetition, so be not highlight scene.On the other hand, reset 3, reset 4 and reset between 5 playback service areas continuously, reset and do not repeat, so be judged as highlight scene with reference to the interval.Therefore, to reset 3, reset 4, reset 5 each reset and set highlight scene importance degree.If relatively reset 1 and 5 the importance degree of resetting, then the result is as follows.

Importance degree=number of times importance degree+interval importance degree+length importance degree+reproduction speed importance degree+switching number the importance degree of playback 1

＝1+60+40+1+1＝103

Importance degree=number of times importance degree+interval importance degree+length importance degree+reproduction speed importance degree+switching number importance degree+highlight scene the importance degree of playback 5

＝1+60+20+1+1+30＝113

Like this, in present embodiment 3,, the producer of program can be judged as important highlight scene video and be taken in the summary by improving the playback importance degree of the playback of video between the highlight scene service area.

(the 4th execution mode)

In the 4th execution mode of the present invention, the method for utilizing playback of video video in addition to make summary is described.In the method, obtain the information of the montage switching point of live video with playback information, as shown in figure 20, be substituted in and use playback of video in the summary, comprise the montage (that is the live video of the time of this playback of video of actual photographed band) of resetting and in summary, use with reference to interval live video.

The structure of summary implementing device of carrying out this method is identical with the 1st execution mode (Fig. 1, Fig. 6).Just different in the following areas, promptly in input unit 20, import the information of the montage switching point of the live video that the operation history by broadcasting equipment obtains with playback information, and summary makes in playback that unit 40 comprises from the subsidiary importance degree playback information information with reference to the information in interval and montage switching point determines to comprise the montage (a plurality of situation that contains is also arranged sometimes) of resetting with reference to interval live video, this montage is considered as adding the summary candidate of importance degree, has made summary info.

And, in input unit 20, given under the situation of scene information (information of representing the differentiation of significant video), can be substituted in the scene of using playback of video in the summary and in summary, using the live video that comprises the reference interval of resetting with playback information.

For example, as shown in figure 21, in baseball is live, at the scene information that the differentiation that is used for expression office is provided, the scene information and being used to that is used to represent striker's differentiation represents under the situation of scene information of differentiation of pitching, can will comprise the scene of the interval office of the reference of resetting as summary candidate, the scene that perhaps will comprise the interval striker of reference that resets is as summary candidate, and the scene that perhaps will comprise the interval pitching of reference of resetting is as summary candidate.And, can be as described as follows, when the importance degree of resetting is high, the scene of office is made as summary candidate, when the importance degree of resetting is low, the scene of pitching is set at summary candidate, change the size of the scene of differentiation according to the playback importance degree.

Figure 22 represents that at this moment summary makes the treatment step in the unit 40.If summary makes unit 40 and receives subsidiary importance degree playback information, summary conditional information and scene information (step 611), then vacate summary candidate and carry out following processing (step 612).Value by the importance degree reset, determining area is divided the level (step 614) of scene, utilize scene information, obtain the playback that includes playback interval (step 615) from appointed level, the interval of the scene that obtains is appended to (step 616) in the summary candidate with reference to the scene in interval.

Whole playbacks is repeated this processing, and when the correspondence of scene information being finished (step 613) for whole playbacks, judge whether the total time length in the scene interval of summary candidate surpasses the length (step 631) of appointed summary, under situation about surpassing, enumerate the combination (step 65) of the summary candidate of the length that all converges to appointed summary, for each combination of being enumerated, calculate the summation (step 66) of playback importance degree, the combination (step 67) of the summary candidate of the summation maximum of selection playback importance degree, the scene interval of the combination selected is arranged according to time series, make summary info (step 681).And, in step 631, whole scene intervals total time length when not surpassing the length of appointed summary, select whole scene intervals (step 641), carry out the processing of step 681.

