If content obtaining section 13 is recorded to content record section 14 with content A ~ N, then normally receive detection unit 15 by for each of content A ~ N, such as the continuity that checks this content etc., determine whether normally to have received content A ~ N(step ST37).
, for ease of explanation, be made as for content D ~ N herein, normally receive, but content A, B, C normally do not receive and describe.
With the result of determination that normally receives detection unit 15 output to can download during determination portion 16, download beginning regularly determination section 19 and content reproducing unit 22.
Thus, although be identified as can reproducing contents D ~ N for content reproducing unit 22, current time can not reproducing contents A, B, C, even hypothesis waits the regeneration indication that receives content A, B, C from user, do not accept this regeneration yet.At this moment, also can be before constructing complete content A, B, C during, the information such as the meaning that can't regenerate are shown in not shown display.
If normally receive the meaning (step ST38) that the result of determination of detection unit 15 represents normally to receive content A, B, C, the broadcasting prolongation table that records in determination portion 16 internal storage with reference to broadcasting prolongations table obtaining sections 12 during then can downloading, determine to download this content A, B, C during (step ST39).
In the example of Fig. 6, passed through the zero hour during can downloading contents A moment of T1 time the zero hour from the broadcasting of content A, from this zero hour through the finish time during can downloading contents A moment of T2 time.
In addition, passed through the zero hour during can downloading contents B moment of T1+T2 time the zero hour from the broadcasting of content A, from this zero hour through the finish time during can downloading contents B moment of T2 ' time.
In addition, passed through the zero hour during can downloading contents C moment of T1+T2+T2 ' time the zero hour from the broadcasting of content A, from this zero hour through T2 " finish time during can downloading contents C moment of time.
Randomizer 18 for example is configured to can downloading contents A(or content B, content C) during in, a plurality of content reception apparatus 6 do not begin simultaneously content A(or, content B, content C) download, the random value (step ST40) as random number occurs.
For example, " X " occurs and as random value R in the randomizer of certain content reception apparatus 6 18, and the randomizer 18 of other guide receiving system 6 " Ys " different from " X " occurs and as random value R.
Download beginning timing determination section 19 for example in the situation that downloading contents A, in during being determined by determination portion during can downloading 16 (time T 2 during), according to the random value R that occurs from randomizer 18, determine the beginning regularly (step ST41) of download of the non-reception part of this content A.
For example, during can downloading contents A in, the beginning that makes download regularly Tm is separated in 10 the situation, adjusts in the mode of generation random value R the scope of " 0 " ~ " 9 " in.
Then, by with random value R substitution following formula, calculate the beginning timing Tm that downloads.
Tm=T1+T2×R/10
In addition, in the situation that downloading contents B, during being determined by determination portion during can downloading 16 in (time T 2 ' during), according to the random value R that occurs from randomizer 18, determine this content B non-reception part download beginning regularly.
In addition, in the situation that downloading contents C, during being determined by determination portion during can downloading 16 in (time T 2 " during), according to the random value R that occurs from randomizer 18, determine this content C non-reception part download beginning regularly.
If download beginning regularly determination section 19 determined content A, B, C download beginning regularly, then download section 20 monitors not shown clock, survey content A, B, C download beginning regularly.
If download section 20 for example detects the beginning timing (step ST42) of the download of content A, then via network interface section 17, the providing of content A that will comprise definite information (for example, the byte number from the beginning of content A and data volume etc.) of the identifying information (program ID) of content A and the damaged part among the denoting contents A requires to send to broadcasting supplementary device 4(step ST43 via communication network 7).
In addition, if detect the beginning timing (step ST42) of the download of content B, then via network interface section 17, the providing of content B that will comprise definite information (for example, the byte number from the beginning of content B and data volume etc.) of the identifying information (program ID) of content B and the damaged part among the denoting contents B requires to send to broadcasting supplementary device 4(step ST43 via communication network 7).
In addition, if detect the beginning timing (step ST42) of the download of content C, then via network interface section 17, the providing of content C that will comprise definite information (for example, the byte number from the beginning of content C and data volume etc.) of the identifying information (program ID) of content C and the damaged part among the denoting contents C requires to send to broadcasting supplementary device 4(step ST43 via communication network 7).
