Herein, Fig. 6 is the key diagram that an example of broadcasting schedule and broadcasting prolongation table is shown.In this execution mode 1, for ease of explanation, output as shown in Figure 6, according to content A → content B → content C → content D → content E → ... order, the broadcasting schedule that various content A ~ N is broadcasted.
If broadcasting prolongation table generator 5 receives broadcasting schedule from Promgramming device 2, then with reference to this broadcasting schedule, generate denoting contents receiving system 6 can from broadcasting supplementary device 4 via communication network 7 disperse downloading contents A ~ N during broadcasting prolongation table, this broadcasting prolongation is shown to broadcast.
Below, specify the contents processing of broadcasting prolongation table generator 5.
If the broadcasting prolongation broadcasting schedule obtaining section 31 of table generator 5 has been exported broadcasting schedule (the step ST51 of Fig. 5) from Promgramming device 2, then obtain this broadcasting schedule, and this broadcasting schedule is outputed to broadcasting prolongation table generating unit 32(step ST52).
If broadcasting prolongation table generating unit 32 receives broadcasting schedule from broadcasting schedule obtaining section 31, then with reference to this broadcasting schedule, generate denoting contents receiving system 6 can from broadcasting supplementary device 4 via communication network 7 disperse downloading contents A ~ N during broadcasting prolongation table (step ST53).
Can download scheduled broadcast content during the zero hour be the off-the-air of this content after.
For example, be that broadcasting from content A begin through the moment of T1 time (from the moment of the broadcasting that begun content A through certain hour after) as shown in Figure 6 the zero hour during can downloading contents A, is the T2 time during can downloading contents A.
Therefore, be that the broadcasting from content A began through the moment of T1+T2 time the finish time during can downloading contents A.
In the example of Fig. 6, for replenishing regularly, the broadcasting that makes content A ~ N disperses, and not overlapping during each among content A ~ N can be downloaded, during certain, only can download a content.
If broadcasting prolongation table generating unit 32 has generated broadcasting prolongation table, then broadcast prolongation table broadcasting section 33 and be modulated to broadcast wave by broadcasting the prolongation table, and send this broadcast wave, to a plurality of these broadcasting prolongation tables (step ST54) of content reception apparatus 6 broadcasting.
If broadcaster of content 3 receives broadcasting schedule from Promgramming device 2, then with reference to this broadcasting schedule, the content A ~ N of identification scheduled broadcast obtains the content A of scheduled broadcast ~ N from content server 1.
If broadcaster of content 3 has obtained the content A of scheduled broadcast ~ N, then according to this broadcasting schedule, the content A of scheduled broadcast ~ N is broadcasted.
That is, broadcaster of content 3 is by being modulated to broadcast wave with the content A of scheduled broadcast ~ N, and sends this broadcast wave, to the content A of a plurality of content reception apparatus 6 broadcasting scheduled broadcast ~ N.
In the example of Fig. 6, according to content A → content B → content C → content D → content E → ... order, A ~ N broadcasts to content.
In addition, content reception apparatus 6 receives from the content of broadcaster of content 3 broadcasting.
At this moment, 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 the broadcasting prolongation table from table generator 5 broadcasting of broadcasting prolongation, can download this content during in, from the non-reception part of broadcasting supplementary device 4 downloading contents.
For example, envision the following state of affairs: because the reason such as weather and wave condition worsens, thereby a plurality of content reception apparatus 6 that certain region has occured to belong to can't normally receive in the situation of situation of content A, B, C, belong to a plurality of content reception apparatus 6 of this region from broadcasting supplementary device 4 together downloading contents A, B, C.
But, in this execution mode 1, so that the simultaneously mode of the state of affairs of downloading contents A, B, C of a plurality of content reception apparatus 6 not to occur, allow to downloading contents A, B, C during disperse.
Below, specify the contents processing of content reception apparatus 6.
If the broadcast wave receiver 11 of content reception apparatus 6 receives the broadcast wave (the step ST31 of Fig. 3) that sends from broadcasting prolongation table generator 5, then broadcast prolongation table from this broadcast wave demodulation, and should broadcast the prolongation and show to output to broadcasting prolongation table obtaining section 12(step ST32).
If broadcasting prolongation table obtaining section 12 has been exported broadcasting prolongation table from broadcast wave receiver 11, then obtain this broadcasting prolongation table, and will broadcast the prolongation table record to inner memory (step ST33).
Next, if broadcast wave receiver 11 receives the broadcast wave (step ST34) that sends from broadcaster of content 3, then from this broadcast wave demodulated content A ~ N, and this content A ~ N outputed to content obtaining section 13(step ST35).
If content obtaining section 13 has been exported content A ~ N from broadcast wave receiver 11, then obtain this content A ~ N, and be recorded to the 14(of content record section step ST36).
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.
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).

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.
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.
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.
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
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.