Figure 23 and Figure 24 carry out diagram to processing at this moment.Unit (level) decision that the playback 1 that importance degree is high will be distinguished scene is " with the differentiation of office ", and the playback 2 that importance degree is low is " with the differentiation of pitching " with its decision, and the medium playback 3 of importance degree is " with striker's differentiation " with its decision.From scene information obtain comprise reset 1 with reference to interval " with the differentiation of office ", comprise reset 2 with reference to interval " with the differentiation of pitching ", comprise reset 3 with reference to interval " with striker's differentiation ", and with them as summary candidate.

Figure 24 (a1) represents the scene corresponding to the summary candidate of playback 1, and Figure 24 (a2) expression is corresponding to the scene of the summary candidate of playback 3, and Figure 24 (a3) expression is corresponding to the scene of the summary candidate of playback 2.

When the length of summary is designated as 160 seconds, use these three summary candidate to obtain whole combinations of the summary candidate that converges on 160 seconds, select the wherein combination of the summation maximum of importance degree.At this moment, select the combination shown in Figure 24 (b).In fact, utilize this summary info and by the summary of audiovisual shown in Figure 24 (c), become such with interval corresponding this broadcast video part (part of live 1) of the scene of " the 2nd innings of first half " and this broadcast video (parts of live telecast 3) corresponding with " striker 1 ".

Like this, in present embodiment 4, comprise the montage or the scene of resetting, understand the match of in playback of video, being shown easily and under which type of situation, take place, can improve the quality of summary with reference to this interval broadcast video by in summary, using.

And, though the differentiation of the time of scene can be used above-mentioned differentiation,, also can use this broadcast video video (video of other video camera beyond this broadcasting etc.) in addition as the video that summary uses.And,,, only utilize the interval of scene to make summary here though, make the interval corresponding of a scene for 1 playback, not necessarily be limited to this, interval two sides that also can make up playback, scene make summary.

(the 5th execution mode)

As by the explanation as can be known of above-mentioned execution mode, if the calculating of the importance degree of each playback information is roughly distinguished, then can be divided into two stages, at the number of times that has carried out resetting, at interval, after length, broadcasting speed or the montage of time switch the calculating of importance degree of number etc., carry out the calculating of the importance degree of this playback information.In the summary creating method in the 5th execution mode of the present invention, structure with the playback importance degree computing unit 30 shown in the execution mode 1 is divided into the 1st playback importance degree computing unit 31 and the 2nd playback importance degree computing unit 32, is divided into the method that receiving terminal 200 that central means 100 that the broadcasting station side has and receiving platform side have makes summary and describes.

As shown in figure 25, comprising: input unit 20, in central means 100, import the 1st playback information from editing equipment 70 and transducer 80 (Fig. 1); And the 1st playback importance degree computing unit 31, obtain the 1st playback information, and, make the 2nd playback information corresponding to each importance degree and the 1st playback information from this information calculations number of times importance degree, interval importance degree, length importance degree, reproduction speed importance degree, switching number importance degree etc.

Figure 26 represents to be input to the data structure of the 1st playback information of input unit 20.Discern the playback number that each is reset except being used in the 1st playback information, also comprise the finish time between the zero hour between the playback service area, playback service area, reset, reset with reference to the information of the interval finish time and photography video camera number with reference to the interval zero hour.And the 1st playback information of present embodiment is identical with the data structure of the playback information of representing in the 1st execution mode.

And Figure 27 represents the data structure of the 2nd playback information that made by the 1st playback importance degree computing unit 31.The 2nd playback information will from the number of times importance degree of each information calculations shown in the 1st playback information, at interval importance degree, length importance degree, reproduction speed importance degree, to switch number importance degree etc. corresponding with the 1st playback information.For example, under the situation of the playback 1 of Fig. 5, as shown in figure 11, the number of times importance degree is 1 (inferior), importance degree was 120 (seconds) at interval, and the length importance degree was 20 (seconds), and the reproduction speed importance degree is 1 (doubly speed), and to switch the number importance degree be 1 (inferior), and the 2nd playback information is corresponding with the 1st playback information with these each importance degrees.