Broadcasting supplementary device 4 is obtained the content A of scheduled broadcast ~ N from content server 1, and put aside this content A ~ N, if the requirement that provides of content is provided via communication network 7 from content reception apparatus 6, then provide the identifying information of the content that comprises in the requirement and definite information of the damaged part in the denoting contents according to this, determine the non-reception part of the content that is desirable to provide, and the non-reception part of this content is sent to content reception apparatus 6 via communication network 7.
Download section 20 is via network interface section 17, from broadcasting supplementary device 4 via communication network 7 downloading contents A(or, content B, content C) non-reception part, with content A(or, content B, content C) non-reception part output to content and construct the 21(of section step ST44).
If content construct section 21 from download section 20 receive content A(or, content B, content C) non-reception part, then obtain in the content record section 14 record content A(or, content B, content C) normal receiving unit.
Then, content construct the 21 combined arrangement A(of section or, content B, content C) normal receiving unit and non-reception part construct complete content, with complete content A(or, content B, content C) be recorded to the 14(of content record section step ST45).
If content construct section 21 with complete content A(or, content B, content C) be recorded to content record section 14, then content reproducing unit 22 such as wait from user receive content A(or, content B, content C) the regeneration indication time or with complete content A(or, content B, content C) timing after just being recorded to content record section 14, from content record section 14 obtain complete content A(or, content B, content C), regenerate this content A(or, content B, content C) (step ST46).
Can know significantly according to this execution mode 1 from the above, be provided with: broadcaster of content 3, according to the broadcasting schedule of airtime of denoting contents, content is broadcasted; Broadcasting supplementary device 4 provides from the content of broadcaster of content 3 broadcasting via communication network 7; And broadcasting prolongation table generator 5, with reference to this broadcasting schedule, generate expression can from broadcasting supplementary device 4 via communication network 7 disperse to download content more than 1 during broadcasting prolongation table, and this table broadcasted broadcasting prolongation, content reception apparatus 6 receives from the broadcasting prolongation table of broadcasting prolongation table generator 5 broadcasting, in the situation that has the non-reception part that can't normally receive the content of broadcasting from broadcaster of content 3, with reference to this broadcasting prolongation table, determine to download this content during, and the timing that randomly decision begins to download within this period, with this regularly matchingly from the non-reception part of broadcasting supplementary device 4 downloading contents, even so play in the situation that can't normally receive a plurality of contents, the download of a plurality of contents is disperseed, and can prevent that communication network 7 from congested effect occuring.
In addition, in this execution mode 1, show and download beginning timing determination section 19 according to the random value R that occurs from randomizer 18, the download that determines non-reception part begins example regularly, but so long as make the download by a plurality of content reception apparatus 6 downloading contents begin regularly to disperse to get final product, also can by the method beyond the random value R that occurs from randomizer 18, determine that the download of content begins regularly.
Execution mode 2.
In above-mentioned execution mode 1, show the broadcasting prolongation table generating unit 32 of broadcasting prolongation table generator 5 with reference to broadcasting schedule, generate expression can from broadcasting supplementary device 4 via communication network 7 disperse downloading contents A ~ N during the example of broadcasting prolongation table, but in the time of also can showing in this broadcasting prolongation of generation, as can download content A from broadcaster of content 3 broadcasting ~ N during, set to the proportional length of data volume of content A ~ N during.
Particularly, broadcasting prolongation table generating unit 32 generates broadcasting prolongation table as described below.
In the situation that broadcaster of content 3 is broadcasted content A ~ N with constant transfer rate, the data volume of content A ~ N is more, and the airtime of content A ~ N is longer.
In addition, the data volume of content A ~ N is more, and the many possibility of the data quantitative change of content reception apparatus 6 during from broadcasting supplementary device 4 downloading contents is high.
Therefore, if the data volume of content is more, make during can downloading longlyer, then the download of content regularly is dispersed, and the data volume that flows in the communication network 7 averages out, and can prevent that communication network 7 is congested.
Therefore, broadcasting prolongation table generating unit 32 will to the proportional length of data volume of content A ~ N during be set as can downloading contents A ~ N during.