On the other hand, have at receiving terminal 200: the 2nd playback importance degree computing unit 32, obtain the 2nd playback information of sending from central means 100, and according to the weight coefficient of composing storehouse 60 management of the regular setting data of power, thereby be adjusted at the importance degree that each importance degree of representing in the 2nd playback information calculates this playback information, the subsidiary importance degree playback information of output; The summary that makes summary info makes unit 40, and the summary conditional information (length of summary) of obtaining this subsidiary importance degree playback information and importing by user's operation is selected the high playback information of importance degree with the length coupling of making a summary; And the output unit 50 of exporting the summary info that is made to.And the 1st playback importance degree computing unit 31 of central means 100, the 2nd playback importance degree computing unit 32 of receiving terminal 200 and summary make unit 40 and realize by the put rules into practice program of action of the computer that is built in each device 100 or terminal 200.

Figure 29 is illustrated in and obtains the 1st playback information in the central means 100 and begin, the treatment step till the output summary info in receiving terminal 200.Input unit 20 in the central means 100 is obtained the 1st playback information (step 1).The 1st playback importance degree computing unit 31 is for the 1st playback information, even calculate importance degree (number of times importance degree) (step 2-1) with reference to the number of interval only some overlapping playback based on the viewpoint of " (a) playback number of times " from resetting, and, from the zero hour between the playback service area and the reference interval poor importance degree (importance degree at interval) (step 2-2) that calculates based on the viewpoint at " (b) between the playback service area and the interval in playback reference interval " of the zero hour of resetting, and, the poor importance degree (length importance degree) (step 2-3) that calculates based on the viewpoint of " (c) length of Chong Fanging " from the zero hour between the finish time between the playback service area and playback service area, and, poor from the zero hour between the finish time between the playback service area and playback service area, and reset and to calculate importance degree (reproduction speed importance degree) (step 2-4) based on the viewpoint of " (d) reproduction speed of Chong Fanging " with reference to the interval finish time and the ratio with reference to the difference of the interval zero hour reset, and, calculate importance degree (switching the number importance degree) (step 2-5) from the playback of playback information with reference to the quantity of the interval zero hour based on the viewpoint of " (e) number is switched in the montage between the playback service area ".

The 1st playback importance degree computing unit 31 repeats such processing, until whole playback informations being calculated each importance degree (step 3), under the situation that this processing has finished, the 2nd playback information is delivered to the 2nd playback importance degree computing unit 32 (step 4) of receiving terminal 200.

The 2nd playback importance degree computing unit 32 is obtained the 2nd playback information (step 5) of sending from the 1st playback importance degree computing unit 31 of central means 100.According to this information, the 2nd playback importance degree computing unit 32 is obtained from the regular setting data of tax power storehouse 60 regular setting table (Figure 30) is weighed in the tax of each kind management, according to the weight coefficient shown in this table, adjusts each importance degree shown in the 2nd playback information.

For example, represent under the situation of baseball in the 1st playback information that is transfused to, as shown in figure 30, because the weight coefficient of number of times importance degree, interval importance degree, length importance degree, reproduction speed importance degree, switching number importance degree is respectively α 1=1.5, α 2=1.5, α 3=1, α 4=0.5, α 5=1, so the importance degree R1 of the playback 1 of Fig. 5 is:

R1=α 1 (number of times importance degree)+α 2 (importance degree at interval)+α 3 (length importance degree)+α 4 (reproduction speed importance degree) α 5 (switching the number importance degree)=1.51+1.5120+120+0.51+11

＝203

According to same step, the importance degree R3 of the importance degree R2 of the playback 2 of Fig. 5 and playback 3 is as follows.

R2＝1.5·1+1.5·105+1·15+0.5·1+1·1

＝175.5

R3＝1.5·1+1.5·50+1·25+0.5·1+1·2

＝104

The importance degree that playback importance degree computing unit 30 will be obtained like this adds the 2nd playback information and makes additional importance degree playback information (Figure 28), it is outputed to summary make unit 40 (step 6).

And certain personage that the value of the weight coefficient shown in the regular setting table of tax power is made as in broadcasting station side or receiving platform side can set.Personage in the broadcasting station side has carried out can providing the summary of same tendency to the user under the situation of setting.On the other hand, the personage in the receiving platform side has carried out can making the summary of the hobby of also considering the user under the situation of setting.And, also can upgrade the value of weight coefficient, so that can make the summary of hobby by broadcasting station example or receiving platform side.

Summary makes unit 40 in the combination of the subsidiary importance degree playback information that obtains, and selects with immediate and importance degree by the specified length of the summary conditional information of user's operation input and make summary info (step 7) for maximum combination.And detailed step and Figure 12 or step shown in Figure 15 that summary at this moment makes in the unit 40 are identical.

Under the situation of Fig. 5, if will be made as 40 seconds by the length of the summary of summary conditional information appointment, these five of being combined as of playback " only resetting 1 " that then converged to 40 seconds " only resets 2 " " only resetting 3 " " playback 1+ resets 2 " " playback 2+ reset 3 ", the summation of each playback importance degree is as follows.

" only reset 1 ": 203

" only reset 2 ": 175.5

" only reset 3 ": 104

" playback 1+ resets 2 ": 378.5

" playback 2+ resets 3 ": 279.5

Its result selects " the playback 1+ playback 2 " of the summation maximum of playback importance degree, and their playback is arranged according to time series, makes summary info.

The output unit 50 of receiving terminal 200 is obtained and is exported summary and makes the summary info (step 8) that unit 40 makes.According to this summary info (Fig. 9), in this broadcast video that from receiving terminal 200, accumulates, can show the summary that is no more than appointed length by only showing successively to the playback of video till the finish time between service area of resetting from the zero hour between the playback service area of summary info appointment.

Like this, in this summary creating method, the structure of the playback importance degree computing unit shown in the execution mode 1 to 4 is separated, and be divided into broadcasting station side and receiving platform side, the calculating of the importance degree of number etc. is switched in the number of times of resetting in the broadcasting station side, structure, the length of time, broadcasting speed or montage, on the other hand, carry out calculating at receiving platform to the importance degree of this playback information, so can between two devices, share the calculating of the importance degree of each playback information, and, can make the summary info of the hobby of also having considered the user etc.

And, in the present embodiment,, also can obtain by twocouese communication though the 2nd playback information that receiving terminal 200 is obtained obtains to communication by folk prescription.Promptly, in central means 100, also can in database (not shown), manage the 2nd playback information that calculates by the 1st playback importance degree computing unit 31, and asking to obtain after the 2nd playback information from 200 pairs of central means 100 of receiving terminal, thus, can between two devices, make a summary efficiently and make processing.

And, in the present embodiment, make the operation input of the summary conditional information obtained in the unit 40 at the summary of receiving terminal 200, but also can obtain the summary conditional information of setting in central means 100 sides by the user.Can make the summary info that converges at the summary conditional information of central means side or the setting of receiving terminal side in either case.

And, in the present embodiment, with " the 1st playback importance degree computing unit 31 ", " the 2nd playback importance degree computing unit 32 " be located away from " central means 100 " respectively, " receiving terminal 200 " is illustrated, but much less, they also can be worked in same device, as above-mentioned execution mode 1 explanation.

In addition, playback importance degree Calculation Method also can be the method beyond the method shown in the execution mode.For example, for the interval importance degree that calculates from " between the playback service area and reset ", only be subjected to the influence of the time band that incident takes place with the importance degree of its Difference Calculation with reference to interval interval.That is, as shown in figure 31,, can not correctly reflect importance degree at interval even identical incident is shorter at interval than the playback in preceding half incident that produces in the playback of the incident of the later half generation of match.Therefore, the remaining time of the broadcasting of also can considering to compete, come the counting period importance degree by following calculating formula.And, for the calculating of the importance degree at the interval of expression in the above-described embodiment, be that difference multiply by constant (1), multiply by logarithm but also can be made as.