That is, the zero hour during can downloading contents A ~ N and above-mentioned execution mode 1 are after the off-the-air of this content similarly, and for example, be through the moment of T1 time the zero hour during can downloading contents A the broadcasting from content A begins.
During can downloading contents A ~ N as mentioned above, be to the proportional length of data volume of content A ~ N during, for example, will be set as and the proportional length of the data volume of content A as the T2 time during can downloading contents A.
Can know significantly according to this execution mode 2 from the above, when broadcasting prolongation table generating unit 32 generation broadcasting prolongation table, during can downloading contents A ~ N, set with the proportional length of data volume of content A ~ N during, can prevent in the congested effect of communication network when broadcasting supplementary device 4 downloading contents 7 so play.
Execution mode 3.
In above-mentioned execution mode 1, show the broadcasting prolongation table generating unit 32 of broadcasting prolongation table generator 5 with reference to broadcasting schedule, generate expression can from broadcasting supplementary device 4 via communication network 7 disperse downloading contents A ~ N during the example of broadcasting prolongation table, but in the time of also can showing in this broadcasting prolongation of generation, as can download content A from broadcaster of content 3 broadcasting ~ N during, set to proportional length of airtime of content A ~ N during.
Particularly, broadcasting prolongation table generating unit 32 generates broadcasting prolongation table as described below.
In the situation that broadcaster of content 3 is broadcasted content A ~ N with constant transfer rate, the airtime of content A ~ N is longer, the capacity of content A ~ N larger (airtime and the capacity of content are proportional).
In addition, the capacity of content A ~ N is larger, and the many possibility of the data quantitative change of content reception apparatus 6 during from broadcasting supplementary device 4 downloading contents is high.
Therefore, if the airtime of content is longer, make during can downloading longlyer, then the download of content regularly is dispersed, and the data volume that flows in the communication network 7 averages out, and can prevent that communication network 7 is congested.
Therefore, broadcasting prolongation table generating unit 32 will to proportional length of airtime of content A ~ N during be set as can downloading contents A ~ N during.
Herein, Fig. 7 is the key diagram that an example of broadcasting schedule and broadcasting prolongation table is shown.
In the example of Fig. 7, (time T 2) is identical during each content in the airtime of setting each content for and the broadcasting prolongation table Downloadable.
The data volume of the time per unit when thus, downloading each content averages out in theory.
In addition, in the example of Fig. 7, time T 2 becomes the time identical with the airtime of each content, and the timing of downloading each content is not overlapping.
Can know significantly from the above, according to this execution mode 3, when broadcasting prolongation table generating unit 32 generation broadcasting prolongation table, during can downloading contents A ~ N, set with proportional length of airtime of content A ~ N during, can prevent in the congested effect of communication network when broadcasting supplementary device 4 downloading contents 7 so play.
Execution mode 4.
In above-mentioned execution mode 3, showing broadcaster of content 3 broadcasts content one by one, broadcasting prolongation table generator 5 with allow to download each content during nonoverlapping mode generate the example of broadcasting prolongation table, but in the situation that broadcaster of content 3 is broadcasted a plurality of contents simultaneously, broadcasting prolongation table generator 5 also can with allow to download a plurality of contents during overlapping mode generate broadcasting prolongation table.
Fig. 8 is the key diagram that an example of broadcasting schedule and broadcasting prolongation table is shown.
In Fig. 8, the example that broadcaster of content 3 is broadcasted 2 contents simultaneously is shown, for example, while broadcasted content A and content M.
At this moment, anticipation is than the conveyer belt of content A ~ E, and the conveyer belt of content M ~ P is wider, so for example, if be conceived to identical content A and content M of airtime, then than the data volume of content A, the data volume of content M is more.
But, the broadcasting prolongation table generating unit 32 of broadcasting prolongation table generator 5 is with reference to broadcasting schedule, during can downloading contents A ~ E, set to proportional length of airtime of content A ~ E during, during can downloading contents M ~ P, set to proportional length of airtime of content M ~ P during.
Therefore, though with allow to download a plurality of contents during overlapping mode generated broadcasting prolongation table, the data volume that flows in the communication network 7 in each time band also averages out, and can prevent that communication network 7 is congested.