(formula 1)

Importance degree=(assigned position between the playback service area-playbacks is with reference to interval assigned position) at interval/(assigned position in programme televised live finish time-playbacks reference interval) of resetting

And, for the interval importance degree that calculates from " between the playback service area and the interval interval of reference of resetting ", resetting, use continuously under the situation between the playback service area, promptly with reference to interval repetition, under the situation of the playback of broadcasting similar events as continuously, shown in figure 32, the interval importance degree of the playback information of using in the back strengthens the length part in the playback of preceding use at interval, although must give the interval importance degree of identical value, be calculated significantly.Such playback is inferior from the various angles three such situations of scene of shaking of taking by force of resetting in baseball, is repeatedly broadcasted, but is not just important in the playback of back use.Therefore, using continuously under the situation of playback with reference to the interval of similar events as, in order in the calculating of the playback interval of such situation importance degree, not produce mistake, the zero hour is broadcasted in the playback that initial playback broadcasting is considered as continuously the incident of use the zero hour, and the calculating of importance degree at interval of resetting is set like that.

And, though the playback of using after incident mainly is used to emphasize this incident, if but set between the playback service area and reset big more then importance degree is calculated big more parts with reference to interval interval, then as shown in figure 33, the value of the interval importance degree of the playback of using after incident is calculated lessly.Incidents such as " excellent matches (fine play) " or " take by force three shake scene " in the playback of using after incident, is arranged, though these are not the incidents that match is directly exerted an influence, the incident of can be used as is utilized.Therefore, also can utilize this threshold value with each playback of video/voice packets between the playback service area and reset with reference to the interval setting threshold of interval assigned position.That is, divide into groups by utilizing preset threshold, can the different playback of video/sound of distinguishing characteristic.For example, under the situation littler of between the playback service area and the interval of the interval assigned position of reference of resetting than threshold value, make the match that comprises the excellence after the incident or take three groups that scene etc. resets of shaking by force, on the other hand,, can make and comprise the group that begins the playback of the flow process of competing from incident at interval than threshold value under the big situation at this through certain playback of using more than the time, i.e. expression.So, for example, want to do excellent in pairs match or take three by force and shake under the situation of the summary that scene payes attention to the user, to the playback of the playback of video/sound in corresponding group at interval importance degree multiply by the coefficient of regulation and set importance degree at interval than the highland.On the other hand, under the situation of wanting to make the summary of having considered that also match is whole, to the playback of the playback of video/sound in corresponding group at interval importance degree multiply by the coefficient of regulation and set importance degree at interval than the highland.Thus, utilize looking hearer or the summary person of making etc. and can obtaining summary info of summary implementing device corresponding to the clip Text of hope.

And, the playback that after programme televised live finishes, is broadcasted, for example the broadcasting in news program or the sports cast is intervened program significantly and is weaved into, and between importance degree and playback service area and the reference interval of resetting is disproportionate.Therefore, as shown in figure 34,, do not distinguish the importance degree at interval of resetting, be redefined for the importance degree of identical value for the playback information after the programme televised live end.Just, the playback that finishes back broadcasting at programme televised live all is considered to important playback, so for the playback information after the live end, better than the numerical value of highland setting importance degree in advance.That is,, need individually to set in advance the computational methods of importance degree at interval in the programme televised live front and back of the finish time.

And, in the above-described embodiment, be illustrated with reference to the interval zero hour and the zero hour between the playback service area " at interval " importance degree of playback of video being carried out differential situation, but also can realize the differential of importance degree according to other " at interval " according to resetting.For example, also can be with reference to middle " at interval " constantly between interval and playback service area that the importance degree of playback of video is differential according to becoming playback.

And, in the above-described embodiment, be that many situation is illustrated to the photography video camera, still, shown in Figure 13 (a), video camera also can be 1.At this moment, shown in Figure 13 (b), in playback information, do not need to comprise the information of photography video camera number.And then the importance degree of playback information also can be differential owing to the number (the shooting direction of video camera) of the video camera of taking playback of video.And also the effect that can show by the picture size or the CG of the playback of video that shown by sprite is differential with importance degree.

More than, summary creating method of the present invention and program can be implemented in this makes a summary implementing device, and, stipulate that the program of the action of summary implementing device of the present invention can be recorded in the recording medium, thereby shift or copy to other device.