Can know significantly from the above, according to this execution mode 4, in the situation that broadcaster of content 3 is broadcasted a plurality of contents simultaneously, the broadcasting prolongation table generating unit 32 of broadcasting prolongation table generator 5 with allow to downloading contents during between a plurality of contents overlapping mode, generate broadcasting prolongation table, and can download each content during be set as to proportional length of airtime of each content during, so play the effect that can prevent that from broadcasting supplementary device 4 downloading contents time communication network 7 is congested.
Execution mode 5.
In above-mentioned execution mode 1 ~ 4, though do not mention especially, be subject to the impact of the rating of this content from the number of units of the content reception apparatus 6 of broadcasting supplementary device 4 downloading contents.
For example, even the reception situation is the content of same degree, if rating is high, then many with the number of units change of the content reception apparatus 6 of downloading contents in the identical time, contrary ground, if rating is low, then the number of units with the content reception apparatus 6 of downloading contents tails off in the identical time.
Therefore, if download continually the high content of rating, then might cause communication network 7 congested.
Therefore, in this execution mode 5, by with allow to downloading contents during the mode that between a plurality of contents (content that the content that rating is high and rating are low), repeats, generate broadcasting prolongation table, frequency to the download of content-based rating in a plurality of contents averages, and realizes the equalization of the data volume that flows in the communication network 7 in each time band.
Fig. 9 is the key diagram that an example of broadcasting schedule and broadcasting prolongation table is shown.
In Fig. 9, repeat the example that repeats during content C and content D Downloadable during showing content A and content B Downloadable.
In the example of Fig. 9, the rating of content B, D is extremely high, and the rating of content A, C is low, thus as the combination that makes the content that repeats during Downloadable, made up content A and content B, and, made up content C and content D.
The broadcasting prolongation table generating unit 32 of broadcasting prolongation table generator 5 when downloading high content B, the D of rating, in order not cause communication network 7 congested, allow to download each content during longer than the airtime of each content.
For example, can downloading contents A and content B during be the T2 time, longer than the airtime of content A, content B.
But, for the broadcasting schedule to other guide not impacts, as can downloading contents A and content B during the T2 time shorter than the airtime T3 of the total of content A and content B.Perhaps, equal the airtime T3 of the total of content A and content B.
T2≦T3
Execution mode 6.
Figure 10 is the key diagram that an example of broadcasting schedule and broadcasting prolongation table is shown.
Broadcaster of content 3 sometimes as shown in figure 10, during regulation (for example, whenever the broadcasting content of 20 programs or set in per 8 hours regulation during) in, the content that repeated multiple times broadcasting is identical.
In the example of Figure 10, during α, with content A broadcasting 3 times, with content B broadcasting 2 times, with content C broadcasting 1 time.
The broadcasting prolongation table generating unit 32 of broadcasting prolongation table generator 5 and above-mentioned execution mode 1 ~ 5 are similarly, the data volume of consideration content, airtime, anticipation rating etc., broadcast the prolongation table and generate, but in during regulation, the content of repeated multiple times broadcasting, in this period, carried out after the last broadcasting, only set can download for 1 time during.
For example, during among the α, content A is broadcasted 3 times, but after having carried out the 3rd time broadcasting, only set 1 time can downloading contents A during.
Broadcasting prolongation table generating unit 32 as mentioned above, become 1 time for during the content that makes repeated multiple times broadcasting Downloadable, for example, than during α broadcasting content number " 6 " (=3+2+1), make a side of relevant with each content number of times " 3 " during Downloadable still less, but so that during the total ascent time T α and relevant with content A, B, the C consistent mode of total ascent time T4 during Downloadable of airtime of content A, B, C among the α, set relevant with content A, B, C Downloadable during.
Tα=T4
Can know significantly from the above, according to this execution mode 6, when broadcasting prolongation table generating unit 32 generation broadcasting prolongation table, the content of during certain, broadcasting from broadcaster of content 3, comprise repeatedly in the situation of the content of broadcasting, be set as the content that can download repeatedly broadcasting during and can download the content of only broadcasting 1 time during total ascent time consistent with the total ascent time of the airtime of all the elements of during certain, broadcasting from broadcaster of content 3, so play and to eliminate that data volume is offset in time from broadcasting supplementary device 4 downloading contents the time, can prevent the effect that communication network 7 is congested.
